Little is known about the distribution and functional importance                of nematodes in the snow-free dry valleys of Antarctica.  The dry               valleys have been compared with other desert regions of the                     world.  Adaptations to low moisture availability and extremes of                temperature are required of organisms attempting to function in                 stressful desert ecosystems.  This project will examine and                     compare the structure of nematode communities in the dry valleys                of Antarctica with those of better studied desert ecosystems.                   The distribution and trophic structure of nematode communities                  will be determined for three dry valleys at the peak of the                     austral summer.  Nematode distribution, abundance, and species                  composition will be related to soil physical and chemical                       properties including organic C, nitrogen, salinity, pH, and                     microbial number and biomass.  The energy supply of soil will be                augmented with sugar to determine if nematode numbers are energy                limited or are limited by abiotic factors influencing survival.                 Nematode adaptations to low soil moisture (anhydrobiosis) and to                low temperature (cryptobiosis) will be studied under controlled                 laboratory conditions.  Wind dispersed nematodes will be studied                in Wright Valley by trapping wind dispersed nematodes along the                 axis of the valley.
