...P. A. Green; M. J. McHenry; S. N. Patek ABSTRACT Measurements of energy use, and its scaling with size, are critical to understanding how organisms accomplish myriad tasks. For example, energy budgets are central to game theory models of assessment during contests and underlie patterns of feeding...
