The allometry of daily energy expenditure in hummingbirds: an energy budget approach

Anusha Shankar, Donald R Powers, Liliana M Dávalos & Catherine H Graham
1. Within-clade allometric relationships represent standard laws of scaling between energy and size, and their outliers provide new avenues for physiological and ecological research. According to the metabolic level boundaries hypothesis, metabolic rates as a function of mass are expected to scale closer to 0.67 when driven by surface-related processes (e.g., heat or water flux), while volume-related processes (e.g., activity) generate slopes closer to one. 2. In birds, daily energy expenditure (DEE) scales with body...
