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 constitutes a node in the international DEBnet
network, together with the associated site of DEBtox Research.
The mission of DEBtox.info is to simplify biology to
get to the essence of what toxicants (and other stresses)
are 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 sub-menu.
Messages and warnings
The free and open-source software openGUTS v1.1 is
now available for download!
It is available as a standalone Windows executable
or as Matlab package. It supports the use of GUTS for regulatory
purposes, but will also prove useful for scientific
studies. The dedicated website http://openguts.info/
provides more information. Version 1.1 repairs a
calculation error that was spotted in
openGUTS, which may affect IT
calibrations/predictions for specific types
of exposure scenarios. The Matlab version
has also been updated to v1.1 to repair
this. For more information, see the openGUTS
For users of BYOM
versions before v. 4.3, see the notes and warnings
on the BYOM page (bottom of
page). But, really,
you should update to a newer version ... If you are
working with BYOM, and would like to be notified
immediately in case of errors, new versions, etc., email me and I will
include you in a mailing list. I may also use this
mailing list for other important developments such
as new (versions) of the e-books, and new papers.
This saves you the hassle of checking this website
every week ;-).
