Steve Perry

Dr. Perry has four ongoing research projects that are unified by a common theme; the adaptation of fish to stressful or extreme environments.

1. The role of stress hormones in controlling cardio respiratory function and blood gas transport in fish during environmental disturbances.
2. The physiological and molecular nature of gill and renal transepithelial ion movements and their modulation during environmental and acid-base disturbances.
3. The molecular basis of hypoxic pre-conditioning in zebra fish and the ontogenetic effects of chronic environmental disturbances on cardio respiratory function.
4. The nature of oxygen and carbon dioxide sensing by chemoreceptors and its linkage to cardio respiratory control.
