The Elasmobranch Physiology and Environmental Biology Program conducts basic research on the physiology of reproduction, development, and other essential processes in sharks and their relatives;and applied research on the effects of environmental degradation on these fishes.
|
|
|
Current projects focus on the following topics
Reproductive physiology of viviparous sharks and rays Hormonal regulation of reproduction and development in sharks and rays Exposure and effects of environmental pollutants in freshwater and saltwater elasmobranchs
