Potential Tool Use by Wolves (<i>Canis lupus</i>): Crab Trap Pulling in Haíɫzaqv Nation Territory. [PDF]
Ecol EvolRecently, recurring damage to crab traps used by Haíɫzaqv Nation Guardians to control a European Green Crab invasion was investigated with remote cameras. A wolf was recorded emerging from the water carrying a crab trap buoy, then sequentially pulling the attached line up the beach until the initially submerged trap emerged from the water, with the ...

Population Trend and Elasticities of Vital Rates for Steller Sea Lions (Eumetopias jubatus) in the Eastern Gulf of Alaska: A New Life-History Table Analysis. [PDF]
PLoS ONE, 2015 Steller sea lion (Eumetopias jubatus) numbers are beginning to recover across most of the western distinct population segment following catastrophic declines that began in the 1970s and ended around the turn of the century.

Congenital Ocular Findings in an Antillean Manatee (Trichechus manatus manatus). [PDF]
Vet Med SciThis study reports the first documented case of bilateral congenital cataract associated with retinal dysplasia in an Antillean manatee (Trichechus manatus manatus) calf. Ophthalmologic examination and ocular ultrasonography confirmed lens opacity at the posterior pole, which correlated with behavioural deficits consistent with visual impairment.

Survival of adult Steller sea lions in Alaska: senescence, annual variation and covariation with male reproductive success [PDF]
Royal Society Open Science, 2018 Population dynamics of long-lived vertebrates depend critically on adult survival, yet factors affecting survival and covariation between survival and other vital rates in adults remain poorly examined for many taxonomic groups of long-lived mammals (e.g.
