See also the very nice Viewpoint write up in the same issue of BioScience by Colleen T. Webb. She places this paper into context. She states that our paper is "an important synthesis from two hitherto largely separate fields of biological inquiry. One is the conceptually well-established, although not uncontentious, area of allometric scaling laws. The other is the less-established area known as resilience concepts in ecology."
