  • Assistant Professor in Vertebrate Ecology
FORS Room 211
195 Marsteller Street
West Lafayette, IN 47607-2033

Dr. Hoverman’s research program focuses on environmental stressors in aquatic ecosystems.  While the definition of ‘environmental stress’ varies considerably across disciplines and among researchers, it is clear that organisms must cope with natural (e.g., predators, pathogens, competitors) and anthropogenic (e.g., chemical contaminants, habitat loss) factors that exhibit spatiotemporal variation.  Dr. Hoverman’s research seeks to understand the separate and combined effects of natural and anthropogenic stressors at multiple scales of ecological organization (i.e. individuals to ecosystems).  To address his research interests, he utilizes freshwater aquatic systems (e.g., ponds, wetlands, and lakes) and their associated taxa (e.g., tadpoles, snails, insects, fish, parasites).  Within the framework of environmental stressors, he integrates research on predator-prey interactions, ecotoxicology, and disease ecology.  For more information about Dr. Hoverman’s research, visit his personal website.
