Theoretical models predict that selection on reaction norms should depend on the relative
frequency of environmental states experienced by a population. We report a laboratory …

How thermal tolerance estimated in the laboratory can be extrapolated to natural settings
remains a contentious subject. Here, we argue that the general premise that a single …

Most ectotherms follow the temperature‐size rule (TSR): in cold environments individuals
grow slowly but reach a large asymptotic length. Intraspecific competition can induce plastic …

The impact of anthropogenic climate change on terrestrial organisms is often predicted to
increase with latitude, in parallel with the rate of warming. Yet the biological impact of rising …

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) …

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

The mean and variance of environmental temperature are changing as a consequence of
human activities. Ectotherms are sensitive to these temperature changes in the short term …

Climate warming is predicted to cause large-scale extinctions, particularly of ectothermic
species. A striking difference between tropical and temperate ectotherms is that tropical …

The ability to respond evolutionarily to increasing temperatures is important for survival of
ectotherms in a changing climate. Recent studies suggest that upper thermal limits may be …

The ability to predict the consequences of fluctuating environments on species distribution
and extinction often relies on determining the tolerances of species or genotypes in different …
