The southern Beaufort Sea polar bear sub-population (Ursus maritimus) has been adversely affected by climate change and loss of sea ice habitat. Even though the is likely decreasing, it remains difficult to link individual health physiological effects. We developed an index allostatic load, which represents potential dysregulation. load included blood- hair-based analytes measured in physically captured bears spring. examined relation body condition, age, terrestrial habitat use and, over...
Cryptococcus gattii is a fungal pathogen that primarily affects the respiratory and nervous systems of humans other animals. C. emerged in temperate North America 1999 as multispecies outbreak cryptococcosis British Columbia (Canada) Washington State Oregon (USA), affecting humans, domestic animals, wildlife. Here we describe epizootic odontocetes. Cases were identified 42 odontocetes between 1997 2016. Species affected included harbor porpoises Phocoena phocoena (n = 26), Dall's...
In savannas across the planet, encroaching woody plants are altering ecosystem functions and reshaping communities. Seed predation by rodents may serve to slow encroachment of in grasslands savannas. Our goals for this study were determine if an African savanna selectively removed seeds plant foraging activity was influenced local vegetation structure or landscape context. From trials with two species (encroacher = Dichrostachys cinerea , non-encroaching overstory tree Senegalia nigrescens )...
Abstract Endangered Southern Resident killer whales ( Orcinus orca ) are fish‐eaters that preferentially prey on adult Chinook salmon Oncorhynchus tshawytscha ). Despite being specialists, individuals from all three whale pods (J, K, L) have been observed harassing and killing porpoises (family Phocoenidae) without consuming them. Retrospectively, we identified analyzed 78 episodes of between 1962 2020, which 28 resulted in the porpoise's death (“phocoenacide”). Fifty‐six involved harbor...
In the United States, Canada, and Europe harbor seal (Phoca vitulina) pups are commonly rehabilitated after stranding then released. Size at release is likely important to post-release survival; however, data have not been compiled track body condition of seals across U.S. To better understand spatiotemporal variations in morphometrics during rehabilitation release, this study retrospectively analyzed conditions, weights, lengths, growth rates Body index (BCI) was calculated, weight BCI were...
Abstract Blood crossmatching is necessary to determine transfusion compatibility between individuals, especially for species which blood groups have not yet been defined, such as the killer whale ( Orcinus orca ). This study evaluated methodology in whales from a managed care population using individuals of known lineages. Twenty were major or minor crossmatch incompatibilities, determined by evidence macro‐agglutination. Crossmatching incompatibilities rarely observed, both when considering...
