Effects of Simultaneous Multiple Perturbations on Aquatic Food Webs

EPA Grant Number: U915210
Title: Effects of Simultaneous Multiple Perturbations on Aquatic Food Webs
Investigators: Klug, Jennifer L.
Institution: University of Wisconsin - Madison
EPA Project Officer: Smith, Bernice
Project Period: December 1, 1997 through December 1, 2000
Project Amount: $84,201
RFA: STAR Graduate Fellowships (1997)
Research Category: Academic Fellowships , Ecological Indicators/Assessment/Restoration , Fellowship - Ecology and Ecosystems



The objectives of this research project are to: (1) determine whether the effects of simultaneous multiple perturbations are predictable, given the knowledge of the effects of individual perturbations; and to(2) determine whether there are interactions among perturbations.


I am using a combination of experimental and modelling approaches to investigate the combined effects of increased nutrients and dissolved humic organic matter on phytoplankton communities.
