MM21A:
Microbial Interactions in Ocean Ecosystems: Ecology to Biogeochemistry I


Session ID#: 11425

Session Description:
Integration of observational and manipulative techniques are increasingly allowing scientists to study organismal interactions at a wide range of spatial and temporal scales.  These approaches are revealing the diversity of interactions that occur in natural populations including competition and predation but also facilitation. In this session we encourage submissions focused on how microbes interact with other taxa (e.g. microbe-microbe and microbe-metazoan).  This session is intended to explore questions related to the interactions that allow organisms to outsource specific functions or that may be altered by changing environmental conditions, for example interactional shifts from mutualism to competition.  We hope to bring together a wide range of researchers including ecologists and biogeochemists to discuss the important role interactions play in structuring the diversity and productivity of marine microbes and their influence on biogeochemical cycling.
