Welcome to DEBwiki, the wiki for all things DEB.

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. See also the DEB theory article on Wikipedia.

Upcoming events and courses

If you consider a possible participation in an up-coming DEB course, which is not open yet for registration, for yourself or persons working with you, we suggest that you complete the form for expressing your interest without any obligations; you will receive an email when the registration opens. We will announce the events also on Facebook and Twitter.

Event Location Dates
debX 2020 online 17 Feb-23 Mar 2020 A 5-week course (MOOC) providing a framework for modelling metabolism at the organism level, covering the full life-cycle, using the Dynamic Energy Budget (DEB) Theory. A free online course about DEB theory that has been running for 4 years. This year it will have new French subtitles thanks to the LEMAR group in Brest.
Ecotox (GUTS)focused training courses at SETAC Europe Dublin, Ireland 03-07 May 2020 Learn more about TKTD models, especially GUTS models, and the way to use them through the software and/or web platforms.

A course on the openGUTS software by Tjalling Jager and Roman Ashauer - an afternoon's hands-on course for using the software, so very limited attention to the backgrounds of the GUTS model itself.

TC01 - GUTS Modelling: From the Theory to the Practice (3rd May). A full-day training course organized by Sandrine Charles. Details on the course can be found here. (Practical: R software and MOSAIC web platform)

Summer school "Dynamic modelling of toxic effects" Denmark 10-19 Aug 2020 Registration is open, and will close on 31 May 2020 (or when we reach the maximum number of participants). More information on the course page. Download flyer.
DEB 2021 tele-course, School & Symposium ?? Canada spring 2021 Tentative location for the DEB2021 edition is Canada. More information will be added closer to the event.

Rejoignez-nous dans cette première version en français.

would you be willing to put the info on the DEB MOOC that starts on the 17th as well as check out Tjalling websites and put the info on their DEBtox course in the upcoming events? See here for all events


DEBnet

DEBnet is a network of DEB experts in a wide range of fields: Aquaculture, Mathematics, Ecotoxicology, Economics, Ecology ...

Publications

DEB literature and publications span from:
  • introductory material in form of posters and micro-lectures;
  • complete DEB immersion via book (DEB3) with accompanying summary of concepts, notation document, and frequently updated Comments; to
  • scientific publications using or focusing on DEB theory, collected in the Zotero DEB library.
  • Several (scientific) journal special issues have been dedicated to DEB theory.

For a full list of resources and special issues see here.

Communication and outreach

Other on-line places to find DEB: AmP on ResearchGate,AmP on Facebook, AmP on Twitter.

Subscribe to the DEB mailing list here: deblist@univ-brest.fr (allows you to receive and send scientific information and job offers within the DEB community)


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:

  • 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 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.
