Divergent evolution of colony-level metabolic scaling in ants. [PDF]

open access: yesJ Anim Ecol
The study shows for the first time that the metabolic scaling of active ant colonies varies as a function of trophic level and worker polymorphism. Therefore, the ecological divergence of metabolic scaling observed in unitary organisms occurs across levels of biological organization.
