One way to address big-scale problems and processes is to use small-scale data to construct and test mechanistic models of events at higher levels of organization and at larger spatial scales. Even though this general approach to understanding ocean ecosystems underpins much of biological oceanography, it has not been so commonly used in efforts to understand the population and community dynamics of marine mammals. This chapter uses demographic and bioenergetic tools to explore difficult-to-observe predator-prey interactions in marine mammal communities. It aims to understand better the interactions of mammal-feeding killer whales with their prey species in the North Pacific region, particularly in the vicinity of the Aleutian archipelago.
