The whole‐body (tachymetabolic) endothermy seen in modern birds and mammals is long
held to have evolved independently in each group, a reasonable assumption when it was …

Endothermy is a conspicuous and important adaptation in birds. Even though juvenile and
adult birds are endothermic and maintain a constant, high body temperature by means of …

Sound is an essential source of information in many taxa and can notably be used by
embryos to programme their phenotypes for postnatal environments. While underlying …

Human-induced climate change is increasing the frequency, duration, and intensity of heat
waves and exposure to these extreme temperatures impacts individual physiology and …

Heat waves are predicted to be detrimental for organismal physiology with costs for survival
that could be reflected in markers of biological state such as telomeres. Changes in early life …

Thyroid hormones are key regulators of development and metabolism in vertebrates. During
the nestling period, young of altricial species transition from an ectothermic phenotype to an …

Most of the heat that is released in the vertebrate body is produced in the muscles during
contractile (during movement or trembling) and noncontractile (without muscle activity) …

How the accelerating pace of global warming will affect animal populations depends on the
effects of increasing temperature across the life cycle. Developing young are sensitive to …

Chickens experience rapid change in their physiology and metabolism during hatching. We
propose that thyroid hormones play a major role in regulating the developmental changes …

The 'membrane pacemaker'hypothesis proposes a biochemical explanation for among-
species variation in resting metabolism, based on the positive correlation between …
