MM003:
Coastal ecosystem exometabolites: linking the composition of dissolved organic matter to biological structure and process in nearshore habitats


Session ID#: 28743

Session Description:
Coastal ecosystems are complex zones of interaction among diverse habitats, including benthic, pelagic, fluvial and groundwater. All of these aquatic systems cycle dissolved organic matter, a portion of which is recently produced extracellular metabolites. Current advances in chemistry, genomics and ecosystem science have converged to demonstrate that these exometabolites are highly reactive and that the cycling of these compounds is central to structuring communities and ecosystem processes. The purpose of this session is to understand the factors that dictate the composition, reactivity and fate of different sources of organic matter in the coastal ocean, with particular attention to the dynamics of organismal exometabolites. Bio(geo)chemical studies on exometabolite production and structure are encouraged to be placed in the context of organisms and ecosystems: How do changes in community structure and ecosystem processes alter these compounds and how do these compounds influence communities? Because of the direct interface between microbial communities and exometabolites in aquatic systems, the microbiology of these interactions will be a central theme, but we encourage submissions of broader perspectives incorporating communities from primary producing  macroorganisms to higher trophic level consumers.
