Ecophysiological studies on arthropods from Spitsbergen
The cold-hardiness, high temperature tolerance and metabolic activity of summer specimens of staphylinid beetles (Atheta graminicola), collembolans (Onichiurus groenlandicw), spiders (Erigone arcrica), and prostigmatid mites (Molgus linoralb) from Spitsbergen were investigated. The animals displayed...
