Dr. Angermeier researches population ecology of imperiled freshwater fish species such as the Roanoke logperch. Additionally, he quantifies and maps the services that healthy aquatic ecosystems provide society, including reliable water supply, water purification, flood modulation, and wildlife-based recreation (fishing and birding).
Dr. Angermeier’s career in fish ecology and conservation has included a wide range of studies in Virginia and other parts of North America. Focal species have included Roanoke logperch, river herring, American eel, variegate darter, northern snakehead, and candy darter. He and his graduate students seek to understand how physicochemical and biological factors regulate fish distribution and abundance, as well as how such knowledge can inform managers of imperiled species and water quality. Recently, he began developing tools to quantify and map aquatic ecosystem services, and the benefits that healthy ecosystems provide society. Focal services include provision of water supply, water purification, flood and drought modulation, and wildlife-based recreation such as fishing and birding. Because these services typically are not represented in markets, reliable measures of their sources and fates can provide valuable information for making societal decisions about how land and water is used.
