Investigation of the effect of hydrological and biogeochemical linkages in the transition zone between streams and surrounding soils on invertebrate community structure as part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project. The invertebrate community structure with relation to soil moisture, salinity, and chlorophyll-a was determined. The study took place on 28 November 1997 and 31 December 1997 in the Von Guerard Stream/Harnish Creek network.

Investigation of the variation in soil biota and soil properties across the McMurdo Dry Valleys as part of the McMurdo Dry Valleys Long Term Ecological Research (LTER) project. The moisture content of soil samples which are collected for organism extraction and identification is determined. This study was carried out in the austral summer 1993/1994

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 nematodes with relation to soil moisture and temperature was determined. The study began at 0930 on 22 December 1997 and ended on 23 December 1997. The samples were taken at 0, 6, 12, 18, and 24 hrs.

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, temperature, and salinity 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 Lake Hoare

Concerns over environmental disturbance in the McMurdo Dry Valleys are increasing with increasing foot traffic from tourists and scientist. The effect of pedestrian disturbance were monitored by comparing the species composition, depth distribution and soil properties between adjacent high-, low- and no- traffic sites. This study began in the austral summer 1995/1996.
