J Exp Biol (2020) 223 (20): jeb231241.
Published: 19 October 2020
...Christian O. Chukwuka; Joanne M. Monks; Alison Cree ABSTRACT Understanding the interaction between upper voluntary thermal limit (VT max ) and water loss may aid in predicting responses of ectotherms to increasing temperatures within microhabitats. However, the temperature at which climate heating...

... was to investigate the stability of body temperature in large fish using data from field experiments. We measured the muscle temperatures of free-ranging whale sharks ( Rhincodon typus ), the largest extant fish globally, and investigated their ectothermic physiology and the stability of their body temperature...

...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...

Published: 7 May 2019
...Anne M. Treasure; Steven L. Chown ABSTRACT Ectotherms may respond to variable environmental conditions by altering their phenotypes. Phenotypic plasticity was initially thought to be beneficial to an organism's physiological fitness but several alternative hypotheses have been proposed with growing...

... of these mechanisms can be difficult to separate. In this study, we used the western fence lizard, Sceloporus occidentalis , as an ectothermic model to determine whether a reduction in metabolic rate is sufficient to resist muscle atrophy. We induced atrophy through sciatic denervation of the gastrocnemius muscle...

Following 4 months of hibernation, LDH activity is decreased in at least one species of frog ( St Pierre and Boutillier,2001 ). A study from the fish literature proposes that at cold temperature, LDH concentrations...
