In two recent papers, Clarke and Fraser (2004) and Clarke (2004) discussed the empirical data and the mechanistic processes relating metabolic rate to temperature. They criticized the framework proposed recently by Gillooly et al . (2001) and presented an alternative evolutionary trade-off hypothesis. Gillooly et al . (2001) (see also West, Brown and Enquist 1997; Gillooly et al . 2002; Charnov and Gillooly 2003; Brown et al . 2004a,b) developed a theory for the scaling of metabolic rate that combines the effects of two primary variables, body size and temperature, based on first principles of physics, chemistry and biology – including the fitnessmaximizing dynamic of natural selection. This leads to a single equation for whole-organism metabolic rate, B :
