Dynamic Energy Budget Theory for Metabolic Organisation : Cambridge University Press : 9780521131919 : 052113191X : 15 Oct 2009 : Dynamic Energy Budget (DEB) theory is a formal theory for the uptake and use of substrates (food, nutrients and light) by organisms and their use for maintenance, growth, maturation and propagation. It applies to all organisms (microorganisms, animals and plants).The primary focus is at individual level, from a life cycle perspective, with many implications for sub- and supraindividual levels. The theory is based on sound chemical and physical principles, and is axiomatic in set-up to facilitate testing against data. It includes effects of temperature and chemical compounds; ageing is discussed as an effect of reactive oxygen species, with tight links to energetics. The theory also includes rules for the co-variation of parameter values, better known as body size scaling and quantitative structure- activity relationships. Many well-known empirical models tur
