The ecologic role of marine mammals is explored in this chapter, including food and the feeding relationships of marine mammals and the effects of change on the dynamics of marine ecosystems. Also considered is the effect of humans on marine mammal communities, ranging from oil spills and contamination of the ocean with heavy metals to diseases and global climate change and loss of habitat. Finally, conservation efforts such as captive breeding, provision of critical habitat, and relocation and recovery programs are evaluated.
