Re-emergence of Guadalupe fur seals in Oregon and Washington with Dr. Erin D’Agnese
11 February 2021 at 4 PM Pacific Time (12 AM UTC)

About this talk:
This talk discusses the health risks facing Guadalupe fur seals (Arctocephalus phillippii townsendi; GFS) as they re-emerge in their historic, pre-sealing, migration range. The continued presence of the species in the Pacific Northwest of the United States, was largely represented by juvenile animals and was seasonally driven. Their stranding numbers were related to the seasonal upwelling present in the area during summer months. Detailed necropsies, histopathology (n=93) and epidemiological analysis found three main causes of death (COD): emaciation (44%), trauma (29%), and infectious disease (19%) and the factors associated with overall strandings and emaciation. Trauma included many cases found associated with fisheries interactions and clustered near the mouth of the Columbia River where high levels of commercial fishing occurs. Re-emergence of GFSs is likely due to conservation efforts, which have been critical for species recovery in the region, continued monitoring is needed as this vulnerable species continues to rebound and faces pressures of increased fisheries in the region.
