ME44A:
Advances in the Ecology, Behavior, Physiology, or Conservation of Marine Top Predators IV Posters

Session ID#: 74850

Session Description:
Top predators are a vital part of the marine ecosystem, and as such, their ecology, behavior and physiology can influence important processes such as trophic interactions, carbon flow, and nutrient recycling. Virtually all top predators have a history of over-exploitation or they have special management status because of their sensitivity to marine industrial activities and other human uses (e.g., bycatch, shipping, resource exploration/extraction). Basic research on top predators often focuses on gaps in our understanding of their ecology, but unlike many other branches of biological oceanography, research can also be motivated directly by management and conservation needs. This session will focus on studies of the ecology, behavior, and physiology of marine top predators that either advance our scientific understanding or support the conservation of these important taxa. Because Ocean Sciences provides a unique forum for marine ecologists, marine biologists, and oceanographers to interact, we seek contributions from researchers studying a wide variety of taxa, including fish, squid, reptiles, seabirds, and marine mammals, from anywhere in the world’s oceans.
