Abstract:
The Dynamic Energy Budget (DEB) theory unifies the commonalities between organisms as prescribed by the implications of energetics, which links different
levels of biological organisation (cells, organisms and populations). The theory presents simple mechanistic rules that describe the uptake and use of energy and
nutrients (substrates, food, light) and the consequences for physiological organisation throughout an organism's life cycle, including the relationships of energetics
with aging and effects of toxicants. All living organisms are covered in a single quantitative framework, the predictions of which are tested against a wide variety
of experimental results at the various levels of biological organisation. The theory explains many general observations, such as the body size scaling relationships
of certain physiological traits, and provides a theoretical underpinning to the widely used method of indirect calorimetry.

VI. Additional remarks
The package DEBtool is meant to illustrate the DEB theory, which is described in a book, and in numerous articles (see website for references). This package aims at basic eco-physiology and population dynamics of all organisms (plants, animals, microbes). See package DEBtox for applications in ecotoxicology.
