Jody W. Deming’s Ecosystem

University of Washington, School of Oceanography



Our research interests:

Adaptations of marine microorganisms - Bacteria and Archaea (Collins et al., 2010; Kellogg and Deming, 2014), and their viruses (Colangelo-Lillis and Deming, 2012) and sea-ice algae (Krembs et al, 2011) - to living within physical support structures, including frost flowers (Bowman and Deming, 2010; Bowman et al., 2014) shown above on the right, sea ice, particle aggregates and sediments, especially as they influence carbon and other elemental cycles (Kellogg et al., 2011).

Cold adaptation in marine microorganisms and relevance to polar geochemistry and ecology (e.g., Canadian Flaw Lead System Study, CFL; Nansen Amundsen Basins Observational System, NABOS; Canadian Arctic Shelf Exchange Study, CASES; International Northwater Polynya Study, NOW)

Limits of microbial life, especially in ice, as they relate to astrobiology (UW Astrobiology Program), biotechnology and bioremediation (UW Marine Bioremediation Program). See some of our recent work featured at these UW School of Oceanography links: Frost Flowers Foster Microbes; Bacteria in Ice.

Role of benthic bacteria in biogeochemical cycles and ecosystems, from coastal to deep-sea environments (DGoMB; Deming and Carpenter, 2008)

Hydrostatic pressure in the evolution and ecology of marine bacteria, especially at very cold (in deep-sea and polar environments) and hot (at hydrothermal vents) temperatures.  See Tamburini et al. (2013) in Environmental Microbiology.
