Abstract:
... The low diversity in marine mammal major histocompatibility complex (MHC) appears to support the hypothesis of reduced pathogen selective pressure in aquatic systems compared to terrestrial environments. However, the lack of characterization of the aquatic and evolutionarily distant Sirenia precludes drawing more generalized conclusions. Therefore, we aimed to characterize the MHC DQB diversity of ...

Abstract:
... The historic extirpation and subsequent recovery of sea otters (Enhydra lutris) have profoundly changed coastal social-ecological systems across the northeastern Pacific. Today, the conservation status of sea otters is informed by estimates of population carrying capacity or growth rates independent of human impacts. However, archaeological and ethnographic evidence suggests that for millennia, co ...

Abstract:
... Beach users play a fundamental role in responses to marine mammal strandings (RMMS), as they are usually the first to detect and report strandings. Informed beach users facilitate effective responses, increasing the odds of rescuing live animals and obtaining data on the stranding events. This information allows for the causes of stranding events to be related with climatic, anthropogenic, or ocea ...

Abstract:
... Fundamental movements of migratory species can be substantially influenced by marine habitat disruptions caused by coastal infrastructure. The Hood Canal Bridge (HCB) spans the northern outlet of Hood Canal in the Salish Sea, extends 4.6 m (15 ft) underwater, and forms a partial barrier for steelhead migrating from Hood Canal to the Pacific Ocean. Spatial mark–recapture survival models using acous ...

... Surrogates are used in conservation planning to select sites to represent species when information about species’ geographical distributions is insufficient. Many surrogates for biodiversity have used biotic (e.g., vegetation assemblages) or biogeographic distributions of a group of species (e.g., birds) that are easier to inventory than more cryptic species of interest. Because knowledge of speci ...

... Incidental bycatch in fisheries is a pressing conservation issue for marine mammal populations across the globe. However, the ability to detect and therefore mitigate this issue is challenging for several reasons. Fishermen are unlikely to voluntarily report bycatch due to fear of penalization or apathy towards it. While fisheries observer programs are sometimes in place to record bycatch, many fi ...
