Seasonal lipid contents of Antarctic microarthropods
A technique for the accurate determination of lipid content of very small quantities of biological tissue was applied to two Antarctic oribatid mites,Alaskozetes antarcticus andHalozetes belgicae, and a collembolan,Cryptopygus antarcticus. Analysis of monthly samples of the three species, collected...
