Basal rate of metabolism (BMR) is a physiological parameter that should be measured
under strictly defined experimental conditions. In comparative analyses among mammals …

Several theories have been proposed to explain limits on the maximum rate at which
animals can ingest and expend energy. These limits are likely to be intrinsic to the animal …

The present work is the first in a series of studies aiming at establishing a connection
between the food habits of aves and the anatomical, histological and histochemical …

Most milk replacers (MR) contain more lactose compared with whole milk, which, when fed
at a large meal size, could influence gut barrier function in calves. This study evaluated how …

The causes and consequences of physiological stress in wildlife are of great interest in a
wide range of biological disciplines including understanding how environmental changes …

The assimilation capacity (AC) hypothesis for the evolution of endothermy predicts that the
maternal basal metabolic rate (BMR) should be positively correlated with the capacity for …

Despite the central importance of the rate of energy expenditure in the lives of animals, the
major drivers of within‐species variation in energy expenditure remain uncertain, largely …

One major goal of integrative and comparative biology is to understand and explain the
interaction between the performance and behavior of animals in their natural environment …

Reproduction is an energetically expensive activity for both sexes. However, if males and
females differ in their annual timing of reproduction, such that peak investment for one sex …

For small non-hibernating mammals, a high thermogenic capacity is important to increase
activity levels in the cold. It has been previously reported that lactating females decrease …
