Environmental Physiology Lab

Welcome to the Environmental Physiology Lab at the University of Guelph led by Dr. Patricia Wright.

We are interested in how animals cope with changes in the environment. We explore the strategies that amphibious fishes use to survive and thrive out of water. We have conducted field work in Belize where the self-fertilizing, amphibious mangrove rivulus (Kryptolebias marmoratus) reside in crab burrows in the forest floor. Learn more at Research.

Research in our lab for many years has been focused on nitrogen metabolism and excretion. Elevated ammonia in the environment is toxic to fish. Recently, we have studied the mechanisms of ammonia transport across fish gills, skin and kidney. We have been interested in the pathways for ammonia excretion. Also, we have examined the pathways for urea transport and excretion. Learn more at Research.

Robyn Simon publishes undergraduate research project on copper toxicity in mangrove rivulus

Robyn’s work, in collaboration with post-doc Tamzin Blewett at the University of Waterloo (now at U Alberta), was published today in Aquatic Toxicology. The short version – copper exposed fish probably improve respiratory ability by increasing gill area, but despite this morphological response the fish are still more sensitive to low oxygen conditions than fish from clean water.

Dr. Wright wins F. E. J. Fry Medal

This medal is awarded from the Canadian Society of Zoologists to those who have made outstanding contributions to knowledge and understanding in the field of zoology.
