Dr. Louis Guillette was both a professor of obstetrics and gynecology, and a marine biologist. He is famed for studying the effects of chemical pollution on the reproductive systems and behaviours of alligators living in previously polluted Lake Apopka, Florida vs alligators in less tainted areas. He identified these alligators as a sentinel species, and researched the implications they may have for human reproductive biology and behaviours.
