Varner Professor of Biological Sciences
University of Nebraska-Lincoln
The Janovy lab focused on problems of parasite population and community structure, host specificity, life cycle evolution, and taxonomy. They worked primarily with small fish and invertebrate hosts; the parasites were mainly apicomplexans, particularly septate gregarines. The research group typically included undergraduates as well as graduates; most years there were 2-3 graduate students and 2-4 undergraduates doing research in the lab. The field sites were in western Nebraska, near the Cedar Point Biological Station north of Ogallala, and in southeastern Nebraska in the Salt Valley watershed north and west of Lincoln and in Cass County east of Lincoln.
