Tracing how free-ranging organisms interact with their environment to maintain water
balance is a difficult topic to study for logistical and methodological reasons. We use a novel …

Recent experiments on shorebirds have demonstrated that maintaining an active
osmoregulatory machinery is energetically expensive. This may, in part, explain diet and …

Endotherms dissipate heat to the environment to maintain a stable body temperature at high
ambient temperatures, which requires them to maintain a balance between heat dissipation …

Predictions indicate that birds worldwide will be affected by global warming and extreme
climatic events which is especially relevant for passerines because the diurnal habits, small …

Understanding physiological traits and ecological conditions that influence a species
reliance on metabolic water is critical to creating accurate physiological models that can …

Sublethal dehydration can cause negative physiological effects, but recent studies
investigating the sub-lethal effects of dehydration on innate immune performance in reptiles …

The field metabolic rate (FMR) of an endothermic animal represents its energy expenditure
in a natural environment, or its energy budget, and its field water flux (FWF) reflects the …

We compared geographic trends in body mass in a number of populations of the olivaceous
field mouse (Abrothrix olivaceus,) along a latitudinal gradient in Chile, and tested the …

The climatic variability hypothesis (CVH) states that species are geographically more
widespread at higher latitudes because individuals have a broader range of physiological …

One of the most controversial hypotheses that associate basal metabolic rate (BMR) with
food habits and habitat productivity is the food habit hypothesis (FHH). Here we examined …
