How crickets become freeze tolerant: the transcriptomic underpinnings of acclimation in Gryllus veletis

J Toxopeus, LE Des Marteaux, BJ Sinclair - Comparative Biochemistry and …, 2019 - Elsevier
Some ectotherms can survive internal ice formation. In temperate regions, freeze tolerance
is often induced by decreasing temperature and/or photoperiod during autumn. However …
