Many organisms are shrinking in size in response to global warming. However, we still lack
a comprehensive understanding of the mechanisms linking body size and temperature of …

Research addressing the effects of global warming on the distribution and persistence of
species generally assumes that population variation in thermal tolerance is spatially …

Aim Understanding the mechanisms behind broad‐scale gradients in animal body size
remains challenging. In contrast to endotherms, the extent to which biophysical properties of …

Aim Many ectotherms are at risk from climate change as temperatures are increasingly
exceeding their thermal limits. Many evaluations of the vulnerability of ectotherms to climate …

Body size affects the body temperature of an ectotherm by altering both heating rates and
the microclimate experienced. These joint effects are rarely considered in the analyses of …

Quantifying intraspecific variation in heat tolerance is critical to understand how species
respond to climate change. In a previous study, we recorded variability in critical thermal …

Ectotherms utilise a complex array of behavioural and physiological mechanisms to cope
with variation in suboptimal thermal environments. However, these mechanisms may be …

The widespread observation that heat tolerance is less variable than cold tolerance ('cold‐
tolerance asymmetry') leads to the prediction that species exposed to temperatures near …

Lizards are considered vulnerable to climate change because many operate near their
thermal maxima. Exposure to higher temperatures could reduce activity of these animals by …

Rising global temperatures are predicted to impact organisms in diverse ways. For
ectotherms, recent broad‐scale analyses have predicted global patterns of vulnerability to …
