Project	Completion Date
American eel age and growth assessment in the Roanoke River, North Carolina.	June 2018	We will systematically sample American eels from the Roanoke River in North Carolina. Eels will be sampled near the river mouth, upstream above and below high dams to specifically characterize the American eel population within the Roanoke River mainstem. Additionally, the age, sex, and presence of a parasite in swimbladders of individual fish will be determined from sampled eels. Finally, age, growth, and mortality of American eels will be modeled in relation to location sampled, sex, and the presence of parasites as data allow. Information from these objectives will be synthesized to provide a better understanding of American eel ecology and management.

Environmental Determinants of Sex in Fishes: Endocrine Disruptors and Water Temperature	September 2016	The mechanisms of phenotypic sex determination in fishes are well understood but the process can be easily altered by the fish’s environment. Because fish are in intimate contact with the water, compounds within the water, or the quality of the water itself, can directly influence fish physiology and disrupt or alter the normal hormonal cascade that leads to their phenotypic sex. The objectives of this proposal are to: 1. conduct a survey for the presence of EDCs and intersex in common fish at sites along a flowing water system influenced by PCB contamination and municipal wastewater effluent, and 2. determine whether southern flounder in two brackishwater nursery areas have skewed sex-ratios based on temperature using molecular biomarkers and physiological indicators (Na/K ATPase). This work will provide critical insight into the role of anthropogenic chemicals (EDCs) and natural temperature variations on important aquatic species.	None
Robust Redhorse Recovery and Habitat Restoration: Assessing Water Quality Stressors and Food Web Contaminant Dynamics	December 2017	The robust redhorse (Moxostoma robustum) is a rare and imperiled, large catostomid fish found in only three regulated river drainages in the southeastern U.S. It has large pharyngeal teeth for crushing mollusks and other invertebrates known to sequester anthropogenic contaminants. The robust redhorse has been negatively affected by habitat modification and fragmentation from hydroelectric dams, introduced species, sedimentation, and water pollution and is protected by state endangered status in Georgia and North Carolina. Previous research by the authors and their students on physical instream habitat suitability has shown that habitat suitability will be enhanced by prescribed flow augmentations from hydroelectric dam releases; however, the impacts of water quality and contaminant loads remain unknown. In addition to the unknown effects of traditional organic and inorganic contaminants, recent research suggests that the impact of emerging contaminants, such as endocrine disrupting compounds, may be of significant detriment to fishes in the Pee Dee River. To further elucidate the impact and potential threat of water quality and contaminant dynamics on the robust redhorse, we proposed six research objectives to pursue in the Pee Dee River of North Carolina and South Carolina. We will (1) conduct systematic field sampling of habitat and food web components, (2) conduct experimental field bioassay exposures with captively-propagated fish, (3) perform laboratory analyses of traditional and emerging contaminants (4) determine aquatic food web structure, (5) develop population and food web models to describe effects of habitat and water quality modifications, and (6) synthesize results for robust redhorse recovery from population and ecosystem perspectives. This research is unique in that it will yield results and inference that are descriptive (systematic sampling), explanatory (experimental bioassays, food web analyses), and predictive (population and food web modeling) at multiple scales and across disciplines to inform decision making and management. If the proposed research is funded and conducted, it will guide management objectives and goals for species recovery and habitat restoration.

Assessing the effects of the National Park Service predator and vehicle management practices on nesting shorebirds at Cape Hatteras National Seashore	November 2017	The study will be comprised of two components. 1) An examination of historic predator and vehicle management practices and American Oystercatcher distribution, abundance, and productivity data to assess whether these practices are meeting the National Seashores short and long-term management objectives. This work will model spatial and temporal patterns of American Oystercatcher abundance and productivity from 1998 to the present in relation to relevant covariates including: the proximity and intensity of predator management, vehicle and pedestrian closure type, vehicle and pedestrian intensity, and causes of nest failure. Response variables will include the number of nesting pairs, hatching success, and fledging success. 2) An experimental evaluation of current vehicle and pedestrian closures for breeding American Oystercatchers to determine the relationship between closure type, size, and duration and oystercatcher behavior, physiology, and nesting success. Methods developed for American Oystercatchers at Cape Look National Seashore from 2010 – 2012 will be used to quantify the sensitivity of nesting birds to vehicles and pedestrians. Digital video and heart rate monitors embedded in artificial eggs will record changes in bird behavior and physiology in relation to the proximity of vehicles and pedestrians. Studies of the movement, activity patterns, and habitat use of radio-tagged birds will quantify the habitat requirements and behavioral responses of adults and pre-fledging chicks to various types of anthropogenic disturbance.

Responses of Targeted Herpetological Communities to Fire Management Practices in Pine-Oak Forests of the Great Smoky Mountains National Park	July 2014	Forest managers at the Great Smoky Mountains National Park are working to reintroduce a fire regime that once characterized the southwest portion of the park. However, managers are uncertain about the effects of fire - especially detrimental effects - on populations of amphibians and reptiles. This project will investigate relationships between prescribed fire management and herptile community response in this area of the park. The investigation will rely on field sampling and predictive modeling approaches. The outcome of this study, along with a companion project on bird community associations with fire management, will help inform park managers about responses by forest fauna to the reintroduction of fire.

Modeling suitable habitat for the robust redhorse in the Pee Dee River.	May 2012	The robust redhorse, Moxostoma robustum, was rediscovered in 1980, 110 years after its description. This fish was first discovered by Edward Cope in the Yadkin/PeeDee River of North Carolina in 1869. However, this largest of the redhorse species was lost to science until it was recently rediscovered in Georgia. Historically, the fish was found in large Atlantic slope rivers from the Altamaha River in Georgia to the Pee Dee River in North and South Carolina. Habitat loss and spawning disruption by dams were identified by the Robust Redhorse Conservation Committee as a one of several threats to the robust redhorse. Robust redhorse historically occurred in the Pee Dee River between Tillery Dam and Blewett Falls Lake, but are presumed to be extirpated from that reach. Habitat analyses in the lotic reach upstream of Blewett Falls Lake, based on the newly developed habitat suitability criteria for the robust redhorse, would inform river managers on the feasibility of potential reintroduction of the species into that reach. Cooperative research is underway to accomplish the following objectives with the ultimate goal to improve our understanding of robust redhorse reproductive and habitat ecology and guide management to ensure the long-term survival and population enhancement of this imperiled species. 1. Quantitatively describe instream habitat availability under varying flow volumes in the unimpounded, lotic reach of the Pee Dee River upstream of Blewett Falls Lake. 2. Model the quantity of suitable robust redhorse habitat in that reach under varying flows, based on habitat suitability criteria for the species (spawning and non-spawning). This research will improve our understanding of a little-known and rare imperiled fish, that may require specific management activities, such as population reintroduction or augmentation in this and other regulated river systems.

Sicklefin Redhorse Ontogeny, Recruitment, and Priority Habitats in Regulated Rivers.	June 2017	The sicklefin redhorse Moxostoma sp. (Catostomidae) is a potamodromous, undescribed and imperiled fish in the southern Appalachian Mountains. It is a candidate for protection under the Endangered Species Act, but little is known of its biology and ecology. Previous research by Kwak and others increased the knowledge of sicklefin redhorse reproductive ecology and behavior, based on adult fish. This research will examine the early life history and ecology of the sicklefin redhorse and its congeners, especially as related to habitat suitability, dams, and invasive predators. Our primary objectives include (1) estimate the reproductive success of the sicklefin redhorse at early life stages in terms of abundance and growth, relative to sympatric congeneric species; (2) describe ontogenetic shifts in sicklefin redhorse habitat use and suitability during early life stages and relative to that of adult fish; (3) determine the effects of introduced fishes on sicklefin redhorse recruitment; and (4) add to the spatial database on important sicklefin redhorse spawning areas. Genetic techniques will be applied to identify larval and juvenile fish. Improved knowledge, particularly of the early life history of the species, will inform and guide critical future decisions in river management and dam relicensing that directly affect the survival of this imperiled fish.

Characterizing habitat suitability for American Shad in the Yadkin-Pee Dee River	December 2013	In the Yadkin – Pee Dee River Basin in South Carolina and North Carolina, the extent of fish migrations has been greatly reduced by the presence of dams. Habitat loss due to dam construction is one of the factors contributing to declines of anadromous fish species along the Atlantic Coast. At present, there are no facilities for fish passage at Yadkin-Pee Dee dams, but options are being explored. The primary objective of this study is to characterize and evaluate the suitability of fish habitat upstream of dams on the Yadkin - Pee Dee River. Our focal species will be anadromous American shad Alosa sapidissima, with potential generalization to other species. Characterizing the suitability of habitat above the Yadkin – Pee Dee Hydroelectric Project dams is an important step in guiding diadromous fish passage and restoration efforts.	None

Factors influencing native aquatic plant revegetation success for enhanced sport fish habitat in North Carolina Piedmont reservoirs	June 2016	We propose a systematic and quantitative controlled-experience field experiment to assess the relative habitat use of native and invasive plants for sport fish support functions at multiple spatial scales. Our goal is to understand factors contributing to aquatic vegetation establishment, costs of vegetation establishment, and sport fish habit value on both a micro- and macro-habitat scale. Research Objectives: Objective 1. Compile an extensive literature review and develop a complete reference guide on vegetation native to North Carolina and revegetation techniques with an emphasis on sport fish habitat in Piedmont reservoirs. Objective 2. Evaluate the cost per unit established of selected native aquatic plants identified in Objective 1 for their sport fish habitat value. In addition, this objective will determine native plant establishment success in the presence or absence of hydrilla and the benefit of herbivore exclosures on native plant establishment and spread. Objective 3: Assess the relative habitat use of native and invasive aquatic plants for sport fish support functions at multiple spatial scales. Objective 4: Disseminate project results to resource managers and stakeholders.	None
Stocked trout survival, behavior, and ecology in North Carolina streams	December 2015	The goal of this research is to define the extent and causes of stocked trout migration and mortality among species and to elucidate the mechanisms responsible. We will combine intensive and extensive studies to determine the persistence of stocked trout in designated reaches and streams, and then the associated processes and mechanisms will be sought in a subset of stream reaches. Fish behavior and ecology will be examined to gain an understanding of the factors that may affect stocked fish growth, condition, and survival. Results may be used to inform and guide management actions to improve resource management strategies and to educate fishery constituents and the public.	None
A comprehensive examination of endocrine disrupting compounds and intersex fish in North Carolina water bodies.

Laboratory assessment of endocrine disruption and intersex in Pee Dee River water mixtures.	None
Assessing endangered marsh rabbit and woodrat habitat use and feral cat population dynamics using photographic, video, and RFID capture-recapture data	July 2016	The lower keys marsh rabbit (Sylvilagus palustris hefneri) and the Key Largo woodrat (Neotoma floridana smalli) are endangered species endemic to the Florida Keys. Their survival is threatened by a variety of factors including habitat change, sea level rise, and introduced predators like feral cats that thrive in human-dominated landscapes. Research has suggested that management actions focusing on the interactions among these factors are needed. Current management objectives include assessing the co-occurrence of marsh rabbits and cats, estimating the distribution and abundance of feral cat populations, and evaluating the efficacy of artificial structures and other restoration efforts for woodrats. We propose to use photographic, video, and RFID capture-recapture methodologies to inform the management of these two endangered species. Our primary objectives are to: (1) use camera trapping methods to validate marsh rabbit pellet count occupancy estimates and to estimate population size and movement of feral cats, and (2) use camera traps, video, and RFID tag monitoring to assess use of artificial structures by woodrats and to estimate the population size and movement of feral cats in woodrat habitat.

Assessing the effects of the National Park Service prescribed fire program on the breeding bird community in Great Smoky Mountains National Park	November 2014	The southwestern corner of Great Smoky Mountains National Park (GRSM), with its dry pine and oak-hickory forests, steep slopes drained by small tumbling creeks, scattered old home sites, wetlands, and extensive fire history, provides diverse habitat for a variety of birds. Many of these species are restricted to habitats declining elsewhere and limited in the park by past fire management practices. Prescribed fire has been introduced in the past 20 years, as well as a policy allowing naturally caused fires to burn. The resulting mosaic of mature trees, dense regeneration and open savannah-like forest has changed the landscape significantly. This area was the last known habitat for the endangered red-cockaded woodpecker; several other bird species whose habitat is improved by fire are likely to be present. Characterizing the habitat and identifying breeding birds will guide the park in fire management decisions and help improve habitat. This project will provide fundamental information to evaluate possible reintroduction of red-cockaded woodpeckers and target habitat management for other bird species of concern.	None
Estimation of United States Atlantic Red Snapper Abundance (phase II)	August 2025	Previously collected trap and video data, along with ROV survey data, will be used to estimate red snapper abundance within an integrated population modeling framework. Population models require spatial replication over the study area of interest and temporal replicates that are independent but close enough in time to ensure population closure. The proposed study would use trap and video count data to estimate detection probability and abundance of red snapper with an integrated populaiton model fitted in a Bayesian framework. Covariates that influence red snapper detection probability and abundance will be used to predict abundance (with associated uncertainty) at habitats that are similar to SEFIS sampling sites but not sampled. We will conduct workshops with reef fishery stakeholders to assist with identification of non-sampled hard bottom habitats. Based on past work, covariates important to red snapper abundance are likely to include bottom temperature, depth, latitude, and substrate type. A key question with this work is the spatial area that an individual SEFIS trap and video station effectively samples. Recently, project collaborators measured the response of red snapper around baited traps using fine spatial scale telemetry data, and response distance information will be used to estimate the sampled area at trap stations. Red snapper densities derived from ROV surveys will also be estimated at habitat types generally not sampled by SEFIS. Spatial maps of important covariates and habitat type will be used to generate abundance by area across the study region. These individual abundance values would be summed to estimate abundance of red snapper (with associated uncertainty) in the US Atlantic.	None
Aquatic species distribution modeling to inform recovery and conservation	September 2028	The southeastern United States is home to almost 40% of the world’s freshwater mussel species and 91% of US mussel species, 79% of the freshwater fishes in the U.S. and Canada and approximately 33% of the world’s crayfish species. This incredible biodiversity presents unique challenges because of the increasing threats (e.g., land conversion, habitat loss, changes in flow, increased sedimentation) and predicted urban growth facing the southeastern U.S. Given these challenges within the southeastern U.S. for aquatic species we propose the following work to aid in this process: 1) develop iSDMs for a suite of priority species using all available data, 2) estimate drivers of the distribution of priority species at multiple scales, and 3) develop a Decision Support Tool to provide a transparent, rigorous, and reproducible foundation for evaluating a suite of conservation actions. This project will support management of imperiled species multiple ways. 1), the project will integrate disparate data types to uncover drivers of species trends and distributions; 2), the project will provide high-resolution predicted distributional data to inform consultation decisions for stakeholders within these species’ ranges; 3), integrated species distribution models can be used to link management actions to expected species distributions, thereby informing decision-making. This project is a collaboration among the NC Unit, NC State University, and U.S. Fish and Wildlife Service.	None
Integrating Research and Monitoring Programs to Quantify Abundance, Occupancy, and Persistence Probability: Canada Lynx at the Edge of their Southern Range	December 2025	This study aims to develop and apply methods that combine less expensive survey methods (e.g., detection/non-detection data) with targeted research studies (e.g., capture-recapture) to estimate lynx abundance, quantify lynx population growth and distribution, and identify landscape variables that influence lynx persistence.

Assessing the responses of breeding shorebirds to military jet overflights of the Core MOA at Cape Lookout National Seashore	July 2012	The U.S. Marine Corps and the National Park Service (NPS) have recently agreed to lower the altitude for tactical speed operations (>250 kts) in the Core Military Operations Area (Core MOA, Figure 1) over Cape Lookout National Seashore (CALO). The Core MOA allows high speed (> 250 knots) ingress/egress over a portion of CALO. Previously, the tactical speed ceiling through this Core MOA was set at 10,000 ft; the new ceiling is set at 3,000 ft. A conservation question emanating from this change is whether the change could increase the disturbance of nesting shorebirds. In a letter dated 17 September 2008 from the NPS (David Vela, SE Regional Director) to the U.S. Marines (Colonel Ruvalcaba, FAA SE Region), the NPS expressed interest in a 3-yr research study to “study the noise effects of the MOA on nesting shorebirds,” with unresolved issues including “1) Does noise from low flying aircraft disrupt adults from incubating nests?, 2) How long does it take for the adult to return to the nest?, 3) If adults are disturbed during incubation on several occasions, will they eventually abandon the nest?, 4) Does the noise from low flying aircraft cause adults to leave the area while ‘guarding’ flightless chicks?, 5) What will be the level of disturbance based on the altitude of the aircraft?” In this letter, the NPS summarizes that it does not object to implementing the MOA during the months of May-July on “an interim basis of 3 years during the nesting season for study purposes,” to “gather information on the effects that the MOA would generate on protected species.” In particular, the NPS is interested in understanding the effects on state- and local-listed nesting shorebirds, including the American Oystercatcher (Haematopus palliatus), Least Tern (Sternula antillarum), Common Tern (Sterna hirundo), Black Skimmer (Rynchops niger), and Wilson’s Plover (Charadrius wilsonia) which are all listed as Species of Special Concern in North Carolina, and the Gull-Billed Tern (Gelochelidon nilotica) which is listed as threatened in North Carolina and is a species of low population size and conservation concern according to the National Audubon Society Watchlist (NCWRC 2008, NAS 2009). This interest in studying the potential effects of aircraft overflights on these nesting shorebird species arises from NPS Management Policy 4.4.2.3., which states that “The National Park Service will inventory, monitor, and manage state and locally listed species in a manner similar to its treatment of federally listed species to the greatest extent possible. In addition, the Service will inventory other native species that are of special management concern to parks (such as rare, declining, sensitive, or unique species and their habitats) and will manage them to maintain their natural distribution and abundance.” Additionally, the NPS is mandated to protect wildlife (Migratory Bird Treaty Act), ensure wilderness values, comply with NEPA, and comply with Public Law 100-91 “National Parks Overflights Act.” To address these statutory responsibilities related to the Core MOA, the NPS proposes the need to study the effects of reducing the overflight ceiling from 10,000 to 3,000 ft on nesting shorebirds at Cape Lookout National Seashore.

Designing sustainable landscapes for bird populations in the eastern United States.	June 2011	The overall objective of this proposal is to develop a consistent methodology and to enhance the capacity of states, joint ventures and other partners to assess and design sustainable landscapes for birds and other wildlife in the eastern United States. Specifically, this project would develop and implement a framework and tools to 1) assess the current capability of habitats in ecoregions in the eastern United States to support sustainable bird populations; 2) predict the impacts of landscape-level changes (e.g., from urban growth, conservation programs, climate change) on the future capability of these habitats to support bird populations; 3) target conservation programs to effectively and efficiently achieve objectives in State Wildlife Action Plans and bird conservation plans and evaluate progress under these plans; and 4) enhance coordination among partners during the planning, implementation and evaluation of habitat conservation through conservation design.

Expanding the range and scope of the Designing Sustainable Landscapes to the entire South Atlantic Landscape Conservation Cooperative area.	March 2012	The goal of this project is to provide projections of 21st century landscape change (to year 2100) by expanding the geographic and taxonomic scope of the existing research throughout the SAMBI region and into the Southern Piedmont. This will allow for the development of the core datasets and tools needed for effective Strategic Habitat Conservation (SHC) decision-making across the entire SALCC region. These datasets include projections of climate change, urbanization, ecosystem disturbance processes, land cover (habitat) dynamics and management scenarios; species-habitat models for representative species including habitat affinity models and occupancy models using current and projected future landscape conditions to predict persistence of species under future conditions; and decision support tools using habitat data layers from Regional Gap Analysis and species-habitat models to target and optimize habitat conservation for a single wildlife species, multiple wildlife species using similar habitats or multiple species using multiple habitats in a diverse, dynamic landscape using limited resources.

Manatee protection areas in Puerto Rico.	March 2012	The proposed project is designed to assist the US Fish and Wildlife to identify and provide the scientific basis to propose manatee protections areas in accordance with federal regulations. As such, this project addresses core recommendations made by the U.S. Fish and Wildlife Service 5-year evaluation (USFWS 2007). The expected benefit of this measure is to foster the persistence of the species in the Caribbean through habitat conservation. The proposed project will consist of two phases. The first will be to identify and articulate the fundamental objectives and a portfolio of management options available to the US Fish and Wildlife Service and collaborating conservation agencies. These tasks will be accomplished through a participatory process or workshops. The second phase will consist of synthesis of information, using models when appropriate, to assess the impact of various alternatives and highlight those with most support. The results of this process will be transferred to the US Fish and Wildlife Service for review, decision making and subsequent course of action.	None
Integrated Waterbird Management and Monitoring within the Atlantic and Mississippi Flyways.	December 2012	This project focuses on wetland-dependent migratory birds such as; waterfowl, shorebirds, and wading birds (collectively defined here as waterbirds). Most wetland managers don?t have the luxury of managing for a single species or one guild of species. Managers must take into consideration many factors when targeting management for different bird guilds or conducting management activities that benefit one guild over another. Factors that must be considered are the annual wetland hydrological cycle, species priorities, budget and staff resources, and physical constraints of the wetlands being managed. All these factors lead managers to adjust individual wetland objectives on an annual basis to take into consideration changing wetland conditions that present management opportunities or problems that must be addressed. To meet these needs, habitat and population monitoring protocols and databases will be developed that allow data to be shared or linked across spatial scales, promote the use of adaptive management, and help to identify the importance and priority of management decisions.

American Oystercatcher Conservation Initiative North Carolina	December 2011	The American Oystercatcher (Haematopus palliatus) is an important indicator of ecological conditions on Atlantic coast beaches. Because of its conspicuousness and site fidelity, the oystercatcher is an ideal study species for describing the challenges faced by beach-nesting shorebirds. American Oystercatchers are listed as a “species of special concern” in North Carolina (North Carolina Wildlife Resources Commission 2008) and as a high priority species in the US Shorebird Conservation Plan (Brown et al. 2001), in large part because of threats associated with development and increasing recreational use of coastal breeding and wintering sites. Oystercatcher populations are declining in the mid-Atlantic states, despite rising numbers and expanding breeding range to the north (Mawhinney and Benedict 1999; Nol et al. 2000; Davis et al. 2001). These overall declines have triggered a large-scale, multi-state research effort to understand the bird’s ecology and conservation needs. A study of breeding American Oystercatchers in North Carolina was initiated on South Core Banks, Cape Lookout National Seashore in 1995 to document nesting success (Novick 1996). The scope of the original study has expanded to include all of the islands of Cape Lookout and Cape Hatteras National Seashores. The study of Oystercatcher breeding success further expanded in the state in 2002 and 2003 when the North Carolina Audubon Society initiated nest monitoring on islands in the mouth of the Cape Fear River. Although the undeveloped barrier islands that comprise the National Seashores were thought to be ideal breeding habitat for American Oystercatchers, nest survival was much lower than expected. Novick (1996) attributed low hatching rates to human disturbance. Davis (1999) continued the work on Cape Lookout and used nest monitoring and predator tracking stations to determine the causes of nest failure. She determined that a majority of nests were lost to mammalian predators. Subsequent studies in North Carolina have supported the conclusion that mammals are the primary nest predators, but they also suggested an interaction between human disturbance and nest predation rates (McGowan 2004, McGowan and Simons 2006). McGowan and Simons (2006) found an inverse relationship between the number of visits an Oystercatcher made to the nest and the nest survival rate, suggesting that the more often nests were disturbed the more likely they were to be found by predators. Simons and Schulte (2008) illuminated causes of chick loss and modeled hurricane effects on oystercatcher production. 2009 research objectives included: 1) Continued monitoring of reproductive success of the North Carolina breeding population 2) Continued banding and resight efforts to facilitate mark-recapture analysis Objectives of research for the 2010 season include: 1) Assessing the response of breeding oystercatchers to an experimental removal of raccoons on South Core Banks, Cape Lookout National Seashore 2) Assessing of the response of the South Core Banks raccoon population following the experimental removal to evaluate the feasibility of predator management as a conservation strategy for ground nesting birds and sea turtles. 3) Quantifying of the relative costs of reproduction on traditional ocean-side sites and nontraditional sound-side, river estuary, man-made island, and mainland sites	None
Fishery population and habitat assessment in Puerto Rico streams.	August 2012	Research is underway to obtain more extensive quantitative population estimates for stream fishes of Puerto Rico and their habitat. We then plan to develop a biotic index that may be employed to rate and classify riverine sport fish habitat. We will analyze contaminant concentrations in sport fish, their foods, and habitats to assess environmental effects and consumption risks. And we will conduct research on the ecology and migration of amphidromous sport fishes to better define management units and scale.	None

Interaction of stocked trout with native nongame stream fishes.	April 2011	The goal of this research is to gain an understanding of the interactions between stocked trout and native nongame fishes in the stream environment. Our primary objective will be to quantify changes in fish density, distribution, and habitat use of nongame fishes as affected by the presence of stocked trout. A secondary objective will be to qualitatively assess direct negative interactions between trout and nongame fishes. Results may be used to inform and guide management actions to improve resource management strategies and to educate fishery constituents and the public.	None
Hierarchical landscape models for endemic unionid mussels: building strategic habitat conservation tools for mussel recovery in the South Atlantic Conservation Cooperative	September 2013	To advance strategic habitat conservation for mussels, managers need: a) better quantification of species life-requisites, including habitat suitability; b) models using landscape level attributes as predictors of suitable mussel habitat; c) mussel occupancy predictive models; and d) population biology and habitat-based estimates of the stream network needed to conserve the species.

Assessing mortality, tag reporting rate and movement patterns of Albemarle Sound-Roanoke River striped bass	June 2014	Striped bass, Morone saxatilis, are of high commercial and recreational value in the Albemarle Sound-Roanoke River. Recent assessments of this stock have not included any results from the North Carolina Division of Marine Fisheries (NCDMF) annual striped bass tagging program because of critical unknowns such as the reporting rate of tags. We propose to use a fishery independent approach of passive integrated transponder (PIT) tags to evaluate tag reporting rate by sector (commercial, estuarine recreational, and in-river recreational) in order to analyze the tag return data and estimate seasonal and spatial values of fishing mortality and natural mortality. We also propose to compare the financial costs and benefits of this approach, in order to evaluate the feasibility of including PIT tags in the NCDMF tagging program for striped bass and those of other valuable North Carolina species. If feasible in terms of cost, this approach should make conventional tagging programs much more useful for stock assessment. We propose to use sonic telemetry to get better estimates of natural and hook and line release mortality for striped bass during the spawning run in the Roanoke River. Combined tag return and telemetry data can better estimate spatial and seasonal patterns in natural and fishing mortality rates and in this case, could more specifically address spatial aspects of fishing and natural mortality rates during the spawning season. Using the telemetered fish, we propose to estimate the proportion of adult Albemarle Sound striped bass that enter the Roanoke and Chowan basin rivers annually to better identify overall stock dynamics. Results from this study would improve our understanding of anadromous striped bass biology and mortality rates and lead to more precise stock assessments and better management of this valued population.

Hydroacoustic monitoring of anadromous fishes in the Roanoke River	June 2013	Anadromous fishes spend the majority of their adult lives in the ocean and make yearly migrations (runs) into coastal rivers to spawn. These species are targeted by commercial and recreational fisheries both in the ocean-estuarine environment and during their runs into coastal rivers. Information on abundance of these important species is needed in order to properly regulate harvests and to assess the effectiveness of rebuilding efforts. The primary objective of this study is to estimate the size of spawning runs of American shad, striped bass, and other anadromous species. A related objective is to gain a detailed understanding of migratory behavior in order to design an effective monitoring program and interpret the hydroacoustics data.	None
Movement and spawning of American shad transported above dams on the Roanoke River, North Carolina	June 2010	American shad Alosa sapidissima are in decline along much of their native range as a result of overfishing, pollution, and habitat alteration in the coastal rivers where they spawn. In regulated rivers, dams can limit American shad access to historic spawning sites. One approach to restoration is to provide access to habitat above dams through a trap-and-transport program. We examined initial survival, movement patterns, spawning, and downstream passage of adult sonic-tagged American shad transported to reservoir and riverine habitats upstream of three hydroelectric dams on the Roanoke River, North Carolina and Virginia, during 2007 and 2008, with added data from a separate contracted study in 2009. In 2007 and 2008, average survival to release was 85%, but survival decreased with increasing water temperature. No mortality during transport was observed in 2009. Some tagged American shad released in reservoirs migrated upstream to rivers; however, most meandered back and forth within the reservoir. A higher percentage of fish migrated through a smaller (8,215 ha) compared to a larger (20,234 ha) reservoir, suggesting that population level effects of transport may depend on upper basin characteristics. In addition, more tagged fish released in reservoirs appeared to migrate to riverine habitat during a normal flow year (2009), as compared to drought years (2007 and 2008), suggesting that environmental conditions may affect migration. Transported American shad spent little time in upper basin rivers, but were there when temperatures were appropriate for spawning. No American shad eggs were collected by weekly plankton tow sampling in 2007 and 2008 in upper basin rivers. Estimated initial survival of tagged adults after downstream passage through each dam was 71-100%; however, only 1% of the detected fish migrated downstream through all three dams and many were relocated just upstream of a dam late in the season. Although American shad were successfully transported to upstream habitats in the Roanoke River Basin, under present conditions, transported individuals may have reduced effective fecundity and post-spawning survival, than non-transported individuals.

Advancing climate change adaptation strategies for high elevation and endangered lowland amphibian species in the US Caribbean.	September 2025	We propose to advance effective and efficient adaptation to climate change and recovery in the US Caribbean by addressing two objectives: 1) measuring key micro-climate variables along multiple habitat and climate gradients, allowing for identification of resilient climate habitats for at-risk and endangered amphibian species; and 2) expanding prior work to distinguish between the interactive effects of moisture and temperature on <i>Eleutherodactylus </i>occurrence and abundance. The expected results from this study include an island-wide evaluation of potential climate <i>refugia</i> sites for temperature and moisture sensitive <i>Eleutherodactylus</i> species, and criteria for decision makers to determine when and where they should engage in in-situ management or managed translocations.	The well-known <i>coquí</i> frogs, represented by 17 species in the genus <i>Eleutherodactylus</i> in Puerto Rico, are threatened by extreme heat and drying, and coastal saltwater intrusion.

American Alligator Ecology in North Carolina	December 2024	North Carolina is the northern range limit for American alligators in the US, creating unique challenges related to alligator conservation, monitoring, and management. Given their range limit, the North Carolina Wildlife Resources Commission developed an alligator monitoring program to track changes in alligator distribution. This project analyzes alligator data to estimate occupancy and relative abundance via spotlight surveys and evaluates the ability of spotlight surveys to provide adequate information for monitoring programs. This project is a collaboration of researchers across multiple agencies and includes North Carolina State University, USGS North Carolina Cooperative Fish and Wildlife Research Unit, and the North Carolina Wildlife Resources Commission. Results of this work provide an evaluation of current alligator monitoring efforts in North Carolina (spotlight surveys, mark-recapture methods) and the development of approaches that can extend to regional- and statewide alligator research and management programs in North Carolina.	The goal is to analyze and evaluate currently available alligator data to estimate occupancy and relative abundance via spotlight surveys, evaluate the ability of spotlight surveys to provide adequate information for monitoring programs, and investigate approaches to estimate demographic rates and abundance using a case study of an intensively studied alligator population at Lake Waccamaw.

Connectivity for a Complex Life Cycle: Conserving the Crystal Skipper Butterfly in a Coastal Urban Environment	April 2026	Understanding of how organisms with complex life cycles interact with fragmented habitats and changing environments has important climate mitigation implications. The Crystal skipper (<i>Atrytonopsis quinteri</i> Burns) is a small butterfly that was described as a new species in 2015 and occurs only on a 50 km stretch of barrier islands on the North Carolina coast that is subject to numerous risks from climate change and urbanization. Our project will: (1) Develop a rigorous, sustainable, and unbiased survey methodology to document skipper population sizes and monitor trends, (2) Evaluate the role of landscape-scale nectar connectivity in limiting skipper populations, and (3) Assess whether management can increase Crystal skipper populations and offset effects of climate change. The project is a collaboration of researchers across multiple agencies and includes North Carolina State University, USGS North Carolina Cooperative Fish and Wildlife Research Unit, and the North Carolina Aquarium. Results from this work will inform the implementation of adaptive, robust, and strategic improvements to the existing conservation plan for this species of conservation concern.

Incorporating estimates of detection probability into the Breeding Bird Survey protocol: Assessment of current sampling methods	December 2011	The goal of this research is to evaluate the relative costs and benefits of incorporating different methods of estimating detection probability into the Breeding Bird Survey protocol. Researchers propose to implement this assessment within the operational framework of the BBS through close collaboration with national BBS coordinator, Keith Pardieck, North Carolina BBS coordinator, Mark Johns, and numerous North Carolina BBS volunteers who have participated in our detection probability experiments over the past three years. 1) Researchers propose to sample a minimum of 50 of the approximately 80 North Carolina BBS routes over three consecutive breeding seasons. 2) They will compare results derived from unadjusted unlimited-radius counts with those derived from counts adjusted for detection probability using, multiple observer, time of detection, distance sampling, and repeated count methods. 3) They will provide BBS program managers with practical recommendations about the relative costs (personnel, sampling effort, training) and benefits (bias reduction) of incorporating different measures of detection probability into the BBS protocol. They anticipate that this research will provide field biologists and natural resource managers with a clearer understanding of the bias and precision of current point count sampling methods. The primary products will include measures of uncertainty associated with current point count methodologies and an assessment of the improvements expected if additional information needed to estimate detection probabilities is collected. Benefits will include new applications of theory and sampling methodologies that will result in practical improvements in the quality and scientific credibility of Breeding Bird Survey census data. Subject to the availability of additional funding, anticipated follow-on products include training workshops for practitioners and monitoring program managers, and a monograph synthesizing the results of detection probability experiments and providing recommended sampling protocols for specific research, monitoring, and management objectives	None
Ecology of raccoons within Cape Lookout National Seashore, NC, and the efficacy of raccoon removal as a management tool for protecting rare, threatened, and endangered species	June 2011	To date, relatively little published scientific information is available on raccoon populations inhabiting Atlantic barrier islands, suggesting that additional research is warranted. Although removal of predators like raccoons is still carried out at some sites (e.g., national wildlife refuges) to protect T&E species and is listed as a viable action in the recovery plans for some T&E species, the long-term efficacy of the technique remains questionable. In this study, researchers propose to gather basic ecological data on raccoons on South Core Banks, Cape Lookout National Seashore (CALO) (e.g., home range size, movement patterns, demographics), remove some raccoons from the population, and assess the effects on the ecology of the remaining population and the response of nesting sea turtles and shorebirds. The intent of the removal work is three-fold: 1) determine if the incidence of predation on T&E species declines post-removal, 2) determine the extent and timing of future predation events from areas where raccoons were removed, and 3) assess the impact of removal of raccoons on another prey species (e.g., ghost crabs). Finally, as part of this effort researchers will recommend a science-based management plan and a monitoring protocol that will allow the NPS to measure changes in the distribution and abundance of raccoons at Cape Lookout National Seashore. Objectives: The objectives of this project can be placed into two broad categories: understanding raccoon ecology on coastal islands and understanding the efficacy of raccoon removal as a tool for managing threatened and endangered sea turtles and ground-nesting shorebirds and terns. Research will involve an evaluation of basic raccoon ecology by identifying rest areas, den and nest sites, and local movement patterns, and by estimating key demographic rates such as age-specific survival and fecundity. Researchers will also evaluate how removing raccoons from this environment affects the abundance and productivity of endangered and threatened prey species and ghost crabs, and the ecology of raccoons that remain in the system. They will accomplish this by initiating a program to monitor T&E species abundance and productivity after raccoon removal, and by initiating a program to monitor the response of the reduced raccoon population and the response of non-target prey.

We will also evaluate uncertainty with respect to use of this information for scaling down of global cuirculation models. (2) Link wildlife habitat models developed in objective (1) to outputs from models simulating the response of intertidal wetland complexes in the northeast to predicted sea level rise. This information will be provided by USGS Patuxent researchers	None
Assessing the relationship between acid precipitation, calcium depletion, and avian productivity in Great Smoky Mountains National Park	September 2010	The primary objectives of this research are revised to: 1. Quantify the effects of acid deposition and subsequent thresholds of calcium depletion on the reproductive success of high elevation songbirds and the diversity and abundance of terrestrial snail populations in the southern Appalachians. 2. Determine the level of threat of mercury bioaccumulation in high elevation breeding songbirds and terrestrial snails in the southern Appalachians. Explanation: Research Objective #2 has been added because it has recently been determined that mercury (Hg) and methylmercury (MeHg) are important contaminants of wildlife populations. Inorganic mercury enters aquatic systems via atmospheric deposition where it is chemically converted to MeHg, a biologically active and toxic form. Recent research has shown that MeHg bioaccumulates through the aquatic foodweb from plankton, to invertebrates, to fish, and then to piscivorous vertebrates. Although recently there has been much improvement in understanding the mechanisms of mercury transfer and accumulation in freshwater aquatic systems, little is known about its role in the terrestrial system. Upland forest soils are natural sinks for atmospherically deposited mercury because the majority of mercury binds to organic and mineral soil particles. Mercury is concentrated primarily in the upper soil column. Research indicates that up to 60% of Hg that reaches lakes originates from the terrestrial watershed. Mercury loading is significantly higher in evergreen compared to deciduous habitats, and higher (2-5x) in mountainous areas in the northeastern United States compared to nearby low elevation areas. Consumption of contaminated food is the primary risk of mercury exposure to terrestrial vertebrates. Birds are at particularly high risk to mercury toxicity because many species are at high trophic levels, are long-lived, and are vulnerable to neurological and reproductive impacts from elevated Hg levels. The effects of mercury contamination in birds has been primarily studied in large migratory birds, wading birds, shorebirds, and raptors; few studies have addressed these issues in passerines, especially those species not associate with aquatic systems. In a multi-species analysis of mercury contamination, piscivorous birds were repeatedly shown to have some of the highest MeHg levels of the 38 species analyzed, however insectivorous birds in both aquatic and terrestrial habitats were also found with elevated levels. Although little research has focused on effects of mercury in passerines, in 2005 Rimmer et al. hypothesized that among terrestrial birds mercury contamination poses the highest risk to obligate insectivorous species. Rimmer found that blood mercury levels in Bicknell's Thrush (Catharus bicknelli) were correlated with Hg levels in leaf litter, demonstrating that dietary MeHg uptake occurs in passerines inhabiting terrestrial environments unassociated with standing water. Mercury accumulation in nestling Prothonotary Warblers (Protonotaria citrea) was also correlated with soil mercury concentrations around the nest. Rimmer further demonstrated that blood Hg levels in Bicknell's Thrush overlapped with those of Bald Eagles, indicating equivalent trophic status of a terrestrial-based insectivore with an aquatic-based piscivore. Rosten et al. found that resident insectivorous passerine species at contaminated sites in Europe accumulated higher mercury loads in eggs and nestlings than migratory or seasonal species. Although Bishop et al. claim that nestling birds are the best indicator of local contaminant trends, mercury levels in adult resident birds can also demonstrate chronic effects due to bioaccumulation. One limitation with the Rimmer et al. study is that they examined mercury levels in Neotropical migrants, and were thus unable to study chronic effects of mercury in resident adults. In birds, mercury loads are often sampled in specific organs, blood, or feathers, with mercury accumulation seen regardless of the material examined. Although adult females can reduce body burdens of mercury during egg production, depuration of MeHg most commonly occurs during feather growth, as MeHg binds strongly to keratin. Virtually all Hg in a feather is MeHg and reflects blood Hg levels at the time of molt. Because an acidified environment both enhances methylation of mercury and depletion of calcium, the adverse effects of acid precipitation may be complex. A recent study showed that Pied Flycatchers (Ficedula hypoleuca) were more sensitive to decreased levels of calcium-rich prey (i.e. snails) in a heavy-metal-polluted area. Thus, there is a pressing need to understand whether atmospheric pollution is contributing to both calcium limitation and mercury toxicity in southern Appalachian high elevation communities. The high elevations of Great Smoky Mountains National Park continue to report some of the highest rates of deposit of air-borne nitrate and sulfate in eastern North America. One effect of this well documented acidification is the loss of calcium, which is an essential element to most life. Observational and experimental studies in highly acidified sites in northern Europe have shown that losses of environment calcium are linked to reductions in populations of songbirds which depend on snail shell calcium for egg production. Similar research has not been conducted in the U.S., but it is necessary to assess the widespread effects of acid deposition on terrestrial animals. Researchers will use the Black-capped Chickadee as a model for evaluating the effects of acid precipitation on high elevation bird communities in the southern Appalachians. Black-capped Chickadee populations have been declining in the southern Appalachians over the past two decades, and they have disappeared as breeders from several high elevation sites where they once occurred. Objectives: (1) Assess whether Black-capped Chickadees nesting at high elevations in Great Smoky Mountains National Park are suffering from acid rain related calcium limitations during the breeding season. (2) Determine the sources of calcium for Black-capped Chickadees breeding at high elevations in the Park. (3) Determine if calcium limitation affects the behavior, habitat use, or breeding success of adult birds	None
Modeling the response of imperiled freshwater mussels to anthropogenically induced changes in water temperature, habitat, and flow in streams of the southeastern and central United States.	December 2012	Freshwater mussels possess a suite of traits that may make them highly vulnerable to climate change. These traits include their patchy distribution, phenological traits (i.e., spatial and temporal dependence of their larvae on host fish), limited dispersal, limited mobility, their threatened status, and the fact that they inhabit fragmented landscapes. Recent research in our laboratory has determined that some freshwater mussel species are already living close to their upper thermal tolerances and thus, may be at risk from increasing surface water and bed sediment temperatures and altered flow regimes due to climate change and associated fluctuations. A primary objective of this project will be to use our newly developed mussel vulnerability and risk threshold data in downscaled watershed and instream regional models so that federal and state natural resource managers will be able to forecast species responses to climate change over the next 30-50 years and to develop adaptation strategies to mitigate the adverse effects. Secondary objectives will be to refine these models and to generate new models with empirical data produced from integrated laboratory and field studies of mussel temperature sensitivities in water and sediment, and instream flow and habitat assessments for mussels. - Evaluate the relative sensitivity of juvenile native freshwater mussels to a range of common and extreme water temperatures that may be encountered during summer periods in streams in the southeastern and central United States by conducting water-based laboratory tests with species that represent each of the two major subfamilies (Ambleminae and Unioninae) of mussels. These tests are necessary to expand the data base for temperature suitability for native freshwater mussels; - Develop a method for conducting temperature tests with juvenile mussels and sediments. This task will utilize for guidance the recently approved standard method for conducting water-only toxicity tests with early life stages of freshwater mussels (ASTM 2006), but will standardize the sediment variables (e.g., particle size, organic content) that may influence temperature exposures. These tests will be conducted with juvenile mussels and are necessary to provide an accurate and precise test method. This task will address the issue of whether sediments may provide a partial thermal buffer for mussels in their native stream habitat; - Evaluate the relative sensitivity of juvenile native freshwater mussels to a range of common and extreme sediment temperatures (with and without overlying water) that may be encountered during summer periods in dewatered streams in the southeastern and central United States by conducting laboratory tests (using the method developed in Objective 2) with species that represent each of the two major subfamilies (Ambleminae and Unioninae) of mussels. These tests are necessary to expand the toxicity data base for temperature-based suitability for native freshwater mussels and will directly compare sediment temperature sensitivities to those already established in Objective 1 above and from our previous research (Pandolfo 2008) for water-only temperature sensitivities. This task will address the issue of whether sediments may provide a partial thermal buffer for mussels and ties directly to related research addressing instream habitat conditions for survival of mussels; - Sample common and imperiled mussel occurrences and associated microhabitat parameters, including temperature and flow, in one Atlantic Slope river basin to develop empirical models explaining mussel occurrence and abundance and field threshold values; - Synthesize all of the stream model and mussel temperature sensitivity, physiology, habitat, and community composition information for biologists and others involved with management of aquatic species and environmental quality.

Migratory behavior of diadromous fishes in the Roanoke River, NC	June 2011	Diadromous fish species such as striped bass Morone saxatilis, American shad Alosa sapidissima, blueback herring A. aestivalis, and American eel Anguilla rostrata are ecologically, economically and historically important (Walburg and Nichols 1967; Garman 1992; Garman and Macko 1998; Limburg et al. 2003). Several of these species historically supported large commercial fisheries along the Atlantic coast and in North Carolina specifically, but most of these fisheries declined during the nineteenth century (Walburg and Nichols 1967; Hightower et al. 1996; Richards and Rago 1999; Limburg et al. 2003). The declines are likely a result of overfishing, construction of dams, land use change and poor water quality (Walburg and Nichols 1967; Rulifson 1994; Hightower et al. 1996; Cooke and Leach 2003; Limburg et al. 2003). Dams have contributed to the decline of diadromous species by blocking migration routes to historical spawning and nursery locations and altering downstream habitat (Rulifson and Manooch 1990; Rulifson 1994; Pringle et al. 2000; Trush et al. 2000; Dauble et al. 2003; Freeman et al. 2003). Flow in the Roanoke River basin within Virginia and North Carolina was unregulated until 1950, but six dams now regulate flow (Rulifson and Manooch 1990; Walsh et al. 2005). The Roanoke Rapids dam, located at rkm 221, is the lowest dam on the river. It was completed in 1955 for hydroelectric power generation and replaced a small dam that had been present in the same location since about 1900 (Rulifson and Manooch 1990; Hightower et al. 1996; Hightower and Sparks 2003). Neither dam included provisions for fish passage, thus rkm 221 is the extent of upstream migration for diadromous fishes. Several studies conducted by the NC Cooperative Fish and Wildlife Research Unit have examined migration and habitat use, in order to better understand how upstream dams might be affecting anadromous fishes. One current study uses hydroacoustics to examine migration timing and abundance for hickory shad, American shad, and striped bass (NCSU project 5-23061). Preliminary results indicate that the method can be used to count upstream migrants and to obtain detailed information about spatial and temporal patterns of migration. Results of the hydroacoustic study will be important for management, once the reliability of the estimates has been validated. For example, the estimates of American shad run size will be used to guide a restoration program for American shad. This program includes a plan to trap and transport adult American shad above three dams, into the upper part of the basin where additional spawning habitat is located. The start of the trap-and-transport program depends on when the hydroacoustic estimates of run size reaches a trigger value (3-year average of 20,000 individuals). This current project is intended to complement the existing hydroacoustic study, in order to allow for improved estimates of run size, in total and for individual species. This supplemental funding will improve estimates of species composition, and will support experimental work relating fish size and species to acoustic variables. A long-term goal is to determine whether acoustic variables measured for individual fish tracks (e.g., average target strength, time in beam, tortuosity) can be used to discriminate among species.

Assessing benefits to migratory fishes of habitat restored by dam removal	August 2011	Many fish species migrate in order to reach suitable spawning or nursery habitat. All of these groups benefit when access to additional habitat is restored by dam removal. The Little River basin in North Carolina provides a valuable opportunity to examine how migratory fishes use habitat restored through dam removal. One problem in predicting the benefits of dam removal is that relatively little is known about how these fishes select spawning habitat (e.g., whether species use tributaries or mainstem rivers, deep versus shallow sites, or different substrates). Another limitation in predicting benefits of dam removal is that habitat preferences are poorly understood. Specific project objectives are: to determine fish abundance and migratory patterns during spring and to relate movements to physical variables including habitat availability. Information on spawning habitat will be used to develop refined models for predicting the benefits of fish passage or dam removal in other systems	None

Field validation of king rail habitat models in the Roanoke-Tar-Neuse-Cape Fear ecosystem	May 2011	1) Conduct King Rail surveys across 100 wetlands in the Roanoke-Tar-Neuse-Cape Fear Ecosystem, with three visits per site, following procedures outlined in the Standardized North American Marsh Bird Monitoring Protocols. 2) Conduct King Rail surveys across 100 wetlands in the Roanoke-Tar-Neuse-Cape Fear Ecosystem, following procedures outlined in the Standardized North American Marsh Bird Monitoring Protocols in spring 2007 and 2008. Objectives will be achieved by recruiting three field crews of two individuals each working through the breeding seasons of 2008 and 2009. On the basis of standardized NA Marsh Bird Monitoring Protocols, the crews should be able to survey approximately100 sites, with three visits per site. Final composition of the 100 sites will be driven by (1) the strength of the remotely-measured explanatory variables in the theoretical models, (2) the need to validate the model at ecosystem and refuge spatial scales, and (3) the need to validate model predictions across the full range of detection probabilities.

Development and Dissemination of High-Resolution National Climate Change Dataset.	September 2012	We propose to create a comprehensive web-based dataset of high-resolution climate change projections that can be used to assess the impacts of climate change on ecosystems in the continental United States. The dataset will be generated by applying advanced statistical downscaling methods to a comprehensive selection of global climate model simulations from the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) database. To meet this objective we will hold a series of facilitated workshops to solicit input and disseminate information from researchers involved with the National Climate Change and Wildlife Science Center (NCCWSC). We will hold two workshops in FY2010 and a final, follow-up workshop in FY2011. The first workshop will involve researchers from funded NCCWSC proposals and other key stakeholders from DOI agencies. Participants will describe how downscaling approaches are used in their work and provide feedback on useful climatic variables relevant to ecosystem modeling efforts. In addition, the workshop will be an opportunity for participants to learn about different downscaling methods, global climate models, best practices for use of climate data (both observations and model output) and the structure of the proposed national downscaled climate dataset. We plan to hold this workshop in late winter 2010. A second workshop at the '3rd USGS All Modeling Conference' in Denver (June 2010) will consist of a half-day short course on global climate models, downscaling techniques, and the planned Geo Data Portal (GDP). We will hold a final workshop with potential data users in late 2010 or early 2011 to evaluate the proposed design of the GDP. These workshops will improve our final deliverables but also improve knowledge within the USGS and DOI community about climate change science and climate change scenarios.	None

Adaptive management of horseshoe crabs and shorebirds in Delaware Bay: Predictive Modeling and Implementation	December 2010	Science-based management of horseshoe crabs and shorebirds bears directly on national and regional conservation priorities, specifically the USFWS Strategic Habitat Conservation Initiative, the DOI Adaptive Management Initiative, and proactive species conservation to preclude listing under the Endangered Species Act. This project contributes to meeting high-priority needs in the National Shorebird Plan, BCR 30 Draft Plan, DE State Wildlife Action Plan, and NJ State Wildlife Action Plan. Objectives: (1) develop multi-species predictive models that link horseshoe crab and shorebird dynamics to management alternatives; (2) evaluate the models by comparing to historic data and evaluating the underlying assumptions; (3) predict consequences of a set of management alternatives that are relevant to current management decisions; (4) use these models to identify state-dependent management action that are optimal with respect to specified objectives; and (5) report and interact with a working group of horseshoe crab and shorebird experts and stakeholders who are collaborating on adapive management.

SARS-CoV-2 at the human–wildlife interface: Understanding wildlife as potential reservoirs for COVID-19 across urban-rural gradients	February 2023	SARS-CoV-2 is a highly transmissible and pathogenic coronavirus that has led to the COVID-19 pandemic. While vaccines and drugs are reducing mortality rates, the impacts of the virus may persist long-term, especially if non-human reservoirs for the disease create permanent sources of human infection. SARS-CoV-2 antibodies have been documented in numerous wildlife species in North America (e.g., white-tailed deer, rabbits, ferrets); however, it is unclear how prevalent SARS-CoV-2 is across wildlife species and regions, and whether wildlife can transmit SARS-CoV-2 to humans and domestic species. Understanding the prevalence of SARS-CoV-2 in wildlife and how prevalence rates vary across the human-wildlife interface is critically important to evaluate the maintenance and transmission of COVID-19. We are capturing and testing white-tailed deer in North Carolina to investigate SARS-CoV-2 prevalence and the predictors of SARS-CoV-2 across an urban–rural continuum. White-tailed deer are a particularly relevant study species because they are abundant in landscapes as diverse as rural forests and suburban neighborhoods and high prevalence of SARS-CoV-2 antibodies (>30%) is documented in other regions of North America. Our proposed study will provide seed data for future proposals that expand these concepts to consider SARS-CoV-2 prevalence across multiple species (e.g., mice, raccoons, coyotes, pets), spatial scales (within and beyond North Carolina), and the socio-economic factors affecting transmission risk.

Implementation of National Biogeographic Data and Analyses Toward a National Assessment.	September 2025	The USGS North Carolina Cooperative Fish and Wildlife Research Unit (NCCFWRU) has an ongoing partnership with the federal government on developing, analyzing and implementing Gap Analysis datasets starting with the NC-GAP Project in 1996 up through to the first completed data set for the contiguous United States in 2016. The focus of the next phase of effort will be in three areas: development of analyses to better understand the state of national biodiversity of aquatic and terrestrial communities, refinement of our data infrastructure to allow seamless updates of data products, and continued development of outreach tools to better facilitate the implementation of our data in conservation assessments. Additional research efforts will incorporate species occurrence data to assess and inform predicted distributions, assess the impact of dam removal on fish communities, incorporate Forest Inventory and Analysis plot data in the refinement of habitat availability, map patterns of species’ turnover and identify common drivers of habitat quality across terrestrial and aquatic vertebrate species.

Determining Henslow's Sparrow (Centronyx henslowii) population redundancy in North Carolina.	December 2024	Henslow’s Sparrow (HESP) is a grassland specialist, migratory songbird with a rapidly declining habitat range due to habitat loss and climate change. The species is a conservation priority for the State and US Fish and Wildlife Service due to its limited presence in North Carolina and declining populations across the United States. In North Carolina, the species’ stronghold is at the Voice of America Game Lands (VOAGL). Ongoing efforts are designed to estimate its population size and assess its response to fire management (resiliency), and determine its genetic distinctiveness (representativeness) from other populations. However, little is known about the sparrow’s presence and abundance in North Carolina outside of the VOAGL. The work proposed herein is designed to: 1) identify the presence or absence of Henslow’s Sparrows at sites with suitable habitat parameters, but where their presence or status is unknown; and 2) develop an accurate habitat range model for Henslow’s Sparrows in the state of North Carolina. This work is important because the existence of other populations would spread the risk of local extinction, and strengthen the bases for strategic habitat conservation plans to protect or co-managed occupied habitat.

Resolving Taxonomic Uncertainty in Caribbean Skink Species	December 2023	In 2014, the USFWS was petitioned to evaluate nine species of Caribbean skinks (<i>Spondylurus </i>spp.) for listing under the U.S. Endangered Species Act. Information on Caribbean skink distribution and ecology is extremely limited, and there remains the possibility that some species may already be extinct. Additionally, taxonomic uncertainty exists across <i>Spondylurus </i>spp., as the genus was reclassified and split into multiple species in 2012 based on analyses of museum specimens. Research to support a Species Status Assessment is therefore needed to (i) resolve taxonomic uncertainty in this species complex and (ii) document skink presence, characterize morphology, and document the distribution of age-classes at island-level scales. This information is critical to evaluating the listing status of these species and future efforts investigating population viability and extinction risk.

Conservation status and management of Henslow's sparrows at the VOA Game Land and eastern North Carolina.	June 2023	We propose four research objectives to deliver a status assessment and gather foundational dataat multiple scales to enable the NCWRC to enhance the persistence of the sparrow at theVOAGL and the State. At the local level, we propose to estimate the sparrow’s capacity tosustain themselves, and quantify the sparrow’s response to habitat management at the Voice ofAmerica Game Land site. The latter is particularly important to lay a foundation for an adaptivemanagement framework to guide habitat management. At the landscape level, we propose towork closely with the North Carolina Bird Atlas project personnel to survey habitats outside theVoice of America Game Land, and lastly, determine the genetic distinctiveness of the NorthCarolina population not addressed by Ibargüen (2004). Off-site surveys are justified tostrengthen the bases for strategic habitat conservation plans to reduce risks of extinction.Likewise, understanding the evolutionary history and genetic connectivity of the North Carolinapopulation of C. henslowii is essential to assess their persistence potential by establishing if theNorth Carolina population is effectively isolated, or subject to “rescue effects” by a broader poolof post-wintering birds from other parts of the species range.

Strategic habitat conservation and adaptive strategies for recovery and pre-listing conservation of Eleutherodactylus (coqui) amphibians in Puerto Rico.	September 2022	The U.S. Fish and Wildlife Service and the Puerto Rico Department of Natural and Environmental Resources want to develop a plan of actions to help the recovery of two endangered species in the genus <i>Eleutherodactylus</i> (commonly known as “coqui”), while also reducing the risk that 14 other coqui species are added to the Endangered Species list. Our multi-disciplinary research team responded by developing foundational environmental and ecological knowledge required to build a robust strategy. To date, we have identified factors influencing where species occur, their abundance, and key drivers of reproduction<sup> </sup>influenced by two major sources of environmental change—climate and land use change—for three representative species (<i>E. wightmanae, E. britonni, </i>and<i> E. antillensis</i>). For this next research stage we propose to: 1) characterize the ability of the three representative species plus the endangered <i>E. juanriveroi,</i> to cope with environmental stresses (i.e. their <i>adaptive capacity</i>) using a combination of laboratory and field experiments, 2) map the genetic structure of these species to learn about connections between different populations and identify centers of genetic diversity, and 3) assist agencies in the development of conservation strategies centered on two potential adaptation actions: species relocations to new habitats (i.e. translocations) and making connections to climate-resilient habitats. By investigating the most effective ways to carry out translocations, we will help decision makers answer WHEN it is best to begin consideration of translocations versus continuing to manage at existing locations. And by investigating which habitats have the potential to be resilient in a changing climate, we will help decision makers answer WHERE the best ‘areas of conservation interest’ would be for translocated individuals. Ultimately, our methods will be applicable to other environmental change settings in the context of developing recovery plans and for helping to prevent the listing of species.	The U.S. Fish and Wildlife Service and the Puerto Rico Department of Natural and Environmental Resources want to develop a portfolio of actions to enhance the status of 2 endangered species and prevent the listing of 14 species in the genus <i>Eleutherodactylus</i>, commonly known as “coqui.” To respond to this need, we developed a multi-disciplinary project aimed at gaining foundational knowledge to build a robust, well-informed adaptive conservation strategy. To date, we have identified factors influencing where species occur, their abundance, and what influences their reproduction<sup> </sup>in the context of two major sources of environmental change—climate (altitudinal gradient) and predominant land uses—for three representative species (<i>E. wightmanae, E. britonni, </i>and<i> E. cochranae</i>). Finally, as a precursor and illustration of the endpoint of the project, we constructed a decision framework for the conservation of <i>E. juanriveroi</i>, one of the two endangered species. Herein we propose to: 1) elucidate the adaptive capacity of the representative species, including <i>E. juanriveroi,</i> to cope with environmental stresses using laboratory (<i>terraria</i>) experiments and develop translocation protocols, 2) ascertain the genetic structure of the aforementioned species to gain insights about connectivity and identify centers of genetic diversity, and 3) frame a conservation strategy centered on two classes of adaptation actions: translocations/introductions and climate refuges. The strategy will enable decision makers to address the temporal and spatial components of recovery and pre-listing efforts. By incorporating translocations/introductions, decision makers address the question of WHEN to invest in <i>in-situ</i> management as opposed to translocations/introductions. The second component help guide decision makers to determine WHERE to translocate/introduce individuals, effectively informing decisions about strategic habitat conservation by creating scenario maps, a list of candidate “areas of conservation interest” that could serve as introduction sites and climatic <i>refugia</i> to enhance recovery/delisting of endangered species or prevent listing of at-risk species.
Estimation of US Atlantic Red Snapper Abundance	August 2023	Previously collected trap and video data, along with ROV survey data, will be used to estimate red snapper abundance within an integrated population modeling framework. Population models require spatial replication over the study area of interest and temporal replicates that are independent but close enough in time to ensure population closure. The proposed study would use trap and video count data to estimate detection probability and abundance of red snapper with an integrated populaiton model fitted in a Bayesian framework. Covariates that influence red snapper detection probability and abundance will be used to predict abundance (with associated uncertainty) at habitats that are similar to SEFIS sampling sites but not sampled. We will conduct workshops with reef fishery stakeholders to assist with identification of non-sampled hard bottom habitats. Based on past work, covariates important to red snapper abundance are likely to include bottom temperature, depth, latitude, and substrate type. A key question with this work is the spatial area that an individual SEFIS trap and video station effectively samples. Recently, project collaborators measured the response of red snapper around baited traps using fine spatial scale telemetry data, and response distance information will be used to estimate the sampled area at trap stations. Red snapper densities derived from ROV surveys will also be estimated at habitat types generally not sampled by SEFIS. Spatial maps of important covariates and habitat type will be used to generate abundance by area across the study region. These individual abundance values would be summed to estimate abundance of red snapper (with associated uncertainty) in the US Atlantic.

Deer Ecology Across an Urban-Rural Continuum	December 2025	Urban/suburban areas continue to spread into rural areas, increasing the need to understand deer ecology and assess the cultural impacts of deer and deer hunting across the urban-rural continuum. The North Carolina Wildlife Resources Commission (NCWRC) is faced with an increased number of interactions between humans and deer in areas of high human and/or deer density, and these interactions often have negative outcomes (e.g., vehicle collisions). There is limited understanding across this continuum of public perceptions and desires of deer and deer hunting, along with little data on deer movements, density, recruitment, survival, and causes of mortality, or how hunting (the primary herd management tool) affects deer populations. Additionally, harvest and survey trends used to monitor herds across county or management zones are confounded by unknown hunter effort and success in these expanding urban/suburban areas. This project aims to increase understanding of spatial and temporal variation in white-tailed deer ecology across an urban-rural continuum in North Carolina and how harvest regulations affect white-tailed deer herds across these landscapes. Results will be available to help evaluate current NCWRC programs (Urban Archery Season, Community DMAP, depredation permits) and adjust or create new programs. Information can also be used to provide technical guidance to municipalities, landowners, and hunters. Results will be applicable to areas across the state and will have implications for other urban-rural areas across the state and country.

Habitat Characteristics of Bear-Vehicle Collision Kill Sites, Bear Family Group Dynamics and Source-Sink Dynamics for Black Bears in Urban Environments and the Implications for Regional Black Bear Population	December 2022	Cities now constitute one of the most rapidly growing ecosystems in the world, and with the global spotlight on increasing urbanization and development, the focus on wildlife in ‘natural’ systems is sharing importance with a focus on wildlife in urban systems, providing unique research opportunities in ecology and conservation. Currently, greater than 10% of the earth’s land surface is categorized as ‘urban cover’ and that area is continually growing. By 2050, 70% of the human population is expected to live in cities, which now constitute one of the ‘newest and fastest growing’ ecosystems in the world. In North Carolina, black bear populations occupy nearly two-thirds of the state and their range continues to expand, including into areas with high densities of people and road networks. Humans and black bears are now living in greater proximity to each other, resulting in increased human-bear interactions and some areas of the state may have reached or exceeded the social carrying capacity. Continued investigations into the fine–scale spatial and behavioral ecology of black bears in urban environments is warranted. For example, the identification of characteristics associated with bear-vehicle mortality along major interstates will help identify habitat characteristics associated with collision, and thus may aid in reducing collisions with vehicles. Additionally, in source-sink dynamics, wildlife populations that have access to high quality habitat typically have birth rates that are greater than death rates and surplus individuals disperse from the population as emigrants. In contrast, sink populations have low habitat quality, or suitability, and thus experience death rates that exceed birth rates and the population could decline towards extinction (i.e., a sink), unless ‘rescued’ by immigration from surrounding source populations. We will evaluate family group dynamics and estimate population growth rates and population dynamics. Clearly, these objectives have direct and indirect consequences for humans and bears in our rapidly changing urban environments.

Advancing the knowledge of freshwater mussel conservation: examining the role of manganese on recent mussel die-offs and enigmatic declines	May 2023	The Southeastern and Mid-Atlantic regions of the United States contain the greatest biodiversity of native freshwater mussels in the world, but they are highly imperiled due to habitat alteration and destruction, pollution and poor water quality, and the introduction of aquatic invasive species. Over recent decades, U.S. Fish and Wildlife Service and state fish and wildlife management agency biologists have responded to an increased frequency of mussel die-offs, enigmatic declines, and problems with decreased mussel growth and survival, but a definiticve cause has yet to be identified. However, a recent, but unexplained relation has been identified between manganese (Mn) concentrations and several of these mussel decline and die-off events. Therefore, we propose to examine the toxicity of Mn to mussels in controlled laboratory tests with captively propagated larval and juvenile mussels and with adult mussels collected from low Mn-containing streams. We will then compare these findings to mussels and Mn concentrations in water and sediment from streams where die-offs and declines have occurred. This high impact project focuses on native freshwater mussel conservation priorities of the Southeast region and potentially nation-wide. The project has direct links to the strategic science needs of the natural and cultural resource managers in the region and beyond, because it addresses specific priorities outlined in the State Wildlife Action Plans for the conservation of native freshwater mussels in the States of North Carolina and Virginia and federal at-risk molluscan species in Region 4 and Region 5 of the USFWS and others across the country. In addition, this project will have direct relevance and benefit to other federal resource management and research agencies, such as the U.S. Environmental Protection Agency, who utilize the mussel toxicity data in water quality criterion development. The completion of these research objectives will provide natural resource managers and other decision makers with real-world exposure and survival scenarios and would directly impact the recovery plan for the endangered Appalachian Elktoe mussel by informing the potential causal mechanisms for its die-off and decline in the Little Tennessee River of North Carolina. The persistence of all freshwater mussels will be addressed in the scope of the project.

Impacts of sea level rise and associated salinity changes on at-risk native freshwater mussels and their habitats in Atlantic coastal rivers	December 2022	The Southeastern and Mid-Atlantic regions of the United States contain the greatest biodiversity of native freshwater mussels in the world, but they are highly imperiled due to habitat alteration and destruction, pollution and poor water quality, and the introduction of aquatic invasive species. Now they are at even greater risk from the stresses associated with climate change induced sea level rise and its associated changes in salinity, temperature, and stream flow. In this project, a unique opportunity exists to investigate the potential adaptation and vulnerability of a native freshwater mussel, the Tidewater Mucket, in these coastal river systems and offer solutions for its conservation. We have recently discovered a population of these mussels in a reservoir along the North Carolina-Virginia border that have been isolated from their native riverine habitat and associated natural fluctuations in salinity for over 50 years. These mussels have apparently adapted to the relatively high temperatures, low flow, and low salinity of a reservoir environment, whereas their native counterpart populations of Tidewater Mucket in the downstream portions of coastal rivers that have adapted to withstand small but periodic exposures to salinity and altered flows are declining. Our federal and state natural resource management partners, policy makers, and other stakeholders would like to know how these native coastal plain mussel populations will respond to larger and longer durations of salinity incursions like those predicted with sea level rise. In this study, we will use mussels from both the reservoir and riverine populations to understand their vulnerability to salinity by conducting sensitivity tests under controlled laboratory conditions, determine the potential effects of natural riverine salinity gradients by conducting a transplant experiment, and develop risk-based visualization maps of mussel salinity tolerances in existing occupied habitats incorporating predictions in sea level rise and projected salinity ranges. The outcomes of this research will provide actionable management and conservation information for maintaining these highly imperiled, but valuable molluscan resources.	The freshwater aquatic organisms that inhabit rivers, especially those that reside in coastal drainages live in constrained corridors. Thus, populations can only move and adapt to changing environmental conditions in a longitudinal manner (upstream to downstream or downstream to upstream). Many of these organisms have evolved and adapted to live in preferred habitats and water quality conditions within these streams, and relatively rapid human-induced changes pose a unique challenge for their continued survival and persistence. This is especially true for our native freshwater mussels belonging to the family Unionidae, which are already among the most imperiled groups of fauna on the planet. One such factor associated with changing environmental conditions in a climate-influenced scenario that may adversely impact freshwater mussels inhabiting coastal rivers is sea level rise and accompanying changes in the salinity regime. For example, a recent published study has shown that 42% of coastal North Carolina could be inundated with 100 cm of sea level rise and that evaluating this risk is essential for understanding adaptation potential and decision making. Therefore, the overall aim of this project is to investigate the adaptation and vulnerability potential of a native freshwater mussel living in coastal riverine drainages to climate-induced, sea level rise, specifically fluctuating salinity, temperature, and flow regimes. The specific objectives of our study are to: (1) assess the vulnerability of the Tidewater Mucket (<i>Leptodea ochracea</i>), an imperiled freshwater mussel species that resides in lower Atlantic Slope coastal drainages to salinity by conducting standard sensitivity tests with early life stages (e.g., larvae, juveniles) of the mussel under controlled laboratory conditions; (2) determine the potential effects of natural riverine salinity gradients on adult mussels by conducting a reciprocal transplant experiment with salinity adapted and non-salinity adapted mussels; and (3) develop a risk-based scenario of mussel salinity tolerances in existing occupied habitats incorporating predictions in sea level rise and projected salinity ranges. This project directly addresses Southeast Climate Adaptation Science Center and partner agency priority topics and is a collaborative effort among North Carolina State University, the U.S. Geological Survey’s North Carolina Cooperative Fish and Wildlife Research Unit, the U.S. Fish and Wildlife Service’s Raleigh North Carolina Field Office, the North Carolina Wildlife Resources Commission, the Virginia Department of Game and Inland Fisheries, and the University of Georgia. The peer-reviewed publications, relevant infographics for web sites, and visualization maps of the overlap of sea level rise and mussel salinity sensitivity that will comprise our primary products and deliverables will illustrate the areas of rivers where mussels may be lost or conserved due to climate-induced salinity changes and will provide federal and state natural resource managers, policy makers, and future researchers with actionable management and conservation information and potential options for maintaining this highly imperiled, but valuable molluscan resource in the face of predicted climate-induced sea level rise and salinity fluctuations.
Association of Flow Regime with Fish and Invertebrate Assemblages in Caribbean Streams and Rivers	September 2020	The flow regime (i.e., the rate and timing of water flow) is a central physical factor regulating the dynamics of biotic communities in stream and river ecosystems. The determination of optimal flow regimes that meet societal demands for water resources while sustaining and enhancing aquatic life is especially applicable to tropical island aquatic ecosystems, and the Caribbean island of Puerto Rico is an ideal landscape upon which to empirically research such dynamics. Recent destructive tropical storms in the Caribbean further compel and facilitate study of extreme disturbance, both as flooding and drought, and the need to plan adaptation strategies is critical. In response to critical information and research needs, we propose research to address specific objectives, with an ultimate goal of understanding how stream flow dynamics affect aquatic communities, as an initial step toward ultimately developing environmental flow prescriptions to sustain and enhance aquatic life in Caribbean streams and rivers. The proposed research is multidisciplinary, including aspects of ecology, fishery science, hydrology, and climate science, and spans multiple spatial, temporal, and organizational scales. The objectives will be addressed via empirical data analyses of physical and biotic parameters on the island of Puerto Rico, but the findings may be applicable and informative to other tropical Caribbean islands and nations.

Applying downscaled climate projections to inform decisions	June 2019	This project is designed to help prevent listing Eleutherodactylus species that are at risk of becoming endangered under the Endangered Species List. Eleutherodactylus species are of conservation interest, and are typified by high endemism, relative low vagility, and largely stenoclimatic. This project will address two objectives that will help the decision makers in the U.S. Fish and Wildlife Service to formulate conservation measures. First, ascertain physiological thresholds (temperature, humidity) of selected species (biological models). This critical to permit forecasting species distribution in response to environmental changes and identify potential environmental refugia. Second, develop and test translocation protocols to either enhance populations via reintroductions or translocations to locations characterized by long-term suitability (refugia). Suitable areas for long-term conservation will be identified by combining physiological threshold information, downscaled climate projections (SE Climate Science Center), and a decision support tool to conduct habitat threats and risk assessments.

Advancing Use and Application of Diverse Data Sources and Species Distribution Models.	September 2018	We propose to develop an analytical framework that integrates multiple data sources to efficiently and effectively understand current and future avian distribution patterns and the potential for sustaining populations. Arriving at these inferences will be dictated, in large measure, on the availability and suitability of a variety of data sources to populate models. In recent years, non-traditional data gathering approaches (e.g., citizen science) have gained impetus and prominence due to their appeal and acceptance by the public. Cumulative data raises the prospect of its potential to supplement or complement other data sources (e.g., BBS, ARMI, NAAMP), and thus, improve inferences about species distribution and responses to a changing environment if used rigorously. The framework will also be useful to identify critical information gaps and provide guidelines to collect data in ways that reduce specified uncertainties in model inferences, and will be applicable to other taxa.

Optimal Sampling of Animal Communities.	September 2019	The US Fish and Wildlife Service (USFWS) has approximately 2.4-2.5 million acres of private lands enrolled in the Safe Harbor Program for Red-cockaded Woodpeckers (RCW) across the Southeast. The RCW could be viewed as a “surrogate” species, and the interest of the USFWS is in quantifying and evaluating the conservation benefits of RCW practices on non-surrogate species. The objective of this work is to develop a sampling scheme that will help USFWS quantify the benefits of Safe Harbor Management Agreements (SHMA) on non-surrogate species across southeastern United States. Because SHMAs influence present and future habitat conditions, the sampling scheme will be geared towards estimating parameters that quantify species richness and the dynamics of single species or avian communities over time (e.g., occupancy, extinction and colonization rates, inference about interactions). This work will tap existing occupancy-based models, develop extensions if needed, but center their application around a sound and flexible sampling design for implementation across the southeast.

NRCS Habitat Enhancement and Best Practices Program: opportunities to maximize the presence of pollinators and the positive impact of the program on natural resources and coffee growers.	December 2018	Land use patterns in Puerto Rico have caused severe forest fragmentation island wide, threatening species persistence through habitat isolation and declining habitat quality. Habitat protection is expensive, and may exclude alternatives that yield desirable conservation outcomes. Incorporating non-protected habitats (e.g., restored-shade coffee plantations) into strategy habitat conservation initiatives is a viable strategy to enhance species persistence and best management practices (e.g., pollinators) without affecting the economic bottom line of landowners. This project will inform decision makers of the USDA-Natural Resources Conservation Service (Caribbean) and U.S. Fish and Wildlife Service on where and when to invest shade-restoration efforts in the central mountainous region of the island. Alternatives will be ranked by costs and benefits in terms of landscape habitat connectivity and redundancy, and ultimately, species persistence. The project is being done in coordination with the USDA-Natural Resources Conservation Service (Caribbean) and the Caribbean Field Office of the U.S. Fish and Wildlife Service.

National Biogeographic Analysis & Synthesis	September 2019	The threats posed by climate change, urbanization, and invasive species, underscore the need for proactive management. However, conservation planning at regional and national extents continues to be limited by the lack of consistent, detailed and current data on biological resources. The goal of this proposal is to provide data, synthesis, and analyses to increase our understanding of the status of biodiversity and drivers of change. We will emphasize factors affecting national trust resources. To meet the project’s goal, we will: 1) analyze trends in biodiversity, investigating drivers of change and potential implications for future changes in diversity; 2) synthesize data and update species-habitat distribution maps to determine the current status of biodiversity in the nation; and 3) assist in building a National Biogeographic Map and a central tool for disseminating the synthesis of information.

Development of Long-term acoustic monitoring program and projected species distribution under future scenarios in the US Caribbean.	September 2021	Landuse patterns and projected global warming represent two major drivers that induce population declines and range contractions of many resident avian and amphibian species in Puerto Rico. This project will create species distribution maps for bird and anuran species that are critically endangered, vulnerable or data deficient and will use future climate scenarios to determine how their distribution may change in the future. Present protected areas will not suffice<b> </b>to safeguard species of great conservation need under climate change; therefore, decision makers should consider establishing larger protected areas, buffer zones, and connectivity between protected areas. This work provides State and Federal conservation agencies with a blueprint to frame habitat conservation strategies. The project is a collaboration with researchers from the University of Puerto Rico (Rio Piedras), Southeast Climate Adaptation Science Center, and biologists of the Science Applications and Caribbean Field Office of the U.S. Fish and Wildlife Service.

Characterizing Uncertainty in Changing Precipitation Regimes for Ecological and Hydrological Applicaitons in the Southeast and the Caribbean US.	August 2021	Changing precipitation regimes, such as changes to rainfall intensity or prolonged drought, threaten both the natural and built environment. Changes in local to regional precipitation regimes is a result of complex interactions within the climate system, and to better understand how these climate system processes change in a warmer climate requires special attention to regionally relevant atmospheric processes. Climate change simulations are typically at spatial scales (>100-km), and it is well known that climate models are unable to resolve important precipitation processes at these coarser resolutions, especially with respect to precipitation extremes. This research uses high-resolution regional climate models at relevant spatial scales to better characterize, quantify, and understand changing precipitation processes as the climate warms. The research uses a co-production framework where stakeholders inform the design of the high-resolution climate model experiments while creating data relevant to the needs of ecological and hydrological applications within the Southeast and Caribbean US. The current focus is to provide high-resolution climate model data and perform relevant analysis informed by scientists and stakeholders concerned with species conservation and hydrologic design. This project is a joint effort of researchers within USGS and the US EPA with additional stakeholders interested in project outcomes including the US Fish and Wildlife Services, USFS, Federal Highway Administration, and the NC Department of Transportation.

Impacts of Global Change on Biotic Resistance, Resilience, and Ecosystem Services in Caribbean Fish Assemblages, Fisheries, and Aquatic Ecosystems	August 2023	Extreme events not only affect people but can have detrimental impacts on natural resources, such as fish and freshwater habitat. Impacts of extreme events, like hurricanes, tornadoes, and extreme flooding, have immediate consequences, but also have the ability to alter habitat and animals far in the future by providing opportunities for exotic species to colonize new areas. Some fish communities in streams, rivers, and lakes may have the natural ability to resist the long-term impacts of extreme weather events. In this project, researchers will investigate the ability of Caribbean fish assemblages in Puerto Rico, which have both economic and cultural importance, to resist the impacts of extreme weather events. This information would allow natural resource managers on the island to develop appropriate responses to these events when managing fisheries resource. Furthermore, the project scientists will determine how changes in freshwater fish over time to hurricanes and other extreme weather events will impact the services (e.g., recreational and subsistence fishing practices) the fish will provide in the future. This work will not only deliver important information to fisheries managers and the community of Puerto Rico but could also be used by managers in other island systems.	Ecological disturbance and its impacts on organisms and ecosystems is a longstanding concept in ecology. Understanding and planning for the effects of disturbances, such as extreme weather events, on natural resources may help managers respond to the impacts of extreme events more effectively. The diversity of freshwater fish species in Puerto Rico may provide natural biotic resistance and resilience to colonization by nonnative species following disturbances; however this has not yet been studied in Caribbean island freshwater ecosystems. Puerto Rico provides an ideal study location to test this hypothesis in Caribbean fish assemblages and apply the results to other similar closed freshwater island systems. We propose to determine changes in stream and river fish assemblages over time at multiple temporal scales (e.g., seasonal, annual, decadal), examine fish assemblages and fisheries dynamics in relation to biotic resistance from exotic species invasions while relating changes to landscape (e.g., dams and reservoirs) and climate influences, project changes in fish assemblages and their ecosystem services in the future, and determine the impacts on the community and stakeholders. Through regular communication, written reports, peer-reviewed publications, and other tailored communication products, we will transfer our results to regional stakeholders to help guide strategic planning efforts. Climate change is predicted to increase the number of extreme events globally, and having a clearer understanding of the impacts of such events on natural resources will help managers develop efficient adaptation strategies and allocate resources appropriately. This work will be a collaboration among the North Carolina Cooperative Fish and Wildlife Research Unit, North Carolina State University, USGS National Climate Change and Wildlife Science Center, and the Puerto Rico Department of Natural and Environmental Resources
Fishery Population and Habitat Assessment in Puerto Rico Streams: Project F-50.8	October 2023	We are compiling and synthesizing the most relevant information on the freshwater and diadromous fishes of Puerto Rico and publishing it in a comprehensive book. Information on the life history, distribution, identification, biology, ecology, conservation, and management of Puerto Rico fishes is to be included. A primary source of this information is the research findings from research conducted by the NC Cooperative Fish and Wildlife Research Unit on fishery populations and habitats in streams and rivers. These research findings will be supplemented by previous research and investigations published in the primary literature, and various agency reports on the relevant species and habitats will also be included.

Population Status and Genetic Structure of the Carolina Madtom	July 2018	The Carolina madtom, Noturus furiosus, is a small catfish endemic to the Neuse and Tar river basins of North Carolina. The species spans a restricted range in these two basins, and the Neuse basin population appears to be declining. We will conduct research to define the extant distribution and populations of the Carolina madtom and further quantify sampling bias and efficiency toward understanding and modeling the species distribution and abundance. We will also estimate critical parameters of genetic isolation and diversity within and among populations. These findings will provide critical, timely information for the Species Status Assessment, inform protective listing decisions, and guide conservation planning for the species.	None

Applying mark-resight, count, and telemetry data to estimate effective sampling area and fish density with stationary underwater cameras. Canadian Journal of Fisheries and Aquatic Sciences. https://doi.org/10.1139/cjfas-2023-0373 \| Abstract	August 2024	Accurate estimates of abundance and density within geographically open populations must account for sampling gear effective sampling area (ESA). We describe a Marked N-Mixture model to estimate ESA and density (number of individuals/unit area) from repeated counts of unmarked and marked individuals, integrating mark-resight, camera counts, and telemetry data of red snapper (<i>Lutjanus campechanus</i>)<i> </i>at a 1.6 km<sup>2</sup> reef off North Carolina, USA. Cameras recorded observations of unmarked and marked individuals, whereas telemetry data indicated the number of tagged fish present on the reef. We estimated density (95 individuals/km<sup>2</sup>, 95%CI.:58–149), ESA (which was lower when current direction was towards the camera), detection probability (0.06, 95%CI.: 0.03–0.09), and covariate relationships. Simulation studies under different scenarios of data quality and space use identified positive bias in density estimates from N-mixture models due to fish movement, while the Marked N-Mixture model returned unbiased estimates of density and ESA. Our approach allowed the estimation of density, improved precision, and reduced the bias of parameter estimates, even under scenarios of poor data and animal movement, and can be applied to other geographically open populations where count and telemetry overlap in space and time.

Transactions of the American Fisheries Society 141:402-413. \| Abstract \| Publisher Website	March 2012	Anadromous fish populations within the Cape Fear River, North Carolina have declined substantially since the late 1800s. Three low-head lock and dam structures contributed to this decline by limiting access to upstream spawning habitat. We used egg sampling and sonic telemetry to examine the effects of the lock and dam structures on migration and spawning activity of American shad Alosa sapidissima and striped bass Morone saxatilis. Egg distribution and stage of development suggest that most American shad spawning took place downstream of the lowermost lock and dam (LD-1). The predicted mean density of stage-1 American shad eggs at a water temperature of 21 °C was 895 per 1,000 m3 (95% credible interval 800-994) below LD-1, 147 (103-197) below the second lock and dam (LD-2) and 32 (17-49) below the uppermost lock and dam (LD-3). The probability of capturing a stage-1 American shad egg was strongly dependent on water temperature and hour of egg collection. Transmitter detections for 20 sonic-tagged American shad and 20 striped bass in 2008 showed that the majority of both species moved upstream of Lock and Dam 1, with 35% of American shad and 25% of striped bass migrating upstream of LD-3. Based on passage rates at the three locks and dams, American shad would be expected to be most abundant downstream of LD-1 and upstream of LD-3. For striped bass, the section of the river between LD-2 and LD-3 had the highest egg collections and highest predicted proportion of the run. In combination, these results demonstrate that the locking program provides some access to historical spawning habitat, although further improvements in fish passage could benefit both species.

Marine Ornithology 41(Special Issue): 1-43. \| Abstract	July 2013	The Black-capped Petrel (Pterodroma hasitata) was believed extinct throughout much of the twentieth century. It is the only gadfly petrel currently known to breed in the Caribbean Basin. Now seriously endangered, the species has been extirpated from Martinique, Dominica, and Guadeloupe and breeding populations currently occur only on Hispaniola and perhaps Cuba A related form (now considered a full species) once bred, but is now apparently extinct, on Jamaica. The Black-capped Petrel breeding population may number as few as 500 breeding pairs. Remaining populations suffer from multiple threats to terrestrial and pelagic habitats, harvest by humans, and predation by introduced mammals. The exact sizes, locations, and detailed chronologies of all Black-capped Petrel breeding sites remain poorly-studied, although major colonies are today apparently restricted to steep sea and inland cliffs along the La Selle Ridge in Hispanolia. The largest known breeding population occurs in Haiti, although there is continued discussion about a possible breeding site in Cuba in the Sierra Maestra mountain range. Accounts from Cuba are based on the unverified assumption that birds observed at sea just offshore of that island are breeding locally. All evidence at present indicates that waters in or adjacent to the Florida Current and the Gulf Stream between north Florida and southern Virginia provide the primary foraging range of Black-capped Petrels. A small foraging area just off of SE Cuba has also been reported, but the extent and seasonal use of this area are unknown. Concentrations of birds can be found along the Gulf Stream in southeastern U.S. waters throughout the year, where the birds are particularly common in May, August, and late December through early January. Concentrations of adult birds during winter, when peak breeding activity is underway, suggest that breeding birds forage along the Gulf Stream while commuting to and from breeding colonies. Such long-distance foraging is certainly possible for species of the Genus Pterodroma. Potential threats to Black-capped Petrels include introduced predators, human encroachment on breeding and foraging habitats, and offshore oil, gas, and wind energy development. Increased mercury levels associated with petroleum production also pose a potential threat, as the Black-capped Petrel seems to be highly susceptible to mercury bioaccumulation compared to other pelagic species. In addition, fires and other bright light sources are known to attract Black-capped Petrels, making collisions with wires and other structures on lighted ships and platforms a potential concern. Haitian social-economic instability and increasing habitat loss suggest the likelihood of further population declines and increasing vulnerability of the species to extinction. Our findings are in accord with the recent decision by the USFWS to evaluate the need for additional protection of the species and the primary foraging habitat off of the SE United States under the Endangered Species Act (USFWS 2012). Additional conservation measures and research strategies that warrant further consideration include, (1) protection, monitoring, and management of known breeding populations and nesting habitat in the Dominican Republic and Haiti through predator control, the installation of artificial nest burrows in appropriate sites, and hiring local wardens at breeding sites during the nesting season, (2) local and regional training, education, and public awareness (e.g., Blanchard and Nettleship 1992), and (3) restoration of the original name ‘Diablotin’ for standard usage to promote the historical and cultural importance of this species, (4) studies to determine the distribution and genetic variability in the remaining populations and; (5) studies of satellite-tagged birds to assess their seasonal and geographic use of pelagic habitats.

Bee species richness through time in an urbanizing landscape of the southeastern USA. Global Change Biology.. \| Abstract	December 2023	Compared to non-urban environments, cities host ecological communities with altered taxonomic diversity and functional trait composition. However, we know much less about how these urban changes take shape over time. Using historical bee (Apoidea: Anthophila) museum specimens supplemented with online repositories and researcher collections, we investigated whether bee species richness tracked urban and human population growth over the past 118 years. We also determined which species were no longer collected, and whether those species shared certain traits. Additionally, we looked at collector behavior over time. We focused on Wake County, North Carolina, US where human population size has increased over 16 times along with the urban area within its largest city, Raleigh, which has increased over four times. We estimated bee species richness with occupancy models, and rarefaction and extrapolation curves to account for imperfect detection and sample coverage. To determine if bee traits correlated with when species were collected, we compiled information on native status, nesting habits, diet breadth, and sociality. We used non-metric multidimensional scaling to determine if collectors contributed different bee assemblages over time. In total, there were 328 species collected in Wake County. We found that while bee species richness varied there was no clear trend in bee species richness over time. However, recent collections (since 2003) were missing 195 species and there was a shift in trait composition over time, particularly an increase in above-ground nesters. The top collectors in the dataset differed in how often they collected bee species, but this was not consistent between historic and contemporary time periods as some contemporary collectors grouped closer than others together potentially due to focusing on urban habitats. Use of historic collections and complimentary analyses can fill knowledge gaps to help understand temporal patterns of species richness for taxonomic groups that may not have long-term data.

Canadian Journal of Fisheries and Aquatic Sciences 71:514-520. \| Abstract \| Download	December 2013	Discard mortality may contribute to the overall rate of fishing mortality for reef fishes with physoclistous bladders due to barotrauma. We estimated survival rates of discarded black sea bass in various release conditions using tag-recapture data. Fish were captured with traps and hook and line from a narrow depth range (29 - 34 m) off the coast of North Carolina, USA, marked with internal anchor tags, and observed for release condition. We also tagged fish on the bottom using SCUBA; these fish served as a control group for which we assumed survival was similar to fish that were never captured. Survival by release condition was estimated as the ratio of return rate of fish in each compromised condition relative to return rate of the control group. Discard survival for the hook and line and trap fisheries in this region was estimated by applying condition-specific survival rates to fish released in each condition during independent (non-tagging) recreational and commercial fishing operations. Relative to fish tagged on the bottom, the survival rate of surface-released fish in the best condition was 0.94 (95% credible interval 0.72 – 1.32). Adjusted for results from the underwater tagging experiment, fish with evidence of external barotrauma had a median survival rate of 0.98 (0.73 – 1.41); fish with hook trauma had a median survival rate of 0.39 (0.18 – 0.74); and floating/presumably dead fish had a median survival rate of 0.18 (0.09 – 0.33). Applying these condition-specific estimates of survival to non-tagging fishery data, we estimated a discard survival rate of 0.88 (0.66 – 1.25) for 11 hook and line data sets from waters 20 to 35 m deep and 0.93 (0.71 – 1.31) for 10 trap data sets from 11 to 29 m deep. The tag-return approach using a control group with no fishery-associated trauma represents a powerful method to accurately estimate absolute discard survival of physoclistous reef species.

Field Ornithology 84:355-366/ \| Abstract	December 2013	Abstract.- A greater understanding of King Rail (Rallus elegans) reproductive ecology in fire-managed marshes has been identified as a means to help alleviate their declining trend in freshwater emergent marshes. Call-broadcast surveys, nest searches and nest surveillance were used to estimate the probability of detecting reproductive activity and nest success at Mackay Island and Back Bay National Wildlife Refuges, North Carolina and Virginia, in 2009 and 2010. The probabilities that a surveyed plot was occupied ( ) and contained an active nest ( ) were higher in recently burned (0-1 years since burn [YSB]) marsh plots than in plots with 2 YSB in both refuges. Highest probabilities were recorded in 0-1 YSB plots at Mackay Island NWR ( = 0.96 0.04, = 0.75 0.18), and the lowest, in 2 YSB plots at Back Bay NWR ( = 0.21 0.10, = 0.03 0.04). Period nest survival from egg laying to hatching (31 days) was 0.48 (95% CI = 0.06 - 0.83), with an estimated 0.84 (95% CI = 0.60 – 1.0) for the incubation stage (21 days). While the linkage between occupancy and reproductive activity in 0-1 YSB marsh plots was established, low sample sizes precluded linking fire management and nest survival. Findings suggested that fire management creates habitat that holds potential for population growth. Studies focusing on the implications of prescribed burns for fitness should be conducted across multiple sites to capture variation in King Rail responses across its geographic range.

Linking demographic rates to local environmental conditions in support of Climate Adaptation Strategies for Eleutherodactylus frogs. Global Ecology and Conservation 28 (2021) e01624. \| Abstract	May 2021	Conducting managed species translocations and establishing climate change refugia are adaptation strategies to cope with projected consequences of global warming, but successful implementation requires on-the-ground validation of demographic responses to transient climate conditions. Here we estimated the effect of nine abiotic and biotic factors on local occupancy and an index of abundance (few or chorus) for four amphibian species (<i>Eleutherodactylus wightmanae</i>, <i>E. brittoni</i>, <i>E. antillensis,</i> and <i>E. coqui</i>) in Puerto Rico, USA. We also assessed how the same factors influenced reproductive activity of <i>E. coqui</i> and how species responded to hurricane María (20 September 2017). As predicted, occupancy and abundance of <i>E. wightmanae</i>, <i>E. brittoni</i> and <i>E. coqui</i> were positively and strongly influenced by abiotic covariates (e.g., relative humidity) that characterize high elevation, mesic habitats. <i>E. antillensis</i> exhibited the opposite pattern, with highest probabilities (≥0.6) recorded at ≤300 m and with average relative humidity <75%. Biotic covariates (e.g., canopy cover) had a weak influence on both parameters, regardless of species. High probabilities (≥0.9) of detecting an <i>E. coqui</i> chorus and active nests occurred at sites experiencing average relative humidity of >80% and temperature of ≤26° C. Moderate to high probabilities of detecting a chorus (0.4 - 0.7) were recorded at sites with average temperatures >26°C, but no reproductive activity was detected, implying that monitoring abundance alone could misrepresent the capacity of a local population to sustain itself. The possibility underscores the importance of understanding the interplay between local demographic and environmental parameters in the advent of global warming to help guide monitoring and management decisions, especially for high elevation specialists. Hurricanes can inflict marked reductions in population numbers, but impacts vary by location and species. We found that the abundance (chorus) of <i>E. antillensis</i> and <i>E. brittoni</i> increased after the hurricane, but the abundance of the other two species did not differ between years. Lack of impacts was probably mediated by low structural damage to forest tracts (e.g., 9% canopy loss). Our findings help assess habitat suitability in terms of parameters that foster local population growth, which provides a basis for testing spatio-temporal predictions about demographic rates in potential climate refugia and for designing criteria to help guide managed translocations.

Caribbean Journal of Science. \| Abstract	January 2022	A concern about statistics in wildlife studies, particularly of endangered and threatened species, is whether the data collected meet the assumptions necessary for the use of parametric statistics. This study identified published papers on the nine endangered and six threatened species found only on Puerto Rico using 5 different databases. The results from the database Zoological Record identified the most articles, including all identified by the other databases. Of the 220 articles identified, 113 included some form of statistics, 28 used only descriptive statistics, 42 included parametric statistics, 24 used only nonparametric statistics, and 19 reported both parametric and nonparametric statistical analyses. This meta-study showed that the percentage of articles with no statistical treatment decreased in the most recent 20 years and that although parametric statistics continue to be most commonly used in published wildlife studies of Puerto Rican wildlife, there has been a distinct increase in the use of nonparametric statistics over time.

Transactions of the American Fisheries Society 143:673-688. \| Abstract \| Download	April 2014	Despite extensive management and research, American shad Alosa sapidissima populations have experienced prolonged population declines, and uncertainty about underlying mechanisms remains. In the springs of 2007 through 2010, we used a resistance board weir and passive integrated transponder (PIT) technology to capture, tag, and track American shad in the Little River, North Carolina, a tributary to the Neuse River with complete and partial low-head dam removals. Our objectives were to examine potential demographic differences in timing and habitat use and to estimate season weight loss, survival, and abundance. Males typically immigrated earlier than females, but otherwise exhibited relatively similar migratory patterns. Weight loss displayed a positive relationship with cumulative temperature during residence. Emigrating males lost 30% or less of their initial weight compared to 50% or less for females, indicating potential survival thresholds. Spawning season survival was low as estimates ranged from 0.07 to 0.17; no distinct factors (e.g., sex, size, migrations) contributing to survival were documented. Sampled and estimated American shad abundance increased from 2007 through 2009, but was lower in 2010. This new American shad spawning information may further aid restoration efforts.

Agriculture, Ecosystems and Environment 307 (2021) 107196. \| Abstract	January 2021	As agriculture expands to meet the needs of a growing global population, natural ecosystems are threatened by deforestation and habitat fragmentation. Tropical agroforestry systems offer a sustainable alternative to traditional agriculture by providing food for production while also supporting biodiversity and ecosystem services. Previous studies have shown that these systems may even improve crop pollination, but the mechanisms of how these improvements occur are still poorly understood. Using coffee as a focal crop, we explored how microclimatic conditions affected nectar traits (sugar and caffeine concentration) important for pollinator visitation. We also studied how microclimate, floral traits, floral availability at the coffee plant level, availability of floral resources provided by other plant species in the agroecosystem (“neighborhood floral availability”), and the presence of other bees affected the amount of time bees spent foraging on coffee flowers and the proportion of coffee pollen carried on their bodies. We explored these factors using the two dominant coffee species farmed on Puerto Rico, <i>Coffea canephora</i> and <i>C. arabica</i>, under sun and shade management.<i> </i>We found that high nectar sugar concentration and temperature were important predictors of short floral visits (<15 seconds), while increased numbers of bees and open coffee flowers were important predictors of longer floral visits (16-180 seconds). High nectar caffeine concentration was an important predictor of longer visits on <i>C. arabica </i>flowers while the opposite was observed for <i>C. canephora </i>flowers. For both species, high coffee floral availability was the main predicting factor for the proportion of coffee pollen on the bees’ bodies. Surprisingly, neither neighborhood floral availability nor the type of coffee plantation (agroforest/shade or sun) were important predictors of bee visitation. These results suggest non-coffee flowering plants in coffee plantations were neither competitors nor facilitators of coffee plants for pollinators. Additionally, most of the bees surveyed were carrying ≥80% pollen from one species (<i>C. arabica </i>or <i>C. canephora</i>), likely resulting in little heterospecific pollen deposition between <i>Coffea</i> and non-<i>Coffea</i> flowers. Shade trees in coffee plantations do not detract from pollinator visitation to coffee flowers, suggesting that the provision of multiple ecological and wildlife conservation benefits by shade trees is not in conflict with a grower’s ability to maximize the benefits of insect pollination on fruit production.

PLoS ONE 8(8): e71552. doi:10.1371/journal.pone.0071552. \| Abstract \| Download	August 2013	Worldwide, sturgeons (Acipenseridae) are among the most endangered fishes due to habitat degradation, overfishing, and inherent life history characteristics (long life span, late maturation, and infrequent spawning). As most sturgeons are anadromous, a considerable portion of their life history occurs in estuarine and marine environments where they may encounter unique threats (e.g., interception in non-target fisheries). Of the 16 marine-oriented species, 12 are designated as Critically Endangered by the IUCN, and these include species commercially harvested. We review important research tools and techniques (tagging, electronic tagging, genetics, microchemistry, observatory), and discuss the comparative utility of these techniques to investigate movements, migrations, and life-history characteristics of sturgeons. Examples are provided regarding what the applications have revealed regarding movement and migration, and how this information can be used for conservation and management. Through studies that include Gulf (Acipenser oxyrinchus desotoi) and Green Sturgeon (A. medirostris), we illustrate what is known about well-studied species and then explore lesser-studied species. A more complete picture of migration is available for North American sturgeon species, while European and Asian species, which are among the most endangered sturgeons, are less understood. We put forth recommendations that encourage the support of stewardship initiatives to build awareness and provide key information for population assessment and monitoring.

ISSN 2326-7119. \| Abstract	July 2020	Biodiversity metrics are frequently used to guide conservation planning because they can summarize biogeographical attributes of plant and animal communities quickly and at multiple scales. Attributes include habitat features of high conservation value, representativeness and redundancy of biological communities. We conducted a rapid ecological assessment of resident avian species in the west-central mountainous region of Puerto Rico in 2015, a landscape dominated by coffee cultivation. We focused on this landscape because shade and shade-restored coffee plantations offer an opportunity to complement protected habitat (e.g., reserves) to enhance species persistence. We used species richness, which tallies the number of unique species, and a quadratic entropy index of diversity, which incorporates interspecific taxonomic differentiation to evaluate species representativeness and redundancy across sun and shade coffee plantations and secondary forest. We surveyed 120 sites, calculating both metrics using species-specific occupancy probabilities estimated from community-level occupancy models. Species representativeness and redundancy was high as neither metric was able to discriminate among habitat classes, possibly because plant communities were redundant and the avian community was dominated by species adept at exploiting altered habitats. Similarly, we could not discriminate among avian communities modeling each biodiversity metric as a function of site-specific habitat covariates. Our findings and available knowledge on avian community demographics suggest that conservation strategies could couple protected habitat (e.g., reserves) and restored habitat (e.g., coffee plantations) to enhance species diversity and persistence across human-modified landscapes.

Coffee plantations, hurricanes and avian resiliency: insights from occupancy, and local colonization and extinction rates in Puerto Rico. Global Ecology and Conservation 27 (2021) e01579 \| Abstract	April 2021	Insights on impacts and resiliency of avian species with respect to hurricanes in the Caribbean have largely focused on responses measured in protected habitats. We assessed avian responses in non-protected habitat, specifically shade-restored coffee plantations, because their structural complexity retains many attributes of secondary forests, and may contribute to landscape scale species resiliency. We tallied species richness and estimated occupancy probability of 12 resident avian species, after adjusting for imperfect detection, to assess the impact of hurricane Maria (20 September 2017) in shade-restored coffee plantations. For five of those species, we also estimated local colonization and extinction probabilities to assess their prospect of rebounding (resiliency) in the context of two stages of shade restoration. We used survey data collected March-June 2015-2017 (pre-hurricane) and 2018 (post-hurricane) in 58 coffee farms and satellite imagery to assess vegetation structure. Restored farms were grouped into two categories based on time-since-restoration: newly-restored and fully-restored. We predicted that mean percent forest cover in fully-restored farms (~30-40%) would revert to levels in newly-restored farms (<15%), with concomitant changes in occupancy by avian species. As predicted, mean percent forest cover (16.17 ± 4.27%) in fully-restored farms post-hurricane reverted to pre-hurricane levels in newly-restored farms (15.00 ± 5.61%). The loss represented 30-38% relative to the pre-hurricane cover levels. Detections of focal species dropped an average of 41% post-hurricane, with associated reductions in occupancy for 9/11 species. Occupancy of the Puerto Rican Bullfinch and Puerto Rican Spindalis reverted to levels detected in newly-restored plantations prior to the hurricane as predicted. Prospects of rebounding were more likely for species with invariant or increases in colonization probability (e.g., Yellow-faced Grassquit, Northern Mockingbird, Puerto Rican Spindalis). Rebounding for frugivores like the Puerto Rican Bullfinch would be protracted given that colonization rates dropped from 0.56 ± 0.12 (pre-hurricane) to 0.04 ± 0.2 (post-hurricane), regardless of restoration stage. Our work showed that the avian community associated with restored coffee farms exhibited a high degree of ecological resistance as the similarity in species composition before and after the hurricane was 81%, and all 12 focal species continued to occupy farms under both restoration stages. The prospect of the focal species to rebound (resiliency) was species-specific, and in some cases, mediated by their affinity to a particular farm restoration stage. The strength of hurricanes is projected to intensify with global warming. Pockets of undamaged or partially damaged shade-grown or fully-restored coffee plantations may contribute to species resiliency by increasing landscape level habitat redundancy, and facilitate habitat shifts to secure food resources or harbor source populations to colonize recovering, hurricane-damaged habitat tracts.

American Fisheries Society, Symposium 80, Bethesda, Maryland. \| Abstract \| Download	April 2013	Striped bass Morone saxatilis in inland reservoirs play an important role ecologically and in supporting recreational fishing. To manage these populations, biologists need information about abundance and mortality. Abundance estimates can be used to assess the effectiveness of stocking programs that maintain most reservoir striped bass populations. Mortality estimates can indicate the relative impact of fishing versus natural mortality, and the need for harvest regulation. The purpose of this article is to evaluate tagging studies as a way of obtaining information about abundance and mortality. These approaches can be grouped into three broad categories: tag-recapture, tag-return, and telemetry. Tag-recapture methods are typically used to estimate population size and other demographic parameters, but are often difficult to apply in large systems. A fishing tournament can be an effective way of generating tagging or recapture effort in large systems, compared to using research sampling only. Tag-return methods that rely on angler harvest and catch-and-release can be used to estimate fishing (F) and natural (M) mortality rates and are a practical approach in large reservoirs. The key to success in tag-return studies is to build in auxiliary studies to estimate short-term tagging mortality, short- and long-term tag loss, reporting rate, and mortality associated with catch-and-release. F and M can also be estimated using telemetry tags. Advantages of this approach are that angler non-reporting does not bias estimates and fish with transmitters provide useful ecological data. Cost can be a disadvantage of telemetry studies; thus combining telemetry tags with conventional tag-returns in an integrated analysis is often the optimal approach. In summary, tagging methods can be a powerful tool for assessing the effectiveness of inland striped bass stocking programs and the relative impact of fishing versus natural mortality.

We examined images obtained using a DIDSON multibeam sonar for Atlantic sturgeon Acipenser oxyrinchus, striped bass Morone saxatilis, white perch M. americana, and channel catfish Ictalurus punctatus of known size (20 – 141 cm) to determine the reliability of length estimates. For ranges up to 11 m, percent measurement error (sonar estimate – total length)/total length X 100 varied by species but was not related to the fish’s range or aspect angle (orientation relative to the sonar beam). Least-square mean percent error was significantly different from 0.0 for Atlantic sturgeon (x ̅ =-8.34, SE=2.39) and white perch (x ̅ =14.48, SE=3.99) but not striped bass (x ̅= 3.71, SE=2.58) or channel catfish (x ̅=3.97, SE=5.16). Underestimating lengths of Atlantic sturgeon may be due to difficulty in detecting the snout or the longer dorsal lobe of the heterocercal tail. White perch was the smallest species tested and it had the largest percent measurement errors (both positive and negative) and the lowest percentage of images classified as good or acceptable. Automated length estimates using Echoview software varied with position in the view-field. Estimates tended to be low at more extreme azimuthal angles (fish’s angle off-axis within the view-field) but mean and maximum estimates were highly correlated with total length. Software estimates were also biased by fish images partially outside the view-field and when acoustic crosstalk occurred (when a fish perpendicular to the sonar and at relatively close range is detected in the side lobes of adjacent beams). These sources of bias are apparent when files are processed manually and can be filtered out when producing automated software estimates. Multibeam sonar estimates of fish size should be useful for research and management if these potential sources of bias and imprecision are addressed.

Rice editors. Biology and management of inland striped bass and striped bass hybrids. American Fisheries Society, Symposium 80, Bethesda, Maryland. \| Abstract \| Download	April 2013	Hydroacoustic surveys have proven valuable for estimating reservoir forage fish abundance but are more challenging for adult predators such as striped bass Morone saxatilis. Difficulties in assessing striped bass in reservoirs include their low density and the inability to distinguish species with hydroacoustic data alone. Despite these difficulties, mobile hydroacoustic surveys have potential to provide useful data for management because of the large sample volume compared to traditional methods such as gill netting and the ability to target specific areas where striped bass are aggregated. Hydroacoustic estimates of reservoir striped bass have been made using mobile surveys, with data analysis using a threshold for target strength in order to focus on striped bass-sized targets, and auxiliary sampling with nets to obtain species composition. We provide recommendations regarding survey design, based in part on simulations that provide insight on the level of effort that would be required to achieve reasonable estimates of abundance. Future surveys may be able to incorporate telemetry or other sonar techniques such as side-scan or multibeam in order to focus survey efforts on productive habitats (within lake and vertically). However, species apportionment will likely remain the main source of error, and we see no hydroacoustic system on the horizon that will identify fish by species at the spatial and temporal scale required for most reservoir surveys. In situations where species composition can be reliably assessed using traditional gears, abundance estimates from hydroacoustic methods should be useful to fishery managers interested in developing harvest regulations, assessing survival of stocked juveniles, identifying seasonal aggregations, and examining predator–prey balance.

These models, which were based on a combination of published information and expert opinion, are often used to make decisions about hydropower dam operations and fish passage. The purpose of this study was to develop updated habitat suitability index models for spawning American shad in the southeastern United States, building on the many field and laboratory studies completed since 1985. We surveyed biologists who had knowledge about American shad spawning grounds, assembled a panel of experts to discuss important habitat variables, and used raw data from published and unpublished studies to develop new habitat suitability curves. The updated curves are based on resource selection functions, which can model habitat selectivity based on use and availability of particular habitats. Using field data collected in eight rivers from Virginia to Florida (Mattaponi, Pamunkey, Roanoke, Tar, Neuse, Cape Fear, Pee Dee, St. Johns), we obtained new curves for temperature, current velocity, and depth that were generally similar to the original models. Our new suitability function for substrate was also similar to the original pattern, except that sand (optimal in the original model) has a very low estimated suitability. The Bayesian approach that we used to develop habitat suitability curves provides an objective framework for updating the model as new studies are completed and for testing the model's applicability in other parts of the species' range.

Conservation Science and Practice 2020;e172.; DOI: 10.1111/csp2.172 \| Abstract	January 2020	Sustainable, conservation-oriented agricultural practices like shade coffee and agroforestry can enhance conservation objectives in tropical landscapes. Adoption of these practices, however, is influenced by numerous factors. We conducted a survey of 89 coffee farmers in Puerto Rico to understand their farming practices, experience with existing incentives, and willingness to participate in conservation programs. Quantitative analysis showed that current farming practices, farm size, and annual income from farming were associated with willingness to participate in conservation programs. Qualitative results suggested that financial considerations, conflicting state and federal incentives, lack of information about conservation programs, distrust in government, and land use restrictions might hinder participation. Some farmers perceived that sun farming – a practice incompatible with sustainable conservation - was required to be eligible for state agricultural incentives. The way some farmers practiced shade farming differed from the way suggested for conservation purposes, particularly in the type of shade trees and their cover density. Farmers highlighted the need for financial incentives to encourage adoption of shade farming. They also expressed concerns that participation in conservation programs could limit their land management autonomy. We suggest that availability of financial incentives, reconciliation of institutional barriers, increased outreach, and involvement of farmers in design of conservation programs can increase adoption and retention of conservation practices.

One example with growing importance for fisheries research is hydroacoustic technologies such as side-scan sonar. Advantages of side-scan sonar over traditional techniques include the ability to sample large areas efficiently and the potential to survey fish without physical handling—important for species of conservation concern, such as endangered sturgeons. Our objectives were to design an efficient survey methodology for sampling Atlantic Sturgeon Acipenser oxyrinchus by using side-scan sonar and to developmethods for analyzing these data. In North Carolina and South Carolina, we surveyed six rivers thought to contain varying abundances of sturgeon by using a combination of side-scan sonar, telemetry, and video cameras (i.e., to sample jumping sturgeon). Lower reaches of each river near the saltwater–freshwater interface were surveyed on three occasions (generally successive days), and we used occupancy modeling to analyze these data.We were able to detect sturgeon in five of six rivers by using these methods. Side-scan sonar was effective in detecting sturgeon, with estimated gear-specific detection probabilities ranging from 0.2 to 0.5 and river-specific occupancy estimates (per 2-km river segment) ranging from 0.0 to 0.8. Future extensions of this occupancy modeling framework will involve the use of side-scan sonar data to assess sturgeon habitat and abundance in different river systems.

Adaptation Strategies for Conserving Puerto Rico’s Sensitive Herpetofauna: a demonstrative case study using the plains coqui (coqui llanero, E. juanariveroi). Frontiers in Conservation Science, section Animal Conservation. \| Abstract	October 2024	The challenges of selecting strategies to adapt to climate change and other anthropogenic impacts is further complicated by the presence of irreducible uncertainties regarding future conditions. Decisions on long-term investments in land protection to achieve conservation objectives contain significant risk of failure due to these uncertainties. To address this challenge, decision makers need an arsenal of sophisticated but practical tools to help guide spatial conservation strategies. Theory asserts that managing investment risks can be achieved by diversifying an investment portfolio to include assets that are neutral or negatively correlated under a given set of conditions. We demonstrate an approach for formalizing the diversification of conservation assets (land parcels) by using their correlation structure to quantify the degree of risk for any proposed reserve design. We then apply this metric to identify optimal spatial investment portfolios by appropriately balancing risk with the expected conservation benefit. We illustrate a framework for identifying potential future habitat refugia to manage an endangered amphibian by integrating species distribution modeling, scenarios of climate change and sea level rise, and impacts to critical habitat. Using the plains coqui (“coqui llanero”), known from only three small wetland populations on Puerto Rico’s coastal plains, we evaluate the distribution of refugia for eight future scenarios and apply portfolio theory to help guide investment strategies to mitigate climate risks and increase the persistence of this species in the face of an uncertain future. Modeling projects substantial loss of Puerto Rican wetlands and reductions in species distribution, but conditional on the future scenario and with losses not equally distributed across the northern coast. Currently protected areas in the north, while offering limited protection of current llanero distribution, may contribute considerable value to future refugia. Optimizing a protected-area design with the objective of managing risk provides insights on possible benefits and limitations relative to an alternate strategy focused on maximization of cumulative conservation benefits. Some apparent limitations in outcomes of the risk-benefit optimization may be due to the availability of only a small percentage of negatively correlated parcels with which to reduce risk.

Using resiliency, redundancy, and representation in a Bayesian belief network to assess imperilment of riverine fishes. Ecosphere. http://dx.doi.org/10.1002/ecs2.4738 \| Abstract \| Download \| Publisher Website	January 2024	Conservation-prioritization frameworks are used worldwide to identify species at greatest risk of extinction and to allocate limited resources across regions, species, and populations. Conservation prioritization can be impeded by ecological knowledge gaps and data deficiency, especially in freshwater species inhabiting highly complex aquatic ecosystems. Therefore, we developed a flexible approach that calculates a species’ imperilment risk based on the conservation principles of resiliency, redundancy, and representation (i.e., the “three R’s”). Our approach organizes data on species traits, distributions, population connectivity, and threats within a Bayesian belief network capable of predicting resiliency and redundancy within representative ecological settings. Empirical data and expert judgement inform the model to provide robust and repeatable risk assessments for rare and data-deficient species. The model calculates resiliency at hierarchical spatial scales from distributional trends and population strength. Redundancy is estimated from numbers and connectivity among extant populations. Resiliency, redundancy, and species’ inherent vulnerability based on species traits collectively estimate extirpation risk within each unique ecological setting. Extirpation risks across ecological settings characterize representation and are aggregated to estimate global imperilment risk. We demonstrate the model’s utility with Piebald Madtom (<i>Noturus gladiator</i>), a species petitioned for listing under the U.S. Endangered Species Act. Our results revealed that resiliency, redundancy, and extirpation risks can vary spatially across the species’ range while identifying populations where additional sampling could disproportionally reduce uncertainty in estimated global imperilment risk. Our approach could standardize and expedite conservation status assessments, identify opportunities for early management intervention of at-risk species and populations, and strategically reduce uncertainty by focusing monitoring and research on priority information gaps.

Strategic Habitat Conservation and Adaptive Strategies for Recovery and Pre-listing Conservation of Eleutherodactylus (coqui) Amphibians in Puerto Rico. Cooperator Report (ScienceBase). \| Abstract	January 2024	We synthesized ecological data to inform decision makers on when climate-vulnerable amphibians should be translocated and where climate-resilient habitat should be protected. In objective 1, we showed critical thermal limits (CT<sub>Max</sub>)estimates conformed to the known distribution of focal species. Climate projections suggested that focal species will not be exposed to reported CT<sub>Max</sub> until at least 2060. Instead, species will be affected through long-exposure to elevated sub-lethal temperatures (≥25°C ≤36°C). Experimental releases indicated that there is no difference in initial, post-release daily survival rates between control and translocated individuals (DSR = 0.999 ± 0.001), and are not an added source of mortality, thus, it is a useful adaptation tool. In objective 2, genetic analyses for the endangered <i>Eleutherodactylus juanariveroi </i>suggested that the two known populations harbor unique genetic diversity, and were likely exchanging migrants in the past, but have more recently become isolated from one another. Other range-restricted <i>Eleutherodactylus</i> species exhibited extensive genetic structure in a principal components analysis of genetic variation, suggesting that they may require a finer scale of population management in recognition of genetic variability and to ensure resilience to future global change. In objective 3, we evaluated current habitat conditions and forecasted habitat change under future climates using <i>E. juanariveroi</i> as an illustrative example to demonstrate a framework for developing conservation strategies for climate sensitive-species. Temperature-mediated evapotranspiration, declining freshwater input, and sea level rise will promote saltwater intrusion and the transition of fresh marsh habitats in Puerto Rico. Conditional on scenarios of future biotic and abiotic conditions, uncertainty, and decision-maker risk attitudes, we developed a spatial reserve-design planning tool to optimize species persistence and manage risk<i>. </i>The multi-disciplinary project we described represents a sound approach to draw appropriate inferences about organismal and habitat vulnerability to non-stationary climate conditions, help identify alternative actions to deal with potential impacts, and assist decision makers in the formulation of long-term strategies for species conservation by considering climate-induced uncertainty and risk.

Cooperator Report for the Southeast Climate Science Center. \| Abstract	February 2021	The U.S. Fish and Wildlife Service and the Puerto Rico Department of Natural and Environmental Resources want to develop a plan of actions to protect 12 species of coqui frogs (<i>Eleutherodactylus</i> spp.) that are currently considered at risk of being considered threatened or endangered, requiring additional protections under the Endangered Species Act. Actions center on two possible adaptation strategies: a) translocations to suitable, unoccupied habitat, and b) identifying climate-resilient habitats to ensure the persistence of species. Knowledge required to implement these strategies includes understanding how microhabitat and microclimatic factors – the local environmental conditions around individual frogs influence their occupancy (distribution), abundance, and reproduction; these were estimated by focusing on four representative species (<i>E. wightmanae</i>, <i>E. brittoni</i>, <i>E. antillensis,</i> and <i>E. coqui</i>). The abundance of all species but <i>E. antillensis</i> was positively and strongly influenced by moisture levels. As expected, <i>E. antillensis</i> exhibited an opposite relationship. Similarly, the reproductive activity of <i>E. coqui</i> was influenced by higher relative humidity and the presence of a chorus of other individuals. We found that our four focal species were not affected (e.g., abundance, reproduction) by the passing of hurricane Maria in September 2017, possibly because fallen debris creates conditions of increased food and shelter. Our findings help to assess habitat suitability, potential climate refuges, and inform timing for<i> </i>managed translocations.

Management of Biological Invasions 15:505–518. \| Abstract	December 2024	Oxbow lakes are highly productive waterbodies that host multiple life stages of many freshwater aquatic species. These lakes also provide foraging and rearing habitat to the invasive silver carp (<i>Hypophthalmichthys molitrix</i>) enabling populations to grow in biomass and abundance that can add propagule pressure to connected waterways and oxbows within the Mississippi River Basin. Ecologically these fish are undesirable because they overlap in diet and may compete for resources with native fishes and negatively impact recreational fisheries. Our goal was to evaluate silver carp distribution patterns in a major Mississippi River oxbow lake to inform removal programs and precision harvesting. We implanted 35 adult silver carp with acoustic tags and released them into the lake. Periodic tracking over 365 d revealed that fish were predominantly found in lake areas with water depths ranging from 2.0 to 5.9 m during all seasons, despite the availability of shallower and deeper water. Silver carp tended to aggregate in the wintertime (December-February) relative to other seasons. This information about lake area uses and seasonal aggregations could inform removal efforts in invaded waterbodies by exploiting natural behavioral and temporal vulnerabilities of this highly invasive and difficult-to-capture fish.

Ecological Applications 31: e02410. \| Abstract	October 2021	Estimates of species abundance are critical to understand population processes and to assess and plan management actions. However, capturing and marking individuals for abundance estimation can be economically and logistically prohibitive, particularly for cryptic species. Camera traps can collect data at temporal and spatial scales necessary for estimating abundance, but the use of camera traps comes with limitations when target species are not uniquely identifiable (i.e., “unmarked”). Abundance estimation is particularly useful in the management of invasive species, and herpetofauna are being recognized as some of the most pervasive and detrimental invasive species. However, the use of camera traps for these taxa comes with additional challenges with relevancy across multiple taxa. It is often necessary to use lures to attract animals in order to obtain sufficient observations, yet lure-attraction can influence species’ landscape use and potentially induce bias in abundance estimators. We investigated these challenges and assessed the feasibility of obtaining reliable abundance estimates using camera trapping data on a population of invasive brown treesnakes (<i>Boiga irregularis</i>) in Guam. Data were collected using camera traps in an enclosed area where snakes were subject to high-intensity capture-recapture effort, resulting in presumed abundance of 116 snakes (density = 23/ha). We then applied Unmarked Spatial Capture-Recapture (USCR), Random Encounter and Staying Time, Space to Event, and Instantaneous Sampling estimators to photo-capture data to estimate abundance and compared estimates to our presumed abundance. We found that all estimators for unmarked populations performed poorly, with inaccurate or imprecise abundance estimates that limit their usefulness for management. We further investigated the sensitivity of these estimators to increasing lure attraction (i.e., violating the assumption that animal behavior is unchanged by sampling) and camera density. Increasing lure attraction and camera density both resulted in higher abundance estimates, with the USCR estimator particularly sensitive to changing camera density while other estimators were more sensitive to increasing lure attraction. Each estimator rarely recovered truth or suffered from convergence issues. Our results indicate that, when limited to unmarked estimators and the use of lures, camera traps alone are unlikely to produce abundance estimates with utility to managers.

Connectivity patterns between floodplain lakes and neighboring streams in the historical floodplain of the Lower Mississippi River. Ecological Indicators 169. https://doi.org/10.1016/j.ecolind.2024.112808 \| Abstract	November 2024	Hydrologic connectivity, the intricate network of water pathways linking diverse aquatic habitats, plays a pivotal role in facilitating the exchange of aquatic species and materials between the main river channels and adjacent waterbodies. This study quantified hydrologic connectivity for 1,283 floodplain lakes within the historical floodplain of the Lower Mississippi River using metrics derived from satellite imagery, stream gauge, and geospatial information. Our goal was to assess patterns of connection frequency between lakes and streams in this floodplain. We estimated eight metrics descriptive of the temporal aspects of hydrologic connectivity and identified trends in the connectivity characteristics of lakes by lake features and by the sizes of adjacent linked streams. We found that each lake maintained a signature recurring pattern of connection, with specific months of connectivity followed by periods of disconnection, which is likely tied to the interaction between lake characteristics and precipitation seasonality. Larger lakes typically exhibited increased hydrologic connectivity compared to their smaller counterparts. This effect is likely due to the larger surface area and volumetric capacity that large lakes inherently have, which facilitates interaction with adjacent waterbodies. Conversely, smaller lakes may experience limited or no hydrologic connectivity, particularly if they are geographically isolated. Additionally, because of smaller volumes, smaller lakes are more vulnerable to losing storage during dry periods, which can result in temporary or long-term isolation from neighboring rivers. Regardless of size, lakes connected to large streams exhibited more prolonged, recurring, and seasonally indistinct connections, as well as a higher degree of continuity in their hydrologic interactions. There was often reduced connectivity in lakes surrounded by increased agriculture. However, these generalizations are subject to many exceptions since local factors and human-induced changes such as levees, artificial channel, and weirs may override the general trends. The insight gained from this hydrologic connectivity analysis offers the possibility to augment floodplain management actions, for example, by allowing the building of strategic frameworks for restoring connectivity and ecologic integrity, or to inform the control of invasive species spread that typically plagues agricultural floodplains.

Poster presentation.	August 2016	Our objective was to determine the diel-scale recruitment phenology of postlarval Sirajo Gobies in the Río Grande de Arecibo, Puerto Rico. We observed that peaks in postlarval ingress occurred from midnight to 0600 with maximum mean ingress between the hours of midnight and 0300. These results indicate that Sirajo Gobies migrate to river mouths as pulses of very dense groups of individuals, and that these pulses generally occur at night.

Cove, M.V., T.R. Simons, B. Gardner, and A. O'Connell. 2016. Co-occurrence dynamics of endangered Lower Keys marsh rabbits and free-ranging cats. The Wildlife Society, Annual Meeting, Raleigh NC.	October 2016	Marsh rabbit colonization was negatively associated with relative increases in the number of individual cats at each site over 1-2 years. Dynamic co-occurrence models also suggested that the two species are negatively associated spatially, but co-detections at sites were positively associated. These findings indicate that continued predator management in protected areas would likely benefit marsh rabbits as they re-colonize restored habitats.

Turbidity control in aquatic systems with polyacrylamide: assessing differences in formulation and resulting toxicity to native freshwater mussels. Biennial Symposium of the Freshwater Mollusk Conservation Society. March 22-27, St. Charles, Missouri.	March 2015	Polyacrylamide has become an effective tool for reducing suspended sediment and turbidity, but little is known about the effects of PAM on many freshwater organisms, and no information exists on the toxicity of PAM formulations to native freshwater mussels. Generally, we found that PAM concentrations typically recommended for turbidity control (1–5 mg/L), regardless of molecular weight or charge density, were not acutely toxic to the mussel species and life stages tested, indicating minimal ri
