Abstract There has been a growing concern over the last few decades about theeffects of environmental stress, including anthropogenic impacts, onmarine mammals. This paper provides an overview of the wide range ofanthropogenic stressors that marine mammals may encounter and the levelof understanding on their potential effects. Sources of stress andphysiological responses of the animals are explored. Many of the lifehistory traits of marine mammals (i.e., long-life spans, late maturity,relatively low reproductive potential, and feeding high in the foodchain), make them susceptible to various anthropogenic stressors. Sincemarine mammals are exposed to a diverse array of multiple stressors,this paper focuses on three case studies (acute and chronic effects fromoil spills; chronic effects from environmental contaminants, andfishery-induced stress) to emphasize potential relevant hazards and toprovide a perspective on the use of marine mammals in assessingecosystem health. Additional research to enhance our understanding ofstress on marine mammals and to provide the science needed to guidemanagement decisions is recommended.
