This chapter uses a combination of models from behavioral and population ecology to address certain aspects of community dynamics. It aims to show how the synthesis of two different scientific traditions (the literature on prey choice by predators and the literature on population dynamics) can lead to new understandings and new empirical challenges. An evolutionary understanding of feeding behavior turns out to be a good starting point for combining the traditions of prey choice by predators and population dynamics. The model provides a quantitative basis for the qualitative pattern of decline of several subpopulations of harbor seal, sea lion, and sea otter.
Keywords: behavioral ecology, population ecology, population dynamics, prey choice, harbor seal, sea otter
