EP51B:
From Physics to Predators: Understanding Bottom-Up Forcing of Pelagic Ecosystems II


Session ID#: 37831

Session Description:
Physical oceanography is a fundamental determinant of micro- and macroecology in our oceans, driving vertebrate distributions and interactions through bottom-up processes. Understanding how oceanographic processes influence marine vertebrate distribution and ecology is not only of key interest to ecologists, but is also necessary for effective species conservation and management. A wealth of correlative studies have revealed the strong links between oceanography and vertebrate ecology, however holistic understanding of the mechanisms underlying these relationships remains limited due to the complex nature of these dynamic processes. The rapid advancement of animal tracking technologies, coupled with sophisticated ocean modeling and monitoring tools, now allow researchers to better interrogate these drivers. In this session we solicit contributions on established and potential mechanisms linking ocean biophysics to vertebrate distribution and ecology, from disciplines spanning physical oceanography to community ecology. The research shared in this session will highlight data sources, methods, and areas of opportunity to foster further cross-disciplinary research on marine physical-ecological systems.
