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 are exploring how the amphibious, skin-breathing mangrove rivulus (Kryptolebias marmoratus, formerly killifish) are capable of surviving for weeks out of water, either as embryos or adults. We have conducted work in Belize where mangrove rivulus reside in crab burrows in the forest floor. Learn more at Research

We are also fascinated by how the early rearing environment shapes the destiny of physiological responses in later stages of development. Aquatic environments with low oxygen (hypoxia) have a profound impact on the entire hierarchy of orgnaization from genes to whole animals. 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 detoxification in the brain and other tissues. Also, we have examined the pathways for urea transport and excretion. Learn more at Research.

Members of the Wright lab were off to Belize in December. Check out this video of the mangrove rivulus in the field. You can see several fish jumping in and out of a crab burrow and in the last 30 seconds the owner of the burrow shows up for a cameo!
