MM44D:
Viruses in Aquatic Ecosystems: Diversity, Biogeochemistry, and Host Interactions Posters


Session ID#: 9328

Session Description:
Viruses are quantitatively significant components of aquatic ecosystems, where they cause mortality of organisms from bacteria to whales. Research over the past 25 years has highlighted their critical roles in aquatic biogeochemical cycles, maintaining or enhancing the biodiversity of their hosts, and in gene exchange between individuals and populations of microorganisms. Aquatic viruses are also incredibly diverse as free particles in virioplankton, as integrated temperate viruses and in association with the tissues of metazoans and higher animals. In this session, we seek submissions addressing the abundance and diversity of viruses across aquatic ecosystems and in association with hosts, and the impacts of viruses on host ecology and host-driven biogeochemistry. We also welcome submissions describing new techniques for the study of viral ecology in aquatic ecosystems, and those that address viral discovery.
