Soil Effects on Anhydrobiosis of Nematodes

Summary

Abstract: 

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 in the austral summer of 1996/1997. Locations on the south sides of both the Lake Hoare and Fryxell. Also, at a moss site near the Canada Glacier.  Samples gathered on Jan 1st 1997

Date Range: 

January 1, 1997 to January 2, 1997
