The Effects of Endocrine Disruption on the Sexual Differentiation of the Amphibian Brain
broad research interests include the effects of endocrine disrupting chemicals
on the reproductive morphology and physiology of developing vertebrates.
Specifically, she will be studying the effects of the widely-used herbicide,
atrazine, on the sexual differentiation of the brain and gonads of two
species of toad found in South Florida: the Oak Toad, Bufo quercicus,
and the Cane Toad, Bufo marinus. Previous studies have yielded controversial
results regarding the feminizing capabilities of atrazine, especially
at environmentally relavent concentrations, on the testes of developing
frog tadpoles. Lisa’s study will test the effects of atrazine on
the reproductive tissue of developing toads. She will be looking at the
possible consequences of atrazine exposure on the gonads as well as the
brain. Her study will especially focus on the possible effects of atrazine
on the portions of the brain that govern mating and reproduction. She
will employ basic histological and immunocytochemical techniques as well
as light and confocal microscopy for her project.
