The theory of optimal foraging and its relation to central foraging was examined by using the beaver as a model. Beaver food choice was examined by noting the species of woody vegetation, status (chewed vs. not-chewed), distance from the water, and circumference of trees near a beaver pond in North Carolina. good luck on your test tomorrow

"WebTo analyze the behavior of a sit-and-wait (ambush) predator whose optimal foraging strategy is to maximize the energy that it gains. Theory: Behavioral ecology deals with the evolutionary mechanisms for animal behavior due to pressure from the ecological system. This investigates how the behavior of an organism is related to the ecosystem. " - Handling time ecology
