Wisconsin angler preferences survey	October 2014	Changes in fish communities result in different opportunities for anglers. Our objective was to design and implement a survey to ascertain angler preferences related to the attributes of largemouth bass, bluegill, and walleye fisheries on order to determine where anglers might choose to fish based on trade-offs in fishing opportunities among these species. During November 2013, the survey was sent to 6,000 anglers and with the help of Dave Fulton (Minnesota Cooperative Fish and Wildlife Research Unit) we are analyzing the data using choice models.	Managing recreational fisheries in lake‐rich landscapes with diverse fish communities and anglers alike presents a social and biological challenge for managers. Understanding angler preferences is central to navigating these challenges and can aid in predicting shifts in angler behavior in response to management actions or changing fish populations. Species‐specific angler surveys do not incorporate tradeoffs inherent in multispecies fisheries, thus limiting their application to real‐world management issues. To better understand angler preferences in relation to realistic tradeoffs among different fishing opportunities, we conducted a survey of Wisconsin anglers in 2013–2014 that included questions requiring anglers to choose between fisheries providing different outcomes. We used stated‐preference modeling to quantify angler preferences associated with Bluegill <i>Lepomis macrochirus</i>, Largemouth Bass <i>Micropterus salmoides</i>, and Walleye <i>Sander vitreus</i> fisheries. Next, we conducted a latent class analysis using survey responses to classify anglers into subgroups. Finally, we assessed the sensitivity of angler choice to changes in fishing opportunities. Results of the stated‐preference models indicated that both residents and nonresidents largely prefer “quality” (i.e. moderate catch rate and size structure) over “action” or “trophy” Bluegill fisheries and that characteristics of Largemouth Bass fisheries have more value to nonresidents than to residents. Aspects of the Bluegill fishery were most important in choosing among hypothetical lakes for resident respondents. Five angler subgroups were identified that show the importance of Bluegill and Walleye but shed additional light on anglers’ commitment level and nonresidents’ preference for Largemouth Bass. In addition, simulations of changes in Walleye, Largemouth Bass, and Bluegill fisheries indicated that maintenance of quality Bluegill fisheries is important to ensuring continued angler participation, while the retention of high‐yield Walleye fisheries is likely paramount to a subgroup of anglers. Our results offer insight into angler preferences across the lake‐rich landscape of Wisconsin and demonstrate how angler behavior may shift in response to transitions in fishing opportunities.
Range-wide migratory connectivity for full-cycle conservation of the golden-winged warbler, climate sensitive songbird of the highest conservation concern	December 2016	Golden-winged warblers are a species of conservation concern, as they have experience dramatic population declines in the eastern portion of their breeding distribution, in spite of relatively high nest success. This study is designed to evaluate movements and spatial affiliations of golden-winged warblers outside of the breeding season.	Golden-winged warblers are a species of conservation concern, as they have experience dramatic population declines in the eastern portion of their breeding distribution, in spite of relatively high nest success. Considerable effort has been expended by management agencies to increase the abundance and quality of breeding habitat, with limited population response, suggesting that factors outside the breeding distribution may be influencing golden-winged warbler populations. We used light-level geolocators deployed across the breeding distribution of golden-winged warblers to evaluate migratory connectivity and migration. Our results indicate strong migratory connectivity, with golden-winged warblers from the eastern portion of their breeding distribution associated with wintering areas in northern South America, where deforestation rates are much higher than in Central America, where warblers from the western portion of their breeding distribution spend the winter. Our results suggest that conservation efforts on the wintering grounds are at least as important as maintaining breeding habitat.
Marshbird response to invasive cattail control using grazing, mowing, and herbicide application in the Prairie Pothole Region of Minnesta	December 2017	Invasive vegetation significantly alters wetland habitat and effects bird and other vertebrate communities. This project is designed to evaluate the response of bird communities to control of invasive vegetation.	Invasive vegetation significantly alters wetland habitat and effects bird and other vertebrate communities. In the Prairie Pothole Region, invasive cattails (Typha X glauca) form monocultures of dense mats, altering the vegetation in wetlands used by a variety of birds, including secretive marshbirds. Land managers in this region, including the U.S. Fish and Wildlife Service and the Minnesota Department of Natural Resources use fire and grazing to effect upland vegetation, but how this management affects wetland vegetation and wetland birds is not clear. This project is designed to evaluate the response of bird communities to control of invasive vegetation and provide information to more effectively manage Prairie Potnole Region wetlands.
Delineating sandhill crane populations in Minnesota	June 2017	Portions of both he Mid-Continent and Eastern Populations of sandhill cranes breed in Minnesota, but how birds from each population are distributed is not well documented. This project is designed to better understand sandhill crane distribution in Minnesota.	Portions of both he Mid-Continent and Eastern Populations of sandhill cranes breed in Minnesota, but how birds from each population are distributed and where these populations come into contact is not well documented. Management strategies for these two populations differ, and it is therefore necessary to know how they interact in space and time. We evaluated the current boundary between these populations and their movement ecology and local and broad (e.g., migration) spatial and temporal scales. Our results provide critical information relevant to managing these populations to the U.S. Fish and Wildlife Service, the Minnesota Department of Natural Resources, and other management agencies.
2014 Wild Turkey Hunter Study	December 2016	The goal of our study is to enhance our understanding of turkey hunter attitudes and perceptions of regulatory alternatives. Specific objectives of this study are to: 1) Critically evaluate Minnesota's spring turkey hunting season and determine if changes are appropriate; 2) Examine alternatives that provide more opportunity, improve hunter satisfaction, remain safe, and sustain the population at the goal level; 3) Use study result to implement regulatory harvest changes that achieve hunter and turkey population objectives.

Research Associate in Human dimensions	December 2013	Due to demand from the Minnesota Department of Natural Resources (DNR) to conduct studies focused on the human dimensions aspects of fisheries, wildlife, and ecological management issues a Human Dimensions Research Fellow position was created in the Department of Fisheries, Wildlife and Conservation Biology at the University of Minnesota. The position was funded jointly by the Minnesota Department of Natural resources and the Minnesota Cooperative fish & Wildlife Research Unit. This position has helped to ensure that data addressing a variety of fisheries wildlife management issues are collected in a consistent fashion across activities and issues and over multiple years. The position has also allowed human dimensions research to be collected more efficiently and more rapidly than would be the case using graduate student research efforts. In fiscal year 2010, the research fellow position was converted to a research associate position. The research associate will have primary responsibility for designing, implementing, analyzing, and reporting 3 studies using a variety of social science methods including focus groups, surveys and field experiments. These studies will include use of advanced methods and statistical analyses including Q methodology, choice models, and structural equation modeling. During this time period the research associate will have primary responsibility for designing, implementing, analyzing and reporting up to 3 studies each year focused on the human dimensions of fisheries, wildlife, or ecological management issues of interest to the Minnesota DNR. The research associate will conduct these studies in close cooperation and under the supervision of the Minnesota Cooperative Fish and Wildlife Research Unit Assistant Unit Leader, Dr. David Fulton.

Bovine TB management in deer n northwest Minnesota	October 2012	Longterm, we expect that the information generated from this project will be used to identify valid risk-based testing alternatives, surveillance systems, and implementation strategies that will support the USDA-Animal and Plant Health Inspection Service and States in eradication of BTB from livestock and wildlife. The primary obtive is to improve the effectiveness of bovine tuberculosis eradication programs developed and implemented by state agencies including the Minnesota DNR, by identifying the risk perceptions, beliefs, attitudes, social and personal norms, and behaviors among landowners/cattle producers and deer hunters relevant to BTB; understanding how risk perceptions, beliefs, attitudes, norms and behaviors affect willingness of cattle producers and deer hunters to support or implement BTB policy; and identifying the social networks existing among cattle producers and deer hunters that allow exchange of information about BTB. This objective will be achieved by increasing the knowledge and understanding of social and psychological factors influencing cattle producers’ and deer hunters’ support for BTB eradication programs.

Minnesota Waterfowl Hunters 2011/12	December 2012	Minnesota has generally been in the top 3 states for number of waterfowl hunters in the United States. In recent years we have expanded efforts to obtain quantitative information about opinions and motivations for this important clientele. Minnesota participated in the North American Duck Hunter Survey (Ringelman 1997) and Minnesota hunter responses were compared to those in other States (Lawrence and Ringelman 2001). More recently, reports documenting hunter activity and opinions following the 2000, 2002, 2005, and 2007 waterfowl hunting seasons were completed (Fulton et al. 2002, Schroeder et al. 2004, 2007a, 2008). A survey following the 2010 season is currently being analyzed. In addition, a series of surveys looking at hunter recruitment and retention were completed following the 2005 waterfowl hunting season (Schroeder et al. 2007b,c,d) and a study of former waterfowl hunters was completed following the 2009 season (Schroeder et al., 2011 draft). Information from these reports has been used to inform management decisions. We originally planned on completing the statewide survey at 3 year intervals, but have made exceptions. We conducted a survey in 2002 instead of 2003 to obtain current estimates of spinning-wing decoy use, and a limited survey was conducted following the 2007 waterfowl hunting season to evaluate changes in daily bag limits. We conducted a survey following the 2010 waterfowl season, but changes in waterfowl hunting regulations in 2011 necessitate the need for an additional hunter survey. Specifically, duck season opened 1 week earlier, shooting hours on opening day began at ½ hour before sunrise instead of 9 a.m., wood duck daily bag limit was increased from 2 to 3, and the hen mallard daily bag limit was increased from 1 to 2. In addition, 2010 was the first year Minnesota used zones for duck seasons. In 2011 we have the opportunity to add an additional zone. Thus, the survey will provide opinions on how hunters perceived the 2010 zones, and obtain recommendations for the 2011 zones. Objective: Identify hunter preferences/opinion on daily bag limits and zones relative to their satisfaction, success, and opinions/preferences on other waterfowl hunting and management issues. These results will be compared to results from previous Minnesota surveys and other hunter surveys. Determine how preferences/opinions vary based upon hunter characteristics. Basic Questionnaire Themes The questionnaire will be similar to the 2000, 2002, 2005, 2007, and 2010 questionnaires and many questions will be the same so we can compare hunter responses following different waterfowl seasons. In addition, questions on daily bag limits, duck zones and splits, Canada goose management, waterfowl hunting framework dates, and other current issues may be addressed. We will review questionnaires and results from other state waterfowl hunter surveys and coordinate with biologists in other states to assist in designing the Minnesota survey. In 2012, states can select a zone/split combination for the 2012-2015 period. This survey will also provide essential information for selecting the best option for Minnesota.	None
Minnesota Landowner Perceptions of Deer Management in SE Minnesota	June 2013	The Minnesota Department of Natural Resources (MDNR) has done extensive work with deer hunters in southeastern Minnesota. Since 2005, DNR has staffed biological deer check stations to assess age and sex ratios or harvested deer, surveyed hunters regarding attitudes and acceptance of different regulations, and ultimately changed regulations in 2010. Unlike previous surveys that have focused on a particular group (e.g., anglers waterfowl hunters, deer hunters), DNR research has not been conducted on private landowners. This is an important segment of the population as they control access and may or may not change their behavior based on their perceptions of deer populations and regulations. While southeastern Minnesota is a dynamic landscape with a mix of traditional agriculture, dairy/cattle, and recreational landowners, their opinions are poorly understood. Also, there is a perception that leasing for hunting is increasing and management options may be limited along with access restrictions. Objectives: 1) Conduct focus groups with landowners to determine the underlying issues and complications with private land deer management. 2) Use the focus groups to inform development of a self-administered mail back questionnaire to landowners. 3) Develop a dataset for analysis so that data can be presented at Legislative hearings, public meetings, and to wildlife staff. 4) These results will be compared with other survey results in the to finalize future harvest regulations.

Evaluation of Walk-in Access User Program	June 2014	The Walk-In Access (WIA) program provides public access to private land and pays landowners by the acre to allow hunting access. The program is currently in its second year of a three-year Walk-In pilot program. The program has grown to more than 15,000 acres giving hunters access to more than 150 sites across 21 counties. Feedback indicates that the Walk-In access is working for both hunters and landowners. The majority of WIA acres are enrolled for multiple years and are also enrolled in a federal or state conservation program designed to maintain cover on the acres. The U.S. Department of Agriculture (USDA) funded the first two years of the program and the Minnesota Legislature has approved additional funding for WIA. A $5 surcharge on non-resident hunting licenses has been directed to the program and resident hunters have the opportunity to donate $1, $3 or $5 to the program when purchasing a small game or deer license. Hunter support is key to the program. Using the land, respecting the land and identifying a method to fund the program for the long term will be essential to build the future of the program. Objectives: 1) Develop a survey instrument and self-administered mail back questionnaire to WIA users to determine basic attitudes and support for the WIA program. 2) Develop a dataset for analysis so that data can be presented at Legislative hearings, public meetings, and to wildlife staff. 3) These results will be compared with other surveys and programs to develop recommendations for future funding and management of the WIA program.

Assessing landowners'/producers' attitudes toward and motivations for participating in conservation programs beneficial to wildlife	July 2015	The behaviors of individual land-owners, many of whom actively farm their properties, have the potential to conserve water quality as well restore and conserve fisheries and wildlife habitat. In fact, the steering committee for the Eastern Tallgrass Prairie and Big Rivers LCC has identified a need to better understand the motivations of landowners for participating in programs that improve wildlife habitat and water quality in the region. This proposal addresses that need. The scope of this study is to: 1) evaluate if wildlife benefits are a driving factor for producer enrollment in USDA programs that address the resource concern of water quality in terms of sedimentation and nutrient loading; and 2) to identify and evaluate the motivating reasons that producers enter into sustainable agricultural systems. The outcomes of this study will provide insight into designing and developing programs, practices and messages that encourage broader participation in conservation programs and sustainable practices within the agricultural community.

Resource use of arctic peregrine falcons along the Colville River, Alaska	December 2015	The Colville River Special Area (CRSA) was designated in 1977 to protect nesting and foraging habitat of the then-endangered Arctic peregrine falcon. The objectives of this project are to (1) summarize and evaluate existing CRSA peregrine nesting data to assess nesting habitat use and related productivity, and (2) implement additional data collection efforts focused on assessing nesting area occupancy related to habitat and other factors associated with productivity. This information will help inform management of the CRSA.

Minnesota Climate Change Vulnerability Assessment	December 2012	The Minnesota Department of Natural Resources convened expert panels to conduct ecosystem-scale climate change vulnerability assessments for selected habitats using a systems mapping process. The mapping process identified key drivers of change, relationships among drivers, stressors and their relative strength of influence, including the assignment of vulnerability and confidence scores. The goal is to compile the data gathered from the expert panels to inform adaptation strategies relative to climate change scenarios into Minnesota’s State Wildlife Action Plan.	None
Understanding the imporance of weak-tie networks in complex	December 2011	In agriculture, ‘multifunctionality’ refers to production of a range of agricultural commodities and conservation of biodiversity and water quality. Multifunctional agriculture addresses a range of social and ecological challenges to sustainability. This project is conducted by an interdisciplinary team to evaluate multifunctional agriculture as a coupled human-environment system driven by ecosocial feedback, weak-tie social networks, and multiple biophysical benefits. Weak tie networks allow the shared perception of biophysical signals, communication, resource exchange, and collective action by individuals and groups to generate ecological benefits and increase the size and resource base of social networks. Work will occur in New York, Pennsylvania, and Wisconsin that differ in adoption of rotational grazing (RG). The project will examine individual and group behavior and development of social-network, assess the biophysical effects on terrestrial and aquatic systems at farm and landscape scales. Our portion of the project addresses stream channel characteristics and aquatic macroinvertebrate communities in relation to RG compared with continuously grazed pastures. The proposed research will help identify both opportunities and barriers affecting development of a sustainable bioeconomy based on multifunctional agriculture.	None
Scaleable indices of watershed health	June 2011	A watershed-based approach is increasingly recognized as the most comprehensive framework for understanding and managing natural resource systems, including streams and lakes. However, for this approach to be successful, a large amount information regarding the current state of watershed resources is necessary. Unfortunately, despite the large amount of existing geographic information system (GIS) information that could be utilized, this information is not readily available for managers in an easily accessible, broadly applicable, summarized form. The Watershed Assessment Tool (WAT) Project is designed to bridge this gap by acquiring background information on watershed concepts and developing a comprehensive series of GIS layers. This information will be organized in a 5-component framework of hydrology, geomorphology, biology, connectivity and water quality to facilitate quantification of healthy watershed function and interactions. We are developing a meta-analyses and syntheses to support the broad-scale, long-term quantification of watershed health in major Minnesota watersheds (8-digit HUC boundaries), the selection of a set of health indices, and the application of these health indices for all such watersheds in Minnesota. This work is specifically designed to support the development of the Minnesota Department of Natural Resources (MNDNR) watershed assessment tool.	None
Predicting large wood transport and effects on stream geomor...	June 2009	Large wood performs many important ecosystem functions in streams, including diversifying instream flow environments (e.g., plunge pools, and backwater habitat), creating overhead cover for fish, and providing a stable substrate for invertebrates and periphyton. Few instream studies of large wood dynamics have been completed in the Midwest, rather the majority of studies have been from mountainous areas with steeper gradients and narrower floodplains. We will use individual logs to investigate instream wood dynamics in streams flowing through second-growth forest to improve our understanding of instream wood processes in the Midwest. We will relate mobilization and retention of individual pieces to geomorphic conditions and piece characteristics. We hypothesize that shorter, smaller, and more buoyant pieces will be mobilized more readily than large dense pieces, and that channels that are steeper, wider, and more entrenched will retain less wood than narrow, shallow, nonentrenched channels. Information gained from this study will be broadly disseminated and used to improve riparian management policies, wood removal regulations, and stream restoration practices.	None
Predicting and mitigating vulnerability of trout streams	June 2013	Trout require streams with excellent water quality that are fed by groundwater, which keep streams cold in summer but ice-free in winter. The trout sport-fishing industry is vulnerable to global climate changes that can increase stream temperatures, alter the cold-adapted aquatic insects that form trout diets, and affect trout reproduction. Increasing air temperatures are predicted to increase the maximum water temperatures during summer, but also are very likely to dramatically change winter thermal conditions in trout streams. Our objectives are to: (1) investigate the role of stream bank vegetation and adjacent land use to minimize changes in stream temperatures in relation to climate change during summer; (2) determine winter diets and growth of trout populations; and (3) determine kinds, abundances, and timing of growth patterns of cold-adapted insects that are essential in winter diets of trout. We will work on 36 trout streams in the Driftless Area, using GIS coupled with habitat surveys for objective (1); seining and standard diet analysis techniques for objective (2); and rapid bioassessment protocols for objective (3). The project will identify and rank the streams most vulnerable to increases in summer high temperatures, and will identify cold-adapted insects that are most critical to trout diets and growth during winter. Trout fishing annually provides more than $150 million dollars in direct expenditures to local economies in Minnesota and $654 million through the Driftless Region (Trout Unlimited, 2008). With re-circulating dollars this represents more than one-billion dollars of economic stimulus to local economies. Our research will enable us to identify streams and food species that are most vulnerable to increasing temperatures, and translate scientific results into management strategies to protect and conserve this valuable industry.

Geographical Information Systems techniques to channel slope	September 2006	Our goal is to evaluate automated methods to estimate channel gradient, and to develop estimates of stream power and flood discharge and frequency for unregulated streams within Minnesota. Studies have demonstrated relationships between the gradient of stream channels and fish and macroinvertebrate assemblages. Twenty-one of 35 habitat features in Wyoming streams were related to channel gradient. Although field techniques to measure channel gradient are standardized, several techniques to estimate stream gradient using a GIS exist, but a standard technique has not been chosen. The objectives are to: determine a method for measuring channel gradient that provides similar estimates to field measurements with standard techniques, identify GIS method(s) that provide similar estimates to measurements made in the field, and develop estimates of flood discharges using regression equations based on our field and GIS methods.

Ecological and genetic characteristics of slimy sculpin in s...	June 2009	The Departments of Natural Resources in Iowa, Minnesota, and Wisconsin have implemented “reintroduction” programs for sculpin Cottus spp. in streams in the Driftless Area Ecoregion of each state. The goal of these projects is to increase the distribution of sculpin by re-establishing viable, self-sustaining populations in trout streams where native populations are presumed to have been present historically, but were extirpated and unable to recolonize (http://www.dnr.state.mn.us/areas/fisheries/lanesboro/management.html). This effort will potentially restore an ecologically important species to these coldwater streams and provide an additional prey component for wild trout populations. Sculpin were successfully reintroduced to a southwest Wisconsin stream in the 1970s. However, the reintroduction programs were instituted with limited information about the ecological suitability of the streams selected for reintroduction. This study will investigate genetic characteristics, survival, prey availability, diet of slimy sculpin, and habitat of donor and recipient streams. Our goal is to determine characteristics of streams most amenable to establishing reintroduced populations and examine ecological exchangeability of the sculpin.	None
Empowering water quality decisions: reducing uncertainty and	June 2009	Impaired waters and the Total Maximum Daily Load approach are central drivers to water quality management mandated by the Clean Water Act. Water quality and ecological integrity vary across a gradient of human disturbance, but assessing how ecological integrity is affected by human disturbance is complex and requires robust indicators of ecological health. Indicators are used to quantify stream ecosystem integrity; however, uncertainty and variability of those indicators are poorly understood. We will conduct research that will aid Minnesota regulatory agencies in reducing the uncertainty and variability of indicators of stream ecosystem integrity to allow managers to make decisions based on scientific knowledge and be more defensible than current decisions. We have three objectives: (1) quantify the uncertainty surrounding stream health indicators, (2) evaluate the variability of indicators of stream health at different spatial scales, and (3) deconstruct stream health indices to understand which index metrics contribute most to uncertainty and variability at different spatial scales. Our project will advance management of stream ecological resources by aiding accurate identification of impaired streams, using existing data to understand the history of stream ecosystem integrity, and increasing efficiency with which stream ecosystem integrity is assessed and monitored.

Development of an ecological assessment method for Minnesota...	June 2009	The Minnesota Pollution Control Agency has encouraged the Department of Natural Resources to identify and develop two lake health indicators that could be used to assess whether Minnesota lakes are impaired as part of the Minnesota Legislature’s Clean Water Legacy Initiative to facilitate the implementation of the Total Maximum Daily Load process mandated by the Clean Water Act. Our goal is to evaluate indictors of lake health should be used for assessing the ecological integrity of lakes in Minnesota, focusing on an indicator that will complement the fish index of biological integrity (fish IBI) that has developed. Our objectives are to: (1) review the existing indicators of lake health that have been used in temperate lakes, (2) use existing data within Minnesota to evaluate the applicability and robustness of existing measures of lake health, (3) prioritize approaches across the gradient of Minnesota lake types and identify data gaps, and (4) identify an approach to complement the fish IBI method, and recommend a general framework for its use in Minnesota.

Assessing the cumulative impacts to near-shore, in-water hab	June 2013	Human structures related to shoreline development, such as docks, boatlifts, and other structures, and disturbance from recreational activity may have a cumulative impact on aquatic ecosystems. Near-shore areas (less than 4 meters deep) often contain most of the vegetation and are generally the spawning area for fish. Few studies have addressed the effects of incremental changes on lake ecosystems despite ongoing concerns about the rate and extent of near-shore, in-water habitat alterations, and expansion of in-lake structures. The lack of scientific knowledge on the cumulative effects of human activities on aquatic habitat, water quality, and fish populations has hindered regulatory authorities and lake managers who need better information to guide landowners toward lower impact practices. To address this lack of information, we will assess the extent of near-shore vegetation and fish along a gradient of shoreline development and develop a framework to assess cumulative impacts on whole lake systems. We will use aerial photos and existing DNR data to measure whole lake disturbances of 114 lakes in the Northern Lakes and Forests Ecoregion. We will also conduct assessments of a subset of 30 lakes at the individual lot scale, to quantify impacts to vegetation and fish along a gradient of shoreline development and shoreline types. We will use our research develop a model to predict the cumulative impact of development on aquatic ecosystems, providing a tool to guide lake managers toward sustainable near-shore, in-water development.

Comparison of effects on stream habitat and fish nine years	June 2008	Riparian guidelines have been the most controversial of the seven components of Minnesota’s forest management guidelines. Research addressing the long-term effectiveness of riparian guidelines is critical to resolving riparian management conflicts, informing the ongoing revisions of the Minnesota Forest Resources Council’s (MFRC) riparian guidelines, and sustaining Minnesota’s forest resources. This project will (1) evaluate the long-term effectiveness of Minnesota’s riparian guidelines on eight northern Minnesota sites and at 12 previously established sites in the Pokegama Creek basin, (2) combine and synthesize data from the multiple study components through a “meta-analysis,” and (3) provide information to natural resource professionals about riparian zone management. Specifically, we: (1) evaluate the effects of riparian harvest on stream ecosystem functioning using measures of invertebrate biomass, in-stream leaf and wood decomposition rates, in-stream habitat, and food web analyses and (2) evaluate the effects of harvest treatments through time on both the terrestrial (birds, trees and herbaceous biomass) and aquatic habitat components as well as changes of terrestrial and aquatic communities (fish and invertebrate) in a meta-analysis.

Summarizing data and developing conservation practices for eagle nesting and concentration areas in the Midwest Region	September 2012	Bald and golden eagles have special legal status in the United States and the U.S. Fish and Wildlife Service has legal management authority. Bald eagles have rebounded to high population levels across the Midwestern U.S. following banning of some organochlorine pesticides, which inhibited reproduction. In contrast, golden eagles are relatively rare in the Midwestern U.S., and there is concern about golden eagle mortality associated with wind farms and other anthropogenic factors. We are working with U.S. Fish and Wildlife Service biologists and managers to compile information about bald and golden eagles in the Upper Midwest, and develop conservation strategies and identify research priorities.

Assessment of techniques for evaluating woodcock population response to best management practices applied at the demonstration area scale	December 2014	American woodcock are a species of conservation concern, having experienced long-term population declines over much of their breeding distribution in eastern North America. Prescriptions for increasing woodcock abundance focus on managing landscapes to provide breeding habitat, but there is little information that can be used to evaluate the success of those efforts. We are evaluating abundance, habitat use, and survival of American woodcock in relation to habitat management at the landscape (demonstration-area) scale in northwest Minnesota, with collaborative projects in Maine and New York. Results of this study will inform landscape-scale management for American woodcock and other species that use similar landscapes.

Bioregional monitoring for northern goshawks in the western Great Lakes	August 2009	Northern goshawks are a species of conservation concern, in part because of their purported association with mature forest cover types. However, these habitat associations are not well documented in the Upper Midwest, where most information on goshawk populations is derived from monitoring nests. We modified an existing protocol to estimate occupancy of northern goshawks in the western Great Lakes region, and conducted a field survey in 2008 following that protocol. Our results suggest that goshawks are widely distributed at relatively low densities across the western Great Lakes region, and use more mature forest stands for nesting.

Partners on this project include White Earth Nation natural resource staff and USDA-Aphis National Wildlife Research Center.	None
Attitudes toward RNAi methods for controlling invasive carp.	December 2025	RNA interference (RNAi) methods suggest promising means for controlling invasive carp species as well as zebra mussels and other aquatic invasive species but people’s attitudes towards such methods are unclear. Understanding attitudes toward RNAi are necessary for effective implementation. The objectives of this study are to: 1) investigate stakeholder awareness of RNAi, 2) identify concerns that they have about RNAi including what information they would to have to inform their decision making concerning whether to support the technology and how they would like to see the technology potentially used in controlling invasive carp or zebra mussels, 3) understand and describe their attitudes toward the perceived downstream risks of conducting RNAi control, and 4) identify the potential harms from this technology that stakeholders would want to make sure are rigorously studied. The outcomes of this project will inform future efforts to develop best practices for implementation of RNAi and provide key information needed to appropriately engage stakeholders to foster support.

Predicting the future of aquatic species in Minnesota	June 2026	Native aquatic species have had their ranges impacted by habitat degradation, climate change, invasive species, harvest, and other anthropogenic impacts. Each year the state of Minnesota spends millions of dollars on the conservation of aquatic native species. A booming economy relies on the state’s natural resources, with the outdoor recreation economy alone valued at $16.7 billion in 2022. The climate in Minnesota is predicted to continue changing substantially throughout this century, average annual temperature across the state has already increased nearly 3℉ since the late 1800s. To support the goal of Minnesota’s Department of Natural Resources, that ‘the benefits of all Minnesota’s natural resources are enjoyed by all Minnesotans’, it is important to anticipate and plan for likely future scenarios. By identifying native aquatic species most likely to be impacted by future climate change, and geographic areas with high levels of species change, management agencies can better focus their resources to protect and conserve these aquatic species in areas that will be most suited to them, for the benefit of Minnesota’s future. We will predict the ranges of native aquatic species in Minnesota using recently available high quality datasets and information on past and present ranges coupled with powerful statistical techniques.

Improving stock assessment of Walleye for Mille Lacs Lake.	June 2026	The Walleye fishery in Mille Lacs Lake has declined since the 1990s. The decline coincides with a variety of changesincluding: warming temperatures, increases in smallmouth bass, invasion of zebra mussels in 2005, invasion of spiny waterflea in 2009, changes to northern pike abundance, along with changes to the fishery (both in gear types and management).The fishery (along with northern pike, yellow perch, cisco and burbot) is co‐managed by tribes signatory to the 1837 Treatyand the state (through Minnesota Department of Natural Resources or MNDNR), based on legal agreements. The walleyefishery has consisted of a recreational and joint tribal fishery since 1998. The population of walleye is estimated annuallythrough a statistical catch at age (SCAA) model (previously a Virtual Population Analysis or VPA). The assessment modelswere reviewed in 2001 (VPA) by James R. Bence and Terrance J. Quinn II and again in 2014 (SCAA) by a blue ribbon panel(Paul Venturelli, James Bence, Travis Brenden, Nigel Lester, and Lars Rudstam). A variety of recommendations were madein those reviews for future data collection and future research to ensure the stock assessment model is as accurate aspossible, and this project will focus on improving some aspect of the stock assessment.

Minnesota Angler Study	December 2024	The goal of fisheries management is to provide for long term conservation of fisheries resources while at the same time optimizing the benefits that people obtain from the resources. For this reason, fisheries management involves the management of biological resources and of people. Understanding the concerns and desired experiences of anglers is an important aspect of maintaining satisfying fishing experiences for anglers and a successful fishery. In 1998, the Minnesota DNR conducted a statewide assessment of resident angler satisfaction with fishing experiences and attitudes and beliefs concerning fisheries management issues in the state (Minnesota Center for Survey Research 1998). In 2005 and 2011, 2018 follow-up statewide surveys were completed for the Minnesota DNR by the Minnesota Cooperative Fish & Wildlife Research Unit. This proposal is to complete a fifth cross-sectional statewide resident angler assessment that will allow exploration of changes, trends and new conditions. In the current research cycle, understanding anglers preferences concerning trade-offs in management foci and strategies under increasing conditions of budget constraints is again of particular interest to the Minnesota DNR. Purpose and Objectives: The purpose of this study is to provide a current update of angler attitudes and behaviors that can be compared with existing information over the past 24 years. The specific objectives of this study are to: 1. Determine anglers’ values, attitudes, norms and behaviors concerning fishing experiences, issues, and management. 2. Develop and refine a battery of items based on research studies in Minnesota and other states that will be used to track trends in angler’s preferences and attitudes on key issues and perceptions including satisfaction with the general fishing experience, satisfaction with the number and size of fish caught, perceptions of crowding, and other key indicators of the quality of fishing experiences. 3. Continue baseline data for tracking trends in angler perceptions and attitudes on various fisheries issues in Minnesota. 4. Determine differences between resident male and female anglers concerning values, attitudes, and behaviors. 5.

Habitat use of post-fledging forest-nesting songbirds in northern hardwood-coniferous forests in north-central MN	September 2010	Compared to use of nesting habitat, habitat use by forest-nesting songbirds following fledging is relatively poorly understood. Recent studies based on point counts and mist-netting, and monitoring movement of fledglings via radio-telemetry, suggest that for at least some species of forest-nesting songbirds, habitat use post-fledging can be quite different from breeding-habitat use. To date, information regarding habitat use following fledging for forest nesting birds is limited to a few studies from eastern (Virginia and West Virginia) and southern (Missouri) deciduous forests, and from only a few species of forest-nesting birds. No published information regarding post-fledging habitat use exists for northern hardwood-coniferous forest birds in the western Great Lakes region. Forest-management plans that incorporate considerations for forest-nesting birds generally do not consider habitat use following fledging. A more complete understanding of habitat use by forest-nesting birds in northern hardwood-coniferous forests would provide the basis for better incorporating considerations for forest-nesting birds in forest management in the western Great Lakes region. Specifically, our goals are to (1) determine what species of forest-nesting birds (both adults and fledglings) use a range of habitats from early successional to mature forest during the post-fledging period, and (2) document post-fledging movements and habitat use of selected forest-nesting species in northern hardwood-coniferous forests in northern Minnesota.

Factors affecting detection of American woodcock on singing-ground surveys	December 2011	American woodcock are a species of management concern, having experience population declines across much of their eastern North American breeding distribution. The Singing-ground Survey (SGS) is the primary mechanism by which American woodcock populations are monitored, although there remain questions about factors that influence counts on surveys. We are assessing factors that influence the reliability and precision of Singing-ground Surveys to estimate American woodcock population trends by 1) estimating detectability of woodcock using current sampling protocol, repeated (occupancy) sampling of a subsample of survey routes, assessing detectability based on video or telemetry to refine conditions under which woodcock are detectable, double observer assessment of detectability, and observer variability by repeating survey routes to assess detection probability through time, and (2) comparing woodcock density along SGS survey routes with randomly-located experimental routes in adjacent areas to directly assess whether counts on existing routes adequately represent the larger landscape. Results of this study can be used to refine survey protocol to better track woodcock abundance.

Effects of imperfect detectability on inferences from monitoring	July 2014	The value of bird monitoring has come under increasing scrutiny recently due to concerns about imperfect detectability. In particular, because the probability of detecting a bird in the area surveyed often is less than one, counts are only indices of abundance, rather than actual estimates of abundance. A variety of methods that attempt to adjust counts for imperfect detectability have been advanced; using these methods requires additional effort, however. A critical question is the extent to which that additional effort is rewarded by improved results. Clearly, estimates of abundance will be affected by adjustments for detectability; what is not known are the consequences on estimates of population trajectories. The goal of this study is to evaluate the influence of imperfect detectability on inferences about population changes. Specific objectives: - Determine the variation in detectability values that occur in avian surveys and understand factors that influence detectability. This objective will be addressed through literature reviews, discussions with bird surveyors, consultations with experts (e.g., Dr. Theodore Simons, North Carolina Cooperative Fish and Wildlife Research Unit), and possibly field trials. - Understand the influence that imperfect detectability can have on results of monitoring. This will be accomplished through investigations into the analytic methods applied to monitoring data, and simulation studies. - Determine the extent to which methods that adjust counts for imperfect detectability affect results from monitoring programs and inferences drawn from those results. This objective will be addressed by analyzing simulated and possibly actual field data with those methods. - Determine how detectability is affected by abundance and variety of birds and other features not well understood. This will require carefully designed field studies. The extent to which this objective will be necessary, and the exact features to be investigated, will depend in part on topics not addressed by Dr. Simons and his students.

Demographic response of golden-winged warbler to habitat and management across a climate change gradient in the core of the species range	April 2015	Golden-winged warblers are a specie of conservation concern, and have experienced dramatic population declines in the eastern portion of their breeding distribution. However, little is known about their population ecology in the western portion of their distribution, where the majority of the breeding population now occurs. We evaluated population ecology of golden-winged warblers in the core of their current breeding distribution to (1) compare golden-winged warbler reproductive success (nest productivity and juvenile survival) between two main breeding habitat types, (2) compare adult golden-winged warbler survival and habitat use during the nesting and post-fledging period between two main breeding habitat types, (3) use habitat characteristics to build a predictive model of golden-winged warbler reproductive success to provide management recommendations for maximizing high quality golden-winged warbler habitat, (4) replicate the study at 3 locations across a climate change gradient over 2 years to include critical spatial and temporal variation in analyses, maximizing the inference of results and applicability of management recommendations, and (5) combine demographic data with models of predicted climate change for the western Great Lakes region to predict climate-change effects on golden-winged warbler population viability.

The use of satellite telemetry to evalute migration chronology and breeding, migratory, and wintering distribution of Eastern Population sandhill cranes	June 2014	Eastern Population(EP) sandhill cranes were largely extirpated by the early 1990s, but have recently increased dramatically in abundance, in part due to prohibitions on harvest and management of protected areas where they breed, migrate, and winter. However, little specific information exists about migration ecology of this population, including information about specific stopover and wintering areas. The objectives pf this study are to (1) delineate the breeding and wintering distribution of EP sandhill cranes, (2) delineate migratory corridors for EP sandhill cranes and (3) determine migration chronology. Information from this study can be used to inform the management strategy for EP sandhill cranes.

American woodcock singing-ground surveys in the western Great Lakes region: Assessment of trends in woodcock counts, forest cover types along survey routes, and landscape cover type composition	June 2010	American woodcock are monitored via the Singing-ground Survey, which was established in the late 1960s. Since then, survey routes have largely been static, and it is no longer clear whether these routes adequately monitor woodcock abundance across the larger landscape. To assess whether survey routes currently represent the landscape they were initially designed to represent, we assessed patterns in annual counts of woodcock along existing survey routes in Minnesota and Wisconsin, assessed changes in time in land cover types along these routes, related temporal changes in woodcock counts to changes in land cover composition, and compared current cover type composition along routes to current landscape cover type composition. We also compared past cover type composition along survey routes to landscape cover composition. Our results suggest that existing routes largely reflect the cover types of the broader landscape, and also results in counts that track changes in cover types along routes.

Development of new eDNA tools to detect aquatic invasive plants in Upper Mississippi River Basin	December 2026	We will develop portable and rapid environmental DNA multispecies sequencing protocols (using the Nanopore MinION device) for detecting invasive aquatic plants through water samples. These tools will then be validated within the Upper Mississippi River Basin through comparison with ongoing, traditional aquatic plant field collections through the Upper Mississippi River Restoration Program and Minnesota’s Shallow Lakes Program. The results of this project provide guidance for new eDNA-based monitoring programs, including assessing the feasibility of these surveillance tools being used by future citizen science monitoring programs.

Investigating trends in turtle abundance from REEF data	December 2025	The Reef Environmental Education Foundation (REEF) collects citizen science surveys for a variety of marine species. REEF volunteers use the Roving Diver Technique (RDT), a visual survey method specifically designed for volunteer data. The only materials needed are an underwater slate and pencil, a good reference book, and access to the internet to submit the data online. The data is collated using a log scale for abundance where things are single (n=1), few (n=2-10), many (n=11-100), and abundant (n=101+). Recently Dr. Dan Greenberg developed a Bayesian model which can create area- and species- specific abundance estimates through time based on REEF RDT surveys. The abundance estimates have been used for species that are data-limited (e.g., Goliath Grouper in the southeastern US) and have been compared to scientific abundance estimates (e.g., coral reef fishes in Florida). This project seeks to build estimates of abundance for a variety of turtles species(Green turtles, Loggerhead turtles, and Hawksbill turtles) in multiple locations (Hawaii, Tropical Atlantic, and the Tropical Eastern Pacific). We hope to collaborate with scientists from NOAA to compare the abundance indices derived from REEF data to other indices and indicators of turtle populations.

Diversity and Access to Wildlife Opportunities	June 2025	Profound changes with how the American public values and relates to nature and wildlife are occurring. Participation rates in traditional activities associated with fish and wildlife have dropped dramatically putting into jeopardy the funding mechanisms for fish and wildlife conservation and potentially motivations to sustain these resources. In addition, there is an apparent broader disconnection of the American public to the outdoors and wildlife that could lead to substantive negative impacts on human health and well-being which depend on beneficial contact with nature. In response to this challenge, a variety of programs targeting the recruitment, reactivation, and retention of fish and wildlife-based recreationists have been developed. Because of the fundamental social and demographic changes in America that are driving much of the disconnection with nature and wildlife, however, the success of such programs is very uncertain. There is growing recognition that continuation of the conservation enterprise which oversees stewardship of our fish and wildlife resources will likely require more fundamental changes to broaden opportunities and inclusion for diverse communities.<br>A fundamental problem and opportunity in this endeavor is how to engage the communities that have not been actively encouraged to participate in nature- and wildlife-based activities. Extremely limited information exists concerning the value of and desire for experiences with nature and wildlife from African-American communities in Minnesota as well as the barriers that constrain African-Americans from desired experiences with nature and wildlife.The proposed project will collect information from African-American Minnesotans concerning their values, attitudes, experiences, awareness of, and preferences for learning about, experiencing, or conserving nature and wildlife. This information will be collected during a two-year period in two phases. The first year we will conduct focus groups and in depth interviews with members of the communities to develop a deep and nuanced understanding of their awareness of and connections to nature and wildlife. In the second phase, we will collect more broadly generalizable information from these communities through multi-modal social surveys using established psychometric approaches for measuring values, beliefs, attitudes, motivations, and experience preferences. This information will serve as foundational information across Minnesota for better engaging and understanding these communities. In addition, the information will assist natural resource management agencies to design programming, experiences, and services that match to the motivations and desired experiences of members of these communities. Doing so could increase their participation in nature- and wildlife-based activities and conservation behaviors.

Predicting from the past - identifying characteristics of invasion-resistant and invasion-prone waterbodies to aid horizon scanning	December 2024	Waterbodies in the Upper Mississippi River Basin are at high risk of invasion by several aquatic invasive species (AIS), with often devastating ecological impacts to water quality and economic consequences for water-related infrastructure and management. Yet understanding which sites are most prone to invasion, and by which species, is lacking, making it difficult for managers and policy makers to know where to focus prevention and mitigation efforts. Some waterbodies in the region have proved resistant to forecasted invasion, and these situations may provide clues as to the conditions and processes producing this apparent resistance. If patterns can be revealed, this would allow managers to more accurately predict invasion risk throughout the region and thus to triage sites for prevention and mitigation efforts. Additionally, such knowledge may allow managers to develop and apply strategies that promote resistance to invasion in other waterbodies. We will use a combination of machine learning and statistical modeling to leverage region-wide waterbody invasion histories and datasets on the physical, biological, chemical, anthropogenic, and geographic characteristics of these waterbodies to: a) identify that increase or decrease invasion risk, b) categorize all waterbodies in the region based on their invasion risk, and c) provide a decision support tools for managers and policy makers to identify at-risk sites.

Development of a Mississippi River Basin Invasive Carp Population Assessment Team	December 2021	Bighead (<i>Hypophthalmichthys nobilis</i>), black (<i>Mylopharyngodon piceus</i>), grass (<i>Ctenopharyngodon idella</i>), and silver carp (<i>H. molitrix</i>), collectively referred to as invasive carp, have caused a wide range of negative ecological, economic, and social impacts since their introduction to the United States and subsequent escapement and spread. As a result, the Aquatic Nuisance Species Task Force charged the U.S. Fish and Wildlife Service (Service) to develop a national management and control plan. With passage of the Water Resources Reform and Development Act of 2014 (WRRDA), Congress charged the Service with leading a multi-agency effort to slow the spread of invasive carp in the Upper Mississippi and Ohio river basins by carrying out activities designed to slow, and eventually eliminate, the threat posed by invasive carp. In addition, the Service is mandated by Congress to coordinate multi-agency efforts to manage and control invasive carp nationally, to report the effectiveness of these cooperative efforts, and to document progress implementing the National Plan and controlling the spread of invasive carp. In FY20, Congress expanded invasive carp control activities throughout the Mississippi River and its sub-basins, including the Lower Mississippi River, Arkansas-Red-White, Missouri River, Tennessee-Cumberland, Ohio River, and Upper Mississippi River sub-basins. To begin addressing this need, the Service formed an Ad Hoc Team with representatives from each sub-basin partnership and select federal agencies (see Appendix 1) to develop initial goals and objectives for an invasive carp population assessment and to identify an organizational structure, roles, responsibilities, and expectations that provide the necessary coordination and communication to develop a comprehensive basin wide approach for population assessment. This approach will be shared with the sub-basin partnerships and respective state management authorities and revised as needed based on input received.

Investigating Drivers of Cisco Recruitment	January 2024	The Great Lakes featured high abundances of Cisco (Coregonus artedi) until the early-1900s when their stocks began to collapse, with Lake Superior declining in the mid-1900s. Since that time, the stocks have rebounded in Lake Superior, although they once again appear to be in decline. The original decline in the mid-1900s was attributed to a variety of anthropogenic factors including overfishing, pollution, and introduced species. Even when stocks were abundant, it was noted that large spawning stocks did not necessarily lead to large recruitment classes and, similarly, small spawning stocks could sometimes result in large recruitment classes. Factors quantitatively linked to recruitment have been evaluated previously using Ricker stock recruitment models. We propose using three quantitative methods to investigate the relationship of biotic and abiotic factors with Cisco recruitment, including: (1) Multivariate Auto-Regressive State Space Models; (2) Empirical Dynamic Models; and (3) Bayesian Spatial Delta-glmm models. This work will be done in collaboration with local, federal, tribal, and state agencies working on Lake Superior. Our proposed outreach plan includes numerous meetings with stakeholders, presentations at professional societies, peer-reviewed publications, and quantitative workshops focused on teaching the three methods we will be applying. Building on hypotheses established by prior researchers, we will be looking at climatic and temperature variables, indices of predators, indices of competitors, indices of spawners, and measures of habitat quality.

Tracking bats and coronaviruses through NABat: Human dimensions of viral transfer	December 2025	<b>Background and Rationale</b><br>U.S. Geological Survey’s (USGS) Fort Collins Science Center (FORT) aims to initiate a new Research Work Order with the Minnesota Cooperative Fish and Wildlife Research Unit (MN Unit). The MN Unit will support a national-scale effort to track bats and coronaviruses through the North American Bat Monitoring Program (NABat). The NABat program was established in 2015 to provide reliable information on where North American bats occur and how their populations respond to current and future threats. Now in 2021, the NABat human infrastructure has grown to include a network of more than 160 partnering organizations including Federal, State, Tribal, and non-governmental organizations, community scientists and private industry collecting and submitting data across 49 US States and 8 Canadian provinces. NABat Monitoring Hubs help coordinate regional data collection efforts, provide technical assistance, and actionable science to local partners.<br><br>This work will provide an intense wildlife coronavirus surveillance effort conducted in partnership with Federal, State, Tribal, and non-governmental organization partners. Data obtained from coronavirus surveillance in bats and the environment will be used to model SARS-CoV-2 occurrence patterns and understand the role of wildlife and the environment in human COVID-19 infection dynamics. Data will also be collected on the human dimensions of the issue and how human perception and behavior influences risk. This will inform risk assessments on viral transfer between human and wildlife populations and would inform actions to help prevent or minimize recurrence of outbreaks in the future.<br><br>Bats are the evolutionary reservoir of diverse beta and alpha coronaviruses, including SARS-like coronaviruses. Betacoronaviruses closely related to SARS-CoV-1, MERS-CoV, and SARS-CoV-2 have been isolated in Rhinolophid bats in China, but relatively little is known about the diversity of coronaviruses in North American bat species. The scientific consensus remains that bats are the most likely reservoir host of SARS-Cov-2 and that human and bat contact is the most likely scenario for a spillover event that led to the COVID-19 pandemic. Understanding viral diversity, including and especially coronaviruses, in bats has profound implications for ensuring wildlife and human health and preparing for future zoonotic disease spilllover events. Furthermore, bats are known reservoirs of rabies virus and globally are known to be the reservoir hosts of other viruses that are highly pathogenic in humans, including Nipah virus and Hendra virus. Collection of guano from winter and summer colonies and swabbing of live bats would allow assessing viral diversity and loads, furthering our understanding of coronavirus and other potentially pathogenic viruses in North American bats. To compliment these data,<br><br>To date, empirical evidence is lacking on the prevalence of coronaviruses in naturally occurring populations of North American bats. This work will leverage and bolster the existing NABat collaborative monitoring network so that we can better track and predict occurrence of coronaviruses in North American bats.

Public acceptance and preferences for climate change adaptation in the Mid-West.	July 2025	The objectives of this study are to: 1) to understand public acceptance of climate change consequences and public preferences for climate change adaptation strategies and the stability of those preferences; 2) identify the key antecedents and consequences of stability of these preferences for climate change adaptation management strategies; 3) develop recommendations for engaging the public and stakeholders in developing climate change adaptation management strategies. Very limited knowledge exists about key public stakeholders’ (e.g., hunters, anglers, birdwatchers) perception of the conditions resulting from climate change to fish and wildlife resources or their preference for adaptation strategies to these changes. This limited understanding of public preferences has also impeded early, intensive interventions by resource managers to improve conservation outcomes. Recent research suggests that presentation of the uncertainty of consequences as well as information about the potential benefits of strategies can affect the trust the public has in information as well as preference for adaptation strategies and the malleability of those preference. We will use social psychological experiments embedded in online social surveys to clarify relationships among uncertainty, trust, preference, and key characteristics of respondents. Project reports, information workshops, and presentations will be provided and stored digitally on a project website for peer scientists at universities as well as fish and wildlife managers at state and federal agencies, tribes, and non-governmental organizations. In addition, 3 peer-reviewed journal articles will be developed for publication in respected journals. Key personnel include: 1) Dr. David C. Fulton (Principal Investigator), U.S. Geological Survey, Assistant Unit Leader, Minnesota Cooperative Fish and Wildlife Research Unit, and Adjunct Professor, University of Minnesota; 2) Dr. Olivia LeDee (Cooperating Investigator), U.S. Geological Survey, Midwest/Midcontinent Climate Adaptation Science Center, Adjunct Assistant Professor, University of Minnesota; 3) Post doc Research Fellow to be identified.

Genetic biocontrol of invasive species: understanding attitudes and risk perceptions.	December 2023	A web-based survey will evaluate Minnesotans’ attitudes and risk perceptions related to the use of genetic modification techniques for the control of invasive species. Very little is known about public attitudes or risk perceptions concerning the use of genetic modifications for aquatic invasive species control. The purpose of this proposed project is to better describe public understanding and attitudes towards the use of advance genetic modification techniques as control tools for invasive species. To thoroughly address the purpose, this research must investigate attitudes towards these techniques within the context of specifically understanding attitudes toward the invasive species and their impacts. Recent research on the human and social dimensions of invasive species provides guidance for the design of the proposed research. Although a robust literature concerning the human and social dimensions of invasive species management and governance has developed, there is limited research specific to the use of genetic techniques to control invasive species. The study proposed here addresses that gap in research. This study represents a crucial upstream evaluation of public attitudes and perceptions that will enable subsequent engagement to develop governance in the use of genetic technology for these purposes in Minnesota. This project will provide baseline information about Minnesota residents’ attitudes and risk perceptions toward genetic modification techniques as an approach for managing aquatic invasive species. The outcomes of this study include improving knowledge of the preferences and risk perceptions of using these techniques among the general population of Minnesota, tribal communities, and specific stakeholder and user groups such as anglers and boaters in the state. The focus will be on attitudes and risk perceptions toward using genetic modification to help control invasive species in general as well as two specific, widespread invasive species: common carp and zebra mussels. In addition, the project will help clarify the social psychological antecedents and consequences of these attitudes and risk perceptions. Focus groups and interviews will be used to assist survey design, and we will use mixed-modal surveys with web-based data collection. We will also implement a discrete choice experiment within the survey to better understand the attributes driving choices concerning the use of genetic technology. A total of 3,200 surveys are targeted for completion from the Minnesota general public, lakeshore homeowners, anglers, and boaters. The objectives of this study are: 1) to understand the attitudes, risk perceptions, and level of support for using genetic techniques in controlling two invasive aquatic species in Minnesota (e.g., common carp and zebra mussel); 2) to understand the antecedents/consequences to attitudes, risk perceptions, and level of support for using genetic techniques in these two specific cases; 3) to understand the general preferences for using genetic techniques in the management of invasive species in Minnesota, the antecedents/consequences of these preferences, and the population heterogeneity related to these preferences; 4) to explore and gain an initial understanding of potential concerns of tribal communities in Minnesota with using genetic techniques for invasive species control.

Assessing the motivations and constraints of lapsed small game hunters	June 2022	Rates of hunting participation are declining across the United States (U.S. Department of Interior, 2016). This decline has implications for the long-term financial health of state wildlife agencies that principally rely on hunting license revenues to support both game and non-game management activities. Consequently, understanding the factors that shape citizens’ patterns of participation in hunting, preferences and interest in hunting, and constraints to long-term engagement is critical for ensuring the current funding model employed by the agencies, fostering citizens’ connection to outdoor heritage, and wildlife conservation moreover. Growing emphasis has been placed on activities to recruit, retain, and re-engage hunters and anglers. However, limited scientific scrutiny has been directed toward these activities. Hunter recruitment and retention activities are enhanced with and understanding of the needs, preferences and differences of a diverse target population. For instance, constraints to participation in outdoor recreation have been shown to vary as a function of a variety of lifecourse attributes and socio-demographics including having children, household income, health, age, access to transport and social supports. Understanding the role of these factors, and others, in shaping citizens’ patterns of participation in hunting is critical for effective program design and outreach. Lapsed hunters, defined as individuals that have hunted in the past but have since ceased participation, are a demographic of particular interest for outreach efforts given their apparent existing interest in hunting generally. Enticing these individuals to return to hunting by facilitating the needed social, institutional and economic supports could be an effective strategy for bolstering participation. However, limited scientifically valid knowledge exists regarding the factors that cause hunters to otherwise cease participation, or strategies for alleviating these causes. The objective of this project is to conduct a survey to assess the factors that cause hunters to cease participation in small game hunting including social, economic and institutional constraints, and their likelihood to return to hunting.

Assessing deer hunter satisfaction and attitudes toward deer management, and Minnesotans’ values, beliefs, and attitudes toward moose and moose management	June 2023	This project will support two related studies on deer and moose management. Deer hunter attitudes and satisfaction survey–The Minnesota Deer Management Plan makes provisions for periodic assessment of hunters’ satisfaction with aspects of their deer hunting experience, and their trust in the Minnesota Department of Natural Resources deer management. Periodic measurement of these variables equips the agency with knowledge about constituents’ experience with deer hunting, and enhances their ability to make deer management decisions that improve constituents’ experience, while meeting deer management goals. Importantly, assessing deer hunters’ satisfaction, and making decisions based in part on that knowledge, helps build trust, which is identified as a goal in the plan. This study supports the goals articulated in the plan. The objective of the study is to conduct a survey of Minnesota deer hunters to understand the factors that affect their satisfaction with deer hunting, and their attitudes toward deer management. Survey of moose stakeholder--Minnesotans value moose (Alces alces) for a variety of reasons, and understanding those values is an important part of the DNR’s articulated vision for moose management. The Minnesota Moose Management Plan (Moose Management Plan, 2011) establishes an objective of integrating social science into moose management decisions. One strategy identified under this objective is to undertake an assessment of Minnesota moose stakeholders’ values, beliefs, attitudes, and behaviors related to moose, moose management, and moose harvest. In this study, we will conduct a survey of Minnesotans’ to support implementation of the 2011 Moose Management Plan, and generate data to inform an update to this plan slated to begin in FY22. Specific topics for assessment will emerge from deliberation with DNR staff and external partners during survey design. Potential topics for assessment include, Minnesotans’ willingness to pay for moose viewing opportunities, perceptions of moose hunting and moose harvest, tradeoffs in moose, wolf, and deer management in moose range, and preferences for the DNRs approach to moose management among others. The objective of this study is to conduct a survey of Minnesotans’ to understand their values, beliefs, attitudes, and behaviors about moose and moose management.

Bioacoustics for broad-scale species monitoring and conservation	December 2024	It is difficult to monitor many wildlife species over broad geographic areas, and such monitoring efforts are generally labor intensive and expensive. However, at regional and larger scales, information on species of conservation concern is necessary to make informed management decisions. With funding from the Minnesota Environmental Trust Fund, we are evaluating the usefulness of passive bioacoustic monitoring to assess distribution and abundance of red-headed woodpeckers, and other bird species of conservation concern, to inform conservation by providing an efficient means of monitoring across a broad geographic region.

Understanding perceptions of risk from chronic wasting for tribal communities in the Midwest	December 2024	The objectives of the project are to better understand key concerns and perspectives of tribes in Region 3 USFWS related to CWD management and CWD’s potential to impact hunting participation and the food security of tribal members for whom deer and elk are managed for hunting. Addressing CWD and its impacts will be a long-term, nationwide effort. This proposal will serve as a primary step to building essential knowledge about the potential for CWDs to impact the North American Model of Wildlife Management as well as for addressing CWD on tribal lands. We will use culturally appropriate ethnographic approaches to conduct indepth interviews and nominal group research to better understand tribal perspectives and indigenous knowledge concerning the risks of CWD to hunting opportunities, food security, and cultural practices (Daigle, Michelle, Ranco, and Emery 2019; Dockry, Hall, Van Lopik, and Caldwell 2016; Emery, Wrobel, Hansen, Dockry, Moser, Stark, and Gilbert 2014). Such systematic information concerning the perceived threat of CWD will be extremely useful to the tribes and wildlife management agencies in planning and prioritizing future research and management activities to address CWD and its impacts. Specifically, we will:<br> <br>1) Complete a systematic review of research and activities addressing the human dimensions of CWD to develop a state-of-the-knowledge summary of the topic; 2) Complete interviews and nominal groups workshops with tribal leadership and members across Region 3 USFWS affected or potentially affected by CWD; 3) Identify participants’ perceived risks of CWD to hunting, food security, and cultural practices; 4) Identify the Tribes indigenous knowledge and participants’ personal beliefs about research and management activities to address the perceived risks of CWD to hunting, food security, and cultural practices; 5) Identify participants’ prioritization for research and management activities to address the perceived risks of CWD to hunting, food security, and cultural practices; 6) Use the study results to help information management plans and programs at the federal, state and tribal levels design to address the threat of CWD to hunting and food security.<i> </i><br><i></i><br>The proposed project is the first step in assessing the key threats posed by CWD for hunting participation, cultural practices, and food security for Tribes in the Midwest. A better understanding of these threats and management actions to address such threats could help in the design of the federal, state, and tribal programs that are resilient to such threats. Results of the group workshops will provide useful information about CWD threats and potential management actions and will be crucial to designing long-term management programs and research efforts.	The scope of this study includes: 1) completing a systematic review to determine the state-of-knowledge concerning management activities and human dimensions research related to CWD and the use of Indigenous knowledge for wildlife management; and 2) identifying and prioritizing the key concerns and perspectives of tribes related to CWD in Region 3 USFWS. The outcomes of this study will be used to provide direction for future human dimensions research and management action on CWD relevant to tribal communities.
Minnesota residents’ attitudes toward wolves & wolf management	June 2020	The Division of Fish and Wildlife is engaged in an update to the Minnesota Wolf Management Plan. Public input and engagement are at the forefront of these efforts. Understanding the values, beliefs, attitudes, and behaviors of stakeholders can enhance the legitimacy and efficacy of agency decisions with respect to wolf management, while helping to minimize conflict. We propose to assess stakeholder attitudes toward wolves in Minnesota in general, their preferences for potential management priorities, their values toward wildlife, preferred options for funding wolf management, and tolerance of wolves on the landscape.	Wolves are currently listed as a federally threatened species in Minnesota. However, the species will likely be delisted soon and management responsibility for the wolf will move to the Minnesota Department of Natural Resources.

Understanding the values, beliefs, attitudes, and behaviors of stakeholders can enhance the legitimacy and efficacy of agency decisions with respect to wolf management, while helping to minimize conflict. We propose to assess stakeholder attitudes toward wolves in Minnesota in general, their preferences for potential management priorities, their values toward wildlife, preferred options for funding wolf management, and tolerance of wolves on the landscape. This information is important for ensuring that the Minnesota Wolf Management Plan is effective and responsive to public interests.
Assessing attitudes toward chronic wasting disease	June 2021	The emergence of chronic wasting disease (CWD) in wild deer in Minnesota, and declining deer hunter participation, are topics of concern for the Minnesota DNR. Consequently, greater capacity to conduct studies that support decision making associated with white-tailed deer management has been identified as an area of need. This proposal supports a Ph.D. student position at the University of Minnesota, housed in the Cooperative Fish and Wildlife Research Unit to conduct human dimensions studies on CWD, deer hunters, and white-tailed deer management.	Chronic wasting disease is an infectious disease of animals belonging to the family cervidae including deer, elk, moose and caribou. Since 2002, CWD has been found in wild deer populations and captive deer farm facilities throughout the Midwestern United States, including Minnesota. The disease is always fatal and represents a significant threat to the long-term health of wild deer populations, and the future of deer hunting opportunity where it is found. Identifying effective avenues for disease management is a concern for the Minnesota Department of Natural Resources. Many of the identified solutions for CWD containment, risk management, and elimination require the voluntary participation of statewide deer stakeholders including hunters, landowners, and the general public (Minnesota Chronic Wasting Disease Response Plan, 2019). This project will support several studies designed to better understand hunter, landowner, and public beliefs about, attitudes toward, and perceived risks of CWD and their support of management actions and policies to address CWD in Minnesota. This human dimensions information will be integrated with ecological information to develop effective strategies to address CWD in Minnesota. Th expected outcome of the research is to help minimize CWD impacts on deer and deer hunters in Minnesota.
Red-headed woodpecker: indicators of oak savanna health	June 2021	The red-headed woodpecker (Melanerpes erythrocephalus) is the flagship species of the oak savanna ecosystem. It plays a crucial role in maintaining healthy oak savanna by creating habitat for other species in live and dead trees. Historically, red-headed woodpeckers were common across the Midwest, but populations have experienced dramatic regional declines estimated at 67% since 1970. The situation in Minnesota is even grimmer: since 1967, this species has experienced an average annual decline of 6%, representing a cumulative loss of nearly 95% of the population. Although the rate at which red-headed woodpeckers are declining has slowed since 1990, populations in Minnesota do not appear to have stabilized. Our goals are to address population declines in a charismatic species of great conservation concern, to assess the outcomes of ongoing management and conservation efforts in an endangered ecosystem, and to develop a unified management plan for restoring oak savanna for red-headed woodpeckers and other oak habitat specialist species in Minnesota and throughout the Midwest.	The red-headed woodpecker (Melanerpes erythrocephalus) is the flagship species of the oak savanna ecosystem. Red-headed woodpeckers are considered ecosystem engineers and a keystone species, and their presence may have far-reaching effects on species richness and ecosystem health. Historically, red-headed woodpeckers were common across the Midwest, but populations have experienced dramatic regional declines estimated at 67% since 1970. We are seeking to (1) Identify oak savanna habitat characteristics and adult condition and behaviors associated with successful production of young, the factors related to whether and where individuals migrate, and the consequences of migratory status on productivity and survival and (2) Develop a long-term management plan for restoring oak savanna to support red-headed woodpeckers and other oak-savanna habitat specialists in Minnesota and the Midwest. Project partners include the University of Minnesota Cedar Creek Ecosystem Science Reserve, the University of Toledo, and the Minneapolis Chapter of the Audubon Society. Results of this research will help inform management of oak savanna ecosystems and provide insight into factors that influence population ecology of red-headed woodpeckers and the rare ecosystems in which they function.
Minnesota trumpeter swan migration ecology and conservation	June 2024	Trumpeter swans (Cygnus buccinator) have high intrinsic and economic value in Minnesota as a protected wildlife species. MN citizens enthusiastically invested in the restoration of trumpeter swans through the check off donation and other funding sources to the MN Department of Natural Resources (MNDNR) Nongame Program since the mid-1980s. The Interior Population of trumpeter swans (of which MN swans comprise ~63%) has increased dramatically since they were re-established in the 1960s and 1970s and both population size and distribution have expanded significantly in Minnesota since the MNDNR Alaska-egg project began in 1986. The original MN reintroduction goal of 15 breeding pairs and the revised interim goal of 500 individuals by 2001 have been greatly exceeded, with a current estimate of nearly 17,000 swans (an average annual finite rate of increase of ~1.20 since 2000). Better understanding of trumpeter swan ecology will be extremely useful in developing future management strategies for this growing population.	The Interior Population of trumpeter swans (Cygnus buccinator) was re-established through reintroduction efforts beginning in the late 1960s. Since that time, the population has exceeded reintroduction goals and now numbers more than 25,000 individuals with an estimated growth rate in Minnesota of circa 1.20 (i.e., a doubling time of ca. 5 years). As this population moves from rare to abundant across much of the Upper Midwest, a lack of information regarding basic ecology hinders planning for long-term management. In this project, we are marking Interior Population trumpeter swans with GPS-GSM transmitters to (1) Evaluate year-round swan movements, (2) Determine whether and where trumpeter swans make molt migrations, (3) Evaluate year-round habitat use and selection patterns of trumpeter swans, and (4) Evaluate survival rates of trumpeter swans, if sample sizes are adequate and fates (i.e., mortality events) can be determined. In addition, we are evaluating the current genetic structure of this population, and assessing environmental lead exposure. Partners include the University of Minnesota, the U.S. Fish and Wildlife Service, the Canadian Wildlife Service, Manitoba Conservation, the Minnesota Department of Natural Resources (DNR), the Wisconsin DNR, the Michigan DNR, the Iowa DNR, the Great Lakes Indian Fish and Wildlife Commission, and the Trumpeter Swan Society. Information resulting from this study will help guide future trumpeter swan management across the western Great Lakes region.
Minnesota Statewide Angler Survey	January 2019	The Minnesota DNR Fisheries is interested in monitoring of angler preferences for management strategies and policies at a statewide level every few years. This project collects data from a sample of 2000 anglers in 5 geographical defined strata to help identified trends and determine current preferences.	Fisheries management inherently involves assessing both fish populations and human demand and use of those fish populations. The Minnesota DNR Fisheries is interested in monitoring of angler preferences for management strategies and policies at a statewide level every few years. This project collects data from a sample of 2000 anglers in 5 geographical defined strata to help identified trends and determine current preferences. The study also uses MaxDiff modeling to identify stakeholder priorities with Minnesota fisheries management. We are collaborating closely with Minnesota DNR fisheries researchers and managers on this project. Findings from this study will be used to develop acceptable fisheries management policies. In addition, the study will identify key management issues that could lead to stakeholder conflict about Minnesota fisheries management in the future.
Human Dimensions of Wildlife Research Associate	June 2021	The Minnesota DNR Wildlife has a high demand for research related to stakeholder and public attitudes and behaviors related to management programs, issues, and policy preferences. This project provides funding for a research associate and operating funds to address to key issues related to wildlife management in Minnesota such as Chronic Wasting Disease Management.	The Minnesota DNR Wildlife has a high demand for research related to stakeholder and public attitudes and behaviors related to management programs, issues, and policy preferences. Such social science is seen as essential by the Minnesota DNR to assist in making critical planning and management decisions. Two issues of primary concern are Chronic Wasting Disease Management and Wolf Management Planning. This project provides funding for a research associate and operating funds to address assist the Minnesota DNR in developing long-term strategies for addressing the threat of Chronic Wasting Disease to both deer populations in Minnesota and to hunter participation. In addition, this project will assist the Minnesota DNR in developing a revised management plan for wolves in Minnesota as management responsibility for the species has devolved to the state. This information is critical to Minnesota DNR decision making concerning disease management and population management policies. The social science information will be integrated with ecological information to ensure competent decisions that are broadly supported by the Minnesota public.
Modeling with long-term datasets to inform management of National Park grasslands	December 2018	Large ungulates in northern Great Plains national parks are of special management concern. This project uses existing data to better understand species interactions and environmental factors that influence ungulate population ecology.	Large ungulates in northern Great Plains national parks are of special management concern. Several parks annually acquire information on ungulate condition and population size, along with environmental data, and data on other herbivores. To date, these data have not been integrated into models or other structures that can be used to inform decision making. We used existing data to better understand species interactions and environmental factors that influence population ecology of ungulates and other grazers in the northern Great Plains. We conducted this assessment with collaborators in the U.S. National Park Service and the University of Minnesota. Results of this project can be used to inform management in national parks and other landscapes in the northern Great Plains.
Private Landowner Participation in the Walk-In Access (WIA)	September 2018	The purpose of this study is to better understand private landowners within the 46 counties eligible for the WIA Program who participate in or have the potential to participate in the WIA Program by enrolling land in the program. Specific objectives of the study include determining: 1) landowner perceptions of constraints and barriers to participating in the program; 2) key social, economic, attitudinal and motivational antecedents to enrolling eligible land; 3) key attributes that define the preferences of landowners for choosing to participate in a WIA Program; and 4) spatial and other geographic characteristics that predict land enrollment. The information collected in the study will provide a better understanding of the variables that best predict landowners’ decisions to enroll property and facilitate development of a spatially explicit model that can help managers better understand which landowners have the highest potential for participating in the WIA Program in the future.

Evaluating nest-site selection of Arctic peregrine falcons in the Colville River Special Area	July 2019	One fourth of Alaska's Arctic peregrine falcons, a formerly federally threatened species, nest along the Colville River on Alaska's North Slope. We are using historical survey data and models we developed related to productivity to assess where this population would be most and least susceptible to perturbation, to inform management decisions.	One fourth of Alaska's Arctic peregrine falcons, a formerly federally threatened species, nest along the Colville River on Alaska's North Slope. Since their recovery and removal from the endangered species list, the Colville River Arctic peregrine population has increased substantially, although there is considerable variation in reproductive success and reproduction. We used historical survey data and models we developed related to productivity to assess where this population would be most and least susceptible to perturbation. Collaborators included the U.S. Bureau of Land Management and the U.S. Fish and Wildlife Service. Results of this study can be used to refine management strategies for Colville River Arctic peregrines that minimize potential population impacts from anthropogenic factors.
Restoration of elk to northeastern Minnesota	June 2019	This research will determine areas of suitable habitat and levels of public support for restoring elk to Northeastern Minnesota. Research will be conducted in an area already identified as having local public interest and abundant public forest land (i.e., southern St Louis, Carlton, and northern Pine counties; Figure 1). The research team will build upon existing eastern elk restoration research to address two research goals:<br><br>1) Identify the amount of public support for a restored elk population by surveying citizens in and around the prospective restoration sites.<br><br>2) Determine where suitable habitat exists and how many elk it could sustain. Combine the public support and habitat suitability maps to identify areas likely to support a restored elk population.	Elk (Cervus canadensis) were historically present in Minnesota, but were extirpated from the state at the beginning of the 20th century.

Insecticide exposure risk for grassland wildlife on public lands	December 2019	Routine application of insecticides in agricultural landscapes has the potential to expose grassland wildlife on public lands to chemicals that could influence survival and reproduction. We are evaluating this risk on Minnesota Department of Natural Resources property in southwestern Minnesota.	Routine application of insecticides in agricultural landscapes has the potential to expose grassland wildlife on public lands to chemicals that could influence survival and reproduction. In particular, application of insecticides to control soybean aphids is thought to potentially influence grassland birds both directly and indirectly. We evaluated this risk on Minnesota Department of Natural Resources property in southwestern Minnesota that is managed for wildlife by assessing potential direct and indirect (through food resources) exposure of grassland birds to operational insecticide application, and be measuring chemical deposition. To conduct this assessment, we partnered with the Minnesota Department of Natural Resources with support from the State of Minnesota Environmental and Natural Resources Trust Fund. Results of this research will help managers better design and manage public grasslands embedded in agricultural landscapes for wildlife.
Minnesota fish habitat survey	December 2015	This study is being conducted to understand angler beliefs and perceptions about fish habitat. This information will inform how the DNR can better connect the importance of habitat to sustainable fisheries management. Surveys were distributed to 2,000 resident anglers. A total of 784 full-length surveys were returned, resulting in an adjusted response rate of 41.7%. An additional 80 shortened or late surveys, used to gauge nonresponse, were returned for a total response rate of 46.0%. Respondents had fished in Minnesota for about 40 years, and purchased a Minnesota fishing license an average of 8 of the past 10 years. Respondents fished 24 days in the past year. Respondents rated their preferences for targeting 20 fish species; walleye was the most preferred species while carp and bullhead were least preferred. Respondents were asked to report their overall satisfaction with the overall fishing experience, along with six other specific aspects of fishing. Respondents were most satisfied with the overall fishing experience and access, and least satisfied with the number of fish they caught and the behavior of non-anglers (M=3.2 Respondents were asked how much they agreed with a series of 14 statements about fisheries-related values. Protection related values were rated highest (3.6 on a 5-point scale), compared to utilitarian (2.5) and human dominance (2.6) values.	None
Minnesota waterfowl hunters	January 2016	Minnesota has generally been in the top 3 states for number of waterfowl hunters in the United States. In recent years we have expanded efforts to obtain quantitative information about opinions and motivations for this important clientele. Minnesota participated in the North American Duck Hunter Survey and Minnesota hunter responses were compared to those in other States. More recently, reports documenting hunter activity and opinions following the 2000, 2002, 2005, and 2007 waterfowl hunting seasons were completed. A survey following the 2010 season is currently being analyzed. In addition, a series of surveys looking at hunter recruitment and retention were completed following the 2005 waterfowl hunting season (Schroeder et al. 2007b,c,d) and a study of former waterfowl hunters was completed following the 2009 season. Information from these reports has been used to inform management decisions. We conducted a surveys following the 2010 and 2011 waterfowl seasons. This study will allow continued long-term monitoring of trends in hunter satisfaction and attitudes toward management.	None
Minnesota northern pike regulations	June 2016	Northern pike (Esox lucius) is the most widely distributed and one of the most popular game fish in Minnesota, with more than one-third of resident anglers indicating that they specifically target pike. In 2010, the Minnesota Cooperative Fish and Wildlife Research Unit conducted a survey for the Minnesota DNR of resident pike anglers and darkhouse spearers in the Minnesota in order to understand the regulatory and site experiences and preferences of pike anglers and spearers (Schroeder & Moeckel 2011). This information was important in developing long range plans for managing pike in Minnesota. Schroeder and Fulton (2014) used these data to compare the regulatory preferences of anglers and dark house spearers. The Minnesota DNR has a current need to update this information and collect additional stated preference choice information concerning size and bag limit regulations for northern pike in different regions of Minnesota. The purpose of this proposed study is to: 1. Characterize the preferred experiences, level of involvement, catch orientations, satisfaction, use histories, management and regulatory preferences, and sociodemographics of Minnesota resident pike anglers and darkhouse spearers; 2. Examine the fishing site choices and lake and regulatory attributes that influence the site choice decisions of pike anglers and spearers. 3. Compare the information in 1 & 2 above between darkhouse spearers and pike anglers across 3 geographical strata in Minnesota. The sample was selected from DNR electronic licensing files for purchasers of Minnesota fishing licenses. The sample was stratified based on fishing method (angling or spearing), geographic residence and on expressed geographic preference of pike anglers/spearers to target pike in Minnesota. A total of 6 strata ( n = 400 completed surveys in each stratum, total n = 2400 completed surveys) were targeted including anglers fishing in the 1) northern, 2) central and 3) southern regions of the state, and spearers fishing in the 1) northern, 2) central and 3) southern regions of the state. The stratified sample of spearers was drawn based on purchase of a darkhouse spearing license. This proposal will cover the cost of 4 strata. The angling sample was developed through a two stage sampling design. We first contacted a sample (n = 20000) of Minnesota anglers to identify those who fish for northern pike in Minnesota. We then targeted those who fish for pike in the second round of the study. Because approximately 30% of anglers target pike, and we anticipated ~30% response rate to the initial contact, an initial mailing of n = 20,000 allowed us to target about n = 1900 pike anglers in the final survey.

Landowner attitudes toward elk	December 2016	Through restoration efforts and immigration from Manitoba and North Dakota, there are currently about 150 elk in northwest Minnesota. In 1987, legislation was passed that required the DNR to write an elk management plan that recognized the value and uniqueness of elk, provided for integrated management, afforded optimum recreation opportunities, and restricted elk to nonagricultural land in the state. Currently, DNR staff is working with public stakeholder teams to develop a revised elk management plan, and anecdotally, it appears that interest in Minnesota elk has been increasing in recent years. The long-term vision of DNR for elk management is to enhance the population size and range extent of Minnesota's elk while maintaining coexistence with private landowners. DNR lacks objective data about the attitudes of private citizens toward elk. This inhibits the responsible advancement of elk management in the state. Minimizing future elk-human conflicts is critical to the successful expansion of elk since they utilize habitats on public and private lands. Although multiple states east of the Rocky Mountains have initiated elk restoration efforts, the primary literature lacks information pertinent to understanding the preferences of private landowners for elk management in an agricultural landscape. Citizens in northwest Minnesota have personally experienced living with elk, elk management, and elk-related tourism. They represent an ideal survey population to provide an understanding of the attitudes of private landowners toward elk in Minnesota. By learning more about their experiences, we may anticipate future conflicts if the range of elk expands in Minnesota, identify opportunities for education and partnering, and integrate data about landowner attitudes into modeling of additional areas suitable for elk. The objective of this study is to determine the attitudes of landowners within the elk range toward elk and their preferences for future elk management. The study will focus on the townships in northwest Minnesota encompassing the present range of elk. There are approximately 1,200 private landowners with >10 acres of land in this area. We will mail surveys per the 'traditional mailing' design to ensure adequacy, reliability and efficiency of the survey.	None
Long-term research and monitoring of human dimensions information on fisheries and wildlife management issues in Minnesota.	December 2016	This project is the continuation of a long-term research effort established in 2002 that provides funding for a full-time research fellow to work closely with Minnesota Department of Natural Resources fisheries and wildlife researchers and managers to collect timely information to assist in the evaluation of management programs. The primary focus of this position is on developing experience-based management information for fisheries and wildlife management in Minnesota and to use this information to further understanding of what factors influence angler and hunter experience satisfaction and level of support for management programs. This project provides a consistent process to develop a long-term database to improve understanding of factors influencing trends in both recreational participation in fisheries and wildlife-based activities and to examine how attitudes and beliefs about fish and wildlife management issues are changing over time. This project provides a unique contribution nationally by providing a long-term research program with consistent measurement that will allow examination of long-term trends in values, attitudes, and behavior from a theory-directed perspective.

Visitor use of Wildlife Management Areas	December 2016	The DNR, Section of Wildlife manages over 1,400 wildlife management areas (WMA) totaling more than 1.3 million acres. WMAs are part of Minnesota's outdoor recreation system and are established to protect those lands and waters that have a high potential for wildlife production, public hunting, trapping, fishing, and other compatible recreational uses. They are the backbone to DNR's wildlife management efforts in Minnesota and are key to: 1. Protecting wildlife habitat for future generations, 2. Providing citizens with opportunities for hunting, fishing and wildlife watching, and 3. Promoting important wildlife-based tourism in the state. WMAs range from prairies and wetlands to forests and brushlands. They provide opportunities for hunting, fishing, trapping, and wildlife watching activities. Wildlife resources and habitat are very important to Minnesota; 500,000 Minnesotans hunt and 1.6 million watch wildlife, one of the highest participation rates in the country. Combined, hunting and wildlife watching are over a $1 billion dollar industry in Minnesota (U.S. Census Bureau, 2011). Some research has been conducted in Minnesota on lands open to public hunting. Vlaming et al. (2003) measured use on Federal Waterfowl Production Areas (WPA) and found that most visited them to hunt. Cross (2014) surveyed Walk-In Access (WIA) users and found that respondents also hunted WMAs and found them more crowded. However, use of WMAs and WPAs was higher for all species hunted, as compared to WIAs. While agency staff agree WMA use is high, little data exists to quantify and categorize either consumptive or non-consumptive uses. These data are particularly important to determine not only uses, but species hunted, effort, distribution of uses, and economic considerations (e.g., travel cost, local economic impact). For each survey, the first 2 mailings will be comprised of an invitation to complete a survey online, and the third mailing will be a traditional self-administered mail-back questionnaire. All use of private data will adhere to MN DNR data privacy standards. No requests for state ELS data are required to complete this work order. The objectives of this study are to assess, 4.1) Seasonal visitor uses and characteristic of users 4.2) Visitor activities, experiences, and attainment of experiences 4.3) Visitor knowledge of and attitudes toward wildlife management areas 4.4) Economic benefits of wildlife management areas to local communities The potential respondent population includes any visitor, 18 years of age or older, to the WMAs that will be selected for study. WMAs will be selected at random throughout DNR Regions 1 and 4. Driving routes will be selected that maximize WMA visits and minimize travel distance. The WMA GIS layer will be used to identify WMA access points and drivers will be instructed to look for parking lots and pullout areas around the entire WMA. Temporary technicians, managed by the contractor, will drive those routes to solicit study participants. When the driver sees a vehicle parked around the WMA, they will place a numbered card and a cover letter in a waterproof pouch and affix the pouch under the vehicle's windshield wipers. The cover letter will explain the nature of the study and ask if they would be willing to share their opinions about WMAs. The card will be a business reply postcard that asks for the size of the party and individual's names, addresses, and phone numbers that can be used to contact them later about the study. Visitors who are present in the parking areas will be approached, explained the nature of the study, and postcard information will be collected onsite. Visitors will be informed that their participation was voluntary. Drivers will also instructed to distribute cards to all vehicles and groups they encounter. We will mail follow up surveys per the 'traditional mailing' design in the approach discussion of adequacy, reliability and efficiency above. This study includes up to 10 seasonal technicians to drive the routes and solicit participation in the study and a graduate student (MS level) at the University of Minnesota.	None
Assessing the preferences of stakeholders and waterfowl management professionals to inform the implementation of the NAWMP Action Plan	September 2018	This project addresses three key research activities associated with a broader proposal by the National Flyway Council’s Human Dimensions Working Group (HDWG) to conduct research involving key stakeholders and the general public in the U.S. and Canada that will inform implementation of the NAWMP Action Plan. The broader objectives are to: 1. Assess what hunters and other waterfowl conservationists (i.e., members of organizations supporting migratory bird conservation including viewers) most desire from their natural resource based management and social settings to inform NAWMP objectives and select habitat and population management alternatives. 2. Establish baseline measures that can be repeated to inform the development of a Public Engagement Strategy and monitor trends in achieving the NAWMP goal of “growing numbers of waterfowl hunters, other conservationists, and citizens who enjoy and actively support waterfowl and wetlands conservation.” 3. Assess waterfowl hunters’ knowledge, preferences, levels of use, and support for waterfowl and wetlands conservation. 4. Assess other waterfowl conservationists’ knowledge, preferences, levels of use and support for waterfowl and wetlands conservation. 5. Assess the general publics’ awareness and their perceptions regarding the importance of the benefits and values (i.e., Ecological Goods and Services - EGS) provided by waterfowl and wetlands conservation. 6. Assess the general publics’ participation in waterfowl-associated recreation and how much they support waterfowl and wetlands conservation. 7. Assess waterfowl professionals’ perspectives on the levels of waterfowl populations and habitats needed to support hunter and viewer use opportunities. In summary, two continental U.S.-wide surveys will be conducted with waterfowl hunters and other waterfowl recreationists. The proposed research will be conducted in coordination with other research conducted by the U.S. Geological Survey’s Fort Collins Science Center and by researchers in Canada. Expected outcomes: 1) Quantified waterfowl management professionals’ preferences regarding the desired future states relative to the three goals of NAWMP. 2) Quantified stakeholder preferences regarding what they desire in regards to their recreational experiences (hunting and viewing). 3) Foundations to develop explicit and transparent population, habitat, and people objectives (or at least define the tradeoffs) based on the quantified expressed preferences of waterfowl management professionals and stakeholders. 4) Foundations to select management alternatives that are most responsive to stakeholder desires and most likely to help achieve NAWMP objectives relating to people. 5) Segmentation of stakeholder groups based on types of participation (e.g., viewing and/or hunting), geographic location, engagement in conservation, knowledge of waterfowl and/or ecological goods and services of waterfowl habitats, and demographic characteristics. 6) Quantification of the general public’s participation in waterfowl and wetlands based activities, their awareness and perceptions of ecological goods and services and their evaluation of the	Managing waterfowl and the wetlands that sustain is a fundamental management challenge in North American. Broad management objectives and policies are defined by the North American Waterfowl Management Plan (NAWMP). This project addresses three key research activities associated with a broader proposal by the National Flyway Council’s Human Dimensions Working Group (HDWG) to conduct research involving key stakeholders and the general public in the U.S. and Canada that will inform implementation of the NAWMP Action Plan. The research identifies preferences of waterfowl hunters and birdwatchers on key attributes related to their recreation activities. Data were collected throughout the four flyways in the U.S. and Canada. This project is a broad collaborative effort across all US states and Canadian provinces, US Geological Survey, US Fish and Wildlife Service, and key NGOs including Ducks Unlimited. The project will provide critical information for establishing future long-term objectives for the North American Waterfowl Management Plan.
Patterns and trends in concentrations of lead in bald eagles in the Upper Midwest	September 2016	As high-trophic level predators, bald eagles are sensitive to accumulation of environmental contaminants. How lead accumulates through the food chain to bald eagles ins not well understood, and the results of this investigation will help identify patterns in lead concentrations in bald eagles in the Upper Midwest.	As high-trophic level predators, bald eagles are sensitive to accumulation of environmental contaminants. How lead accumulates through the food chain to bald eagles ins not well understood. Lead toxicity is a leading cause of eagle mortality, but lead also appears in sub-lethal levels in nestlings. We used measures of lead levels in nestling bald eagles to assess exposure levels and elucidate the likely mechanisms for accumulation in Upper Midwest national parks in collaboration with the National Park Service.

DOI: 10.1007/s13146-010-0037-y. \| Abstract	December 2010	Karst aquifers are important groundwater resources, but are vulnerable to contamination due to relatively rapid subsurface transport. Springs, points where the landscape and water table intersect and cold groundwater discharges, link aquifer systems with land surfaces and water bodies. As such, in many regions, they are critical to the viability of lakes, streams and cold-water fish communities. An understanding of where springs are located is important to watershed, fishery and environmental management efforts in karst regions. To better understand spatial distribution of springs and as a potential method for identifying variables that characterize locations of springs for improved land and watershed management, a nearest neighbor analysis and a discriminant function analysis (DFA) of springs were conducted in Winona County, Minnesota, USA, a karst landscape. Nearest neighbor analysis examined the spatial spring distribution. Twenty-two variables describing the locations of springs were analyzed to ascertain their ability to discriminate correct aquifer unit or bedrock unit classification for each spring. Springs were clumped with the highest densities in the lowest elevations. Springs were correctly assigned to aquifer units and bedrock units with eight and 11 landscape variables, respectively. Forest land cover was the only land cover type contributing to spring discrimination. Consideration of upland human activities, particularly in forested areas, on spring discharge along with a better understanding of characteristics describing spring locations could lead to better management activities that locate and protect springs and their important contributions to regional ecohydrology.

Fisheries Research. https://doi.org/10.1016/j.fishres.2022.106317 \| Abstract \| Download	December 2022	The International Commission for the Conservation of Atlantic Tunas (ICCAT) concluded the Atlantic Ocean tropical Tuna Tagging Programme (AOTTP) in 2021. This project had the objectives of enhancing food security, stimulating economic growth, and improving management through research on tropical tuna resources in the Atlantic Ocean, including bigeye tuna (Thunnus obesus). Here, we combine tagging data and otolith data from the AOTTP program, Panama City Lab and the Pelagic Fisheries Lab at the University of Maine with historical tagging data and otolith data from ICCAT and other sources to fit integrated growth models with the goal of providing the most complete growth curve (in terms of data inclusion and validation of age-at-length) for bigeye tuna in the Atlantic Ocean. Both Richards and von Bertalanffy growth models were fitted. A variety of models were fitted to subsets of the data to investigate the consistency of growth information. In all cases for the integrated model, the Richards and von Bertalanffy models were very similar with the von Bertalannfy model being preferred for parsimony. The preferred model, based on fit to old fish, was the von Bertalanffy curve based on length-age pair data from multiple sources. The addition of tagging data to create an integrated model showed patterns of lack of fit to both the tagging and otolith data suggesting conflict between the tagging and otolith data. The preferred model (length-age pair data only) gave the estimates: asymptotic length L∞ (fork length) equals 161.21 cm (95% bootstrap CI 154.39, 166.84), growth parameter K equals 0.392 yr− 1 (95% bootstrap CI 0.355, 0.441), and the time-axis intercept t0 equals − 0.239 yr (95% bootstrap CI –0.306, − 0.175). For the best fitting integrated model, the asymptotic length L∞(fork length, in cm) was estimated to be 185.78 (SD 6.298), the growth parameter K was 0.252 yr− 1 (SD 0.014), and the time-axis intercept t0 was − 0.524 yr (SE 0.025). The value for asymptotic length L∞ from the integrated model was larger than the lengths of all the old fish in the sample whereas the value for the curve based on otoliths passes through the cloud of points for old fish.

Ecological Indicators 10:781-788. \| Abstract	March 2010	The index of biotic integrity (IBI) is a commonly used bioassessment tool that integrates abundance and richness measures to assess water quality. In developing IBIs that are both responsive to human disturbance and resistant to natural variability and sampling error, water managersmust decide how to weigh information about rare and abundant taxa, which in turn requires an understanding of the sensitivity of indices to rare taxa. Herein, we investigated the influence of rare fish taxa (within the lower 5% of rank abundance curves) on IBI metric and total scores for stream sites in two of Minnesota’smajor river basins, the St. Croix (n = 293 site visits) and Upper Mississippi (n = 210 site visits). We artificially removed rare taxa from biological samples by (1) separately excluding each individual taxon that fell within the lower 5% of rank abundance curves; (2) simultaneously excluding all taxa that had an abundance of one (singletons) or two (doubletons); and (3) simultaneously excluding all taxa that fell within the lower 5% of rank abundance curves. We then compared IBI metric and total scores before and after removal of rare taxa using the normalized root mean square error (nRMSE) and regression analysis. The difference in IBI metric and total scores increased as more taxa were removed. Moreover, when multiple rare taxa were removed, the nRMSE was related to sample abundance and to total taxa richness, with greater nRMSE observed in samples with a larger number of taxa or sample abundance. Metrics based on relative abundance of fish taxa were less sensitive to the loss of rare taxa, whereas those based on taxa richness were more sensitive, because taxa richness metrics give more weight to rare taxa compared to the relative abundance metrics.

Ecological Indicators 36:178-185. \| Abstract	January 2014	Aquatic macrophytes shape trophic web dynamics, provide food and refuge for macroinvertebrates and fish, and increase nutrient retention, sediment stabilization, and water clarity. Macrophytes are well-suited as indicators of ecological health because they are immobile, relatively easy to sample and identify, and respond to environmental stressors on an ecological time scale. Aquatic plant monitoring programs can provide valuable information to water resource managers, especially in conjunction with macrophyte-based indices of biotic integrity (IBI). However, there are several current sampling designs and the precision of IBI scores has not been evaluated across different surveys. We evaluated the performance of the Minnesota macrophyte-based IBI for two survey designs; a point intercept (PI) survey and a belt transect (BT) survey. PI surveys are time intensive, whereas BT are less time intensive and have been used historically in Minnesota. Our objectives were to compare the PI surveys with BT surveys on the same lakes, and to modify the BT survey (MT survey) to improve information obtained from BT surveys. BT surveys consistently overestimated IBI scores compared to the PI method (t = 6.268, df = 60, p < 0.001). Overall IBI scores calculated from MT surveys differed significantly from PI scores, but on average, MT surveys predicted scores only 3% lower than PI scores. Implementation of the Minnesota macrophyte-based IBI through the adoption of the MT survey approach would improve sampling efficiency and enable widespread documentation of the effects of landscape change, shifts in hydrologic regimes, and other anthropogenic activities on the integrity of lacustrine systems.

Smith, Kyle, A.C. Landon, D.C. Fulton. A self-determination approach to understanding leisure identity salience among lapsed hunters. Leisure Science. \| Abstract	June 2023	This study extended a framework based on self-determination theory (SDT) to study hunting identity salience in lapsed hunters. SDT suggests that multiple forms of motivation can influence levels of self-determination and subsequent behavioral intentions and addresses how social-contextual factors support or thwart individual satisfaction of needs. In the context of hunting, SDT posits that individuals initially interested in the activity will habitually seek out positive hunting experiences and, when supported, will integrate deer hunting as part of their identity. Data were drawn from a survey of lapsed hunters in Minnesota, United States conducted during the winter of 2021. Results suggested that socio-contextual constraints were negatively associated with intrinsic motivation and support amotivation. Subsequently, these differing forms of motivation had a variable influence on identity salience. These findings have implications for recruitment, retention, and reactivation (R3) efforts and highlight the need to understand the influence of social-contextual factors and individual motivation in the context of continued hunting participation.

Human Dimensions of Wildlife. \| Abstract	March 2024	Motivation is a topic that receives substantial interest across the social sciences. However, in the human dimensions literature, scholars have primarily treated motivation as a unitary construct defined by the individual's desired goal state. In contrast, self-determination theory (SDT) suggests that multiple forms of motivation can influence levels of self-determination, integration of identities, and subsequent behavioral intentions, and has been utilized in multiple realms to understand human behaviors. SDT forms a consistent and well-understood mechanism for human psychological development and optimal function and allows for the formulation of out-of-sample prediction, a cornerstone of science. In this manuscript, we review the basic theories that make up SDT and provide insight for its application to human dimensions of wildlife research.

Males defend territories to attract mates in a lek-like reproductive strategy. Prior studies have documented rapid declines in populations with FSA associated fisheries. This study examines the migratory behavior and spatial ecology of adult male Tiger Grouper in Little Cayman, Cayman Islands, to better understand the localized impacts of aggregation fishing. As part of the Grouper Moon Project, we acoustically tagged ten spawning male Tiger Grouper at the western end of Little Cayman in February 2015. Using an array of hydrophones surrounding the island, we tracked the movements of the ten tagged fish over a 13-month period. We observed 3 migratory strategies: resident fish (n = 2) that live at the FSA site, neighboring fish (n = 5) that live within 4 km of the site, and commuter fish (n = 3) that travel over 4 km for spawning. Fish began aggregating two days before the full moon and typically left between ten and twelve days after the full moon, January through May. Regardless of migratory strategy, all tagged fish that returned to spawn in2015 after the February tagging effort came back to the west-end FSA. However, in January2016, one fish appeared to attend a different FSA closer to its presumed home territory. Unlike other larger-bodied grouper, it appears that Tiger Grouper establish multiple FSAs around Little Cayman, and males attend FSAs near their home territories. Protracted spawning seasons, FSA site infidelity, and putative FSA catchments should all be brought into management consideration to ensure sustainable fisheries for this important species.

Journal of Fish and Wildlife Management https://doi.org/10.3996/JFWM-21-097 \| Abstract	April 2022	Age-structured population models require reliable estimates of cohort-specific survival rates, yet vital rates of younger age classes are often difficult to estimate because of the logistical challenges of monitoring young animals. As part of a study of sandhill cranes <i>Antigone canadensis </i>in the zone of contact between breeding distributions of the Eastern Population and Mid-continent Population in Minnesota, United States, we monitored first summer survival of 34 sandhill cranes (hereafter, “colts”) using VHF and/or GPS-GSM transmitters. We estimated daily survival probabilities from 19 to 120 days post-hatch using a generalized linear model accounting for interval censoring, resulting in an estimated period survival rate of 0.52 (90% confidence interval 0.36–0.71) over summer (100 days). Estimated daily probabilities of survival increased as colts became older and fledged (at 70–75 days post-hatch), when they presumably became less vulnerable to predation. Causes of mortality were mostly unknown aside from one case of a collision with a vehicle. There is a scarcity of published colt survival rate estimates for sandhill cranes and what is available varies widely by study site. Region-specific sandhill crane colt survival rate estimates can inform future management efforts and inform population dynamics research and overall natural history knowledge of sandhill cranes.

Biological Conservation, 261 DOI: 10.1016/j.biocon.2021.109285 \| Abstract	September 2021	Our objective was to understand how social identity and values influenced general public and stakeholder trust in a state wildlife management agency (SWMA). In particular, we wanted to examine how stakeholder group, ideology, and wildlife value orientation influenced trust in a SWMA. Data were derived from a study of state residents, hunters and livestock producers related to wolf management. Results suggest differences in agency trust correlated with all three factors and the interaction between stakeholder group and wildlife value orientation. Livestock producers reported lower levels of trust in the agency, compared to hunters and the general public. Individuals with conservative or middle-of-the-road ideologies reported less trust in the agency than liberals did. Respondents with traditional wildlife values also had less trust in the agency compared to mutualist, pluralist, and distanced respondents. Results suggested parallels in the ideologies and wildlife value orientations of livestock producers and hunters, although these groups differed significantly in their trust in the agency. Agencies face the challenge of managing common-pool resources for stakeholders who hold different values and ideologies, and who are differentially affected by management decisions.

Building on this work, we explored how Minnesota deer hunters coped with the presence of chronic wasting disease (CWD) in the state. Results are based on a survey of 2018 firearm deer hunters. We examined hunters’ reported behavioral intentions in scenarios related to the presence of CWD, and if the disease affected human health. Results suggest that most hunters would cope using product shift (i.e., eating meat after a “CWD not detected” test result) rather than displacement (i.e. hunting elsewhere or not hunting). Hunters who may cope by quitting hunting reported lower levels of involvement and higher levels of concern about CWD. Results have implications for CWD management in the state.

FRONTIERS IN ECOLOGY AND EVOLUTION, 10. \| Abstract	June 2022	Social identity theory offers a means to understand attitudes about wolves, with consequences for management support. Using data from a mail survey about wolves, we explored relationships among seven identities (i.e., wolf advocate, hunter, environmentalist, nature enthusiast, farmer, trapper, conservationist) using multidimensional scaling (MDS) and principal components analysis (PCA). We examined how identities correlated with political orientation, trust in a wildlife management agency, wildlife value orientations (WVOs) and attitudes about wolves, and we evaluated whether WVOs mediated the relationship between identities and attitudes. PCA suggested two factors, while MDS and correlations found diversity beyond these factors. Hunter identity was most strongly associated with a domination WVO and conservative political ideology. Farmer identity was most strongly associated with agency distrust and negative wolf attitudes. Wolf advocate was most strongly associated with a mutualism WVO, agency trust, and positive wolf attitudes. Conservationist identity was positively correlated with all other identities. WVOs partially mediated the relationship between identities and attitudes.

Wetlands 44, 35 (2024). https://doi.org/10.1007/s13157-023-01744-w \| Abstract	February 2024	Canadian and American waterfowl hunters were surveyed to identify their hunting trip preferences. Respondents were individuals that were or had participated in waterfowl hunting, and most had hunted the majority of the last five years. We identified four latent classes of waterfowl hunters that varied in their preferences for harvest, access effort, length of travel, quantity of waterfowl seen, and the potential for interference/ competition. We found a diminishing return associated with the number of waterfowl harvested, and that devoted and local hunters did not perceive appreciable benefit from harvesting more birds beyond harvesting a single bird. Results highlight the importance of not only considering population size, but also the location of habitat for people and waterfowl. Our results provide waterfowl managers important insights into the heterogeneity of North American waterfowl hunters by highlighting differences in priorities for waterfowl hunting trips. Notably, to address this heterogeneity, managers could consider the balance of objectives, actions and resources designed to satisfy current waterfowl hunters to that of attracting new individuals. Managing access to improve the likelihood that hunters will see and have opportunities to harvest some waterfowl has benefit to hunters.

Large-scale projects such as eBird have produced data that have advanced science and contributed to many conservation applications. These projects also provide a means to engage the public in scientific data collection. A common challenge across contributory projects like eBird is to maintain participation, as some volunteers contribute just a few times before disengaging. To maximize contributions and manage an effective program that has broad appeal, it is useful to better understand factors that influence contribution rates. For projects capitalizing on recreation activities (e.g., birding), differences in contribution levels might be explained by the recreation specialization framework, which describes how recreationists vary in skill, behavior, and motives. We paired data from a survey of birders across the United States and Canada with data on their eBird contributions (<i>n</i> = 28,926) to test whether those who contributed most are more specialized birders. We assigned participants to 4 contribution groups based on eBird checklist submissions and compared groups’ specialization levels and motivations. More active contribution groups had higher specialization, yet some specialized birders were not active participants. The most distinguishing feature among groups was the behavioral dimension of specialization, with active eBird participants owning specialized equipment and taking frequent trips away from home to bird. Active participants had the strongest achievement motivations for birding (e.g., keeping a life list), whereas all groups had strong appreciation motivations (e.g., enjoying the sights and sounds of birding). Using recreation specialization to characterize eBird participants can help explain why some do not regularly contribute data. Project managers may be able to promote participation, particularly by those who are specialized but not contributing, by appealing to a broader suite of motivations that includes both appreciation and achievement motivations, and thereby increase data for conservation.

PMID: 34847304. \| Abstract \| Publisher Website	October 2021	Critically ill patients needing mechanical ventilation may require hyperbaric oxygen therapy. Some institutions still use ventilators that were available prior to the advent of hyperbaric-specific units, such as the Uni-Vent Eagle™ Model model 754. Here we examine the performance of the Uni-Vent model 754 under hyperbaric conditions and investigate concerns of an oxygen leak in the ventilator housing, which poses a fire risk. We studied the ventilator at 1.0, 2.4 and 2.8 ATA in assist control mode using a Michigan test lung and a variety of tidal volumes and respiratory rates. We recorded the delivered volumes, peak pressures, and oxygen percentages within the hyperbaric chamber at 2.4 and 2.8 ATA and within the ventilator housing. At those pressures the ventilator delivered approximately 25% less volume than at 1.0 ATA. We observed breath stacking at high respiratory rates, but this was blunted at both 2.4 and 2.8 ATA. Oxygen levels did not rise in the housing during our investigation. In addition, we fit a linear regression to the data comparing set tidal volumes and delivered tidal volumes in order to model the changes observed. Hyperbaric conditions caused decreased delivered tidal volumes in a depth-dependent fashion, and oxygen levels within the housing did not rise. The Uni-Vent Eagle model 754 performed safely and effectively at depth but requires spirometry to correctly program desired ventilator settings.

DOI: https://doi.org/10.3354/meps13912 \| Abstract \| Publisher Website	January 2022	Sound production rates of fishes can be used as an indicator for coral reef health, providing an opportunity to utilize long-term acoustic recordings to assess environmental change. As acoustic datasets become more common, computational techniques need to be developed to facilitate analysis of the massive data files produced by long-term monitoring. Machine learning techniques demonstrate an advantage in the identification of fish sounds over manual sampling approaches. Here we evaluate the ability of convolutional neural networks to identify and monitor call patterns for pomacentrids (damselfishes) in a tropical reef region of the western Pacific. A stationary hydrophone was deployed for 39 months(2014-2018) in the National Park of American Samoa to continuously record the local marine acoustic environment. A neural network was trained—achieving 94%identification accuracy of pomacentrids—to demonstrate the applicability of machine learning in fish acoustics and ecology. The distribution of sound production was found to vary on diel and interannual timescales. Additionally, the distribution of sound production was correlated with wind speed, water temperature, tidal amplitude, and sound pressure level. This research has broad implications for state--of--the--art acoustic analysis and promises to be an efficient, scalable asset for ecological research, environmental monitoring and conservation planning.

Journal of Wildlife Management 83:1617–1627. DOI:10.1002/jwmg.21741. \| Abstract	August 2019	As with many migratory birds, migratory connectivity of American woodcock (Scolopax minor; hereafter, woodcock) is largely unknown. Understanding migratory connectivity and migration phenology is important in identifying factors that influence survival and fitness over the full annual cycle. However, until recently, practical methods (i.e., data derived from banding and VHF telemetry) for elucidating migratory connectivity and migration phenology of woodcock have provided relatively coarse-resolution delineation of migration patterns. Based largely on analysis of band returns, woodcock are managed in 2 management regions (Eastern and Central Management Regions) with management region boundaries analogous to those of the Atlantic and Mississippi Flyways. To better understand woodcock migration and evaluate the validity of current management regions, we deployed satellite transmitters on 73 woodcock in the Central Management Region, and from 2014-2016 documented migration paths of 60 individual woodcock and 87 autumn or spring woodcock migrations. Marked woodcock captured in the Central Management Region used 2 primary migrations routes: a Western Route and a Central Route. The Western Route ran north-south, connecting the breeding and wintering grounds within the Central Management Region. The hourglass-shaped Central Route connected an area on the wintering grounds reaching from Texas to Florida, to sites throughout northeastern North America in the Eastern Management Region and Central Management Region. Woodcock following the Central Route migrated through the area between the Appalachian Mountains and the Mississippi Alluvial Valley in western Tennessee during both autumn and spring. A higher than anticipated (based on previous banding data analyses) percentage (36%, n = 12) of marked woodcock captured in Texas and Louisiana and monitored during spring migration migrated to breeding-period sites in the Eastern Management Region, raising questions about the biological relevance of managing woodcock in separate management regions.

DOI:10.24926/AWS.0124. \| Abstract \| Download	December 2019	The American woodcock (Scolopax minor) Singing-Ground Survey (SGS) was developed to inform management decisions by monitoring changes in the relative abundance of woodcock. The timing of the designated survey windows were designed to count woodcock that have settled in an area while minimizing the counting of migrating woodcock to the best extent possible. Since the implementation of the SGS in 1968, concerns over survey protocols that may bias data have been raised and investigated; however, the extent of survey coverage , the timing of the survey window zones, and whether double counting might occur within and among survey zones have not been critically investigated We used three years of data collected from satellite-marked male and female woodcock to assess the timing of the SGS survey windows and to what extent there was potential to double count woodcock among the survey zones. SGS coverage encompassed the majority of woodcock breeding-period sites within the U.S. (n = 17, 92%) and approximately half of the breeding period sites in Canada (n = 6, 43%). Thirteen of the 37 monitored woodcock with known breeding-period site arrival dates (35%) were migrating through a survey zone during an active survey window, all in the northernmost four out of five SGS zones. Thirteen woodcock arrived at breeding period sites after the start of surveys, all but one with breeding-period sites in the northernmost two zones. The combination of these situations may result in the SGS weighing too heavily the contribution of routes in southern portion of the primary breeding range while weighing too lightly the routes in the northern portion of the primary breeding range. We believe that we have demonstrated enough concerns about zone window timing to suggest that additional information is necessary to evaluate whether current zone window dates are sufficient, or whether they need to be changed.

Journal of Hydrological Processes 25: 593-602. \| Abstract	January 2011	Wood deposited in streams provides a wide variety of ecosystem functions, including enhancing habitat for key species in stream food webs, increasing geomorphic and hydraulic heterogeneity, and retaining organic matter. Given the role that wood plays in streams, factors that influence wood inputs, retention, and transport are critical to stream ecology. Wood entrapment, the process of wood coming to rest after being swept downstream at least 10 m, is poorly understood yet important for predicting stream function and success of restoration efforts. Data on entrapment were collected for a wide range of natural wood pieces (n = 344), stream geomorphology, and hydraulic conditions in nine streams along the shore of Lake Superior in Minnesota. Locations of pieces were determined in summer 2007 and again following an overbank event in fall 2007. The ratio of piece length to effective stream width (length ratio) and the weight of the pieces were important in a multiple logistic regression model that explained 25% of the variance in wood entrapment. Entrapment remains difficult to predict in natural streams, and often may simply occur wherever wood pieces are located when high water recedes. However, this study can inform stream modifications to discourage entrapment at road crossings or other infrastructure by determining the effective stream width required to pass particular wood pieces. Conversely, these results could also be used to determine conditions that encourage entrapment where wood is valued for ecological functions.

Water Resources Research 46: W10514. \| Abstract	October 2010	Natural pieces of wood provide a variety of ecosystem functions in streams, including habitat, organic matter retention, increased hyporheic exchange and transient storage, and enhanced hydraulic and geomorphic heterogeneity. Wood mobilization is a critical process in determining the residence time of wood. We documented the characteristics and locations of 865 natural wood pieces ( > 0.05 m in diameter for a portion > 1 m in length) in nine streams along the north shore of Lake Superior in Minnesota. We determined the locations of the pieces again after an overbank stormflow event to determine the factors that influenced mobilization of stationary wood pieces in natural streams. Seven of 11 potential predictor variables were identified with multiple logistic regression as significant to mobilization: burial, effective depth, ratio of piece length to effective stream width (length ratio), bracing, rootwad presence, downstream force ratio, and draft ratio. The final model (p < 0.001, r2 = 0.39) indicated that wood mobilization under natural conditions is a complex function of both mechanical factors (burial, length ratio, bracing, rootwad presence, draft ratio) and hydraulic factors (effective depth, downstream force ratio). If stable pieces are a goal for stream management then features such as partial burial, low effective depth, high length relative to channel width, bracing against other objects (e.g., stream banks, trees, rocks, or larger wood pieces), and rootwads are desirable. Using the model equation from this study, stewards of natural resources can better manage instream wood for the benefit of stream ecosystems.

Journal of the American Water Resources Association 46(4):733-743. \| Abstract	August 2010	We investigated the recovery of sediment characteristics in four moraine, headwater streams in north-central Minnesota after forest harvest. We examined changes in fine sediment levels from 1997 (preharvest) to 2007 (10 years postharvest) at study plots with upland clear felling and riparian thinning, using canopy cover, proportion of unstable banks, surficial fine substrates, residual pool depth, and streambed depth of refusal as response variables. Basin-scale year effects were significant (p < 0.001) for all responses when evaluated by repeated-measures ANOVAs. Throughout the study area, unstable banks increased for several years postharvest, coinciding with an increase in windthrow and fine sediment. Increased unstable banks may have been caused by forest harvest equipment, increased windthrow and exposure of rootwads, or increased discharge and bank scour. Fine sediment in the channels did not recover by summer 2007, even though canopy cover and unstable banks had returned to 1997 levels. After several storm events in fall 2007, 10 years after the initial sediment input, fine sediment was flushed from the channels and returned to 1997 levels. Although our study design did not discern the source of the initial sediment inputs (e.g., forest harvest, road crossings, other natural causes), we have shown that moraine, headwater streams can require an extended period (up to 10 years) and enabling event (e.g., high storm flows) to recover from large inputs of fine sediment.

North American Journal of Fisheries Management 42 (2), 295-306 \| Abstract	March 2022	The release of live baitfish by anglers has been identified as a high-risk pathway for aquatic invasive species due to the potential for invasive fish, invertebrates, or pathogens to be released simultaneously with the baitfish. Consequently, the release of live baitfish is illegal in many jurisdictions, but little is known about compliance rates or motivations for illegal release. To assess the incidence of live baitfish release in Minnesota, USA, a state with significant live baitfish use and substantial recreational fisheries, we administered a mailed survey to a random sample of anglers who held a 2018-2019 annual fishing license and received 671 completed responses. To mitigate potential recall bias, we also administered 345 intercept surveys at waterbody access sites around the state asking anglers about the current day’s behaviors. Four hundred and eighty-one (72%) of the mailed survey respondents reported that they used live baitfish and of those, 99 (20%) reported that they release their leftover live baitfish into the water at least some of the time. Of the anglers surveyed at waterbody access sites, 59 (19%) were using live baitfish on the day they were surveyed and of those, 11 (18%) released their leftover baitfish into the water. The reasons provided for release included convenience and a misperception that released baitfish benefit the recipient ecosystem. Given the millions of fishing trips that occur every year, the current rate of baitfish release results in many chances for invasive species introduction. However, there is also significant opportunity for management interventions aimed at changing perceptions and providing convenient disposal alternatives to illegal release to reduce the risk presented by this pathway.

Lake and Reservoir Management 29 (3):179–193. \| Abstract	August 2013	Aquatic habitat in littoral environments can be affected by residential development of shoreline areas. We evaluated the relationship between macrophyte richness metrics and shoreline development to quantify indicator response at two spatial scales for Minnesota lakes. First, the response of total, submersed, and sensitive species to shoreline development was evaluated within lakes to quantify macrophyte response as a function of distance to the nearest dock. Within-lake analyses using Generalized Linear Mixed Models focused on three lakes of comparable size and minimal influence of watershed land use. Survey points farther from docks had higher total species richness and presence of species sensitive to disturbance. Second, between-lake effects of shoreline development on total, submersed, emergent-floating, and sensitive species were evaluated for a set of 1444 lakes. Generalized Linear Models were developed for all lakes and stratified subsets to control for lake depth and watershed land use. Between-lake analyses illustrated clear response of macrophyte richness metrics to increasing shoreline development, such that fewer emergent-floating and sensitive species were correlated with increasing density of docks. These trends were particularly evident for deeper lakes with lower watershed development. The results provide further evidence that shoreline development is associated with degraded aquatic habitat, particularly by illustrating the response of macrophyte richness metrics across multiple lake types and different spatial scales.

ISPRS Journal of Photogrammetry and Remote Sensing 81:60–69. \| Abstract	May 2013	Lake resources can be negatively affected by environmental stressors originating from multiple sources and different spatial scales. Shoreline development, in particular, can negatively affect lake resources through decline in habitat quality, physical disturbance, and impacts on fisheries. The development of remote sensing techniques that efficiently characterize shoreline development in a regional context could greatly improve management approaches for protecting and restoring lake resources. The goal of this study was to develop an approach using high-resolution aerial photographs to quantify and assess docks as indicators of shoreline development. First, we describe a dock analysis workflow that can be used to quantify the spatial extent of docks using aerial images. Our approach incorporates pixel-based classifiers with object-based techniques to effectively analyze high-resolution digital imagery. Second, we apply the analysis workflow to quantify docks for 4,261 lakes managed by the Minnesota Department of Natural Resources. Overall accuracy of the analysis results was 98:4% (87:7% based on ˆK ) after manual post-processing. The analysis workflow was also 74% more ecient than the time required for manual digitization of docks. These analyses have immediate relevance for resource planning in Minnesota, whereas the dock analysis workflow could be used to quantify shoreline development in other regions of the Upper Midwest United States. These data can also be used to better understand the effects of shoreline development on aquatic resources and to evaluate the eects of shoreline development relative to other stressors.

Published online May 26, 2022 https://doi.org/10.1080/10871209.2022.2077480 \| Abstract	May 2022	Hunters in the United States are motivated to obtain and benefit from diverse experiences or experience preferences. Using a mail survey conducted during the 2015–2016 hunting season, we examined goal-oriented, introspective, and leadership experiences among hunters on Minnesota Department of Natural Resources’ Wildlife Management Area (WMAs). We used k-means cluster analysis to identify six clusters based on experience preferences. We defined these clusters using their ranked experience preferences and segregated them into categories of either participants or enthusiasts. These clusters showed differences in demographic characteristics, as well as support for management actions on WMAs. Hunters in clusters with lower importance ratings of experience preferences also reported less attachment to WMAs. High levels of support for management actions were closely related to high levels of place attachment. Using information gained from describing the heterogeneity of desired experiences, managers may be better able to understand their constituents and prioritize management goals to provide a variety of hunting experiences.

Journal of the American Water Resources Association 49(4):896-907. \| Abstract	April 2013	Carbonate - sandstone geology in southeastern Minnesota creates a heterogeneous landscape of springs, seeps, and sinkholes that supply groundwater into streams. Air temperatures are effective predictors of water temperature in surface - water dominated streams. However, no published work investigates the relationship between air and water temperatures in groundwater - fed streams across watersheds. We used simple linear regressions to examine weekly air - water temperature relationships for 40 groundwater - fed streams in southeastern Minnesota. A 40 - stream, composite linear regression model has a slope of 0.38, an intercept of 6.63, and R2 of 0.83. The regression models for groundwater - fed streams have lower slopes and higher intercepts in comparison to surface - water dominated streams. Regression models for streams with high R2 values offer promise for use as predictive tools for future climate conditions. Climate change is expected to alter the thermal regime of groundwater - fed systems, but will do so at a slower rate than surface - water dominated systems. A regression model of intercept vs. slope can be used to identify streams for which water temperatures are more meteorologically than groundwater controlled, and thus more vulnerable to climate change. Such relationships can be used to guide restoration versus management strategies to protect trout streams.

Anthropause shows differential influence of tourism and a no-take reserve on the abundance and size of two fished species. Aquatic Conservation: Marine and Freshwater Ecosystems 1– 17. https://doi.org/10.1002/aqc.3856 \| Abstract	December 2022	1. Marine reserves are essential spatial conservation tools that have been shown to work alongside fishery management strategies to provide benefits to ecosystems and communities. Reserves often incentivize local tourism, which can provide the impetus for reserve creation but may have negative impacts on the ecosystem.<br>2. The COVID-19 pandemic paused global travel and provided an unprecedented opportunity to compare short-term changes in exploited populations, during the reprieve from visitation provided by this ‘anthropause’, with the results of long-term conservation management.<br>3. Repeated surveys of Caribbean spiny lobster and Nassau grouper were conducted at popular dive and snorkel locations within a Bahamian no-take reserve and surrounding areas during peak visitation prior to travel restrictions and immediately after restrictions were lifted. Repeated survey results were referenced against surveys over a broader area, including another Bahamian Bank, to examine the consistency of effects and how the ease of access for fishers impacted abundance.<br>4. In the reserve, lobsters were encountered in significantly greater abundances, and significantly greater sizes of both lobster and grouper were observed in repeated surveys. Significantly more grouper were encountered during the repeated survey within the reserve after travel restrictions, but lobster abundances did not change significantly.<br>5. Over a broader scale, lobster abundance was significantly greater further from population centres. Observed lobster abundance was affected by habitat and inferred fishing pressure, whereas observed grouper abundance was affected by survey depth, effort, and habitat.<br>6. Marine reserves had clear benefits for both species and likely facilitated an increase in grouper abundance during the anthropause. Lobsters are a sustainably managed stock in The Bahamas, whereas grouper are a threatened species that appear to have benefited from an unplanned fishery restriction. Well-managed marine reserves enhance populations long term and can have additive effects with fisheries management over short timescales.

Conservation Genetics DOI 10.1007/s10592-010-0124-6. \| Abstract	December 2010	Reintroductions are a common approach for preserving intraspecific biodiversity in fragmented landscapes. However, they may exacerbate the reduction in genetic diversity initially caused by population fragmentation because the effective population size of reintroduced populations is often smaller and reintroduced populations also tend to be more geographically isolated than native populations. Mixing genetically divergent sources for reintroduction purposes is a practice intended to increase genetic diversity. We documented the outcome of reintroductions from three mixed sources on the ancestral composition and genetic variation of a North American fish, the slimy sculpin (Cottus cognatus). We used microsatellite markers to evaluate allelic richness and heterozygosity in the reintroduced populations relative to computer simulated expectations. Sculpins in reintroduced populations exhibited higher levels of heterozygosity and allelic richness than any single source, but only slightly higher than the single most genetically diverse source population. Simulations intended to mimic an ideal scenario for maximizing genetic variation in the reintroduced populations also predicted increases, but they were only moderately greater than the most variable source population. We found that a single source contributed more than the other two sources at most reintroduction sites. We urge caution when choosing whether to mix source populations in reintroduction programs. Genetic characteristics of candidate source populations should be evaluated prior to reintroduction if feasible. When combined with knowledge of the degree of genetic distinction among sources, simulations may allow the genetic diversity benefits of mixing populations to be weighed against the risks of outbreeding depression in reintroduced and nearby populations.

Molecular Ecology 20:4246–4258. \| Abstract	October 2011	Reintroductions are commonly employed to preserve intraspecific biodiversity in fragmented landscapes. However, reintroduced populations are frequently smaller and more geographically isolated than native populations. Mixing genetically, divergent sources are often proposed to attenuate potentially low genetic diversity in reintroduced populations that may result from small effective population sizes. However, a possible negative tradeoff for mixing sources is outbreeding depression in hybrid offspring. We examined the consequences of mixed-source reintroductions on several fitness surrogates at nine slimy sculpin (Cottus cognatus) reintroduction sites in south-east Minnesota. We inferred the relative fitness of each crosstype in the reintroduced populations by comparing their growth rate, length, weight, body condition and persistence in reintroduced populations. Pure strain descendents from a single source population persisted in a greater proportion than expected in the reintroduced populations, whereas all other crosstypes occurred in a lesser proportion. Length, weight and growth rate were lower for second-generation intra-population hybrid descendents than for pure strain and first-generation hybrids. In the predominant pure strain, young-of the-year size was significantly greater than any other crosstype. Our results suggested that differences in fitness surrogates among crosstypes were consistent with disrupted co-adapted gene complexes associated with beneficial adaptations in these reintroduced populations. Future reintroductions may be improved by evaluating the potential for local adaptation in source populations or by avoiding the use of mixed sources by default when information on local adaptations or other genetic characteristics is lacking.

Testing a continuous measure of recreation specialization among birdwatchers, Human Dimensions of Wildlife. https://doi.org/10.1080/10871209.2020.1843741 \| Abstract	November 2020	Recreation specialization is a framework that can be used to explain the variation among recreationists’ preferences, attitudes, and behaviors. Recreation specialization has been operationalized using several approaches, including summative indices, cluster analysis, and self-classification categorical measures. While these approaches have their benefits, there remains a need for a continuous (interval) measure of recreation specialization that reflects the influence of the different dimensions of the framework by accounting for individual variation among the dimensions. This research note illustrates an approach that uses second-order confirmatory factor analysis (CFA) factor scores as weights to determine a person’s degree of recreation specialization and compares the CFA-based results to a cluster analysis approach. Data were collected from an online survey of eBird registrants from the United States. This CFA approach provides increased consistency in the operationalization and application of recreation specialization.

Wildlife Society Bulletin 48:e1505. https://doi.org/10.1002/wsb.1505 \| Abstract	January 2024	Due to the steady decline of duck hunter participation, several studies have investigated means to bolster the duck hunter population. Researchers and wildlife professionals have assumed that simpler regulations would attract new and unconfident hunters to participate in duck hunting. In light of this, we sought to identify what portion of the duck-hunting population had difficulty understanding species-specific bag limits or complying with species-specific bag limits in the field. We also sought to describe hunters who had difficulty complying with specific bag limits and how their difficulties were associated with elements related to demography, attitude, and behavior. We found most hunters had no difficulty understanding or complying with species specific bag limits, but flyway, number of ducks harvested, and number of years hunted were important to predicting hunter difficulty with compliance. Hunters who can overcome their difficulties understanding and complying with species-specific bag limits may be more likely to be integrated into the duck hunting culture, and ultimately more likely to continue duck hunting in the future. More species identification tools and fewer species-specific bag limits may be appropriate for the 18% of the duck hunter population who indicated that bag-specific regulations were difficult to understand and the 26% who indicated that it was difficult to comply with species-specific bag limits in the field. A closer look at how the trade-offs associated with the combination of species-specific bag limits in combination with the variety of duck season zone and split options states employ, license/stamp requirements, area-specific regulations, and trespass laws may influence duck hunter experiences may be warranted.<br><b>KEYWORDS </b>attitude, behavior, demographics, human dimensions, hunting constraints, waterfowl hunting.

Environment Systems and Decisions 40:577-587. DOI: 10.1007/s10669-020-09766-z \| Abstract	March 2020	Due to extensive land conversion over the last century, much of the native prairie pothole ecosystem has been converted to agricultural or other human uses. The prairie pothole ecosystem is found in the northern plains of Iowa, Minnesota, South Dakota, North Dakota, and Montana. Because most of the land in this region is privately owned and used for agricultural production, most impacts to wildlife habitat are the result of decisions by individual landowners. Landowner trust in natural resource management agencies is important for agencies to effectively accomplish their mission. We measured the nature (competence and fairness) and level of trust that western Minnesota landowners have in the Minnesota Department of Natural Resources (MnDNR) and landowners’ wildlife value orientations (WVO). Landowners rated MnDNR slightly higher in competence than fairness; however, these two dimensions were strongly correlated. We developed a MnDNR trust scale (six items) and a three-cluster model dividing landowners along the MnDNR trust scale, which we named Negative (28%), Neutral (43%), and Positive (29%). We provide evidence supporting the salient values similarity (SVS) model that states people have trust in agencies holding similar values; landowners reporting greater importance for wildlife consideration when making land-use decisions also reported greater trust in the MnDNR. In addition, mutualist landowners had the highest trust in the MnDNR and utilitarian landowners the lowest level of trust, which is opposite of the trust relationship reported for the general public with state wildlife agencies. Based on the SVS model, our results suggest that mutualist landowners perceive greater congruence with MnDNR goals related to wildlife habitat compared to utilitarian landowners.

To be submitted to Fisheries Management and Ecology \| Abstract	May 2014	Winter can be a stressful period for stream trout populations. Groundwater may moderate water temperature and reduce the negative impacts of winter but few studies have examined food webs supporting trout under winter conditions. We used diet, stable isotope analysis, and mark-recapture to examine winter feeding, growth, and condition of brown trout Salmo trutta in a groundwater-dominated stream. Growth occurred during the winter season and was greater for fish < 150mm (mean = 4.1 mg/g/day) than for those 151 - 276mm (mean = 1.0 mg/g/day). Overall condition from early winter to late winter did not vary for fish < 150mm (Mean Wr = 89.5) and increased for those 151 - 276mm (Mean Wr = 85.8 early, 89.4 late). Although composition varied both temporally and by individual, brown trout diets were dominated by aquatic invertebrates; primarily Isopods, Dipterans, and Trichopterans. Stable isotope analysis supported the observations of dominant prey taxa observed in stomach contents, and suggested trout may have used a combination of allochthonous- and autochthonous-derived resources. We found that trout likely benefited from the thermal regime and increased prey abundance present in this groundwater-dominated stream during winter.

Freshwater Biology 56(8):1652-1699. \| Abstract	July 2011	1. Fish and invertebrate assemblage data collected from 670 stream sites in Minnesota (USA) were used to calculate concordance across three nested spatial scales (statewide, ecoregion and catchment). Predictive taxa richness models, calibrated using the same data, were used to evaluate whether concordant communities exhibited similar trends in human-induced taxa loss across all three scales. Finally, we evaluated the strength of the relationship between selected environmental variables and the composition of both assemblages at all three spatial scales. 2. Significant concordance between fish and invertebrate communities occurred at the statewide scale as well as in six of seven ecoregions and 17 of the 21 major catchments. However, concordance was not consistently indicative of significant relationships between rates of fish and invertebrate taxa loss at those same scales. 3. Fish and invertebrate communities were largely associated with different environmental variables, although the composition of both communities was strongly correlated to stream size across all three scales. 4. Predictive taxa-loss models for fish assemblages were less sensitive and precise than models for invertebrate assemblages, likely because of the relatively low number of common fish taxa in our dataset. Both models, however, distinguished reference from non-reference sites. 5. The importance of concordance, geographic context and scale are discussed in relation to the design and interpretation of stream integrity indicators. In particular, our findings suggest that community concordance should not be viewed as a substitute for an evaluation of how assemblages respond to environmental stressors.

Past patch quality as a predictor of future habitat selection: relating movement behavior of American woodcock to environmental factors. Wildlife Biology 16:379-388. \| Abstract \| Publisher Website	December 2010	Quality of recently used foraging areas is likely an important predictor of fidelity to specific locations in the future. We monitored movement and habitat use of 58 adult female American woodcock Scolopax minor at three study areas in Minnesota, Wisconsin and Michigan, USA, during autumn 2002 and 2003, to assess the relationship between foraging habitat use decisions and environmental conditions at previously used foraging locations. We assessed whether habitat variables which related to food and weather were related to distance between locations on subsequent days of individual woodcock that choose diurnal foraging locations when they return from night-time roosting locations. We predicted that woodcock would return to foraging locations used on the previous day (i.e. shorter distances between daily foraging locations) when environmental conditions on the prior day were favourable. Woodcock generally made short (i.e. 48%,50mand 91%,400 m) between-day movements, but also occasionally (;7%) abandoned prior foraging areas. The primary determinants of woodcock movements during autumn (prior to migration) were low local food availability and potential for increased food availability elsewhere. The quality of foraging locations was an important predictor of future foraging habitat use for woodcock, consistent with the hypothesis that woodcock movement behaviour balances the risks associated with movement with the potential benefits of increased energy intake in new foraging areas.

The influence of partial timber harvesting in riparian buffers on macroinvertebrate and fish communities in small streams in Minnesota, USA. Forest Ecology and Management 259(10):1946-1958. \| Abstract	April 2010	Relatively few evaluations of aquatic macroinvertebrate and fish communities have been published in peer-reviewed literature detailing the effect of varying residual basal area (RBA) after timber harvesting in riparian buffers. Our analysis investigated the effects of partial harvesting within riparian buffers on aquatic macroinvertebrate and fish communities in small streams from two experiments in northern Minnesota northern hardwood-aspen forests. Each experiment evaluated partial harvesting within riparian buffers. In both experiments, benthic macroinvertebrates and fish were collected 1 year prior to harvest and in each of 3 years after harvest. We observed interannual variation for the macroinvertebrate abundance, diversity and taxon richness in the single-basin study and abundance and diversity in the multiple-basin study, but few effects related to harvest treatments in either study. However, interannual variation was not evident in the fish communities and we detected no significant changes in the stream fish communities associated with partially harvested riparian buffers in either study. This would suggest that timber harvesting in riparian management zones along reaches ≤200m in length on both sides of the stream that retains RBA≥12.4±1.3m2 ha−1 or on a single side of the stream that retains RBA≥8.7±1.6m2 ha−1 may be adequate to protect macroinvertebrate and fish communities in our Minnesota study systems given these specific timber harvesting techniques.

Forest Ecology and Management 261(11):1892-1900. \| Abstract	July 2011	We compared avian communities among three timber harvesting treatments in 45-m wide riparian management zones (RMZs) placed between upland clearcuts and along one side of first- or second-order streams in northern Minnesota, USA. The RMZs had three treatments: 1) unharvested, 2) intermediate residual basal area (RBA) (targeted goal 11.5 m2/ha, realized 16.0 m2/ha), and 3) low RBA (targeted goal 5.7 m2/ha, realized 8.7 m2/ha). Surveys were conducted one year pre-harvest and three years post-harvest. There was no change in species richness, diversity, or total abundance associated with harvest but there were shifts in the types of birds within the community. In particular, White-throated Sparrows (Zonotrichia albicollis) and Chestnut-sided Warblers (Dendroica pensylvanica) increased while Ovenbirds (Seiurus aurocapilla) and Red-eyed Vireos (Vireo olivaceus) decreased. The decline of avian species associated mature forest in the partially harvested treatments relative to controls indicates that maintaining an unharvested RMZ adjacent to an upland harvest may aid in maintaining avian species associated mature forest in Minnesota. However, our observations do not reflect reproductive success, which is an area for future research.
Carlson, A. K., and B. Vondracek. Predictive Management of Asian Carps in the Upper Mississippi River System. Reviews in Fish Biology and Fisheries. \| Abstract	December 2014	Nonnative bighead carp (Hypophthalmichthys nobilis) and silver carp (H. molitrix), collectively referred to as Asian carps, are poised to colonize aquatic ecosystems throughout the central United States. These species are r-selected, exhibiting iteroparous spawning early in life, short generation time, rapid growth, broad environmental tolerance, high density, and wide dispersal. Hydrological, thermal, and physicochemical conditions are favorable for establishment beyond the current range, rendering containment and control imperative. Contemporary Asian carp management in the United States aims to confine populations and prevent colonization. Foraging and reproduction of Asian carps govern habitat selection and movement, providing valuable insight for predictive control. Current management approaches are progressive and often anticipatory but sociologically deficient. We define predictive management of Asian carps as synthesis of ecology and human dimensions at regional and local scales to develop strategies for containment and control. We illustrate predictive management in the Upper Mississippi River System and suggest resource managers integrate predictive models, containment paradigms, and human dimensions to design effective, socially acceptable management strategies. As Asian carps knock on the proverbial door, predictive management is an auspicious paradigm for preventing and alleviating consequences of colonization in the United States.

Brand, G., B. Vondracek, and N. R. Jordan. Influence of grazing and land use on stream channel characteristics at multiple scales. \| Abstract	October 2014	Rotational grazing (RG) is a livestock management practice that rotates cattle on a scale of hours to days among small pastures called paddocks; RG may provide beneficial effects on stream channels relative to other livestock management practices, but previous comparisons have been restricted in scale and scope. We evaluated 11 stream channel characteristics on 37 small dairy farms that used either RG or confinement dairy (CD) production methods. Our objectives were to: (1) compare channel characteristics on RG and CD farms in New York, Pennsylvania, and Wisconsin, USA; (2) examine land use on and around these farms that may affect stream channel characteristics. We examined on-farm land use in 50m riparian areas along selected stream reaches, whole-farm land use, and land use in catchments upstream of selected reaches. RG and CD farms did not differ broadly in stream channel characteristics, although modest differences occurred in some areas. Land cover in 50m riparian areas was not different between farm types within states. As expected, whole-farm land use differed significantly between farm types; CD farms allocated more land to annual row crops, whereas RG farms allocated more land to pasture and grassland. Land cover in catchments was not significantly different, demonstrating that the landscape context of RG and CD farms was similar. Our finding that RG farms did not have substantial beneficial effects on stream channel characteristics compared to CD farms accords with a broader comparison of environmental attributes on these study farms, which found only limited beneficial effects of RG on grassland bird abundance and native plant conservation. The biophysical attributes of stream channels differed across study regions. We suggest catchment-wide implementation of RG dairy farming will be needed to achieve substantial improvement in stream channel characteristics from this livestock management practice.

Beck, M. W., L. K. Hatch, B. Vondracek, and R. D. Valley. 2010. Development of a macrophyte-based index of biotic integrity for Minnesota lakes. Ecological Indicators 10:968–979. \| Abstract	April 2010	Traditional approaches for managing aquatic resources have often failed to account for effects of anthropogenic disturbances on biota that are not directly reflected by chemical and physical proxies of environmental condition. The index of biotic integrity (IBI) is a potentially effective assessment method to integrate ecological, functional, and structural aspects of aquatic systems. A macrophyte-based IBI was developed for Minnesota lakes to assess the ability of aquatic plant communities to indicate environmental condition. The index was developed using quantitative point intercept vegetation surveys for 97 lakes that represent a range of limnological and watershed characteristics. We followed an approach similar to that used in Wisconsin to develop the aquatic macrophyte community index (AMCI). Regional adaptation of the AMCI required the identification of species representative of macrophyte communities in Minnesota. Metrics and scaling methods were also substantially modified to produce a more empirically robust index. Regression analyses indicated that IBI scores reflected statewide differences in lake trophic state (R2 = 0.57, F = 130.3, df = 1, 95, p < 0.005), agricultural (R2 = 0.51, F = 83.0, df = 1, 79, p < 0.005), urban (R2 = 0.22, F = 23.0, df = 1, 79, p < 0.005), and forested land uses (R2 = 0.51, F = 84.7, df = 1, 79, p < 0.005), and county population density (R2 = 0.14, F = 16.6, df = 1, 95, p < 0.005). Variance partitioning analyses using multiple regression models indicated a unique response of the IBI to human-induced stress separate from a response to natural lake characteristics. The IBI was minimally affected by differences in sample point density as indicated by Monte Carlo analyses of reduced sampling effort. Our analysis indicates that a macrophyte IBI calibrated for Minnesota lakes could be useful for identifying differences in environmental condition attributed to human-induced stress gradients.

Aquatic Botany 108:16–25. \| Abstract	July 2013	A primary objective of biological assessment (bioassessment) is to determine the condition of living organisms using their response to environmental changes. Accurate bioassessment requires practitioners to determine the proportions of biological response attributed to natural variation and human-induced degradation. The absence of approaches for defining comparable groups of aquatic systems that are expected to have similar communities in the absence of anthropogenic stressors can prevent the extraction of useful information from biological surveys. The macrophyte-based index of biotic integrity was developed to assess the condition of Minnesota lakes but also exhibits responses to both environmental and anthropogenic variables. The objectives of the current study were to determine the explicit effects environmental factors have on macrophyte index response and to determine if the existing scoring criteria are adequate for accurate bioassessment. A comprehensive set of environmental variables was evaluated and used in a multivariate framework to identify comparable groups of lakes. Variance partitioning analyses were used to identify the fractions of variation of macrophyte response that could be attributed to environmental and/or anthropogenic variables. We found that lakes could be grouped by ecoregion, but these groups did not fully account for the variation in macrophyte communities. Additionally, a majority of the biological response could not be differentiated between environmental and anthropogenic variables due to substantial correlations among the explanatory variables. However, IBI scores exhibited stronger signals to anthropogenic variables than the component metrics, suggesting the index has potential for accurate bioassessment provided comparable groups of lakes are identified. Relevant variables to consider for improving biological assessment and additional approaches for further validation of the index are suggested. Although this information is applicable to Minnesota, this approach is relevant for any agency concerned with accurate bioassessment.

(Accepted by Environmental Monitoring and Assessment, posted in Online First) http://www.springerlink.com/content/26r16724382t542n/fulltext.pdf) \| Abstract	December 2009	The Clean Water Act mandates that the chemical, physical, and biological integrity of our nation’s waters be maintained and restored. Physical integrity has often been defined as physical habitat integrity and as such, data collected during biological monitoring programs focus primarily on habitat quality; however, we argue that channel stability is a more appropriate measure of physical integrity. We highlight assessment tools that could supplement stream assessments and the Total Maximum Daily Load stressor identification process: field surveys of bankfull cross-sections; longitudinal thalweg profiles; particle size distribution; and regionally calibrated, visual, stream stability assessments. Benefits of measuring channel stability include a more informed selection of reference or best attainable stream condition for an Index of Biotic Integrity, establishment of a baseline for monitoring changes in present and future condition, and indication of channel stability for investigations of chemical and biological impairments associated with sediment discontinuity and loss of habitat quality.

Interior population trumpeter swan migration ecology and conservation. Midwest Fish and Wildlife Conference, Springfield, Illinois, U.S.A.	January 2020	The Interior Population of trumpeter swans results from reintroductions beginning in the late 1960s, with initially modest goals of re-establishing several hundred pairs of breeding swans. Since that time, the Interior Population has grown dramatically with upwards of 25,000 individuals counted in the 2015 survey. Because very little is known about movement ecology of this reintroduced population, we have initiated a 4-year study across the Interior Population to answer basic questions about

French, W. E., B. Vondracek, L. C. Ferrington, Jr., J. Finley, and D. J. Dieterman. Relative position of brown trout in winter food webs of groundwater-dominated streams using stable isotope analysis. Midwest Fish and Wildlife Conference, 26-29 January 2014, Kansas City, Missouri. Summer interactions of stream-dwelling brown trout Salmo trutta within food webs have been frequently studied; however, relatively little is known during winter within food webs. Groundwater may increase the availability of potential prey and create more favorable foraging conditions for trout by maintaining relatively warm winter temperatures. We used stable isotope analysis to examine the relative position of brown trout in the aquatic food webs of 13 streams across the Driftless Ecoregion of southeastern Minnesota. Two tissue types with differing turnover rates (fin and mucus) were used to examine temporal, and spatial variation in relative food web position of brown trout. Although relative food web position varied both temporally and by individual, brown trout stable isotope signatures indicated aquatic invertebrates were likely the predominant prey source. Additionally, brown trout may have used a combination of allochthonous and autochthonous derived resources within the winter aquatic food web.	January 2014	Relatively little is known about food webs of Brown Trout during winter. Although relative food web position varied both temporally and by individual, brown trout stable isotope signatures indicated aquatic invertebrates were likely the predominant prey source.
