This chapter describes the contribution of multifactorial experimental studies in understanding the decline of Steller sea lion (Eumetopias jubatus) populations in Alaska. It identifies the major causes of Stellar sea lion declines such as decreased adult survival, decreased juvenile survival, decreased fecundity, and increased emigration. It then discusses some of the proximate causes for population decline, such as direct killing, increased predation, and environmental change. It also describes laboratory experiments that test the potential role of nutritional stress in the decline of Steller sea lions.
