Research: Celia Chen studies the way food web structure and trophic status affect the transfer of metals and other contaminants from lake water and diet to fish. Her research involves investigating metal levels in phytoplankton, zooplankton and fish in a broad gradient of lakes located in pristine, urban and Superfund watersheds. She also examines the relationships between environmental and land use characteristics on metal concentrations in lakes. She is also studying stress proteins in zooplankton as field biomarkers of metal exposure, the potential for hybridization in sympatric zooplankton populations, the consequences of climate change for aquatic communities and multiple stressor effects of herbicides, pH and food deprivation on wetland populations of zooplankton and tadpoles.
