Overview

Being retired, I mostly advise graduate students these days. I have been involved, with students and colleagues, in numerous studies using the mosquitofish (Gambusia affinis) as a model organism for evaluating the effects of endocrine-disrupting chemicals. I have collaborated with Drs. McClintock and Amsler and graduate students on the effects of lowered seawater pH, due to elevated levels of atmospheric CO2, on the fitness of antarctic invertebrates that make calcareous shells.

I have also worked with Dr. Marion and several graduate students to study the effects of urban development in a watershed on aquatic habitat quality and biological diversity in rivers. These studies employed EPA-recommended methods to assess the quality of the aquatic habitat and biological diversity (fish and macroinvertebrates) at numerous sites on rivers in the Birmingham vicinity.
