| Description |
Quinn will describe a study of salmon predation by bears in Alaska. The study looked at the controls on the number and proportion of salmon killed in a creek each year. Quinn will outline the observed patterns: 1. Bears kill a higher proportion of the salmon in narrow than wide streams. 2.The number of salmon killed reaches an asymptote at high salmon density. 3. Bears consume body parts to maximize energy density, not volume. 4. Bears are most selective when salmon are most available. Quinn...
