Temporal resolution of cold acclimation and de‐acclimation in the Antarctic collembolan, Cryptopygus antarcticus
Abstract The Antarctic collembolan, Cryptopygus antarcticus (Willem), can switch its supercooling point (SCP) between ‘winter’ and ‘summer’ modes of cold hardiness over a matter of hours. High resolution temporal scaling of the acquisition and loss of cold hardiness is undertaken by assaying changes...
