Abstract Theory predicts the emergence of generalists in variable environments and
antagonistic pleiotropy to favour specialists in constant environments, but empirical data …

Body temperature influences the performance and fitness of ectotherms. How thermal
sensitivity responds to selection for resistance to high temperature is broadly relevant in …

Thermal tolerance is an important factor influencing the distribution of ectotherms, but we still
have limited understanding of the ability of species to evolve different thermal limits. Recent …

The two foremost hypotheses on the evolutionary constraints on an organism's thermal
sensitivity–the hotter‐is‐better expectation, and the specialist–generalist trade‐off–have …

Polyphenism, the expression of discrete alternative phenotypes, is often a consequence of a
developmental switch. Physiological changes induced by a developmental switch potentially …

Climate change is resulting in a radical transformation of the thermal quality of habitats
across the globe. Whereas species have altered their distributions to cope with changing …

Despite decades of research on the evolution of thermal physiology, at least one
fundamental issue remains unresolved: whether the maximal performance of a genotype …

Ectothermic animals exhibit two distinct kinds of plasticity in response to temperature:
Thermal performance curves (TPCs), in which an individual's performance (eg, growth rate) …

Temperatures are increasing due to global changes, putting biodiversity at risk. Organisms
are faced with a limited set of options to cope with this situation: adapt, disperse or die. We …

Animals and plants often exhibit narrow ranges of thermal preference in variable
environments; fitness-enhancing activities such as reproduction and growth tend to be …
