Marine predator surveys in Glacier Bay National Park and Preserve
Since 1999, vessel based surveys to estimate species composition, distribution and relative abundance of marine birds and mammals have been conducted along coastal and pelagic (offshore) transects in Glacier Bay, Alaska. Surveys have been conducted during winter (November-March) and summer (June). This annual report presents the results of those surveys conducted in March and June of 2001. FollowiAuthorsJames L.

Sea otter population status and the process of recovery from the 1989 Exxon Valdez oil spill
Sea otter (Enhydra lutris) populations were severely affected by the 1989 Exxon Valdez oil spill in western Prince William Sound, AK, and had not fully recovered by 2000. Here we present results of population surveys and incorporate findings from related studies to identify current population status and factors affecting recovery.

Monson, Charles E. O'Clair, Glenn R. VanBlaricomMicrosatellite DNA and mitochondrial DNA variation in remnant and translocated sea otter (Enhydra lutris) populations
All existing sea otter (Enhydra lutris) populations have suffered at least 1, and in some cases 2, population bottlenecks. The 1st occurred during the 18th and 19th centuries as a result of commercial hunting that eliminated sea otters from much their native range and reduced surviving populations to small remnants. The 2nd bottleneck occurred when small numbers of otters were reintroduced, via trAuthorsShawn E. Larson, Ronald J. Jameson, James L. Bodkin, Michelle Staedler, Paul BentzenSea otter population structure and ecology in Alaska
Sea otters are the only fully marine otter. They share a common ancestry with the Old World land otters, but their route of dispersal to the New World is uncertain. The historic range of the species is along the northern Pacific Ocean rim, between central Baja California and the islands of northern Japan. Because they forage almost exclusively on bottom-dwelling marine invertebrates such as clams,AuthorsJames L. Bodkin, Daniel H. MonsonSea otter studies in Glacier Bay National Park and Preserve
Following translocations to the outer coast of Southeast Alaska in 1965, sea otters have been expanding their range and increasing in abundance. We began conducting surveys for sea otters in Cross Sound, Icy Strait, and Glacier Bay, Alaska in 1994, following initial reports (in 1993) of their presence in Glacier Bay. Since 1995, the number of sea otters in Glacier Bay proper has increased from aroAuthorsJames L. Bodkin, Kimberly A. Kloecker, George G. Esslinger, Daniel H. Monson, J.D. DeGroot, J. DohertyTemporal variations of natural and anthropogenic radionuclides in sea otter skull tissue in the North Pacific Ocean
Marine mammals being among the top predators in the food web tend to accumulate organic and inorganic contaminants from the environment. The body burden of contaminants in these species could reflect their foods and thus contaminant levels could serve as proxies on the changes of ecosystem. A pilot study was carried out to investigate the possibility of radionuclide leakage at Amchitka using a suiAuthorsM. Baskaran, G.-H. Hong, S. Dayton, James L. Bodkin, J.J.

We examined the potential role of food limitation in constraining the recovery of sea otters Enhydra lutris in Prince William Sound, Alaska, following the 'Exxon Valdez' oil spill. The spill resulted in the removal of a large number of sea otters in 1989, and as of 1998, the portion of the population in the heavily oiled northern Knight Island region had not fully recovered.

The otters (Mustelidae; Lutrinae) provide a unique look into the evolution of marine living by mammals. This is because most extant marine mammals have been so highly modified by long periods of selection for life in the sea that they bare little resemblance to their terrestrial ancestors. Marine otters, by contrast, are recent expatriates from terrestrial and freshwater habitats, and some speciesAuthorsJames A. Estes, James L.
