Biography

My research focuses on Arctic marine mammal space-use, predator-prey dynamics, and fitness under changing seascapes. I am developing models to test the landscape of fear hypothesis, which predicts that predator (polar bear) space-use will indirectly influence prey (ringed seal) space-use, where prey avoid predator distribution on the seascape. I will model the space-use of polar bear and ringed seal, and how the predator-prey relationship is affected by shifts in sea ice regime, and also investigate the temporal effects of a poor-ice-year on the fitness and body condition of ringed seals. In addition to identifying future important areas for important Arctic marine mammals, my research will provide insights on the breadth of impact of a poor-ice year, which is essential for proactive management and conservation.
