For almost 40 years, studies of whole-organism performance have formed a cornerstone of
evolutionary physiology. Although its utility as a heuristic guide is beyond question, and we …

Colour polymorphic species are model systems for examining the evolutionary processes
that generate and maintain discrete phenotypic variation in natural populations. Lizards …

We summarize thermal-biology data of 69 species of Amazonian lizards, including mode of
thermoregulation and field-active body temperatures (Tb). We also provide new data on …

Studies of thermal ecology and physiology (eg the change in performance with temperature)
provide critical data for predicting the potential responses of ectothermic organisms to …

Temperature variation throughout a species range can be extensive and exert divergent
spatiotemporal patterns of selection. The estimation of phenotypic differences of populations …

In this contribution, the aspects of reptile and amphibian speciation that emerged from
research performed over the past decade are reviewed. First, this study assesses how …

Warming climates are facilitating the range expansion of many taxa to habitats that were
formerly thermally inhospitable, including to higher latitudes and elevations. The potential for …

Sexual size dimorphism (SSD) is often assumed to reflect the phenotypic consequences of
differential selection operating on each sex. Species that exhibit SSD may also show …

Locomotor biomechanics faces a core trade-off between laboratory-based and field-based
studies. Laboratory conditions offer control over confounding factors, repeatability, and …

Climate change is rapidly altering the way current species interact with their environment to
satisfy life-history demands. In areas anticipated to experience extreme warming, rising …
