Metabolism provides a basis for using first principles of physics, chemistry, and biology to
link the biology of individual organisms to the ecology of populations, communities, and …

The physiological responses of organisms to resources and environmental conditions are
important determinants of niche boundaries. In previous work, functional relationships …

FIG. 1.(A) Predictive power of body size. We used the data in Brown et al.(2004) and
simulations relationship between the range of organism sizes studied and the explanatory …

Metabolism sustains life and controls the growth, reproduction, and longevity of living
entities. As Brown et al.(2003, 2004) show, the" fire of life" is central to our understanding of …

We re-analyze the assumptions underlying two recently proposed ontogenetic growth
models [Nature 413 (2001) 628; Nature 417 (2002) 70] to find that the basic relations in …

We welcome the opportunity to respond to the com-mentaries in this Special Feature. We
are well aware that this is not the last word. A full evaluation of the metabolic theory of …

James Brown and his colleagues (2004) are at the forefront of a recent resurgence of
interest in explaining the ubiquitous relationships between the body size of organisms and …

MTE also will surely fail if pushed too far. The un-explained variances in the figures in Brown
et al.(2004) are undoubtedly just a preview of what will arise as the theory attempts to widen …

Metabolism, and thus population dynamics, can be limited by energy, carbon, nitrogen,
and/or other nutrients. This is due to homeostasis, the relatively constant composition of …

Dynamic energy budget models relate phenomena at many levels of ecological organization
and can provide quantitative links from individual physiology to population, community, and …
