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

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

This paper reviews the literature on the circadian rhythm of body temperature (CRT). The

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 paper investigates the utility of the Lomb–Scargle periodogram for the analysis of
biological rhythms. This method is particularly suited to detect periodic components in …

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 …

Photoperiodism is the ability of plants and animals to measure environmental day length to
ascertain time of year. Central to the evolution of photoperiodism in animals is the adaptive …

This book presents evidence that infection is cyclical with the seasons, and that this
phenomenon is mirrored in cycles of immune function. The book identifies the mechanisms …
