EP12A:
Impacts of Ecological Interactions on Marine Ecosystem Dynamics: New Insights from Theory, Models, and Field Measurements I


Session ID#: 37851

Session Description:
Ocean ecosystems make up the largest living space on the planet. Understanding the behavior, physiology, and evolution of marine organisms in the context of their chemical and physical environments and species interactions is key to advancing our understanding of community and ecosystem functioning across systems. Multiple general concepts in ecology have originated from pelagic systems, including ecological stoichiometry, trophic cascades, and the match/mismatch hypothesis. However, a fundamental hurdle in advancing our understanding of ecological processes in the ocean remains the traditional boundary between ecology and oceanography. In this session, we seek to bring together oceanographers and ecologists posing questions about ocean ecosystems, bridging empirical investigations with ecological theory and process models. We welcome both theoretical and empirical research addressing ecological interactions across a range of scales and trophic levels, with particular emphasis on the integration of field sampling, ecological theory, and/or modeling aimed to reveal processes structuring ocean ecosystems. We especially look to highlight recent advances since 2016.
