Welcome to DEBwiki, the wiki for all things related to the Dynamic Energy Budget theory.

DEB theory DEB stands for Dynamic Energy Budget. "Dynamic" means that the full life cycle of an individual (micro-organism, plant, or animal) is followed in a changing environment. DEB theory deals with the processes of "Energy" uptake and use, but also with mass, including stoichiometric constraints and isotopes. "Budget" means that balances are respected explicitly. 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.

Add-my-pet Add-my-pet is akin to an online library, but with added features. It contains referenced data, implied properties of species, and DEB parameter estimates and code for obtaining them. Most useful links: The wiki style estimation procedure manual. For getting acquainted with the terminology in the collection, data types, parameter estimation, description of model types etc. Add-my-pet portal. Navigate through the pages of the collection, look at plotted energy budgets and parameter patterns. Learn more about the aims, research, and applications. Meet the people involved, find (or add) your name to the contributors list. AmPtool description. This page describes how to use AmPtool for analysis of data. AmPtool contains Matlab functions for analysis of patterns in (functions of) parameter values of the Add-my-Pet collection. It is an extension of DEBtool_M and makes frequent use of it. AmPeco extension. Listed here you can find coding that is used in the AmP collection to specify climate, ecozone, habitat, embryo environment, migration/torpor, food, gender, and reproduction for each AmP entry. Codes can be used for linking ecological properties to DEB parameters. Scripts are still under development. DEBlab DEBlab is a site that points to material that may be useful for research and education purposes. It aims to facilitate the application of the theory, and to stimulate collaboration. See the original site on DEBlab Here you can find short descriptions and links to packages such as DEBtool, AmPtool, NicheMapR, DEBtox, DEBibm, PlotReader. Data libraries based on DEB: Add_my_pet, Debber, Phyto_pars. Micro-lectures and some course materials, as well as additional learning resources. DEBtool is a software package that can be used to illustrate some implications of the Dynamic Energy Budget theory and to apply this theory in the analysis of eco-physiological data.
