MARC recordGeographical variation in Steller sea lion prey quality in Alaska / Lawrence Schaufler, Elizabeth Logerwell, Johanna Vollenweider.
| Title: | Geographical variation in Steller sea lion prey quality in Alaska / Lawrence Schaufler, Elizabeth Logerwell, Johanna Vollenweider. |
| Author(s): | Schaufler, Lawrence. Logerwell, Elizabeth. Vollenweider, Johanna. |
| Date: | 2006. |
| Publisher: | Fairbanks, AK: Alaska Sea Grant College Program |
| In: | Sea lions of the world : proceedings of the symposium Sea Lions of the World : Conservation and Research in the 21st Century, September 30-October 3, 2004, Anchorage, Alaska, USA. (2006.), |
| Abstract: | Examines hypothesis that nutritional stress is major factor of decline in Steller sea lion (Eumetopias jubatus) populations of western stock and possibility that western stock sea lions encounter prey of significantly lower quality than those from eastern stock. Finds that mean energy density for 22 forage species from south-eastern Alaska was greater than that of 15 species from Aleutians, but that variations could be attributed to size differences among fish sampled from regions as well as species composition and controlled seasonal differences. |
