MM24A:
A Matter of Life and Death: The Role of Microbial Interactions in Mediating Biogeochemical Cycles II Posters


Session ID#: 29854

Session Description:
Marine microbes play essential roles in the structuring of marine food webs, and the movement of organic material and nutrients throughout the ocean. Increasingly, it is recognized that individual-level microbial interactions play an intrinsic role in controlling species diversity, community composition, and the fate of nutrient regeneration and carbon export. However, linking microbial interactions from the individual level to shifts in biogeochemistry has proven complex, often requiring a combination of experimental and theoretical approaches.

Within this interdisciplinary session, we invite abstracts that enhance our mechanistic understanding of how biological interactions (e.g. predator-prey, allelopathy, parasitism, viruses), between or among microbes, influence biogeochemical cycles in the ocean. Integrative approaches that connect scales – from individual interactions to the ecosystem level using laboratory, in situ or modelling studies are encouraged. This session will cover a broad range of topics, including how microbial interactions influence: growth promotion, induction of mortality, chemical communication, and changes in gene expression, as well as the incorporation of these interactions into ecosystem models.
