Contrasting western Steller sea lion and northern fur seal population trends in Alaska / Brian Fadely, and 7 others.
Title: | Contrasting western Steller sea lion and northern fur seal population trends in Alaska / Brian Fadely, and 7 others. |
Author(s): | Fadely, Brian. |
Date: | 2006. |
In: | Alaska Fisheries Science Center. Quarterly Report. (2006.), (1) (2006) |
Abstract: | Compares population trends of Steller sea lions (Eumetopias jubatus) and northern fur seals (Callorhinus ursinus) by standardising counts to 1976 abundance estimates for each species and scaling subsequent abundance estimates accordingly. Finds that, although recent population increases are encouraging for both species, there are strong regional differences in trends, which may relate to temporal and spatial habitat segregation within and between species. |
