Published: 4 December 2023
...Kamron Kayhani; Felipe S. Barreto ABSTRACT Determining the mechanisms by which organisms evolve thermal tolerance is crucial to predicting how populations may respond to changes in local temperature regimes. Although evidence of relationships between mitochondrial background and thermal adaptation...

...Ian A. Bouyoucos; Alyssa M. Weinrauch; Ken M. Jeffries; W. Gary Anderson ABSTRACT Thermal tolerance and associated mechanisms are often tested via the critical thermal maximum (CT max ). The agitation temperature is a recently described thermal limit in fishes that has received little mechanistic...
