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 process-based 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 or the von Bertallanfy growth curve that a great number of organisms follow. It provides a theoretical underpinning to the modeling biology at the organism level.
This symposium will highlight the fundamental principles underlining DEB theory, examples of how the theory is being applied and may be applied and the educational initiatives taking place.
