Seasonal Effects on Soil Biota

Summary

Abstract: 

Investigation of the effect of long-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 season was determined.
 
The study took place on three separate dates during the 1997-1998 austral summer: 21 November 1997, 16 December 1997, and 13 January 1998, samples were gathered at the south side of the Lake Hoare

Date Range: 

November 21, 1997 to January 13, 1998
