Conserving Snake Species of Greatest Conservation Need Threatened by an Emerging Fungal Skin Disease	December 2015	A suspected new fungal skin disease has been identified as a newly emerging threat to snakes, including Species of Greatest Conservation Need such as Massasauga (Sistrurus catenatus) and Timber Rattlesnake (Crotalus horridus) in multiple eastern and Midwestern states. Using data obtained from this regional snake species assessment, the many state partners will utilize an adaptive management framework for development of long-term conservation strategies for up to 40 snake species potentially impacted by the disease. Other conservation actions include evaluation of treatment options, experimental treatment with antifungal agents, captive rearing, and monitoring.	None
Assessing Habitat Occupancy of Tiger Prey in the Hukaung Valley of Northern Myanmar	May 2014	We used results from camera traps set for tigers (Panthera tigris) during 2001-2011 in the Hukaung Valley Wildlife Sanctuary of northern Myanmar to assess overall diversity of large mammal and bird species, and to identify differences in photo rates inside and outside of the most protected core area of the Sanctuary. A total of 403 camera stations were deployed during October-July in the dry seasons of 2001-2011, 260 inside the Core area and 143 Outside. From 10,750 trap-nights I obtained 2,077 independent photos of wildlife species and 699 of domestic animals and humans, including 35 species of wild mammals (19 carnivores, 4 primates, 1 elephant, 6 even-toed ungulates, 1 pangolin, and 4 rodents) and 16 species of wild birds. Of these, 1 is considered critically endangered, 7 are endangered, 11 are vulnerable, and 5 are nearly threatened. Some species that probably occur in the Sanctuary (e.g., arboreal or semi-aquatic mammals) were not photographed, likely because of camera placement. In total, 48 wild species were photographed in the Core area vs. 33 outside of the core area. No photos of any domestic animal species or insurgents were obtained inside the Core area but many more photos of poachers and villagers, but also park rangers, were obtained there. Increased patrol efforts likely helped maintain species presence in the Core area, but differences in photo rates between areas were likely influenced by differences in elevation, slope, density of streams, trails, and roads, and perhaps vegetative cover type. Tiger abundance was most influenced naturally by prey availability and anthropogenically by poaching. In the Hukaung Valley Wildlife Sanctuary in northern Myanmar, a major conservation area established to protect tigers, tiger presence has declined. This study was conducted to assess habitat occupancy and distribution of principal tiger prey species in the Core part of the Sanctuary by surveying for sign on 1651 km partitioned into 554 sampling units during November 2007 and May 2008. Using a standard occupancy model in the program PRESENCE (6.2), habitat occupancy and detection probabilities were predicted and the best candidate model for each species was selected using the Akaike Information Criterion (AIC). By incorporating 7 environmental and 5 social covariates, the predicted habitat occupancy rates were 0.76 (SE=0.196, naïve estimate = 0.5162) for gaur (Bos gaurus), 0.91 (SE=0.03, naïve estimate = 0.7762) for sambar (Rusa unicolor), 0.57 (SE = 0.003, naïve estimate = 0.3195) for wild pigs (Sus scrofa) and 0.89 (SE = 0.001, naïve estimate = 0.7996) for muntjac (Muntiacus muntjak). Overall, shorter Euclidean distances to ranger stations and trails, decreased stream density, and broadleaved evergreen/semi-deciduous forest and relatively rare rain-fed cropland habitat occurrence positively influenced prey habitat occupancy; conversely, shorter Euclidean distances to villages, roads, and streams, higher elevations, and occurrence of mixed broadleaved and needle-leaved forest habitat negatively influenced occupancy. In addition, Euclidean distance to ranger stations, trails, and roads positively affected species detections, whereas shorter Euclidean distance to villages and streams, high elevations, and high precipitation negatively affected detections. Results indicate that all four prey species were relatively abundant and well-distributed through the Sanctuary Core area and likely not a factor limiting tiger abundance.	None
Inventory and Monitoring for the Federally Endangered Northern Red-bellied Cooter	December 2015	The proposed work is necessary to inform recovery efforts for the endangered Northern Red-bellied Cooter. Our work will emphasize on-the-ground management throughout the cooter’s range (conservation delivery) with the objective of downlisting or even delisting the species. Specific deliverables that will be provided by December 31, 2015 are: (1) final field-tested protocols for Visual Rapid Assessment (VRA) surveys, (2) map showing current geographic extent of cooters in southeastern Massachusetts, (3) final field-tested protocols for assessing habitat, (4) map showing high priority areas for habitat management, and (5) report detailing survey results (using VRA and Mark-Recapture studies already being conducted by the Massachusetts Division of Fisheries and Wildlife) and future management and monitoring recommendations. Finalized protocols will allow us to inventory, monitor, and evaluate more sites within the range, and pilot habitat management techniques. Final field protocols for VRA and new maps depicting geographic extent will support outcome based monitoring. In the near term, this information will help us evaluate how well we are meeting our Recovery Plan goals and whether current population levels satisfy downlisting or delisting criteria. In the future, these deliverables will also help us monitor future population changes and help us direct our efforts on-the-ground. Final field protocols for assessing habitat and a map showing high priority areas for habitat management will address conservation design and delivery and ensure we get the greatest biological return with our on-the-ground management. Monitoring at all sites where habitat management is implemented will allow us to measure our success and complete the Strategic Habitat Conservation feedback loop.	None
Movements of Coastal Birds in Southern New England	December 2016	Offshore wind energy is one of the fastest-growing segments of the world energy market, offering a clean and abundant source of electricity to meet growing demands (O’Connell et al. 2009, American Wind Energy Association 2011). However, offshore wind facilities may have detrimental effects on birds, exposing them to increased mortality through turbine collisions and altering behavior, habitat use, and movement patterns (Drewitt and Langston 2006). Several wind energy facilities are currently being planned for offshore Atlantic waters of the United States. Under Federal laws, regulatory agencies such as the Bureau of Ocean Energy Management (BOEM) and the U.S. Fish and Wildlife Service (USFWS), have an obligation to protect populations of marine birds that frequent these areas (O’Connell et al. 2009). In the eastern U.S., BOEM has specific jurisdiction over offshore waters beyond three nautical miles (approximately 5.6 km) of shore (hereafter “Federal waters”). To assess the potential for detrimental effects to marine birds posed by wind turbines in Federal waters, there is a need to collect information on distribution and behavior (e.g., flight paths, timing) from a broad suite of birds in these areas, particularly for species of conservation concern. Studies that use telemetry to track individual birds provide spatial and temporal data on flight paths and distribution, which is needed to identify how birds use areas where wind facilities will be located prior to their construction. This baseline information is essential for evaluating negative interactions between birds and offshore turbines (e.g., displacement from critical foraging habitat, increased collisions) that could occur after an offshore wind facility is built. A better understanding of interactions between birds and operational wind facilities in Federal waters can improve siting procedures for future facilities. In situations where specific siting decisions have not yet been made, tracking information can also be used to identify where high concentrations of birds occur and better understand factors (e.g., seasonality, food, weather) that influence their distributions, allowing regulators and managers to place future offshore wind energy facilities in areas with the lowest predicted impacts (Drewitt and Langston 2006, O’Connell et al. 2009, Burger et al. 2011). Our study will complement other work that is underway or being planned by BOEM, USFWS, and other agencies as part of a comprehensive evaluation of the potential for interactions between wind energy facilities and wildlife within Federal waters of the U.S. Atlantic. For example, we are already collaborating with the Northeast Regional Migration Monitoring Network (NRMMN), a research group whose aim is to understand the migration of birds and bats in the Gulf of Maine region in anticipation of offshore wind project development. We will also continue to assess and refine automated NanoTag tracking technology, laying a foundation for expansion of similar research southward to the mid-Atlantic, and other sections of Federal waters in upcoming years. Pending the outcome of our pilot research, an expanded “Atlantic Flyway Monitoring Network” of automated telemetry stations and NanoTagged coastal and marine birds, land birds, and bats would provide regulators with comprehensive data needed to better assess offshore habitat use and movement patterns of flying wildlife in the offshore environment. Such information will be critical for making decisions about where to site proposed offshore and coastal wind energy facilities in the future to minimize adverse impacts on wildlife.	None
Conserving Wood Turtles and Associated Riparian Species	June 2017	The wood turtle (Glyptemys insculpta) is a riparian and terrestrial species of conservation concern throughout its range in northeastern North America. The wood turtle occurs discontinuously from Nova Scotia to Iowa and south to Virginia and West Virginia. Because of its terrestrial tendency and life history characteristics (low recruitment rates and late [15-18 years] sexual maturity), it is particularly vulnerable to habitat loss, fragmentation, and other anthropogenic sources of mortality that lead to population decline. Biologists and land managers have expressed concern for over thirty years that the wood turtle appears to be declining throughout its range, with abundant evidence of decline reported from the Northeastern States and adjacent areas. Quantifiable evidence of decline has increased substantially since the 1990s. The primary causes of population decline arew associated with habitat fragmentation and habitat degradation and are generally attributed to automobile roadkill and crushing of adults by farm machinery, collection of wild animals for domestic and foreign pet markets, and other sources. As a result of this concern, the wood turtle was upgraded from “vulnerable” to “endangered” by the IUCN in 2011, and from G4 to G3 (vulnerable) by NatureServe (2010), underscoring the urgency of the situation. In Canada, the wood turtle is listed as “threatened” by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) and the Species at Risk Act (SARA). The wood turtle is listed as a species of greatest conservation need (SGCN) in the Wildlife Action Plan (WAP) of all thirteen northeastern states (NEPARC 2010), and has twice been proposed for federal listing by independent petitioners. The wood turtle has been identified as an extremely high-value focal species for landscape scale conservation in the northern forest, of high regional responsibility and concern by Northeast Partners in Amphibian and Reptile Conservation, and it is a representative species by the North Atlantic Landscape Conservation Cooperative. Successful management of this highly sensitive and at-risk species will require aggressive coordination and strategic planning, with a strong emphasis on sustained implementation. Successful conservation and management of riverine and riparian habitats for wood turtles will also benefit several dozen species of SGCN across the Northeast Region.	None
Offshore Movements of Migratory Bats in the Gulf of Maine	December 2017	Wind energy development is promoted by both government and nonprofit entities as an environmentally friendly alternative to greenhouse gas-emitting fossil fuels, but the technology can have negative impacts on wildlife, including bats (GAO 2005). Overall, a recent study estimated 600,000 bats were killed by wind power in the United States in 2012 (Hayes 2013). As wind power facilities expand and multiply, concern is growing that wind farm mortality could have significant effects on bat populations at large (Cryan 2011). The effects of wind development on bat populations may be especially detrimental to migratory tree and foliage-roosting bats, which comprise about 75% of all fatalities reported in North America (Arnett et al. 2008). In the northeastern United States, long-distance migrants include the hoary bat (Lasiurus cinereus), the eastern red bat (L. borealis), and the silver-haired bat (Lasionycteris noctivagans). These species face the greatest risks during their fall migration southward, with mortality at wind farms peaking during this season (Arnett et al. 2008). Little is known about the timing, routes, or drivers of migration in these species, or why they are particularly vulnerable to wind farm mortality during fall migration. Migratory activity in bats has been associated with nights of low wind speeds and the passage of storm fronts, as is the case for migrating songbirds (Arnett et al. 2008), but information about speed of migration, on a nightly and seasonal basis, stopover timing, and stopover location are lacking. Major bat migratory pathways in the northeastern U.S. have not been identified, but European bats follow linear features, including coastlines, when migrating (Serra-Cobo et al. 1998, Lesinski 2008, Ahlen et al. 2009, Furmankiewicz & Kucharska 2009) and songbirds often follow coastal routes during migration, so it has been hypothesized that North American bats may follow similar pathways (Cryan 2003, Johnson et al. 2011). Recent acoustic surveys in the Gulf of Maine have found activity of migratory bat species to be higher in coastal areas compared to inland sites (Stantec 2012), supporting the idea that coastal areas may serve as migratory pathways. In addition, there is a century-long historical record of migratory bat activity over the open ocean, sometimes at great distances from shore. Migratory bats utilize marine islands as stopover sites (Cryan & Brown 2007, Johnson et al. 2011), and have been observed visiting barren rocks 30 miles off the coast (Merriam 1897) and roosting on ships at sea (e.g. Nichols 1920, Thomas 1921, Griffin 1940, Corbet 1970). Acoustic surveys documented migratory bats flying over marine buoys on numerous occasions during the migration season (Stantec 2012). Taken together, these observations indicate that coastal and offshore areas, which face significant wind energy development in the near future, may serve as important habitat for migratory bats. Given the dearth of information about bat migration in general, and migration in coastal and offshore environments in particular, further research is needed in order to understand how best to site and operate coastal and offshore wind facilities to minimize bat mortality.

Establishing long-term, continuous monitoring of flow, temperature, and macroinvertebrates at reference streams to quantify potential effects of climate change on stream ecosystems	December 2017	Climate change is altering temperatures and flows in stream ecosystems, which can affect the distribution, diversity, and abundance of biotic communities that are used as a basis for resource management. The lack of continuous temperature and flow data for minimally disturbed, unregulated freshwater wadeable streams is an impediment to analyses of long-term trends in biological, thermal, and hydrologic data. Recently, USEPA has been collaborating with east coast states to develop regional reference/climate change monitoring networks that can detect small, progressive changes in stream communities. States in the northeast (CT, ME, MA, NH, NY, RI, and VT) have begun monitoring macroinvertebrates; however, continuous monitoring of temperature (air and water) and hydrology have been limited thus far. To help facilitate more uniform and effective collection of continuous temperature and water depth data, the US EPA and collaborators have developed a guidance document for sampling ungaged sites in wadeable streams. This document addresses equipment needs, installation, maintenance, stream discharge measurements, data retrieval, and data processing. In November 2014, we will hold a 1.5-day workshop for northeast state participants in the reference network and other interested stakeholders on continuous monitoring of stream temperature and flow.

The longitudinal extent of thermal alteration downstream of impoundments in Massachusetts streams	June 2015	River and stream impoundments are a pervasive feature of the American landscape. Dams and impoundments offer a multitude of societal benefits: water supply, flood control, electricity, and more (Bednarek 2001; Martinez et. al 2013). Impoundments may be natural or man-made, and vary in both purpose and design (Collier et. al 1996). Unfortunately, despite their benefits, impoundments often have many detrimental effects on stream ecosystem health. One of the most ecologically significant impacts impoundments have on stream and river systems is changes in the thermal regime. Impoundments have the effect of upsetting the natural regime of temperatures in a stream (Bednarek 2001). The impact impoundments have on riverine temperature is variable and dependent on multiple factors, including how the impoundment is operated and the depth from which the water that is impounded is released (Ward 1985). Temperature changes occur at a dam because of the unnatural pooling of water behind the impoundment (Petts 1984). When impounded, water in a stream or river begins to behave more like it would in a lake. Lake habitats are characterized by slow moving water and larger surface areas, causing temperatures to stratify with higher temperature waters resting on the top layer (Bednarek 2001). If this upper layer spills over the impoundment or is intentionally released, downstream temperatures are altered from their natural state (Bendarek 2001). This is often the case in small impoundments, like those found above streams, where downstream temperatures are increased through the release of warm water directly from the surface of a reservoir (Olden and Naiman 2010). In larger operations, water may be released from the lower, hypolimnetic layer of the impounded water, causing decreased temperatures downstream from the impoundment (Olden and Naiman 2010). The objectives of this research are to: 1) Quantify the longitudinal extent of the impact impoundments have on downstream temperature. 2) Compare the longitudinal temperature changes downstream of four different types of impoundments: run of river (ROR), drawdown, water supply, and beaver dams. 3) Determine the role topography, land cover, and discharge play in the longitudinal extent of thermal alteration in streams below impoundments.

Urbanization and Massachusetts streams: Unpacking the biological effects of impervious cover	June 2017	Many recent papers have synthesized the negative effects of urbanization and impervious cover on stream ecosystems. Although these responses to urbanization are widely documented and often strong, there are so many possible mechanisms that specific proximate causes are often difficult to distinguish. This is partially because both natural and anthropogenic factors influence the responses at different locations, but also due to a lack of understanding of specific stressors. The general relation between watershed impervious cover and most indicators of stream quality is often represented by a cone that progressively narrows with increasing impervious cover. The high variability in responses at low levels of impervious cover may be explained by factors unrelated or partially related to impervious cover, such as local in-stream habitat modifications, water-quality impairments, altered thermal regimes, and land-use history. Reach-scale habitat and water quality have been shown to be important stressors of biological assemblages. Thus, quantifying in-stream characteristics is important for predicting biotic responses to urbanization and understanding mechanisms of impairment. The goal of this research is to investigate fish and macroinvertebrate responses to regional, local, and in-stream environmental factors within narrow ranges of watershed impervious cover. Specific objectives are to: 1. Assess in-stream physical and chemical conditions (habitat, water quality, and temperature) in streams with similar watershed impervious cover 2. Identify landscape characteristics (natural and anthropogenic) at regional and local scales that predict in-stream physical and chemical characteristics 3. Identify linkages between landscape characteristics, in-stream physical and chemical characteristics, and fish and macroinvertebrates assemblages in streams with similar watershed impervious cover The development of landscape variables and predictive modelling in Objectives 2 and 3 will take place in conjunction with USGS New England Water Science Center (WSC). Overall, the research will help to better understand the mechanisms of impairment and stream response and recovery trajectories.	None
Investigating alewife population dynamics and parent-progeny-relationships in the Parker River towards determining landscape effects on productivity	June 2016	River herring [collectively alewive (Alosa pseudoharengus) and blueback herring (Alosa aestivalis)] have undergone a dramatic decline in landings over the past 5 decades that has resulted in their petition for listing on the Endangered Species Act (ESA). During the ESA process many data gaps were identified including a better detailing of production within freshwater habitat. Traditionally, alewife restoration success and run management has revolved around maximizing the total number of adults entering a nursery system. While aiming for maximum return appears to be a positive approach, there are no data to suggest that high adult returns guarantee strong juvenile production. Previous results have suggested there is likely an asymptotic relationship, where there is a limit to the number of adults that will add to juvenile production, perhaps due to food availability in nursery habitats (Havey 1973, Walton 1987). Furthermore, adult run strength has limitations as a metric for managing harvest in the new ASMFC Sustainable Fishery Plan context, as data required to forecast run strength and determine cohort dynamics are often not available. Understanding of the relationship between number of alewife spawners and juvenile production is critical for setting appropriate management goals for either restoration or harvest. Past efforts to estimate spawner-recruitment relationships have not been entirely successful but have laid the groundwork for a more comprehensive investigation. Since even the most recent study (2006, reported in Gahagan et al. 2010), monitoring technology using video and digital counting has greatly improved, thus allowing researchers to realistically create census counts at greatly reduced cost in hours. The counts created with this technology are also continuous, allowing for concurrent environmental measurements to be directly related to estimates of migration. We believe the development of these technologies and judicious site selection will maximize our ability to control system dynamics, measure juvenile production, and provide adequate power to identify environmental drivers of growth, mortality and movement. A genetic component to the project will provide important and innovative information regarding the contribution of individuals to production. This concern addresses information from Maine suggesting that the production potential of nursery lakes can be “saturated” by the reproductive output of some number of adults. Escapement-based management plans in harvested runs operate on the premise that there is an optimal density of adults to pass into spawning habitats, usually a percentage of the total run. However, this requires knowledge about relative importance of escapement, temporal spacing of spawning events and whether specific portions of the run are particularly important, and whether productivity in ponds is limited by food-web, landscape or other biological characteristics. Negative consequences due to few individuals contributing to subsequent generations, namely, loss of genetic diversity, inbreeding, and reduced adaptive potential (Hare et al. 2011), may occur without managers’ knowledge in the absence of the information we propose to collect. This project seeks to fill critical alewife knowledge gaps by studying the ecosystem properties and evolutionary mechanisms that interact to control alewife productivity in coastal lakes. We will stock adult alewives in lakes where they have been extirpated and quantify juvenile production through sampling resident and migrating age-0 individuals using a variety of traditional and novel approaches. We will consider multiple metrics including number of spawners, number of successful spawners (determined genetically), environmental conditions in the lake throughout the growing season, food availability in nursery areas, and demographic characteristics of age-0 fish over the season. Finally, we will sample alewives in multiple ponds and lakes to assess landscape-scale variables influencing alewife presence and densities.	None
Spatial and temporal variation of stream insect emergence in headwater streams	May 2014	This study is examining spatial patterns of aquatic insect emergence within headwater streams in Massachusetts. The overall goals of the project are 1) to investigate timing and spatial distribution of aquatic insect emergence, and 2) to further characterize the biodiversity of headwater streams. In spring 2013, adult aquatic insects will be collected from emergent structures, open water, and other substrates within the streams. We will compare 1) emergence density between locations within the stream, and 2) timing of emergence among species. The data will be used to inform the larger River’s Calendar project, a citizen science project led by the UMass Water Resource Research Center in which anglers are gathering data on insect phenology as an indicator of climate change.

Making decisions in complex landscapes: headwater stream management across multiple agencies	May 2016	There is growing evidence that headwater stream ecosystems are especially vulnerable to changing climate and land use, but their conservation is challenged by the need to address the threats at a landscape scale, often through coordination with multiple management agencies and landowners. This project seeks to fill a gap, providing an example of cooperative landscape decision-making to address the conservation of headwater stream ecosystems in the face of climate change. We will facilitate a structured decision making (SDM) process with agencies that have joint management authority in a shared landscape, to frame their decision context. In each of the watersheds (Potomac River Watershed, Merrimack River Watershed), we will work with management partners (USFWS, NPS, USFS) in a framework that mimics an LCC, but at a smaller scale. The SDM process will involve: (a) preliminary one-on-one conversations with the management agencies to begin to understand their perspectives; (b) a facilitated workshop with the joint management agencies in a watershed (FWS, NPS, USFS) to frame the decision context; (c) development of decision support tools, such as predictive models of species response to management, based on the context identified; (d) subsequent meetings and communication to evaluate the relevance of the support tools; and (e) documentation and training so the managers know how to use the products of this research for decision implementation. The decision-framing itself, as well as the decision-support tools (like predictive models) are important products that will be directly relevant and usable by management agencies. In addition, we will document the findings and process in several publications.	None
Investigating Impacts of Winter Lake Drawdowns on Littoral Ecosystems	December 2019	In Massachusetts, there are about 200 small reservoirs that are drawn down in the fall and refilled in the spring as an approach to kill aquatic vegetation. Massachusetts Division of Fisheries and Wildlife is interested in understanding the effects of these drawdowns on fish and wildlife that use the lakes. The project will begin with a literature review of the effects of lake drawdowns on fish and wildlife, and an assessment of the scope (location, timing, amount, rate, etc.) of drawdowns in Massachusetts. This will be followed by a field project assessing the impacts of drawdowns on lake fauna.	Anthropogenic alteration of water levels in lakes is a major stressor to the ecological integrity of littoral zones, which provide critical heterogenous resources that support diverse biological communities. Annual winter drawdowns have used in Massachusetts (MA) for several decades as a macrophyte control technique, among other purposes; however, few studies have estimated impacts to littoral zone habitat and biological communities, particularly at relatively mild magnitudes (i.e., <2 m). This collaborative project with the Massachusetts Division of Fisheries and Wildlife will characterize winter drawdown hydrological regimes and estimate responses of physical habitat (macrophytes, sediment texture, coarse wood), macroinvertebrate assemblages, and mussel assemblages to variable levels of drawdown magnitude. Results are critical for understanding the scope of drawdowns in Massachusetts and will more broadly assist agencies in evaluating lake management techniques and determining management options that minimize losses to lake ecosystem integrity.
A heads up view of aquatic ecosystem sustainability: understanding the terrestrial landscape scale impacts of urbanization on aquatic biota	August 2015	This work on environmental and societal sustainability has two main objectives: 1) Examine how patterns of stream fish and insect community composition relate to watershed-scale versus landscape-scale land-use patterns. 2) Examine how land-use development scenarios impact the suitability of land acquisition strategies for conserving stream fish and insect communities. Objective 1 takes a multi-scale approach to understanding how land-use patterns relate to stream fish and insect community structure by using existing community data and GIS analysis of land-use patterns. Objective 2 will take an interdisciplinary approach to understanding how different land acquisition strategies benefit stream fish and insect populations while maintaining economic growth and societal needs. The work will incorporate land-use development models. The results from objective 2 will be transformed into a decision-support system (DSS) developed to aid agency personnel with land acquisition activities.	None
Plum Island Ecosystems LTER	June 2018	This project examines spatial and temporal distribution, movements, and trophic function of striped bass. This research matters because top fish predators have important impacts on aquatic ecosystems and are popular sportfish prized by anglers. Thus, understanding distribution, diets, and movements of mobile fish predators, like striped bass, provides foundational insights that helps our fisheries management cooperators set science-based harvest limits. The partners for this research are the National Science Foundation. My 17-year research program on these highly motile predators has allowed me to develop a series of increasingly complex scientific questions that have management implications. For example, my research started with simple striped bass distribution-feeding relationships, progressed to using acoustic telemetry to assess local movements, tested mechanisms for mobile predator aggregations, evolved to examine coastal movements, and advanced to making connections across ecosystems. Most recently, my team has tested integrated seascape distribution patterns, quantified how geomorphic features (such as confluences) influence seascape distribution, assessed multi-scale site fidelity, and identified individual distributional groups. This research informs decisions by advancing spatially-explicit frameworks for fisheries management.

Population Size and Distribution of Sumatran Rhinoceros	September 2014	Sumatran rhinoceros were once distributed from the Himalayas to Sumatra, Indonesia, but currently have been extirpated from most their historical range. The world population of Sumatran rhinoceros is estimated to have decreased from 600 animals in 1985 to less than 300 in 1995 with the current population believed to be around 200 individuals. On the island of Sumatra, the location with the largest number of Sumatra rhinos in the wild, animals are distributed among 3 discrete populations, but to date, no systematic surveys have been conducted to estimate the population size of rhinos at these locations. We will assess the distribution of Sumatran rhinoceros on Sumatra using the data from an island-wide large mammal patch occupancy survey along with a Sumatran rhino survey conducted in Gunung Leuser National Park. We will estimate the change in occupancy, and the local extinction and colonization rates, with the overall goal of guiding the the conservation of Sumatran Rhinos in the wild.	None
Ant Diversity in Pine Barrens of the Northeast	May 2014	Pine barren ecosystems of the Northeast are globally rare and little is know about the potentially unique ant communities that may be supported there. This study will describe the diversity of ant species inhabiting the pine barrens of New York and Massachusetts with the goal of shedding light on ant communities of sandy soils throughout the Northeast.

Understanding the factors that influence outdoor residential water conservation: a case study in suburban Boston	September 2015	In the face of recent droughts and climate change impacts, water conservation is critical for meeting water demands of humans and freshwater ecosystems. Since residential landscaping is a major component of domestic water use, efforts to promote outdoor residential water conservation are critical. Water harvesting using rain barrels, infiltrating stormwater using rain gardens, and landscaping with native plants have been promoted through outreach campaigns as a means to reduce water use and provide ecosystem benefits. There is a need to understand how these recent water conservation outreach efforts impact local residents’ attitudes towards and behaviors incorporating these low-impact development (LID) strategies, and subsequently lead to measureable improvements in water conservation and ecosystem health. In addition, it is important to understand the formal and informal role the green industry plays in promoting residential landscape water conservation. Our project aims to trace watershed conservation measures from policy incentives to impact so as to develop a clearer picture of the relationship between local policy and outreach efforts, and actual decisions to engage and install residential landscape water conservation and stormwater management strategies. The project goals are: 1) to identify local policy and outreach efforts across the watershed and to evaluate connections between those and the adoption of LID practices, 2) to explore the factors that influence local residents’ decisions to engage in low impact development strategies to conserve domestic water and manage stormwater, 3) to understand the connection between adoption of water conservation practices and actual water quantity savings at the household and watershed scales, and 4) to enhance local agencies’ outreach efforts to promote LID and water conservation tools and techniques that are readily adopted by local residents and provide the greatest benefit for the environment and human well-being.

Impacts of Surface Water Supply Reservoirs on Stream Flow and Biota	June 2024	In 2010, the Massachusetts Sustainable Water Management Initiative (SWMI) was created to develop a water allocation program that satisfies human water needs while protecting aquatic ecosystem health. The current framework includes a safe yield approach to allocation, biological categorization of streams using fish communities as a surrogate for aquatic integrity, and streamflow criteria (http://www.mass.gov/eea/docs/eea/water/framework-draft-feb03-2012.pdf). The approach for setting streamflow standards was based on estimates of flow alteration indicators (based on groundwater withdrawals and discharges), and relationships between estimated flow alteration and fluvial fish assemblages. Although the SWMI process is continuing with existing data, researchers identified the lack of information about flow alteration due to surface water withdrawals from reservoirs as a major information gap.<br><br>The overall goal of this research is to quantify flow alteration due to surface water withdrawals from reservoirs and the relationship between in-stream flow and biotic assemblages downstream of water supply reservoirs. This project involves collecting stream stage, fishes, and macroinvertebrates downstream of water supply reservoirs, and comparing that to non-supply reservoirs and unimpounded streams. We will select streams with similar size watersheds, but varying levels of water withdrawal. Streams will be continuously gaged with pressure transducers, and we will compare actual flows with the monthly withdrawals reported by the water suppliers. We will also investigate relationships between flow and temperature alteration, fish assemblages, and macroinvertebrate assemblages to determine the aspects of the flow and temperature regime that predict biotic assemblages.	Surface water reservoirs used for public water supply are common throughout the landscape and can greatly disrupt stream flow regimes. Predicting effects of water withdrawals on downstream flows and aquatic ecosystems is particularly challenging due to variation in withdrawal and dam management and characteristics of the watershed, reservoir, and streams. This project is a collaboration with the Massachusetts Division of Fisheries and Wildlife. Our hydrologic monitoring in streams will help to understand variability in flow alteration and directly link hydrology to biotic responses, which is critical for making decisions on how to manage water supply while protecting stream ecosystems.
Offshore Wind Energy Technology, Environmental Impacts, and Policy	September 2016	We will address three primary issues that are critical for development and operation of offshore wind energy facilities. These are (1) ecological assessment of the positive and negative impacts of offshore wind power for birds and bats, fish and other marine species; (2) identification of critical areas and habitats for marine organisms using radar, sonar, and spatial modeling combined with experiments to quantify population and community dynamics; and (3) development and evaluation of monitoring protocols and technologies for detecting risks to marine organisms, especially given the unique opportunity to deploy aquatic monitoring equipment. During the 5-year period of this project we will train 25 PhD students across 8 different departments at the University of Massachusetts Amherst.	None
Population Ecology of Sumatran Tigers and Their Prey	December 2005	Sumatran tiger populations in Bukit Barisan Selatan National Park (BBSNP) on Sumatra, Indonesia continue to decline, mainly due to human induced factors such as direct hunting of tigers, prey depletion, and habitat destruction. Using photographs of tigers taken with camera traps, we evaluated tiger abundance in the park based on capture-recapture methods. Our study is the first to quantify the pattern of crop raiding by sambar deer, wild pigs, muntjac, and pig-tailed macaques. We found that the abundance of tiger and sambar deer were significantly correlated. Among environmental variables, elevation was the best predictor of the distribution of tigers and their prey.	None
Small mammal ecology and Lyme disease on Martha=s Vineyard	May 2005	Martha's Vineyard has one of the highest prevalences of Lyme disease in Massachusetts. We tested the effectiveness of bait boxes, which treat small mammals with pesticide, in reducing the prevalence of Borrelia burgdorferi (disease agent) in small mammals and ticks. Deer tick and B. burgdorferi prevalence decreased as a result of the treatment, thus we have identified a useful technique for reducing the likelihood of contracting Lyme disease. This has important implications for reducing human illness and mortality in the region, and across the country.	None
Limitations to the northernmost distribution of Virginia opossums	September 2008	Limitations to the distribution of a species are poorly understood, though this information is critical to understanding the abundance and distribution of organisms. We examined the biophysical limits to the northernmost distribution of Virginia opossums, by examining conditions near Amherst, Massachusetts, where opossums recently expanded their range. In combination with energetic modeling, we have shown that opossums are only able to exist in the Amherst region if they are near human developments where the microclimate is moderated, and food availability is increased. Our findings are useful in understanding how opossums have been able to successfully expand their range as far north as Canada, and have applications to predicting range expansions under global warming scenarios.

Effect of firebreaks on rare insects of M. F. Correllus State Forest, MA	May 2005	Martha's Vineyard is known to have the highest number of rare insect species of any location in Massachusetts, probably due to a lack of insecticide use in the past. We tested several means of expanding firebreaks (cutting, mowing, burning, grazing) to see which techniques are most beneficial to the rare insect species that exist on Martha's Vineyard. We found that a combination of grinding and sheep grazing produces the highest density of scrub oak stems, a requirement of many rare Lepidoptera at the site. These results have broad implications for the management of sandplain Lepidoptera throughout eastern North America.	None
Local and landscape effects on frosted elfins in sandplain communities	August 2008	The frosted elfin is a state-listed butterfly species associated with early successional stages of pine barrens ecosystems, a rare seral stage in Massachusetts. We examined local and landscape predictors of abundance of this rare butterfly, with the aim of improving management for the species and its associated ecological community. We found that larvae of frosted elfins feed on Baptisia tinctoria (wild indigo), that are shaded by single trees in a savannah-like fashion, and that larvae are almost always attended by ants that likely protect them from predation. We are the first to document shade selection and ant-tending in this species, ecological traits with important management implications. The Massachusett Division of Fisheries and Wildlife is currently using our results to direct management for frosted elfins in Massachusetts.	None
Ecology and Conservation of Wood Turtles in the Northeast	December 2013	Wood turtles are declining in Massachusetts, and across many parts of their range in eastern North America. We initiated a study of the movements and habitat use of wood turtles in western Massachusetts, a region which may still contain viable populations of the species. Telemetry data have been collected to aid in constructing an individual-based, spatially-explicit, model of the viability of populations across the state. We found that at least 8% of adult turtles are killed each year by hay-mowing operations, an unsustainable level for a k-selected species. In addition we have developed a model of wood turtle abundance based on stream gradient and flow. Both of these findings are being used to change management for wood turtles in Massachusetts and the Northeast. We are currently conducting a status assessment and developing a conservation plan for wood turtles throughout the Northeastern United States.	None
Status assessment of Laysan and black-footed albatrosses	March 2009	We summarized and synthesized data on natural history, population viability, status, threats, habitat requirements, and geographic distribution for Laysan and black-footed albatross. These results will be used to guide the USFWS as they decide whether to list these species under the U.S. Endangered Species Act. Our recommendations will also be the basis for conservation actions taken by the USFWS and other management agencies. The population modeling we did was novel, and our assessment of North Pacific bycatch is the first of its kind	None
Ecology and Conservation of Short-tailed Albatrosses	December 2012	The short-tailed albatross is an endangered species with a current world population of approximately 3,000 individuals. Almost all birds nest on Torishima Island, 350 miles south of Tokyo, but little is known about how they use the ocean environment. Movement data will be combined with oceanographic data to better understand the variables affecting selection of foraging sites. Also, from 2008-2012 we will be working to re-establish an extirpated colony by translocating chicks from Torishima to Mukojima Island. This work is done in collaboration with the Yamashina Institute for Ornithology, Toho University, Japanese Ministry of the Environment, US Fish and Wildlife Service, and the USGS, Oregon Cooperative Fish and Wildlife Research Unit. Impact: This work has shown that birds travel to the Bering Sea, Gulf of Alaska, and along the west coast of North America following the breeding season. These findings have important implications for reducing albatross mortality resulting from commercial fishing operations in this region. During the past 3 years, we have successfully translocated to Mukojima, and reared to fledging, 40 short-tailed albatross chicks that will hopefully provide the nucleus for re-starting this colony that was extirpated by feather hunters.	None
Guiding conservation of eastern box turtles in Massachusetts	May 2010	Eastern box turtles are near the northern edge of their range in Massachusetts, where they are listed as a species of Special Concern. To help guide conservation action in the region, we have been collecting habitat selection and movement data to build models that predict likely areas that could support viable populations of the species. Our modeling is done at multiple spatial and temporal scales, thus allowing us to develop robust predictions of sites that should be the focus of long-term conservation. Our landscape models were recently used to prioritize box turtle sites for the Massachusetts Division of Fisheries and Wildlife and to complete a conservation plan for the species.	None
Population viability modeling and conservation of Blanding=s turtles	June 2014	We have integrated turtle movement data, habitat selection equations, road data, and other GIS layers to develop an individual-based spatially explicit model of the viability of Blanding's turtle populations in Massachusetts. Our model results have been used to revise the conservation plan we developed for the Massachusetts Division of Fisheries and Wildlife, and we then applied them to the entire Northeast in a collaborative assessment of the status of Blanding’s turtles. This type of population viability analysis is novel for freshwater turtles and incorporates the role of spatial variability.	None
Multi-scale modeling of four-toed salamander habitat preference	December 2012	The four-toed salamander, a small cryptic animal, is infrequently observed in the Northeast, and thus believed to be a rare species in the region. To evaluate whether the species is truly rare, or just difficult to observe, we will use the results from field surveys to build local and landscape models of preferred habitat, and then validate these models by ground-truthing. Results will be used by the Massachusetts Division of Fisheries and Wildlife to direct conservation efforts and determine the status of the species.	None
Effectiveness of road passage structures for freshwater turtles	December 2012	There is strong scientific agreement that the main threat to populations of freshwater turtles is the high rate of road mortality suffered by adults while moving between habitat patches. We have initiated a 4-year study, in collaboration with the Massachusetts Department of Transportation (Mass DOT) and the Massachusetts Division of Fisheries and Wildlife, to experimentally test the effectiveness of various culvert and fencing options to help turtles safely cross roadways. Our results will be used by Mass DOT to decide on the type and number of road passage structures to place along new highways, and how to retro-fit existing roadways in order to reduce turtle road kills. This research is the first of its kind.	None
Foraging ecology of auks at their southern range boundary	December 2011	Matinicus Rock, Maine, supports a diversity of auks, including the southernmost breeding colonies of Atlantic puffins and razorbills, black guillemots, and potentially common murres. Understanding the foraging ecology and at-sea distribution of these species is critical because they serve as indicators of change in the marine environment, and likely forage in waters off of Massachusetts during the non-breeding season, and possibly while feeding chicks. To date, most seabird studies have been conducted within colonies, but recent advances in technology allow us to track birds at sea using satellite telemetry. We will combine analyses of food items brought to chicks, with telemetry locations, in order to better understand the foraging ecology of auks nesting at the southern limit of their distribution. Our results should help managers identify foraging sites of razorbills, help guide placement of offshore wind turbines to minimize impacts to the birds, and perhaps anticipate changes in feeding sites in response to global climate warming.	None
Effects of interacting threats on the survival of long-lived species	August 2009	We are expanding on the traditional use of population viability analyses to include examining interacting threats on the survival of long-lived species, albatrosses. Impact: This is a novel modeling approach with applicability to any k-selected species. No one has documented the multiplicative effect of several simultaneous threats on albatross species, and thus our findings should allow a more accurate assessment of the dangers they face.	None
Feeding behavior and nest site attendance of Atlantic puffins in Maine	December 2011	We have begun gathering data on the foraging behavior of Atlantic puffins in the Gulf of Maine by deploying temperature depth recorders on breeding birds at their nesting colony on Petit Manan Island, Maine. Data from the loggers allow us to estimate the distance to feeding areas, the frequency of diving, and the diving depth of individuals. When these data are paired with information on prey brought to the chicks we are able to develop for the first time, a relatively complete picture of the feeding ecology of this marine bird at the southern limit of its range. Our results should help the USFWS identify foraging locations of Atlantic puffins, and potential corridors of movement that are in need of protection. This is a critical need given the pressure to develop offshore wind farms in the Gulf of Maine, and our need to anticipate changing foraging sites under various global climate change scenarios.	None
Bobcat distribution and movements in a mixed urban-rural environment	December 2013	We are using remote cameras, snow tracking, and radio tracking to determine the distribution, movements, and habitat use of bobcats in the Pioneer Valley of central Massachusetts, an area of mixed urban, suburban, agriculture, and wooded patches.	None
Movements, Site Fidelity, Foraging Ecology, and Roosting Behavior of Ring-billed Gulls in Relation to a Water Supply Reservoir in Central Massachusetts.	December 2013	Concern over potential impacts on water quality by large numbers of roosting gulls using large reservoirs in central Massachusetts prompted this study by the Department of Conservation and Recreation. We are investigating the movement patterns, foraging strategies, and site fidelity of gulls (primarily ring-billed but also herring and great black-backed) in relation to these large and important reservoirs during the non-breeding season. Over 2,000 gulls have been marked with colored, numbered patagial tags, and hundreds of observations have been recorded by project staff and the public throughout much of Massachusetts and all along the east coast. In addition, several birds have been fitted with GPS radios to record their movements. We are also experimenting with ways of influencing and reducing the availability of anthropogenic food resources, such as feeding in parking lots, sewage treatment plants, and landfills.	None
Regeneration of Forest Vegetation in Response to Browsing by Moose and Deer: An Experimental Approach Using Exclosures	December 2027	In cooperation with the Massachusetts Department of Conservation and Recreation, Massachusetts Division of Fisheries and Wildlife, Harvard Forest, and several other groups, we have built 16 sets of experimental exclosures to monitor the response of forest vegetation in relation to browsing by moose and deer. Each site has two 20x20 m fenced treatments (full exclosure with fencing to the ground, and a partial exclosure with fencing two feet off the ground to allow access to deer but not moose) and an unfenced control. We have documented varying responses of woody vegetation based on treatment in the first few years of the experiment. Our goal is to see that this experiment continues for at least the next few decades.	Moose (Alces americanus) returned to southern New England in the late 20th century after a 1-2 century absence. Moose are generalist browsers and, coupled with white-tailed deer (Odocoileus virginianus), can have long-term influences on the structure and composition of forest ecosystems. We set out to understand these relationships by constructing 15 20 x 20 m exclosures in a randomized block design with 3 treatment levels: (1) no-ungulates (full exclosure), (2) deer only (partial exclosure), and (3) deer + moose (control, i.e., no fence). During the first phase of this research, we discovered that in logged forests, moose and deer used the cuts at roughly the same frequency despite moose densities being much lower than deer densities. Moose were the dominant browser and after 6–7 years of browsing, deer + moose reduced stem densities and basal area by 2-3-fold, cherry and oak recruitment by 3–6 fold, and species richness by 1.7 species (19%). Browsing resulted in greater herbaceous species richness and greater woody species richness than ungulate exclusion and deer alone. Our initial results illustrate the complex interactions that two native browser can have on forests, with implications for understanding forest ecological dynamics and timber management. The Massachusetts Department of Conservation and Recreation, Massachusetts Division of Fisheries and Wildlife, Harvard University, Highstead Foundation, and U. S. Forest Service collaborated on this research. We will continue with this long-term study through various stages of forest development. The information will be used by conservation and management agencies to further understand wildlife-forest habitat relationships and the role they play in forest ecology, animal community dynamics, watershed management, and production of timber and other forest products.
Demography and Habitat of Striped Skunks on the Island of Martha's Vineyard	December 2011	Striped skunks in coastal environments have not been studied. We examined their demographic characteristics and habitat use of both natural and anthropogenic habitat features, as well as potential interactions with beach-nesting birds.	None
Salt Drive in Beavers: An Experimental Assessment with Field Feeding Trials	December 2011	Salt drive is an extensively documented phenomenon that affects varied classes of herbivores worldwide. The conditions that are believed to trigger this response in other herbivores are also operant within the foraging ecology of beavers, but salt drive has not been investigated in this species. We used salt treated and untreated sticks of aspen and milled pine to set up feeding trials at several wetlands in Massachusetts. Beavers uniformly consumed all aspen sticks (both treated and untreated, with a slight indication of selecting the salted ones first). However, treated pine sticks were selected over untreated, but only after aspen was consumed. Our results indicate that beavers are attracted to salt, but do not appear to have the same strong drive for salt that other, more terrestrial, herbivores show. This is likely due to a combination of the physiology, diet, and semi-aquatic life history of beavers.	None
Landscape Use by a Re-colonizing Moose Population in Massachusetts	December 2013	Massachusetts is a mix of developed and rural landscapes. The predominate vegetative cover is mid-aged forest of mixed deciduous and coniferous composition; both early successional and mature forest are underrepresented. We are investigating how moose are using this fragmented landscape, examining their use of forest vegetation and wetlands for food and thermal cover and interactions with roads and development.	None
Ecology of Urban and Rural Black Bears in Massachusetts	December 2015	The black bear population in Massachusetts is growing in numbers and expanding its range in the state. Many bears have taken up residence in and around small to mid-sized towns and cities. We are using GPS technology to track and monitor bears as they live among densely population suburban and urban areas as well as more rural locations in central Massachusetts.	None
Status, Movements, and Habitat Use of Moose in Massachusetts	September 2011	Moose have re-colonized much of their historic range in New England. This recent southern expansion has raised questions as to their ability to cope with different forest types, densely populated areas, and higher temperatures. We used GPS collars to track the movements of moose throughout southern New England. Home ranges were between 30-200 sq km, and moose used a combination of young forest for food, mature forest for thermal cover, and wetlands, esp. during calving, while avoiding the densely developed areas. The population is low density but appears stable. Moose-vehicle collisions remain a concern throughout the region.	None
Investigating stream conductivity and effects on benthic macroinvertebrates in the Charles River Watershed	December 2027	Freshwater salinization is a major concern in temperate climates where road salt is used to manage snow and ice on roadways. Our recent work in the greater Boston area showed that impervious cover is the major driver of stream conductivity, although conductivity may be modulated by human behaviors (e.g., sidewalk salting, road sweeping). Sensor data provided evidence that conductivity varies with discharge, with high pulses during winter storms and evidence of dilution during other times of the year. Recently, the Charles River Watershed Association (CRWA) purchased conductivity sensors, and they are deploying them upstream and downstream of potential salt sources (e.g., road crossings) to better understand acute and chronic disturbances. This project will (1) assess effects of road crossings on conductivity across seasons and storms, and (2) compare benthic macroinvertebrate assemblages upstream and downstream of road crossings to understand potential effects of road salt on stream ecosystems.

Prioritizing Actions for Restoring Connectivity and Climate Resilience in the Appalachian Highlands	June 2027	The goal of this project is to develop a holistic, data-driven process for identifying (1) priority watersheds and sites and (2) habitat and connectivity restoration actions. To clearly articulate ecological problems that stakeholders are interested in, we will convene a Structured Decision-Making (SDM) workshop with several stakeholders and decision-makers, including government agencies (federal, state, and local), watershed groups, and other non-profit organizations. Then, we will develop a shared understanding of watershed processes within the system by co-developing a conceptual model of the social and eco-system function. We will use the conceptual model and facilitated meetings to identify management actions that improve future watershed conditions. We will focus on habitat and connectivity restoration because improvements there often result in improvements to other key freshwater characteristics like streamflow, sediment regime, temperature regulation, water quality, and flood plain access. The research will be conducted in the Appalachian Highlands region of Massachusetts (MA), an area with numerous At-Risk and sensitive species, and with great potential to protect and restore critical habitats.

Population assessment, habitat use, and occupancy for multiple freshwater turtle species	September 2028	The U.S. Fish and Wildlife Service (USFWS) is reviewing a petition to list the Blanding’s, Wood, and Spotted Turtles as threatened or endangered under the Endangered Species Act (ESA). Surveys for Blanding’s Turtles were last conducted on Devens Reserve Forces Training Area (RFTA) in the early 1990s and early 2000s, although recent surveys and headstarting on adjacent properties (Oxbow National Wildlife Refuge, Bolton Flats Wildlife Management Area) suggest this area has the largest population of Blanding’s Turtle in the northeast. Given the upcoming listing decisions, new surveys are needed to provide updated baseline population and habitat use information on the freshwater turtle populations at Devens RFTA. Specifically, our objectives are to (1) assess populations status, movement, and habitat use for Blanding’s Turtle using radio telemetry, and (2) conduct presence absence surveys for Spotted Turtle and Wood Turtle on Devens RFTA. Surveys may expand to areas adjacent to the Devens property as well as at the Hansom Air Force Base.	None
NSF: Drivers of infection outbreaks in a temperature-sensitive host-pathogen system	July 2028	Hosts and their pathogens exist in spatiotemporally variable thermal environments, and temperature has been repeatedly shown to impact critical disease quantities, such as contact rates, vector abundance, and recruitment of susceptible hosts. Predicting how a changing climate will impact infectious disease dynamics requires a better understanding of the mechanistic impact of temperature on host-pathogen interactions. Our proposal is focused on how temperature and climate influences in-host infection dynamics in seasonal environments when hosts are sensitive to environmental temperature. Specifically, we will focus on how seasonal temperature variation influences host immune function, pathogen transmission, and host behavior; processes that may be determinants of the timing, magnitude, and extent of seasonal disease outbreaks. We will use the amphibian-<i>Batrachochytrium dendrobatidis </i>(Bd) system, where both host (the Eastern red-spotted newt, <i>Notopthalmus viridescens</i>) and pathogen are sensitive to temperature, to determine the functional relationship between environmental temperature and host and pathogen responses and parameterize models to predict the timing and magnitude of seasonal infection outbreaks. To accomplish these goals, we combine manipulative field experiments with a robust set of field observations (including a 5-year pilot study) to identify mechanisms that underlie the complex temperature relationships in this system. We will develop statistical and mathematical tools that combine data types, account for observation uncertainty, and allow for prediction and validation. Our results will contribute to disentangling the role of host- (i.e., immune response, behavior) and pathogen-related (i.e., development, growth) contributions to the timing and magnitude of seasonal outbreaks.

Connecticut River Migratory Fish	September 2018	Recently much of the popular science literature has focused on the concept of climate change. Thus far, there have been some very simple predictions on how climate change will affect temperature, especially in more northern latitudes. As ectotherms, fish are affected directly by any changes in temperature, which can range from altering foraging, reproduction, metabolism, migration timing, etc. In the Connecticut River, anadromous fish (e.g., Atlantic salmon (Salmo salar), American shad (Alosa sapidissima), sea lamprey (Petromyzon marinus)) are predicted to change migration patterns in relation to climate change. The life cycle complexity of migratory species introduces several unknowns regarding the transitions from freshwater to marine and back, and from tributary to mainstem in some species. The changing thermal regime will be accompanied by changes in discharge as a component of the altered water cycle. Predictions of changes in shorter-term weather patterns include more severe events; e.g., a tornado occurred in Vermont on May 9, 2009 and Hurricane Irene caused major damage in Vermont tributaries in August 2011. This backdrop provides an opportunity to expand on our previous modeling of Atlantic salmon migration in the Connecticut River. We explored how temperature, discharge, and the indirect effects of dams (by creating delays in migration) were related to survival of Atlantic salmon smolts. We worked in this area for several years using data from previous monitoring and research. The final phase of our efforts was to model juvenile American shad migration in response to changing environmental conditions.

In the last phase of this research, we collaborated with Vermont Fish and Wildlife in modeling American shad a mainstem spawner. Our results showed how temperatures and flow regimes can affect juvenile American shad and their success under changing conditions.
Quantifying wetland change following small dam removal in Massachusetts	September 2024	Across the United States and within Massachusetts, the rate of dam removals pales in comparison to the number of dams aging across the landscape. Though intended to protect wetlands and waters, wetland regulations pose an obstacle to efficiently removing dams and restoring free-flowing waters. Because dam removal inherently alters the open water ecosystem as well as contiguous wetlands, those seeking to remove dams must address regulatory requirements under Sections 401 and 404 of the Clean Water Act as well as State and local wetland protection regulations. These regulatory protections do not adequately facilitate ecological restoration projects which may significantly alter existing wetland resources to improve the health of a system in the longer term. Specifically, the dearth of information on wetland response following dam removal has resulted in significant uncertainty for removal practitioners and regulators as they balance the potential ecological benefits and impacts related to dam removal.<br><br>To address this uncertainty, we aim to understand and model how wetland area changes upstream of the impoundment, within the impoundment area, and downstream of the former dam over short (0-2 years) and longer (4-6 years and 9-11 years) durations following dam removal by analyzing 26 small dam removal projects completed in Massachusetts between 2000 and 2012. Additionally, we will evaluate the effect of landscape characteristics and dam removal design on wetland change. We will achieve these objectives through aerial interpretation of aerial imagery and primary permitting data. Our results could describe and set expectations for future wetland change following dam removal, as well as identify dam removal project designs that minimize wetland conversion.

Fish habitat suitability and vulnerability to flow and temperature modification	July 2028	Refugia is important for the survival of coldwater fish species under a changing climate. Refugia provides a space species can inhabit during unfavorable habitat conditions in surrounding areas. Stream temperature and flow are important in defining refugia. Warming stream temperatures during the summer decrease suitable habitat for coldwater fish. Stream flooding and drying can also limit suitable habitat for coldwater fish. However, the potential locations of coldwater fish refuges and the strength of the refugia network (network strength defined by number of refugia and connectivity of refuges) has not been exclusively studied.<br><br>Temperature and flow models are currently being developed to predict how coldwater patches could change under future climate change projections in the Northeast. Our project aims to provide critical information on how biota use coldwater patches and the spatial and temporal extent of refugia needed for populations to persist. We will also examine the vulnerability of fish and mussel species to changes in temperature and flow to develop metrics that managers can use to understand potential climate impacts.	Refugia is important for the survival of coldwater biota under a changing climate. Warming stream temperatures and extreme flows (flooding and drying) can limit suitable habitat, and connectivity barriers (dams, culverts) can prevent access to critical habtiat patches. We are collaborating with MassWildlife to develop projects to better understand how fishes and other biota use coldwater refugia. Increasing our understanding of coldwater refugia on the landscape will allow managers to strategically invest in management and conservation efforts to protect and restore critical habitats and biota.
Mapping wildlife road crossing hotspots	August 2025	Wildlife presents a significant and grave safety hazard on roadways. Each year collisions with wildlife cause numerous accidents resulting in harm to drivers and vehicles. Roadways are detrimental to wildlife both as a source of mortality and as a barrier to movement. MASSDOT is a leader in designing mitigation strategies that protect public safety and connect populations. Despite this, collisions of moose, deer, and bear remain common. This problem is only expected to get worse, and bear population expand towards the Boston metropolitan area, and deer population continue to grow throughout the state. It is therefore imperative that Mass Wildlife and MASSDOT to continue to work together to design mitigation strategies that maintain human health and safety as well as preserve healthy wildlife populations for the sustained use and enjoyment of the people of Massachusetts. We will use and build upon a camera array established in western MA by the Massachusetts Cooperative Research Units and existing telemetry data to map potential wildlife crossing hot spots on roadways in W. Massachusetts that are particularly dangerous for both motorists and wildlife (e.g., I-90, I-91, Rt. 2). This information can then be monitored and used to plan mitigation measures needed make the roadways safer for wildlife and people.

Habitat, connectivity, and viability of a timber rattlesnake metapopulation in southwestern Massachusetts	May 2014	Timber rattlesnakes were once found throughout Massachusetts but currently are restricted to only 5 sites as a result of habitat changes and persecution by humans. To help inform conservation of the species, we have begun to examine the genetic connectivity of the remaining populations, their use of habitats, and the corridors of movement between sites. Because the largest remaining metapopulation in the state is connected to sites in New York and Connecticut, we are working in collaboration with biologists from both of these states. Results of population genetic analyses should inform which corridors of movement need to be maintained and source populations for possible re-introduction of animals to sites where they have been extirpated. Movement data will be used by MassWildlife to identify land parcels in need of protection.	None
Regeneration of Forest Vegetation in Response to Browsing by Moose and Deer: An Experimental Approach Using Exclosures	December 2010	Our primary objectives are to (1) quantify the composition, structure, and regeneration success of woody browse in harvested plots that are (a) protected from all browsing by moose and deer, (b) protected from moose browsing but subjected to deer browsing, and (c) subjected to all browsing from moose and deer; (2) document the amount of browsing on twigs and buds and estimate bud survival in all plot types, and (3) improve our understanding of moose browsing and its importance for the management of forest stands. With the aid of DCR and Harvard Forest personnel, we have established 3 sets of moose exclosures within the Quabbin (Prescott and Dana) and Ware River watersheds and 3 sets on Harvard Forest in Massachusetts. Each set of exclosures is comprised of 4 plots (full, partial, and paired controls). Exclosures were established in upland white pine, oak, and mixed hardwood stands that had been logged within 3-4 months before construction of exclosures. The purpose of this experiment is to determine the long-term influence of moose on the structure and species composition of the forest types. Data collected from exclosures and paired controls will be compared in order to discriminate between the effects of moose browsing and forest community succession. We now propose to build exclosures with our collaborators in the states of Connecticut, New Hampshire, and Vermont. This will greatly increase the scope of the research, make the findings applicable to all of southern New England, and involve the Cooperative Research Unit program in a multistate program of research with important regional management implications.

Optimal Habitat Configuration for Mature-Forest and Scrub-Shrub Birds	October 2010	Declines in populations of mature-forest and scrub-shrub birds have caused concern among managers (King et al. 2006a, Schlossberg and King 2007). Managers have long assumed that promoting either mature-forest or scrub-shrub bird groups involves a direct tradeoff, i.e., managing against the other group. However, recent research indicates otherwise. Early-successional habitat has been shown to benefit forest-interior birds during the post-breeding period (when adults molt) and the post-fledging period, when young birds have left the nest but are still dependent on their parents. Post-fledging birds suffer high mortality, which significantly impacts population dynamics (King et al. 2006b). The habitat needs of many forest-interior bird species apparently switch between the nesting and post-fledging periods (King et al. 2006b). Many post-breeding forest birds use scrub-shrub habitats and some appear to prefer that habitat over mature forest (Chandler et al. In Prep b). Depending on scale and configuration, the positive effects of scrub-shrub habitat availability on survival rates of forest-interior birds�fledglings and post-breeding adults�likely outweigh the relatively minor negative effects on nesting success, especially when renesting rates are considered	None
Synthesizing the contributions of the Northeast to the North American Bat (NABat) Monitoring Program and developing a regional communication plan to facilitate future research	August 2024	In collaboration with the USFWS, in this project, we will synthesize Northeast partner data contributions within priority grid cells and National Wildlife Refuges to gain a better understanding of the information currently available within the NABat database.

At-Risk Species Conservation in the Connecticut River	June 2025	We are investigating ecology and conservation of anadromous river herring and freshwater mussels in the Connecticut River. There are two main components of the project:<br>1) Determine which species of freshwater mussels are using migratory fishes (blueback herring, alewife, American shad, striped bass) as hosts in the Connecticut River. Approaches will include examining temporal and spatial patterns in mussel glochidia infestation, using genetic or morphologic techniques to identify mussel species and develop an identification key, assessing ecological and anthropogenic (e.g. fish passage) ramifications of results, evaluating results in light of emerging benthic habitat and species distribution information, and determining conservation and management implications.<br>2) Develop a standardized approach for sub-sampling aged fish to re-examine scales and determine individual spawning history, and, using the standardized approach, examine existing scale samples (2013-2021) to assess the distribution of annual spawning history and glochidia infestation of the Connecticut River blueback herring population.<br>An understanding of how freshwater mussels use anadromous fish species in this large river will inform conservation and restoration of at-risk freshwater mussel species and river herring.	Freshwater mussels require host fishes for completing their life cycle, and anadromous fishes that only spend a small portion of their lives in freshwater may be important for reproduction and dispersal of mussels. The Connecticut River harbors at-risk and endangered freshwater mussel and river herring species, and an understanding of the spatial and temporal dynamics of mussel glochidia on river herring is important for conservation of both taxonomic groups. This project is a collaboration with the U.S. Fish and Wildlife Service, and will inform river herring management and freshwater mussel restoration decisions in the Connecticut River.
Advancing conservation and restoration of Brook Floater and associated freshwater mussels	December 2024	The Brook Floater (<i>Alasmidonta varicosa</i>) is a stream-dwelling freshwater mussel (Bivalvia, Unionoida), native to the Atlantic Slope of the United States and Canada and has experienced significant population declines throughout its range. The species’ distribution has been restricted to approximately 50% of its historic sites, and local population declines have been observed from Nova Scotia to Georgia. Identified threats include decreased habitat and water quality associated with shoreline and watershed development, habitat fragmentation caused by dams and stream crossings, and potential stochastic events associated with a changing climate. This species has been identified by Northeastern states as one of the most critically imperiled species in the region and was one of the few mussel species identified as “At-Risk” by the US Fish and Wildlife Service in 2021. A range wide, collaborative approach to conservation is needed to reverse the trend of habitat loss and reduce the risk of local and regional extirpations. A nationally competitive State Wildlife Grant involving four funded states was awarded to address this issue. To assist in the coordination of this project, and to serve as a technical lead on project activities, the Natural Heritage and Endangered Species Program (NHESP) of the Massachusetts Division of Fisheries and Wildlife (MassWildlife) has partnered with the Massachusetts Cooperative Fish & Wildlife Research Unit at the University of Massachusetts, Amherst (UMass).<br><br>To increase rangewide cooperative conservation efforts and strategic planning towards reducing further population losses and defining approaches for recovery of Brook Floater throughout the species’ range from Georgia to Nova Scotia. UMass will assist in mussel surveys and habitat assessments to evaluate responses to dam removals for mussel (SGCN) species of greatest conservation need, develop pre-stocking and post-stocking mussel monitoring and habitat assessment protocols to identify and track introduced Brook Floater populations, perform rapid mussel and habitat assessments in Massachusetts and Connecticut to update mussel SGCN distributions, develop multi-species occupancy and detection models using reach- and landscape- scale covariates, and help to maintain the Brook Floater Working Group. Our hope is that State partners will utilize approaches and information outcomes of this grant to assess and maintain populations of Brook Floater and other SGCN using an Adaptive Management Framework and prioritize site-specific actions that will prevent further declines of Brook Floater.

Mitigating the Effects of Prescribed Fire on Eastern Box Turtle Populations	May 2023	Eastern Box Turtle (<i>Terrapene carolina</i>)<i> </i>mortality during prescribed fire is a management concern in Massachusetts and other northeastern states from RI to NJ. Numerous observational and experimental studies have examined fire effects on Box Turtles and Box Turtle populations across their range, finding indications that individual Box Turtles exhibit a range of complex behavioral responses to fire, and that early growing season fires may be most lethal under normal circumstances. However, the effect of fire is highly variable, and likely to influence populations differently based on habitat, landscape connectivity, population structure, season, fuel conditions, and weather. Fire mortality of Box Turtles has been documented in Massachusetts populations from the Connecticut Valley to Cape Cod. In part due to the complexity of the issue, we lack a coherent, empirically informed, locally tested management protocol for Box Turtles in the context of fire management in Massachusetts. We propose to undertake a 4-year intensive field study to build upon the existing body of literature and test specific, relevant hypotheses about the effect of fire on Massachusetts Box Turtle populations.<br><br>The primary objective of this multifaceted study is to evaluate the population-level effects of a range of prescribed fire conditions on Massachusetts box turtle populations, to better identify priority box turtle populations at risk of extirpation or substantial decline resulting from prescribed fire management and to minimize the mortality/morbidity rate through practical modifications where feasible. This study will incorporate new data from a reference box turtle population at Camp Edwards and conduct experimental and observational studies at Camp Edwards and adjacent conserved areas. MassWildlife envisions a focused and practical study with a range of opportunistic and experimental components, recognizing that some of these objectives are subject to the frequency accessibility of prescribed fire events and the cooperation of fire managers.

Strategic confiscation and placement of illegally collected turtles for maximizing conservation outcomes	July 2025	The US Fish and Wildlife Service, working with state and federal agencies with regulatory authority over turtles in the northeastern U.S., makes decisions about the confiscation and disposition of multiple species of turtles encountered via legal and extra-legal trade routes. Illegal collection of wild animals for the pet trade has resulted in population declines (Stanford et al. 2020), and U.S. freshwater turtles are particularly vulnerable to illegal collection (Mali et al 2014). Decision-makers wish to maximize the conservation status of turtle populations in the wild, which are declining (or locally extirpated) in part because of illegal harvest, but also because of other threats such as climate change, urbanization, and disease. The decision is complicated by risk to both individuals and populations, primarily of the disease and genetic (i.e., originating-recipient population mismatch) status of confiscated turtles. <b><u>Here, we propose to use tools from decision analysis and population viability analysis to frame and address this problem.</u></b> We will use wood turtles as a case study, as a model species listed under Appendix II of CITES (at risk for extinction given current levels of trade). The USFWS and partners will use this analysis as a basis for expanding this case study for other turtle species of trade concern (spotted turtles, eastern box turtles, Blanding’s turtles, and diamondback terrapins). The analysis and approach we propose will improve coordination in repatriating or releasing confiscated turtles to the wild.

Applications of structured-decision making to disease systems	February 2027	This work involves collaborating with federal and state agencies with decision-making authority to improve the long-term management of CWD, Bsal, and WNS. Work involves helping agencies frame the decision they face within their jurisdiction, and identify management alternatives, knowledge gaps, and optimal decisions. Potential partnerships include scientists from the USGS Fort Collins Science center, USGS National Health Center, and USGS Northern Rocky Mountain Science Center (Paul Cross and colleagues), among others.<br><br>Management of most diseases are challenging because of trade-offs among important management objectives, uncertainty in the dynamics of the disease, some risks that are well understood and some that are not, jurisdictional overlap, disjunct authorities, and potentially different tradeoffs in individual decisions made by Federal, Tribal, State, and private management entities. Over the past several decades, there are several diseases of great concern in the United States, which include chronic wasting disease (CWD), the salamander killing fungus (Bsal), white-nose syndrome (WNS), SARS-CoV-2, and others. <b>In this proposal, our objective is to frame and analyze the decisions for several disease systems, as well as develop models for supporting surveillance and management decisions other disease systems for their management on federally and state managed lands.</b><br><br>For example, it is well documented that CWD has spread across Wyoming and was detected for the first time in Grand Teton National Park in the fall of 2020.

Automated Real-Time Analysis of Bald Eagle Nest Camera Imagery Using Machine Learning: with applications for investigating food resource use and nesting ecology in urbanized landscapes.	December 2022	Bald eagles populations are increasing rapidly in the lower 48 United States. As habitats become saturated, eagles are expanding into novel environments and encountering human stressors. We seek to use bald eagle nest cameras to quantify and monitor forage and demography throughout the urban-rural gradient. The volume of data provided by camera monitoring requires the development of machine-learning algorithms that once trained, will eventually be able to create demographic and provisioning data in near real time. Our project seeks to build and pilot novel computer vision tools using remote camera footage.	Bald eagles populations are increasing rapidly in the lower 48 United States.

Scales and drivers of variability in dissolved organic carbon across diverse urban watersheds	April 2024	A critical gap for ecosystems science is that human activities alter the spatial and temporal scales of existing ecological processes and introduce novel sources of ecological variability. Most ecosystems worldwide are impacted by human activities; yet the effects of human activities across scales are not adequately represented by existing ecosystem models. This is especially true for models of aquatic carbon (C) cycling and fluxes. Only recently has the magnitude of fluvial C fluxes been recognized within the global carbon cycle; yet these estimates explicitly ignore the influence of human activities, such as urbanization. We propose to assess urbanization effects on dissolved organic carbon (DOC)—the largest flux of carbon in streams—focusing on how urbanization affects ecosystems in regionally-specific ways. <u>We hypothesize that human activities introduce novel sources of ecological variability and affect the spatial and temporal scales of ecological processes differently in different geographies and urban contexts</u>. We will test this hypothesis using a comparative approach to understand urban effects on DOC. We will collect data on DOC quality and dynamics at 600 sites across five urban study areas to develop a multi-scale understanding of the quantity and quality of DOC in urban systems. We will use spatial statistics and time-series analyses to identify key spatio-temporal characteristics of human development (e.g., wastewater infrastructure, housing density) and biophysical factors (e.g., discharge, precipitation, canopy cover) that control the concentration, characteristics, and bioavailability of DOC. Our research takes a <i><u>novel approach</u></i> to jointly consider how the human and ecological dimensions of ecosystem ecology interact to control the quality, quantity, and timing of DOC entering watersheds across the continent.	Rivers and the landscapes through which they flow vary widely in both human factors (e.g., wastewater infrastructure, housing density, impervious surfaces) and biophysical factors (e.g., discharge, precipitation, temperature, canopy cover). Over a 12-month period, 100 sites in the Charles, Mystic, and Neponset Rivers in the Boston urban area will be sampled to determine how human and biophysical factors and their interactions influence dissolved organic carbon (DOC) and stream function. Sampling locations in tributaries and rivers are being selected to reflect gradients in factors such as canopy cover, housing density, environmental justice communities, age of development, impervious land cover, and wastewater infrastructure. This project is a collaboration between USGS and University scientists, along with local partners. Together with samples collected in four other urban areas (Atlanta, GA; Miami, FL; Salt Lake City, UT; Portland, OR), these data will lead to better understanding of human and biophysical controls on DOC across urban rivers and provide important information for carbon budgets and river management.
Landscape drivers of freshwater mussel assemblages and imperiled species status: implications for optimal allocation of conservation effort within the Delaware River Basin	May 2023	The Delaware River provides an ideal case study for developing a basin-wide conservation strategy for imperiled freshwater mussels in the North Atlantic-Appalachian Region. The watershed contains 12 species of Atlantic slope mussels (Blakeslee<i> et al.</i> 2018), including the federally endangered Dwarf Wedgemussel and the at-risk Brook Floater. Nearly 15 million people depend on its water supply, and propagation of freshwater mussels is actively being pursued by conservation groups to aid water quality improvements in the estuary. The variation in dominant stressors throughout the basin, from environmental flow issues in the upper basin to water quality issues and saltwater intrusion in the lower basin, coincide with documented shifts in mussel community composition (Blakeslee<i> et al.</i> 2018). These complexities require a deliberative and transparent process to identify robust and collaborative conservation strategies. Our research activities will help foster a basin-wide perspective on mussel conservation and identify collaborative strategies for implementation by federal, state, and non-governmental groups working in the Delaware. The approach to assessing threats and prioritizing actions will be transferable to other watersheds with similar mussel assemblages. <br><br>The overarching goal of this project is to develop a framework to inform decisions on the allocation of conservation effort across potential actions and watersheds to advance freshwater mussel conservation in the Delaware River Basin. This will be achieved through a structured decision-making process to identify robust conservation strategies, combined with predictive modeling of existing data to understand the local and landscape stressors affecting mussel community resilience throughout the basin. Specifically, this project seeks to:<br>1. Identify portfolios of freshwater mussel conservation actions based on national recommendations, locally identified objectives, and feasibility<br>2. Develop predictive models of the stressors and conservation efforts affecting freshwater mussel resilience and community structure<br>3. Integrate multi-attribute tradeoff analysis with empirical models to inform spatial application of freshwater mussel conservation actions	The overarching goal of this project is to develop a framework to inform decisions on the allocation of conservation effort across potential actions and watersheds to advance freshwater mussel conservation in the Delaware River Basin.

Implementation of the bog turtle conservation plan for the northern population	June 2023	The Northern Population of Bog Turtle (<i>Glyptemys muhlenbergii</i>) was federally listed in 1997 due primarily to habitat loss, fragmentation, and degradation (USFWS 2001). Bog Turtle populations are still vulnerable to decline and further imperilment. Further, the Bog Turtle is listed as “Endangered” under the Massachusetts Endangered Species Act (MESA) and its implementing regulations. The Massachusetts Natural Heritage and Endangered Species Program (NHESP) of the Division of Fisheries and Wildlife (MassWildlife) has partnered with six other state wildlife agencies (Delaware, Maryland, Pennsylvania, New Jersey, New York, and Connecticut) on a Competitive State Wildlife Grant (CSWG) to implement a regional Conservation Plan (Erb 2019) that was also developed with CSWG funds. At present, there are only two known occupied Bog Turtle sites in Massachusetts (Sites A and B). At least two additional sites are believed to be historic localities for Bog Turtles in Massachusetts. Incidental observations, available habitat, and regional patterns in adjacent New York and Connecticut indicate that there are likely areas of Bog Turtle occurrence in Massachusetts that are not currently known. This project is intended to support regional conservation planning efforts in coordination with adjacent and northeastern states, to document the spatial ecology of known populations, and to more fully document the distribution of the species in Massachusetts.<br><br>Our primary objective as a seven-state collaborative funded through CSWG is to protect and maintain the Northern Population of Bog Turtle and its habitat through implementation of high priority conservation actions identified in a 2001 recovery plan, the individual state Wildlife Action Plans, and a recently developed (funded via a prior Competitive State Wildlife Grant #F16AP00001) Bog Turtle Conservation Plan for the Northern Population (Erb 2001). Specifically in Massachusetts, our primary objectives are to document the distributional extent of the species in the Commonwealth, identify areas of potential habitat for restoration and/or surveys, to conduct habitat management, and to monitor the effects of habitat management while contributing data and information to the USFWS, the regional conservation planning effort, and the state’s endangered species program.	The Northern population of Bog turtle has been federally listed as a threatened species since 1997 and is listed as “Endangered” under the Massachusetts Endangered Species Act. There are two known sites currently occupied by Bog turtles within the state, with two additional sites believed to have been historically occupied. As the species continues to face threats of habitat loss, fragmentation, and degradation the populations of the two known sites have been studied on a 10-year rotation since the early 2000’s with supporting research being conducted since the 1980’s. The overall goals of this project are to examine the current population status within the known sites, habitat available at each site, extent of habitat used, and search for other potentially occupied sites. This project is a collaboration with the Massachusetts Division of Fisheries and Wildlife and The Nature Conservancy. As one of the longest-running studies on the species, these data will contribute to a regional database to help inform priority habitat management projects for the Bog turtle.
Rethinking lake management for invasive plants under future climate: Sensitivity of lake ecosystems to winter water level drawdowns	December 2024	Small lakes are important to local economies as sources of water supply and places of recreation. Commonly, lakes are considered more desirable for recreation if they are free of the thick weedy vegetation, often comprised of invasive species, that grows around the lake edge; this vegetation makes it difficult to launch boats and swim. In order to reduce this vegetation, a common technique in the US northeast and midwest is a ‘winter drawdown’ (WD). In a WD, the lake level is artificially lowered (via controls in a dam) during the winter to expose shoreline vegetation to freezing conditions, thereby killing them and preserving recreational value of the lake. However, this practice can impact water quality (including prevalence of harmful algal blooms) and native aquatic plants and animals in lakes. Moreover, studies show that WDs are not always effective at killing nuisance and invasive plants. Almost no research has been done to study how WDs interact with climate; wet years, droughts, and heavy snow winters will all have different effects on the effectiveness of the WD at killing vegetation and the impacts on lake ecosystems. This research will specifically investigate WD standard practices and understand how, when, and why WDs can be better managed in differing climates. Further, we will map WD lakes across the entire northeast and midwest regions for the first time, providing policy makers with a first-ever estimate of the total number of WD lakes, the total amount of water released by these lakes (via new hydrology models we will build), and the prevalence of harmful algal blooms. This research will give state and local governments and lake managers a much-needed scientific basis for managing lakes, to ideally to optimize water quality and macrophytes for both human use and ecosystem integrity under future climates.	Human acceleration of eutrophication through continued watershed and lakeshore development, combined with changes in temperature and climate, increasingly challenges managers to meet human needs while protecting aquatic resources. While annual winter water level drawdowns (WDs) are commonly used to reduce nuisance macrophyte biomass, the future utility and impacts to ecosystems under climate change remains uncertain. Moreover, the timing and magnitude of drawdowns, which are influenced by climate, affect the negative impacts of drawdowns on lake ecosystems and water quality, including harmful algal blooms. Using remote sensing data, validated with on-the-ground water level and cyanobacteria data, <i>we will characterize water level fluctuations and cyanobacteria blooms in WD lakes coupled to novel hydrologic models that assess sensitivity of WDs and vulnerability of cyanobacteria blooms to future climate and precipitation. </i>The results from this research, which will be shared in scientific publications and online data repositories, will help evaluate WDs as a macrophyte management tool under future climate change and weigh any remaining benefits with the ecological and socioeconomic costs of performing WDs. This research is a collaboration between the USGS, UMass Amherst, USEPA, and seven state agencies, who will provide in-kind support for compilation and collection of field data and translate results into guidance for lake managers.
Yellow Lampmussel Habitat Assessment in the Connecticut River	April 2025	The Yellow Lampmussel (YLM), <i>Lampsilis cariosa</i>, is a freshwater mussel that has been declining throughout its range and is considered endangered in many states, including Massachusetts and Connecticut. Informal comparisons across boundaries have revealed that YLM populations occur in a variety of habitats throughout its range. However, little is known about the microhabitats that exist within the Connecticut River or their association with YLM. Mapping these fine-scale habitat features using side-scan sonar could illuminate this relationship. A goal of this project is to associate habitat characteristics within the Connecticut River and YLM presence/absence. A highly-accurate, fine-scale habitat assessment using side-scan sonar could be invaluable for land managers within the Connecticut River watershed and beyond.<br>An understanding of host fish for YLM is also essential for understanding the species’ historic and current distribution and developing conservation plans. Striped Bass (<i>Morone saxatilis</i>) is a piscivorous fish that may be a suitable host for YLM; it is closely related to a confirmed host fish species. Observations of YLM glochidial infestation in wild populations of Striped Bass with a large sample size, combined with successful encystment and metamorphosis in laboratory conditions, would confirm this species as a viable host fish. This would have important implications for the conservation of YLM, with Striped Bass serving as a critical source of long-distance dispersal across drainages.	Yellow Lampmussel (<i>Lampsilis cariosa) </i>is a priority at-risk freshwater mussel species for the USFWS and has been designated as endangered or another special status in many states, including MA and CT. Yellow Lampmussel populations occur in a variety of habitats throughout its range; the species inhabits a variety of substrates and flow conditions, suggesting impacts by different stressors. This project aims to assess potential locations for Yellow Lampmussel conservation action within the Connecticut River watershed based on mussel densities, host fish densities, and mussel habitat requirements. This project is a collaboration with the U.S. Fish and Wildlife Service, the Massachusetts Division of Fisheries and Wildlife, and the Connecticut Department of Energy and Environmental Protection. Results from this project may be useful for identifying target areas for novel surveys or candidate areas for release of propagated or relocated Yellow Lampmussel.
Using Aerial surveys to estimate trends in brown bear population dynamics at Katmai National Park and Preserve, Alaska	August 2025	Katmai National Park and Preserve, Alaska hosts one of the world’s largest protected populations of brown bears (<i>Ursus arctos</i>), their habitat, and critical food sources. To monitor this population Katmai collected counts of bears as they fed at salmon streams for decades. Using these stream counts to make inference about the status and trend of bear population or make effective management decisions is complicated by a host of challenges associated with index count data. We will improve inference from these legacy data by using replicate surveys to estimate detection probability. We will then use the legacy stream counts to examine bear population dynamics by combining them with other data in an integrated population modeling approach.	Current brown bear monitoring at Katmai National Park and Preserve, Alaska uses index counts of bears feeding at salmon streams. Using these data to support management decisions presents a number of challenges: 1) counts are biased low because they do not account for imperfect detection; 2) the representativeness of the bears using salmon streams is unknown. We will overcome these challenges using replicate surveys and an integrated population modeling framework. This project is supported by staff and internal funding at NPS and the Katmai Conservancy. The results will be used to support park management manage visitor access and prevent bear-human interactions.
Effects of habitat, density, and climate on moose and winter tick ecology in the northeast US	February 2025	Moose (<i>Alces alces</i>) populations in the northeastern US have declined by over 50% in the past 15 years. Winter tick (<i>Dermacentor albipictus</i>) infestations are a major driver of moose population trends, negatively affecting both survival and reproduction. We will partner with cooperators in Maine, Massachusetts, New Hampshire, New York, and Vermont to measure winter tick and moose distribution and abundance on a large camera trapping array. We will use our data to evaluate moose-tick dynamics across the full distribution of moose in New England. In doing so we can examine the relative importance of climate, habitat, and moose density in driving damaging epizootic conditions.

A risk assessment of chronic wasting disease in Massachusetts and the proactive development of a communication strategy for MassWildlife and wild cervid stakeholders in Massachusetts	September 2025	Emerging infectious diseases like Chronic Wasting Disease (CWD), force decision-makers to make decisions in the face of large uncertainty and risk. Under these pressing circumstances, two important tactics and tools for decision-makers are: (1) obtaining buy-in from stakeholders and (2) formal risk assessments, which predict the potential distribution of a novel pathogen in new habitats. In an effort to prevent CWD from spreading into Massachusetts (MA), the MA state wildlife agency, The Massachusetts Division of Fisheries and Wildlife (MassWildlife), is implementing several proactive management strategies (e.g., regulations to restrict whole carcass importation of deer, improving and focusing on standards for cervid farming); however, it is unclear whether there is stakeholder buy-in or how effective this management is. Therefore, to address these barriers, we propose:<br>(1) To assess existing wild cervid stakeholder perceptions, behaviors, and misconceptions using a survey. We will develop and disseminate a survey that reaches 9,500 wild cervid stakeholders in MA.<br>(2) To examine patterns and trends related to wild cervid stakeholder perceptions, behaviors, and misconceptions, we will analyze the data obtained from the wild cervid stakeholder survey (obj. 1). This will enable us to extract patterns and trends.<br>(3) To identify areas of high risk for CWD introduction, establishment, and spread in MA, we will conduct a risk assessment based on host and prion ecology.<br>(4) To obtain wild cervid stakeholder buy-in and trust, we will:<br>- update the MA CWD response plan with the results of the wild cervid stakeholder survey (obj. 1 & 2) and the risk assessment (obj. 3),<br>- develop a communication strategy that will be used to help MassWildlife engage more regularly with wild cervid stakeholders, and<br>- disseminate the results of the wild cervid stakeholder survey (obj. 1 & 2) and the risk assessment (obj. 3) to wild cervid stakeholders as applicable.<br>Collectively, our objectives aim to promote transparency and open the lines of communication between the state of MA and wild cervid stakeholders. More specifically, this proposal aims to engage wild cervid stakeholders prior to CWD invasion, generate a communication strategy based on what wild cervid stakeholders are seeking (and using the modalities of communication they prefer; learned from the survey), and obtain stakeholder buy-in for proactive and reactive CWD management.

This will enable us to extract patterns and trends.<br>(3) To identify areas of high risk for CWD introduction, establishment, and spread in MA, we will conduct a risk assessment based on host and prion ecology.<br>(4) To obtain wild cervid stakeholder buy-in and trust, we will:<br>- update the MA CWD response plan with the results of the wild cervid stakeholder survey (obj. 1 & 2) and the risk assessment (obj. 3),<br>- develop a communication strategy that will be used to help MassWildlife engage more regularly with wild cervid stakeholders, and<br>- disseminate the results of the wild cervid stakeholder survey (obj. 1 & 2) and the risk assessment (obj. 3) to wild cervid stakeholders as applicable.<br>Collectively, our objectives aim to promote transparency and open the lines of communication between the state of MA and wild cervid stakeholders. More specifically, this proposal aims to engage wild cervid stakeholders prior to CWD invasion, generate a communication strategy based on what wild cervid stakeholders are seeking (and using the modalities of communication they prefer; learned from the survey), and obtain stakeholder buy-in for proactive and reactive CWD management.
FRAMEWORK FOR PROTECTING AQUATIC BIODIVERSITY IN THE NORTHEAST UNDER CHANGING CLIMATES	December 2024	Our objective is to incorporate existing climate change research into a framework that evaluates the conservation of aquatic biodiversity under a suite of land protection and restoration scenarios. We will translate existing Northeast Climate Adaptation Science Center (NECASC) products into formats that can be concurrently analyzed and incorporated into novel methods for biodiversity protection in the Northeast. The goal of this work is to identify land protection and restoration actions that optimize aquatic biodiversity protection into the future. We will evaluate potential changes to biotic assemblages with changing climates and identify management actions most likely to mitigate impacts from climate change. Importantly, the tool developed will be scale-able, allowing managers at small scales (e.g., towns) to prioritize climate adaptations within their jurisdiction. The project will be completed in two phases over the course of two years. In Phase I, objectives are to 1) gather and translate all NECASC research applicable to aquatic ecosystems and 2) define standardized aquatic biodiversity metrics (e.g., species richness, community evenness) for the states of New Hampshire (NH), Vermont (VT), Massachusetts (MA), and Connecticut (CT). In Phase II, we will evaluate the amount of biodiversity protected by alternate scenarios of land protection and habitat restoration in the face of climate change.

Improving management and surveillance decisions related to white nose syndrome by accounting for imperfect detection and misclassification error	May 2025	Management decisions for emerging infectious diseases, endangered species, and invasive species depend on the true state of the system and must be made quickly to maximize opportunities for mitigation. However, molecular detection methods, like any diagnostic test used in the detection of pathogens, may occasionally yield false negatives (i.e., when a sample appears negative but is truly positive) as well as ‘ambiguous,’ ‘uncertain,’ or ‘equivocal’ results (i.e., an inability to confidently classify a sample as negative or positive). Here, we will construct a hierarchical Bayesian model to account for imperfect pathogen detection and ambiguity in the white nose syndrome (WNS) system; our model will use surveillance data to improve forecasts of the invasion front, improve state-dependent decision making, and improve our ability to identify high priority areas for WNS surveillance. We foresee our model also improving the management and decision-making process of other pressing issues which benefit from early detection but are challenged by imperfect and ambiguous detections, including those related to invasive species, endangered species, and pathogen surveillance.

Difficult disease decisions: how to reduce risk when dealing with multiple competing objectives and opposing risk tolerances	May 2026	Ecosystem resource management becomes complicated quickly when managers have multiple objectives and different risk tolerances to a given management action. For example, when faced with the potential threat of disease emergence, resource managers must balance: (a) the risk of a disease outbreak if delaying management, which may result in animal mass mortality at some unspecified point in time, and (b) the risk of implementing unnecessary management if no disease outbreak occurs, which may require tradeoffs in the near-term (e.g., preemptive culling reduces the immediate population size). Using the high-profile emerging pathogen of amphibians, <i>Batrachochytrium salamandrivorans </i>(Bsal), that threatens invasion into North America, we will identify approaches to improve decision-making in the face of multiple objectives and opposing risk tolerances. This work builds on ongoing work; we have already framed the decision related to a possible <i>Bsal</i> invasion with three National Wildlife Refuge managers in the northeastern United States (a hotspot for <i>Bsal</i> risk). We will use simulations, modeling, and optimization techniques to identify optimal actions when there are multiple objectives and opposing risks. We will generate user-friendly visualization tools intended to support risk reduction. We anticipate that our approach and framework can be modified and used for future decisions on human well-being and society related to emerging infectious diseases (and other hazards). Therefore, we foresee that our approach and framework will help better understand, predict, and communicate the tradeoffs decision-makers are forced to make in the face of uncertainty.

Evaluating the impact of management and stressors on at-risk species in Pine Barrens	September 2025	Mandated by the Sikes Act of 1960, natural resource managers work to manage the habitats and wildlife that are found on military installations in the United States and Territories. At Camp Edwards Military Training Reservation (hereby abbreviated to Camp Edwards), Bourne, MA, such wildlife includes the state-protected eastern box turtle (<i>Terrapene carolina carolina</i>) and the declining prairie warbler (<i>Setophaga discolor</i>), which both occupy pine barrens. Therefore, we conducted a two-part project related to both of the preceding species listed.<br><br>In 2020, natural resource managers at Camp Edwards noticed that eastern box turtles were being infected by myiasis, where parasitic flesh flies larviposit into the living tissue of a host. The hypothesized parasite was <i>Dexosarcophaga cistudinis </i>(Aldrich); but its impacts on the host’s body condition, movement, and habitat use are unknown. Therefore, our objectives were to genetically identify the parasite at Camp Edwards, and to compare the body condition, movement, and habitat characteristics of myiasis infected and noninfected eastern box turtles. We radio-tracked 48 turtles weekly from May to August 2022 at Camp Edwards. Upon capture, we recorded turtle infection status, mass, carapace length, shell surface temperature, GPS location, and capture location habitat characteristics. We identified <i>D. cistudinis</i> as the parasite, but we did not find an effect of myiasis on body condition, habitat use, or average daily distance moved. However, myiasis infected turtles had a significantly higher shell temperature (27.92 ± 5.28 °C) than noninfected turtles (26.77 ± 5.64 °C). Collectively, our results suggest that infected turtles may exhibit behavioral fever in response to myiasis, but there was no observed change in body condition or habitat use during a single field season.<br><br>Next, we investigate prairie warblers, and although prairie warblers are declining throughout their range, prairie warbler abundance has increased at Camp Edwards from 2013 – 2022, where point count estimates show a positive trend. During this same time period, there was increased forest thinning and prescribed fire activities at Camp Edwards. Therefore, to investigate habitat management effects on prairie warbler populations, we used a long-term monitoring dataset from 2013-2022. Using a dynamic occupancy model, we estimated colonization, extinction, and detection probabilities. Colonization probability significantly decreased for 25 years since disturbance (YSD). Latitude and longitude significantly affected colonization probability because of where management projects are concentrated. Extinction probability significantly decreased as YSD increased, presumably because fewer occupied sites in older forests could ‘become extinct.’ Observation year significantly affected detection probability. Our results inform how prairie warblers respond to long-term management. Continued habitat management could improve colonization rates and sustain prairie warbler populations.	Eastern box turtles (<i>Terrapene carolina carolina</i>) are listed under the Massachusetts Endangered Species Act as a species of special concern. This species occurs in Pine Barren habitats, where many other species are listed as species of special concern at the state and federal levels. We are currently developing a research study to assess the population dynamics of the eastern box turtle at Joint Base Cape Cod. We aim to explore the effects of a parasitic fly larva on box turtle home range, survival, dispersal, and habitat selection. We will collect radio telemetry data during the summer of 2022, and we will monitor their behavior and/or distribution in comparison to records kept prior to prescribed fire implementation and parasitic larval infestation. The results of this study will be used to inform the upcoming federal listing decisions of species that inhabit Pine barrens habitats by the USFWS.<br><br>We also aim to evaluate the effect of management action on Prairie Warbler occupancy across Camp Edwards.
Closing the loop: characterizing habitat requirements, movements, and life stage linkages of river herring in Massachusetts watersheds	August 2025	In this study, we aim to “close the loop” in our understanding of river herring life stages and limits to productivity by collecting novel data on juvenile river herring density, growth, and survival in estuaries and information on river herring emigrating from lakes. Specifically, our objectives are to: 1)characterize density, growth, and mortality of juvenile river herring in estuaries and upstream lakes, 2) assess age, size, and timing of juvenile river herring during emigration from freshwater to estuarine habitats, and 3) evaluate relationships between spawning adults, juvenile abundance and timing of movements to identify conditions that promote growth and survival. We hypothesize that the timing of juvenile emigration from lakes, size at emigration, and growth in lakes and estuaries will vary among systems and will depend on river herring densities, habitat characteristics, and food resources. The new data collected will be incorporated into a full life-cycle model developed by our collaborators at MADMF to inform the run dynamics and migration timing that leads to the best growth and maintenance of densities, and to inform our work linking life-stages in collaboration with project partners and a population model produced as part of that work. Modeling of factors controlling juvenile size and number during egress, combined with estimates of estuarine-marine survival and growth, will help close current gaps in knowledge of the river herring life cycle and allow for improved understanding of stock-recruitment relationships and population modeling efforts.	River herring (alewife and blueback herring) undergo complex movements between oceanic, estuarine, and freshwater habitats for spawning and rearing of juveniles. Estuaries are likely critical habitats for growth particularly where upstream freshwater habitat is limited; however, no research has sampled juveniles across the freshwater to marine transition to understand the relative contributions to production in different habitats. The proposed project adds to ongoing efforts focused on assessing factors impacting freshwater productivity, monitoring of out-migrants and preliminary estuarine sampling to close the loop in our understanding of factors controlling growth and survival during emigration across the two river herring species. We will partner with other universities (Woods Hole Oceanographic Institution, University of Connecticut), state agencies (Massachusetts Division of Marine Fisheries), federal agencies (US Fish and Wildlife Service, NOAA Northeast Fisheries Science Center), non-profit organizations (Mystic River Watershed Association, River Herring Network, The Nature Conservancy), and the Atlantic States Marine Fisheries Commission to engage citizen scientists in emigration data collection and disseminate information to scientific, public, and policy outlets. The research will lead to improved understanding of stock-recruitment relationships and population modeling efforts toward improving management of river herring.
Impacts of winter lake drawdowns on downstream flows and stream ecosystems	June 2022	Winter lake drawdowns, whereby lakes are drawn down in fall and refilled in spring, are a common lake management tool in Massachusetts. Over the last 6 years, the MA Coop Unit has studied the impacts of drawdowns on lake littoral communities. Not only do winter lake drawdowns impact the hydrology of the lake, but they also cause unintended hydrologic alteration of downstream ecosystems. For example, in the fall during lake water level reductions, water releases cause higher flows than normal. In the spring during refill, flows are greatly reduced during a season when flows are normally the highest. There are general guidelines for drawdowns that include timing of drawdown, limiting maximum flows downstream during drawdown, and maintaining minimum flows downstream during refill; however, it is unknown the extent to which these guidelines are followed, and whether they protect downstream habitats and biota. <br><br>This project will build off preliminary work conducted by MassWildlife, the Massachusetts Division of Ecological Restoration (MDER), the Housatonic Valley Association, and the USGS MA Coop Unit downstream of Onota lake in Pittsfield, MA where we observed improved macroinvertebrate assemblages following restoration of flows in Peck’s Brook. MDER has identified priority sites for streamflow restoration downstream of winter drawdown lakes and conducted flow monitoring using time-lapse cameras in 2018. We will also use lake hydrology data from 18 drawdown and 3 non-drawdown lakes in Massachusetts to guide site selection. For this project, we will monitor hydrology, habitat, temperature, and biotic assemblages in streams to assess ecological responses to winter drawdowns.	Reservoir water-level management in lakes not only influences lake ecosystems, but also downstream ecosystems. Winter drawdowns result in higher stream flows in fall during drawdown and lower stream flows in spring during refill, relative to lakes not managed for drawdown; however, the impacts of this management on downstream ecosystems are unknown. Quantifying the the hydrologic alterations and associated impacts to habitat and biota are critical for developing management strategies. This project is a collaboration between the Massachusetts Division of Fisheries and Wildlife, the Massachusetts Division of Ecological Restoration, and the MA Coop Unit. Ultimately, the hope is that information on downstream effects, in combination with our prior research on in-lake effects, can be used to set recommendations for lake water-level management that can meet human needs while minimizing impacts to ecosystems.
Environmental factors controlling juvenile river herring productivity and emigration	May 2023	This project expands on recent research on juvenile river herring productivity conducted at the University of Massachusetts Amherst (UMass) by using a combination of lab experiments, field assessments, and analysis of spatial and temporal datasets to assess environmental factors limiting juvenile productivity. The results will provide an understanding the effects of abiotic and biotic factors on juvenile river herring growth, survival, physiology, and emigration rates, which are essential for improving estimates of productivity and developing strategies for conservation and restoration in response to climate change, habitat alterations and other environmental challenges to river herring populations.<br><br>The overall goal of this project is to conduct research to fill critical information gaps about juvenile river herring productivity and emigration. We will achieve this through two major objectives:<br><br>Objective 1. Evaluate limits to juvenile river herring productivity<br>a. Conduct lab experiments to test the impact of temperature, food availability, and turbidity on survival, growth, swimming performance, and seawater tolerance of blueback herring<br>b. Compare blueback herring growth in field enclosures with different environmental conditions<br>c. Assess abiotic and biotic factors associated with river herring productivity (density, growth, mortality) among lakes and rivers in the northeast<br><br>Objective 2. Assess factors influencing juvenile river herring emigration rates and timing<br>a. Assess timing and rates of juvenile emigration in lake and river systems<br>b. Compare biotic characteristics (e.g., size, age, growth rates) of emigrating and non-emigrating juveniles to assess factors influencing emigration timing<br>c. Perform analyses to understand how emigration rates influence juvenile densities in lakes, and thus how productivity estimates are affected by emigration events.	River herring [collectively alewife (Alosa pseudoharengus) and blueback herring (Alosa aestivalis)] have been valued by human societies since pre-colonial times, but populations have undergone a dramatic coast-wide decline over the past five decades. Information on factors influencing freshwater productivity of juvenile river herring, emigration timing, and early seawater survival are needed to understand, predict, and mitigate population declines. This project is a collaboration between the U.S. Geological Survey (Conte Anadromous Fish Lab and Massachusetts Coop Unit), the University of Massachusetts Amherst, the U.S. Fish and Wildlife Service, Woods Hole Oceanographic Institution, Connecticut Department of Energy and Environmental Protection, and the Massachusetts Division of Marine Fisheries. Results of this research will be used to inform population models for river herring stock assessment and decisions related to federal listing of river herring under the Endangered Species Act and management decisions toward restoring river herring in the northeast.
Assessing attitudes and impacts to society associated with the use of nontoxic ammunition for hunting on National Wildlife Refuges	December 2019	Despite extensive scientific evidence of the detrimental effect of spent lead ammunition on wildlife and potential for human exposure, reducing the use of lead-based ammunition for hunting activities can be a controversial and contentious issue. Through the implementation of mail-back surveys and group interviews, this project aims to understand hunters’ perceptions towards a voluntary transition to non-lead ammunition use for hunting white-tailed deer (Odocoileus virginianus) on targeted National Wildlife Refuges in the Northeast U.S. Specifically, this project aims to identify the practical barriers associated with a voluntary transition to non-lead ammunition use and what factors would influence hunters to switch. Assessment of the practical barriers to transitioning to non-lead ammunition will allow the National Wildlife Refuge System to direct targeted outreach and education strategies to achieve behavioral change in hunter ammunition choice.	Since the 1960s, the recognition of the negative effect of lead on humans and wildlife has resulted in regulations to reduce both human exposure and the amount of lead introduced into the environment. Federal restrictions on lead-based ammunition for waterfowl hunting were implemented in 1991. Since then restrictions on lead-based ammunition use have expanded in some states, however, lead is still a primary component of ammunition used for non-waterfowl hunting in the U.S. The continued use of lead-based ammunition for hunting white-tailed deer (Odocoileus virginianus), in particular, facilitates completed pathways to lead exposure for hunters, their family members, and for non-target species that scavenge the gut piles and carcasses of deer left in the field. Voluntary approaches to reducing lead-based ammunition use have been shown to garner increased support from hunters and have been recognized as a viable option for mitigating the impacts of lead from hunting activities. In collaboration with the University of Massachusetts-Amherst, USGS, and the USFWS, we have conducted mail-back surveys and group interviews with hunters at targeted National Wildlife Refuges in the Northeast U.S. This project aims to identify the practical barriers associated with a voluntary transition to non-lead as perceived by hunters, and what factors would influence hunters to switch to non-lead alternatives. Identifying the barriers and influences to non-lead use will help the National Wildlife Refuge System direct more targeted outreach and education strategies in order to better achieve behavioral change in regard to hunter ammunition choice.
Natural-Ecological and Socio-Political Factors Influencing Urban Forest Management in Massachusetts	December 2019	From wildlife habitat, to carbon sequestration, urban forests supply an array of ecosystem benefits to over 90% of Massachusetts’ residents, who live and work in an urban setting. Urban trees, however, face a multitude of challenges from limited growing space, to invasive pests. To gain further understanding into emergent urban forest management issues, we conducted 50 qualitative research interviews with municipal tree wardens, from 2014-2016. Forest health emerged as an important theme, as interviewees (n=49) indicated that they routinely monitor for pests of urban trees. A significant number of interviewees (n=13) also indicated that they interact with urban tree committees. We will explore the potential for planting low-maintenance conifers, like Chinese hemlock, as part of an overarching urban forest health management and diversification strategy that incorporates host plant resistant species. We will also explore the characteristics and needs of urban tree committee volunteers.	With estimated losses of 36 million trees per year, urban tree canopy (UTC) cover continues a downward trend, nationwide. UTC cover losses are believed to result from a variety of factors including development, maintenance practices, and pests. Conservative estimates of national UTC cover benefits equate to $100 million per year, relative to carbon sequestration, pollution removal, reduced energy and reduced power plant emissions. These, and other ecosystem services, are enjoyed by large numbers of citizens living and working in urban settings, including an estimated 90% of Massachusetts’ residents. To gain further understanding into emergent urban forest management issues in Massachusetts, we conducted qualitative research interviews with community-based urban forestry decision-makers, known as municipal tree wardens. This project involves collaboration between the US Forest Service, US Geological Survey, MA Department of Conservation and Recreation, University of Massachusetts Center for Agriculture Food and the Environment, and the UMass Department of Environmental Conservation. Interviewees indicated they routinely interact with volunteer organizations, including urban tree committees, and routinely monitor for pests of urban trees. Results will inform further UMass urban forestry integrated research and extension initiatives.
The Ecological Value of Spruce Plantations in Massachusetts	December 2019	The planting of exotic Norway spruce plantations to supplement native forest stock has been common practice throughout the north-eastern United states over the past century. These plantations, however, were frequently created without much consideration to the effect they would impose on local wildlife diversity. Recent shifts in conservation priorities towards increasing and supporting biodiversity have raised new questions to the role exotic plantations will have moving forward. More specifically, it is widely unknown if the habitat provided by plantations can support an adequate level of biodiversity. This study aims to examine the comparative ecological value of spruce plantations to surrounding native forest stands in Massachusetts, using birds as indicators of biodiversity. In addition to using avian occupancy and abundance, we will weight relative species values by incorporating Partners in Flight Conservation scores to provide a more objective estimate of overall ecological importance. This project is being conducted in partnership between the University of Massachusetts Amherst, USGS Massachusetts Cooperative Research Unit, Massachusetts Department of Conservation and Recreation, and U. S. Forest Service. Through this research, we hope to better inform land managers on how Norway spruce plantations are contributing to their conservation goals.

Assessing Hunter Values, Expectations, and Satisfaction Regarding Controlled White-Tailed Deer Hunts in Suburban Eastern Massachusetts	December 2019	White-tailed deer (Odocoileus virginianus) are particularly abundant in portions of eastern Massachusetts where high densities have resulted in ecological degradation from over-browsing as well as increased human-deer conflicts. These negative impacts necessitate the importance of addressing deer overabundance. Regulated hunting is a widely accepted deer management strategy used to effectively reduce and maintain deer densities, although its use in suburban landscapes may be challenged by the limited long-term participation of hunters. Presumably, continued hunter participation is driven largely by participants’ satisfaction with their hunting experience and highly controlled hunts in suburbia may restrict participants in ways that minimize satisfaction. Without a dependable suburban hunting constituency, successful reduction of deer populations will be challenging. A better understanding of suburban hunters’ expectations, preferences, and limitations is of great importance if effective deer management programs are to be implemented. Our research effort is a collaboration between the Massachusetts Division of Fisheries and Wildlife and the U.S. Geological Survey Massachusetts Cooperative Fish and Wildlife Research Unit at the University of Massachusetts, Amherst. Results of this study will give wildlife managers more insight when guiding communities through the development of management programs that focus on recruiting and retaining devoted hunters willing to considerably lower deer densities over time.	White-tailed deer (Odocoileus virginianus) are abundant throughout Massachusetts, particularly in eastern portions of the state where suburban landscapes provide high quality habitat. Ecological degradation from over-browsing and increased human-deer conflicts result in a need to address overabundant deer populations. Regulated hunting is a widely accepted deer management strategy used to effectively reduce and maintain deer densities, although its use in suburban landscapes presents challenges. Of particular concern is the long-term participation of devoted hunters. Presumably, continued hunter participation is driven largely by participants’ satisfaction with their hunting experience. Highly controlled hunts may restrict participants in ways that minimize satisfaction. Without a dependable suburban hunting constituency, successful reduction of deer populations may be impeded. A better understanding of suburban hunters’ expectations, preferences, and limitations is of great importance if effective deer management programs are to be implemented. This research effort is a collaboration between the Massachusetts Division of Fisheries and Wildlife and the U.S. Geological Survey Massachusetts Cooperative Fish and Wildlife Research Unit at the University of Massachusetts, Amherst. Results of this study will assist wildlife managers in better understanding what motivates hunters to participate in controlled deer hunts so that communities may be guided through developing more successful, lasting deer management programs. If community members, town representatives, and state wildlife authorities communicate clearly to make realistic, science-based decisions, effective suburban deer management programs using regulated hunting may be attainable in eastern Massachusetts.
Estimating Black Bear Density, Abundance, and Source-Sink Dynamics in Massachusetts	June 2022	In the 1970s, black bears (Ursus americanus) existed as a small and isolated population in the Berkshire Mountains of Massachusetts. Since then, the black bear population has grown in number and expanded eastward across the state. However, current black bear density estimates in different parts of the state are lacking, as are population estimates. This information is required for informed and successful management of this important game species across the state. We are conducting a capture-recapture survey for black bears using hair snares and molecular techniques to estimate density and abundance and understand how density and abundance changes with different land cover types and levels of human influence. We are also quantifying black bear population sources and sinks to determine areas of population growth and decline. Massachusetts Division of Fisheries and Wildlife, Amherst College, and Massachusetts Department of Conservation and Recreation are project collaborators. Results from this research will provide information on black bear population dynamics and allow us to estimate the population size of bears across the state. This information will be used in developing a comprehensive management plan for black bears in Massachusetts.

Modeling Black Bear Habitat Use, Movement, and Connectivity in Massachusetts	December 2019	The black bear (Ursus americanus) population in Massachusetts has been growing in number and expanding into human dominated areas due to conservative management and increasing availability of human food resources. Quantifying seasonal black bear habitat use and movement in relation to land cover in natural and human-dominated areas is necessary for understanding black bear behavior and creating effective black bear management programs. Estimates of connectivity are also required to identify important movement corridors, direct wildlife-road mitigation efforts, and predict black bear movements into currently unoccupied areas of the state. Our analyses are based on GPS telemetry collar data from over 47 bears that has been collected since 2009 by our Massachusetts Division of Fisheries and Wildlife collaborators. Other collaborators on the project include the Massachusetts Department of Transportation and Massachusetts Department of Conservation and Recreation. Results will be used to inform management of bears and bear habitat in both natural and human-dominated areas of the state.

Massachusetts Residents' Attitudes Toward Black Bears and Black Bear Management	December 2019	The black bear (Ursus americanus) population in Massachusetts is growing in size and expanding in range, and bears are becoming increasingly more common in suburban areas of the state. As the Massachusetts’ black bear population increases and expands, it continues to push into areas where the general public is largely inexperienced with bears. A statewide survey, conducted in collaboration with Massachusetts Division of Fisheries and Wildlife (MassWildlife) and Responsive Management, Inc., will be used to assess Massachusetts residents' attitudes toward black bear and black bear management. Results of this study will provide a more detailed understanding of Massachusetts’ residents’ opinions on the bear population, experience with bears, and opinions on black bear management options. These results will be used by MassWildilfe to make informed management decisions regarding black bears and will help MassWildlife gain a better understanding of the current challenges facing black bear management in the third most densely populated state in the country.

Dwarf Wedgemussel Propagation and Restoration in the Mid-Atlantic and Northeastern US	May 2022	The dwarf wedgemussel (DWM), Alasmidonta heterodon, is a small, freshwater mussel historically known from at least 15 Atlantic slope drainages from New Brunswick, Canada to North Carolina; however, population declines throughout its range resulted in Federal listing of the species in 1990. The decline of DWM in areas previously thought to have the most viable and largest populations leads to significant concerns about the long-term viability of the species. <br><br>The overall goal of this project is to conduct research to inform and guide recovery of DWM through propagation and reintroduction. This project builds upon recent US Fish & Wildlife Service efforts to evaluate DWM habitat and establish a propagation facility for imperiled mussel populations. There are 3 objectives:<br>1) Develop propagation and culture techniques that optimize survival, growth, and production of mussels at the Cronin Aquatic Resource Center<br>2) Assess potential locations for restoring DWM populations based on mussel densities, population genetics, host fish densities, and mussel habitat and water quality requirements <br>3) Evaluate genetic structure of DWM populations and management actions for restoring DWM to preserve genetic diversity<br>These data will be used to identify management units, develop broodstock genetic guidelines, develop criteria and a decision tree to select ideal locations for reintroduction and augmentation, and ultimately inform recovery and management decisions of this species.	The dwarf wedgemussel (DWM), Alasmidonta heterodon, is a small, freshwater mussel historically known from at least 15 Atlantic slope drainages from New Brunswick, Canada to North Carolina; however, population declines throughout its range resulted in Federal listing of the species in 1990. The decline of DWM in areas previously thought to have the most viable and largest populations leads to significant concerns about the long-term viability of the species. This project is a collaboration between the U.S. Geological Survey's (USGS) Massachusetts Cooperative Fish and Wildlife Research Unit, the USGS Leetown Science Center, and the U.S. Fish & Wildlife Service. We will develop in vitro propagation techniques, conduct laboratory experiments to assess different culture methods, compile data on DWM populations and habitat requirements, collect and synthesize data on host fish populations, and assess population genetics. These data will be used to identify management units, develop broodstock genetic guidelines, develop criteria and a decision tree to select ideal locations for reintroduction and augmentation, and ultimately inform recovery and management decisions of this species.
Restoring Aquatic Habitats through Dam Removal	June 2023	There are thousands of small dams in Massachusetts that fragment and impair nearly every stream and river throughout the state, altering fish passage, flow, sediment, and nutrient movement, and making these ecosystems less resilient to natural and anthropogenic disturbances. To date, nearly 60 dams have been removed in the state, yet only a fraction of these streams have been monitored to assess water quality, habitat, and biotic responses to dam removal. Information on the benefits of dam removal, including the watershed and long-term impacts of these changes, are critical for the public to understand expectations following dam removal and to gain support for future dam removals. We also need a better understanding of ecological changes following dam removal in order to better answer questions from local, regional, and national regulatory community that impact our ability to advance projects. Over the last three years, extensive pre-removal data has been collected on temperature, dissolved oxygen, and macroinvertebrates at 12 dam removal sites across Massachusetts through a partnership with researchers at the University of Massachusetts (UMass) and the Massachusetts Division of Ecological Restoration (MDER). These data showed that most sites had significant warming downstream of dams, highlighting the potential for extensive consequences of dams on biota, particularly coldwater fishes. However, the magnitude and extent of effects of dams are highly variable across sites and raise additional questions. Here, we propose to continue sampling these 12 sites plus 3 additional coldwater streams to quantify water quality, macroinvertebrate, and fish responses to dam removal. We will use the extensive fish database for Massachusetts and collaborate with UMass, MDER, and the Massachusetts Division of Fisheries and Wildlife (MassWildlife) to add additional sites for a broader assessment of fish responses. The results will be used to model the collective ecological benefits of dam removal statewide and will be synthesized into outreach materials highlighting these benefits to promote future dam removal toward increasing the quality and resilience of stream ecosystems.

Yellow Lampmussel Restoration Initiative	January 2020	The Yellow Lampmussel (Lampsilis cariosa; YLM) is a freshwater mussel (Unionoida) with a restricted range in Massachusetts. The species is currently only known to exist in the Connecticut River mainstem and lower sections of a few major tributaries, with one historic record from the Merrimack River. The species is protected as Endangered under the Massachusetts Endangered Species Act (MESA), and prior to 2006, was thought to be extirpated from the Commonwealth. Increased surveys from 2005 through 2014 suggest that the Massachusetts population is widespread, with patches of individuals in the Connecticut River from the Connecticut state line upstream to Hadley, MA. Threats to the YLM in the Connecticut River are not fully understood, but are likely associated with hydrologic alteration and sediment distribution. Historic and current point and non-point sources of pollution may also affect the distribution and viability of these populations.<br><br>Like other native freshwater mussels, the YLM’s lifecycle includes a parasitic larval stage (glochidia), which must attach to and mature on a fish host. Yellow Lampmussels have been observed to use Striped Bass, White Perch, Yellow Perch, and Smallmouth Bass as hosts throughout their range. However, host fishes for the Massachusetts populations may be unique, and identification of region-specific host fishes may guide conservation efforts through fishery management. Laboratory propagation of freshwater mussels has also been identified in the Massachusetts State Wildlife Action Plan as a potential conservation measure to reintroduce mussels to historically occupied sites, or to augment populations that are currently present. The Richard Cronin Aquatic Resource Center in Sunderland, MA began research to propagate freshwater mussels in 2015, making it the first mussel propagation facility in New England.<br><br>The project aims to conduct research to inform conservation of YLM through investigations of early life history and ecology. Specifically, USFWS and UMass will:<br>1. Culture YLM juveniles using proven methods.<br>2. Investigate methods to increase growth and survival of juvenile YLM.<br>Research on Eastern Lampmussel (L. radiata), a surrogate species with similar characteristics to YLM, may be used to address the second objective in the event YLM juveniles are not available in research quantities.	In North America 72% of freshwater mussel species are endangered, threatened, or of special concern due to factors such as habitat loss and degradation, biological invasion, and land use change. Propagation of freshwater mussels has been considered a necessary conservation strategy for population restoration where threats have been mitigated but small population sizes limit population viability. Developing and refining culture methods for target mussel species is a critical step toward population restoration. This project is a collaboration between the U.S. Fish and Wildlife Service, Massachusetts Division of Fisheries and Wildlife, and the Massachusetts Cooperative Fish and Wildlife Research Unit. Our results on the effects of probiotic supplements and secondary rearing designs are critical for developing effective culture methods for the state-listed yellow lampmussel (Lampsilis cariosa), and will more broadly add to the limited literature on probiotic use and secondary rearing designs in freshwater mussel culture.
Development of a Rapid Assessment Protocol for Aquatic Passability of Tidally Influenced Road-Stream Crossings	September 2017	As part of a project funded by the North Atlantic LCC, a unified protocol has been developed for the rapid assessment of stream crossings focusing on aquatic connectivity. This protocol and an effort to coordinate and support crossings assessments throughout the region was launched in June 2015 as the North Atlantic Aquatic Connectivity Collaborative (NAACC). The protocol developed for the NAACC is for non-tidal streams and rivers. It is not suitable for tidal crossings because it does not account for the bi-directional flow and daily variations in depth and velocity that are typical of tidal streams. Aquatic organism passage through road-stream crossings on tidal streams is of critical importance not only for fish and other organisms that live in coastal marshes and estuaries, but also for diadromous fish that must pass through the tidal portions of streams to reach important habitat further upstream. We propose to begin development of a rapid assessment field protocol for the assessment of aquatic organism passage at road-stream crossings on tidal streams that can be integrated into the larger NAACC initiative. This first phase of the process will focus on assembling information on the organisms and issues that should be addressed by such a protocol, the convening of an expert technical advisory committee to provide input and critical review of the materials developed as part of the project, and development of a draft field assessment protocol and scoring system for road-stream crossings on tidal streams.

Interannual Variation in Juvenile River Herring Productivity and Responses to Dam Removal	August 2025	Inter-annual variation in river herring densities presents challenges to understanding the effects of restoration on fish productivity. Many agencies are actively working to improve aquatic connectivity in coastal rivers, with the specific aim of restoring diadromous fish populations, including river herring. There are several recent and future dam removals in eastern Massachusetts that will likely benefit river herring, but there is currently no planned monitoring of freshwater productivity following dam removal. We propose to sample juvenile river herring in freshwater lakes for at least 5 years after dam removal to assess patterns of river herring recovery, while simultaneously sampling lakes with current natural runs to address the following questions:<br>(1)How do juvenile river herring densities and growth vary among years and in relation to lake specific and regional environmental conditions?<br>(2)How many years following dam removal does it take to restore juvenile river herring productivity to that of a natural run?<br>We will also continue to stock two lakes with river herring, where we know the exact number of adults entering the systems, to develop relationships between adult density and juvenile density and growth, and can control stock densities under different environmental conditions. These stocked lakes also provide opportunities to develop pedigrees and understand factors influencing reproductive success.	River herring have been valued by human societies from the pre-colonization period onwards, but are at historical low abundance and at risk of continued declines given continued anthropogenic stressors, including climate change. River herring densities vary widely across New England watersheds, and the numbers and timing of river herring migrations also vary greatly from year to year. Several (>5) years of data is needed to begin to evaluate patterns of adult and juvenile densities among years, particularly given the delay between juvenile outmigration and their return to spawn 3-4 years later. Our results will show how densities and growth of juvenile river herring vary among years in relation to environmental conditions and will also document changes in river herring productivity following dam removal. This research is a collaboration between the USGS, University of Massachusetts Amherst, Massachusetts Division of Marine Fisheries, and The Nature Conservancy. Knowledge of the link between run counts and juvenile productivity are critical to update population models, and information about year-to-year variability can help to describe uncertainty around population estimates, ultimately informing river herring management decisions. Data from dam removal sites will provide valuable new insights about annual changes in river herring densities with novel access, and can be used to develop expectations for future aquatic connectivity restoration projects.
Brook Floater Research and Conservation	October 2021	The Brook Floater (Alasmidonta varicosa) is a stream-dwelling freshwater mussel native to the Atlantic Slope of the United States and Canada that has experienced large population declines over the last 50 years and is at high risk of extinction. The species’ distribution has been restricted to approximately 50% of its historic sites, is listed as Threatened or Endangered by most states where it occurs, and has been petitioned for listing under the federal Endangered Species Act. Five states within the region were awarded a competitive State Wildlife Grant (SWG) to increase range-wide cooperative conservation efforts and strategic planning towards reducing further population losses, and defining approaches for recovery of A. varicosa. This project will focus on strategies for achieving conservation through multiple objectives: (1) Project partners will build upon findings from a recently completed range-wide status assessment. (2) Partners will develop a conservation working group that will help to develop initiate standardized surveys that will be conducted throughout partnering states to estimate abundances and predict occupancy of Brook Floater and associated SGCN mussels. (3) We will utilize Structured Decision Making approaches to focus monitoring design and conservation planning objectives at the state and regional scale. (4) We will coordinate the development of propagation methods and approaches for population restoration. (5) We will identify additional site-specific conservation actions to benefit A. varicosa and associated SGCN habitat.

Population augmentation and reintroduction have been identified as critical components of a recovery plan, and our research will develop methods to propagate Brook Floater. This research is a collaboration between Massachusetts Division of Fisheries and Wildlife, U.S. Fish & Wildlife Service, U.S. Geological Survey, and the Connecticut River Conservancy, with additional collaboration from several state agencies along the east coast from Maine to Georgia, mussel biologists, and consultants. We will develop and implement a rapid assessment protocol and a long-term monitoring protocol that will be used throughout the range of Brook Floater to create comparable datasets and develop a species distribution model. The research also includes citizen science involvement in mussel and habitat surveys and numerous restoration and outreach efforts.
Using Genomics to Understand Population Dynamics and Enhance the Management of Canada Lynx Populations in the Contiguous United States	December 2019	Management of Canada lynx (Lynx canadensis) populations occurring at the edge of the species range has been informed by limited regional studies mostly focused on demographics and ecology. Tools are needed to provide baseline metrics of population health and an understanding of landscape dynamics to inform regional and range-wide management and monitoring strategies. Next-generation sequencing produces a high density of genetic markers (e.g., single nucleotide polymorphisms, structural variants, mutations) that enhance the precision and reliability of population demographic parameter estimates relevant to conservation practitioners. In September of 2018 we produced the first-ever reference genome for Canada lynx, which will serve as a publicly available community resource and a powerful tool for population-level assessments. Ultimately this work will provide baseline metrics for managing Canada lynx populations in the lower 48 states and management recommendations that conserve or enhance population fitness and resiliency. This project is a multi-disciplinary collaboration including the Massachusetts Cooperative Fish & Wildlife Research Unit at UMass Amherst, the Vertebrate Genomes Laboratory at Rockefeller University, the State of Maine Department of Inland Fisheries & Wildlife, and the Smithsonian Institution.

Comparative Ecology and Conservation of Bears in North and South America	December 2020	The spectacled bear (Tremarctos ornatus) and American black bear (Ursus americanus) are considered to be representative landscape species, meaning that large scale conservation benefits can result from conservation efforts for these species and the areas they inhabit. However, the general lack of information about spectacled bears, particularly their distribution in Peru, makes it difficult to develop conservation plans. This research aims to create a spectacled bear distribution model and verify the species' presence in areas without current records in order to obtain reliable distribution predictability. In contrast, distribution, ecology, and management strategies for the American black bear are well known, and can serve to inform the same topics for the somewhat similar spectacled bear, for which relatively little is known. Results will contribute to the national plan for the conservation of spectacled bears being implemented by our major collaborator, the Peruvian forest and wildlife service (Servicio Nacional Forestal y de Fauna Silvestre - SERFOR), and allow a comparative study among these two bear species.

Effects of Dam Removal on Stream Ecosystems	January 2018	Concerns about safety and interests in restoring stream connectivity have increased dam removal in the last two decades. This research investigates the effects of dam removal on stream ecosystems. We will quantify dissolved oxygen and temperature upstream, within, and downstream of impoundments at 12 sites in MA. Eight of the sites are slated for dam removal in 2015 and 2016, and we will quantify the effects of removal on dissolved oxygen, temperature, and other aspects of the stream ecosystem. Data will be useful in understanding the extent to which dams impair stream ecosystems and quantifying potential improvements in water quality following dam removal. Potential improvements can be used to leverage support for dam removal and help to prioritize dam removals that will maximize ecological benefits.	Dams are highly pervasive features of the American landscape, and are especially prevalent in New England, the region with the highest density of dams in the United States. Dams have numerous impacts on stream ecosystems; however, the extent of impacts are likely to vary based on dam characteristics and the surrounding landscape. This research documents the variability of impacts to dissolved oxygen and temperature and will quantify factors explaining variation in response. Understanding factors influencing the extent of dam impacts on water quality can help to predict impacts of dams and dam removal on aquatic ecosystems . This research is a collaboration between the USGS, the Massachusetts Division of Ecological Restoration, and the USFS. Ultimately, a better understanding of impacts of dams can help to prioritize dam removal restoration efforts to maximize ecological benefits.
Feasibility and uses for freshwater mussel culture in Massachusetts	December 2017	Half of Massachusetts native freshwater mussel fauna are listed as Endangered or Special Concern under MESA. Population augmentation and re-introduction programs have been used to restore freshwater mussel populations in other states for more than 20 years, and have reported significant success with some species. We propose to test the feasibility of mussel propagation at the US Fish and Wildlife Service’s Cronin Aquatic Resource Center in Sunderland, MA. Siting of a propagation facility in Massachusetts will increase collaboration with other New England states for the management of regional populations, increase collaboration with academic and Federal partners, and increase competitiveness for funding sources. Ultimately, we hope to develop a successful restoration program in Massachusetts.	None
Evaluating freshwater productivity and sampling approaches for juvenile river herring in freshwater lakes and ponds	December 2017	Anadromous alewife (Alosa pseudoharengus) populations have experienced alarming declines during the last two centuries. Seasonal migration and a unique life history has left them vulnerable to continued anthropogenic effects/events like habitat degradation, bycatch at sea and disrupted access to critical spawning rivers due to dams. Alewife provide vital marine-derived nutrients to freshwater systems, contribute as a prey-base for various piscivorous species and have strong cultural significance among coastal communities. To date, most population assessments are a function of adult run counts as they enter spawning habitats and data associated with freshwater juvenile productivity is lacking. Information gaps exist on the relationship between these adult spawning stocks and recruitment. Reliable abundance estimates hinge on accurate early life history data and remains a challenge. Our research objective is two-fold: evaluate factors influencing freshwater productivity and compare standardized and cost-effective survey-methodology to be applied across systems. A survey of 20 coastal lakes sampled in Massachusetts in 2014 will be expanded geographically to include nursery lakes with known alewife runs in Connecticut, Rhode Island, New Hampshire and Maine. Each lake will be sampled using purse seines and sonar imaging three times throughout the summer of 2015 for alewife young of year. We will assess juvenile densities, age and growth and mortality rates along with environmental predictors of nursery habitat. By testing novel methods of estimating alewife cohort dynamics we will compare/evaluate the legitimacy of these metrics to predict population size. Our results will help inform future population models and provide direction for habitat restoration and management decisions	None
Establishing links between stream flow and ecological integrity in the Sudbury River	February 2015	Streamflow is a primary driver of river and stream ecology. Lotic organisms are adapted to living in flowing water with a characteristic timing, duration, and magnitude of high and low flow events. Alteration of this flow regime as a result of impoundments, water withdrawals, and changes to land use patterns is frequently accompanied by dramatic changes to the biotic assemblages. We investigated effects of flow alteration on stream ecology in the Sudbury River, a river located in a suburban Boston and that has long been exploited for water resources. The Sudbury River has the full complement of flow alterations, including: mainstem impoundments, surface and groundwater withdrawals, and urbanization. Analysis of 33 years of stream gage data indicates that the river is undergoing contemporary hydrologic alteration. These changes include a roughly 200% increase in rise rates of flows, an approximate 65% decrease in 1-day minimum flows, and a trend towards increasing high flow pulse counts. Biotic sampling of macroinvertebrates, mussels, and fishes in summer of 2014 demonstrated that the Sudbury River is now dominated by generalist species. The high proportion of tolerant and moderately tolerant macroinvertebrate taxa within our samples suggests that water quality pollution is a problem in the Sudbury. Of five mussel species sampled, all are generalists in their habitat requirements. Though one mussel species of special concern was sampled, the most abundant species collected were the widespread Eastern elliptio (58%) and Eastern lampmussel (40%). We used the target fish community (TFC) model to assess the degree to which the fish assemblage deviated from that expected for a river with similar zoogeographic and physical features. Overall, the current community has a 22.7% similarity to the TFC. Of the four fluvial specialist species present in the TFC, only fallfish was sampled in our study. The fish assemblage has shifted from one that should be dominated by fluvial specialist and fluvial dependent species to one overwhelmingly dominated by macrohabitat generalists (90.6% of fishes sampled). These shifts in biotic assemblages are consistent with other studies that show shifts in assemblages from fluvial specialists to habitat generalists with hydrologic alteration. If the current trends continue, it is likely that biotic assemblages will experience increasing pressure from hydrologic alteration.	None

Alces 47:53-68. \| Abstract	July 2011	Moose (Alces alces) populations have been re-established in much of the historic range in the northeastern United States. Recently the southern edge of the range has been extended southward into southern New England and northern New York from established populations in northern New England. Moose populations are now well established in Massachusetts and Connecticut, and continue to expand in New York. This southerly range expansion in the Northeast has taken place when moose populations elsewhere along the southern edge of their range are in decline, with climate change being cited as a prominent cause. The forests of New England transition from northern forest types dominated by spruce (Picea spp.), balsam fir (Abies balsamea), beech (Fagus grandifolia), birch (Betula spp.), hemlock (Tsuga canadensis), and maple (Acer spp.), where moose are common, to transitional hardwood forests increasingly dominated by oak (Quercus spp.) and white pine (Pinus strobus), where little is known about moose habitat requirements. The habitat moose have recently occupied in the Northeast is also some of the most densely populated by humans anywhere in moose range, which has raised concerns over human safety and the threat posed by moose-vehicle collisions. In light of these recent developments, we conducted a literature search on moose in the northeastern United States and distributed a questionnaire and conducted phone interviews with biologists responsible for moose management across the region to determine the status of moose in the northeast, what management activities are taking place, and what research is needed to fill the knowledge gaps regarding moose in New England and New York. Moose numbers have stabilized throughout much of the region, with continued population growth in northern New York. Management activities range from regulated harvest of moose in the 3 northern New England states, to no active management in southern New England and New York. In Maine, New Hampshire, and Vermont, >3,000 moose are harvested every fall. Moose-vehicle collisions are a concern across the region, with >1,000 occurring annually, including several human fatalities. Increased information on demographics, specifically the roles that parasitism by winter tick (Dermacentor albipictus) and brain-worm (Parelaphostrongylus tenuis) play in mortality, is greatly desired. In general moose appear to be thriving in the Northeast despite continued concerns with high temperatures and incompatibility with high human populations.

In recent years, there has been substantial interest in developing Regional Monitoring Networks with states and EPA Regional offices to detect long-term climate change–related impacts on aquatic communities in freshwater streams. Current participants, including states in the northeast, mid-Atlantic and southeast, are initiating collection of thermal, hydrologic and biological data from targeted sites in each state. To help further this effort, the U.S. EPA and collaborators have written a guidance document to facilitate more uniform and effective collection of continuous temperature and water depth data at ungaged sites in wadeable streams. This document addresses questions related to equipment needs, configuration, placement, installation techniques, data retrieval, and data processing. The collection of these data will further efforts to detect and track climate change–related impacts over the long term, further our understanding of how biological, thermal, and hydrologic conditions vary spatially and temporally and inter-relate to one another, and help inform state and federal agencies on how to attribute altered environmental conditions to climate change versus other stressors.

Ticks and Tickborne Diseases 15:102342. DOI: 10.1016/j.ttbdis.2024.102342. \| Abstract \| Publisher Website	April 2024	Ixodid (hard) ticks play important ecosystem roles and have significant impacts on animal and human health via tick-borne diseases and physiological stress from parasitism. Tick occurrence, abundance, activity, and key life-history traits are highly influenced by host availability, weather, microclimate, and landscape features. As such, changes in the environment can have profound impacts on ticks, their hosts, and the spread of diseases. Researchers recognize that spatial and temporal factors influence activity and abundance and attempt to account for both by conducting replicate sampling bouts spread over the tick questing period. However, common field methods notoriously underestimate abundance, and it is unclear how (or if) tick studies model the confounding effects of factors influencing activity and abundance. This step is critical as unaccounted variance in detection can lead to biased estimates of occurrence and abundance. We performed a descriptive review to evaluate the extent to which studies account for the detection process while modeling tick data. We also categorized the types of analyses that are commonly used to model tick data. We used hierarchical models (HMs) that account for imperfect detection to analyze simulated and empirical tick data, demonstrating that inference is muddled when detection probability is not accounted for in the modeling process. Our review indicates that only 5 of 412 (1 %) papers explicitly accounted for imperfect detection while modeling ticks. By comparing HMs with the most common approaches used for modeling tick data (e.g., ANOVA), we show that population estimates are biased low for simulated and empirical data when using non-HMs, and that confounding occurs due to not explicitly modeling factors that influenced both detection and abundance. Our review and analysis of simulated and empirical data shows that it is important to account for our ability to detect ticks using field methods with imperfect detection. Not doing so leads to biased estimates of occurrence and abundance which could complicate our understanding of parasite-host relationships and the spread of tick-borne diseases. We highlight the resources available for learning HM approaches and applying them to analyzing tick data.

Proceedings of the 8th International Conference of Novatech. \| Abstract \| Download \| Publisher Website	June 2013	Long-term field studies of the effectiveness and sustainability of decentralized stormwater management are rare. From 2005-2011, we tested an incentive-based approach to citizen participation in stormwater management in the Shepherd Creek, Cincinnati OH USA. Hydrologic, biological, and water quality data were characterized in a baseline monitoring effort 2005-2007. Reverse auctions held successively in 2007 and 2008 engaged citizens to voluntarily bid on stormwater control measures (SCMs); and successful bids led to implementation of SCMs, which led to an enhancement of catchment detention capacity. We tested for attributes of sustainability (co-consideration of social, economic, and environmental (hydrologic, soils, aquatic biology) aspects), and summarize lessons-learned. Our results and outcomes provide a basis for planning future field studies that more fully determine the effectiveness of stormwater management in terms of sustainability.

Wildlife Monographs 210: e1070. https://doi.org/10.1002/wmon.1070 \| Abstract	July 2022	Wildlife population estimators often require formal adjustment for imperfect detection of individuals during surveys. Conventional distance sampling (CDS) and its extensions (mark‐recapture distance sampling [MRDS], temporary emigration distance sampling [TEDS]) are popular approaches for producing unbiased estimators of wildlife abundance. However, despite extensive discussion and development of distance sampling theory in the literature, deciding which of these alternatives is most appropriate for a particular scenario can be confusing. Some of this confusion may stem from an incomplete understanding of how each approach addresses the components of the detection process. Here we describe the proper application of CDS, MRDS, and TEDS approaches and use applied examples to help clarify their differing assumptions with respect to the components of the detection process. To further aid the practitioner, we summarize the differences in a decision tree that can be used to identify cases where a more complex alternative (e.g., MRDS or TEDS) may be appropriate for a given survey application. Although the more complex approaches can account for additional sources of bias, in practical applications one also must consider estimator precision. Therefore, we also review the concept of total estimator error in the context of comparing competing methods for a given application to aid in the selection of the most appropriate distance sampling approach. Finally, we detail how the use of more advanced techniques (i.e., informed priors, open‐population distance sampling models, and integrated modeling approaches) can further reduce total estimator error by leveraging information from existing and ongoing data collection .By synthesizing the existing literature on CDS, MRDS, TEDS and their extensions, in conjunction with the concepts of total estimator error and the components of the detection process, we provide a comprehensive guide that can be used by the practitioner to more efficiently, effectively, and appropriately apply distance sampling in a variety of settings.

Journal of Wildlife Management 86:e22185. https://doi.org/10.1002/jwmg.22185 \| Abstract \| Publisher Website	January 2022	Managers rely on accurate estimators of wildlife abundance and trends for management decisions. Despite the focus of contemporary wildlife science on developing methods to improve inference from wildlife surveys, legacy datasets often rely on index counts that lack information about the detection process. Data integration can be a useful tool for combining index counts with data collected under more rigorous designs (i.e., designs that account for the detection process), but care is required when datasets represent different population processes or are mismatched in space and time. This can be particularly problematic in cases where animals aggregate in response to a spatially or temporally limited resource because individuals may temporarily immigrate from outside the study area and be included in the abundance index. Abundance indices based on brown bear (<i>Ursus arctos</i>) feeding aggregations within coastal meadows in early summer in Lake Clark National Park and Preserve, Alaska, USA, are one such example. These indices reflect the target population (brown bears residing within the park) and temporary immigrants (i.e., bears drawn from outside the park boundary). To properly account for the effects of temporary immigration, we integrated the index data with abundance data collected via park-wide distance sampling surveys, the latter of which properly addressed the detection process. By assuming that the distance data provide inference on abundance and the index counts represent some combination of abundance and temporary immigration processes, we were able to decompose the relative contribution of each to overall trend. We estimated that the density of brown bears within our study area was 38–54 adults/1,000 km<sup>2</sup> during 2003–2019 and that abundance increased at a rate of approximately 1.4%/year. The contribution of temporary immigrants to overall trend in the index was low, so we created 3 hypothetical scenarios to more fully demonstrate how the integrated approach could be useful in situations where the composite trend in meadow counts may obscure trends in abundance (e.g., opposing trends in abundance and temporary immigration). Our work represents a conceptual advance supporting the integration of legacy index data with more rigorous data streams and is broadly applicable in cases where trends in index values may represent a mixture of population processes.

Minimal responses of water quality and stream biota to partial retrofit stormwater management in a suburban neighborhood. PLoS ONE 9: e85011 \| Abstract \| Download \| Publisher Website	January 2014	Decentralized stormwater management approaches (e.g., biofiltration swales, pervious pavement, green roofs, rain gardens) that capture and detain, infiltrate, and filter runoff are now more commonly used throughout catchments to minimize the impacts of stormwater runoff from impervious surfaces on aquatic ecosystems. However, there is little research on the effectiveness of retrofit, parcel-scale stormwater management for improving downstream ecosystem health. A reverse auction was used to encourage homeowners to mitigate stormwater on their property within the suburban, 1.8 km2 Shepherd Creek catchment in Cincinnati, Ohio (USA). In 2007–2008, 165 rain barrels and 81 rain gardens were installed on 30% of the properties in four experimental (treatment) subcatchments, and two additional subcatchments were maintained as controls. At the base of the subcatchments, we sampled monthly baseflow water quality, and seasonal (5x/year) physical habitat, macroinvertebrate and periphyton assemblages in the streams for the three years before and after treatment implementation. There were very few significant differences in water quality and biotic variables from rain garden and rain barrel installations. Observed responses show trends (p < 0.10) toward increased iron, conductivity, filamentous algae, and macroinvertebrate diversity in control sites, with a corresponding lack of change (or decrease) in experimental sites, indicating a significant treatment effect. We attributed the minimal shifts in stream water quality and biota to the relatively small reductions in stormflow volume associated with the treatment. Improvement in overall stream health is unlikely without treatment of all major impervious surfaces (including roads, apartment buildings, and parking lots), stream bank and riparian improvements, and mitigation of septic tanks and other water quality stressors. Despite the challenges of catchment-scale restoration, additional research is needed to determine the extent of management necessary to improve the health of stream ecosystems.

Building green infrastructure via citizen participation: a six-year study in the Shepherd Creek (Ohio). Environmental Practice 14:57-67. \| Abstract \| Publisher Website	March 2012	Green infrastructure at the parcel scale provides critical ecosystem goods and services when these services (such as flood mitigation) must be provided locally. Here we report on an approach that encourages suburban landowners to mitigate impervious surfaces on their properties through a voluntary auction mechanism. We used an economic incentive to place rain gardens and rain barrels onto parcels in a 1.8-km2 watershed near Cincinnati, Ohio. A comprehensive hydrologic, water-quality, and ecological monitoring campaign documented environmental conditions before and after treatment. In 2007 and 2008, we engaged private landowners through a reverse auction to encourage placement of one rain garden and up to four rain barrels on their property. The program led to the installation of 83 rain gardens and 176 rain barrels onto more than 20% of the properties, and preliminary analyses indicate that the overall discharge regime was altered by the treatments. The length of the study (six years) may have precluded observation of treatment effects on water quality and aquatic biological communities, as we would expect these conditions to respond more slowly to management changes. These distributed storm-water installations contributed to ecosystem services such as flood protection, water supply, and water infiltration; provided benefits to the local residents; and reduced the need for larger, expensive, centralized retrofits (such as deep tunnel storage).

Methods in Ecology & Evolution. https://doi.org/10.1111/2041-210X.14102. \| Abstract	April 2023	Surveillance programs are essential for detecting emerging pathogens and often rely on molecular methods to make inference about the presence of a target disease agent. However, molecular methods rarely detect target DNA perfectly. For example, molecular pathogen detection methods can result in misclassification (i.e., false positives and false negatives) or partial detection errors (i.e., detections with ‘ambiguous’, ‘uncertain’, or ‘equivocal’ results). Typically, these partial observations are either discarded or censored from the data; this, however, disregards information that may be exploited to make inference to the true state. Here, we develop a Bayesian hierarchal framework that accommodates false negative, false positive, and uncertain detections to improve inference to the occupancy of a pathogen. We apply our modeling framework to a case study of the fungal pathogen <i>Pseudogymnoascus destructans</i> (Pd) identified in Texas bats at the invasion front of white-nose syndrome. To improve future surveillance programs, we provide guidance on sample sizes required to be 95% certain a target organism is absent from a site. We found that the presence of uncertain detections increased the variability of resulting posterior probability distributions of pathogen occurrence, and estimates of required sample size were very sensitive to prior information about occupancy and prevalence. In the Pd case study, we found that the posterior probability of occupancy was very low in 2018, but approached 1 in 2020, reflecting increasing prior probabilities of occupancy and prevalence elicited from a manager.Our modeling framework provides the user a posterior probability distribution of pathogen occurrence, which allows for subjective interpretation by the decision-maker. To help readers apply and use the methods we developed, we also provide an interactive RShiny app that generates target species occupancy estimation and sample size estimates to make these methods more accessible to the scientific community. This modeling framework and sample size guide will be useful to improving inferences from molecular surveillance data about emerging pathogens, non-native invasive species, and endangered species where misclassifications and ambiguous detections are known to occur.

The recent invasion of a highly pathogenic chytrid fungus, <i>Batrachochytrium salamandrivorans</i> (<i>Bsal</i>), across Europe has led to salamander mass mortality. To date, it remains unclear whether <i>Bsal</i> will cause salamander mass mortalities in North America. Here, we tested the <i>Bsal</i> susceptibility of eight wild-caught salamander species (<i>Plethodon cinereus</i>, <i>P. glutinosus</i>, <i>P. montanus</i>, <i>P. cylindraceus</i>, <i>Desmognathus fuscus</i>, <i>D. wrighti, Eurycea wilderae</i>, and <i>Notophthalmus viridescens</i>) by inoculating individuals sequentially with a low (10,000 zoospores) and high (500,000 zoospores) <i>Bsal</i> dose<i>.</i> Overall, we found rapid and complete mortality of <i>N. viridescens</i> accompanied with high-<i>Bsal</i> infections (> 200,000 <i>Bsal</i> zoospores) and severe <i>Bsal</i> lesions distributed across the body and deep within the skin. In contrast, we found low mortality of plethodontid salamanders, where only 5 of 60 (8%) <i>Bsal</i>-exposed individuals died over the course of the experiment. In general, plethodontid salamanders experienced moderate <i>Bsal</i> infections (~ 4000 <i>Bsal</i> zoospores) with small numbers of <i>Bsal</i>-type lesions limited to the head and lateral body. Following the first <i>Bsal</i> inoculation, we found that <i>Bd</i> co-infections negatively affected <i>Bsal</i> infections, suggesting cross reactivity of the immune system or competitive exclusion, but this pattern did not persist following the second inoculation. We also found that <i>Bsal</i> infection intensity decreased over time following the second higher <i>Bsal</i> inoculation, suggesting evidence of immune priming. Throughout the experiment, all species and treatments experienced stable or increasing body condition over time. Lastly, ancestral state reconstruction of <i>Bsal</i> susceptibility indicated that although the most recent common ancestor (MRCA) of the family Plethodontidae is resistant to <i>Bsal</i>, the MRCA of the genus <i>Plethodon</i> is tolerant of <i>Bsal</i>. This highlights the variation in <i>Bsal</i>-infection outcomes across Plethodontidae. Collectively, our results suggest that Plethodontidae salamanders differ in their <i>Bsal</i> susceptibility, with some species less impacted than others, which will likely have consequences for their conservation and management.

Ecology 102: e03315. \| Abstract \| Download \| Publisher Website	March 2021	First-order dynamic occupancy models (FODOMs) are a class of state-space model in which the true state (occurrence) is observed imperfectly. An important assumption of FODOMs is that site dynamics only depend on the current state and that variations in dynamic processes are adequately captured with covariates or random effects. However, it is often difficult to understand and/or measure the covariates that generate ecological data, which are typically spatiotemporally correlated. Consequently, the non-independent error structure of correlated data causes underestimation of parameter uncertainty and poor ecological inference. Here, we extend the FODOM framework with a second-order Markov process to accommodate site memory when covariates are not available. Our modeling framework can be used to make reliable inference about site occupancy, colonization, extinction, turnover, and detection probabilities. We present a series of simulations to illustrate the data requirements and model performance. We then applied our modeling framework to 13 yr of data from an amphibian community in southern Arizona, USA. In this analysis, we found residual temporal autocorrelation of population processes for most species, even after accounting for long-term drought dynamics. Our approach represents a valuable advance in obtaining inference on population dynamics, especially as they relate to metapopulations.

Most applications of single-scale occupancy models do not differentiate between availability and detectability, even though species availability is rarely equal to one. Species availability can be estimated using multi-scale occupancy models, and the availability process includes elements of species movement, behavior, and phenology. However, for the practical application of multi-scale occupancy models, it can be unclear what a robust sampling design looks like and what the statistical properties of the multi-scale and single-scale occupancy models are when availability is less than one.<br><br>2. Using simulations, we explore the following common questions asked by ecologists during the design phase of a field study: (Q1) what is a robust sampling design for the multi-scale occupancy model when there are <i>a priori</i> expectations of parameter estimates?, (Q2) what is a robust sampling design when we have no expectations of parameter estimates?, and (Q3) can a single-scale occupancy model with a random effects term adequately absorb the extra heterogeneity produced when availability is less than one and provide reliable estimates of occupancy probability?.<br><br>3. Our results show that there is a tradeoff between the number of sites and surveys needed to achieve a specified level of acceptable error for occupancy estimates using the multi-scale occupancy model. We also document that when species availability is low (< 0.40 on the probability scale), then single-scale occupancy models underestimate occupancy by as much as 0.40 on the probability scale, produce overly precise estimates, and provide poor parameter coverage. This pattern was observed when a random effects term was and was not included in the single-scale occupancy model, suggesting that adding a random-effects term does not adequately absorb the extra heterogeneity produced by the availability process. In contrast, when species availability was high (> 0.60), single-scale occupancy models performed similarly to the multi-scale occupancy model.<br><br>4. As a companion, we provide an RShiny app that allows users to further explore our results and sampling designs across a number of different scenarios https://gdirenzo.shinyapps.io/multi-scale-occ/. Our results suggest that unaccounted for availability can lead to underestimating species distributions when using single-scale occupancy models, which can have large implications on ecological inference and predictions for practitioners, such as those working at the front lines of invasion ecology, disease emergence, and species conservation.

Greater Roadrunners (Geococcyx californianus) are widespread throughout arid regions of the southwestern United States. As a large predatory bird, roadrunners require large home ranges and their relatively low densities and secretive nature make surveys and observations a challenge. However, roadrunners are among the most well-known and charismatic avian species in the Southwest and draw much attention from residents and visitors. Distribution of roadrunners and habitat features of importance to roadrunners in urban and suburban environments have not been described, and it is not known how development may affect roadrunner populations. Although roadrunners are occasionally seen in southwestern cities, urbanization may eliminate local populations. We used public sighting information to document roadrunner locations in metropolitan Tucson, Arizona. We explored and, when possible, evaluated the types of biases (e.g., species misidentification, erroneous information, non-response and self-selection biases) inherent in public information surveys. We also employed researcher-based, randomly distributed surveys to examine roadrunner distribution and habitat use, to estimate the amount of survey effort required to detect a low-density elusive species like roadrunners, and to establish a sample of sightings based on random sampling. We received 1,449 reports of roadrunner sightings from the public and saw 52 roadrunners on 281 researcher-based surveys. The general pattern of distribution of roadrunner sightings in Tucson was similar from both public and researcher surveys, forming a broad band around the edge of Tucson with few or no sightings in the city center. Tucson residents reported seeing roadrunners most often in areas with housing densities of 2.5-7.5 residences per ha (RHA) and non-native vegetation, and less often than expected in areas with washes, natural open space, native vegetation, graded vacant land, and housing densities of 7.5-15 RHA. In contrast, during our random surveys we found roadrunners closer to washes and areas with housing densities of 7.5¬¬-15 RHA, indicating that roadrunners used these land cover-types more frequently than was reported from the public. In general, however, roadrunners used a variety of urban and suburban environments and could be seen almost anywhere in the city except for areas with the highest housing densities (>15 RHA). Public survey information provided a great deal of usable data quickly and inexpensively but reflected where people saw and reported roadrunners. Interpretations of relative abundance or habitat preference need to be made cautiously.

Springer Book Publishers, New York, NY. \| Abstract \| Publisher Website	March 2009	Abstract: An obvious consequence of exurban land development is fragmentation of natural areas. Fragmentation leaves patches of habitat of various sizes, which can become increasingly isolated as development continues. A compelling approach to mitigation is the creation of corridors. Corridors in their simplest form are strips of habitat that connect patches and allow for wildlife movements. Intuitively, corridors make sense and land planners and managers often find them useful in land conservation. However, do wildlife corridors perform as expected? Do they work for all species? And how should they be configured (e.g., width, length, placement)? This chapter addresses these and other questions related to wildlife corridors and exurban land development.

DOI: 10.3390/life11121288 \| Abstract \| Publisher Website	November 2021	With rapidly changing marine ecosystems, shifts in abundance and distribution are being documented for a variety of intertidal species. We examined two adjacent populations of Pacific razor clams (Siliqua patula) in lower Cook Inlet, Alaska. One population (east) supported a sport and personal use fishery, but this has been closed since 2015 due to declines in abundance, and the second population (west) continues to support commercial and sport fisheries. We used gene expression to investigate potential causes of the east side decline, comparing razor clam physiological responses between east and west Cook Inlet. The target gene profile used was developed for razor clam populations in Alaska based on physiological responses to environmental stressors. In this study, we identified no differences of gene expression between east and west populations, leading to two potential conclusions: (1) differences in factors capable of influencing physiology exist between the east and west and are sufficient to influence razor clam populations but are not detected by the genes in our panel, or (2) physiological processes do not account for the differences in abundance, and other factors such as predation or changes in habitat may be impacting the east Cook Inlet population

Evaluating a tandem human-machine approach to labelling of wildlife in remote camera monitoring. Ecological Informatics 77:e102257 https://doi.org/10.1016/j.ecoinf.2023.102257. \| Abstract \| Download \| Publisher Website	August 2023	Remote cameras (“trail cameras”) are a popular tool for non-invasive, continuous wildlife monitoring, and as they become more prevalent in wildlife research, machine learning (ML) is increasingly used to automate or accelerate the labor-intensive process of labelling (i.e., tagging) photos. Human-machine hybrid tagging approaches have been shown to greatly increase tagging efficiency (i.e., time to tag a single image). However, those potential increases hinge on the extent to which an ML model makes correct vs. incorrect predictions. We performed an experiment using a ML model that produces bounding boxes around animals, people, and vehicles in remote camera imagery (MegaDetector) to consider the impact of a ML model's performance on its ability to accelerate human labeling. Six participants tagged trail camera images collected from 12 sites in Vermont and Maine, USA (January–September 2022) using three tagging methods (one with ML bounding box assistance and two without assistance). We used a generalized linear mixed model to examine the influence of ML model performance and tagging method on tagging efficiency. We found that ML bounding boxes offer significant improvement in tagging efficiency when labelling data compared to unassisted tagging. Additionally, the time taken to label with bounding boxes was not statistically different from an unassisted tagging approach. However, we found that gains in efficiency are contingent on the ML algorithm's performance and that incorrect ML predictions, particularly the 4.2% false positive and 3.6% false negative predictions, can slow the tagging process compared to a non-hybrid approach. These findings indicate that although practitioners usually forgo the production of bounding boxes when selecting a data labelling process due to the increased effort, ML bounding box-assisted tagging can offer an efficient method for labeling. More broadly, ML-assisted data labelling offers an opportunity to accelerate the analysis of trail camera imagery, but an assessment of the ML model's performance can illuminate whether the hybrid-tagging approach is ultimately a help or hinderance.

Auk 126:187-197. \| Abstract	January 2009	Abstract.—Most scrub–shrub bird species are declining in the northeastern United States, and these declines are largely attributed to regional declines in habitat availability. American Beaver (Castor canadensis; hereafter “beaver”) populations have been increasing in the Northeast in recent decades, and beavers create scrub–shrub habitat through their dam-building and foraging activities. Few systematic studies have been conducted on the value of beaver-modified habitats for scrub–shrub birds, and these data are important for understanding habitat selection of scrub–shrub birds as well as for assessing regional habitat availability for these species. We conducted surveys in 37 beaver meadows in a 2,800-km2 study area in western Massachusetts during 2005 and 2006 to determine the extent to which these beaver-modified habitats are used by scrub–shrub birds, as well as the characteristics of beaver meadows most closely related to bird use. We modeled bird abundance in relation to microhabitat-, patch-, and landscape-context variables while adjusting for survey-specific covariates affecting detectability using N-mixture models. We found that scrub–shrub birds of regional conservation concern occupied these sites and that birds responded differently to microhabitat, patch, and landscape characteristics of beaver meadows. Generally, scrub–shrub birds increased in abundance along a gradient of increasing vegetation complexity, and three species were positively related to patch size. We conclude that these habitats can potentially play an important role in regional conservation of scrub–shrub birds and recommend that conservation priority be given to larger beaver meadows with diverse vegetation structure and composition.

DOI: 10.1002/jwmg.22630. \| Abstract \| Publisher Website	July 2024	An important symbolic and subsistence animal for many Native American Tribes, the moose (<i>Alces alces</i>; mos in Algonquin, Penobscot language) has been under consistent threat in the northeastern United States because of winter tick (<i>Dermacentor albipictus</i>) parasitism over the past several decades, causing declines in moose populations throughout the region. This decline has raised concern for Tribes and agencies that are invested in moose. Given this concern, it is increasingly important to effectively monitor and develop strategies to manage winter ticks to address consistent population declines of moose due to winter ticks. The Penobscot Nation developed a novel strategy to sample questing winter ticks (i.e., ticks that are actively seeking hosts) using a plot-based sampling protocol that may be suitable for heterogeneous habitats. We deployed this protocol in the northeastern United States in 2022 during the tick questing period (Sep–Dec) on Penobscot Nation sovereign trust lands, the White Mountain National Forest and Umbagog National Wildlife Refuge, and western-central Massachusetts, USA. We analyzed the data using occupancy and N-mixture models. Detection probability peaked during mid-October and tick occupancy and abundance were greatest at sites with intermediate understory vegetation height. The sampling protocol was successful at sampling ticks in Massachusetts, where abundances were expected to be low, indicating that it may be useful for studies planning to monitor winter tick distribution and abundance in areas with sub-optimal moose habitat and where winter tick abundance is expected to be low. This approach may also benefit managers or researchers intending to monitor many species of hard ticks, and where imperfect detection is expected.

Environmental Pollution 330: 121678. https://doi.org/10.1016/j.envpol.2023.121678 \| Abstract	May 2023	Mercury (Hg) is a widespread element and persistent pollutant, harmful to fish, wildlife, and humans in its organic, methylated form. The risk of Hg contamination is driven by factors that regulate Hg loading, methylation, bioaccumulation, and biomagnification. In remote locations, with infrequent access and limited data, understanding the relative importance of these factors can pose a challenge. Here, we assessed Hg concentrations in an apex predator fish species, lake trout (<i>Salvelinus namaycush</i>), collected from 14 lakes spanning two National Parks in southwest Alaska, U.S.A. We then examined factors associated with the variation in fish Hg concentrations using a Bayesian hierarchical model. We found that Hg concentrations in lake water were uniform and very low. Conversely, Hg concentrations in lake trout were variable and, in some lakes, very high, exceeding Alaska’s human consumption threshold at half of our study sites. Additionally, model results indicated that fish age and, to a lesser extent, body condition best explained variation in Hg concentration among fish within a lake, with Hg elevated in older, thinner lake trout. Other factors, including plankton methyl Hg content, fish species richness, volcano proximity, and glacier loss, best explained variation in lake trout Hg concentration among lakes. Collectively, these results provide evidence that multiple, hierarchically nested factors control fish Hg levels in these lakes.
