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

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 …

Species may exhibit similar thermal tolerances via either common ancestry or environmental
filtering and local adaptation, if the species inhabit similar environments. We ask whether …

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 …

Thermal trait variation is of fundamental importance to forecasting the impacts of
environmental change on lizard diversity. Here, we review the literature for patterns of …

One of the fundamental goals in macroecology is to understand the relationship among
species' geographic ranges, ecophysiology, and climate; however, the mechanisms …

Aim Temperature influences most components of animal ecology and life history–but what
kind of temperature? Physiologists usually examine the influence of body temperatures …

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 …

Populations at the warm range margins of the species distribution may be at the greatest
risks of extinction from global warming unless they can tolerate extreme environmental …

Tropical ectotherms are regarded as being especially threatened by global warming, but the
extent to which populations vary in key thermal physiological traits is little known. In general …
