Event Details

Stephen Bowen will give a presentation on sea lamprey ecology focusing on the interesting feature of varying growth rates of the larvae from stream to stream and how crowding reduces their growth rate. Thus, it is curious that larvae do not spread out in streams but rather congregate in specific habitats thereby greatly increasing crowding. Is food quality the critical factor?  What determines food quality – nutrient content or digestibility or both?  What possible effect could crowding have on food quality.  In this presentation, each of these questions will be answered and an integrated life history strategy for larval lampreys will be proposed. 

Stephen Bowen, Ph.D., is the William R. Kenan, Jr. Professor of Biology Emeritus, and Dean Emeritus of Oxford College of Emory University.  He previously served as a Senior Fellow of the Association of American Colleges and Universities, Provost and Vice President for Academic Affairs at Bucknell University, and Professor, Department Head, Associate Dean, and interim Provost at Michigan Technological University.  His research has focused on the population dynamics and feeding ecology of fishes with an emphasis on those fish species that feed on biofilm.  His findings have been reported in 41 scientific papers in such journals as Science, Nature, Ecology, and Limnology and Oceanography.  He and his wife currently live in Grand Haven, Michigan.
