Response to Clarke and Fraser: effects of temperature on metabolic rate

نویسنده

  • J. F. GILLOOLY
چکیده

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 :

influencing all life functions of an organism through changes in the rates of biochemical and physiological processes and in the stability of biomolecules (reviewed by Hochachka and Somero, 1973; Hoffmann, 1983; Prosser, 1991). Adaptation to environmental temperature is recognized as one of the evolutionary mainstreams and is thought to be dependent, to a large extent, on the organism’s ability...

Use of Response Surface Methodology Analysis for Xanthan Biopolymer Production by Xanthomonas campestris: Focus on Agitation Rate, Carbon Source, and Temperature

The current study is an attempt to contribute for efficient and cost-effective substrates for xanthan gum production. In this context, the sugar cane molasses wastes can be used as a cheap substrate for xanthan gum production. Xanthan biopolymer production by a novel Xanthomonas campestris strain IBRC-M 10644 was optimized with statistical approaches. Based on the results ...
