Although evolution may guide animals to different sizes, shapes, energetic profiles or ecological niches, it is the laws of physics that limit biological processes and, in turn, affect how animals interact with their environment. Consideration of scaling...

Early experimental work in animal energetics focused on the costs of specific tasks (basal...
