Without widespread and immediate changes in human values and activities, massive tracts of natural habitat will be degraded to the detriment of those ecosystems, ecosystem services, and many threatened taxa—in the oceans and elsewhere. Despite this, the conservation movement has yet to devote much attention to the intentional project of widespread norm change. By one logic, the ecosystem services concept offers a means of integrating meaningful conservation into decision making by diverse government and corporate actors, potentially normalizing conservation. But normalizing conservation would require not only the uptake of ecosystem-services concepts but also widespread changes in conservation practice and stewardship values—on a scale that far exceeds what we have witnessed to date.
Pinnipeds are a fascinating group of marine mammals that play a crucial role as apex predators and sentinels of the functioning and health of marine ecosystems. They are found in the most extreme environments from the Polar regions to the tropics. Pinnipeds are comprised of about 34 species, and of those at least 25% live permanently in tropical zones. This book reviews and updates current research on the biology, marine ecology, bio-monitoring, and conservation of tropical pinniped populations, including their behavior, anthropogenic stressors, and health. It also looks at challenges to be faced for the conservation of tropical pinnipeds, many of which are threatened species.
