ME14E:
Ocean Epigenetics: What Are We Learning As We Explore Epigenetics in Marine Organisms and Ecosystems? I Posters

Session ID#: 84847

Session Description:
The role of epigenetic mechanisms (e.g., DNA methylation, changes in chromatin structure, and small RNAs) in an ecological and environmental context has become increasingly studied in a variety of non-model metazoans. In marine molecular ecology, epigenetic mechanisms have been examined in the context of adaptation, in response to abiotic stress, in transgenerational plasticity, and, generally as a means by which the environment might alter gene expression.

For this proposed OSM session, we plan to highlight emerging insight and new discoveries in epigenetics in marine metazoans. The session will include data from a diversity of marine habitats (e.g., studies in coral reefs and kelp forest environments), along with studies focused on anthropogenic activities such as aquaculture, invasion biology, and the impacts of toxicants such as microplastics in the marine environment (e.g., biomonitoring tool development and application).

Overall, although the session addresses a specific area of marine molecular ecology, the importance of epigenetics in a range of environmental settings, from coral bleaching events to marine heat waves, renders this session of general interest to the OSM community, and additionally, would engage an international audience, given the broad scientific interest in epigenetics and its application in marine systems.
