PCB exposure in sea otters and harlequin ducks in relation to history of contamination by the Exxon Valdez oil spill PCB exposure in sea otters and harlequin ducks in relation to history of contamination by the Exxon Valdez oil spill
Exposure to contaminants other than petroleum hydrocarbons could confound interpretation of Exxon Valdez oil spill effects on biota at Prince William Sound, Alaska. Hence, we investigated polychlorinated biphenyls (PCBs) in blood of sea otters and harlequin ducks sampled during 1998. PCB concentrations characterized by lower chlorinated congeners were highest in sea otters from the...

Using ecological function to develop recovery criteria for depleted species: Sea otters and kelp forests in the Aleutian archipelago Using ecological function to develop recovery criteria for depleted species: Sea otters and kelp forests in the Aleutian archipelago
Recovery criteria for depleted species or populations normally are based on demographic measures, the goal being to maintain enough individuals over a sufficiently large area to assure a socially tolerable risk of future extinction. Such demographically based recovery criteria may be insufficient to restore the functional roles of strongly interacting species. We explored the idea of...

The nearshore benthic community of Kasatochi Island, one year after the 2008 volcanic eruption The nearshore benthic community of Kasatochi Island, one year after the 2008 volcanic eruption
A description is presented of the nearshore benthic community of Kasatochi Island 10–12 months after a catastrophic volcanic eruption in 2008. The eruption extended the coastline of the island approximately 400 m offshore, mainly along the south, southeast, and southwest shores, to roughly the 20 m isobath. Existing canopy kelp of Eualaria (Alaria) fistulosa, as well as limited...

Status and Trends of Sea Otter Populations in Southeast Alaska, 1969-2003 Status and Trends of Sea Otter Populations in Southeast Alaska, 1969-2003
Aerial surveys of all known sea otter (Enhydra lutris) habitat in Southeast Alaska (SE AK) in 2002-2003 indicated a population size of 8,949 otters [Standard Error (SE) = 899] at an average density of 0.92 otters per square kilometer. These findings on sea otter distribution and abundance were compared to results from several previous surveys. Sea otters have expanded their range beyond...

Otters, Marine Otters, Marine
The otters (Mustelidae; Lutrinae) provide an exceptional perspective into the evolution of marine living by mammals. Most extant marine mammals (e.g. the cetaceans, pinnipeds, and sirenians) have been so highly modified by long periods of selection for life in the sea that they bear little resemblance to their terrestrial ancestors. Marine otters, in contrast, are more recent expatriates...

Phenotypic plasticity in age at first reproduction of female northern sea otters (Enhydra lutris kenyoni) Phenotypic plasticity in age at first reproduction of female northern sea otters (Enhydra lutris kenyoni)
Life-history theory predicts that within a species, reproduction and survival rates will differ among populations that differ in resource availability or predation rates through phenotypic plasticity. When populations are near carrying capacity (K) or when they are declining due to reduced prey resources, the average age at 1st reproduction (average AFR) is predicted to be older than in
