Angler behavior in response to management actions on Nebraska reservoirs -- Part 2	December 2018	There exists interplay between angler participation and quality of fish in a lake. Variability in recruitment of fish among lakes should increase dispersion in densities of fish across a region, whereas movement of anglers among lakes should decrease dispersion in densities of fish across a region. Unlike fishery management efforts that in general operate on a local scale (i.e., single lake), these counteractive forces are likely stronger on a regional scale. Thus, incorporation of spatial and temporal patterns in angler participation into fishery management likely will require a shift in focus from lake-specific management to regional management. This shift in focus would be facilitated by an understanding of angler-participation patterns. The goals of this study are to understand 1) the participation patterns of anglers on multiple spatial and temporal scales; 2) how participation patterns of anglers’ influence fish populations and associated communities; 3) how management actions influence angler participation patterns and, in turn, fish communities; and 4) interactions and feedback mechanisms between and among angler groups and fish communities. Study findings should help biologists better determine appropriate lake-specific management objectives given the dynamic nature of angler participation and its interrelationship with fish populations.	Recreational fishing is the most influential factor structuring fish populations, especially in inland systems with intensive fishing pressure. Anglers often target apex predators such as largemouth bass and walleye, which can have important consequences for fish communities in lakes and reservoirs via top-down controls. To complicate matters, predator dynamics among fishes vary spatially (e.g., within and among reservoirs) and temporally (e.g., within and among years), as does angler participation. Even so, inland fishery biologists rarely incorporate spatial and temporal patterns, which also occur in angler participation and catches, into management strategies, possibly because little is understood about angler decisions to participate in the sport. Incorporation of spatial and temporal patterns in angler participation into fishery management likely will require a shift in focus from lake-specific management to regional management. This shift in focus would be facilitated by better understanding of factors affecting angler participation and harvest decisions. This project is a collaboration of researchers across multiple agencies and includes the University of Nebraska—Lincoln and the Nebraska Game and Parks Commission. Information gained on angler behavior will be important for increased effectiveness of fishery management, as well as increased effectiveness of angler recruitment and retention activities.

Chytrid fungus distribution in Nebraska	May 2014	Many worldwide amphibian population declines and mass mortality events have been attributed a fungal infection chytridiomycosis (chytrid) caused by the fungal zoospore Batrachochytrium dendrobatidis (Bd). Although the exact mechanism by which mass mortalities occur from chytrid is unknown, it is hypothesized that the chytrid fungus infects keratinized epidermal cells of postmetamorphic frogs with death caused by: 1) disruption of osmoregulation; 2) the absorption of a fungal toxin; 3) or a combination of these factors. Concern over the potential ecological consequences of such rapid and drastic extinctions has led to an increase in effort studying the potential effects of emerging infectious disease on amphibian populations. Furthermore, scientific and technological advances in non-invasive techniques to detect the chytrid fungus have changed the ability of researchers and managers to track the distribution of and measure the population fluctuations and declines caused by infectious disease such as chytrid. The chytrid fungus is known to occur in Nebraska and has been found in amphibian populations located in eastern Nebraska as well as along the Central Platte River. Although sporadic testing for the chytrid fungus in populations of native amphibians has occurred in Nebraska, a statewide survey has never been conducted. This lack of knowledge pertaining to the current distribution of chytrid the state must be rectified. Doing so will not only allow researchers to know where chytrid is currently found in the state, but also aid in the development of predictive models and help in the understanding of factors that may help or mitigate the further spread of chytrid. The primary goal of this study to determine the current extent of chytrid in Nebraska by swabbing larval amphibian populations statewide. Using PCR, the samples will be tested for the presence of Bd zoospores. The presence/absence of chytrid in amphibian populations will be used to model the distribution of chytrid based on environmental covariates associated with wetland condition and amphibian call surveys. The results of these models will be used to develop predictive maps of the potential spread of chytrid based on important environmental and anthropogenic variables. During the spring and summer of 2011 and 2012, researchers visited wetlands in eastern and central Nebraska. During site visits, tadpoles were captured using dip nets. At those sites where tadpoles were captured, each individual was swabbed using a sterile swab. In 2011 and 2012, 168 swabs were collected from 5 frog species at 21 sites. Preliminary PCR results detected chytrid in 62% of the sites. Additionally, chytrid was detected in at least one swab from each species. The detection rate (d) was highest in bullfrogs (n = 9; d = 1.00) and lowest in plains leopard frogs (n = 78; d = 0.10). The detection rate did not appear to vary between months (May – n= 56, d = 0.125; June – n = 112 d = 0.17). An additional 10 samples were collected during 2013. Sampling will continue during the spring and early summer of 2014.	None
Pollinator assemblages in Southeast prairies and sandstone prairies biologically unique landscapes	June 2015	The Southeast Prairies Biologically Unique Landscape (BUL) is part of the Southeast Nebraska Flagship Initiative, a partnership that includes The Nature Conservancy, Northern Prairies Land Trust, Spring Creek Prairie Audubon Center and the Nebraska Game and Parks Commission. The implementation of Flagship Initiatives—including that in the Southeast Prairies BUL—follows from the Nebraska Legacy Plan to implement a proactive approach to conserving non-game wildlife and biological diversity in an adaptive management framework. The overall goal is to determine how to most effectively and efficiently manage prairies while maintaining critical plant-insect relationships indicative of system functioning. This project aims to evaluate the current and potential viability of ecological systems within priority landscapes. It began as a pilot study in 2011 conducted by Bethany Teeters in which the bee assemblages were compared between extremely isolated prairie fragments and large, well-connected fragments. This was a continuation of Chris Wood’s work in which habitat factors that influence the structure of the pollinator community in the southeast prairies were examined. His goal was to determine which factors have the greatest impact on abundance and species richness in tallgrass prairie fragments. As most remnant prairie fragments are privately owned, this knowledge will be useful when approaching landowners about management techniques that benefit both agriculture and prairie conservation. After all, the majority of angiosperms are dependent upon pollinators for reproduction, including prairie forbs. Understanding population viability for various pollinator taxa and how that status differs across the landscape will help improve land management strategies that support conservation efforts. Research currently focuses on bees as a key insect group that provides an important ecosystem service: pollination. In 2012, comparisons of bee species richness, diversity, and abundances were made between the dominant grassland types in the southeast: remnant prairie or haymeadow, properties enrolled in the Conservation Reserve Program (CRP) and grazed pastures. These grasslands were evaluated as potential bee habitats based on floral resource availability. Nearly 6,000 individuals were collected over the season which were identified and sorted into functional groups. Future research will focus on questions of habitat connectivity in this landscape and other habitat factors that may help explain the assemblages and distribution of species. Chris and Bethany are currently combining species lists from the past few years of collection to identify and document new records for the area and the State of Nebraska. Such documentation is important for monitoring species distributions and determining changes in those distributions over time, especially if they correspond to changes in local or regional climate. The overall goal of all the work in this area is to evaluate the functioning of ecosystem services and identify important factors that influence the pollinator community in this landscape. Such information will be valuable for making appropriate land management and conservation recommendations.	None
Platte River Basin Timlapse	June 2015	Integrating photography with science is a dynamic approach for communicating research, and is an innovative method for extracting data. Conservation photography has been implemented and recognized as a communication tool for science and an influential means of sustaining and managing natural resources. Time-lapse photography is part of this emerging field and capable of conveying visual information of what is occurring within a system. Water scarcity is a global issue, with a leading example happening and developing in the Great Plains of Nebraska. The central Platte River basin hosts a convergence of uses, including irrigation for agriculture, power production, public municipality supplies, and critical habitat for numerous species. In collaboration with Michael Forsberg and Michael Farrell’s Platte Basin Timelapse project, this study aims to explore innovative approaches in the realm of science communication by combining time-lapse photography with remotely sensed ecological and phenological data. Water quality measurements and bioacoustics of bats, frogs, and birds will be integrated with time-lapse series to visually identify temporal and spatial variability patterns. Features will be extracted from the images to see if photographic attributes are correlated with water quality or call phenology.	None
Making adaptive management meaningful: translating science learning into policy decision making	December 2014	Adaptive management has been and continues to be implemented around the country and world, yet few examples exist of programs successfully implementing all six steps (Assess → Design → Implement → Monitor → Evaluate → Adjust) of adaptive management. A key break point in this process seems to be synthesizing collected data and using that synthesis to tell a story about what data say in regard to key questions and hypotheses in a way that is useful to decision-makers and results in positive changes in management or policy. Research will: 1. Explore the science and policy interface in a comparative study of several adaptive management programs, 2. Provide specific background on this issue as it relates to the Platte River Recovery Implementation Program, 3. Showcase decision analysis other tools that can be used as decision support in the Platte River and other adaptive management programs, and 4. Discuss opportunities for and challenges to bridging the science/policy gap.	None
Integrating adaptive management, resilience thinking and optimization	December 2015	The natural resources management paradigm has been shifting from traditional command-and-control to a focus on complex social-ecological systems and explicit recognition of uncertainty. Adaptive management is an approach combining management actions and scientific investigation to increase understanding of environmental systems. It is a structured, “learning by doing” method to management that embraces uncertainty and change. Resilience thinking acknowledges the presence of multiple stable states in nature and considers the extent to which a given system can absorb perturbation before shifting into a different organization of functions and processes. Central to resilience theory is the awareness of the ubiquity of surprise in social-ecological systems. Optimization is a conservation tool used to make transparent management decisions based on explicit values and objectives. Adaptive management, resilience thinking, and optimization have all been suggested as appropriate ways to implement the emerging social-ecological management paradigm, but translation into practice remains a challenge. Structured decision making is a process for making smarter decisions that involves the clear elucidation of problems, objective, alternatives, consequences, and tradeoffs. This research project seeks to explore how structured decision making can link resilience, adaptive management, and optimization in order to generate a cohesive method of implementing the emerging social-ecological paradigm. Research conducted as part of this project will involve: 1. Translating resilience theory into natural resource management practices using structured decision making; 2. Investigating how optimization can be used to address resilience objectives; 3. Exploring the potential for adaptive management under State Wildlife Grants, focusing on the Nebraska Natural Legacy Project; 4. Creating frameworks for operationalizing future natural resources management projects that engage adaptive management, resilience thinking, and optimization.	None
Impacts of wind energy development and operation on soil invertebrates	December 2013	The potential impacts of wind energy generation on wildlife and their habitats are not fully understood and vary greatly depending on the location of the wind facility. Wind energy development and operation can have direct and indirect impacts on wildlife. Direct impacts include deaths resulting from collisions and habitat loss from construction of roads, wind turbine pads, and other structures. Indirect impacts can include wildlife being displaced from preferred habitat through fragmentation or avoidance of the wind turbines, temporarily disturbed from an area, or forced to alter migration and/or movement patterns. Studies to evaluate the potential impacts of wind energy development on wildlife have been conducted for several years. Yet, there is still much more for researchers to learn. To date, most wind–wildlife studies have focused on the direct impacts to volant or flying animals such as birds and bats. More recent studies are looking at the indirect impacts on birds and large mammals. Very little research has gone into the potential impacts of wind energy development on soil invertebrates and insects. Soil invertebrates, such as the endangered American burying beetle, may be negatively impacted by wind energy development and operation. Through this UCARE project, we intend to investigate how and if soil invertebrates may be impacted by wind energy development through literature searches, and lab and field studies.	None
Evaluating the benefitsof higher diversity CRP plantings for at-rsik speceis	December 2013	Land enrolled in the USDA Conservation Reserve Program (CRP) covers more than a million acres in Nebraska. However, little attention has been given to the potential of CRP as a resource in the conservation of at-risk species. For policy and planning purposes, it is important to quantify the species composition of CRP plantings and the relative impacts of different grass and forb planting mixes on local diversity. For example, several designated at-risk butterfly species require specific plant species for successful reproduction. Additionally, forbs are needed as nectar sources for most adult species of butterflies. Landowners are not currently required to include any specific species in their CRP seeding mix, and forb diversity plantings vary. The project objective is to evaluate potential habitat benefits of a variety of CRP planting mixes for at-risk species, including birds, butterflies, bees and fish. During the summer 2013 field season, a large portion of time was spent setting up control plots and sampling areas, installing pitfall traps, learning auditory and visual cues to identify birds, and learning local vegetation. Two technicians assisted with all activities. The following tasks have been completed on the Smith's CRP site in Holt County, NE: 1. Ground dwelling invertebrate sampling: Pitfall trapping to sample ground dwelling insects palatable to upland bird chicks cross the control (standard CRP seed mix plantings) and pollinator (high forb, high diversity CRP seed mix plantings) plots. Three samplings occurred thus far: one in early June, one in early July and one in late July/Early August. 2. Pollinator sampling: Blue Vane traps were set up to sample pollinator assemblages across the control and pollinator plots in the site. This will provide us with baseline data to compare with future years, once the pollinator plots are established. Sampling occurred during summer 2013. Additionally, sweep net sampling (to capture, record and release butterfly species) occurred in late summer 2013. 3. Bird sampling: Point count surveys were conducted across the pollinator and control plots to establish both baseline habitat usage and a running list of bird species that visit and inhabit the entire site. Five point counts were conducted between mid-June and mid-July. The first sampling was delayed until mid-June due to the time required to learn bird calls, and to train the technicians. 4. Vegetation surveys: Vegetation surveys are continuously conducted across the pollinator and control plots using a cover/frequency protocol to track changes in diversity and grass to forb ratios. A total of 15 square meters is measured within every of the larger 18 control and pollinator plots. 5. Mapping: Extensive GPS survey of the field is continuous and will provide us with the ability to revisit sampling areas in future field seasons and the capacity to create user-friendly ways of disseminating our data to broad audiences.

Ecological models and biodiversity conservation in Nebraska landscapes	December 2014	Biodiversity is increasingly threatened worldwide by an array of anthropogenic stressors, including increased human population density, habitat loss and fragmentation, overhunting and overfishing, biological invasions, and climate change. In the North American Great Plains, agricultural practices have converted grasslands and wetlands into cropland, increasing food and energy production, but decreasing wildlife habitat. As global food and bioenergy demands continue to rise, agricultural conversion and intensification continue. The Nebraska Natural Legacy Project is a state wildlife action plan that aims at accomplishing the following objectives: 1. Reverse declines of at-risk species; 2. Recover species currently listed as state or federally threatened or endangered; 3. Keep common species common, and conserve natural communities. The plan identifies 39 Biologically Unique Landscape(s) (BUL) within Nebraska where conservation actions will be specifically targeted. A coarse filter/fine filter approach to conservation has been adopted in the plan, with the goal of benefiting the majority of species by managing at the community (coarse filter) level. Threatened species not encompassed by community-level management are then addressed specifically (fine filter). This project will develop distribution models for species and/or communities identified as conservation targets within Nebraska BULs, with the goal of integrating modeling into an adaptive management conservation framework for BUL-scale management. Expected products for BULs include habitat suitability ranks, assessments of functional connectivity for suitable habitat patches, baseline community area and species abundance estimates, identification of locations for focusing additional sampling and monitoring efforts, predicted community distributions and species abundances under an array of plausible management-based scenarios, evaluation of progress toward accomplishing established conservation objectives, and identification of suitable locations for the reintroduction of extirpated target species. Modeling techniques will be utilized according to data availability and their propriety for addressing specific research questions. Within an iterative framework, conservation objectives, management actions, and modeling techniques may be altered as additional information supporting adjustments is obtained.	None
Dynamics of resilience in complex adaptive systems	December 2017	Ecosystems are a type of complex system, and as such share general rules of behavior with other types of complex adaptive systems. Research across a wide variety of disciplines has uncovered rules of system dynamics that address features of self-organization and emergence. Work in the field of ecology has proposed that resilience may be an emergent phenomenon of complex adaptive systems, and in particular, social-ecological systems. Resilience is the amount of disturbance a system can absorb or buffer while staying organized around the same key structures, processes, and functions. As our understanding of non-linear dynamics and complex systems has grown in recent years, the concept of resilience has exploded, and a great deal of work has been done to understand how resilience emerges and what system components and interactions comprise resilience. One of the key findings is summarized in the cross-scale resilience model, which proposes that the distribution of species and the functions they represent within and across the scales of an ecosystem plays a key role in system resilience. While most previous work has been explicitly focused on social-ecological systems, there is some tantalizing evidence to suggest that resilience and the cross-scale model may also be applicable to other types of complex adaptive systems, such as economies. In a more applied exploration of these ideas, the role of species abundance, coupled with their distribution of function, is an element of the cross-scale model that remains unexplored. This project has two objectives. 1. Explore the cross-scale model in greater detail at both ends of the research spectrum, building the theoretical foundations of the cross-scale model and thus its applicability to other complex adaptive systems, in order to expand understanding of the cross-scale model to incorporate species’ abundances and potentially use it as a tool for resource managers to use for identifying impending regime shifts. 2. Focus on improving our understanding of the relationship between cross-scale distributions, species abundance, and regime shifts at a system level by using a comparison of a highly disturbed river basin system (the Lower Columbia River Basin, USA) against a less disturbed basin (the Fraser River Basin, Canada).	Slow global change can lead to abrupt ecological responses if resilience is exceeded. Identifying leading indicators of resilience thresholds is critical for managing ecosystems, and avoiding catastrophic change. This project created a working group at the USGS Powell Center for Synthesis to address a broad range of questions related to resilience and abrupt ecological change, and included international partners and USGS, USFWS, USNOAA, and the USEPA. Amongst other results, we developed and forwarded the concept, including methods, of identifying spatial regimes.
Better soil for birds	May 2016	The primary outcome objective is to provide landowners enrolled in the Conservation Reserve Program (CRP) in Nebraska’s Niobrara Valley with a better understanding of how four, major mid-contract management activities impact key attributes of soil health. As landowners and managers are faced with the arduous task of weighing the various economic and ecological tradeoffs of different mid-contract management strategies, soil health is often overlooked with potentially detrimental consequences for the long-term value and resilience of their land. This is especially important as landowners are faced with the option to re-enroll in CRP, with uncertain climatic and economic futures looming on the horizon. We believe that our work will render CRP lands more valuable and resilient over the long-term for private landowners by incorporating soil ecological knowledge into more recent management objectives that often focus exclusively on promoting short-term upland bird habitat. More specifically, our research objectives include: 1. Tracking and establishing a set of measurable soil health attributes as identified by private landowners, and how they are differentially impacted by the four major mid-contract management strategies; and 2. Providing applicable, relevant information to private landowners, land managers and USDA NRCS personnel in an effort to promote smarter, adaptive management decisions that balance short- and long-term objectives to meet CRP contract requirements and landowner-desired outcomes alike.

Bat movements across transforming landscapes	June 2018	Nebraska has a diverse mix of resident and migratory bat species. Because of the diversity of habitats found throughout Nebraska, there is no place in the state where all 13 bats species occur together. The Nebraska Natural Legacy Project State Wildlife Action Plan lists five bat species as either Tier I or Tier II at-risk Species. At the national level, northern long-eared myotis (Myotis septentrionalis) is currently being considered as a candidate species under the Endangered Species Act. Bats provide critical ecosystem services in the form of insect consumption, pollination, and seed dispersal. The economic importance of bats was estimated in 2011 to be about $22.9 billion to the agricultural industry or on average $74 per acre. In a state dominated by agriculture, such as Nebraska, the loss of bats could result in increased money spent for pesticides and other insect control measures. The potential synergistic impacts of wind energy development and white-nose syndrome on bats could have unanticipated consequences in Nebraska and around the nation. The discovery of dead bats under wind turbines was unanticipated by scientists and wind energy companies. The seven most common bat species found dead near wind turbines are all either resident or migratory bats found in Nebraska. White-nose syndrome (WNS) is a deadly fungus that affects hibernating bats. Four of the eleven bat species affected are found in Nebraska. Potential negative impacts of wind energy development on bats can be avoided or minimized through siting and operation that take into consideration bat presence and activity. We need more knowledge of bat migration patterns and habitat use in Nebraska to help protect bats and their habitats from the potential impacts of wind energy development, and to help utility companies, wind energy developers, and facility owners to manage and mitigate the effects of new and existing wind energy facilities. Through the deployment of over 20 ultrasonic acoustic detectors for two years, we plan to identify when and where bats are moving in eastern Nebraska during spring and fall migration and summer residence. Information gathered from this project will be shared in a variety of formats and used to further promote sound resource management practices in regards to wind energy development. Partners on this project include the Nebraska Wind Energy and Wildlife Project, the U.S. Fish and Wildlife Service, the Nebraska Game and Parks Commission, and the University of Nebraska–Lincoln.	Bat migration is poorly understood, yet migratory bats are endangered by wind development. This project is collaborative with the Nebraska Game and Parks Commission and the Nebraska Environmental Trust. Results will help utility companies, wind energy developers, and wind facility owners avoid, manage, and mitigate the effects of new and existing wind energy facilities.
Amphibian Occupancy, Functional Connectivity, and Resilience of Rainwater Basin Wetlands	May 2018	Both the quantity and overall quality of wetlands have severely declined globally. Many remaining wetlands exist in landscapes dominated by agricultural production. The Rainwater Basin is a region of Nebraska characterized by shallow wetlands located in an agricultural matrix. Following European settlement in the mid-to-late 19th century more than 90% of historic wetlands were filled or farmed through. The remaining wetlands exist in an area of intensive agriculture that has further isolated wetlands and may affect their function, and reduce the resilience of the Rainwater Basin. Resilience of a system is the amount or magnitude of disturbance a system can absorb before it is pushed into a new stable state. Resilience can be eroded over time by small perturbations leaving the system more vulnerable to a catastrophic change. For the Rainwater Basin, we are interested in the resilience of the functional connectivity among wetlands, for amphibian species. Amphibians are an important taxonomic group that provide services by controlling insects, serving as food for migratory birds and other species, and integrating terrestrial and aquatic systems. Amphibians are sensitive to environmental contaminants and can be used as an indicator of water quality, system health, and resilience. Occupancy of amphibians, functional connectivity of remaining wetlands, and acute and chronic effects to amphibians from commonly applied agrichemicals will be investigated. This project seeks to assess how agricultural land-use may affect resilience of a large wetland complex.	Both the quantity and overall quality of wetlands have severely declined globally. Many remaining wetlands exist in landscapes dominated by agricultural production. Understanding how the spatial distribution of wetlands has changed over the past 50 years will provide insight into potential affects on different amphibian species. This project is a collaboration between the Nebraska Game and Parks Commission and the Rainwater Basin Joint Venture. Results can be used to guide the restoration of wetlands within the Basins, and ongoing endeavor.
Ecology of swift fox in Nebraska	December 2018	Swift fox, (Vulpes velox) is a small species of fox native to short- and mixed- grass prairies of the Great Plains, including Western Nebraska where they are listed as a Tier-1 at-risk species. Habitat loss is a major contributor to population declines with only 40% of Nebraska still containing suitable grassland habitat. Still, swift fox do not occupy all suitable habitat. Why might a species fail to use seemingly good habitat? Coyotes might be the answer. Unlike swift fox, coyotes are highly adaptable, and, as their bigger cousin, can displace swift fox from otherwise suitable habitat. Coyotes may gain further advantages when grasslands are converted for agricultural and energy development. Thus, swift fox conservation requires understanding where swift fox roam and how they interact with coyotes and people. It isn't easy surveying the entire western third of Nebraska for a nocturnal species that spends much of its time hidden in dens. Because most swift fox habitat is on private land, our efforts to study where swift fox live, and why, require us to collaborate with privates landowners throughout western Nebraska, as well as students from the University of Nebraska-Lincoln and Chadron State College. Together, we work to understand how best to conserve swift fox in the face of change.	In Nebraska, the loss and degradation of grasslands has significantly impacted many grassland species, including the swift fox (Vulpes velox). A Nebraska Natural Legacy Plan Tier-1 at risk species, swift fox are estimated to occupy as little as 20-25% of their historic range; however, despite their Tier-1 status, little is known about the true distribution of swift fox. With increasing interest in developing infrastructure in Western Nebraska for gas, oil, and wind energy there is a clear need to document the distribution of swift fox, and identify threats to swift fox populations. Traditional studies of species distribution focus on identifying the habitat attributes, most notably vegetation, that best predict the spatial patterns observed in nature. However, in canid systems, there is clear evidence that intraguild interactions play an important role in predicting species distribution and habitat use, especially for smaller canid species. As the largest extant canid in the shortgrass prairie, coyote are dominant to swift fox and often cited as an important source of mortality. As such, increases in the abundance and distribution of coyote following the development of the western Nebraska may have inadvertently restricted the range of swift fox despite the availability of suitable vegetative conditions. Starting in 2013, the Nebraska Game and Parks Commission, the Nebraska Department of Roads, the Nebraska Environmental Trust, and the U.S. Forest Service - Nebraska National Forests and Grasslands working in collaboration with the Nebraska Cooperative Fish and Wildlife Research Unit, the University of Nebraska-Lincoln and Chadron State College began a five year project to document the occurrence of swift fox in Western Nebraska and identify the anthropogenic and ecological factors that limit swift fox distribution. Our goal is to identify where swift fox are located and identify the ecological mechanisms shaping the distribution of canid communities in Nebraska by developing and testing a series of species distribution models based on the habitat requirements and intraguild interactions of Nebraska’s canid community
Habitat decisions in altered landscapes: Behavioral and physiological consequences for long-distance migrants	December 2015	Increasing agricultural intensity is likely altering habitat characteristics that influence the condition and migratory success of long distance migrant such as shorebirds because agricultural landscapes can have reduced food availability. Although shorebirds demonstrate dietary flexibility during migration, overall depression in food resources and limited habitat availability may induce further competition. Still, previous research suggests that migratory shorebirds prefer agrarian habitats over native habitats, despite the relative dearth of resources— a preference which may suggest the presence of an ecological trap as these habitats still clearly display cues that indicate quality habitat. Closer examination indicates that shorebirds may compensate for limited food availability by foraging more actively; however, the degree to which behavioral flexibility buffers against the negative impacts of foraging in areas with fewer resources remains unclear. It is possible that altering the landscape has resulted in fitness consequences for migratory shorebirds by reducing the energetic benefits associated with preferred habitats. In general, differences in the availability of habitat across the landscape, as well as annual and regional variation in habitat predictability, makes this a unique system in which to test the consequences of habitat decisions for migratory shorebirds. In addition, the wide spectrum of natural variation and anthropogenic change across a relatively short distance presents a rare opportunity to understand the scale at which plasticity in habitat decisions is expressed during migration. The goals of this study are to examine patterns of stopover habitat use by migratory shorebirds, the habitat characteristics of stopover sites, and how habitat characteristics may influence condition and potentially fitness for shorebirds during spring migration.

Assessing the indirect effects of predation risk on pheasant behavior and habitat use	January 2015	Predation is a strong selective force that shapes prey morphology, physiology, and behavior and acts over evolutionary as well as ecological time. Studies of predator-prey dynamics traditionally focus on the obvious consumptive impacts (direct mortality) of predators on their prey, but non-consumptive impacts have been demonstrated in virtually all taxa and their effects are wide-ranging; influencing micro- and macro-habitat use, time allocation patterns, species distribution, population growth, and species interactions. In order to evaluate the non-consumptive impacts of predation risk, specifically, plastic antipredator responses prompted by perceived predation risk and their associated costs, we will evaluate the behavioral responses of ring-necked pheasants (Phasianus clochicus) to recreational hunting. This study system presents a unique opportunity to investigate non-consumptive predation risk in the absence of consumption (i.e., the cost of perceived predation risk without actual risk). In our study system, recreational hunting represents an actual, consumptive predation risk for male pheasants, while females are exposed to potentially lethal predators, receiving feedback and reinforcement for the expression of antipredator responses in the presence of recreational hunters. As such, our study system is ideal in that consumptive predation risk (experienced by roosters only) and non-consumptive predation risk (experienced by both roosters and hens) are isolated. Assuming males and females perceive similar levels of predation risk and that the effects of mortality and perceived predation risk are additive, we are able to evaluate the relative effects of consumptive (mortality) and non-consumptive (perceived) predation risk on pheasant antipredator responses.

The social-ecology of an intensively managed ecosystem: pheasants and pheasant hunters in Southwest Nebraska	December 2019	Ring–necked pheasants (Phasianus colchicus) are a culturally and economically important game species. Across the Midwest agroecosystems have historically served as important habitat for pheasants, but the intensification of agricultural has significantly altered the landscape resulting in a long–term decline in pheasant populations. The Conservation Reserve Program (CRP) has helped to mitigate habitat loss and slow the rate of population decline, but enrollment in CRP is declining. Given the importance of pheasants to Nebraska, managers are interested in developing programs that will continue to support pheasant populations while ensuring hunting opportunities. In southwest Nebraska, the Nebraska Game and Parks Commission intensively manages for pheasant habitat and pheasant hunting opportunities with the goal of producing the best pheasant hunting experience for the most hunters. Starting in 2012 we began working with the Nebraska Game and Parks Commission to monitor pheasants and pheasant hunters in the region to better understand how pheasants use managed agroecosystems, how hunters perceive and use public access, and how pheasants and pheasant hunters interact. Since the start of the project we have captured and radio collared hundreds of pheasants and recorded thousands of locations on where pheasants are roosting, eating, loafing and nesting. At these locations we have collected information on vegetation characteristics, climatic conditions, and food resources to understand the ecological needs of pheasants. To understand changing population dynamics, we monitor the survival of pheasants throughout the year and each spring we monitor 20–70 nests collecting information on reproductive investment and success. We also monitor seasonal movements of pheasants and responses to management and regulations such as the opening of the hunting season or wheat stubble management. In addition to monitoring pheasants we are collecting information on hunter movements and harvest to understand how hunters interact with pheasants in the field. The findings from this study are helping us to understand the complex dynamics between how uncontrollable factors such as weather interact with habitat and harvest management to affect pheasant population dynamics in an intensively managed ecosystem.

At these locations we have collected information on vegetation characteristics, climatic conditions, and food resources to understand the ecological needs of pheasants. To understand changing population dynamics, we monitor the survival of pheasants throughout the year and each spring we monitor 20–70 nests collecting information on reproductive investment and success. We also monitor seasonal movements of pheasants and responses to management and regulations such as the opening of the hunting season or wheat stubble management. In addition to monitoring pheasants we are collecting information on hunter movements and harvest to understand how hunters interact with pheasants in the field. The findings from this study are helping us to understand the complex dynamics between how uncontrollable factors such as weather interact with habitat and harvest management to affect pheasant population dynamics in an intensively managed ecosystem.
Influence of the Conservation Reserve Program on Population Structure, Demography, and Space Use by Greater Prairie-Chickens in Kansas and Nebraska	September 2028	The U.S. Department of Agriculture, Conservation Reserve Program (CRP) is considered the most effective large-scale conservation effort affecting wildlife species in the United States. In the Great Plains, 4.18 million acres of CRP occurs in Kansas and Nebraska, potentially affecting a large number of wildlife species, including many grassland species that may rely on these landscapes for persistence and resilience to dynamic environments. Few studies have assessed the response of the greater prairie-chicken to the establishment of CRP, a species which has lost much of its historical range and is in decline. Kansas and Nebraska support the majority of extant greater prairie-chickens, though populations face multiple threats which may limit movement among remnant populations. The project will hierarchically evaluate the influence of CRP on greater prairie-chicken populations thought the collection of movement, vegetation, and genomic data sets and produce science that will form management actions on CRP enrollment as well as the species in the region.

Influence of environmental thresholds on trajectories of freshwater assemblages with implications for building climate resilience across prairie landscapes	September 2029	Land use, geomorphic change, and fragmentation threaten prairie stream biodiversity and ecosystem function through changes in flow, temperature, and connectivity. Climate change will exacerbate these changes and likely lead to further shifts in species composition and biodiversity loss. Conservation and management actions needed to counter shifts in species composition and biodiversity loss depend on identifying environmental thresholds (i.e., tipping points) after which undesirable state shifts occur. Yet, identifying systematic environmental thresholds across freshwater ecosystems remains elusive despite the recognition that reaching thresholds may lead to trajectories with irreversible changes. The substantial climatic gradient across the Great Plains prairie ecoregion provides an ideal setting to evaluate environmental threshold responses in freshwater streams. Further, prairie streams are embedded within a matrix of diverse land use and geomorphic conditions. A region-wide perspective will thus allow natural resource management agencies to learn from and anticipate change based on current spatial variation in, for example, the rate and magnitude of agricultural conversion to urban land use, or upper thermal limits of organisms from south to north, across the study area. management and conservation actions (e.g., provide environmental flow allocations) that facilitate species persistence. Specifically, we propose to:<br><br>1) aggregate and quantify the spatial and temporal landscape of environmental gradients, including temperature, precipitation, and land use and characterize spatial and temporal patterns of aquatic assemblage diversity,<br><br>2) identify threshold responses in aquatic assemblage structure to environmental gradients, and<br><br>3) identify and aggregate data to support management actions that resist reaching thresholds, direct community trajectories, or accept change and promote tracking of aquatic assemblages to climate shifts.

Have population size fluctuations influenced the genomic diversity in monarchs?	June 2026	North American monarch butterflies are a charismatic pollinator, in part, because of their unique long-distance migration and formation of large clusters of individuals at winter roosting sites. Through monitoring at roost sites, marked declines in monarch numbers were detected. The eastern population segment of monarchs that winters in Mexico declined by 90% with the western population segment estimated to have declined by 95% since the late 1990s. Further, eastern and western segments of monarchs are genetically differentiated, indicating the two regions are demographically isolated. The marked declines experienced by monarchs across North America prompted concerns about the persistence of the unique behavioral segments of the species and capacity of the species to respond to current and emerging threats.<br> <br>The effective population size (and thereby retention of genomic diversity) of species underlies a populations’ capacity to adapt and respond to changes in the environment in both current and future conditions. Dramatic reductions in census sizes not only reduce the capacity of populations to retain genomic diversity but also reductions allow for the expression of deleterious mutations that are present in the population at low frequency, which can further erode the viability of populations in decline. Evaluation of the impact that the decline has on the effective population size of monarchs, therefore, is needed to inform resiliency and population persistence forecasts under projected future conditions.

Evaluating spatial distribution and composition of mesopredator communities in western Nebraska	July 2027	Mesopredators are important components of animal and plant communities and play a role in maintaining ecosystem function and health. Not only does the presence of predators on the landscape have a strong influence on prey density and vital rates, mesopredator composition has cascading effects on species and ecosystem processes. Within Nebraska, scant data are available describing predator composition, occurrence and distribution. Given the influence mesopredators have on species, data on predator communities are needed to address knowledge gaps regarding population dynamics of harvested species and ultimately inform management strategies for both predator and harvested species. Our project will investigate how predator presence and community composition in Nebraska vary in relation to landscape features, land cover types, and other vegetation characteristics to inform decisions regarding habitat management.

Assess reference condition of small-mammal population dynamics and genetic variation prior to Ambler Road development and ongoing climate change	September 2028	Small mammals play a vital role in boreal and Arctic ecosystems in Alaska. As local and resident, keystone species in food webs with quick generation times and small home ranges, small mammals are sensitive bioindicators of local disturbance, including climate change and development. In Denali National Park, small mammals have been studied for 30 years (1992-2022) as part of the Central Alaska Network Long-Term Monitoring program. Over many years, rain, snow, and growing season temperatures were strongly associated with variation in plant primary productivity. Both vole and hare abundance cycles showed a four-fold change in amplitude (peak) that corresponded to long-term changes in primary productivity. As climate change continues to affect temperatures, primary productivity and growing season, we can expect changes in small-mammal populations movements, ranges and cycles that may drastically influence boreal and Arctic ecosystems. Our project will compare reference condition data - genetic diversity, genetic structure - as well as population demographic data among Denali, Gates of the Arctic, and Kobuk Valley national parks. These data are central for comparative research and informed dialogue with industry to establish pre-development mitigation strategies by providing pre-development snapshot of population status preceding future climate change and development.

ESTIMATING NORTH AMERICAN RIVER OTTER (LONTRA CANADENSIS) POPLULATION SIZE USING DNA FROM SCAT	December 2010	River otters (Lontra canadensis) are a state threatened species in Nebraska. Their rare and elusive nature makes them particularly difficult to study. Non-invasive genetic sampling is a new technique in which the DNA of the target species is collected from scat or hair samples and used to answer questions regarding the population. In September of 2009 a study began with the aim of using DNA from river otter scat to estimate the population size of the Big Bend Reach of the central Platte River. Scat samples were collected once in September on a 13 miles stretch of river and then again in October. DNA extraction was completed in June of 2010 and further analysis of the DNA is expected to be completed this fall. A population estimate for otters on the Big Bend Reach of the Platte River will be important in an overall state management plan. The information gained from this study will also be useful in performing a larger, statewide study to determine otter populations in other areas throughout Nebraska.	None
THE EFFECT OF COMMON REED ON RIVER OTTER HABITAT USE	December 2010	The recent invasion of Phragmites australis (common reed) in the Big Bend region of the Platte River has made the need to examine its potential effects on river otters more critical. The ability of P. australis to rapidly alter the landscape could have large affects on a population that may still be vulnerable, such as river otters. Using locations from radio tagged river otters (Lontra canadensis) along the central Platte River in conjunction with GIS, this study will determine if otters use river ways with P. australis, or if otter den use in areas with P. australis is more or less than expected relative to availability, and will identify any differences in otter use of areas before and after P. australis treatments. This study will increase our understanding of the effects of this invasive plant on river otters—a flagship species for non-game conservation. Data collection ended in December of 2009 with eighteen otters successfully implanted with transmitters and over one thousand locations being recorded. The data is currently being analyzed and will be completed in December of 2010.	None
Habitat use and home range of otters	December 2010	River otters became reestablished in Nebraska following their reintroduction in the mid 1980s and early 1990s. The species is currently listed as threatened in Nebraska (S2). Despite the high profile of the reintroduction and the otters’ role as a flagship species, relatively little is known about river otter ecology in Nebraska. The Nebraska Cooperative Fish and Wildlife Research Unit with the Nebraska Game and Parks Commission (NGPC) initiated this project in October 2006 with the objective of collecting home range and habitat use information on river otters along the big bend area of the Platte River using remote sensing (radio telemetry). We captured and radio-tagged eighteen northern river otters on and near the Platte River, a core component of the specie’s distribution in Nebraska. This project has recently completed the collection of home range and habitat use information on river otters along the big bend area of the Platte River. Data collected, in conjunction with the results of an ongoing river otter health and reproductive survey and results from the Nebraska Game and Parks Commission’s annual otter bridge survey, will help close existing information gaps and contribute to the creation of the Nebraska River Otter Management Plan and the Statewide Comprehensive Conservation Plan. This is one of the largest otter tracking projects in the United States and the only current project in the Midwest.	None
PLATTE RIVER WATERSHED ECOSYSTEMS SERVICES ON NATIVE AND RESTORED GRASSLANDS	September 2014	This new research project will focus on ecosystem services provided by native and restored grasslands in the Platte River watershed, including land enrolled in the USDA Conservation Reserve Program (CRP). Although empirical data has indicated that grasslands provide a variety of services important for humankind, including habitat for crop pollinators, carbon sequestration, and erosion control, little research has been undertaken that compares the functioning of high quality virgin prairie with either high or low-diversity restorations. This research will include comparisons of specific ecosystem attributes in each grassland type while also exploring how pockets of prairie (surrounded by intensive agriculture) add to the resilience of the system.

Assessing local and regional variability in productivity and fidelity of grassland birds on National Park Service units in the Great Plains	May 2011	National Park Service (NPS) units in the Great Plains provide breeding habitat for many grassland birds. However, little is known about the quality of this habitat and more extensive study into the avian breeding ecology at these sites has been recognized as necessary. A short-term study on songbirds at three NPS properties complemented current NPS monitoring, providing an among park comparison of nest success—a prohibitively labor-intensive and expensive process when conducted on a regional scale. Park managers need lower-cost data for informed decision-making, and measuring site fidelity is a potentially less expensive means of monitoring breeding site quality. The project used unique methods—stable isotope analyses of avian tissues—to evaluate variability in site fidelity of grassland birds at three NPS units in the Great Plains: Homestead National Monument, Nebraska; Pipestone National Monument, Minnesota; and Tallgrass Prairie National Preserve, Kansas. Birds that breed successfully at a location will often return to that location again (site fidelity). Current extrinsic markers used in monitoring site fidelity were inadequate for small birds; stable isotope analyses provided an alternative. This project evaluated the extent to which stable isotope analyses could be utilized to measure site fidelity in breeding grassland birds, specifically four target species: dickcissel (Spiza americana), grasshopper sparrow (Ammodramus savannarum), eastern meadowlark (Sturnella magna), and western meadowlark (Sturnella neglecta).

Scenarios of Climate Change and Land Use Change and Biological Invasions	December 2012	Biological invasions are a growing threat to both human enterprise and ecological systems. Estimates of costs associated with non-indigenous species in the United States exceed $120 billion per year. Ecological costs are more difficult to quantify, but include the extinction of indigenous biota and changes in ecological processes, with concomitant losses of ecosystem services and capital. Climate change will almost certainly exacerbate problems with invasive species. A number of investigations have indicated that regional change in climate will affect plant invasions in the Great Plains. Observed or predicted alterations of climate include earlier onset of spring, warmer winters, spatial and temporal changes in precipitation patterns, and reduced snowpack in the Rocky Mountains—resulting in lower runoff to Great Plains’ streams. However, much remains unknown concerning the relationship between climate change and biological invasions. The purpose this study is to develop a gap analysis of research and monitoring needs for biological invasions as mediated or affected by climate change in the Northern Great Plains of the USA. This analysis is in support of the development of a Climate Effects Center in the Great Plains, and will include a gap analysis of: 1) current research; 2) research needs and 3) monitoring needs. Additionally, we will begin work on developing scenarios of climate/landuse change effects on species invasions and range contractions, and the effects of policy interventions on the impacts of invasions driven by climate change.

Southeast prairies biologically unique landscape and sandstone prairies biologically unique landscape research	December 2012	The Southeast Nebraska Flagship Initiative is a partnership formed through the Nebraska Natural Legacy Program and includes The Nature Conservancy, Northern Prairies Land Trust, Spring Creek Prairie Audubon Center and the Nebraska Game and Parks Commission. The implementation of Flagship Initiatives—including that in the Southeast Prairies Biologically Unique Landscape (BUL)—follows from the Nebraska Legacy Plan to implement a proactive approach to conserving non-game wildlife and biological diversity in an adaptive management framework. The overall goal is to most effectively and efficiently manage prairies, while maintaining critical plant-insect relationships indicative of system fluctuation. Our aspect of the project has two major objectives aimed at conservation of at-risk species and biological diversity. (1) Evaluate on-going, private-lands habitat work to improve the location, conservation goals, and methods of those projects. (2) Evaluate the current and potential viability of ecological systems within priority landscapes. The second objective will inform the first. Understanding population viability for various taxa and how that status differs between more and less fragmented areas, as well as other variables, will help to more wisely select locations and strategies for management and conservation projects. We are focused on three key insect groups that provide important ecosystem services: pollinators, ants and ground beetles. Pollinators are important in that 65% of flowering plants depend upon them for reproduction, including many prairie plant species. Ants make up a huge portion of the insect biomass in prairies, and are important for soil aeration and drainage, seed dispersal and nitrogen cycling. Ants and most ground beetles are important predators, keeping many herbivorous insect populations in check. This research intends to determine the factors having the greatest impact on the abundance and species richness of these key insect groups in tallgrass prairie fragments. Factors may include vegetation structure, floral composition, litter depth, fragment size, fragment shape, fragment isolation or the composition of the surrounding landscape. Understanding the impact of these factors may improve use of conservation resources through targeted decision–making about what fragments to preserve, or where grasslands should be planted to best supplement prairie fragments, and will also be useful when approaching landowners about techniques benefiting both agriculture and prairie conservation.

Wetland Condition Assessment	May 2014	This project will add approximately 110 additional sample locations in support of the U.S. Environmental Protection Agencies 2011 National Wetland Condition Assessment. A network of assessment sample locations will be established in 11 different Nebraska wetland complexes and these will be used to track changes to the health and condition of Nebraska’s wetlands. Cooperators of this project represent 17 different agencies and organizations. In the years 2011 to 2013, a field team will visit each sample location and collect wetland assessment data. The data collection methods will conform to the protocol established by the U.S. Environmental Protection Agency. The indicators that we are considering for assessment include vegetation, algae, macroinvertebrates, amphibians, water quality, soils, and hydrology. Data will enable the evaluation of seasonal and annual changes in wetland condition. Outcomes of this project will be an improved understanding of the condition of Nebraska’s wetlands that can be used to target wetland conservation efforts, track changes in invasive species distribution, evaluate potential climate change effects on wetlands, and describe the range of reference conditions for key and vulnerable wetland complexes in the state that are also representative of many wetlands throughout the Great Plains.

Nebraska Invasive Species Project	December 2014	This five-year project continues the work begun with funding from the Nebraska Environmental Trust. However, while many of the same goals exist, the project now takes on many new tasks in collaborating with the Commission. For example, the project recently released a draft of the Nebraska Aquatic Nuisance Species Management Plan. Similar plans are in effect in most other states but is lacking in Nebraska. Other invasive species management plans are scheduled for development, encouraging cross-agency collaboration even further. The now fully equipped education and outreach program is reaching out to broad audiences across the state, and has recently focused on state policy makers in hopes of solidifying upcoming invasive species legislation. The Invasive Species Newsletter is now distributed electronically to around 400 people. With five more years of funding, the future of the project lies in many more collaborative efforts in invasive species research and management in Nebraska.	None
Adaptive management framework for Nebraska Natural Legacy Plan.	December 2014	The primary objectives of this project are to develop theoretical and empirical techniques that facilitate the integration of research and monitoring into the management of non-game species, including consideration of the complex trade-offs between social, economic, and biological factors that may facilitate and constrain effective wildlife management. The research project will include a synthesis of literature to identify effective techniques and synthesize approaches in the region, as well as an opportunity to work with area wildlife managers from Nebraska Game and Park Commission, U.S. Fish and Wildlife Service, The Nature Conservancy and others to test these techniques in the field within an adaptive management framework. Ultimately, the project will develop research projects within these guidelines on topics identified as priorities by natural resource mangers within the state of Nebraska. The project will develop and integrate monitoring and adaptive management into the implementation of state wildlife action plans.	None
Relationship between diversity and function	December 2010	Because restoration of grasslands is an important on-going management activity on many public lands in Nebraska, we are investigating the relationship between species diversity in prairie restorations, and ecological functions at relatively large spatial and temporal scales utilizing restorations along the Platte River in south central Nebraska. The relationship between restoration diversity and ecological functions (e.g., pollination, soil development, resistance to invasion and herbivore control) remains poorly understood. Invasion by aggressive plant species, erosion of diversity over time, and failure to withstand drought or other disturbances are all possible results of unsuccessful restorations. This project seeks to understand how grassland plant diversity affects the provision of ecological services.	None
Adaptive management of prairie remnants for legacy goals	May 2012	Purpose. The Southeast Nebraska Flagship Initiative is a collaborative partnership aimed at the conservation of biological diversity and at-risk species in four priority areas in the southeast corner of the state. The partnership was formed through the Nebraska Natural Legacy Program and includes The Nature Conservancy, Northern Prairies Land Trust, Spring Creek Prairie Audubon Center and the Nebraska Game and Parks Commission. Within the partnership there are focus groups for outreach, private lands habitat work, and research/evaluation; each incorporate other partner organizations. The Research and Evaluation focus group currently includes faculty from the University of Nebraska-Lincoln and University of Nebraska Omaha, as well as scientists from the Nebraska Cooperative Fish and Wildlife Research Unit, Nebraska Game and Parks Commission, The Nature Conservancy and Northern Prairies Land Trust. The implementation of Flagship Initiatives including that in the SE Prairies Biologically Unique Land�scape follows from the Nebraska Legacy Plan which implements a proactive approach to conserving non-game wildlife and biological diversity in an Adaptive Management framework. The implementation of adaptive manage�ment, here defined as conducting management experiments that place competing hypotheses at risk and reduce identified sources of uncertainty while managing trust landscapes, is simplified because the SE Prairie Flagship is a partnership between managers, practitioners and academicians who share the common goal of improving prairie management. The overall goal is to manage prairies (via size of parcels enrolled in conservation measures, spatial aspects of location of particular parcels and groups of parcels) in the SE Flagship Biologically Unique Landscape in the most cost effective and efficient manner while maintaining critical plant-insect relation�ships (parasitoids, pollinators) indicative of system function. We are uniquely situated to initiate this program because we have flagship funding in place, the research steering committee represents the important stakeholders, and the Legacy Plan suggests an adaptive management approach. This is the opportunity to demonstrate one such approach. Objectives: The research and evaluation focus group is working toward two major objectives, both aimed at conservation of at-risk species and biological diversity. 1. Evaluate private-lands habitat work that has been occurring for a number of years in order to improve the location, conservation goals, and methods of those projects. 2. Evaluate the current and potential viability of ecological systems within the priority landscapes, especially related to degree of habitat fragmentation in those landscapes. This second objective is designed to inform the first. By understanding the population viability for various taxa and how that status differs between more and less fragmented areas�as well as other variables such as plant diversity, we will able to more wisely choose both the location and strategies management and conservation projects. Tasks. In 2008, pilot data were collected on plant and insect communities at 13 sites in the Southeast (SE) Prairie Biologically Unique Landscape, one of the four landscapes covered by the Flagship Initiative. 1. We are expanding our geographic range outside of the 2008 study area in order to include more isolated prairie sites and increase the range of variability. 2. A graduate student from the University of Nebraska-Omaha will investigate pollinator populations and the relationships between pollinators and landscape fragmentation. 3. A University of Nebraska-Lincoln (UNL) graduate project will investigate insect communities, including overall insect community composition, richness and abundance of predator and parasitoid insects between sites. Measures of specific plant/insect host relationships (e.g., specialized seed herbivores and their host plants) will focus on the relationship to floristic quality and/or landscape fragmentation, with an eye towards identifying thresholds. 4. Multiple models will be tested following data collection in 2009 that will investigate the relationship between management activities and the context of specific sites, such as spatial context, size, connectivity, plant diversity, plant composition, floristic quality, etc. Dollars requested will leverage Southeast Nebraska Prairies Biologically Unique Landscape Management, in an adaptive framework, by: 1. Providing partial support to a UNL graduate student (the rest from Flagship funding) 2. Jump-starting adaptive management of Nebraska Legacy landscapes. (This latter goal will include a � day workshop with Nature Conservancy and Nebraska Game and Parks Commission land managers.)	None
Implementation of amphibian monitoring and adaptive management for wetland restoration evaluation.	March 2014	The project will collect the necessary data to determine what attributes constitute a successful wetland restoration by assessing herpetofauna (primarily amphibians) as indicators of wetland quality. Many agencies are involved in restoring wetland and wish to create and restore wetlands that function as wetlands should. Amphibian recruitment and occupancy can provide guidance as to which restorations and management actions are successful. The models built for amphibian occupancy and recruitment will suggest ways to optimize restorations. The monitoring program will focus within eco-regional boundaries and will tightly linking monitoring with hypothesis testing in an adaptive framework. We will treat those models as hypotheses, and they will be placed at-risk in ongoing and future restoration activities. The work will be conducted in Nebraska and Kansas. We expect the data will provide insight into the health of amphibian and turtle communities, and therefore an estimation of overall success of wetland restorations, by allowing: 1) the estimation of breeding populations associated with each wetland, 2) the evaluation of the individual wetland's ability to support successful reproduction (as estimated by the number of metamorphosed juveniles leaving the wetland), 3) a measure (abundance) to use in comparing wetlands and wetland types using vegetative and environmental correlations, and 4) an eventual evaluation of the restoration/mitigation project's success based upon the recruitment of adults back into the breeding population that had originally been marked as juveniles at the site. II. Objectives. Wetland managers will be able to use the resulting data to understand changes in amphibian species' presence and community composition: 1) following ongoing restoration activities, 2) following other planned or unplanned changes in landuse or landcover, 3) in relation to the spatial connectivity of wetlands, and 4) in relation to adjacent landuse and landcover. The resulting models will guide managers in planning future restorations and for adaptive management of existing restorations. III. Tasks 1) Occupancy modeling will be conducted on four restored wetlands along the Missouri south of Omaha, Nebraska, and in Kansas. i) Amphibian call surveys will be conducted to determine occupancy rates by monitoring broad-scale patterns in amphibian presence or absence in restored wetlands along the Missouri River. Amphibian monitoring will quantify their occurrence and recruitment at existing wetland mitigation sites. Surveys will account for the fact that the ability to detect amphibian species varies across time, species and wetland habitats. ii) Protocols that have been extensively used across the USA will be used, and program PRESENCE will be utilized to determine occupancy rates for different species in different wetland habitats.

Northern Pearl Dace population demographics in Sandhills Ecoregion streams	December 2023	Quantified evidence of changes to population demographics of small-bodied stream fishes stemming from habitat modification is limited. In order to sustain populations of at risk species through habitat rehabilitation, information is needed regarding demographic responses including survival and movement among the mosaic of habitat patches present in stream systems. A collaborative study with the Nebraska Game and Parks Commission was initiated to assess population demographic response of Northern Pearl Dace to stream channelization in the Nebraska Sandhills Ecoregion. This work may benefit decisions regarding needs for habitat rehabilitation within agriculture-dominated landscapes as well as inform species status assessments within State Wildlife Action Plans.

Sampling efficiency assessment for Silver Carp and Bighead Carp in Nebraska mid-order streams and rivers	March 2025	Currently, eDNA is being used to investigate the distribution of invasive carp among lotic systems in Nebraska. However, attempts to verify eDNA results via live-fish collection have seen limited success due in part to limited understanding life-stage specific habitat use within prairie systems and the sampling methods to collect individuals effectively among different habitat types. Therefore, the study objectives of this project are to: (1) investigate sampling methods (i.e., towed trawls, various net configurations, and different electrofishing methods, etc.) that can effectively sample the invasive carp population, and (2) devise a sampling protocol for use in prairie systems that can target different life-stages of invasive carp populations. Such a protocol can be used to inform information gaps based on desired management objectives including documenting presence, assessing demographic rates, and/or eradication efforts. We will employ multiple gear-types including trawls, nets, and tow-barge electrofishing. Sampling efforts will occur spring, summer, and fall starting in 2023 and continuing into 2024. We will focus sampling efforts in mid-order prairie streams and rivers that are tributaries to the Missouri River and the Platte River in Nebraska. Streams and systems may include the Blue River, Nemaha Rivers, and Papillion Creek, along the Missouri River. Streams and systems may include the Salt Creek, Elkhorn River, Shell Creek, and Loup River along the Platte River. We will use information from eDNA results to direct sampling to locations with both positive and negative results for presence of invasive carp. Lower reaches of these systems may be accessible by boats using traditional sampling gears. We will sample river and stream reaches higher in the watersheds where traditional methods are not easily employed.

As grassland bird species are experiencing the sharpest declines of avifauna guilds, evaluations of tolerance levels to woody encroachment of grasslands will provide valuable information to guide conservation and restoration efforts.<br> <br>Through our research we aim to (1) evaluate the response of grassland birds to eastern red cedar removal, (2) evaluate changes in grassland bird communities and abundance among grassland patches at different stages of successional change, (3) inform best management practices to provide guidance on eastern red cedar removal and management, and (4) develop a monitoring protype to evaluate grassland bird response to woody cover management. We are parting with U.S. Fish and Wildlife Service, Rainwater Basin Joint Venture, Nebraska Game and Parks Commission, Natural Resources Conservation Service, and University of Nebraska-Lincoln.
Diverse portfolios: investing in tributaries for restoration of large river fishes in the 1 Anthropocene	December 2023	Human-induced changes to large Anthropocene rivers requires engagement of diverse stakeholders across a broad range of sociopolitical boundaries and balancing multiple objectives. Competing objectives often constrain options for ecological restoration of large rivers and subsequent conservation of native fishes. Fewer competing objectives may exist in a subset of tributaries than in large mainstem rivers. Further, tributaries contribute toward building a “portfolio” of river ecosystem assets through physical and biological processes that may present opportunities to enhance the resilience of large river fishes. Our goal is to review roles of tributaries in enhancing mainstem large river fish populations. We present case histories from two greatly altered and distinct large-river tributary systems that highlight how tributaries contribute four portfolio assets to support large-river fish populations: 1) habitat diversity, 2) connectivity, 3) ecological asynchrony, and 4) density-dependent processes. Finally, we identify future research directions to advance our understanding of tributary roles and inform conservation actions.

Evaluating reproduction, harvest, timing of season, connectivity, and spatial ecology of wild turkeys in Nebraska	December 2026	Wild turkeys are an important game species in Nebraska and across the United States of America. Managers and hunters have reported declines in the number of wild turkeys in Nebraska, similar to declines in other states and regions. Though specific causes of the declines have not been identified, most populations have reported low productivity (e.g., nest success, brood survival), but other causes also may exist. To reverse this decline, state wildlife agencies have reduced wild turkey bag limits and prioritized habitat management efforts to increase recruitment and adult female survival in the breeding season. These efforts have slowed wild turkey population declines across the country, but populations continue to decrease in certain areas, suggesting there are other site-specific factors affecting growth rates (e.g., landcover availability, brood and hen survival). Knowledge of ecology and population dynamics at local scales is needed to understand the causes of decline and inform conservation efforts in statewide and nationwide efforts to reduce (and ultimately reverse) current population trends. <br> <br>We are applying a multifaceted approach to examine the ecology and population dynamics of wild turkeys in Nebraska and specifically aim to: (1) estimate annual reproductive parameters, (2) determine space use and habitat selection of males and females, (3) examine the influence of habitat patch connectivity on effective dispersal (gene flow), (4) estimate survival and harvest rates, (5) evaluate the influence of male social status on patterns of parentage in clutches, and (6) describe gobbling activity. We are partnering with University of Georgia, Nebraska Game and Parks Commission, and Nebraska Chapter of The National Wild Turkey Federation for field data collection.

Understanding landscape constraints on local management decisions	December 2013	Throughout the Great Plains the structure and function of grassland and farmland wildlife communities are increasingly threatened by urbanization and the intensification of agricultural production. Even in areas managed exclusively for wildlife, responses to habitat enhancement is often less than predicted and less than desired by managers and the public. Given the incredible costs of wildlife enhancement projects, understanding why populations and communities fail to respond to apparently suitable habitat improvements is imperative to not only sustaining wildlife populations, but ensuring public support for wildlife programs. Traditionally, assessment of wildlife population responses to habitat improvements are focused on local habitat attributes; however, as habitats are increasingly isolated it is becoming obvious that factors beyond local vegetation and resource distribution may play a role in where species are located or the productivity of local populations. We are working to examine how the availability of suitable habitat across a landscape constrains or facilitates local population responses to grassland bird habitat enhancement programs. To this end we are developing models that relate the distribution and abundance of grassland birds to the availability and suitability of habitats across various spatial scales. By understanding how multi-scalar landscape parameters influence local populations we can betters understand how to successfully manage species and appropriate research, monitoring and management efforts. This research will assist managers and conservation professionals within federal, state, and nongovernmental organizations concerned with the management of grassland communities and protecting grassland bird species.

Migratory shorebird habitat decisions across spatial scales	December 2013	Wetland ecosystems function as important stopover habitats for migratory birds and add significantly to local and regional biodiversity. These ecosystems are increasingly threatened by climate change and the potential synergistic effects of increasing demand for water and invasion by exotic species. We are working to examine the effects of climate and land use change on bird populations and their wetland habitats in the Prairie Pothole Region (PPR) of North America by examining the linkages between climate, hydrology, and the biological factors that influence riparian and wetland ecosystem resilience and migratory bird communities. To this end we are developing multi-spatial models that relate habitat decisions of migratory shorebirds to annual and seasonal changes in water resources, and the phenology and growth of wetland plants. By exploring effects of altered climate and habitat conditions on wetland-dependent birds using a holistic approach that incorporates both top-down and bottom-up constraints, we will better predict changes in wetland ecosystems and responses of migratory birds to those changes. This research will assist managers and conservation professionals within federal, state, and nongovernmental organizations concerned with protecting migratory bird species and managing critical wetland habitats.

Characterization of Rainbow Trout and Brown Trout Below the Little Red River Tailwater	June 2025	The Arkansas Game and Fish Commission (AGFC) and the U.S. Fish and Wildlife Service created trout fisheries in the tailwater of the dam constructed on the Little Red River which created the Greers Ferry Reservoir. There is a put and take Rainbow Trout fishery and a naturalized Brown Trout population in the tailwater below the dam. Rainbow Trout stocking occurs throughout the tailwater down as far as the Monaghan/Womack Access (MWA). The section of the Little Red River below the MWA does not routinely receive stocked Rainbow Trout. Quantified information regarding the population characteristics for Rainbow Trout and Brown Trout below the MWA and the extent to which this river section of interest consists of transient or permanent residents is limited. Any future management actions would benefit from the empirical data regarding both Rainbow Trout and Brown Trout from the section of the Little Red River below the MWA. Hence, there is a need for characterization of the two trout species in that section of the river. Furthermore, thermal dynamics of the Little Red River below the MWA would influence trout growth and survival. Hence there is also a need to understand the relationship between dam releases, air temperatures and water temperatures in the portions of the Little Red River above as well as below the MWA. However, water temperature data from this section of the river and interannual changes in thermal habitat availability below the MWA are nonexistent.	There exists a need to understand basic population demographics of Rainbow Trout and Brown Trout below the current management boundaries for trout within the Little Red River, Arkansas. Further, basic information regarding water temperature suitability for sustaining trout populations within the Little Red Tailwater is needed. This project is a collaboration between the Arkansas Game and Fish Commission, the University of Arkansas at Pine Bluff, and the Nebraska Cooperative Fish and Wildlife Research Unit. Decisions regarding trout management boundaries and water releases to maintain adequate water temperatures will results from this research.
Brown Trout Movement in Little Red River tailwater	June 2025	The population of Brown Trout below the Greers Ferry dam on the Little Red River (Greers Ferry Tailwater) is unique among trout populations in Arkansas. It is the only self-sustaining trout fishery in the State. While other trout fisheries in tailwaters below dams on the White River and its tributaries require stocking to sustain the fishery, no Brown Trout stocking is required in the Greers Ferry tailwater. This unique situation calls for a considered approach to managing this Brown Trout fishery, because of the inability to influence the fishery by varying stocking levels. Management of this Brown Trout fishery requires some understanding of spawning within the tailwater. This issue was the subject of a previous research project. Trout are managed in the Greers Ferry tailwater from the dam to the Monaghan/Womack Access (MWA) at the Hwy 305 bridge, east of Pangburn, Arkansas (~48 km or 30 miles). The magnitude and persistence of a Brown Trout fishery below the MWA is unclear. Data on trout movement within this section of the Little Red River or between this section and the tailwater above the MWA do not exist. This data gap regarding Brown Trout movement patterns will be addressed by this proposed project.	The magnitude and persistence of a Brown Trout fishery below the trout management zone in the Little Red River is unclear. Data on trout movement within this section of the Little Red River or between this section and the tailwater above do not exist. As such, it is unknown what levels of protection are needed for trout that readily move among river segments. This data gap regarding Brown Trout movement patterns will be addressed by this proposed project. This project is a partnership between the Arkansas Game and Fish Commission, University of Arkansas at Pine Bluff, and the Nebraska Cooperative Fish and Wildlife Research Unit. Decisions regarding extension of trout management boundaries will result from this work.
Multi-scale habitat needs of at-risk fishes in Nebraska	February 2025	The distribution and abundance of prairie-river fishes is maintained through demographic processes that occur over multiple scales embedded within a habitat matrix. Degradation of the habitat matrix in rivers, however, can limit completion of demographic processes (e.g., recruitment and movement) that may exacerbate the time for recolonization or permanently reduce their distribution and abundance. A major limitation exists, however, due to a lack of understanding of fish-habitat relationships at multiple spatial and temporal scales for many SGCN. A prominent question that remains unanswered includes 1) what habitat features at different spatial scales promote the presence of a species? This research is being conducted with support from and in collaboration with the Nebraska Game and Parks Commission. This study will set the stage for future work assessing fish-habitat relations by identifying locations most likely to contain species of interest. Benefits from this study may also feed data into the Nebraska Conservation and Environmental Review Tool (CERT), commonly used as a review for proposed projects and potential impacts within areas of at-risk species presence.

Assessment of Silver Carp and Bighead Carp in the Platte River, Nebraska: emphasis on distribution, population demographics and reproduction	January 2024	Understanding the population characteristics and recruitment of Silver Carp and Bighead Carp within the Platte River system is imperative to prevent further expansion and mitigate the risks to human interests and the native fish communities. The study objectives of this project are to: (1) assess the prevalence of spawning, reproductive success, early recruitment, and habitat use of young-of-year Silver Carp and Bighead Carp within the lower Platte River, and (2) assess the temporal and spatial distribution and reproductive characteristics including—but not limited too—size, age at reproductive maturity and fecundity of Silver Carp and Bighead Carp populations on the Platte River and lower reaches of major tributaries of the Platte River.	Invasive Bighead Carp and Silver Carp are expanding into Great Plains rivers and limited information regarding basic population demographics exists. Information on population demographics including abundance and reproduction can highlight areas where populations are expanding and possibly contributing individuals to other aquatic systems. This project is a collaboration with the Nebraska Game and Parks Commission. This work will help direct removal efforts and aid in informing risk assessments within interior rivers of Nebraska and other Great Plains river systems.
Assessment of angler use and catch during 2022 at Sutherland Reservoir, Nebraska	March 2023	The Nebraska Public Power District is a publicly-owned utility and a political subdivision of the State of Nebraska. Its chartered service territory is vast, including all or parts of 86 of Nebraska's 93 counties. The utility works through partnerships to help serve more than an estimated 600,000 Nebraskans with retail and wholesale electric power and energy-related services. The Nebraska Public Power District owns and manages Sutherland Reservoir, a 3,000-surface-acre reservoir located three miles south of the Interstate 80 Exit at Sutherland, Nebraska, as part of its hydropower system, and the Nebraska Game and Parks Commission oversees most of the recreation areas at this reservoir. The purpose of this study is to estimate angler use and catch at Sutherland Reservoir, Nebraska, from April through October 2022. Specifically, we obtained monthly estimates of angler pressure, catch, and harvest. This information will allow the Nebraska Public Power District to evaluate angler use and influence of the fishery at Sutherland Reservoir, and is a required component of its hydropower operating license.	Sutherland Reservoir (1,220 hectares) is the first canal reservoir downstream from Lake McConaughy and is utilized for the cooling of Nebraska Public Power District’s (NPPD) Gerald Gentleman Station. Permitting requires ongoing monitoring of activities, including recreational fishing. The purpose of this study is to estimate angler use and catch of Sutherland Reservoir, Nebraska, during 2022. This project is a collaboration of researchers across multiple agencies and includes the University of Nebraska—Lincoln and the Nebraska Public Power District. Information gained on angler behavior will be important for increased effectiveness of fishery management, as well as increased effectiveness of plant operations.
Pallid Sturgeon biology in the Platte River and its tributaries	December 2026	The Pallid Sturgeon is a U.S. Threatened species that primarily inhabits the Missouri River and lower Mississippi rivers. Ongoing work in the mainstems of large rivers has provided much critical information regarding the biology and ecology of the species. However, substantial knowledge gaps exist regarding the species use and dependence on tributaries of the mainstem Missouri and lower Mississippi rivers. This project is intended to assess habitat use and availability for Pallid Sturgeon in the Platte River, Nebraska. Additionally, this project will assess the occurrence of spawning behavior potential spawning success within the Platte River, Nebraska.	The Pallid Sturgeon is a U.S. threatened species that primarily inhabits the Missouri and lower Mississippi rivers. Extensive habitat alteration with large mainstem rivers has greatly reduced reproduction and recruitment of Pallid Sturgeon. Tributaries may play a role in fulfilling life stage needs of Pallid Sturgeon and may be particularly important for spawning and recruitment of young. However, limited information exists regarding the use and propensity of reproduction within tributary systems. The project is a collaboration among multiple private and government agencies including the Headwaters Corporation and Nebraska Game and Parks Commission. Reducing the information gaps regarding reproduction, recruitment, and habitat use in tributary systems by Pallid Sturgeon will directly influence decisions regarding monitoring efforts and habitat protections.
Stream-fish population and community characteristics within Nebraska, USA	August 2022	The objectives of this study are 1) to collect and summarize fish-sample data from across stream systems within Nebraska, USA, 2) to identify information gaps regarding spatial and temporal scope of different stream-fish sampling protocols among stream systems in Nebraska, USA, and 3) to assess functional trait diversity in stream-fish communities among ecoregions within Nebraska, USA.	Collecting ecological data at broad spatial and temporal scales can be limited due to cost and time constraints. Combining data from multiple sources across spatial scales and through time is often necessary to ask questions regarding drivers of population distributions. A comprehensive database of occurrences of stream fishes and landscape variables may provide insight into drivers of population distributions and community characteristics needed to inform conservation status. The Nebraska Game and Parks Commission is a partner on this project. The development of habitat and species distribution models from existing datasets may reduce the knowledge gap regarding fish-habitat relations of stream fishes and direct future conservation efforts.
Investigating hybridization between the declining Gray-headed Chickadee and a recent colonizer, the Boreal Chickadee	September 2024	Gray-headed chickadees were historically common in Alaska and northwestern Canada and in recent years populations have been extirpated (or are in decline) and replaced with boreal chickadees. There is insufficient information to identify threats to Gray-headed Chickadees in North America with confidence. Two mechanisms are thought to be playing a role in the decline of gray headed chickadees – interspecific competition and genetic swamping. This project is a collaboration across multiple agencies including Fish and Wildlife Service, Alaska Department of Fish and Game, National Park Service, and Canadian Wildlife Service. Understanding what role, if any, hybridization has on the decline of the Gray-headed Chickadee is an important step in defining and prioritizing appropriate and effective conservation recovery actions.

Assessment of angler satisfaction in the mainstem Missouri River, Nebraska	December 2023	Satisfaction, an attitude-like judgment of an event based on pre-event expectations, of recreational participants is important to natural resource managers. A growing concern throughout freshwater ecosystems in North America is the negative effects of aquatic invasive species on water-based recreational activities. However, positive effects of aquatic invasive species to on water-based recreational activities are possible.<br><br>The American paddlefish is a popular target among fishers on the Missouri River, which has thriving populations of bighead carp and silver carp (collectively referred to as “bigheaded carp”). Bigheaded carp, native to Asia, are invasive species in North America. It is likely that multiple ecological and sociological factors contribute to satisfaction of fishers targeting American paddlefish in the Missouri River.<br><br>To understand the influence of bigheaded carp on paddlefish-fishers’ satisfactions, we are quantifying fishers’ expectations and outcomes during archery and snagging seasons on two temporal scales—day and season. Our <i>a priori </i>prediction was that the presence of bigheaded carp would positively influence satisfactions of fishers during archery season (by providing additional opportunities to shoot fish) and negatively influence satisfactions of fishers during snagging season (by increasing work, via bycatch of bigheaded carp, required to harvest an American paddlefish). Preliminary results are somewhat consistent with our prediction. The presence of bigheaded carp did enhance satisfactions of fishers during archer season, but did not diminish satisfactions of fishers during snagging season.	Abundances of invasive carps (Bighead Carp, Silver Carp) have steadily increased during the past several decades in a reach of the Missouri River below Gavins Point Dam, anecdotally negatively affecting anglers’ satisfaction. As important sources of revenue, anglers’ opinions and satisfactions matter to natural resources agencies. A multipronged approach ((in-person creel surveys, mail surveys) to quantify anglers’ expectations as a basis for understanding stated satisfactions. The project is a collaboration of researchers across multiple agencies and includes the U.S. Fish and Wildlife Service, the Nebraska Game and Parks Commission, The Kansas Department of Wildlife and Parks, and the South Dakota Game, Fish and Parks. Data and information will be gather that will aid in management and future regulations of paddlefish in this reach of the Missouri River.

Monitoring, Mapping and Risk Assessment and Management of Invasive Species in Nebraska - Part II	December 2024	The Nebraska Invasive Species Council focuses on early detection, prevention and management of invasive species within the state of Nebraska. The members of this council are committed to minimizing the harmful effects of invasive species, with an ultimate goal of promoting healthy landscapes and healthy people. To help fulfill this commitment, Allison Zach served as the Coordinator for the Nebraska Invasive Species Council from September 2013 through March 2023. In this capacity, Allison served as a liaison with Nebraska’s Governor and State Legislature. Allison developed and provided invasive species outreach and education to Nebraska resource agencies, individual stakeholders, educators and the general public. She served on the North American Invasive Species Management Association (NAISMA) Board, and was the NAISMA Play, Clean, Go committee Chair.<br><br> The Nebraska Invasive Species Council develops management tools including an invasive species adaptive management plan, a risk analysis for high-risk invasive species in Nebraska, a multi-agency prevention protocol for preventing the spread of invasive species (terrestrial and aquatic), and identification of invasive species introduction pathways. The Council created a 2-sided outreach card during 2020 and updated its adaptive management during 2021. The Council’s website has a reporting tool; concerned citizens have identified new infestations of zebra mussels and other invasive species—these reports are referred to an appropriate invasive species expert for investigation and guidance.	Invasive species are a threat to native species and a threat to ecosystem services. Invasive species exist in many forms, and thus, jurisdictions exist across a multitude of management entities. Coordination across these entities is important. This project is a collaboration with Nebraska Game and Parks Commission to continue funding a position for a coordinator among the state and federal entities that interface with invasive species within the state of Nebraska. The coordinator facilitates risk analyses, encourages collaboration on management recommendations, and ensures information sharing among stakeholders of biological invasions.

Bat Conservation and Recovery in Nebraska and Wyoming	January 2023	There are mounting concerns for North American bats due to continuing and emerging threats from disease, habitat loss, fragmentation, and wind-energy development. Although these threats are likely to increase in severity, there is an opportunity to improve our knowledge of bat occurrence and habitat use, to learn how landscape changes affect local bat populations, and to establish regional monitoring that can inform local and national resource management decisions. This is especially true across Nebraska, which encapsulates edges of several bat species’ ranges.<br><br>We implemented the North American Bat Monitoring Program (NABat) in Nebraska to survey statewide bat species distributions and activity. Thirty-five monitoring areas were established across the state to sample with bat acoustic detectors each year, comprising about 120 sites, and involving about 100 landowners. Much of these data were collected by volunteers (citizen scientists); we were excited by our successes in building an extensive and reliable citizen science network for bat monitoring.<br><br> We documented 12 bat species during our monitoring efforts, including some that have experienced dramatic population declines in other parts of the country from the invasive fungal disease that causes white-nose syndrome. Some species we found statewide, whereas we detected other species only in certain areas of Nebraska. Overall bat activity has been generally greatest in eastern parts of the state, and least in central and southwestern parts of the state, perhaps an effect of fewer available tree roosts. Future sampling efforts could be used to gather evidence of activity changes and range expansions by these bat species.	There are mounting concerns for North American bats due to continuing and emerging threats from disease, habitat loss, fragmentation and wind turbines. In anticipation that threats are likely to increase in severity, there is an opportunity to improve the resiliency of summer habitat, to learn how changes affect local bat populations, and to establish regional monitoring that will Inform local decisions and national actions. This project is a collaboration of researchers with the Nebraska Game and Parks Commission and the Wyoming Game and Fish Department, and state and federal natural resource managers throughout the Midwest USA. This project will result in more strategic bat conservation across Wyoming and Nebraska by monitoring bat populations and by providing decision makers with decision-support tools and a conservation plan. Ultimately, managing fish, wildlife and their habitats for the enjoyment of current and future generations is the underlying foundation of this project.
Angler behavior in response to management actions on Nebraska reservoirs -- Part 3	December 2024	Recreational angling, a billion–dollar industry, is the most influential factor structuring fish populations in inland systems. Given its importance and the reliance in North America on sportspersons to fund conservation activities (i.e., the North American Model of Wildlife Conservation), natural resource agencies invest substantial resources to manage angler-fish interactions to ensure long-term sustainability. Arguably, most of our current understanding and management efforts of recreational fisheries are directed toward larger fisheries in rural environments. These waterbodies are highly visible resources and often attract many anglers from long distances. However, we know less about anglers in urban environments and their behaviors locally at smaller waterbodies. It is important for us to understand angler behavior in metropolitan areas because the landscape is becoming more urbanized. We anticipate that urban fisheries function differently than their rural counterparts.<br><br>Project goals are to understand 1) the participation patterns of anglers on multiple spatial and temporal scales; 2) how participation patterns of anglers’ influence fish populations and associated communities; 3) how management actions influence angler participation patterns and, in turn, fish communities; and 4) interactions and feedback mechanisms between and among angler groups and fish communities. The project currently has eight study components.<br><br>1. Omaha Angler Survey. Anglers were interviewed April through October on-site at Prairie Queen, Schwer, Halleck, and Standing Bear during 2019, at Benson, Flanagan, Fontenelle, and Walnut Creek during 2021, at Zorinsky, Prairie View, and Lawrence Youngman during 2022, and at Flannagan and Cunningham during 2023. These interviews are intended to add to statewide angler survey datasets that are valuable for assessing changes in angler participation, catch, and harvest. These extended datasets allow for relational assessments of changes in angling participation while considering environmental conditions and management actions on large spatiotemporal scales.<br><br>2. Omaha Angler Effort. Anglers were counted at 22 public waterbodies in the Omaha area from February 2019 through January 2020. In addition, the Nebraska Game and Parks Commission continued angler counts at 10 of the waterbodies from April 2020 through October 2020. Angler effort was highly variable with most angler effort occurring in west Omaha. Larger waterbodies typically receive the most fishing effort. Most anglers access waterbodies from the bank rather than from a boat. Half of the waterbodies surveyed receive more than 20,000 hours of angling effort; four of these waterbodies receive more than 60,000 hours, which is comparable to many large, rural fisheries in the state. Towl and Halleck receive the most angler effort per unit of area, with approximately 7,500 angler hours per acre. Angler effort generally peaked from May through July and remained low during winter months, perhaps because of poor ice conditions.<br><br>3. Omaha Recreation Survey. Recreational anglers express a variety of behaviors and specializations, making angling forecasting and management difficult. During February-March 2020, we surveyed—in collaboration with the University of Nebraska’s Bureau of Sociological Research—a subset of Omaha residents that purchased a fishing license during 2019. We used mail-surveys (email and pre-paid envelopes) to quantify demographics, behaviors, and visitation rates to Omaha metropolitan waterbodies (and other prominent Nebraska waterbodies) during 2019. Behavioral differences are evident across the Omaha area. We used these surveys to also identify sociodemographic variables that might be used to predict days spent on recreational fishing, and to identify recreational activities complementary to fishing. Participation in recreational fishing does not differ across the Omaha area, yet participation in other recreational activities (e.g., fitness and woodworking) does differ among anglers across the Omaha area. This knowledge is useful to managers, as it provides valuable insights on current angler activities and could help predict future angler activity based on demographic characteristics and landscape changes (i.e., urbanization) across a region.<br><br>4. Understanding Variation of Recreational Angler Effort. Waterbody size (i.e., surface area) accounted for 60% of the variance in angler effort across 73 Nebraska waterbodies during 2009-2019. The relationship between the size of a resource and the amount of use the respective resource receives can be utilized by natural resource managers to produce broad-scale estimations of system use, guide the allocation of management resources according to expected system use, predict how changes in system size may affect the amount of use, and highlight how different user groups may interact with systems of various sizes. For instance, utilizing the waterbody size-angler effort relationship allows us to predict that anglers exert over 4,750,000 hours of effort annually on public waterbodies in Nebraska. The relationship between waterbody size and angler effort also differs based on how anglers access the waterbody (i.e., via the bank or a boat). Boat-angler effort increases at a higher rate as waterbody size increases compared to bank-angler effort.<br><br>5. Recreational Use of Valentine National Wildlife Refuge. Valentine National Wildlife Refuge is an important social-ecological system that provides a variety of recreational opportunities for visitors. Even so, we have little understanding of the types and frequency of activities that occur on the refuge and the sociodemographic characteristics of visitors. We used 789 completed surveys (from 2,251 distributed windshield surveys; 35% response rate) to understand participation and potentials for social conflicts and ecological impacts of hunting, fishing, and wildlife watching (including touring, hiking, photography, and environmental education) groups. The fishing group was the predominate group (78%) on the refuge from July 2017 to July 2018. Social and ecological intensities varied across lake types (e.g., fishing vs. non-fishing) and seasons, highlighting intense-impact areas and periods on the refuge. Accounting for the diverse recreational activities and social and ecological intensities will allow managers of Valentine National Wildlife Refuge and other social-ecological systems the ability to concomitantly preserve ecological resources, prioritize conservation efforts, and minimize visitor conflicts.<br><br>6. Lake McConaughy Angler Survey. Lake McConaughy is an important fishery in western Nebraska. We interviewed anglers on-site during daytime hours during April-October 2022 and during nighttime hours during April-May 2022 and 2023. These interviews were in response to public concerns surrounding potential overharvest of walleye during the springtime walleye spawn, especially large individuals that are economically and ecologically important in the walleye population. The purpose of these surveys was to document the relative amounts of walleye harvested during these two periods and to document the demographics of anglers for these two periods. Catch rates of walleye for walleye-seeking anglers during April 2022 were 0.5 walleye/hour fishing during nighttime and 0.2 walleye/hour fishing during daytime.<br><br>7. Ogallala. Lake Ogallala (and its associated canal and rive) provides a unique trout fishery in western Nebraska. However, this fishery has limited resiliency toward invasions by the common carp that is established in the upstream water supply (i.e., Lake McConaughy). We surveyed anglers during 2023 to gather baseline data for use in future evaluations of management actions designed to reduce the biomass of the common carp population in Lake Ogallala.<br><br>8. Economic valuation of recreational fishing. Economic values of individual fisheries are important pieces of information, especially for prioritizing management actions and allocating limited resources. We teamed up with Dr. Max Melstrom, an economics professor at Loyola University Chicago, to develop a model to assign economic values for public reservoirs throughout Nebraska.	Recreational fishing is the most influential factor structuring fish populations, especially in inland systems with intensive fishing pressure. Even so, inland fishery biologists rarely incorporate spatial and temporal patterns into management strategies, possibly because little is understood about angler decisions to participate in the sport. This project is a collaboration of researchers across multiple agencies and includes the University of Nebraska—Lincoln and the Nebraska Game and Parks Commission. Information gained on angler behavior will be important for increased effectiveness of fishery management, as well as increased effectiveness of angler recruitment and retention activities.
Working with rural students to document swift fox on Nebraska Ranches	July 2018	The loss and alteration of native grasslands has resulted in significant reductions in habitat availability for grassland obligate species such as the swift fox (Vulpes velox). Identified as a Tier 1 at–risk species, swift fox are estimated to occupy 21% of their historic range, but the exact distribution and relative health of swift fox populations in Nebraska remains in question. The Nebraska Game and Parks Commission, the Nebraska Department of Roads, and the U.S. Forest Service, in collaboration with the University of Nebraska–Lincoln (UNL) and Chadron State College (CSC) have begun an effort to document the occurrence of swift fox and identify the anthropogenic and ecological factors that limit their distribution. However, in a state which is 97% privately owned, such an endeavor is extremely challenging because access to land ultimately limits inference about swift fox populations and thereby management efficacy. Using a unique approach which incorporates landowners in the conservation process we are sending undergraduate students back to their family ranches to survey for swift fox. Many students in range management, wildlife biology, and similar conservation majors at CSC and UNL are from working ranches in Western Nebraska, which presents us with a unique opportunity to allow students to realize their conservation interests on their family lands and assist NGPC, NDOR, and USFS in facilitating the conservation of a Tier 1 species. Our project is training students and working with them to set camera ‘traps’ on their family lands each spring and fall. By surveying for swift fox on private lands we are adding significantly to our understanding of what is limiting this rare species in Nebraska; moreover, because camera traps attract a multitude of species we are documenting and thereby aiding in the management of other species of conservation concern here in Nebraska.

Use and satisfaction of public hunting opportunities	December 2018	The retention and recruitment of hunters is of increasing concern to wildlife management agencies nationwide. A lack of access to quality hunting opportunities is often deemed as the primary reason why people quit hunting. In an effort to provide hunting opportunities for their constituency, the Nebraska Game and Parks Commission invests considerable time and resources into the development and management of public Wildlife Management Areas and private lands open to public access through the Open Fields and Waters Program. Although investment in these programs is assumed to fulfill the needs of the hunting community, evaluating the use of public or private land by hunters, and their overall satisfaction with the hunting experience is challenging. Currently, the majority of hunter participation, satisfaction, and harvest data are collected at coarse spatial and temporal scales, through post-season surveys. Unfortunately, this data does not provide the preferred resolution needed to appropriately manage individual Wildlife Management Areas or Open Fields and Waters sites. Moreover, it does not allow managers to assess the value of their investment in particular lands. The effect of hunting and hunter participation on wildlife populations, hunter recruitment and retention, and local economies is likely acting at multiple scales that are currently not considered when managing wildlife resources. Given the limited resources available for wildlife management, managers need a better understanding of hunter participation at the scales for which management actions occur if they are expected to manage lands appropriately. From 2014-2017 we worked with the Nebraska Game and Parks Commission to assess recreational activities on more than 500 properties from eight focal areas spread across Nebraska. In total, we conducted more than 110,000 point-surveys that identified in excess of 11,000 cars. We also interviewed more than 7,000 users of publically accessible lands in Nebraska. Users represented an array of outdoor enthusiasts from 44 different states, with upwards of 80% of the fall users being hunters. We are currently analyzing the data to understand how users of publically accessible lands distribute on the landscape in the hopes of helping managers identify effective strategies for providing opportunities for outdoor enthusiasts in Nebraska.

Climatic constraints on bobwhite quail populations along their northern extent	December 2019	Northern bobwhite quail (Colinus virginianus) are among the most popular game birds in North America; however, the loss of suitable habitat has led to precipitous population declines throughout their range. With significant grassland and farmland habitats, Nebraska has the potential to maintain viable quail populations, but due to the climatic conditions imposed by harsh winters and periodic wet springs, quail populations in Nebraska tend to be highly variable from year to year. Local habitat management may be capable of overcoming some environmental constraints, but effective management strategies necessitate a comprehensive understanding of the impacts of large scale climatic conditions on Nebraska’s quail resources. Although there are numerous studies focused on water constraints for quail populations in arid environments, the role of climatic conditions in driving quail populations in traditional temperate environments remains limited with much of the research conducted when the landscape was more conducive to facilitating population rebounds after severe weather events. Given the current agricultural paradigm, and predicted changes in climatic conditions, it remains unknown whether effective management implementation can lead to reliable quail populations and facilitate long-term stability in hunter engagement, satisfaction, and participation. In a first step to addressing this issue, we propose to identify the mechanism by which climatic conditions impact quail and the means by which management may overcome climatic constraints. Working with Nebraska Game and Parks Commission we aim to improve our understanding of how severe climatic events (e.g., snow storms, spring rains) alter quail physiology and behavioral decisions to impact population stability in Nebraska and to further develop management strategies aimed at offsetting these costs. Using an individualistic approach that considers the inherent trade-offs in life history, physiological, and behavioral expression, we hope to identify key constrains in population growth and management strategies that many ameliorate population cycles.

Range and Habitat Usage of Northern Long-Eared Bats in Nebraska	August 2018	The listing of the Northern Long-Eared Bat (NLEB) as threatened under the U.S. Endangered Species Act in spring of 2015 highlighted the need for increased understanding of the ecology of this species within Nebraska. This project aims to evaluate distribution and habitat usage of the Northern Long-Eared bat throughout the state. This critical information will allow managers and biologists to focus future conservation efforts on areas that will have the greatest positive impact. If federal restrictions are increased in the future due to projected population declines, this work will also potentially limit intensive and costly consultation with the U.S. Fish & Wildlife Service to only areas where NLEB is likely to occur, i.e., our results will result in better maps of habitat and geographic range. To achieve our objectives, this project implemented a two-stage process over the course of two field seasons. The first stage acoustically sampled the entire state to better define the geographic distribution of the species. We completed this sampling in August of 2015 and used this data to predict occupancy of the Northern Long-Eared bat across the state and to understand the landscape variables associated with occurrence of the species. In part two of the project, I intensively sampled five locations within NLEB’s Nebraska range to determine stand-level habitat usage. Between May and August of 2016, we deployed forty-six paired bat detectors simultaneously at each of the randomly selected locations. This resulted in >1,500 recordings nights with NLEB being detected at all locations. Combined with site measurements and remotely sensed data sources, this data will provide insight into the factors that contribute to occupancy as well as detection probability of the species. The final stage of the project was a quantitative meta-analysis of northern long-eared bat roosting studies across North America. This study enabled range-wide conclusions on roost tree characteristics selected for by the Northern Long-eared Bat.	The Northern Long Eared bat is endangered and declining, but its range and habitat use in Nebraska is poorly known. Because Nebraska is at the range of its geographic distribution, habitat use may differ from more typical habitat to the east. Understanding this species habitat use and distribution will help management in Nebraska and reduce conflicts with other interests. This project is a collaboration with the Nebraska Department of Transportation and the Nebraska Game and Parks Commission. Habitat models and geographic distribution resulting from this project will improve this species management and inform managers when mitigation activities might be needed.
Rainwater Basin Joint Venture Science	June 2019	The Rainwater Basin Joint Venture’s (RWBJV) mission includes science–based conservation efforts for all priority bird habitats throughout Nebraska’s mixed–grass prairie region. The Management Board of the RWBJV is committed to implementing the U.S. Fish and Wildlife Service’s Strategic Habitat Conservation model. This science–based model requires a commitment of resources and time to develop a strong biological foundation for delivering conservation planning and designing research and monitoring efforts. To fulfill this commitment, the University of Nebraska–Lincoln hired Dana Varner as the RWBJV Science Coordinator in October 2014. This position is the product of a partnership between the RWBJV, the Nebraska Cooperative Fish and Wildlife Unit, and the University of Nebraska–Lincoln School of Natural Resources, which provides office space and support in Lincoln. Funding for the position is provided by the RWBJV.	The Rainwater Basins are a critical wetland complex, providing habitat for millions of migratory waterfowl each year. Several management and research agencies work in the Basins. This project is a partnership between the Nebraska Coop Unit, the Nebraska Game and Parks Commission and the Rainwater Basin Joint Venture. This project enhances communication and coordination amongst these three principals, towards better management of the Basins.
National Science Foundation Research Traineeship (NRT) Program	September 2022	This National Science Foundation Research Traineeship (NRT) award to the University of Nebraska – Lincoln, establishes a new graduate training program that focuses upon understanding the resilience of agricultural systems. Nebraska hosts one of the world’s most productive and efficient agricultural systems, the Platte River Basin. Like most agricultural systems characterized by high productivity and efficiency, its resilience to change is unknown. This training program builds upon strengths at the University of Nebraska, and joins the disciplines of agronomy, natural resources, computer sciences and engineering with policy studies, to enhance the resilience of agricultural landscapes to global – and local – change. Interdisciplinary training for Master’s and Ph.D. students will enhance the type of team-building needed to address today’s food, energy, and water problems, and trainees will engage with external partners from the agricultural industry, from state and federal government, and NGO’s that have an interest and stake in maintaining productive agricultural systems. The traineeship program anticipates preparing ~50 trainees (25 Ph.D. and 25 Master’s), including 23 funded trainees (9 Ph.D., 14 Master’s), with a focus on hands-on experiences between the university and its industry and agency partners. Trainees will focus on key aspects of agricultural resilience specific to their interests, while receiving broad training in resilience theory as applied to working agricultural landscapes. This training will help develop a workforce and agricultural industry better capable of managing future demands on food, energy, and water systems. Currently the program is supporting ten students. This NRT program will focus on understanding resilience in water-stressed and energy-demanding agricultural landscapes and will utilize resilience and panarchy theory, adaptive management, novel sensing technologies and modeling, and policy interventions. Such training is rare in graduate programs in the United States, but is required to prepare the next generation of natural resource scientists, producers, managers, engineers, and policymakers to better respond to the challenges created by increasing demands for diminishing and interconnected resources and the need to maintain and build resilience in stressed watersheds. The University of Nebraska is recognized as a global leader in water and agricultural sciences; this NRT will explicitly integrate these disciplines. This NRT will train students in interdisciplinary science at the nexus of theory and application, and the intersection of sometimes completing, sometimes complementary endpoints of food, water, and energy – and ecosystem services – sustainability. In addition, this NRT will serve as the innovative foundation for a permanent interdisciplinary graduate program that will create a novel education program in the resilience of agro-ecosystems and ensure students, academic programs, local-to-federal agencies, and the private sector engage in building and preserving natural and agricultural ecosystems to meet local-to-global demands of water (in quantity and quality), clean energy, food, and ecosystem services. Moreover, this NRT will develop cross-disciplinary training for multidisciplinary cohorts of graduate students focused on the complex and intertwined ecological, technical, and societal systems involved in managing resilient water resources in the 21st century, in complex landscape managed for agricultural production. Further, the program will help develop innovative tools for data collection, analytics, and synthesis for decision support, management, and restoration of water-stressed agricultural systems within local-to international contexts. The program is designed to encourage the development and implementation of bold, new potentially transformative models for STEM graduate education training. The Traineeship Track is dedicated to effective training of STEM graduate students in high priority interdisciplinary research areas, through comprehensive traineeship models that are innovative, evidence-based, and aligned with changing workforce and research needs.	Understanding the components of resilience in landscapes is critical given the rapid speed of landuse and other global changes. Understanding the factors of resilience will allow for the management of landscapes such that they can absorb disturbance with out changing "state". This project is funded by the US National Science Foundation and includes collaboration of many state and federal agencies, including the Nebraska Game and Parks Commission, the US Fish and Wildlife Service, and the Nature Conservancy. The project focuses on training of students, and will enable the creation of a multi-disciplinary work force informed by current theory and best management practices.
Novel Ecological Uses for Unmanned Aerial Vehicle-UAVs	July 2019	We have established a team of ecologists, computer scientists, and engineers who have been exploring novel applications of Unmanned Aerial Vehicle (UAV) technology to ecological challenges. A primary application is the use of UAVs to remotely ignite controlled burns to help with management of grasslands, including the reduction of woody invasive species such as eastern red cedar. This particular line of work has led to the development of a prototype UAV. Prototypes have been utilized to initiate internal ignitions in a large prescribed fire in the Loess Canyons of Nebraska, and a very public burn at the National Park Services Homestead National Monument of America. Both applications were successful, and funding has been secured to continue to develop this technology. Additional uses include the development of a module to remotely sample invasive zebra mussel veligers (larvae). This application was successfully deployed for the first time at Offutt Lake, Offutt Air Force Base, Nebraska. In this case, as with prescribed fire, the development of UAV technology is enabling both more efficient and safe sampling (or burning), where safety is paramount and logistical constraints limit effort.	Both wildfire and prescribed fires present dangers to humans, but are natural disturbance processes critical for maintaining and managing ecosystems. A safer methods of ignition could allow greater use of fire in management, and safe human lives. With funding from the National Science Foundation, and collaboration with the Nebraska Game and Parks Commission and agronomists, computer scientists and engineers, we developed an UAV to remotely ignite prescribed fires under a variety of conditions.
Managing Red Cedar Invasions of Nebraska Grasslands -Part II	December 2020	Juniper expansion is an important issue, especially in the Great Plains, because ecosystem service provisioning is altered when grasslands are invaded by juniper. However, an assessment of the impacts juniper invasion has on ecosystem service provisioning is lacking. A central aim of this thesis research is to synthesize the impacts of juniper invasion on grassland ecosystem services. This synthesis will then be contrasted against: - How Nebraskan’s value ecosystem services - How other invasive species in grasslands alter ecosystem service provisioning - How natural resource professionals perceive the impact of juniper invasion relative to other invasive species	Red cedar is an invasive species that degrades grassland habitat and reduces rangeland productivity. Red cedar is responsible for an ongoing biome-level regime shift across the Great Plains. This project is a collaboration with agronomists and with the Nebraska Game and Parks Commission. Products will focus on methods to reduce cedar spread, minimize its impacts, and better restore degraded habitats.
Managing Red Cedar Invasion of Nebraska Grasslands- Part I	January 2021	Eastern Redcedar is the most rapidly expanding woody plant species in the Great Plains and is now recognized as the number one threat to Nebraska’s rangelands by the Nebraska Conservation Roundtable. The impacts of redcedar invasion in grasslands are wide-ranging, including reducing grassland bird diversity and abundance, decreasing livestock production by 75%, reducing small mammal and insect diversity, and costing Nebraska Public Schools over $2,440,000 from 2006-2016. The objective of this grant is to assess the vulnerability of Nebraska’s grasslands to redcedar invasion, and develop predictive tools that enhance the potential to implement landscape interventions that (1) prevent the spread of redcedar trees or (2) restore degraded wildlife habitat following transformation to a redcedar-dominated state.	Red cedar is an invasive species that degrades grassland habitat and reduces rangeland productivity. Red cedar is responsible for an ongoing biome-level regime shift across the Great Plains. This project is a collaboration with agronomists and with the Nebraska Game and Parks Commission. Products will focus on methods to reduce cedar spread, minimize its impacts, and better restore degraded habitats.
Invasion, Cost-share, and Private Landowners: Resolving the Challenges of Scale with Managing Juniperus Virginiana on Nebraska's Rangelands	December 2018	With the rise of globalization, the spread of invasive species has become increasingly prevalent and problematic. A characteristic of many biological invasions is a period of rapid population growth following introduction; management and control is most likely to be successful if it occurs prior to that period of rapid growth. By its scientific name, Juniperus virginiana or commonly known as Eastern Redcedar (ERC) is a woody species currently invading the Great Plains of the USA. Although it is native to Nebraska, it is spreading into grasslands and rangelands where it was not historically present and has the potential to seriously disrupt the local economy, including cattle production. Cedar can be controlled via regular burning to grasslands, which removes woody brush and revitalizes native grasses, however, public opinion of prescribed fire is uncertain. Because so much of Nebraska is privately owned, it is critical that the public understands the seriousness of the ecological and economic costs of cedar invasion, and the importance of properly managing both private and public lands. Cost-share programs provide funding that offsets the cost of and provides technical assistance for management which improves the environment, and engaging landowners educates them on local ecological issues and solutions, potentially educating their friends and neighbors, too. Joining a cost-share program is voluntary, so to increase participation, much research has been done to determine which incentives are preferred by the majority of landowners. Although these studies have discussed the social aspect of cost-share, they overlook the ramifications of structuring a program based on landowner preferences rather than ecological science. If cost-share management is at a smaller scale than ERC invasion, management will not be successful in the long run. The purpose of this study is to understand the perceptions of Nebraskan landowners in regards to ERC and ERC management, and the ways participation-based incentives influence the scale of management of Nebraska Game and Parks Commission cost-share programs which remove ERC, to identify where these programs are succeeding at their conservation goals and where improvements can be made.	Red cedar is an invasive species that degrades grassland habitat and reduces rangeland productivity. Red cedar is responsible for an ongoing biome-level regime shift across the Great Plains. This project is a collaboration with agronomists and with the Nebraska Game and Parks Commission. Products will focus on methods to reduce cedar spread, minimize its impacts, and better restore degraded habitats.
Implementing the North American Bat Monitoring Program Through Citizen Science in Nebraska	November 2018	Bats are incredibly important to both ecosystems and humans. Their significance is demonstrated through the ecosystem services they provide, which include seed dispersal, pollination, and insect population control. Within states whose economy is largely dependent on agriculture, such as Nebraska, ecosystem services provided by bats are of particular significance. Pest control services from bats are valued between $3.7 and $53 billion dollars each year in savings for the agricultural industry. This is largely because bats are voracious predators of nocturnal insects, including significant agricultural and forest ecosystem pests. Only a handful of scientists have done extensive research on the bats of Nebraska. Those who have been working in the state have provided valuable information, but gaps of knowledge do exist in the state. With a majority of the work that has been done being focused on netting-based data collection, the state could benefit from a wide scale acoustic analysis of all of the species present. This is especially important now given the impending impacts of wind turbines and White-Nose Syndrome (WNS) that have the potential to negatively affect the bats of Nebraska. The more we are able to understand how the bats of Nebraska live within the landscape the better prepared we will be able to protect their habitat, lower the impacts of WNS, and wind energy development. The North American Bat program (NABat) is a national protocol designed to streamline data collection and encourage collaboration across ecoregions in order to allow for broad understanding of bat ecology, populations, and habitat usage. This project used NABat to study the full range of bats found in the state of Nebraska, determining the habitat characteristics that influence bat presence and absence across Nebraska using a combination of stationary and mobile ultrasound acoustic detectors. A secondary focus of the project will be to determine the ability of mobile transects to detect shifts in bat population trends. The combined use of stationary points and mobile transects establish a framework for determining the distribution of bat species across the state.	Many bat species are declining, but methods to monitor their populations are poorly developed. This project implements the North American Bat Monitoring Network in Nebraska. Such monitoring may provide warning of population declines, and provides information to improve bat-habitat models. This project is a partnership with the USGS and the Nebraska Cooperative Fish and Wildlife Research Unit. This project will result in a monitoring program and citizen science program to monitor bats across the state of Nebraska.
Global Change, Vulnerability and Resilience: Management Options for an Uncertian Future	January 2019	Our objectives for this project are to develop models to detect and assess ecological regime shifts in space and time, to identify components of adaptive capacity, and to identify species and techniques that may serve as leading indicators of thresholds of changing ecological regimes. We are utilizing monitoring and surveying data that is currently available in North America (e.g., Breeding Bird Surveys) with novel statistical tools and theory to assess long-term trends in the resilience of landscapes, changes in ecological regimes in both space and time, and species vulnerable to decline and extinction. We are employing various analytical and statistical techniques to quantify how core attributes of resilience (within-scale and cross-scale distributions of species and their functional traits) change over time in ecosystems and landscapes. Techniques used include, but are not limited to, stochastic modelling, information theory, and discontinuity analysis. Additionally, we will evaluate the significance of individual species to adaptive capacity, and thus the resilience of ecosystems and landscapes. We are conducting these analyses with data from the central United States with focal areas on Department of Defense managed properties, in particular Eglin Air Force Base, Florida, and Fort Riley, Kansas.	Ecological regime changes can be surprising and difficult to manage, and may threaten management goals Undesired regime changes can lead to species extinctions, and on DOD properties, can affect military readiness. This project is a collaboration with the USDOD, including Fort Riley and Eglin Air Force Base. This project will provide techniques to monitor for regime changes, and approaches that may provide early warning of impending regime changes.
Generation Novelty in Complex Systems	December 2019	Novelty and innovation are essential attributes for the continued success of ecological, social and other complex systems, both natural and anthropogenic. Without them, dynamic, adaptive change in response to disturbance is not possible. Novelty and innovation are required to keep existing complex systems resilient and adaptable, and to create new structures and interactions following catastrophic ecological or social failures. The importance of novelty is recognized in the management and business world, but is less explicitly recognized and appreciated in the scientific world. Without innovation and novelty, systems may become stagnant. Having a constant source of innovation and novelty is clearly important for systems, both following transformations and during their normal dynamics. However, novelty may be a destructive force as well. Invasive species, for example, can alter basic process and structure in ecosystems and be a source for decline or collapse. Cellular mutations can have obviously destructive consequences upon individuals and lineages—cancer is a prime example. Thus, innovation and novelty can be a double-edged sword. In ecosystems, for example, novelty in the form of new species has been a cause of major extinctions, but is also the prime source for recovery. To explore the causes and consequences of the generation of novelty and innovation for humans, for social systems and for ecological systems, we will convene a small diverse group of researchers from diverse disciplines, with a variety of approaches and backgrounds, where we believe a deliberate focus on the concept of novelty could be fruitful. Our overall intent is to identify commonalities across disciplines. What attributes of a system are necessary if novelty is to arise? What might be the consequences, both positive and negative, of systems structured to permit novelty and innovation?	The conditions for the emergence of novelty in complex systems are poorly understood. Better understanding will help us better cope with a variety of phenomena, both good and bad (such as invasions and extinctions). This project brings together researchers from the Resilience Alliance with McDonnell Foundation funded researchers in the areas of complex systems, brain cancer and mind-behavior interactions. A book or special journal feature will result from the workshop that will be supported by this project.
Evaluating Wetland Condition Across Nebraska	August 2018	Starting in 2011, the Environmental Protection Agency (EPA) initiated a program of National Wetland Condition Assessments (NWCA), with repeat sampling every five years. In addition to the National Assessment, Nebraska has participated in conducting an intensification of the project to increase the number of wetlands sampled in Nebraska. In 2011, wetlands in eleven Biologically Unique Landscapes were sampled. For the current study, the focus has been tightened onto five Biologically Unique Landscapes: Sandhill Fens in Cherry County and Western Subirrigated Alkaline Meadows in the northwest corner of Nebraska, Cottonwood–Diamond Willow Woodlands along the Loup Rivers, Eastern Bulrush Deep Marsh Community along the Central Platte, and Freshwater Seeps in northeastern Nebraska. The primary goals of this project are: 1. Evaluate the vegetation of the vegetation, soil and water of Nebraska wetlands, within five Biologically Unique Landscapes. 2. Identify benchmarks for similar wetlands to be compared to in the future.	Wetlands provide important ecosystem services, yet are threatened and often degraded. This project provides baseline data to assess the "health" of Nebraska wetlands, and provides data to the USEPA for a national wetland assessment. This project is a collaboration with the Nebraska Game and Parks Commission and the US EPA. Results will help state and federal managers make science based management decisions regarding wetlands in Nebraska and the U.S.
Aquatic Invasive Species (AIS) Prevention Program	December 2022	The Nebraska Invasive Species Program has facilitated development and implementation of a Nebraska Aquatic Invasive Species Prevention Program. Goals are to:<br>1. decrease the risk of introductions of aquatic invasive species in Nebraska through a watercraft inspection and decontamination program;<br>2. increase public awareness of aquatic invasive species through an integrated outreach and education program; and<br>3. increase local and regional collaborations for prevention and management of aquatic invasive species through directed and coordinated communications.<br><br>Boater surveys, watercraft inspections and outreach activities have been conducted since 2011 to increase public awareness of aquatic invasive species and promote prevention actions among watercraft users. In addition, the Coordinator served on regional aquatic invasive species panels to coordinate prevention and management efforts across state lines, delivered webinars to various audiences, provided over 15,000 outreach materials to partners, and collected water samples to assistance the U.S. Geological Survey eDNA pilot study on zebra mussel detection. Advertisements were ran in Nebraska Game and Parks Commission’s guides and other printed publications, and on two billboards. Two (one stationary at Lewis and Clark Lake and one trailered) CD3 waterless watercraft cleaning station were purchased; we monitor use of both units through an online platform.	Aquatic invasive species pose serious ecological and economic threats. Mitigating - and preventing - those threats is important for natural resource management and for managing other aspects of aquatic systems - such as riverine power plants. This project, with the Nebraska Game and Park Commission and numerous other collaborators, informs the public regarding aquatic invasives and helps coordinate management activities in Nebraska.
Monitoring, Mapping and Risk Assessment and Management of Invasive Species in Nebraska - Part I	December 2019	Funding was provided through a federal-aid grant from the Nebraska Game and Parks Commission to:<br><br>1. Provide outreach to and facilitate communication among stakeholders regarding biological invasions, coordinate the Nebraska Invasive Species Council, and assist with any additional legislation regarding invasive species as needed;<br><br>2. Develop management tools including an invasive species adaptive management plan, a risk analysis for high-risk invasive species in Nebraska, a multi-agency prevention protocol for preventing the spread of invasive species (terrestrial and aquatic), and identification of invasive species introduction pathways.	Invasive species are a threat to both species and to beneficial ecosystem services. As the kind and type of invasive species means they fall under a large number of management entities, coordination across these entities is important. This project is a collaboration among all the entities with an interface with invasive species in the state of Nebraska, state and federal. Outputs include risk analyses, management recommendations, and information sharing across partners.
Assessment of angler use and catch during 2018 at Sutherland Reservoir, Nebraska	January 2019	Creel survey.	Sutherland Reservoir (1,220 hectares) is the first canal reservoir downstream from Lake McConaughy and is utilized for the cooling of Nebraska Public Power District’s (NPPD) Gerald Gentleman Station. Permitting requires ongoing monitoring of activities, including recreational fishing. The purpose of this study is to estimate angler use and catch of Sutherland Reservoir, Nebraska, during 2018. This project is a collaboration of researchers across multiple agencies and includes the University of Nebraska—Lincoln and the Nebraska Public Power District. Information gained on angler behavior will be important for increased effectiveness of fishery management, as well as increased effectiveness of plant operations.
Comprehensive evaluation of the Nebraska outdoor enthusiast	July 2022	Fishing and hunting license sales and taxes on fishing and hunting equipment are vital sources of funding for wildlife management agencies, and in many cases, management objectives are met under the stewardship of sportspersons. The dependence on hunters and anglers by management agencies makes the North American Model of Conservation unique, but vulnerable to declining participation in outdoor recreation.<br><br>The U.S. Fish and Wildlife Service supports the National Survey of Fishing, Hunting, and Wildlife-Associated Recreation Survey in a nationwide effort to understand the sporting public. Conducted every five years, the National Survey identifies generalizations concerning patterns of outdoor enthusiast participation in the USA. Although useful for setting broad policy, the spatial and temporal scales of this National Survey limit the capacity for state fish and wildlife agencies to affect local participation within their states. To overcome these limitations, many state agencies conduct surveys of individual license holders. However, state surveys are often highly directed, limiting their applicability across user groups and state boundaries.<br><br> Given the challenges of both national and state surveys, there is a need to bridge the information gap and understand sportspersons at spatial and temporal scales that may more directly assist in creating hunting and angling opportunities. We are analyzing a comprehensive database on license holders in Nebraska with the goal of helping inform and direct wildlife and fisheries management, as well as recruitment and retention efforts within the state. To date, we have documented that movement of sportspersons across activity groups (hunting only, fishing only, a combination of hunting and fishing, and inactive), inferred from license purchases, is limited and varies little based on initial group participation. <br><br>In addition, we developed a customizable, open-source, web-based application—huntfishapp—that allows users to easily interact with a license database. The huntfishapp serves as an informational resource, provides a framework for sharing information on license sales across an agency, and allows agencies and non-governmental organizations to become more knowledgeable of their customer base.	The decline in hunters and anglers is of increasing concern to natural resource management agencies that depend on these individuals for annual funding. The dependence on hunters and anglers by natural resource management agencies makes the North American Model of Conservation unique, but vulnerable to declining participation in outdoor recreation. Comprehensive understanding of the hunting and fishing public is needed to inform and direct wildlife and fisheries management, as well as recruitment and retention efforts by natural resource management agencies. This project is a collaboration of researchers across multiple agencies and includes the University of Nebraska—Lincoln and the Nebraska Game and Parks Commission. Participation levels will be quantified among groups of hunters and anglers, and models will be developed to describe recruitment and development of these groups of people. Findings will help identify key socio-demographic parameters that predict movement among and retention in each of the user groups (e.g., from hunter education program to small-game hunter to angler to big-game hunter).

Kellermann (editors), Phenological synchrony and bird migration: changing climate and seasonal resources in North America. Studies in Avian Biology (no. 47), CRC Press, Boca Raton, FL. \| Abstract \| Download	January 2015	Changes in temperature and seasonality resulting from climate change are heterogeneous, potentially altering important sources of natural selection acting on species phenology. Although some species have apparently adapted to climate change, the adaptability of most species remains unknown. Because their life history is dictated by seasonal factors, migratory species may be particularly vulnerable to heterogeneous changes in climate and phenology. Here, we examine the phenology of migratory shorebirds, their habitat, and their primary food resources, and make forecast how climate change may affect migrants through predicted changes in phenology. Daily abundance of shorebirds at stopover sites is correlated with local phenology and peaked immediately prior to peaks in invertebrate food resources in the Prairie Pothole region. A close relationship between migrant and invertebrate phenology indicates that shorebirds may be vulnerable to changes in seasonality driven by climate change. Although it is possible that shifts in migrant and invertebrate phenology will be congruent in magnitude and direction, because migration phenology is dependent on a suite of ecological factors, any response is likely to occur at a larger temporal scale and may lag behind the response of invertebrate food resources. The resulting lack of sufficient access to food at stopover habitats may cause migrants to extend migration and have cascading effects throughout their life-cycle. If the heterogeneous nature of climate change results in uneven changes in phenology between migrants and their prey, it may threaten the long-term viability of migratory populations.

Stevens, J.N., C.E. Barshinger, J.J. Spurgeon, M.A. Eggleton, and S.E. Lochmann. 2024. Comparison of two otolith processing methods for Silver Carp age estimation. Journal of the Southeastern Association of Fish and Wildlife Agencies. \| Abstract	April 2024	Accurate age estimates are critical in the development, implementation, and assessment of silver carp (<i>Hypophthalmichthys molitrix</i>) management plans. Lapilli otoliths are the most commonly used hard structures for silver carp age estimation, though data regarding the precision of two established preparation methods (i.e., grind-and-burn, thin-section) are lacking. To compare the two methods, we assessed within-reader, between-reader, and between-method precision for 125 silver carp collected from six rivers throughout the Lower Mississippi River Basin (Arkansas, Cache, Mississippi, St. Francis, White, and Yazoo). Additionally, we compared the effort and material costs associated with each method. Overall, the grind-and-burn method (mean age ± SE = 5.97 ± 0.18 years) resulted in younger estimated ages than the thin-section method (mean age ± SE = 6.90 ± 0.18 years), particularly in older individuals. The thin-section method (average coefficient of variation = 7.964) displayed slightly greater between-reader precision than the grind-and-burn method (average coefficient of variation = 8.072), but raw data plots revealed lower precision at older ages relative to younger ages. This discrepancy between methods may be a result of misidentification of annuli near the otolith margin as both readers reported that sectioned otoliths offered clearer views than burned and ground otoliths. Processing times and material costs were similar for the two methods and are likely not limiting when choosing an aging protocol. Our results indicate that managers may be able to use the grind-and-burn method to estimate silver carp age in younger populations where older fish are uncommon. However, the thin-section method for silver carp age estimation may lead to less biased age estimates for established populations with greater abundances of older individuals.

Are agrofuels a conservation threat or opportunity for grassland birds in the United States? Condor 114:679-688 \| Abstract \| Download	October 2012	In the United States, government-mandated growth in the production of crops dedicated to biofuel (agrofuels) is predicted to increase the demands on existing agricultural lands, potentially threatening the persistence of populations of grassland birds they support. We review recently published literature and datasets to (1) examine the ability of alternative agrofuel crops and their management regimes to provide habitat for grassland birds, (2) determine how crop placement in agricultural landscapes and agrofuel-related land-use change will affect grassland birds, and (3) identify critical research and policy-development needs associated with agrofuel production. We find that native perennial plants proposed as feedstock for agrofuel (switchgrass, Panicum virgatum, and mixed grass–forb prairie) have considerable potential to provide new habitat to a wide range of grassland birds, including rare and threatened species. However, industrialization of agrofuel production that maximizes biomass, homogenizes vegetation structure, and results in the cultivation of small fields within largely forested landscapes is likely to reduce species richness and/or abundance of grassland-dependent birds. Realizing the potential benefits of agrofuel production for grassland birds’ conservation will require the development of new policies that encourage agricultural practices specifically targeting the needs of grassland specialists. The broad array of grower-incentive programs in existence may deliver new agrofuel policies effectively but will require coordination at a spatial scale broader than currently practiced, preferably within an adaptive-management framework.

Ornithology 121:815-818. \| Abstract \| Download	December 2009	Studies of song and its function in suboscine passerines are rare. We examined spatial and temporal variation in song structure in a wild population of Olive-sided Flycatchers (Contopus cooperi) and tested among hypotheses explaining this variation. Repeatable variation in song type was observed both within and among individuals. More than 10% of territorial males expressed atypical song types, i.e., permutations of sequential missing and repeated elements of the typical adult song. Atypical songs were predominantly expressed by unpaired males independent of habitat type. A small fraction of males sang atypical song through the middle of the breeding season, but all males sang only stereotypical adult song by the end of the season. These results suggest the expression of atypical songs reflect protracted vocal development rather than evolution of new song types, geographic variation in song structure, or an extensive song repertoire in Olive-sided Flycatchers.

Ecology and evolution, 9(4), 1869-1879. https://doi.org/10.1002/ece3.4879 \| Abstract \| Download	December 2019	Disturbance legacies structure communities and ecological memory, but due to increasing changes in disturbance regimes, it is becoming more difficult to characterize disturbance legacies or determine how long they persist. We sought to quantify the characteristics and persistence of material legacies (e.g., biotic residuals of disturbance) that arise from variation in fire severity in an eastern ponderosa pine forest in North America. We compared forest stand structure and understory woody plant and bird community composition and species richness across unburned, low‐, moderate‐, and high‐severity burn patches in a 27‐year‐old mixed‐severity wildfire that had received minimal post‐fire management. We identified distinct tree densities (high: 14.3 ± 7.4 trees per ha, moderate: 22.3 ± 12.6, low: 135.3 ± 57.1, unburned: 907.9 ± 246.2) and coarse woody debris cover (high: 8.5 ± 1.6% cover per 30 m transect, moderate: 4.3 ± 0.7, low: 2.3 ± 0.6, unburned: 1.0 ± 0.4) among burn severities. Understory woody plant communities differed between high‐severity patches, moderate‐ and low‐severity patches, and unburned patches (all <i>p</i> < 0.05). Bird communities differed between high‐ and moderate‐severity patches, low‐severity patches, and unburned patches (all <i>p</i> < 0.05). Bird species richness varied across burn severities: low‐severity patches had the highest (5.29 ± 1.44) and high‐severity patches had the lowest (2.87 ± 0.72). Understory woody plant richness was highest in unburned (5.93 ± 1.10) and high‐severity (5.07 ± 1.17) patches, and it was lower in moderate‐ (3.43 ± 1.17) and low‐severity (3.43 ± 1.06) patches. We show material fire legacies persisted decades after the mixed‐severity wildfire in eastern ponderosa forest, fostering distinct structures, communities, and species in burned versus unburned patches and across fire severities. At a patch scale, eastern and western ponderosa system responses to mixed‐severity fires were consistent.

Oikos 123:971-983. \| Abstract	November 2014	1. Body size is linked to a range of ecological and life history traits, and thus provides a useful proxy for understanding individual, population and community level attributes and processes. Habitat structure across multiple scales has been proposed as a key driver of body size distributions for associated communities. Thus, understanding the relationship between habitat and body size is fundamental to developing predictions regarding the influence of future disturbances and habitat degradation on the distribution of body size within communities. 2.To date much of the work assessing the relationship between cross-scale habitat structure and body size distributions has focused on terrestrial taxa with determinate growth, and has primarily analysed discontinuities in species mean size distributions (SMSDs). The suitability of this approach for marine taxa, exhibiting indeterminate growth, has yet to be determined. 3.Here we provide a cross-ecosystem comparison of bird and fish body mass distributions, evaluating three size distribution indices: SMSDs, local size density relationships (LSDRs), and individual size density relationships (ISDs) and two types of analysis (discontinuity vs. modality), to highlight their respective suitability for exploring habitat-body size relationships in different taxa and ecosystems. 4.All three indices of body size distribution are useful for examining the relationship between cross-scale habitat structure and body size for species with determinate growth, such as birds. In contrast, for species with indeterminate growth, such as fish, the relationship between habitat structure and body size may be masked when using summary metrics, and thus ISDs are more useful. Furthermore, evaluating modality and abundance patterns in size distributions provides a more powerful way of assessing habitat impacts, than assessing discontinuity patterns. 5.It is critical to consider the life-history and ecology of taxa when selecting analytical approaches for evaluating body size distributions. Inappropriate use of summary metrics for species with indeterminate growth may hide the influence of drivers and provide misleading research outcomes. Critically, although ISDs are traditionally used to study aquatic systems, they present a common currency for comparing body size distributions across ecosystems.

By selecting locations or ‘habitats’ with many benefits (e.g., food, shelter, mates) and few costs (e.g., predation), animals improve their ability to survive and reproduce. Biologists track animal movement using radio telemetry technology to study habitat selection so they can better provide species with habitats that promote population growth. We present a curricula in which students locate “animals” (transmitters) using radio telemetry equipment and apply math skills (use of fractions and percentages) to assess their animal’s habitat selection by comparing the availability of habitat types with the proportion of ‘animals’ found in each habitat type.

Plos One 9:e99339. doi:10.1371/journal.pone.0099339 \| Abstract	May 2014	Landscapes in agricultural systems continue to undergo significant change, and the loss of biodiversity is an ever-increasing threat. Although habitat restoration is beneficial, management actions do not always result in the desired outcome. Managers must understand why management actions fail; yet, past studies have focused on assessing habitat attributes at a single spatial scale, and often fail to consider the importance of ecological mechanisms that act across spatial scales. We located survey sites across southern Nebraska, USA and conducted point counts to estimate Ring-necked Pheasant abundance, an economically important species to the region, while simultaneously quantifying landscape effects using a geographic information system. To identify suitable areas for allocating limited management resources, we assessed land cover relationships to our counts using a Bayesian binomial-Poisson hierarchical model to construct predictive Species Distribution Models of relative abundance. Our results indicated that landscape scale land cover variables severely constrained or, alternatively, facilitated the positive effects of local land management for Ring-necked Pheasants.

Most research concerning Common Snook in North America has been conducted in Florida and very little is known about the specific biology and habitat needs of Common Snook in Texas. The primary objective of this study was to describe the habitat use patterns of juvenile Common Snook and their role in the fish assemblage in the lower portion of the Rio Grande, Texas. Secondarily, we documented the relationship between age and juvenile reproductive development. Fish were collected during January-March 2006 from the lower 51.5 km of the Rio Grande using a bottom trawl and boat-mounted electrofisher. Measurements of water quality (temperature, dissolved oxygen, conductivity, etc.) and other habitat traits (bank slope, presence of vegetation or woody debris, flow, etc.) were recorded at each sampling site. We captured Common Snook (n = 225) exclusively in freshwater habitats above river kilometer 12.9. The distribution of juvenile Common Snook was not random, but influenced primarily by turbidity and dissolved oxygen. Sex differentiation and gonadal development based on histological examination of gonads established that age–1 and age–2 Common Snook were juvenile, prepubertal males. There was no difference between the age groups in their overall distribution in the river. However, age-2 Common Snook were associated with deeper areas with faster currents, higher conductivity, and steeper banks. Overall, Common Snook in the lower Rio Grande show substantial differences in habitat use than counterparts in other parts of the range of the species, but it is unclear whether this is due to differences in habitat availability, behavioral plasticity, or some combination thereof.

Climatic Change 97:305-311. \| Abstract \| Download	May 2009	Recent changes in global climate have dramatically altered worldwide temperatures and the corresponding timing of seasonal climate conditions. Recognizing the degree to which species respond to changing climates is therefore an area of increasing conservation concern as species that are unable to respond face increased risk of extinction. Here we examine spatial and temporal heterogeneity in the rate of climate change across western North America and discuss the potential for conditions to arise that may limit the ability of western migratory birds to adapt to changing climates. Based on 52 years of climate data, we show that changes in temperature and precipitation differ significantly between spring migration habitats in the desert southwest and breeding habitats throughout western North America. Such differences may ultimately increase costs to individual birds and thereby threaten the long-term population viability of many species.

Quantifying cross-scale spatial patterns and their local and regional correlates in headwater streams: implications for resilience. Ecology and Society 19(3): 15. http://dx.doi.org/10.5751/ES-06750-190315. \| Abstract	December 2014	The distribution of functional traits within and across spatiotemporal scales has been used to quantify and infer the relative resilience across ecosystems. In this study, we use explicit spatial modeling to evaluate the adequacy of within-and cross-scale patterns as surrogates of resilience in headwater streams, an ecosystem type with hierarchical and dendritic network structure. We assessed the cross-scale distribution of functional feeding groups of benthic invertebrates in Swedish headwater streams during two seasons. We evaluated functional metrics (Shannon diversity, species richness, and evenness) and the degree of redundancy within and across modeled spatial scales for individual feeding groups. We also estimated the correlates of environmental vs spatial factors of both functional composition and the taxonomic composition of functional groups for each spatial scale identified. Measures of functional diversity and within-scale redundancy of functions were similar during both seasons, but both within- and cross-scale redundancy were low, suggesting an apparent low relative resilience of the stream network. This apparent low resilience was partly due to a few dominant taxa explaining the spatial models. Two findings derive from our study. First, both environmental and spatial factors can correlate with the scale-specific functional and taxonomic composition, suggesting that resilience in stream networks emerges as a function of both local conditions and regional factors (habitat connectivity and invertebrate dispersal). Second, quantifying within- and cross-scale patterns may underestimate resilience, limiting their use as surrogates of overall resilience in streams. Rare taxa with stochastic spatial distributions might provide additional information and will need to be considered explicitly for complementing resilience assessments.

Frontiers in Environmental Science 11. https://doi.org/10.3389/fenvs.2023.1151315 \| Abstract \| Download \| Publisher Website	March 2023	Rehabilitation of large Anthropocene rivers requires engagement of diverse stakeholders across a broad range of sociopolitical boundaries. Competing objectives often constrain options for ecological restoration of large rivers whereas fewer competing objectives may exist in a subset of tributaries. Further, tributaries contribute toward building a “portfolio” of river ecosystem assets through physical and biological processes that may present opportunities to enhance the resilience of large river fishes. Our goal is to review roles of tributaries in enhancing mainstem large river fish populations. We present case histories from two greatly altered and distinct large-river tributary systems that highlight how tributaries contribute four portfolio assets to support large-river fish populations: 1) habitat diversity, 2) connectivity, 3) ecological asynchrony, and 4) density-dependent processes. Finally, we identify future research directions to advance our understanding of tributary roles and inform conservation actions. In the Missouri River USA, we focus on conservation efforts for the state endangered lake sturgeon, which inhabits large rivers and tributaries in the Midwest and Eastern USA. In the Colorado River, Grand Canyon USA, we focus on conservation efforts for recovery of the federally threatened humpback chub. In the Missouri River, habitat diversity focused on physical habitats such as substrate for reproduction, and deep-water habitats for refuge, whereas augmenting habitat diversity for Colorado River fishes focused on managing populations in tributaries with minimally impaired thermal and flow regimes. Connectivity enhancements in the Missouri River focused on increasing habitat accessibility that may require removal of physical structures like low-head dams; whereas in the Colorado River, the lack of connectivity may benefit native fishes as the disconnection provides refuge from nonnative fish predation. Hydrologic variability among tributaries was present in both systems, likely underscoring ecological asynchrony. These case studies also described density dependent processes that could influence success of restoration actions. Although actions to restore populations varied by river system, these examples show that these four portfolio assets can help guide restoration activities across a diverse range of mainstem rivers and their tributaries. Using these assets as a guide, we suggest these can be transferable to other large river-tributary systems.

Similar resilience attributes in lakes with different management practices.PLoS ONE 9(3):e91881. doi: 0.1371/journal.pone.0091881. \| Abstract	April 2014	Liming has been used extensively in Scandinavia and elsewhere since the 1970s to counteract the negative effects of acidification. Communities in limed lakes usually return to acidified conditions once liming is discontinued, suggesting that liming is unlikely to shift acidified lakes to a state equivalent to pre-acidification conditions that requires no further management intervention. While this suggests a low resilience of limed lakes, attributes that confer resilience have not been assessed, limiting our understanding of the efficiency of costly management programs. In this study, we assessed community metrics (diversity, richness, evenness, biovolume), multivariate community structure and the relative resilience of phytoplankton in limed, acidified and circum-neutral lakes from 1997 to 2009, using multivariate time series modeling. We identified dominant temporal frequencies in the data, allowing us to track community change at distinct temporal scales. We assessed two attributes of relative resilience (cross-scale and within-scale structure) of the phytoplankton communities, based on the fluctuation frequency patterns identified. We also assessed species with stochastic temporal dynamics. Liming increased phytoplankton diversity and richness; however, multivariate community structure differed in limed relative to acidified and circum-neutral lakes. Cross-scale and within-scale attributes of resilience were similar across all lakes studied but the contribution of those species exhibiting stochastic dynamics was higher in the acidified and limed compared to circum-neutral lakes. From a resilience perspective, our results suggest that limed lakes comprise a particular condition of an acidified lake state. This explains why liming does not move acidified lakes out of a “degraded” basin of attraction. In addition, our study demonstrates the potential of time series modeling to assess the efficiency of restoration and management outcomes through quantification of the attributes contributing to resilience in ecosystems.

Oral presentation at the 2016 Natural Legacy Conference, Broken Bow, NE.	September 2016	Most recent studies have extrapolated effects to a broader scale (county, national, or global) by assuming bats homogenously utilize all agricultural fields regardless of proximity to beneficial landscape features such as water or potential roost sites. Our research suggests that this is a false assumption, with bat activity having high levels of spatial, temporal, and species-specific variation.

Dillon T. Fogarty, Dirac Twidwell, & Craig R. Allen. Ecosystem Service Trade offs Associated with Eastern Redcedar in Nebraska. Nebraska Natural Legacy Project 2017 Location: Lied Lodge & Conference Center, Nebraska City, NE 68410. Dates: October 10-11, 2017	October 2017	To maintain current suites of ESs, communities often place a high priority on preventing the spread of invasive species; however, most invasive species benefit at least one ES, but have an overall negative impact on ES provisioning. ES gains at the shelterbelt scale have likely led to management practices that promote cedar persistence and therefore the loss of ESs in rangelands.

Southern Division American Fisheries Society Annual Meeting, Norfolk, Virginia.	February 2023	Silver Carp <i>Hypophthalmichthys molitrix </i>is an invasive species found throughout the Mississippi River basin. Main-channel residency periods varied based on river and season. Overall, movement patterns suggest movement of Silver Carp in the Arkansas River is limited by the numerous locks and dams of the McClellan Kerr Arkansas River Navigation System.

February 2014	While the concept has been widely embraced in the natural resource community, there have been relatively few demonstrations of adaptive management implementation that successfully takes action and reduces key uncertainties. We describe a case study that integrates the adaptive management framework into an invasive tree removal project to not only demonstrate the difficulties of implementation efforts, but also expound upon the perceived benefits of the approach.
