NWRC studies stressors impacting health of wetlands and aquatic ecosystem. Stressors of concern include hormonally active chemicals (such as synthetic estrogen), microbial pathogens, pharmaceutical compounds, and heavy metals. Fish and birds have proven to be good animal models in which to study the effects.

Dr. Jill Jenkins of NWRC studies the effects of environmental stressors on aquatic organisms such as invertebrates. She collaborates with colleagues from other centers on studies involving biomarkers
