... to lipid and purine metabolism were downregulated. The observed patterns of expression indicate a rapid recovery after chill coma, suggesting an acute differential transcriptional response during recovery from chill coma and return to baseline expression levels within an hour with no long-term gene...

...Harriet R. Goodrich; Chris M. Wood; Rod W. Wilson; Timothy D. Clark; Katja B. Last; Tobias Wang ABSTRACT The physiological processes underlying the post-prandial rise in metabolic rate, most commonly known as the ‘specific dynamic action’ (SDA), remain debated and controversial. This Commentary...

... of insecure access to food can lead to changes in weight, motivation and cognition. Some of these studies account for changes in weight through changes in metabolism, while others observe increases in feeding and motivation to work for food. It has been proposed that weight gain is an adaptive response...

.... In ectotherms, changes to both metabolism and behaviour can help alleviate thermal stress. Nonetheless, no study in any ectotherm has yet empirically investigated how changing temperatures affect among-individual differences in the associations between these traits. Using the beadlet anemone ( Actinia equina...

In alien populations of anurans, dispersal and fitness-related traits such as endurance, burst performance and metabolism are key to their success...

Then, using historical tag–recapture data, we estimated the movement propensity and migratory pace of autumn migrants using computer simulations and subsequently calculated energy expenditure. Finally, we estimated the energy use of monarchs based on these tag–recapture...

However, the direct measurement of total metabolic energy savings during collective motion compared with solitary movement over a range of speeds has yet to be documented. In particular, longer duration and higher speed collective motion must involve both...

... swimming speed ( U crit ) of male offspring was greatest when both parents were raised at 28°C, and warmer fathers produced daughters with greater U crit . Similarly, warmer fathers produced sons and daughters with greater metabolic capacity. We show that the thermal variation experienced by parents can...

Yet, the contribution of key metabolic hormones, i.e. thyroid hormones (THs), has been largely ignored. We recently showed that in contrast to predictions, exposure to elevated prenatal THs increased...
