My research focuses on anthropogenic threats to killer whale health and population dynamics. At ÓÐÁϺÐ×ÓÊÓƵ, I will use a multi-decadal sightings and photo-identification dataset to non-invasively assess the impacts of persistent organic pollutants (POPs) upon the health and fitness of mammal-eating ‘Bigg’s’ or ‘Transient’ killer whales in the eastern North Pacific Ocean. As top marine predators, Bigg’s killer whales are extremely vulnerable to bioaccumulation and biomagnification of contaminants; they bear high levels of certain pollutants known to interfere with immune and reproductive function in mammals and are designated ‘Threatened’ under the Canadian Species at Risk Act as a result. My research will enable a better understanding of the long-term effects of accumulated contaminants in these important predators.
