Projected rates of climate change over the next century are expected to force species to shift
ranges, adapt or acclimate to evade extinction. Predicting which of these scenarios may be …

Intraspecific variation in avian thermoregulatory responses to heat stress has received little
attention, despite increasing evidence that endothermic animals show considerable …

Summary 1 It has been proposed that habitats with low productivity, and hence low resource
availability, may favour individuals with lower rates of resource use and energy expenditure …

Birds have colonized almost every terrestrial habitat on the planet-from the poles to the
tropics, and from deserts to high mountain tops. Ecological and Environmental Physiology of …

Integration of multiple approaches is key to understand the evolutionary processes of local
adaptation and speciation. Reptiles have successfully colonized desert environments, that …

A large number of physiological acclimation studies assume that flexibility in a certain trait is
both adaptive and functionally important for organisms in their natural environment; …

We used high precision computed tomography (CT) and traditional radiography to study the
nasal conchae, complex structures within the nasal cavity that condition air via …

Avian metabolic responses demonstrate considerable diversity under fluctuating
environmental conditions, a well-studied example being the seasonal upregulation of basal …

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 …

The obligatory cost of living for endotherms is measured by basal metabolic rate (BMR), a
variable that is known to change after thermal acclimation. However, the relative timing …
