MM34A:
Discoveries in Viral Ecology and Microbial Adaptation to Extreme Environments Posters


Session ID#: 28338

Session Description:
Recent findings on the high incidence of viruses or lysogeny in marine habitats characterized by extreme conditions, from environments as diverse as sea ice, brines in frozen soils, oxygen deficient zones, deep-sea sediments and hydrothermal vents, suggest the potential for enhanced gene flow between organisms in such environments. The adaptive traits of marine organisms and how they acquire those traits is of fundamental interest across environments, but of particular interest in environments that may be extreme on long time scales, periodically exposed to extreme conditions or subject to exposure to extremes in future. To foster comparative analyses and mechanistic understanding, we seek contributions on any aspect of viral ecology and genetic adaptation to extremes of temperature, pressure, salinity or energy/nutrient availability, from the role of viruses in lateral gene transfers to the role of geochemical constraints and physical confinement on gene exchange between organisms.
