Antarctic fish: Cold water specialists or adaptable generalists?
The aim of the project is to examine the ability of Antarctic notothenioid fish to acclimate to elevated temperatures. It will focus on one aspect of the physiology of fish, that of oxygen uptake and its use by the tissues of the body. Using a variety of techniques from whole animal physiology down to looking at the activities of individual molecules, this work will determine how important respiration is to the metabolic changes needed for successful acclimation.
