Energy scarcity is a central driver of animal behavior and evolution. The amazing diversity of life on this planet is a testament to the plethora of novel biological solutions to the problem of ...

Competitive swimmers know that swimming underwater causes less drag resistance than swimming at the surface. Splashing around making waves isn't the most efficient way to swim. Any energy spent ...

Researchers questioned if coordinated group movements by animals moving through a fluid could reduce the energy cost of locomotion. By combining biomechanics and bioenergetics the researchers found ...

Pairing video with simple, lab-based oxygen measurements vastly expands the study of movement energy in ecology, physiology, and beyond Energy scarcity is a central driver of animal behavior and ...

Strong methods do exist for measuring animal movement in the context of energy expenditure, but these are limited by the physical size of the equipment used. Now, in a paper published in the Journal ...
