Quantifying seining detection probability for fishes of Great Plains sand‐bed rivers Quantifying seining detection probability for fishes of Great Plains sand‐bed rivers
Species detection error (i.e., imperfect and variable detection probability) is an essential consideration when investigators map distributions and interpret habitat associations. When fish detection error that is due to highly variable instream environments needs to be addressed, sand‐bed streams of the Great Plains represent a unique challenge. We quantified seining detection...

Response of beach-nesting American Oystercatchers to off-road vehicles: An experimental approach reveals physiological nuances and decreased nest attendance Response of beach-nesting American Oystercatchers to off-road vehicles: An experimental approach reveals physiological nuances and decreased nest attendance
Shorebird populations face increasing challenges as rising sea levels and growing human populations constrain their breeding habitats. On recreational beaches, the nesting season often coincides with a season of high visitor use, increasing the potential for conflict, which may negatively influence beach-nesting shorebird species. We designed a field experiment to study the responses of...

Adaptive influence of extrinsic and intrinsic factors on variation of incubation periods among tropical and temperate passerines Adaptive influence of extrinsic and intrinsic factors on variation of incubation periods among tropical and temperate passerines
Understanding intrinsic (physiological) and extrinsic (e.g., temperature) causes of variation in embryonic development time (incubation period) is important because they can have different impacts on individual quality. Robert Ricklefs and colleagues have argued that longer incubation periods result primarily from intrinsic physiological programs that increase individual quality and...

Distinguishing values from science in decision making: Setting harvest quotas for mountain lions in Montana Distinguishing values from science in decision making: Setting harvest quotas for mountain lions in Montana
The relative roles of science and human values can be difficult to distinguish when informal processes are used to make complex and contentious decisions in wildlife management. Structured Decision Making (SDM) offers a formal process for making such decisions, where scientific results and concepts can be disentangled from the values of differing stakeholders. We used SDM to formally...

AMModels: An R package for storing models, data, and metadata to facilitate adaptive management AMModels: An R package for storing models, data, and metadata to facilitate adaptive management
Agencies are increasingly called upon to implement their natural resource management programs within an adaptive management (AM) framework. This article provides the background and motivation for the R package, AMModels. AMModels was developed under R version 3.2.2. The overall goal of AMModels is simple: To codify knowledge in the form of models and to store it, along with models...

The potential of unmanned aerial systems for sea turtle research and conservation: a review and future directions The potential of unmanned aerial systems for sea turtle research and conservation: a review and future directions
The use of satellite systems and manned aircraft surveys for remote data collection has been shown to be transformative for sea turtle conservation and research by enabling the collection of data on turtles and their habitats over larger areas than can be achieved by surveys on foot or by boat. Unmanned aerial vehicles (UAVs) or drones are increasingly being adopted to gather data, at...

Seasonal trophic variation of yellow perch exceeds spatial variation in a large lake basin Seasonal trophic variation of yellow perch exceeds spatial variation in a large lake basin
Trophic structuring of complex food webs may vary at multiple spatial and temporal scales, both in terms of direct trophic connections and underlying energy pathways that support production. In large freshwater systems, the prey and primary producers that support individual higher-order consumers may vary across seasons and habitats due to differences in food availability, predator...

Resilience concepts in psychiatry demonstrated with bipolar disorder Resilience concepts in psychiatry demonstrated with bipolar disorder
Background The term resilience describes stress–response patterns of subjects across scientific disciplines. In ecology, advances have been made to clearly distinguish resilience definitions based on underlying mechanistic assumptions. Engineering resilience (rebound) is used for describing the ability of subjects to recover from adverse conditions (disturbances), and is the rate of...

Cooperative Fish and Wildlife Research Units Program—2017 year in review Cooperative Fish and Wildlife Research Units Program—2017 year in review
The Cooperative Fish and Wildlife Research Units Program was involved in a number of notable events during 2017, many concerning our personnel. Dr. Barry Grand left his position as Leader of the Alabama Cooperative Fish and Wildlife Research Unit to become the Cooperative Units Program Supervisor for the South, replacing Dr. Kevin Whalen who took over as Supervisor for the West. We...
