Survival and water loss in some Antarctic arthropods
Seven species of Antarctic micro-arthropods (4 mites and 3 collembolans) were examined to determine their resistance to dehydration and their survival under dry conditions. Water loss at r.h. 5% at temperatures in the range −10 to 45°C was measured gravimetrically using a recording micro-balance. Su...
