At nearly 70 tonnes, the subjects of Dr. Timothy Frasier's research are massive examples of how quickly a species can progress to the brink of extinction. North Atlantic right whales are one of the most endangered large whales globally, with fewer than 400 in existence. While protection initiatives are in place, Dr. Frasier is concerned with the whale's low reproduction rate.
Using genomic data, Dr. Frasier works to better understand what genetic factors limit the species' recovery. Early hypotheses suggest that low genetic variation and inbreeding could be possible factors. By determining the factors that limit reproductive success, conservation efforts can be more effective and efficient in saving the species from extinction.

"By working with colleagues and governments in Canada and the United States, we can move fairly quickly from research results to impacts on policy and procedures," says Dr. Timothy Frasier of the Faculty of Science. "Right whales are in a very precarious situation, and we need to identify how conservation actions can be changed to improve the chances for the species to recover."
With $6 million in new funding, Dr. Frasier and his colleagues from Genome Atlantic and the New England Aquarium can continue their research into what factors limit the reproductive success of right whales. This work will help focus conservation efforts to save these beautiful mammals.
