What causes intraspecific variation in resting metabolic rate and what are its ecological consequences? by Burton, T, Killen, S. S, Armstrong, J. D, Metcalfe, N. B

“…Individual differences in the energy cost of self-maintenance (resting metabolic rate, RMR) are substantial and the focus of an emerging research area. These…”

Metabolic rate evolves rapidly and in parallel with the pace of life history by Auer, Sonya K., Dick, Cynthia A., Metcalfe, Neil B., Reznick, David N.

“…Metabolic rates and life history strategies are both thought to set the “pace of life”, but whether they evolve in tandem is not well understood. Here, using a…”
