MM12A:
Marine Microbes in the Omics Epoch: Unveiling Their Critical Roles in the Pelagic and Benthic Environments II

Session ID#: 92936

Session Description:
Marine microorganisms - bacteria, viruses, phytoplankton, and protists have diverse interactions that  define large-scale processes, such as nutrient cycling, gas fluxes with the atmosphere, and energy flow through marine food webs. The complexity of microbial communities in ocean habitats, including planktonic, benthic and host-associated environments demands deeper exploration in order to unveil the critical roles that microbes play in shaping marine ecosystems. Symbiosis (i.e., mutualism, parasitism, commensalism), predation, mixotrophy, allelopathy and competition are some of the complex biological interactions that can significantly drive the ecology and evolution of these important microbial players. Advances in molecular technologies (genomics, metabolomics, genetic engineering), cutting-edge methods in microbiology (microfluidics, microscopy), laboratory model systems development, time series studies and modeling offer new ways to describe the linkages between specific microbial players and their surrounding environment. We invite studies that investigate these wide-ranging interactions, from microbe-microbe, microbe-organic matter to host-microbe interactions, to further explore microbial impacts on trophic transfer of chemical compounds, atmospheric gas fluxes, transformations of organic matter and nutrients, biogeochemical cycling and ecosystem health. Studies that develop emerging technologies and models that shed light to these cryptic interactions are also encouraged.
