| Description: |
Capture, handling, and examination procedures employed were approved by the Institutional Animal Care and Use Committee (IACUC) of the Alaska Science Center (ASC) and the United States Geological Survey and were authorized by the United States Fish and Wildlife Service (USFWS) under permit number 766818, except those conducted within California under USFWS permit number 672624 and IACUC permit #Tink1510 with University of California Santa Cruz. Special thanks to D. Douglas, C. Kolden, K. Miles, S. Newsome, L. Nichol, W. Perry, J. Sarrinen, V. VonBiela, J. Yee, and C. Zimmerman for their contributions to the United States Department of the Interior (DOI) on the Landscape: Pacific Nearshore Program. It was a large effort to capture and sample 334 animals. ; International audience ; Sea otters, Enhydra lutris, were once abundant along the nearshore areas of the North Pacific. The international maritime fur trade that ended in 1911 left 13 small remnant populations with low genetic diversity. Subsequent translocations into previously occupied habitat resulted in several reintroduced populations along the coast of North America. We sampled sea otters between 2008 and 2011 throughout much of their current range and used 19 nuclear microsatellite markers to evaluate genetic diversity, population structure, and connectivity between remnant and reintroduced populations. Average genetic diversity within populations was similar: observed heterozygosity 0.55 and 0.53, expected heterozygosity 0.56 and 0.52, unbiased expected heterozygosity 0.57 and 0.52, for reintroduced and remnant populations, respectively. Sea otter population structure was greatest between the Northern and Southern sea otters with further structuring in Northern sea otters into Western, Central, and Southeast populations (including the reintroduced populations). Migrant analyses suggest the successful reintroductions and growth of remnant groups have enhanced connectivity and gene flow between populations throughout many of the sampled Northern ... |
