Assessing consequences of anthropogenic hybridization: Great Lakes mallard movement and resource selection

The release of domesticated animals is resulting in anthropogenic hybridization with their wild congeners and there is concern that these interactions are a risk to conservation. In North America, large-scale releases of domesticated mallards have continued for over a century, ye...

Evaluating juvenile post-stocking survival and adult paddlefish spatial distribution for recreational fishery potential in a large reservoir

Angler interest in targeting Paddlefish Polyodon spathula is growing throughout the Missouri and Mississippi River basins. In response, state agencies are increasing management efforts (e.g., stocking) and evaluating whether restored or maintained populations are suitable candida...

Reservoir cascades as directional invasion corridors

Abstract Reservoir cascades in large river systems impose directional pathways that can structure biological invasions, yet how these pathways interact with propagule supply and lock-mediated passage opportunity to influence arrival timing remains poorly understood. We used inter...

The scaling of motion: dynamic body acceleration declines with body mass in black-tailed prairie dogs

Dynamic body acceleration (DBA) derived from animal-borne accelerometers is widely used to infer behaviour and movement-related energetic expenditure, yet its interpretation in comparative contexts may be complicated by body size. Biomechanical scaling predicts that smaller anima...

Native Wolbachia infection dynamics across Aedes albopictus (Diptera: Culicidae) populations in Hawaiʻi

Aedes albopictus , an important vector of arboviruses, such as dengue, chikungunya, and Zika, is a widespread invasive mosquito species in the Pacific Islands Countries and Territories, including Hawaiʻi. Wolbachia , an endosymbiotic bacterium, widely used for mosquito control th...

Four coding-complete genomes of bovine viral diarrhea virus-2a ( Orthopestivirus tauri genotype a) isolated from farmed white-tailed deer ( Odocoileus virginianus ) in Florida, USA, in 2018

To date, no bovine viral diarrhea virus-2 (BVDV-2) coding-complete genomes are available from white-tailed deer (WTD) in Florida. We determined the coding-complete genome sequences of four BVDV-2 isolates from farmed WTD that were found dead in 2018. These belonged to BVDV-2 sub-...

Incorporating Wetland Drowning Thresholds to Assess the Spatiotemporal Variability in Potential Wetland Migration and Submergence From Sea-Level Rise

Abstract In the coming decades sea-level rise rates could exceed the upper bounds of coastal wetland vertical movement leading to wetland submergence. Consequently, understanding the spatiotemporal variability of wetland migration and submergence at regional and national scales c...

The Rising Threat of Lead: Trends in Fatalities of California Condors

ABSTRACT Endangered species face threats that change over time, and understanding variation in the importance of threats is valuable for guiding species recovery. The reintroduced population of critically endangered California condors has faced a number of threats over the three...

Taking smart conservation risks: Moving species in a changing world

Abstract Conservation practitioners are often faced with difficult decisions on whether or not to implement intensive interventions that carry risk and uncertainty—such as translocating species outside their indigenous range for the purpose of conservation (i.e., conservation int...

Efficacy of mitigation translocation from Anchorage, Alaska airfields for short-eared owls and red-tailed hawks

Abstract Background Mitigation translocation is widely used at airfields to reduce wildlife-aircraft strike risk, yet few studies have evaluated its effectiveness for raptors, and none have been conducted in Alaska. We assessed post-release return rates for red-tailed hawks ( But...
