The importance of prey aggregations to the distribution of Brünnich's guillemots in Storfjorden, Svalbard / Fridtjof Mehlum, George L. Hunt, Zygmunt Klusek, Mary Beth Decker, Nina Nordlund.
Title: | The importance of prey aggregations to the distribution of Brünnich's guillemots in Storfjorden, Svalbard / Fridtjof Mehlum, George L. Hunt, Zygmunt Klusek, Mary Beth Decker, Nina Nordlund. |
Author(s): | Mehlum, Fridtjof. Hunt, George L. Klusek, Zygmunt. Decker, Mary Beth. Nordlund, Nina. |
Date: | 1996. |
In: | Polar Biology. (1996.), Vol. 16(8) (1996) |
Abstract: | Authors studied influence of distribution of prey and hydrographic fronts on foraging Uria lomvia in July 1992. Two large breeding colonies totalling 540 000 birds were adjacent to study area. Within area, most foraged on side of fjord where was weak subsurface front between warm Atlantic water from south and cold Arctic water. Food samples contained primarily crustaceans and Polar cod. Numbers of foraging guillemots correlated strongly with strengths of acoustic echoes of aggregated type from prey. |
