Journal ArticleDOI
The circadian rhythm of body temperature.
TL;DR: This article reviews the literature on the circadian rhythm of body temperature and describes the typical pattern of oscillation under standard laboratory conditions, with consideration being given to intra- and interspecies differences.
Book
Avian Energetics and Nutritional Ecology
TL;DR: This chapter discusses avian energetics, ecology and evolution, and investigates the role of mitochondria in bird thermoregulatory responses and post-natal growth.
Journal ArticleDOI
Energy constraints on avian distributions and abundances
TL;DR: In this paper, a regression analysis reveals that the northern boundary metabolic rate (NBMR) is 2.45 times the basal metabolic rate, and that the NBMR to BMR ratio shows little interspecific variation.
Journal ArticleDOI
Natural hypometabolism during hibernation and daily torpor in mammals.
TL;DR: Hibernation and daily torpor are found in small mammals inhabiting temperate as well as tropical climates, which indicates that this behaviour is not primarily aimed for cold defense, instead points to a general role of hypometabolism, as a measure to cope with a timely limited or seasonal bottleneck of energy supply.

Delayed menarche and amenorrhea of college athletes in relation to age of onset of training.
Rose E. Frisch,Astrid V. Gotz-Welbergen,Janet W. McArthur,T E Albright,Jelia C. Witschi,Beverly A. Bullen,Jason Birnholz,Robert B. Reed,Howard Hermann +8 more
TL;DR: Training increased the incidence of oligomenorrhea and amenorrhea among both premenarche- and postmenarches-trained athletes, and metabolic and hormonal changes consequent to an increased lean/fat ratio may explain these findings.
