Principles of Insect Low Temperature Tolerance
TLDR
Insects, more than any other eukaryotic taxon, have evolved not only to survive but to flourish in a wide variety of thermal environments.
A Rapid Cold-Hardening Process in Insects
TLDR
An extremely rapid cold-hardening response was observed in nonoverwintering stages that confers protection against injury due to cold shock at temperatures above the supercooling point.
Continuous up-regulation of heat shock proteins in larvae, but not adults, of a polar insect
TLDR
A dichotomy in survival strategies exploited by this flightless midge at different stages of its life cycle is reported, possibly to facilitate proper protein folding in a cold habitat that is more thermally stable than that of the adults but a habitat subjected frequently to freeze-thaw episodes and bouts of pH, anoxic, and osmotic stress.
Low Temperature Biology of Insects: Index
TLDR
This work presents a meta-analyses of the macrophysiology and physiology of insect thermal adaptation to cold environments and the implications for pest management and climate change in the temperate zone.
Hibernation physiology, freezing adaptation and extreme freeze tolerance in a northern population of the wood frog
TLDR
Alaskan frogs differed from Ohioan frogs in retaining a substantial reserve capacity for glucose synthesis, accumulating high levels of cryoprotectants in brain tissue, and remaining hyperglycemic long after thawing.
Avoidance and tolerance of freezing in ectothermic vertebrates
TLDR
Although freeze avoidance and freeze tolerance generally are mutually exclusive strategies, a few species can switch between them, the mode used in a particular instance of chilling depending on prevailing physiological and environmental conditions.
Preservation of reproductive behaviors during modest cooling: rapid cold-hardening fine-tunes organismal response
TLDR
Data demonstrate that RCH serves to constantly fine-tune an insect's physiological state to match slight changes in environmental temperature, and is not restricted to cryoprotection and survival in the cold but also preserves more subtle behaviors, such as courtship, at moderate to high temperatures throughout the year.
Cold-Shock Injury and Rapid Cold Hardening in the Flesh Fly Sarcophaga crassipalpis
TLDR
The rapid increase in cold tolerance correlates with concomitant increases in hemolymph osmolality and glycerol levels, which suggests a novel role for glycersol in protecting insects against injury resulting from cold shock, although other unidentified mechanisms may be involved in this response.
Rapid cold-hardening protects Drosophila melanogaster from cold-induced apoptosis
TLDR
The hypothesis that the RCH response protects against cold-shock-induced apoptosis in Drosophila melanogaster is supported.
