Genetic variation in sea otters (Enhydra lutris) from the North Pacific with relevance to the threatened Southwest Alaska distinct population segment
For the sea otter (Enhydra lutris), genetic population structure is an area of research that has not received significant attention, especially in Southwest Alaska where that distinct population segment has been listed as threatened since 2005 pursuant to the U.S. Endangered Species Act.

The 14 sampling locations formed six geographic associations in clustering and ordination analyses that likely correspond to remnant population lineages: 1) Southcentral Alaska, 2) Kodiak and North Alaska Peninsula, 3) South Alaska Peninsula and Bristol Bay, 4) Eastern Aleutian, 5) Western Aleutian, and 6) the Commander Islands.
