▪ Abstract Animal species have evolved different diel activity rhythms that are of adaptive
value. Theory suggests that diel temporal partitioning may facilitate coexistence between …

In modern eutherian (placental) mammals, brown adipose tissue (BAT) evolved as a
specialized thermogenic organ that is responsible for adaptive non-shivering thermogenesis …

Circadian rhythms influence most of our life activities, notably getting up and going to sleep
every day. The new edition of this book delves into the mechanisms surrounding how these …

This article reviews the literature on the circadian rhythms of body temperature and whole-
organism metabolism. The two rhythms are first described separately, each description …

Considerable research is aimed at developing predictions of ecosystem responses to
climate change, focusing on the spatial scale, such as range shifts and contractions, as well …

Most organisms (including humans) developed daily rhythms in almost every aspect of their
body. It is not surprising that rhythms are also related to affect in health and disease. In the …

Animals should time activities, such as foraging, migration and reproduction, as well as
seasonal physiological adaptation, in a way that maximizes fitness. The fitness outcome of …

Acclimation, in contrast to evolutionary adaptation, is a “within life time phenotypic
adaptation” resulting in a widening of the dynamic regulatory range of body temperature …

Evolutionary plasticity is limited, to a certain extent, by phylogenetic constraints. We asked
whether the diel activity patterns of animals reflect their phylogenies by analyzing daily …

Seasonal adjustments in body mass and thermogenesis are important for the survival of
small mammals during acclimatization in the temperate zone. To determine the contributions …
