Webinar 38 | Climate change and mercury interactions in Arctic marine mammals

Presenter: Jean-Pierre Desforges; PDF, McGill

Summary: Climate change and mercury are two of the greatest threats to Arctic marine predators like narwhals and beluga. Not only do these stressors exert individual impacts, but they also interact to cause often unpredictable consequences. Long-term datasets and access to relevant biological tissues and associated biomarkers are rare in Arctic species and thus hinder our understanding of stressor effects. In this webinar I will discuss the use of narwhal tusk and beluga teeth as unique and valuable archives of historical data on mercury and climate change.
