Johanna Kraus, PhD
Dr. Johanna M. Kraus is a Research Ecologist at the Columbia Environmental Research Center.
She studies effects of anthropogenic stressors on food webs, biodiversity and environmental health in aquatic and terrestrial ecosystems. She began her career with the USGS in 2011 researching how trace metals from acid rock drainage impact adult aquatic insect emergence and contaminant flux to terrestrial insectivores near mountain streams. Since then, her research has uncovered when and where contaminants may impact aquatic and terrestrial food webs using large empirical field studies, laboratory manipulations and conceptual modelling. Dr. Kraus received her B.A. in Biology from Brown University and Ph.D. in Biology from the University of Virginia.
