For animals exhibiting range residency, the home range is a useful framework to quantify
space use. Some reptiles can live decades in the wild and experience extreme …

Imagine one has the rare fortune of watching a cheetah stalking its prey—say an antelope—
and then, instantly, breaking into an “all-out” run, which over a short course brings down the …

Pastoralism is a major agricultural activity in drier environments, and can directly and
indirectly impact native species in those areas. We investigated how the supply of an …

The maximum amount of oxygen consumed during forced exercise (V̇ O2, max) sets the
upper limit to the effort that can be sustained over relatively long periods and can limit …

As water is essential for survival, seasonal scarcity of freshwater resources can pose a
challenge for many species. In xeric environments, efficient location of ephemeral water is …

Lizards dashing rapidly between plants. Songbirds and woodpeckers flying to and from their
nests. Hawks perched on saguaros. What kinds of journeys have these and many other …

Resource subsidies can have profound effects on animal behavior, reproduction, and
growth. Resource subsidies often result from human-altered environments that augment …

Body size can influence nearly every aspect of an organism's biology and ecology, and
drivers of intraspecific variation in ectotherm body size are often poorly understood. We …

The current paradigm in animal organismal biology links morphology, performance,
behavior, and Darwinian fitness in a sequence of proximate causal relations. First, the …

Previous investigations in the field of biological thermoregulation have primarily focused on
small organisms that inhabit ecosystems that are not as strongly seasonal as the tropical dry …
