Effects of sampling designs for remotely operated vehicles on fish abundance estimates	December 2025	The Washington Department of Fish and Wildlife (WDFW) uses a remotely operated vehicle (ROV) to monitor fish species that occur in complex benthic habitats with a goal of generating density estimates for groundfishes that are primarily of historical and current recreational and commercial fisheries importance. The variety of life histories, abundances, and habitat preferences of the suite of groundfish species in the survey area presents trade-offs when attempting to design efficient standardized multi-species surveys. Despite WDFW’s mandate to manage numerous groundfish species, targeting Bocaccio and Yelloweye Rockfish has been a primary driver of the ROV survey efforts. The project is a collaboration of researchers from the U.S. Geological Survey, the Washington Department of Fish and Wildlife, and the University of Washington. We are identifying how different ROV field methods capture target species with heterogeneous spatial distributions and how potential differences among methods influence density estimates. This study will directly inform standardization of ROV field survey operations relative to target species abundances and distributions for resource management agencies.	None
Investigating the influence of Artificial Light at Night on juvenile sockeye salmon behavior and predation risk in an urban lake	December 2026	Salmon and their predators are primarily visual feeders, but artificial light at night disrupts natural light cycles by extending low-light conditions, increasing nocturnal light levels, and obscuring seasonal light fluctuations. As artificial light at night increases in urban watersheds, even a small shift in night time light could create large changes in fish distribution, behavior, and foraging vulnerability for at-risk sockeye salmon. Our findings will help fishery managers quantify the current predation pressure on juvenile salmon populations and identify areas for light mitigation. This data will provide crucial insights into the impact of artificial light on salmon behavior and distribution through daily, lunar, and seasonal cycles.	None
A comprehensive movement model for returning Steelhead in the Columbia River Basin	March 2025	The Columbia River Basin is a complex social-ecological system that has been significantly modified through the construction of hundreds of dams, with major impacts to wild salmonids. The transformation of a free-flowing river into a highly controlled series of reservoirs requires that intentional decisions be made about how to manage the flow of the river when it comes to balancing the needs of food, energy, and fish. This problem is further complicated by the many different species of fish, their different life stages, and different timings of migration. We are using 20 years of data to jointly model the impacts of climate and hydropower on returning Steelhead from their arrival at Bonneville Dam to their final detection in the basin. This approach allows us to understand the relative importance of different factors in determining the fates of returning adults, which is key to informing management actions that are effective for population recovery, cost-effective, and responsive to a changing climate.

Examining spatiotemporal patterns of marine debris in Puget Sound, Washington	June 2025	Marine debris is a persistent pollution issue in coastal communities around the world. Man-made litter and material that is lost or discarded in the ocean can accumulate and endanger marine life (eg, lost fishing gear that "ghost" fishes). Since 1987, the Washington Department of Fish and Wildlife (WDFW) has conducted annual trawl surveys to assess bottomfish populations in Puget Sound. In addition to documenting the organisms that inhabit the seafloor, these surveys also identify and record debris caught in each trawl, including aluminum, plastic, glass, and derelict fishing gear. Among other details, the WDFW’s extensive records include the region, depth, type, and abundance of debris to give the best picture of what man-made materials are found on the seafloor of Puget Sound. Despite continued collection, this dataset has not yet been formally analyzed. This project aims to investigate the distribution and abundance of marine debris throughout various regions of the Sound over time. Analysis of this dataset will aid in the understanding and awareness of marine debris in Puget Sound, which is vital to informing effective clean up and prevention efforts to make community waters cleaner and safer for both humans and marine life.

Integrating community science data with long-term aerial surveys to understand seasonal and long-term shifts in marine bird use of Puget Sound	January 2026	Nearly two decades after the formation of the Puget Sound Partnership brought an increase in funding and management attention to Puget Sound recovery, an indicator of ecosystem health for Puget Sound, the abundance of marine birds, remains imperiled. There is an urgent need to assess the impacts of changing environmental conditions on marine bird populations in Puget Sound, as many species are already declining or vulnerable. Through funding from Washington Sea Grant, the WACFWRU is partnering with the Puget Sound Bird Observatory and Washington Department of Fish and Wildlife to carry out an integrated assessment of wintering marine birds in Puget Sound. We will integrate Washington Department of Fish and Wlidlife data with a long-term community science dataset to better understand marine bird abundance, growth, and distributions throughout the winter, to inform conservation of these species and their habitats.

Washington pygmy rabbit conservation planning process	March 2025	The Columbia Basin population of pygmy rabbits (<i>Brachylagus idahoensis</i>) is both federally and Washington-state endangered. Small population size, disease, fire, and habitat fragmentation are major threats to the population. We propose engaging managers, stakeholders, and experts in a structured decision making (SDM) process to identify a comprehensive recovery strategy for pygmy rabbits that involves clear management objectives, identification of a suite of recovery alternatives, and a modeling framework in which these alternatives can be evaluated. This work is being carried out in collaboration with Washington Department of Fish and Wildlife and the US Fish and Wildlife Service. The product of this process will be an actionable recovery strategy for Columbia Basin pygmy rabbits, along with identified next steps, including key information needs.	None
Modeling and conserving Streaked Horned Larks in Washington	December 2023	Streaked Horned Larks are a federally threatened and Washington state-endangered subspecies found only in Washington and Oregon. In Washington, the species relies on heavily fragmented grassland habitat in the South Puget Sound region. A better understanding of the dynamics of species that exist in highly fragmented habitats is a challenge in population ecology. For Streaked Horned Larks, this understanding could also help to inform reintroductions of the species. We are working with Washington Department of Fish and Wildlife, Ecostudies Institute, and other partners to develop an integrated population model for this species, which will allow for movement between habitat islands in the South Puget Sound region. We will then couple model output with expert judgments to evaluate a suite of proposed strategies for Streaked Horned Lark reintroductions. Reintroduction has the potential to be a valuable management strategy for Streaked Horned Larks, and information that will allow decision makers to choose amongst proposed reintroduction strategies can accelerate recovery of this species.

Conservation of Northwestern pond turtles in Washington	September 2029	Northwestern pond turtles are a state-endangered species in Washington and the US Fish and Wildlife Service recently proposed the species for federal listing. In Washington, the species' decline has been sharp, but there is a great deal of uncertainty regarding the relative importance of the factors that are putatively driving this decline. Having a better understanding of the threats and an approach for rigorously evaluating management actions will help to inform conservation of the species. We are working with the Washington Department of Fish and Wildlife to undertake a Structured Decision Making process. Through this process, we will develop a framework to inform conservation of the species in Washington and to identify the most important uncertainties that are restricting management. These uncertainties will be the focus of a graduate research project. The framework we develop, and the new research that will be designed to fill knowledge gaps in that framework, will help state and federal agencies to plan conservation for this species.

An evaluation of the effectiveness of restoration spending in the Columbia River Basin	August 2023	The decline in salmon and steelhead populations in the Columbia River Basin has been well documented, as have the decades-long, $9 billion restoration spending efforts by federal and state agencies. These efforts are mainly tied to Endangered Species Act (ESA) mandates for recovery of wild, naturally-spawning threatened or endangered fish species. The impact of these efforts remains poorly understood; many observers, including the federal courts, have long been concerned by the lack of evidence of recovery. Most studies evaluating restoration efforts have examined individual projects for specific species, reaches, or life stages, which limits the ability to make broad inferences at the basin level. This project involves researchers from Oregon State University. We are using historical information on fish abundance and associated restoration spending to evaluate the effectiveness of restoration activities in restoring ESA-listed salmon and steelhead. This information will be useful to regional management agencies in determining how best to spend limited recovery resources.

Maximizing returns on investing in barrier culvert removal in Washington State	January 2024	Across Western Washington, thousands of poorly-designed culverts at road crossings prevent migratory salmon from accessing potential habitat, hampering recovery efforts for declining populations. In 2013, a federal court found that barrier culverts in Washington violate tribal treaty rights and issued an injunction requiring their replacement. While the injunction only applies to state-owned culverts, thousands of additional barrier culverts are owned by local governments and private landowners, often within the same watersheds, generate inter-dependencies between barrier correction activities. The project is a collaboration of researchers from the University of Washington and the National Marine Fisheries Service. Our project will develop a consistent, data-driven framework for prioritizing fish passage barriers over multiple objectives, drawing from a rich literature on fish passage restoration plans that maximize return on investment. The decision support tool we develop will serve a coordinating function between barrier owners and managers by allowing the consistent comparison of alternative barrier correction, complementing ongoing efforts to restore fish passage in the state of Washington.

Evaluating the carrying capacity of pink salmon in Sitka National Historical Park	December 2025	Freshwater ecosystems supporting Pacific salmon exhibit natural and wide-ranging variability in the number of salmon they can support. In some areas, the carrying capacity is affected by hatchery-origin adults that stray from hatchery and instead return to nearby rivers and streams. The Indian River within Sitka National Historical Park once had returns of pink salmon numbering in the thousands. Following the construction of a nearby instructional hatchery that draws its water for egg incubation and juvenile rearing, many adults now "escape" the fishery and stray into the river, such that recent returns are two orders of magnitude higher. This project is a collaboration with scientists from the National Park Service (NPS), the Sitka Tribe of Alaska, the Sitka Sound Science Center, and Trout Unlimited. We will develop a model for evaluating a reasonable escapement goal for the river that also considers the effects of water withdrawals, which will help the NPS better manage pink salmon.

Improved monitoring of toxics in nearshore environments in Puget Sound, Washington	May 2023	Monitoring toxics in nearshore marine environments is important because this habitat is the interface between land and water. The Puget Sound Partnership’s (PSP) Leadership Council recently identified this as priority information need by authorizing the addition of nearshore toxics monitoring (using mussels) to the PSP’s Toxics in Aquatic Life Vital Sign indicators. Toxic contaminants have been monitored for almost 30 years in other Puget Sound species (flatfish, herring and salmon) in other habitats, but monitoring for toxics in the nearshore has only recently begun. Recovery goals for toxics typically mean reductions in contamination to levels that make the organisms safe for people to consume, or to levels that will not harm the animals. The design of this monitoring program will consider recovery goals specifically tailored to communities impacted by contaminants in the nearshore. The project is a collaboration of researchers at the Washington Department of Fish and Wildlife and the USGS Washington Cooperative Fish and Wildlife Research Unit. This project is intended to cut across otherwise disparate monitoring and recovery efforts, by joining ecological ideas with the social sciences to bring a more meaningful and environmentally just approach to ecosystem recovery. It will specifically seek out affected communities typically excluded from such decision-making, consider non-traditional concepts of health and vitality, and honor the full diversity of cultures using these resources.

The role of local ecological knowledge and perceptions in southern resident killer whale policy	June 2028	Southern resident killer whales are a major conservation concern in Washington. They evoke strong public opinions, but policy decisions are not always consistent with killer whale ecology. In this project we will use social science methods to improve our understanding of the relationship between killer whale ecology, policy, and decision-making, and inform state and federal managers to help improve outcomes for both people and killer whales.

Regional Program Development and Large Scale Restoration Planning, Interdepartmental science team participation, ecosystem restoration modeling, planning and ecological research (FY 09-10)	September 2010	In 2004, a research work order that was created and used to provide funding for the NST expired. The expired RWO included NST participation as well as specific technical products produced with significant contributions of NST members from the UW. Following this initial proposal, a second RWO for the period covering fiscal years 2007 and 2008, which is set to expire this year, was created. This current proposed RWO is a follow-on effort that supports NST participation, studies, analyses, and other contributions by the University of Washington professors, students and supporting University staff on the NST for fiscal years 2009 and 2010, the current planning horizon for the PSNERP feasibility study. The PSNERP study is expected to prepare a draft feasibility study within FY 2010. Under this proposal, the University of Washington is providing research support through personnel and labor to the Nearshore Science Team's development of a Puget Sound Restoration Program. UW effort includes development of related documents and products. It is an interdepartmental UW effort. The Research Professor Charles Simenstad (UW) will act as Principal Investigator and be responsible for coordination of UW participants and for product submittals. Additional UW personnel will be funded under the direction of Prof. Simenstad to participate on the NST and work on method development. This group includes other faculty and graduate students. Research Objectives: Research and development of ecosystem scale restoration models and products is the primary purpose of the NST. However, the NSTs interdepartmental makeup and the evolving nature of PSNERP research needs makes it necessary to maintain proper forums for scientific discussion and research dissemination. 1. Maintain a forum and process to advance scientific guidance, and provide analyses and products for nearshore Puget Sound ecology and restoration discussions and planning under PSNERP, and the WDFW, which serves as the Local Sponsor. The UW NST members will contribute their expertise and analytical skill toward the completion of the PSNERP restoration program by conducting studies, analyses and planning guidance in support of the COE feasibility study and furthering Puget Sound restoration science. 2. Participation by the University of Washington in Nearshore Science Team activities and as a cooperator with other agency representatives in selected NST working groups. 3. Conduct research and analyses on nearshore ecosystem restoration strategies and methods and prepare NST publications, reports and other work products, and conduct workshops and other science exchanges on selected PSNERP tasks in support of Objective 1. Research Goals: Specific research tasks in support of these general tasks will be provided through modifications to this agreement. These modifications will outline specific research objectives, products, graduate student responsibilities, staff time commitments and other costs, and any other coordination, equipment or travel needs. General tasks require both academic and applied research applications including: 1. Development and application of on-going PSNERP/NST research and analyses to inform PSNERP restoration planning research efforts on strategic restoration products, such as: a. Strategic Needs Assessment, UW shall provide faculty and graduate student support to development of regional analysis required for general understanding of appropriate restoration approaches at the Puget Sound scale. The SNA provides for discussion on overall restoration strategies for Puget Sound taking into account UW interdepartmental research on oceanographic conditions (Hood Canal) and aquatic sciences research to best implement an ecosystem scale restoration program. b. Future With and Without Project Conditions Analyses, Information systems research needed to assess benefits of Puget Sound restoration using scalable approach. Expand existing graduate student classroom experiences to develop methodology for forecasting Puget Sound changes without a system wide restoration programs. Results will be used to justify Federal funding expenditure and serve as key component of the Strategic Needs Assessment. c. Geospatial Database Research and Restoration Planning Complete GIS and information technology research following development of a large geospatial database on current, historic and future landscape changes. UW faculty and graduate students will work with other departments and outside agencies to establish analytical methods that can be used at the Puget Sound scale by multiple groups so that effective conclusions can be drawn. Results will be analyzed and integrated into the Strategic needs Assessment as part of the PNSER program. d. External Peer Review Develop and implement a peer review process for the Nearshore GI Study utilizing outside researchers and experts to fulfill Water Resources Development Act requirements. e.

Graduate student research has been integrated into PSNER/NST product development including support to research needs outlined under research goal 1. Specifically, graduate students supported by the PSNER program are conducting research on policy and political administration of restoration programs while others are researching the use of information technology into large restoration programs. 3. Attend NST meetings and associated NST working group meetings; and, participate in a series of conferences or workshops to be scheduled as mutually agreed upon. Purpose is to disseminate results of NST research and obtain regional input on PSNER/NST guidance and strategic work products.	None
Mechanisms of fish viral disease and immunity	September 2010	Many of the most important and destructive pathogens of finfish are viruses in the family Rhabdoviridae. The rhabdovirus Infectious hematopoietic necrosis virus (IHNV) is the most significant viral pathogen of salmonid fish hosts and it is endemic to nearly all Pacific watersheds of western North America. Numerous field isolates of IHNV have been characterized and found to fall into three major genetic groups, called genogroups U, M, and L. Geographic ranges of U and M genogroup IHNV overlap in much of the Columbia River basin. Individual strains are known to differ in virulence and show host-specific virulence, e.g. U genogroup IHNV has high virulence in sockeye salmon (Oncorhynchus nerka), but low virulence in rainbow trout (O. mykiss). Conversely, M genogroup IHNV has low virulence in sockeye salmon but high virulence in rainbow trout. The mechanistic basis of these virulence differences is unknown. This project will use various experimental approaches to explore and elucidate the basis of virulence of IHNV. This will include investigations of viral features and also host immune responses to both viral infection and vaccination against IHNV. In addition to well established endemic viruses such as IHNV, there are recently emerging viruses of great importance, such as the rhabdovirus Viral hemorrhagic septicemia virus (VHSV) in the Great Lakes. As time and funding permit researchers will explore viral and host factors associated with virulence of multiple strains of VHSV and possibly other important viruses that cause mortality in wild or cultured fish in North America. Objectives Objective 1. Investigate virulence and pathogenicity of important established and emerging fish viral pathogens Objective 2. Investigate viral fitness and mechanisms of viral virulence Objective 3. Characterize host immune response to viral infection Objective 4. Characterize vaccine efficacy and immune response to vaccination Methods Objective 1. Investigate virulence and pathogenicity of important established and emerging fish viral pathogens Virulence of different field strains of IHNV will be characterized in controlled wet-laboratory challenges. Variables will include different host fish species and/or stocks, different fish ages, different viral challenge routes (immersion or intraperitoneal injection), or different doses of challenge virus. Challenges will typically be done in duplicate groups of 20 fish, with mock-challenged groups to control for non-viral associated mortality. Virulence will be defined in terms of final cumulative percent mortality (CPM) after a 28 day observation period, and kinetics of mortality curves over time. As funding permits, virulence of different strains of important emerging fish viruses such as VHSV may also be examined, using strict containment in our Aquatic Biosafety level 3 wetlab when appropriate. The goal of this objective is to characterize variation in viral virulence and identify strains that reproducibly demonstrate high and low virulence under specific controlled conditions. Objective 2. Investigate viral fitness and mechanisms of viral virulence For viruses fitness is defined as the ability to replicate and produce infectious progeny in a given environment. Replication of different virus strains will be assessed and compared in in vivo growth curve studies in which fish are infected with individual strains in batch and then separated into individual beakers to prevent cross-contamination. At specified time points 1-10 days post-infection 5-15 fish will be euthanized and viral progeny will be quantified in each fish using a quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR) assay for viral RNA. Rate of replication and maximum yield attained will be measures of viral fitness: our hypothesis will be that more virulent viruses will have higher fitness, i.e. they will replicate faster and/or to higher yield. Competitive fitness of selected pairs of virus strains will also be tested in co-infections to see if higher virulence viruses out-compete lower virulence viruses in the same host. These assays will require development of genotype-specific qRT-PCR assays to quantify each viral strain within mixed strain progeny populations. Objective 3. Characterize host immune response to viral infection Selected fish host species will be infected with high and low virulence IHNV strains and at specified time points subgroups of fish will be euthanized to collect samples of various tissues (e.g. kidney, spleen). Innate immune responses of these fish will be characterized by extracting RNA from these tissue samples and conducting qRT-PCR assays for up-regulation (or down-regulation) of innate immune genes such as interferons, interferon-stimulated genes (ISGs, such as Mx), and virally-induced genes (VIGs) such as Vig-1 and Vig-8. Adaptive immunity will be similarly profiled at later time points with assays for immune-related genes such as IgM, T-cell receptor, Il-10 and Il-12. The goal of this objective is to profile the immune responses qualitatively (which genes are turned on) and quantitatively (magnitude of increase in gene expression). Adaptive immunity will also be assessed by quantifying IHNV-specific neutralizing antibody (NAb) titers and NAb specificity in sera collected from fish 6-12 weeks post-infection. We hypothesize that the immune responses to high and low virulence virus strains will differ in ways that are informative for understanding the basis of virulence. As funding permits, immune responses to other viral species may be characterized for comparison with findings from IHNV studies. Objective 4. Characterize vaccine efficacy and immune response to vaccination Although vaccines for fish rhabdoviruses have been explored since the 1970s there are no commercially available vaccines for IHNV or VHSV in widespread use. In the last ten years novel vaccines comprised of plasmid DNA carrying the viral surface glycoprotein (G protein) have been shown to be exceptionally successful in eliciting protective immunity against IHNV or VHSV. We have constructed DNA vaccines carrying G protein genes from both U and M genogroup IHNV strains. Efficacy of these vaccines will be compared in different fish hosts, and the innate and adaptive immune responses stimulated by the vaccines will be characterized and compared as described in objective 3. The results of these experiments will allow us to compare the immune responses to vaccination with the responses to viral infection, and will contribute to continued development of these novel vaccines for eventual use in cultured fish.

Managing the Nations Fish Habitat at Multiple Spatial Scales in a Rapidly Changing Climate	March 2013	Need-- The goal of this project is to provide guidance to aquatic resource managers and decision makers for managing fish habitat and their associated aquatic communities. We propose toprovide information and tools that will facilitate the conservation and management of aquatic resources in the face of global climate and land-use change. Our proposed research will inform management and conservation efforts performed at multiple spatial scales, ranging from the regional prioritization of critical aquatic habitats to local population dynamics of ecologically and economically valuable fish species. Successful conservation and management of aquatic habitat and the fisheries within these systems is predicated upon the ability to forecast future environmental change (USGS Circular 1309, 2007). Water needs for consumption and energy production, agricultural and urban development, climate change, and invasive species endanger freshwater habitat and their associated biological communities at levels greater than terrestrial and marine systems (Dudgeon et al. 2006). As a consequence, fish habitat quality and quantity and subsequently aquatic species are declining nationwide (Abell et al. 2000; Jelks et al. 2008). An important first step in managing the nation's fish habitat is a comprehensive assessment of the current state of habitat at national, regional and local scales. Assessment of habitats that are most in need of management and assessing the threats associated with these habitats, will allow managers to better prioritize conservation and restoration actions. A robust assessment should allow for an understanding of the current state of aquatic habitat from the national to regional scales, and ultimately to the local management scale. Assessments, however, represents a static picture of the past; and successful management of aquatic habitat will require a capacity to forecast changes in habitat as a result of future changes in climate, land-use, and other natural and anthropogenic factors. Successful conservation and management will need to answer the fundamental question, what are the critical habitat and resource strategies to conserve in order to maintain freshwater biodiversity, freshwater fisheries and ecosystem function in the future? Potential climate-induced changes in the biophysical processes that drive freshwater ecosystems coupled with human-induced, land-use change have resulted in declining aquatic habitat condition nation-wide (Poff et al. 2002; Allan 2004). Coupling multiscale habitat evaluation with downscaled climate information will allow managers to understand where critical resources must be protected and prioritize future management actions. While downscaled climate models are urgently needed, the current tools that have been developed are at much broader scales and have limited utility at regional and local levels. Atmosphere-Ocean General Circulation Models (AOGCMs) have proven useful to predict the potential impacts of climate change at large spatial scales (Bolin et al. 1986; Melack et al. 1997). However, there is a mismatch between the broad-scale predictions from these models and the more local management of fish and aquatic habitats. Development of methods that integrate forecasts of land-use and climate change for prediction of changes in aquatic habitat within nested national, regional, and local scales are urgently needed. The goal of this project is to develop a multi-scale assessment of the current and future status of fish habitat (and predicted biological responses) under scenarios of projected climate and land-use changes at national, regional, and local scales. We will develop: 1) a coarse assessment of vulnerable habitat across the nation useful to National Fish Habitat Action Plan (NFHAP) board and federal national offices, 2) medium resolution information across four regions appropriate for NFHAP partnerships and state agencies, and 3) relatively high resolution data about current and future habitat status so that local managers and stakeholders can identify the appropriate spatial scale where lentic and lotic habitats and associated biological communities are most vulnerable to climate and land-use changes.

Gut Content Analysis of California Gulls Foraging in the Columbia River	February 2010	Objectives Provide lowest-taxon data on the gut contents of California Gulls foraging in the Columbia River. Identify all salmonids in the gut contents to species. Methods Diet analysis on 128 California gull stomachs will be performed. Gut contents have already been removed from carcasses, and are currently stored frozen in Whirlpacks. Initial soft tissue identifications have been completed, but will need to be verified. We will produce three things: 1) Hard tissue ID including salmonids to species and other fish to genus or the level that would allow us to separate them from other fish in the Columbia River system near John Day Dam. It is hoped that using otoliths will provide a clear distinction between sub-yearling and yearling Chinook. 2) Verification of completed soft tissue ID including determination to species. 3) Prey items by number, mass and percent biomass. Non-fish items may be lumped into groups (e.g., aquatic insects). All methods used in this project will follow those described in Wiese et al. (2008) and Parrish et al. 2006a), and will use a key specifically designed to identify otoliths and fish cranial bones in the gut contents of piscivorous birds (Parrish et al. 2006b).	None
Forecasting the geography of fish invasions in the lower Colorado River basin	July 2011	Invasive species have caused major global change, harming indigenous species and communities throughout the world and inflicting enormous economic and ecological damage. Anticipating the future threatens posed by invasive species requires a predictive, proactive approach that forecasts potential distributions to further inform the identification and prioritization of critical conservation areas and endemic species at risk. Innovative analytical approaches, coupled with fast micro-computers, enable reliable large-scale nonparametric analyses to predict species distributions from geographical and ecological data. The attached research proposal addresses this pressing need by developing predictive models for forecasting the potential distributions of freshwater non-indigenous fish species in the Lower Colorado River Basin. This project addresses 3 fundamental questions that are critical for effectively managing invasive species in the Lower Colorado River Basin: (1) Will non-indigenous species already established continue to spread throughout the basin, or do they already occupy most of their potential range?; (2) If they continue to spread, what regions of the basin are likely to experience the greatest rates of invasion?; and (3) Do regions of high invasion susceptibility contain highly diverse and vulnerable endemic fish faunas? Products from this research contribute directly to the USGS Aquatic GAP Program by providing a quantitative framework for informing the selection of conservation priorities and identifying high priority surveillance locations aimed at the early detection of fish invasions and minimizing the future ecological impacts on native fish diversity. More generally, this project will provide a general framework for how non-indigenous species (and other forms of biological and environmental change) can be better incorporated into current and future Aquatic GAP programs. Research Objectives � Anticipating the future threatens posed by invasive species requires a predictive approach that forecasts potential distributions to further inform the identification and prioritization of critical conservation areas and endemic species at risk. Such an approach would integrate the understanding of invader dynamics and the ecological interactions between the invader and natural ecosystems. These models would serve as the basis for specific strategies to prevent the further invasion and adverse impacts of non-indigenous species. This project addresses 3 fundamental questions (listed above) that are critical for effectively managing the invasion of the Lower Colorado River Basin by non-indigenous fishes Practical questions such as these about the control and management of non-indigenous fish species require quantitative models that forecast their potential distribution in the Lower Colorado River Basin. This project will develop predictive models for non-indigenous fishes with the aim of forecasting potential distributions throughout the Lower Colorado River Basin as a function of habitat suitability and proximity to sources of human introduction. Products from this research with lead to preventative measures and pro-active management strategies that can be implemented before non-indigenous species have become established. Research Approaches � Regional conservation planning for the Lower Colorado River Basin requires knowledge about the potential spread and impact of non-indigenous fish species. These strategies should be based on the analysis of large-scale, long-term datasets, which when combined with small-scale experimental studies, will provide complementary approaches to better understand both historical and current distributional patterns of non-indigenous species. Broad-scale studies provide the foundation for proactive conservation planning by identifying patterns and rates of spread. This project requires knowledge of native and non-native species distributions, and ecogeographical layers describing natural and human-impacted features of the environment, in particular, patterns of landuse and altered flow regimes associated with dams. In collaboration with the Lower Colorado River Basin Aquatic GAP this data will be collected and synthesized. Habitat-suitability or niche-based modeling techniques relate species point occurrence records to geographic information about the ecological characteristics of the landscape to produce a hypothesis about which ecological features are within a species' niche and which are not. The ecological niche model can then be projected onto landscapes to identify regions that present ecological conditions inside and outside of the species' niche, producing predictions of potentially suitable habitat distributions (Peterson 2003). I will use Ecological Niche Factor Analysis (ENFA, Hirzel et al. 2002) to model habitat suitability and the potential distributions of non-indigenous freshwater fishes in the Lower Colorado River Basin as a function of ecogeographical and human-related variables. ENFA is a method that quantifies the niche occupied by a species by comparing its distribution in ecological space with the environmental characteristics of the entire study area.	None

Evaluation of US Army Corps of Engineers Habitat Restoration Sites	December 2010	A number of habitat restoration sites in the lower Duwamish Waterway in Seattle, Washington have been extensively studied under previous Research Work Orders (RWOs) (Cordell et al., 1994, 1995, 2001, 2003), to determine how they function with respect to use by juvenile salmonids and production of invertebrates that provide the salmon with food. In 2008, the University of Washington Wetland Ecosystems Team (UW-WET) established a RWO with the U.S. Army Corps of Engineers (USACE) to investigate ten additional habitat restoration sites in order to evaluate their biological function and to enable an initial comparison of them to other better studied sites in the system. Work on these sites included biological sampling in cases where it had not been previously done, synthesis of pre-existing data reports, and an evaluation of each site with regard to the stated restoration goals (Armbrust et al. 2008). Additional such surveys were conducted for the USACE in 2009, at five sites (Armbrust et al. 2009). The goal of this project is to conduct similar literature surveys, site visits, and sampling at four additional restoration sites, which will include collection of new biological data where appropriate, and evaluation of each project with respect to original project goals. This data will be valuable in providing information about the restoration sites that can be used to compare to previously evaluated sites, and allowing for a standardized evaluation of the present status and biological function of each site.

This data will be valuable in providing information about restoration sites above the waterway and in contextualizing the more downstream sites that have been previously sampled extensively. Work common to all sites: - reports related to each restoration project will be summarized - conduct a thorough walk through of each site - Site specific work will be conducted in the following areas: - Lake Washington gravel nourishment area - Seahurst Park seawall removal site - Green River large woody debris site - Uper Green River "Humphrey" Log Jam For each site a separate summary of the monitoring data available as well as the results of our own monitoring efforts will be prepared. Where possible, we will evaluate the site regarding success in meeting its goals. We will also provide recommendations to improve site function if appropriate.	None
Estimates of Changing Daily Precipitation Intensity and Flood Risk in the Pacific Northwest Using Regional Climate Simulations	June 2011	The study will provide crucial data resources to support ongoing biological research in both terrestrial and aquatic ecosystems affected by high flows. These include extensions of current research on aquatic ecosystems impacted by river scour, channel morphology, and influx of woody debris (e.g. associated with the 20-year flood). Changing sediment source and transport regimes in watersheds experiencing the combined effects of potentially changing precipitation intensity, retreating glaciers, loss of snowpack, changing fire risks, and vegetation changes are important factors affecting coastal ecosystems in sensitive rivers such as the Skagit and Nisqually Rivers in the Puget Sound basin. Likewise, impacts to primary productivity in the coastal ocean are linked to sediments and associated nutrients delivered primarily by high flow events. Aquatic ecosystem impacts related to landslides and culvert failure in forest roads within National Park boundaries ultimately affect instream habitat for aquatic biota, and evaluations of species recovery efforts, especially for salmonids. Flooding is an important factor affecting terrestrial wetlands and is the subject of studies examining impacts to amphibians. At large spatial scales, the effects of changing flood risk in the Columbia River basin (and potential changes in water management for flood control) are both important inputs to ecosystem models used by the National Marine Fisheries Service (and others) to assess salmon recovery plans. Some collaborating federal and state agencies involved in these efforts include the U.S. Geological Survey, National Marine Fisheries Service, The Nature Conservancy, American Rivers, Trout Unlimited, U.S. National Park Service, U.S. Fish and Wildlife Service, WA State Dept. of Ecology, Skagit River System Cooperative, Northwest Power and Conservation Council, U.S. Bureau of Reclamation, U.S. Army Corps of Engineers. Scope of Work 1. Analyze ensemble of regional climate simulations to detect changes in extreme events relevant to flood risk. This analysis would include parameters such as changes in precipitation intensity, storm inter-arrival times, frequency of rain-on-snow, etc. 2. Develop and refine downscaling approaches for application to the regional climate model 3. Create daily time stephydrologic model driving data sets for selected future time periods based on downscaled regional climate model simulations 4. Run and archive hydrologic model simulations 5. Estimate associated flood risk for 297 CBCCSP sites 6. Create web-based archive of results. 7. Publish a journal article.	None

2010 Sampling for Elliott Bay/Duwamish Restoration Program Monitoring Project: Invertebrate Sampling	December 2011	This project is part of an ongoing research effort to understand how invertebrate prey resources colonize and use restored wetland habitats in the Duwamish River estuary, and industrialized waterway. The four sites being studied in this project consist of created channels, small embayments, and transplanted vegetation strata that were constructed between 2000 and 2006. In collaboration with the USFWS, researchers at the University of Washington (UW) have monitored fish and invertebrate populations four times since their construction. This project adds an additional year of invertebrate sampling at the sites, which will add to our understanding of the how biological function develops at restored sites. Research Objectives and Methods The purpose of this work is to collect invertebrate data for the Elliott Bay/Duwamish Restoration Program Monitoring Project, at 4 restoration sites and 2 reference sites on the Duwamish River in Seattle, Washington. Invertebrate samples are collected once per month from April through June. The invertebrate sampling will be conducted as part of a monitoring project under the Elliott Bay/Duwamish Restoration Program (EBDRP). The EBDRP Panel was established as part of a 1991 consent decree between the City of Seattle, Metro (now King County Department of Natural Resources) (DNR), and natural resource trustees . The restoration projects' construction and monitoring have been under the sponsorship and guidance of the EBDRP Panel of Managers, comprised of the City of Seattle, King County DNR, and the natural resource trustees, and follow the Intertidal Habitat Projects Monitoring Program monitoring plan (EBDRP 2000). The EBDRP project is a ten-year monitoring plan designed to determine if physical success and biological success criteria identified in the monitoring plan's restoration goals are being met. Monitoring Tasks 1. Collect fallout insect traps and invertebrate core samples at restoration and reference sites once per month from April through June. Identify invertebrates to species for taxa known to be important to juvenile salmonids and to order level for the remainder. Invertebrate Sampling Specific Tasks 1. Deploy and collect five fallout insect traps (tubs and platforms) in the estuary at each restoration site (Hamm Creek Estuary, Herring's House, Kenco, and North Wind's Weir) and respective reference site. 2. Collect 10 core samples at the restoration sites and their respective reference sites. 3. Identify invertebrates from the samples. Taxa known to be important to juvenile salmonids are identified to species and enumerated; the remainder is identified to order level	None
Integrating social tolerance into wolf habitat suitability models	December 2024	As gray wolves (<i>Canis lupus</i>) recolonize Washington state, they provoke strong, polarized responses among the state’s diverse human communities. While numerous studies have investigated the unique reaction of people to wolves and wolf management, managing wolves and human-wolf interactions remains challenging, and new methods in the environmental social sciences offer great promise in revealing patterns and supporting management. In this study, we will work with the Washington Department of Fish and Wildlife in three new methodological domains that have been urgently called for but rarely applied in the scientific literature. These domains are 1) longitudinal studies of attitudes and perspectives over time in an area experiencing recolonization; 2) mapping social phenomena to complement ecological understandings of habitat suitability and connectivity; and 3) including robust understandings of attitudes and values in science communication. Taken together, these methods can offer insights at local and broad scales and help identify systems under stress and prioritize management. The support provided by this funding will train a graduate student investigator in this important but understudied research domain and will directly lead to the production of a dissertation chapter.

Proactive development of CWD outreach, education, and policy to guide disease management in Washington	August 2026	The mission of the Washington Department of Fish and Wildlife (WDFW) is to preserve, protect, and perpetuate the state’s fish, wildlife, and ecosystems while providing sustainable fish and wildlife recreational and commercial opportunities. This mission represents the deeply held value of connection with the natural world that all Washingtonians share and forms the basis of the Department’s commitment to respond to significant risks to the health of the state’s native wildlife.

Assessing threats to Cascade red foxes in Washington	September 2025	The Cascade red fox (CRF) is one of the rarest and most genetically distinct carnivores in North America. Today, CRF appear to be absent from the North Cascades and are found primarily in Washington’s South Cascades including Mount Rainier National Park (MORA) and surrounding wilderness. A lack of information about threats to CRF, and the lack of a process for identifying and evaluating potential conservation actions, is complicating efforts to conserve this state-endangerd species. In this collaborative effort with partners including the National Park Service and Washington Department of Fish and Wildlife, we are combining existing data and new radio-tracking data to understand effects of threats on fox movements and demography. Based on results, we will engage partners in a decision-making process to identify and evaluate management actions. This work will inform ongoing conservation of CRF throughout their range in Washington, including development of a recovery plan for CRF in Washington.

Today, CRF appear to be absent from the North Cascades and are found primarily in Washington’s South Cascades including Mount Rainier National Park (MORA) and surrounding wilderness. A lack of information about threats to the CRF, a candidate for listing in Washington, is complicating efforts to conserve it. In this collaborative effort with partners including the National Park Service and Washington Department of Fish and Wildlife, we are using a combination of existing scat and camera trap sampling, radio-tagging foxes, and interviews, to: 1) Develop estimates of density and survival of CRF in MORA and the surrounding area, and evaluate the effect of spatial covariates, including those related to threats, on density and survival, 2) Understand how coyotes influence CRF habitat use in MORA and the surrounding area, and 3) Use Indigenous and traditional ecological knowledge (TEK) to understand pre-colonization versus contemporary coyote distribution in the southern Washington Cascades. This work will inform ongoing conservation of CRF throughout their range in Washington.
Assessing threats to critical seabird foraging habitat in the Salish Sea	September 2024	Seabirds are recognized as critical indicators of oceanic conditions. However, in the Salish Sea, increasing threats to seabird foraging habitat are not well understood in terms of their potential effects on seabird populations. A better understanding of threats to seabird foraging habitat could guide regional efforts to conserve these habitats. This project is a collaboration of researchers across multiple organizations, including US Fish and Wildlife Service, Washington Department of Fish and Wildlife, and University of Washington. We are developing a model to understand foraging habitat selection by Pigeon Guillemots and Rhinoceros Auklets nesting at Protection Island, mapping critical foraging habitat for these species, and developing a model linking breeding outcomes with foraging conditions.

Evaluating the relative effects of top-down and bottom-up factors on declines in Lake Sammamish kokanee salmon	September 2024	Historically, Lake Sammamish, Washington supported three unique runs of kokanee (<i>Oncorhynchus nerka</i>), which provided important food and recreational fishing opportunities for nearby communities. By the 1970s, losses of spawning habitat in tributaries to the lake and degraded water quality within the lake itself led to large declines in kokanee numbers, and by the mid-1980s the early run of kokanee had collapsed and all recreational fishing had been stopped. This project is a collaboration with scientists from Trout Unlimited; the City of Issaquah, Washington; King County, Washington; People for Puget Sound; Save Lake Sammamish; the Snoqualmie Tribe; the Wild Fish Conservancy; Washington Department of Fish and Wildlife; and the U.S. Fish and Wildlife Service. Our goal is to assess how habitat loss, fragmentation, and modification combine with direct human influences to negatively affect the viability of kokanee populations in Lake Sammamish. We will work to understand how the predator and prey communities within the Lake Sammamish Basin interact to drive changes in population dynamics of kokanee salmon. Specifically, we will focus on the top-down roles of native and nonnative predators (e.g., cutthroat trout, small- and largemouth bass) and the bottom-up influence of zooplankton and macroinvertebrate prey. This research will directly inform recovery efforts for this species of greatest conservation need and culturally valuable resource.	Historically, Lake Sammamish, Washington supported three unique runs of kokanee (<i>Oncorhynchus nerka</i>), which provided important food and recreational fishing opportunities for nearby communities. By the 1970s, losses of spawning habitat in tributaries to the lake and degraded water quality within the lake itself led to large declines in kokanee numbers, and by the mid-1980s the early run of kokanee had collapsed and all recreational fishing had been stopped.

Five-year status review of yelloweye and bocaccio rockfish in Puget Sound	September 2021	The Endangered Species Act (ESA) requires periodic reviews of species that are listed as threatened or endangered to ensure that the listing is still accurate. Specifically, section 4(c)(2) of the ESA states that the Secretary shall: <i>Conduct, at least once every five years, a review of all species included in a list. Determine on the basis of such review whether any such species should be removed from such list, be changed in status from an endangered species to a threatened species or be changed in status from a threatened species to an endangered species.</i> Yelloweye rockfish (S<i>ebastes ruberrimus</i>), canary rockfish (<i>Sebastes pinniger</i>), and bocaccio (<i>Sebastes paucispinis</i>) within the Salish Sea (Puget Sound, Georgia Basin) were listed under the ESA in 2010 and the next 5 year review is scheduled to be finished in late 2021. Understanding the population status of these listed rockfish is necessary to 1) inform fisheries and habitat conservation management, 2) inform population targets identified in the Rockfish Recovery Plan (finished in 2017), and 3) potentially propose changing the listing status of these fishes under the ESA. Improving our understanding of population status will entail collating and analyzing data from a variety of data sources. This project is a collaboration with scientists from NOAA Fisheries and the Washington Department of Fisheries and Wildlife. We will conduct population assessments using contemporary and historical information for ESA-listed rockfish, which will help inform 5-year status review and assist NOAA Fisheries in its determination of the viability of these species.

Advancing sustainable shellfish aquaculture through machine learning and automated data collection on fish communities	December 2023	Washington is the nation’s leading producer of farmed clams, oysters, and mussels, contributing approximately $184 million to the State economy, supporting over 1,900 jobs, and supplying fresh shellfish to consumers around the globe. With such high cultural, economic, and ecological value, there is substantial demand for growth within the shellfish aquaculture industry. A key impediment to the sustainable expansion of shellfish aquaculture is understanding the ecological implications of converting nearshore habitat to shellfish production. Understanding how shellfish aquaculture functions as nearshore habitat, relative to uncultivated areas, will help resource managers overcome this barrier and assess potential tradeoffs when planning the sustainable expansion of shellfish aquaculture. In collaboration with researchers from NOAA Fisheries and shellfish growers in Puget Sound, we have used underwater cameras to document nearshore fish (including outmigrating salmonids) and crabs in both shellfish aquaculture and uncultivated nearshore habitats. Subsets of these video data were processed manually to address questions of aquaculture habitat use. Optimization of video processing will enable use of this technology to answer key questions about how fish are utilizing these nearshore habitats. We anticipate that the optimization of video processing will permit us to expand this collaborative, industry-supported data stream to improve our understanding of the ecological function of shellfish aquaculture, as well as inform public perception on the marine ecology surrounding these farms.

Understanding how shellfish aquaculture functions as nearshore habitat, relative to uncultivated areas, will help resource managers overcome this barrier and assess potential tradeoffs when planning the sustainable expansion of shellfish aquaculture. To better understand the ecological functions of these habitats, we need to examine not only which species are present, but how those species use each habitat. The goal of this study is to quantify the impacts (positive, negative, neutral) of shellfish aquaculture on foraging experiences of fish and crabs. We will collaborate with the National Marine Fisheries Service to examine (1) feeding behavior of these organisms using an extensive dataset of underwater video and (2) their trophic ecology (diets, isotopes) by sampling sites within the Salish Sea. Results from this work will inform decisions about the introduction of aquaculture in a system comprised of a diversity of seascapes and where considerable management attention is invested in conserving species that rely on nearshore waters and their essential habitats.

A simulation and case-study comparison of existing and spatio-temporal methods to apportion coastwide catch limits for subregional management	September 2022	The North Pacific Fisheries Management Council (NPFMC) sets Total Allowable Catch (TAC) for all stocks and complexes listed in several Fisheries Management Plans. Currently, harvest regulations occurring for strata within each stock are informed by applying a smoother of available (and often highly uncertain) area-specific survey indices. However, this approach can result in large interannual variability in strata-specific harvest regulations, especially for stocks that are more challenging to survey or surveyed less frequently. In this project, we will investigate multiple alternative approaches to determine apportionment of subregional groundfish harvest in the Gulf of Alaska.

Monitoring Tufted Puffins in the United States	December 2023	The Tufted Puffin – a seabird of the North Pacific Rim – has evinced steep declines off the west coast of the continental United States in recent years, but it is less clear that the species is declining in the northern portion of its range. Therefore, while the species’ range appears to be contracting, the overall trends in abundance are less clear. Lack of a coordinated monitoring plan across the range reduces the ability to make robust inference about trends and to investigate dynamics that may be driving changes in abundance and distribution. We are partnering with the U.S. Fish and Wildlife Service, Washington Department of Fish and Wildlife, and the University of Puget Sound to develop a monitoring program for the Tufted Puffin in five large marine ecosystems (LME; California Current, Gulf of Alaska, Aleutian Islands, East Bering Sea, North Bering - Chukchi Seas) that considers local sampling situations, and is designed to identify monitoring methods that will allow for robust inference across and within these five LMEs. The project output will be a detailed monitoring strategy for Tufted Puffin that can be implemented by partners across the range in California, Oregon, Washington, British Columbia, and Alaska.

Improving our tools for combating invasive species	September 2024	Freshwater ecosystems provide a range of important values in the Pacific Northwest, and invasive species represent key threats to those values. Management of invasive species requires managers to effectively allocate limited resources to suppression or eradication, requiring robust information about invasive population structure, distribution, and rate of spread, as well as the efficacy of control actions. Data integration is a powerful statistical approach that is rapidly developing in both theory and application, wherein multiple data streams are brought together through a shared data likelihood. There is a critical need for data integration methods designed to make the best use of available, but often highly variable, data on invasive species for use in effective management models. We are partnering with the USFWS Columbia Pacific Northwest and Pacific Islands Regions, and the University of Washington, to develop broadly applicable data integration and modeling approaches for invasive species, with a focus on two high priority species in the Pacific Northwest: flowering rush (<i>Butomus umbellatus</i>) and rusty crayfish (<i>Faxonius rusticus</i>). This project will inform joint monitoring and management programs for these species, and similar invasive species, in the Pacific Northwest, nationally, and beyond.

Assessing the precision of estimates of population vital rates for polar bears in Alaska	May 2021	Polar bears (<i>Ursus maritimus) </i>are a trust species managed by the U.S. Fish and Wildlife Service and protected under the Endangered Species Act and Marine Mammal Protection Act, and the ability to monitor these animals is key to status assessment and management. Polar bears in the Southern Beaufort Sea (SBS) subpopulation occur in areas of increasing Arctic development and rapidly changing habitat conditions, increasing the importance of high-quality monitoring data. We are collaborating with the Applied Physics Laboratory at University of Washington and the USGS Alaska Science Center to complete a power analysis to determine the statistical power to detect changes in survival and abundance under various monitoring designs. Using this information, the U.S. and Canada will be better able to identify cost-effective monitoring approaches for the SBS at a time when sampling the subpopulation is becoming increasingly difficult.

Assessing the fish community in the Chehalis River with occupancy models	June 2021	The Washington Department of Fish and Wildlife (WDFW) is conducting a project in the Chehalis River of southwest Washington to determine the effects of salmon- and steelhead- focused restoration efforts on other native freshwater fish. The goals of this study are to, 1) define a baseline from which WDFW can monitor changes in native fish occupancy following restoration actions, and 2) describe the relationship between native freshwater fish occupancy and habitat and landscape metrics. WDFW aims to develop a multi-site occupancy model to describe how the fish community is influenced by habitat or landscape metrics. This information will inform the design and location of future restoration projects.

Long-term seabird monitoring data analysis to update Channel Islands National Park seabird inventory and monitoring program and Inform management and conservation	June 2024	Established in 1980, Channel Islands National Park contains essential breeding grounds for at least fourteen seabirds and shorebirds. Seabirds were identified as one of the park’s monitoring Vital Signs to provide critical information about trends in natural resource conditions and a Seabird Monitoring Handbook was created in 1983 to guide priorities and objectives for the Seabird Monitoring Program. This handbook was updated in 1988. Since then, staff turnover and funding gaps have led to an inconsistent effort in monitoring by the park. More recently, the Channel Islands National Park Seabird Biologist, in coordination with the National Park Service's Mediterranean Coast Network Inventory & Monitoring Program, has identified the need to conduct a scientific review of the park’s seabird program. Furthermore, a recent monitoring plan assessment report by Point Blue Conservation Science identified seven focal seabird species plus one shorebird species to be prioritized in an updated monitoring program. The purpose of the project proposed here is to advance Channel Islands National Park's Seabird Monitoring Program by compiling all known digitally available datasets for the eight prioritized species and conducting species-specific in-depth program reviews following NPS guidelines and in coordination with Channel Islands National Park and the National Park Service's Inventory & Monitoring Program.

Evaluating sea duck detectability in the Puget Sound winter ambient monitoring program	May 2023	The Washington Department of Fish and Wildlife annually conducts a survey to monitor sea ducks in Puget Sound. This survey, the Puget Sound Ambient Monitoring Program, is critical to understanding status and trends of sea ducks on this continentally important wintering area, and also to informing management of the Washington sea duck hunting season. While relative abundance has been available from the survey, a lack of information on detection rates has made estimation of absolute abundance untenable. A 2012 effort led to collection of digital imagery to inform the estimation of detection; such estimates could be used to calculate absolute abundance from the survey. However, a lack of dedicated program staff has complicated efforts to complete the analysis for the 2012 data. The purpose of this project is to complete analysis of these data to produce a correction factor for sea duck detection in the sea duck survey in Puget Sound.

Integrated population model for black bears in Maine	May 2021	To assist the Maine Department of Inland Fisheries and Wildlife in developing a cost-efficient monitoring program to inform their black bear management, we are developing an integrated model that estimates spatially explicit population size, movement patterns, and demographic rates of the Maine black bear population. Integrated models (IMs) unite data from multiple sources that are informative about demographic variables. IMs offer several important advantages over analyzing single datasets by themselves. IMs can estimate parameters that are inestimable from single data sets and do so more precisely. Multiple datasets can also overcome biases present in individual datasets, thus leading to more accurate estimates. IMs also can make use of datasets collected for different monitoring purposes at different times and locations, uniting seemingly disparate information to offer multi-scale inference on population patterns. IMs are therefore an efficient way to understand wildlife population dynamics, including survival and recruitment processes by making best use of all available information.

Summarizing current knowledge of the factors influencing juvenile salmonid susceptibility to avian predation in the Columbia River Basin	June 2020	Avian predation has been identified as a factor that limits the survival of juvenile salmonids in the Columbia River Basin and addressing predation concerns is a component of Biological Opinions and Reasonable and Prudent Alternatives associated with the management of the Federal Columbia River Power System (NOAA 2008). Over the last two decades, numerous avian predation research, monitoring, and evaluation (RM&E) studies have been conducted to evaluate the impact of predation by Caspian terns, double-crested cormorants, and other colonial waterbirds on the survival of Endangered Species Act-listed juvenile salmonids in the Columbia River basin. In this project, we will be collaborating with Real Time Research, Incorporated to summarize results from past studies regarding tern and cormorant nesting ecology, inter-colony movements, dispersal, and predation impacts on juvenile salmonids in the Columbia River basin. A specific emphasis of this work is to summarize our current knowledge of the factors influencing juvenile salmonid susceptibly to avian predation in the Columbia River Basin including factors such as fish rear-type (hatchery, wild), run-timing, and size (fork-length).

Integrating data sources to characterize demographic responses of Columbia River salmon and steelhead to threats and management actions	May 2023	Much of the historical abundance and diversity of Chinook salmon (Oncorhynchus tshawytscha) and steelhead trout (O. mykiss) have been lost in the Interior Columbia River, which led to the listing of many populations under the Endangered Species Act. Recovery goals have not been achieved despite substantial efforts, and there is a need to better understand the effect of various threats and ecosystem drivers on population dynamics. Three factors are of particularly high interest: 1) the effect of the quality of freshwater habitats used for egg incubation and juvenile rearing; 2) the effect of broad-scale ocean conditions on marine survival; and 3) the effect of predation by marine mammals. To characterize how these factors affect population viability, we will develop an integrated population modeling framework for spring-summer Chinook salmon by combining count and mark-recapture data. In this approach, data streams related to survival or productivity will be integrated with data streams related to abundance to estimate demographic parameters with greater statistical precision and less bias than would otherwise be possible. These models will use previously collected data to characterize the role of freshwater habitat, ocean conditions, and marine mammal predation on the abundance, productivity, diversity, and viability of salmon and steelhead populations in the Interior Columbia River. This research will facilitate evaluation of the benefits of past habitat restoration actions, will support decisions about future actions, and will provide an assessment of population viability.

Evaluating and mitigating the effects of brown treesnakes on Guam's birds	June 2024	The brown treesnake is an invasive species on the island of Guam and is responsible for the local extinction of much of Guam’s avifauna. Control of brown treesnakes is critical to conservation of the remaining native fauna and to the eventual reintroduction of many native species. Monitoring of brown treesnake populations will be key to informing control and reintroduction activities. Refinement of field and statistical methodologies is needed to provide information on brown treesnake populations, and this information needs to be fit within system models to inform both control and reintroduction activities. The U.S. Geological Survey Washington Cooperative Fish and Wildlife Research Unit plans to undertake a multi-year collaboration with the U.S. Navy on Guam, in addition to the U.S. Geological Survey Fort Collins Science Center, and U.S. Department of Agriculture APHIS Wildlife Services, to develop methods for monitoring brown treesnakes and to fit that information within management models to inform both brown treeesnake control activities and reintroduction of native fauna.

Integrated abundance and movement models for marine mammals	March 2021	Capture-recapture and telemetry methods are frequently used to evaluate marine mammal density, habitat use, and movement, providing important information on sustainable harvest, the effects of a warming environment, and spatial and temporal overlap with commercial fisheries. In general, capture-recapture methods provide population-level demographic parameters, while telemetry methods provide individual level information on habitat use, movement, and behavior. Although the two approaches share information on population dynamics, the resulting data are generally analyzed separately, which can lead to inefficient estimators and substantial bias. We propose development of a framework for integrating spatial capture–recapture (SCR) and telemetry data to simultaneously estimate density, habitat use, and movement of marine mammals. Integrated SCR telemetry models have the potential to (1) address shortcomings of traditional capture-recapture methods; (2) allow estimation of abundance, density, movement, dispersal, and habitat selection using all available data; and (3) be applied across a variety of study designs used for marine mammal monitoring. We propose to develop SCR-telemetry models using capture-recapture and telemetry data for polar bears in the Chukchi Sea during the period 2008 – 2016. We also propose to use simulation methods to evaluate the performance of SCR-telemetry models and provide monitoring design recommendations of broad applicability to polar bears and other marine mammals. Improved monitoring methods are critical to obtaining accurate information on polar bear abundance and distribution, which is needed for management and conservation under national laws and international agreements, and SCR-telemetry methods show great promise for providing that information. More broadly, SCR-telemetry models provide researchers and managers with a framework to integrate multiple data types – including data from<br>emerging technologies (e.g., satellite tags, acoustic sampling, autonomous drones) – to improve the accuracy and efficiency of marine mammal monitoring programs across the Arctic.	There is an increasing need to identify population- and individual-level responses to rapid physical and biological changes in Arctic marine ecosystems. For Arctic marine mammals that range over large areas, reliable and efficient methods to estimate movement and demographic parameters are vital to evaluating ecosystem-level changes, population status, and subsistence harvest, and minimizing conflicts with humans and resource development. Advanced statistical models that accommodate the particular challenges of studying wide-ranging marine mammals are needed. This project is a collaboration between researchers at the Washington Cooperative Fish and Wildlife Research Unit, the US Geological Survey Patuxent Wildlife Research Center, the US Fish and Wildlife Service, and the University of Washington Applied Physics Laboratory. The goal of the work is to provide recommendations to management agencies such as the US Fish and Wildlife Service regarding data collection and analysis methods to improve knowledge of marine mammal, particularly polar bear, demography.
Restoration tools for Oregon silverspot butterfly	September 2020	USFWS plans to reestablish populations of the severely endangered Oregon silverspot butterfly on two National Wildlife Refuges (NWR) in Oregon and Washington. Maintaining suitable habitat for Oregon silverspot is challenging. Oregon silverspot larvae need high densities of their host plant, early blue violet to develop into adult butterflies and the violets are an early successional species that is outcompeted by invasive plants. The project goal is to support refuge managers in deciding whether two selective herbicides should be used to maintain native prairie in the presence of Oregon silverspot. As part of the project, laboratory research will be conducted, and a management model will be developed to inform managers of the impacts of treatment with herbicides on Oregon silverspot viability.

Understanding common loon distribution and abundance in Washington	December 2019	The Common Loon (Gavia immer) is a State Species of Concern in Washington. The species was once thought to be fairly common in both eastern and western Washington, but likely declined in the early decades of the 20th Century. Planning conservation efforts for the species is complicated by lack of information on the abundance and distribution of the species in Washington. <br><br>With this project, we aim to provide the State of Washington with information necessary to conduct effective, efficient, and affordable surveys for the species in the State. The project will involve 3 components: 1) understanding factors influencing site occupancy of loons in the State, based on existing State survey data as well as citizen science (eBird) data; 2) pilot testing a drone-based sampling method to determine detection probabilities as a function of effort; and 3) using information from components 1 and 2 to design a sampling strategy (including sampling methods and strata) and conduct a simulation study that will describe expected precision in occupancy estimates as a function of sampling effort and spatial coverage.

Yakima Basin Reservoir Food Webs	September 2015	The U.S. Bureau of Reclamation (USBOR) and the Washington State Department of Ecology (WSDOE), through the Office of Columbia River, worked with the Yakima River Basin Water Enhancement Workgroup to develop an integrated water resource management plan designed to balance irrigation, recreation, and conservation needs in the Yakima River Basin, Washington (USBOR and WSDOE 2012). To meet these objectives, the integrated plan proposed numerous alterations to the structure and operation of existing reservoirs and dams within the basin. Three individual projects identified in the integrated plan are currently undergoing project-level environmental review. These include: (1) the Kachess Drought Relief Pumping Plant (KDRPP), (2) the Keechelus-to-Kachess Conveyance (KKC), and (3) the Cle Elum Pool Raise. How these proposed water management alterations might impact food web structure and populations of sensitive species (i.e., bull trout Salvelinus confluentus) within these reservoirs remains a key uncertainty for the environmental review process. However, before potential impacts can be identified and assessed, a contemporary understanding of the food web structure of these reservoirs is needed. Information on the physical and biological characteristics of Kachess and Keechelus Reservoirs is most limited. The purpose of this study was to synthesize existing information with new data to fill key knowledge gaps regarding the physical environment, food web structure, and predator–prey interactions in Kachess and Keechelus Reservoirs as they relate to supporting the production of bull trout. This information will (1) help identify important trophic pathways (i.e., pelagic vs. benthic production) supporting adult bull trout in these reservoirs, (2) provide key baseline data needed to consider the suitability of these reservoirs as potential rearing habitats and migratory corridors for reintroduced anadromous salmonids, and (3) aid in the project-level environmental review for KDRPP and KKC.

Quantifying Pelagic Food Web interactions in Lake Tahoe-In search of a niche for re-introduction of Lahontan Cutthroat trout	September 2015	Despite past research on trophic relationships within Lake Tahoe, important information gaps remain concerning temporal-spatial interactions among pelagic fishes and invertebrates, especially with respect to how these interactions might influence the re-introduction of Lahontan cutthroat trout into the lake. We focused on identifying and quantifying the key pelagic food web interactions related to kokanee, other planktivorous fishes, mysids, and zooplankton to synthesize with previous data on predator-prey interactions with lake trout, in order to improve our understanding about the contemporary food web. This analysis supported hypotheses regarding the important trophic role of mysids as a predator regulating crustacean zooplankton, a competitor limiting growth and production of kokanee, and as an essential energy source supporting the predatory lake trout population. Thermal stratification mediates the spatial-temporal distribution and overlap of predators, prey, and competitors and thus can potentially influence the timing and magnitude of trophic interactions among key pelagic fish and invertebrates.

Abundance and Impact of predators on sockeye salmon in Lake Washington	June 2015	The Lake Washington fishery for sockeye salmon is an important recreational fishery in a large urban lake alongside Seattle. The fishery has been closed since 2006 due to insufficient spawning escapement by returning adult sockeye. Currently 94% to 99% of juvenile sockeye that enter the lake as do not survive to the presmolt stage in Lake Washington one year later. Previous studies have shown that predation by Cutthroat trout and Northern Pikeminnow could conceivably account for nearly all of the lake-phase mortality of juvenile sockeye, depending on the abundance and size structure of the predator populations in the lake. In addition, the populations of juvenile salmon and alternative prey (Longfin Smelt and Threespine Sticklebacks) potentially influence the variability in seasonal and annual predation mortality imposed on juvenile Sockeye Salmon. In order to properly assess the predatory impacts of coastal cutthroat trout and northern pikeminnow on juvenile Sockeye Salmon the study will accomplish the following two objectives: 1) estimate the abundance of previously identified important predators of juvenile sockeye in the lake (coastal cutthroat trout and northern pikeminnow), and to 2) quantify their predation on juvenile sockeye.

Upper Lewis River reservoir Food Webs & Anadromous salmon introductions	September 2015	Re-introduction of anadromous salmonids above previously impassable dams is becoming an increasingly common mitigation strategy in the Pacific Northwest. The reservoirs impounded by these dams create novel habitats that juvenile salmonids can use for rearing and migration corridors. Therefore, understanding how environmental conditions, seasonal food supply, competition, and predation influence potential growth and survival of juvenile salmonids will be important when evaluating the feasibility of proposed re-introductions above historically impassable dams. Temperature, food availability, and predation risk form vertical gradients determining growth and survival for fish in lakes and reservoirs. These gradients change on inter-annual, seasonal, and diel temporal scales and are strongly influenced by climatic variability, conflicting water demands and management. Temperatures associated with optimal growth and energy loss vary both among life stages and species, but the quantity, quality, and spatial distribution of available food resources can significantly alter these thermal responses. By combining data or projections of thermal stratification regimes with the vertical distribution of prey and bioenergetic capabilities of species and life stages of fish, we can formulate predictions about spatial-temporal overlap among prey, competitors and predators. When overlaid on life history requirements, we can identify potential bottlenecks to growth or survival and evaluate responses to climatic variability, water management, or new species.	None
Puget Sound Marine Survival-LLTK	June 2016	Size-selective mortality (SSM) is a significant force regulating recruitment of salmon. The life stage(s) and habitat(s) when and where SSM occurs can vary considerably among species, stocks, and life history strategies. Moreover, the relationship between size, growth, and condition in freshwater and marine life stages to overall life cycle survival is unclear for most stocks of salmon. The first months of marine growth are commonly regarded as a critical period for growth and survival. For ESA-listed Puget Sound Chinook salmon, an emergent result has been: 1) at least one of the critical growth periods occur during early summer rearing in epi-pelagic marine habitats; 2) that growth is limited mostly by food supply rather than by energetic quality of the diet or thermal regime; 3) higher growth and survival correspond with higher contributions of key prey like crab larvae. Linking stage-specific growth performance and SSM offers a promising avenue for diagnosing the primary factors that affect growth and survival. The timing and relative magnitude of SSM can be determined by serial sampling of size distributions over a progression of life stages using both direct measurements of body size and back-calculated estimates from scales. Disproportionate reductions in the contribution of smaller members to subsequent life stages, especially to adult returns, can be used to determine the timing and magnitude of SSM and identify critical periods of growth and survival. We can then diagnose which factors most affect growth during critical periods through bioenergetics modeling simulations that are linked to directed sampling of diet, growth and environmental conditions. This approach could potentially improve run forecasting and focus restoration efforts.	None

Webster AJ, Douglas TA, Regier P, Scheuerell MD, Harms TK. Multi-scale temporal patterns in stream biogeochemistry indicate linked permafrost and ecological dynamics of boreal catchments. Ecosystems 25: 1189–1206 \| Abstract	October 2021	Temporal patterns in stream chemistry provide integrated signals describing the hydrological and ecological state of whole catchments. However, stream chemistry integrates multi-scale signals of processes occurring in both the catchment and stream. Deconvoluting these signals could identify mechanisms of solute transport and transformation and provide a basis for monitoring ecosystem change. We applied trend analysis, wavelet decomposition, multivariate autoregressive state-space modeling, and analysis of concentration-discharge relationships to assess temporal patterns in high-frequency (15 min) stream chemistry from permafrost-influenced boreal catchments in Interior Alaska at diel, storm, and seasonal time scales. We compared catchments that varied in spatial extent of permafrost and fire history to identify biogeochemical signals characteristic of these regimes. An unburned catchment with high spatial extent (54%) of permafrost was characterized by increasing nitrate concentration through the thaw season, an abrupt increase in nitrate and fluorescent dissolved organic matter (fDOM) and declining specific conductivity in late summer, and flushing of nitrate and fDOM during summer rain storms. In contrast, these patterns were absent, of lower magnitude, or reversed in catchments with lower permafrost extent (<19%) and recent fire. Solute dynamics revealed a positive influence of permafrost on fDOM export and the role of shallow, seasonally dynamic flowpaths in delivering solutes from high-permafrost catchments to streams. Lower spatial extent of permafrost resulted in static delivery of nitrate and limited transport of fDOM to streams. Shifts in concentration-discharge relationships and seasonal trends in stream chemistry toward less temporally dynamic patterns might therefore indicate reorganized catchment hydrology and biogeochemistry due to permafrost thaw.
Warlick, AJ, Johnson, D., Gelatt, T., Converse, SJ. 2022. Environmental drivers of demography and potential factors limiting the recovery of an endangered marine top predator. Ecosphere 13:e4325. \| Abstract	December 2022	Understanding what drives changes in wildlife demography over time is fundamental to the conservation and management of depleted or declining populations, though making inference about the intrinsic and extrinsic factors that influence survival and reproduction is challenging as they can change over time and space. Here we use almost 20 years of mark-resight data from 2000-2018 to examine the effects of environmental variability on age-specific survival and natality for the endangered western distinct population segment of Steller sea lions (<i>Eumetopias jubatus</i>) in Alaska, USA. Though this population has been studied extensively over the last four decades, the causes of divergent abundance trends that have been observed across the range of this population remain unknown. We developed a Bayesian multi-event mark-resight model that accounts for female reproductive state uncertainty. Results indicated that survival rates for male pups (0.44; 0.36-0.53), female yearlings (0.63; 0.49-0.73), and male yearlings (0.62; 0.51-0.71) born in the western portion of the range, estimated here for the first time, were lower than those estimated for male pups (0.69; 0.65-0.74), female yearlings (0.76; 0.71-0.81), and male yearlings (0.71; 0.65-0.78) born in the eastern portion of the range. Additionally, pup mass had a positive effect on pup survival in the eastern portion of the range and a negative effect in the western portion of the range. Local and basin-scale oceanographic features such as the Aleutian Low, the Arctic Oscillation Index, the North Pacific Gyre Oscillation, chlorophyll concentration, upwelling, and wind in certain seasons exhibited correlations with vital rates. However, strong inference is challenging given that relationships between ocean conditions and an adaptive top predator in a highly dynamic ecosystem are exceedingly complex. This study provides the first demographic rate estimates for the western portion of the population range where abundance estimates continue to decline. This work can inform ongoing research and management and will advance efforts to identify factors driving regionally divergent abundance trends with implications for population-level responses to future climate variability.

Identifying demographic and environmental drivers of population dynamics and viability in an endangered top predator using an integrated model. Animal Conservation 27:240-252. \| Abstract	April 2024	Knowledge about the demographic and environmental factors underlying population dynamics is fundamental to designing effective conservation measures to recover depleted wildlife populations. However, sparse monitoring data or persistent knowledge gaps about threats make it difficult to identify the drivers of population dynamics. In situations where small, depleted populations show continued evidence of decline for unknown reasons, integrated population models can improve our understanding of demography, provide fundamental insights into factors that may be limiting recovery, and support conservation decisions. We used mark-resight and aerial survey data from 2004-2018 to build an integrated population model for the Cook Inlet population of beluga whales (<i>Delphinapterus leucas</i>), which is listed as endangered under the U.S. Endangered Species Act. We examined the relationships between beluga vital rates and prey availability and environmental conditions and conducted a population viability analysis to predict extinction risk across a range of hypothetical changes in beluga survival and reproduction. Our results indicated that while survival of breeding females (0.97; 95% CrI 0.95-0.99) and young calves (0.92; 0.80-0.98) was relatively high, survival of non-breeders (0.94; 0.91-0.97) and fecundity (0.27; 0.21-0.35) may be depressed. Furthermore, our analysis indicates that if vital rates and environmental variability remain similar to estimates from the latter part of the study period, the population will likely continue to decline, with a 19-32% probability of extinction in 150 years. Our model framework highlights the utility of integrated population modeling for identifying factors contributing to the failure of protected populations to recover.

Ward EJ, Marshall KN, Scheuerell MD. Regularizing priors for Bayesian VAR applications to large ecological datasets. PeerJ \| Abstract	December 2022	Using multi-species time series data has long been of interest for estimating inter-specific interactions with vector autoregressive models (VAR) and state space VAR models (VARSS); these methods are also described in the ecological literature as multivariate autoregressive models (MAR, MARSS). To date, most studies have used these approaches on relatively small food webs where the total number of interactions to be estimated is relatively small. However, as the number of species or functional groups increases, the length of the time series must also increase to provide enough degrees of freedom with which to estimate the pairwise interactions. To address this issue, we use Bayesian methods to explore the potential benefits of using regularized priors , such as Laplace and regularized horseshoe, on estimating interspecific interactions with VAR and VARSS models. We first perform a large-scale simulation study, examining the performance of alternative priors across various levels of observation error. Results from these simulations show that for sparse matrices, the regularized horseshoe prior minimizes the bias and variance across all inter-specific interactions. We then apply the Bayesian VAR model with regularized priors to a output from a large marine food web model (37 species) from the west coast of the USA. Results from this analysis indicate that regularization improves predictive performance of the VAR model, while still identifying important inter-specific interactions.

Social Effectiveness and Human-Wildlife Conflict: Linking the Ecological Effectiveness and Social Acceptability of Livestock Protection Tools. Frontiers in Conservation Science, 42. \| Abstract	August 2021	Human-wildlife interactions are embedded within socio-ecological systems (SES), in which animal behavior and human decision-making reciprocally interact. While a growing body of research addresses specific social and ecological elements of human-wildlife interactions, including conflicts, integrating these approaches is essential for identifying practical and effective solutions. Carnivore predation on livestock can threaten human livelihoods, weaken relationships among stakeholders, and precipitate carnivore declines. As carnivores have received greater protection in recent decades, researchers and managers have sought non-lethal tools to reduce predation and promote coexistence between livestock producers and carnivores. For these tools to be successful, they must effectively deter carnivores, and they must also be adopted by producers. Relatively few studies examine the practical and context-specific effectiveness of non-lethal tools, and even fewer simultaneously consider their social acceptability among producers. To address this gap, we suggest that a tool's ecological effectiveness and social acceptability be analyzed concurrently to determine its <i>social effectiveness</i>. We thus paired an experimental study of a carnivore predation deterrent called Foxlights<sup>®</sup> with qualitative interviews of livestock producers in Northern California. We placed camera traps in sheep pastures to measure the response of coyotes (<i>Canis latrans</i>) to experimentally deployed Foxlights and interviewed livestock producers before and after the experiment. Our experiment revealed weak evidence for reducing coyote activity with Foxlights, but interviews revealed that the potential adoption of tools had as much to do with their social acceptability and implementation feasibility as with evidence-based measurements of tool effectiveness. Interviewees viewed Foxlights as potentially effective components of husbandry systems, despite the data suggesting otherwise, demonstrating that scientific reductionism may lag behind producer practices of systems-thinking and that isolated demonstrations of a tool's ecological effectiveness do not drive tool adoption. Future empirical tests of non-lethal tools should better consider producers' perspectives and acknowledge that data-based tests of ecological effectiveness alone have a limited place in producer decision-making. Iteratively working with producers can build trust in scientific outputs through the research process itself.

Veggerby K, Scheuerell MD, Sanderson B, Kiffney P. Stable isotopes reveal intertidal fish and crabs use bivalve farms as foraging habitat in Puget Sound, Washington. \| Abstract	January 2024	Bivalves such as oysters and clams have been farmed in the Puget Sound region of the Salish Sea for thousands of years. Indigenous peoples have traditionally used systems called clam gardens to modify stretches of shoreline habitat to create ideal conditions for edible bivalves. More recently, oysters, clams, and other bivalves have been grown by both First Nation and non-First Nation farmers using a variety of gear types in intertidal zones across Puget Sound and the coast of Washington. These gear types create complex vertical structure and attachment points for aquatic epiphytes and invertebrates which increases habitat structural complexity, but may alter eelgrass cover in areas where bivalve farms and eelgrass meadows overlap. Eelgrass meadows are highly productive and ecologically foundational nearshore habitats that provide valuable ecosystem services including sediment deposition and stabilization, and the provision of nursery, refuge, and foraging habitat throughout much of the Puget Sound. Eelgrass meadows overlap with bivalve farming activities across many intertidal areas of Washington State. Many nearshore species of fish and crab inhabit both bivalve farm and eelgrass habitats, but how they are using the farm habitat and the importance of bivalve farm habitat for foraging and predator refuge relative to unfarmed eelgrass meadows is unclear. We used stable isotope mixing models to estimate, for several species of nearshore fish and crab in two areas of North Puget Sound, Washington, the percent diet originating from eelgrass meadows, pelagic planktonic sources, and oyster farm habitats. Our results indicate that several species of nearshore fish derive a significant proportion of their diets from farm areas, while others derive most of their diets from eelgrass habitat or planktonic sources. The results indicate that foraging habitat uses are species specific, and that modifying habitat will likely change both species composition and species usage of an area. Having an adequate amount of habitat diversity is needed to support the community of fishes and invertebrates that inhabit these intertidal areas.

Academic Press, Waltham, Massachusetts USA. 447 pages. \| Abstract	January 2015	Studies of sea otters in captivity began in 1932, producing important insights for conservation. Soviet (initiated in 1932) and United States (1951) studies provided information on captive otter husbandry, setting the stage for eventual large-scale translocations as tools for population restoration. Early studies also informed effective housing of animals in zoos and aquaria, with sea otters first publicly displayed in 1954. Surveys credited displayed otters in convincing the public of conservation values. After early studies, initial scientific data for captive sea otters in aquaria came from work initiated in 1956, and from dedicated research facilities beginning in 1968. Significant achievements have been made in studies of behavior, physiology, reproduction, and high-priority management issues. Larger-scale projects involving translocation and oil spill response provided extensive insights into stress reactions, water quality issues in captivity, and effects of oil spills.

Academic Press, Waltham, Massachusetts USA. 447 pages. \| Abstract	January 2015	In the late 1860s, declining US sea otter populations elicited concern because of prior excessive harvests. Congress mandated protection of Alaskan sea otters in 1868, but hunting continued unrestrained. The Fur Seal Treaty of 1911 (abrogated in 1941) protected sea otters in international waters, but was not applicable to most sea otter habitats and failed to terminate all legal sea otter harvests. Between 1941 and 1972 only the State of California was consistently engaged in sea otter conservation, based on a 1913 state law. Trends in cultural values toward protection of species based on imperiled status rather than economics led to the Marine Mammal Protection Act (1972), giving sea otters unambiguous protection in all US territorial waters. Sea otter habitat protection by the US government began in the 1890s. State marine protected areas potentially support sea otter conservation, particularly when paired with adjacent federal protected entities in or near sea otter habitat.

Journal of Fish Biology 89:1720-1739. doi:10.1111/jfb.13078 \| Abstract	September 2016	Increased freshwater growth of juvenile steelhead Oncorhynchus mykiss improved survival to smolt and adult stages, thus prompting an examination of factors affecting growth during critical periods that influenced survival through subsequent life stages. For three tributaries with contrasting thermal regimes, a bioenergetics model was used to evaluate how feeding rate and energy density of prey influenced seasonal growth and stage-specific survival of juvenile O. mykiss. Sensitivity analysis examined target levels for feeding rate and energy density of prey during the growing season that improved survival to the smolt and adult stages in each tributary. Simulated daily growth was greatest during warmer months (1 July to 30 September), whereas substantial body mass was lost during cooler months (1 December to 31 March). Incremental increases in annual feeding rate or energy density of prey during summer broadened the temperature range at which faster growth occurred and increased the growth of the average juvenile to match those that survived to smolt and adult stages. Survival to later life stages could be improved by increasing feeding rate or energy density of the diet during summer months, when warmer water temperatures accommodated increased growth potential. Higher growth during the summer period in each tributary could improve resiliency during subsequent colder periods that lead to metabolic stress and weight loss. As growth and corresponding survival rates in fresh water are altered by shifting abiotic regimes, it will be increasingly important for fisheries managers to better understand the mechanisms affecting growth limitations in rearing habitats and what measures might maintain or improve growth conditions and survival.

Thompson BK, SJ Converse and JD Olden. 2021. Mechanistic invasive species management models and their application in conservation. Conservation Science and Practice 3:e533. \| Abstract	September 2021	Management strategies to address the challenges associated with invasive species are critical for effective conservation. An increasing variety of mathematical models offer insight into invasive populations, and can help managers identify cost effective prevention, control, and eradication actions. Despite this, as model complexity grows, so does the inaccessibility of these tools to conservation practitioners making decisions about management. Here, we seek to narrow the science-practice gap by reviewing invasive species management models (ISMMs). We define ISMMs as mechanistic models used to explore invasive species management strategies, and include reaction-advection-diffusion models, integrodifference equations, gravity models, particle transport models, non-spatial and spatial discrete-time population growth models, cellular automata, and individual-based models. For each approach, we describe the model framework and its implementation, discuss strengths and weaknesses, and give examples of conservation applications. We conclude by discussing how ISMMs can be used in concert with adaptive management to address scientific uncertainties impeding action and with multiple objective decision processes to evaluate tradeoffs among management objectives. We undertook this review to support more effective decision-making involving invasive species by providing conservation practitioners with the information they need to identify tools most useful for their applications.

Global change biology 27.16 (2021): 3718-3731. \| Abstract	August 2021	Human activity and land use change impact every landscape on Earth, driving declines in many animal species while benefiting others. Species ecological and life history traits may predict success in human-dominated landscapes such that only species with “winning” combinations of traits will persist in disturbed environments. However, this link between species traits and successful coexistence with humans remains obscured by the complexity of anthropogenic disturbances and variability among study systems. We compiled detection data for 24 mammal species from 61 populations across North America to quantify the effects of (1) the direct presence of people and (2) the human footprint (landscape modification) on mammal occurrence and activity levels. Thirty-three percent of mammal species exhibited a net negative response (i.e., reduced occurrence or activity) to increasing human presence and/or footprint across populations, whereas 58% of species were positively associated with increasing disturbance. However, apparent benefits of human presence and footprint tended to decrease or disappear at higher disturbance levels, indicative of thresholds in mammal species’ capacity to tolerate disturbance or exploit human-dominated landscapes. Species ecological and life history traits were strong predictors of their responses to human footprint, with increasing footprint favoring smaller, less carnivorous, faster-reproducing species. The positive and negative effects of human presence were distributed more randomly with respect to species trait values, with apparent winners and losers across a range of body sizes and dietary guilds. Differential responses by some species to human presence and human footprint highlight the importance of considering these two forms of human disturbance separately when estimating anthropogenic impacts on wildlife. Our approach provides insights into the complex mechanisms through which human activities shape mammal communities globally, revealing the drivers of the loss of larger predators in human-modified landscapes.

Predation by Northern Pikeminnow and tiger muskellunge on juvenile salmonids in a high–head reservoir: implications for anadromous fish reintroductions. Transactions of the American Fisheries Society 145:521-536. \| Abstract	April 2016	The suitability of reservoir habitat for rearing anadromous salmonids and interactions with resident fish affect the feasibility of reintroductions above high–head dams. We evaluated the predation risk to anadromous salmonids considered for reintroduction in Merwin Reservoir on the North Fork Lewis River in Washington State for two use scenarios: year–round rearing and smolt migration. We characterized the role of the primary predators, Northern Pikeminnow Ptychocheilus oregonensis and tiger muskellunge Esox, lucius x E. masquinongy using stable isotopes and stomach content analysis, quantified seasonal per–capita predation using bioenergetics modeling, evaluated the size and age structures of the populations, and combined these inputs to estimate predation rates of size–structured population units. Northern Pikeminnow of fork length (FL) ≥ 300 mm were highly cannibalistic with modest seasonal per–capita ¬predation on salmonids, but were disproportionately much less abundant than smaller, less piscivorous conspecifics. The annual predation on Kokanee Oncorhynchus nerka (in biomass) by a size–structured u¬nit of 1,000 Northern Pikeminnow of FL ≥ 300 mm was analogous to 16,000–40,000 age–0 spring Chinook Salmon rearing year–round, or 400–1,000 age–1 smolts migrating April–June. The per–capita consumption of salmonids by Northern Pikeminnow of FL ≥ 200 mm was relatively low, due in large part to spatial segregation during the summer and the skewed size distribution of the predator population. Tiger muskellunge fed heavily on Northern Pikeminnow, other non–salmonids, and minimally on salmonids. Predation by tiger muskellunge, in addition to cannibalism, likely contributed to low recruitment of larger (more piscivorous) Northern Pikeminnow, with the effect being decreased predation risk to salmonids. This study highlights the importance of evaluating trophic interactions within reservoirs slated for reintroduction, as they can be functional migration corridors and may offer profitable juvenile–rearing habitats despite hosting abundant predator populations.

Journal of Applied Ecology 58:371-381. https://doi.org/10.1111/1365-2664.13772 \| Abstract	February 2021	1) Recent success in the conservation of many marine mammals has resulted in new management challenges due to increasing conflict with fisheries. Increasing predation by pinnipeds on threatened salmon is of particular concern. Seemingly, pinniped conservation is now in conflict with the recovery of threatened salmon, creating a dilemma for managers. <br><br>2) We use the Lower Columbia River as a case study for examining the relationship between seasonal California sea lion (<i>Zalophus californianus</i>) abundance and survival of threatened salmon. To quantify mortality associated with increasing sea lion abundance, we examined the effect of seasonal sea lion abundance on adult Chinook salmon<i> </i>(<i>Oncorhynchus tshawytscha</i>)<i> </i>survival during migrations through the Lower Columbia River. We integrated data on survival with data on population-specific migration timing, allowing quantification of the relationship between sea lion abundance and survival in 18 populations of spring-summer Chinook salmon listed as Threatened or Endangered under the U.S. Endangered Species Act.<br><br>3) Of the 18 populations examined, earlier migrating populations experienced lower survival in association with increased exposure to higher sea lion abundance. We estimated that in years with high sea lion abundance, the nine earliest-migrating populations experienced an additional 21.1% (16.3, 26.1) mortality compared to years with baseline sea lion abundance, while the nine latest migrating populations experienced an additional 10.1% (7.5, 13.0). <br><br>4)<i> Synthesis and Application.</i> Integrating datasets on seasonal survival and migration timing made it possible for us to estimate population-specific mortality associated with increased sea lion abundance in the Lower Columbia River. This information could not be produced from any one data set, highlighting the utility of data integration approaches. The mortality experienced by early migrating Chinook salmon suggests the potential for demographic and evolutionary consequences. Management actions such as hazing, relocating, or removing individuals that are frequent predators on salmon have been proposed. Identifying the management actions that will allow for socially and legally acceptable tradeoffs between multiple conservation and other social values will be facilitated by development of explicit multi-species management frameworks. Continued monitoring will help to reduce the substantial uncertainty about the effect of pinnipeds on salmon and the predicted outcomes of alternative management actions.

Ecosphere 14:e4366. \| Abstract	January 2023	Differences in the life history pathways of juvenile animals are often associated with differences in demographic rates in later life stages. For migratory animals, different life-history pathways often result in animals from the same population occupying distinct habitats subjected to different environmental drivers. Understanding how demographic rates differ among animals expressing different life history pathways may reveal fitness tradeoffs that drive the expression of alternative life history pathways and enable better prediction of population dynamics in a changing environment. To understand how demographic outcomes and their relationships with environmental variables differ among animals with different life history pathways, we analyzed a long-term mark-recapture dataset for Chinook salmon (<i>Oncorhynchus tshawytscha</i>) from the Wenatchee River, Washington, USA. Distinct life history pathways represented in this population include either remaining in the natal stream until emigrating to the ocean as a one-year-old (<i>natal-reach rearing</i>) or emigrating from the natal stream and rearing in downstream habitats for several months before completing the emigration to the ocean as a one-year-old (<i>downstream rearing</i>). We found that downstream-rearing fish emigrated to the ocean 19 days earlier on average and returned as adults from the ocean at higher rates. We detected a positive correlation between rate of return from the ocean by downstream-rearing fish and coastal upwelling in their spring of outmigration, whereas for natal-reach-rearing fish we detected a positive correlation with sea surface temperature during their first marine summer. Different responses to environmental variability should lead to asynchrony in adult abundance among juvenile life history pathways. A higher proportion of downstream-rearing fish returned at younger ages compared to natal-reach-rearing fish, which contributed to more variability in age at reproduction and greater mixing across generations. Our results provide an example of how diversity in juvenile life history pathways is associated with heterogeneity in demographic rates during subsequent life stages. This demographic heterogeneity can in turn affect variance in the aggregate population abundance and population response to environmental change. Our findings underscore the importance of considering life history diversity in demographic analyses and lay the foundation for the development of population models that account for different life history pathways.

Ecology and Evolution 13:e11087. \| Abstract	May 2023	Individual variation in life-history traits can have important implications for the ability of populations to respond to environmental variability and change. In migratory animals, flexibility in the timing of life-history events, such as juvenile emigration from natal areas, can influence the effects of population density and environmental conditions on population dynamics. We evaluated the functional relationships between population density and environmental covariates and the abundance of juveniles expressing different life-history pathways in a migratory fish, Chinook salmon (<i>Oncorhynchus tshawytscha</i>), in a river basin in Washington State, USA. We found that the abundance of younger emigrants from natal streams was best described by an accelerating or near-linear function of spawners, whereas the abundance of older emigrants was best described by a decelerating function of spawners. This supports the hypothesis that emigration timing varies in response to density in natal areas, with younger-emigrating life-history pathways comprising a larger proportion of emigrants when densities of conspecifics are high. We also observed positive relationships between winter stream discharge and abundance of younger emigrants, supporting the hypothesis that habitat conditions can also influence the expression of different life-history pathways. Our results suggest that early emigration, and a resultant increase in the use of downstream rearing habitats, may increase if winter precipitation increases in the future as is projected due to climate warming. Characterizing relationships between life-history expression and environmental conditions is a necessary first step in understanding the dynamics of species with diverse life-history strategies. As environmental conditions change – due to climate change, management, or other factors – resultant life-history changes are likely to have important demographic implications that will be challenging to predict if life-history diversity is not accounted for in population models.

Ecology and Evolution 14: e4585. \| Abstract	June 2023	Monitoring species to better understand their status, ecology, and management needs is a major expense for agencies tasked with biodiversity conservation. Community science data have the potential to improve monitoring for minimal cost, given appropriate analytical frameworks are established. We describe a framework for integrating data from the eBird community science platform with agency-collected monitoring data using a multi-state occupancy model. Our novel occupancy model accounts for the structural differences in eBird data and agency-collected monitoring data and allows for estimation of both occupancy and breeding probabilities. The framework was applied to Common Loons (Gavia immer) in Washington State. Common Loons are state listed in Washington as Sensitive and identified as a species of greatest conservation need, and little is known about their breeding distribution beyond the locations of known nesting pairs. Based on our model, we predicted that only 6.5% (95% Bayesian credible interval, BCI = 1.6%, 50.9%) of the 2324 sites in our sampling frame were occupied by Common Loons, though Common Loons were predicted to be breeding at 95% (95% BCI = 71.2%, 99.9%) of the lakes they occupied. We identified only 1 abiotic covariate – elevation – that was a useful predictor of occupancy or reproduction probabilities in Common Loons; improvements in the predictive power of our model might be achieved with information on difficult-to-monitor biotic covariates, such as fish community metrics. We found that state agency biologists were 16 times more likely to detect breeding Common Loons during a visit than were eBird users (94.2%, 95% BCI = 77.9%, 98.9% for agency biologists vs. 8.2%, 95% BCI = 6.3%, 10.4% for eBird users). However, the amount of effort expended by eBird users meant that they confirmed Common Loons at 94 sites while agency biologists confirmed them at just 24 sites. Importantly, though, certain information – namely, evidence of reproduction – was only contributed by agency biologists. Our results provide a better understanding of the distribution of Common Loons in Washington, while further demonstrating that community science data can be a valuable complement to agency-collected data, if appropriate frameworks are developed to integrate these data sources.

Marine and Coastal Fisheries: Dynamics, Management, and Ecosystem Science 14:e10205 https://doi.org/10.1002/mcf2.10205 \| Abstract \| Download	May 2022	In Pacific salmon, downward trends in size and abundance have been reported for species and stocks for over 40 years, but the patterns are inconsistent among regions and species. Interpretation of these trends is complicated by the many possible contributing factors, including short time series, data comprising a mix of stocks, and varying gear types. Here, we present data on the mass of individual Chinook salmon, <i>Oncorhynchus tshawytscha</i>, caught in the winter from 1946 to 2019 in central Puget Sound, Washington by participants in what may be the longest running salmon derby in North America, the Tengu Derby. In this annual recreational fishing competition, established by Japanese-Americans immediately after release from internment camps at the end of World War II, participants follow strict gear, area, and methods regulations, and catch almost exclusively salmon originating from and remaining in Puget Sound. Records revealed an overall decline in fish mass over the decades with a high degree of variability throughout the time series. Specifically, resident Chinook salmon exhibited several shifts, including an increase in size from a high in the 1950s to a low around 1980, followed by an increase to another high around 1990, and then a decline over the most recent 30 years. These salmon, displaying a form of differential migration by remaining in Puget Sound rather than migrating to the ocean coast, showed dissimilar trajectories compared with size trends of Puget Sound Chinook salmon as a whole reported previously. These distinct patterns in size for Chinook salmon from common origins associated with different migration patterns exemplify yet another important factor to be considered in the analysis and interpretation of such trends.

Biological Conservation, 289, p.110340. doi:https://doi.org/10.1016/j.biocon.2023.110340. ‌ \| Abstract	January 2024	Recolonizing species exhibit unique population dynamics, namely dispersal to and colonization of new areas, that have important implications for their management. One challenge is how to simultaneously model demographic and movement processes so that recolonizing species can be accurately projected over both time and space. Integrated population models (IPMs) have proven useful for making inference about population dynamics by integrating multiple data streams related to population states and demographic rates. However, traditional IPMs are not capable of representing complex dispersal and colonization processes, and the data requirements for building spatially explicit IPMs to do so are often prohibitive. Contrastingly, individual-based models (IBMs) have been developed to describe dispersal and colonization processes but do not traditionally integrate an estimation component, which is a major strength of IPMs. We introduce a framework for spatially explicit projection modeling that answers the challenge of how to project an expanding population using IPM-based parameter estimation while harnessing the individual-based movement modeling made possible by an IBM. Our model has two main components: [1] a Bayesian IPM-driven age- and state-structured population model that governs the population state process and estimation of demographic rates, and [2] an IBM-driven spatial model describing the dispersal of individuals and colonization of new territories. We applied this model to estimate current and project future dynamics of gray wolves (<i>Canis lupus</i>) in Washington State, USA. We used data from 74 telemetered wolves and yearly pup and pack size counts to parameterize the model, and then projected statewide dynamics over the next 50 years. Mean population growth was 1.29 (95% CRI 1.26-1.33) during initial recolonization from 2009 - 2020 and decreased to 1.03 (95% Prediction Interval 1.00-1.05) in the projection period (2021-2070). Our results suggest that gray wolves have a very high (>99%) probability of colonizing the last of Washington State’s three specified recovery regions by 2030, depending on alternative assumptions about how dispersing wolves select new territories. The spatially explicit modelling framework developed here can be used to project the dynamics of any species for which spatial spread is an important driver of population dynamics.

"Hunting mode and habitat selection mediate the success of human hunters." in review at Movement Ecology. \| Abstract	December 2024	As a globally widespread apex predator, humans have unprecedented lethal and non-lethal effects on prey populations and ecosystems. Yet compared to non-human predators, little is known about the drivers and consequences of human hunting behavior.<b> </b>Here, we characterized the hunting modes, habitat selection, and harvest success of 483 rifle hunters in California using high-resolution GPS data. We used Hidden Markov Models to characterize fine-scale behavior, and k-means clustering to group hunters by hunting mode, on the basis of their time spent in each behavioral state. Hunters exhibited three distinct and successful hunting modes (“coursing”, “stalking”, and “sit-and-wait”), with stalking as the most successful strategy. Across hunting modes, there was variation in patterns of selection for roads, topography, and habitat cover, with important differences in habitat use of successful and unsuccessful hunters across modes. Our study indicates that hunters can successfully employ a diversity of harvest strategies, and that hunting success is mediated by the interacting effects of hunting mode and landscape features. Such results highlight the breadth of human hunting modes, even within a single hunting technique, and lend insight into the varied ways that humans exert predation pressure on wildlife.

Canadian Journal of Fisheries and Aquatic Science 78:1611-1627 https://doi.org/10.1139/cjfas-2021-0047 \| Abstract \| Download \| Publisher Website	April 2021	The location and timing of spawning plays a critical role in pelagic fish survival during early life stages and can affect subsequent recruitment. Spawning patterns of Pacific herring (<i>Clupea pallasii</i>) were examined in Prince William Sound (1973–2019) where the population collapsed in 1993 and has failed to recover. Abrupt shifts in spawn distribution preceded the rapid increase in population size in the 1980s and later its collapse by one and two years, respectively. As the population declined, spawning contracted away from historically productive regions towards southeastern areas of the Sound, and the proportion of occupied spawning areas declined from 65% to <9%. Spatial differences in spawn timing variation were also apparent, as the median spawn date shifted earlier by 26 days in eastern and 15 days in western areas of Prince William Sound between 1980 and 2006, and then shifted later by 25 (eastern) and 19 (western) days over a 7-year period. Effects of contracted spawning areas and timing shifts on first-year survival and recruitment are uncertain and require future investigation.

Distribution, abundance, and habitat associations of a large bivalve (Panopea generosa) in a eutrophic, fjord estuary. Journal of Shellfish Research 34: 137-145. \| Abstract	March 2015	Marine bivalves are important ecosystem constituents and frequently support valuable fisheries. In many nearshore areas, human disturbance including declining habitat and water quality, can affect the distribution and abundance of bivalve populations, and complicate ecosystem and fishery management assessments. Infaunal bivalves, in particular, are frequently cryptic and difficult to detect; thus assessing potential impacts to their populations requires suitable, scalable methods for estimating abundance and distribution. Here population size of a common benthic bivalve (geoduck clams, Panopea generosa) is estimated with a Bayesian habitat-based model fit to SCUBA and tethered camera data in Hood Canal, a fjord basin in Washington State, USA. Densities declined over two orders of magnitude along a north-south gradient concomitant with patterns of deep-water dissolved oxygen and intensity and duration of seasonal hypoxia. Across the basin, geoducks were most abundant in loose, unconsolidated, sand substrate. The present study demonstrates the utility of using SCUBA, tethered video, and habitat models to estimate the abundance and distribution of a large infaunal bivalve at a regional (385 km2) scale.

Effects of geoduck (Panopea generosa) aquaculture on resident and transient macrofauna communities of Puget Sound, Washington, USA. Journal of Shellfish Research 34: 189-202. \| Abstract	March 2015	In Washington State, commercial culture of geoduck clams (Panopea generosa) involves large-scale out-planting of juveniles to intertidal habitats and installation of PVC tubes and netting to exclude predators and increase early survival. Here we examine whether structures associated with this nascent aquaculture method affect patterns of use by resident and transient macrofauna. We summarize results of regular surveys of aquaculture operations and reference beaches in 2009-2011 at three sites during three phases of culture: 1) pre-gear [- geoducks, -structure]; 2) gear-present [+geoducks, +structures]; and 3) post-gear [+geoducks, -structures]. Resident macroinvertebrates (infauna and epifauna) were sampled monthly (in most cases) using coring methods at low tide during all three phases. Differences in community composition between culture plots and reference areas were examined with Permutational Analysis of Variance (PerMANOVA) and homogeneity of Multivariate Dispersion (HMD) tests. SCUBA and shoreline transect surveys were used to examine habitat use by transient fish and macroinvertebrates. Analysis of Similarity (ANOSIM) and complementary non-metric Multidimensional Scaling (NMDS) were used to compare differences between species functional groups and habitat type at different aquaculture phases. Results suggest that resident and transient macrofauna respond differently to structures associated with geoduck aquaculture. No consistent differences in the community of resident macrofauna were observed at culture plots or reference areas at the three sites during any year. Conversely, total abundance of transient fish and macroinvertebrates were more than two times higher at culture plots than reference areas when aquaculture structures were in place. Community composition differed (ANOSIM) between culture and reference plots during the gear-present phase, but did not persist to the next farming stage (post-gear). Habitat complexity associated with shellfish aquaculture may attract some structure-associated transient species observed infrequently on reference beaches, while displacing other species that typically occur in areas lacking epibenthic structure. This study provides the first look at the effects of multiple phases of geoduck farming on macrofauna and has important implications for management of a rapidly expanding sector of the aquaculture industry.

Environmental Science and Policy. 2023. \| Abstract	December 2023	For more than a century, wildlife conservation in the United States has been built on the notion that nonhuman animal populations are resources to be regulated by law and managed efficiently, according to the best available science and in the public trust. This approach, known as the North American Model of Wildlife Management, has proved effective by many metrics, but it has come under increasing criticism for excluding diverse viewpoints that have the potential to advance both conservation and environmental justice goals. How might the greater inclusion of Indigenous worldviews and Indigenous Studies concepts, such as radical relationality and kincentricity , improve traditional wildlife management? In this paper, we review three case studies of tribal wildlife stewardship programs in California—the Maidu Summit Consortium’s beaver restoration project, the Karuk Tribe’s elk management program, and the Yurok Tribe’s condor recovery effort—that illuminate generative connections among ecological restoration, Indigenous cultural practices, community wellbeing, and environmental justice. Radical relationality and kincentricity offer enormous potential for informing stewardship and recovery efforts that produce more just outcomes for both people and wildlife.

"Including Rural America in academic conservation science." Accepted, Frontiers in Conservation Science. \| Abstract	August 2023	Conservation has made great strides by embracing DEIJ efforts, but these efforts can improve the science and practice of conservation further by attending to rural populations. Here we offer strategies for strengthening inclusion of rural Americans in conservation science and practice. We suggest three pathways toward this goal: (i) emphasize knowledge co - production and partnerships that resonate with rural lifestyles and values; (ii) recruit and train rural students in conservation science degree programs; and (iii) reshape academic advancement criteria to promote rural engagement. We suggest that investments in academic - rural collaboration hold potential to build knowledge, trust, inclusion, and justice in the United States.

Ecology and evolution, 11(22), 15683-15694. \| Abstract	November 2021	With rapid global change, the frequency and severity of extreme disturbance events are increasing worldwide. The ability of animal populations to survive these stochastic events depends on how individual animals respond to their altered environments, yet our understanding of the immediate and short-term behavioral responses of animals to acute disturbances remains poor. We focused on animal behavioral responses to the environmental disturbance created by megafire. Specifically, we explored the effects of the 2018 Mendocino Complex Fire in northern California, USA, on the behavior and body condition of black-tailed deer (<i>Odocoileus hemionus columbianus</i>). We predicted that deer would be displaced by the disturbance or experience high mortality post-fire if they stayed in the burn area. We used data from GPS collars on 18 individual deer to quantify patterns of home range use, movement, and habitat selection before and after the fire. We assessed changes in body condition using images from a camera trap grid. The fire burned through half of the study area, facilitating a comparison between deer in burned and unburned areas. Despite a dramatic reduction in vegetation in burned areas, deer showed high site fidelity to pre-fire home ranges, returning within hours of the fire. However, mean home range size doubled after the fire and corresponded to increased daily activity in a severely resource-depleted environment. Within their home ranges, deer also selected strongly for patches of surviving vegetation and woodland habitat, as these areas provided forage and cover in an otherwise desolate landscape. Deer body condition significantly decreased after the fire, likely as a result of a reduction in forage within their home ranges, but all collared deer survived for the duration of the study. Understanding the ways in which large mammals respond to disturbances such as wildfire is increasingly important as the extent and severity of such events increases across the world. While many animals are adapted to disturbance regimes, species that exhibit high site fidelity or otherwise fixed behavioral strategies may struggle to cope with increased climate instability and associated extreme disturbance events.

When the Wild Things Are: Defining Mammalian Diel Activity and Plasticity. Science Advances, 11,eado3843(2025). DOI:10.1126/sciadv.ado3843 \| Abstract	March 2025	Circadian rhythms are a mechanism by which species adapt to environmental variability and fundamental to understanding species behavior. However, we lack data and a standardized framework to accurately assess and compare temporal activity for species during rapid ecological change. Through a global network representing 38 countries, we leveraged 8.9 million mammalian observations to create a library of 14,857 standardized diel activity estimates for 445 species. We found less than half the species’ estimates were in agreement with diel classifications from the reference literature and that species commonly used more than one diel classification. Species diel activity was highly plastic when exposed to anthropogenic change. Furthermore, body size and distributional extent were strongly associated with whether a species is diurnal or nocturnal. Our findings provide essential knowledge of species behavior in an era of rapid global change and suggest the need for a new, quantitative framework that defines diel activity logically and consistently while capturing species plasticity.

In addition, the degree to which winter dynamics in aquatic systems respond to large-scale climate versus ecosystem-level factors is unclear but important for understanding and managing potential changes. We used a unique winter data set from the Upper Mississippi River System to explore spatial and temporal patterns in phytoplankton biomass (chlorophyll <i>a</i>, CHL) and associated environmental covariates across 25 years and ∼1,500 river km. To assess the role of regional climate versus site-specific drivers of winter CHL, we evaluated whether there were coherent long-term CHL dynamics from north to south and across lotic-lentic areas. We then estimated the degree to which these patterns were associated with climate variability (i.e., the Multivariate El Nino-Southern Oscillation Index), winter severity (freezing degree days), river discharge, or site-specific environmental variables (ice depth, snow depth, and nutrient concentrations). We found that winter CHL was typically highest in ice-free reaches and backwater lakes, occasionally exceeding summer values. We did not find highly synchronous CHL dynamics across the basin, but instead show that temporal trends were independent among river reaches and lotic-lentic areas of the river. Moreover, after accounting for these spatial dynamics, we found that CHL was most responsive to winter air temperature, being consistently higher in years with warmer winters across the basin. These results indicate that although productivity dynamics are highly dynamic within large river ecosystems, changes in the duration and severity of winter may uniformly increase wintertime productivity.

PLoS ONE 18(7): e0289246. https://doi.org/10.1371/journal.pone.0289246 \| Abstract	July 2023	The decline in salmon and steelhead populations in the Columbia River Basin has been well documented, as have the decades-long, $9 billion restoration spending efforts by federal and state agencies. These efforts are mainly tied to Endangered Species Act (ESA) mandates for recovery of wild, naturally-spawning threatened or endangered fish species. The impact of these efforts remains poorly understood; many observers, including the federal courts, have long been concerned by the lack of evidence of recovery. Most studies evaluating restoration efforts have examined individual projects for specific species, reaches, or life stages, which limits the ability to make broad inferences at the basin level. There is a need to ask: is there evidence of an overall increase in wild fish abundance associated with the totality of these recovery efforts? To that end, the current study estimates fixed-effects panel regression models of adult returns of four species. Results indicate that restoration spending combined with hatchery production are associated with substantial increases in returning adult fish. Evidence of benefits to wild fish alone, however, require indirect approaches given the commingling of restoration spending with spending on hatchery releases, the impacts of spending on hatchery fish survival, and the density dependence effects of hatchery releases. To accomplish this, the model’s predicted adult returns (both hatchery and wild fish) attributed to both spending and hatchery releases are compared to independent estimates of returning hatchery fish based on hatchery survival estimates (smolt-to-adult ratios). The comparison finds the model-predicted levels of adult returns due to spending and hatchery releases do not exceed the survival-rate based estimates for hatcheries alone, so that we are unable to reject the hypothesis of no benefits to wild fish from the restoration spending.

DOI: 10.1080/00028487.2015.1079554 \| Abstract	October 2015	The Threespine Stickleback Gasterosteus aculeatus is widely distributed across northern hemisphere ecosystems, has ecological influence as an abundant planktivore, and is commonly used as a model organism, but the species lacks a comprehensive model to describe bioenergetic performance in response to varying environmental or ecological conditions. This study parameterized a bioenergetics model for the Threespine Stickleback using laboratory measurements to determine mass- and temperature-dependent functions for maximum consumption and routine respiration costs. Maximum consumption experiments were conducted across a range of temperatures from 7.5C to 23.0C and a range of fish weights from 0.5 to 4.5 g. Respiration experiments were conducted across a range of temperatures from 8C to 28C. Model sensitivity was consistent with other comparable models in that the mass-dependent parameters for maximum consumption were the most sensitive. Growth estimates based on the Threespine Stickleback bioenergetics model suggested that 22C is the optimal temperature for growth when food is not limiting. The bioenergetics model performed well when used to predict independent, paired measures of consumption and growth observed from a separate wild population of Threespine Sticklebacks. Predicted values for consumption and growth (expressed as percent body weight per day) only deviated from observed values by 2.0%. Our model should provide insight into the physiological performance of this species across a range of environmental conditions and be useful for quantifying the trophic impact of this species in food webs containing other ecologically or economically important species.

Clark & Levy (American Naturalist, 131, 1988, 271–290) described an antipredation window for smaller planktivorous fish during crepuscular periods when light permits feeding on zooplankton, but limits visual detection by piscivores. Yet, how the window is influenced by the interaction between light regime, turbidity and cloud cover over a broad latitudinal gradient remains unexplored. 2. We evaluated how latitudinal and seasonal shifts in diel light regimes alter the foragingrisk environment for visually feeding planktivores and piscivores across a natural range of turbidities and cloud covers. Pairing a model of aquatic visual feeding with a model of sun and moon illuminance, we estimated foraging rates of an idealized planktivore and piscivore over depth and time across factorial combinations of latitude (0–70°), turbidity (01–5 NTU) and cloud cover (clear to overcast skies) during the summer solstice and autumnal equinox. We evaluated the foraging-risk environment based on changes in the magnitude, duration and peak timing of the antipredation window. 3. The model scenarios generated up to 10-fold shifts in magnitude, 24-fold shifts in duration and 55-h shifts in timing of the peak antipredation window. The size of the window increased with latitude. This pattern was strongest during the solstice. In clear water at low turbidity (01–05 NTU), peaks in the magnitude and duration of the window formed at 57–60° latitude, before falling to near zero as surface waters became saturated with light under a midnight sun and clear skies at latitudes near 70°. Overcast dampened the midnight sun enough to allow larger windows to form in clear water at high latitudes. Conversely, at turbidities ≥2 NTU, greater reductions in the visual range of piscivores than planktivores created a window for long periods at high latitudes. Latitudinal dependencies were essentially lost during the equinox, indicating a progressive compression of the window from early summer into autumn. 4. Model results show that diel-seasonal foraging and predation risk in freshwater pelagic ecosystems changes considerably with latitude, turbidity and cloud cover. These changes alter the structure of pelagic predator–prey interactions, and in turn, the broader role of pelagic consumers in habitat coupling in lakes.

Journal of Animal Ecology, 91(1), 46-60. \| Abstract	January 2022	Spatiotemporal variation in predation risk arises from interactions between landscape heterogeneity, predator densities and predator hunting mode, generating landscapes of fear for prey species that can have important effects on prey behaviour and ecosystem dynamics. As widespread apex predators, humans present a significant source of risk for hunted animal populations. Spatiotemporal patterns of risk from hunters can overlap or contrast with patterns of risk from other predators. Human infrastructure can also reshape spatial patterns of risk by facilitating or impeding hunter or predator movement, or deterring predators that are themselves wary of humans. We examined how anthropogenic and natural landscape features interact with hunting modes of rifle hunters and mountain lions <i>Puma concolor</i> to generate spatiotemporal patterns of risk for their primary prey. We explored the implications of human-modified landscapes of fear for Columbian black-tailed deer <i>Odocoileus hemionus columbianus</i> in Mendocino County, California. We used historical harvest records, hunter GPS trackers and camera trap records of mountain lions to model patterns of risk for deer. We then used camera traps to examine deer spatial and temporal activity patterns in response to this variation in risk. Hunters and mountain lions exhibited distinct, contrasting patterns of spatiotemporal activity. Risk from rifle hunters, who rely on long lines of sight, was highest in open grasslands and near roads and was confined to the daytime. Risk from mountain lions, an ambush predator, was highest in dense shrubland habitat, farther from developed areas, and during the night and crepuscular periods. Areas of human settlement provided a refuge from both hunters and mountain lions. We found no evidence that deer avoided risk in space at the scale of our observations, but deer adjusted their temporal activity patterns to reduce the risk of encounters with humans and mountain lions in areas of higher risk. Our study demonstrates that interactions between human infrastructure, habitat cover and predator hunting mode can result in distinct spatial patterns of predation risk from hunters and other predators that may lead to trade-offs for prey species. However, distinct diel activity patterns of predators may create vacant hunting domains that reduce costly trade-offs for prey. Our study highlights the importance of temporal partitioning as a mechanism of predation risk avoidance.

Journal of Animal Ecology. 85:1307-1317. doi: 10.1111/1365-2656.12565 \| Abstract	August 2016	Summary 1. Understanding the limits of consumption is important for determining trophic influences on ecosystems and predator adaptations to inconsistent prey availability. Fishes have been observed to consume beyond what is sustainable (i.e. digested on a daily basis), but this phenomenon of hyperphagia (or binge-feeding) is largely overlooked. We expect hyperphagia to be a short-term (1-day) event that is facilitated by gut volume providing capacity to store consumed food during periods of high prey availability to be later digested. 2. We define how temperature, body size, and food availability influence the degree of binge-feeding by comparing field observations with laboratory experiments of bull trout (Salvelinus confluentus), a large freshwater piscivore that experiences highly variable prey pulses. We also simulated bull trout consumption and growth during smolt outmigrations under two scenarios: 1) daily consumption being dependent upon bioenergetically-sustainable rates, and 2) daily consumption being dependent upon available gut volume (i.e. consumption is equal to gut volume when empty, and otherwise “topping off” based on sustainable digestion rates). 3. One-day consumption by lab-held bull trout during the first day of feeding experiments after fasting exceeded bioenergetically-sustainable rates by > 80-fold at low temperatures (3° C) and by ~1.3-fold at 20° C. The degree of binge-feeding by bull trout in the field was slightly reduced but largely in agreement with lab estimates, especially when prey availability was extremely high (during a sockeye salmon [Oncorhynchus nerka] smolt outmigration and at a counting fence where smolts are funnelled into high densities). Consumption by bull trout at other settings were lower and more variable, but still regularly hyperphagic. 4. Simulations demonstrated the ability to binge-feed increased cumulative consumption (16-32%) and cumulative growth (19-110%) relative to only feeding at bioenergetically sustainable rates during the ~1 month smolt outmigration period. 5. Our results indicate the ability for predators to maximize short-term consumption when prey are available can be extreme and is limited primarily by gut volume, then mediated by temperature; thus predator-prey relationships may be more dependent upon prey availability than traditional bioenergetics models suggest. Binge-feeding has important implications for energy budgets of consumers as well as acute predation impacts on prey.

The results demonstrate nearly exclusive and intense feeding by S. confluentus on outmigrant smolts, and supports recent telemetry observations of high disappearance rates of O. nerka smolts leaving large natural lake systems prior to entering high-order unregulated river systems.

Abstract Black abalone, Haliotis cracherodii, populations along the NE Pacific ocean have declined due to the rickettsial disease withering syndrome (WS). Natural recovery on San Nicolas Island (SNI) off Southern California suggested the development of resistance in island populations. Experimental challenges in one treatment demonstrated that progeny of disease-selected black abalone from SNI survived better than did those from naïve black abalone from Carmel Point (CP) in mainland coastal central California. Unexpectedly, the presence of a newly observed bacteriophage infecting the WS rickettsia (WS-RLO) had strong effects on the survival of infected abalone. Specifically, presence of phage-infected RLO (RLOv) reduced the host response to infection, RLO infection loads, and associated mortality. These data suggest that the black abalone: WS44 RLO relationship is evolving through dual host mechanisms of resistance to RLO infection in the digestive gland via tolerance to infection in the primary target tissue (the post-esophagus) coupled with reduced pathogenicity of the WS-RLO by phage infection, which effectively reduces the infection load in the primary target tissue by half. Sea surface temperature patterns off southern California, associated with a recent hiatus in global-scale ocean warming, do not appear to be a sufficient explanation for survival patterns in SNI black abalone. These data highlight the potential for natural recovery of abalone populations over time and that further understanding of mechanisms governing host-parasite relationships will better enable us to manage declining populations.

Fisheries Research 242: 106014 https://doi.org/10.1016/j.fishres.2021.106014 \| Abstract \| Download \| Publisher Website	October 2021	Fishery managers often rely on forecasts of future population abundance to set allowable harvest quotas or exploitation rates. While there has been substantial research devoted to identifying environmental factors that can predict recruitment for individual populations, such correlations often degrade over time, thereby limiting their utility for management. Conversely, examining multiple populations at once to detect shared, spatially structured patterns can offer insights into their recruitment dynamics that are advantageous for forecasting. Here, we develop a population dynamics model for coho salmon (<i>Oncorhynchus kisutch</i>) stocks in Washington State that leverages spatial and temporal autocorrelation in marine survival to improve one-year-ahead forecasts of adult returns. Executed in a Bayesian hierarchical integrated modelling framework, our spatiotemporal approach incorporates multiple data types and shares information among stocks to estimate key biological parameters that are informative for forecasting. Retrospective evaluation of one-year-ahead forecast skill indicated that the spatiotemporal integrated population model outperformed existing forecasts of Washington state coho salmon returns by ~25-38% on average. Our results add to a growing body of work demonstrating the utility of spatiotemporal and integrated approaches for modelling population dynamics, and the framework developed here has broad applications to the assessment and management of coho salmon in Washington State and throughout their range.

Diseases of Aquatic Organisms 108: 261-270. doi: 10.3354/dao02713. \| Abstract	April 2014	Withering Syndrome, WS, is a fatal disease of abalone caused by a Rickettsia-like organism (WS-RLO). The causative agent, “Candidatus Xenohaliotis californiensis”, occurs along the eastern Pacific margin of North America in California, USA and Baja California, Mexico. However, as infected abalones have been transported to Chile, China (People’s Rep. of), Taiwan, Iceland, Ireland, Israel, Spain, Thailand, and most recently Japan, and possibly other countries, the geographical range of the etiological agent is suspected to be broad where California red abalones, Haliotis rufescens, are cultured or in areas where native species have been exposed to this species. Susceptibility varies among species with up to 99% losses of black abalone, H. cracherodii, in lab and field studies in the USA to no losses among H. diversicolor supertexta in Thailand. Some populations that have suffered catastrophic losses to WS have developed an increased resistance to the disease. In addition, a newly identified phage hyperparasite of the WS-RLO may reduce pathogenicity and dampen losses from the WS-RLO. Diagnosis of WS requires the identification of infection with the pathogen (WS-RLO via in situ hybridization or via histology coupled with PCR and sequence analysis) accompanied by morphological changes that characterize this disease (e.g. pedal and digestive gland atrophy, and digestive gland metaplasia). A real-time PCR (qPCR) assay has been developed and may be useful in quantifying amounts of pathogen DNA. Confirmation of infection by the WS-RLO cannot be done by PCR analysis alone as this method only detects pathogen DNA, but can be used as a proxy for infection in areas where the agent is established. Control measures include avoidance, culling infected animals and, as per federal regulations, oral or bath treatment with oxytetracycline. Avoidance is best accomplished by the establishment of a health history and multiple health examinations prior to movement of animals. Although histology or in situ hybridization are required to confirm infection, qPCR is able to detect small amounts of pathogen DNA and is advised to be included as part of health examinations.

"Movement behavior in a dominant ungulate underlies successful adjustment to a rapidly changing landscape following megafire." Movement Ecology. \| Abstract	December 2024	Background:<br>Movement plays a key role in allowing animal species to adapt to sudden environmental shifts. Anthropogenic climate and land use change have accelerated the frequency of some of these extreme disturbances, including megafire. These megafires dramatically alter ecosystems and challenge the capacity of several species to adjust to a rapidly changing landscape. Ungulates and their movement behaviors play a central role in the ecosystem functions of fire-prone ecosystems around the world. Previous work has shown behavioral plasticity is an important mechanism underlying whether large ungulates are able to adjust to recent changes in their environments effectively. Ungulates may respond to the immediate effects of megafire by adjusting their movement and behavior, but how these responses persist or change over time following disturbance is poorly understood.<br>Methods:<br>We examined how an ecologically dominant ungulate with strong site fidelity, Columbian black-tailed deer (<i>Odocoileus hemionus columbianus</i>), adjusted its movement and behavior in response to an altered landscape following a megafire. To do so, we collected GPS data from 21 individual female deer over the course of a year and used resource selection functions (RSFs) and hidden Markov movement models (HMMs) to assess changes in behavior and habitat selection.<br>Results:<br>We found compelling evidence of adaptive capacity across individual deer in response to megafire. Deer avoided exposed and severely burned areas that lack forage and could be riskier for predation immediately following megafire, but they later altered these behaviors to select for areas that burned at higher severities, potentially to take advantage of enhanced forage.<br>Conclusions:<br>These results suggest that despite their high site fidelity, deer can navigate altered landscapes to track rapid shifts in predation risk and resource availability. This successful adjustment of movement and behavior following extreme disturbance could help facilitate resilience at broader ecological scales.

Ecological Applications \| Abstract	December 2022	Increasingly frequent megafires are dramatically altering landscapes and critical habitats around the world. Across the western United States, megafires have become an almost annual occurrence, but the implication of these fires for the conservation of native wildlife remains relatively unknown. Woodland savannas are among the world’s most biodiverse ecosystems and provide important food and structural resources to a variety of wildlife, but they are threatened by megafires. Despite this, the great majority of fire impact studies have only been conducted in coniferous forests. Understanding the resistance and resilience of wildlife assemblages following these extreme perturbations can help inform future management interventions that limit biodiversity loss due to megafire. We assessed the resistance of a woodland savanna mammal community to the short-term impacts of megafire using camera trap data collected before, during, and after the fire. Specifically, we utilized a 5-year camera trap data set (2016–2020) from the Hopland Research and Extension Center to examine the impacts of the 2018 Mendocino Complex Fire, California’s largest recorded wildfire at the time, on the distributions of eight observed mammal species. We used a multispecies occupancy model to quantify the effects of megafire on species’ space use, to assess the impact on species size and diet groups, and to create robust estimates of fire’s impacts on species diversity across space and time. Megafire had a negative effect on the detection of certain mammal species, but overall, most species showed high resistance to the disturbance and returned to detection and site use levels comparable to unburned sites by the end of the study period. Following megafire, species richness was higher in burned areas that retained higher canopy cover relative to unburned and burned sites with low canopy cover. Fire management that prevents large-scale canopy loss is critical to providing refugia for vulnerable species immediately following fire in oak woodlands, and likely other mixed-forest landscapes.
Calhoun, Kendall L., et al. "Spatial overlap of wildfire and biodiversity in California highlights gap in non‐conifer fire research and management." Diversity and Distributions 28.3 (2022): 529-541. \| Abstract	March 2022	Aim <br>Global change has spurred the escalation of megafires in California over the last 20 years throughout a variety of ecosystems. Here, we examine the spatial distribution of California wildfires and megafires from the last two decades (2000–2020) in relation to ecosystem types and biodiversity metrics. We offer insights into the prevalence of fire across vegetation types and its potential implications for biodiversity, and for fire and land management. These results challenge the prevailing discourse that wildfire in California is chiefly an issue of forest management.<br> <br>Location <br>California, United States of America.<br> <br>Methods <br>We calculated burned area across vegetation types from 2000 to 2020 by integrating fire perimeter and land cover data and compared this to a content analysis of coverage of wildfires by media and scientific research across California. We then compared the distribution of fire perimeters across biodiversity metrics (richness and endemism) for five terrestrial taxonomic groups (birds, reptiles, plants, mammals and amphibians) and against the distribution of the wildland-urban interface (WUI).<br> <br>Results <br>Total burned area from 2000 to 2020 was highest in shrubland ecosystems (38%), followed by conifer (36%), hardwood (17%) and grasslands (9%). In aggregate, ecosystems other than conifer make up the majority (64%) of the area burned in wildfires over the last 20 years. Fires most likely to impact endemic species, overlap areas of high species richness or burn within the WUI occurred predominantly in non-conifer ecosystems.<br> <br>Main Conclusions <br>Fires outside of forests have burned biodiverse areas critical to endemic species, but recent research and management in fire ecology continues to focus disproportionately on forests.<br> Non-conifer forested areas in California represent an important gap in fire research and management. As fire regimes shift dramatically in the state, other ecosystem types must be part of the wider conversation on fire management and policies to better protect people and biodiversity.

Mammalian Biology (2022): 1-12. \| Abstract	February 2022	Non-invasive genetic sampling can facilitate the identification of individual animals across a landscape, with applications to management and conservation. Fecal material is a readily available source of DNA, and various methods exist for collecting fecal samples for DNA preservation. In particular, swab methods offer considerable promise, but their utility in real-world field contexts remains relatively untested. We systematically compared multiple genetic fecal sampling methods across all stages of data collection and analysis, including sampling in the field, DNA extraction in the lab, and identification of individuals using microsatellite genotyping. We collected 112 fecal samples from black-tailed deer (<i>Odocoileus hemionus columbianus</i>) in the field in Mendocino County, California, across a range of sample conditions of unknown age. We systematically compared the efficiency, ease, and genotyping success of three methods for field collection and storage of ungulate fecal samples: whole pellets in ethanol, whole dry pellets in paper envelopes, and cotton swabs in buffer. Storage method, sample condition, and their interaction predicted genotyping success in the top binomial GLMMs. We found that swabbing pellets resulted in the greatest percentage of individually identifiable genotypes (81%, compared to 60% for dry samples and 56% for ethanol), despite lower DNA concentrations. While swabbing pellets requires a greater time investment in the field, the samples are easier and safer to store and transport, and subsequent labwork is more efficient as compared to whole-pellet collection methods. We, therefore, recommend the swab method for most contexts. We provide additional recommendations and field protocols based on subsequent collection of 2284 swab samples for a larger monitoring study of the deer population, given that this large number of samples spanned a range of sample conditions and time spent in storage.

"The socioecology of fear: a critical geographical consideration of human-wolf-livestock conflict." The Canadian Geographer (intended). \| Abstract	December 2023	Animal fear can be an important driver of ecological community structure: predators affect prey not only through predation, but by inducing changes in behavior and distribution—a phenomenon evocatively called the “ecology of fear.” The return of wolves to the western United States is a notable instance of such dynamics, yet plays out in a complex <i>socio</i>-ecological system where efforts to mitigate impacts on livestock rely on manipulating wolves’ fear of people. Examining Washington state’s efforts to affect wolf behavior to reduce livestock predation, we argue that this approach to coexistence with wolves is predicated on relations of fear: people, livestock, and wolves can arguably share landscapes with minimal conflict, as long as wolves are adequately afraid. We introduce the “socioecology of fear” as an interdisciplinary framework for examining the interwoven social and ecological processes of human-wildlife conflict management. Beyond frequently-voiced ideas about wolves’ “innate” fear, we examine how fear is (re)produced through human-wolf interactions and deeply shaped by human social processes. We contribute to the Critical Physical Geography project by integrating critical social analysis with ecological theory, conducted through collaborative interdisciplinary dialogue. Such integrative practice is essential for understanding the complex challenges of managing wildlife in the Anthropocene.

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.

Neobiota 70: 107-122. \| Abstract	December 2021	Early detection and rapid response (EDRR) are essential to identifying and decisively responding to the introduction or spread of an invasive species, thus avoiding population establishment and improving the probability of achieving eradication. However, detection can be challenging at the onset of a species invasion as low population densities can reduce detection probability and conceal the true extent of the situation until the species is well established. This is doubly challenging if the invading species displays cryptic behavior or is nocturnal, thus further limiting opportunities for its discovery. Survey methods that maximize a searcher’s ability to detect an incipient population are therefore critical for successful EDRR. Brown treesnakes (<i>Boiga irregularis</i>) on Guåhan are a classic cautionary example of the dangers of not detecting an invasion early on, and the risk of their introduction to other islands within the Marianas, Hawai’i and beyond remains. Nocturnal visual surveys are known to detect brown treesnakes of all sizes and are the primary detection tool used by the Brown Treesnake Rapid Response Team, but detection probability remains low in complex forest habitats. As such, we investigated the use of two potential enhancements to nocturnal visual surveys – a live mouse lure and spray scent attractant – that may create hotspots of increased detection probability during surveys. We found that, while brown treesnake detection probabilities were low for all surveys, visual surveys conducted on transects with live mouse lures resulted in detection probabilities that were 1.3 times higher than on transects without live mouse lures. Conversely, the spray scent attractant did not increase the probability of detecting brown treesnakes compared to transects without scent, and in fact had detection probabilities that were 0.66 times lower, though the reasons for this phenomenon are unclear. Unlike scent attractants, live mouse lures likely provide both visual and olfactory cues that attract brown treesnakes to transects and thus provide more opportunities to detect and capture them. These enhancements were trialed on Guåhan, where prey populations are depressed. It remains unclear whether live mouse lures will be as effective for EDRR applications in prey-rich settings.

"Climate change as a global amplifier of human-wildlife conflict." Nature Climate Change. In review \| Abstract	December 2023	Climate change and human-wildlife conflict are both pressing challenges for biodiversity conservation and human wellbeing in the Anthropocene. Climate change is a critical yet underappreciated amplifier of human-wildlife conflict, as it exacerbates resource scarcity, alters human and animal behaviors and distributions, and increases human-wildlife encounters. We synthesize evidence of climate-driven conflicts occurring among 10 taxonomic orders, on six continents, and in all five oceans. Such conflicts disrupt both subsistence livelihoods and industrial economies, and may accelerate the rate at which human-wildlife conflict drives wildlife declines. We introduce a framework describing distinct environmental, ecological, and sociopolitical pathways through which climate variability and change percolate through complex social-ecological systems to influence patterns and outcomes of human-wildlife interactions. Identifying these pathways allows for developing mitigation strategies and proactive policies to limit the impacts of human-wildlife conflict on biodiversity conservation and human wellbeing in a changing climate.

VanBlaricom, G.R. 2016. Overlapping catastrophes in the intertidal ecosystems of San Nicolas Island. Annual Meeting, Marine Rocky Intertidal Network. San Diego, California USA. Oral presentation by VanBlaricom	February 2016	Poorly understood diseases have influenced populations of three different high-profile coastal marine invertebrate species at San Nicolas Island, California in 2015 and 2016, and an unprecedented coincident generalized physical disturbance has negatively influenced populations of all three species. The confluence of such events is a challenge to simple top-down trophic models in coastal marine ecosystems, complicating the management and conservation of such systems.

Scheuerell, M.D. 2022. Estimating Trends in the Abundance of Threatened Bull Trout across the Pacific Northwest. American Fisheries Society Annual Meeting, Spokane, WA, August 21-25, 2022.	August 2022	Effective conservation of at-risk species requires an understanding of trends in abundance over time, but in many cases the data necessary to estimate population trajectories are often quite noisy and incomplete. I used a hierarchical state-space model to estimate trends over time for 242 populations located in 62 core areas spread across the Pacific Northwest; approximately 60% of the core areas showed a decreasing trend over time, but only 5% of the core areas had significant declines.

May 2022	We found that riverine NO3- concentration, yield, δ15N and δ18O patterns were best defined by two river groupings associated with the two regional mountain ranges (Cascade vs. Olympic<br>mountains), and that hydrologic and climate variables best explained variation in NO3- concentration and yield. These results highlight that while regional-scale climate controls N delivery, finer-scale features at the watershed level play a distinct role in driving N sources.

September 2020	We simulated snake movement to better understand the way lure-attraction and camera trap density can influence abundance estimates of brown treesnakes. We found that with the highest lure-attraction and lowest number of cameras, density estimates were highly biased and imprecise under all models.
Amburgey SM, AA Yackel Adams, B Gardner, B Lardner, AJ Knox, and SJ Converse. 2021. An evaluation of tools for increasing brown treesnake detection probabilities to enhance early detection and rapid response. Marianas Terrestrial Conservation Conference. Virtual.	June 2021	Early detection and rapid response (EDRR) to the introduction or spread of an invasive species is key to the prevention of establishment or success of eradication. We evaluate two methods (the use of mouse lures and spray scent) for increasing the detection probability of invasive brown treesnakes during visual surveys as a potential tool for EDRR. We found that use of mouse lures can increase detection of brown treesnakes while spray scent actually lowers detection probability.

Brown Treesnake Technical Working Group Annual Meeting, Guam; 14-18 November.	November 2022	Monitoring invasive species can be both critical for management and quite expensive. We describe a process for optimizing monitoring and apply it to brown treesnakes in Guam.
