PRIMENet research projects are designed to investigate the effects of environmental stressors on natural ecosystems. These projects will be funded in 1999 and 2000, and results are expected in early 2001. Six of the projects were chosen by a competitive RFA process and the other projects include "in-kind" projects by EPA investigators (B. McKane and E. Heithmar) and a series of amphibian projects funded by PRIMENet.
