The control of ice formation and presence of hemolymph cryoprotectants may contribute to C. monstrosa freeze tolerance and overwintering survival.
Reversing sodium differentials between the hemolymph and hindgut speeds chill coma recovery but reduces survival in the fall field cricket, Gryllus pennsylvanicus.

While a reduced [Na+] differential helps crickets recover from short-term cold exposure, an increased gut Na+ load itself appears to carry longer-term costs and promotes irreversible chilling injury.
Loss of ion homeostasis is not the cause of chill coma or impaired dispersal in false codling moth Thaumatotibia leucotreta (Lepidoptera: Tortricidae).

Testing the hypothesis that poor activity and dispersal in FCM is caused by delayed or perturbed recovery of ion and/or water homeostasis after chilling for handling and transport prior to field release finds no evidence that water and ionHomeostasis are lost by the moths in chill coma and concludes that reduced disperseal in field-released moths is not direct a consequence of the costs of re-establishment of homeOSTasis.
De novo assembly and characterisation of the transcriptome of the Beringian pseudoscorpion
This study yields the first transcriptome of a Beringian arthropod, providing important sequence information that will allow future investigation of how W. asiaticus survives in Canadian polar environments, and identifies 1100 transcripts encoding proteins associated with stress tolerance in these pseudoscorpions.

The transcriptome provides evidence for distinct roles and responses of fat body and flight muscle during diapause in the Colorado potato beetle, and provides testable hypotheses for biological processes that appear to drive diappause phenotypes in insects.
