Abstract/Summary

During storage of the collembolan Cryptopygus antarcticus Willem at +5°C over 387 d, both respiration and metabolic rates of size class V and IV individuals declined significantly. For pooled data for adults of both size classes this decline was calculated as: log10 MR=2.359-0.145 log10 T (where MR: metabolic rate in μ l O2 g-1 h-1 and T: time in d). No differences were detected between the sexes, but a significant difference (P < 0.05) in metabolism existed between fresh animals measured at the start of the storage experiment and earlier in the austral summer at Signy Island. The respiration and metabolic rates of the stored individuals were similar to those from earlier measurements made in the UK on individuals which had been subjected to similar treatment. It is suggested that the metabolic decline is an adaptation to constant temperature unrelated to the nutritional conditions. Short- and long-term metabolic adaptation is discussed in relation to studies on mites, nematodes and other invertebrates.
