A WORKSHOP ON MULTIVARIATE STATISTICAL ANALYSIS IN ECOTOXICOLOGY
Saturday, 16 November 1996, 8:30 - 5:30, Washington Hilton and Towers
Presented in conjunction with the SETAC 17th Annual Meeting,
Frameworks for ecological risk assessment often culminate in the
evaluation of effects under simulated or actual environmental conditions.
A fundamental objective of such semi-field and field studies is to investigate
effects at the community and ecosystem level. To this end, data are collected on
a large number of ecological variables, including manipulative experiments (artificial
streams, mesocosms, terrestrial field trials), environmental monitoring (before/after,
upstream/downstream), and ecological surveys (plants, bird census).
Data from these studies are usually evaluated by using univariate
statistics (e.g. analysis of variance, concentration-response regression). These have
limitations because it is only possible to look at a limited number of variables
within the ecosystem at any one time, limiting effects determination to the
population level, whereas the objective is normally to understand effects at higher
levels of organization.
The advent of greater computing power and recent developments of new
multivariate statistical tools has made available a variety of techniques (e.g.
CANOCO, RIFFLE, PRIMER) with the potential to overcome some of these previous
limitations. Consequently, there is growing interest among ecotoxicologists in
applying such techniques to field studies in order to be able to generate true
community and ecosystem endpoints. This workshop will provide an excellent
opportunity for interested individuals to meet and exchange views on these approaches
and allow developers of the statistical approaches to discuss the development and
application of the techniques.
The objective of this workshop is to provide information on and generate discussion
of multivariate statistical techniques in ecotoxicological field studies, focusing on the
application of techniques for generating community and ecosystem level statistics,
rather than mathematical derivation.
Attendance will be limited to 100 people to maximize information
Registration is first-come, first served. The registration fee is
$255, and forms can be obtained from the SETAC Office.
Workshop proceedings will be provided to all registrants at no
additional cost, and will be available for purchase by others after the workshop.
