John J. Gilbert

Professor Emeritus of Biological Sciences

I am currently interested in several aspects of rotifer biology and ecology. Specifically, these interests include control of sexual reproduction and diapause in the life cycle, phenotypic plasticity and developmental polymorphisms, and predator-prey interactions.
