High-latitude environments are challenging for terrestrial ectotherms because short and cool
active seasons generally limit the time available for foraging and growth, thereby negatively …

Temperature profoundly impacts both the phenotypes and distributions of organisms. These
thermal effects exert strong selective pressures on behaviour, physiology and life history …

The metabolic distinction between endotherms and ectotherms is profound. Whereas the
ecology of metabolic rates is well studied, how endotherms evolved from their ectothermic …

Thermal performance curves are an example of continuous reaction norm curves of common
shape. Three modes of variation in these curves—vertical shift, horizontal shift, and …

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 …

The temperature–size rule is a common pattern of phenotypic plasticity in which higher
temperature during development results in a smaller adult body size (ie a thermal reaction …

Methods: We used a split sib-family experimental design with two food treatments (collard
leaves and artificial diet) and four test temperatures (11, 23, 35 and 40 C), and measured …

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

Tradeoffs have played a prominent role in the development of theories describing the
evolution of reaction norms. Different classes of tradeoffs are known to constrain the …

Thermal performance curves (TPCs) have been estimated in multiple ectotherm species to
understand their thermal plasticity and adaptation and to predict the effect of global warming …
