Research Interests

Winter mortality of alewives is one of the key destabilizing forces in the interactions between piscivores and alewife in the Great Lakes, and the basic question of why Great Lakes alewives survive some winters and die in others has never been satisfactorily explained. My research examines physiological factors associated with winter mortality of alewives and other Great Lakes fishes, especially the influence of dietary lipids and fatty acids on lower lethal temperatures. Analytical techniques used in my laboratory include extraction and purification of lipids from fish tissues, and fatty acid analysis using gas chromatography.
