Environmental temperature is projected to rise 2-4˚C in the next 50 years around the world. This will have the most enormous effect on the biology of ectotherms (‘cold-blooded’ animals, and plants). My biological research has often focused on temperature adaptation in ectotherms -from the muscle physiology of Arctic crustaceans (see here) , to reproductive biology in high latitude reptiles (see here). In polar marine environments, sea temperature is already rising notably. My current research in biology is on the effect of ocean warming on development and dispersal in Antarctic fish (see here) .
Impacts of Southern Ocean warming on marine connectivity: Integrating oceanographic modeling with molecular ecology and developmental biology.
This project addresses the question: how might ocean warming affect the connectivity links between populations? Collaborative with the British Antarctic Survey and Bangor University, it integrates thermal biology,oceanographic modeling, molecular ecology and life history evolution. Temperature influences developmental rate, and increased developmental rate can decrease the potential for long distance dispersal for many fish larvae. So how will a 2-4˚C rise in sea temperature in the Antarctic Scotia Sea affect populationconnectivity for species with different life histories?Will important links be lost? Here’s our official site.
