Climate Change, Trophic Cascades, and Apex Predators in Greenland
The mechanisms by which variability in sea ice cover, oceanography, and primary production cascade to other ecosystem components such as top predators remain poorly understood. Yet these interactions are essential for understanding the links between climate change, biophysical responses in the ecosystem, and resource monitoring and management in the Arctic. This talk will focus on physical forcing and trophic interactions between marine mammals and sea birds in West Greenland and discuss how top predators can be used to understand and monitor polar ecosystems.
Kristin Laidre’s research is focused on how climate-based ecosystem changes impact Arctic top predator life history and behavior at various spatial and temporal scales. She received her Ph.D. from the School of Aquatic and Fishery Sciences at the University of Washington in 2003 and completed a 2-year post-doc in Denmark and Greenland funded by the National Science Foundation’s International Research Fellowship Program. Kristin joined the Polar Science Center, Applied Physics Lab, UW in fall 2006 and continues research on spatial modeling of movement and spatially-explicit foraging ecology of top marine predators in the Arctic.
