Investigation of the effect of short-term variation in soil moisture and soil temperature on nematode anhydrobiosis as part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project. The percent of anhydrobiotic (coiled) nematodes with relation to soil moisture and temperature was determined. The study began at 1030 on 10 December 1997 and ended on 11 December 1997. The samples were taken at 0, 6, 12, 18, and 24 hrs. Samples were collected in the south side of the Lake Hoare, Taylor Valley, Victoria lands, Antarctica

In the Antarctic Dry Valleys, soil polygons are prominent features of the landscape and may be key units for scaling local ecological information to the greater region. We examined polygon soils in each of the 3 basins of Taylor Valley, Antarctica. Our objectives were to characterize variability in soil biogeochemistry and biodiversity at local to regional scales, and to test the influence of soil properties upon invertebrate communities.
