Abstract
Climate change is directly affecting tundra ecosystems in northern regions, and warming temperatures have caused discontinuous permafrost and thawing sediments across the region. This project investigates how increasing erosion and the foraging patterns of migratory snow geese may degrade habitat for aquatic invertebrates in the upper Mast River, located in Wapusk National Park, Manitoba, Canada. In the past two decades, many of the important species of aquatic invertebrates have shown declines. Declining invertebrate populations are predicted to affect aquatic ecosystems and decrease the resources available to shorebirds and waterfowl, which breed and migrate through this area.
