Published: 29 February 2024
...Alex R. Gunderson ABSTRACT The effects of climate change are often body size dependent. One contributing factor could be size-dependent thermal tolerance (SDTT), the propensity for heat and cold tolerance to vary with body size among species and among individuals within species. SDTT...

... fluctuations. For chill-susceptible insects, such as Drosophila , cold tolerance is tightly linked to ion and water homeostasis obtained through a regulated balance of active and passive transport. Active transport at low temperature requires a constant delivery of ATP and we therefore hypothesize that cold...

...Nicholas M. Teets; J. D. Gantz; Yuta Kawarasaki ABSTRACT Rapid cold hardening (RCH) is a type of phenotypic plasticity that allows ectotherms to quickly enhance cold tolerance in response to brief chilling (lasting minutes to hours). In this Review, we summarize the current state of knowledge...

While the ecological significance of RCH is well established, the mechanisms underlying RCH are still poorly understood. Previous work has demonstrated that RCH is regulated at the cellular level by post-translational signaling...
