DEBtox information


Welcome to the DEBtox information site

Welcome to the DEBtox information page, the site for people that want to make sense of ecotoxicity data. This site contains information on mechanistic models for the analysis of stressor effects on the life-history traits of individual organisms (and from there to higher and lower levels of biological organisation). Specifically, this site is about models based on animal energy budgets (DEBtox and DEBkiss) and survival models from the GUTS framework.

This website constitues a node in the international DEBnet network, together with the associated site of DEBtox Research.

The mission of  is to simplify biology to get to the essence of what toxicants (and other stresses) are actually doing to organisms. Simplification is necessary if we need to gain understanding. Furthermore, we cannot expect to test even a small fraction of all possible (combinations of) toxicants, species and environmental conditions. Once we get to the essence, it is possible to make educated predictions of toxicant effects for untested chemicals, untested species, and under untested conditions.

Here, you can find information, lists of relevant publications, (links to) free e-books, and freely downloadable Matlab packages to analyse your data. Use the major categories on the top left of the screen to navigate through this site; the corresponding sub-categories will appear right next to it in the submenu.

Upcoming courses and events

  • In the first part of 2017, there will another round of the international DEB course, with a tele part (March-April at your own location) and a hands-on part (in Tromsø, Norway, 21-30 May). More information.
  • 31 May-2 June. Immediately after the DEB course, there will be the 5th International DEB Symposium, also in Tromsø (call for abstracts has opened). More information.

Job opportunities

  • The University of York has a PhD position on TKTD modelling in small, terrestrial, mammals. The project will be supervised by Dr. Roman Ashauer. More information. Note: applicants must be a UK or EU candidate who has resided in the UK for at least 3 years.
