Population cycles of Arctic foxes and lemmings illustrate the strong link between predators and their prey, and dramatically impact many other tundra species. Yet changing snow and ice conditions, and the simultaneous encroachment of southern species onto the tundra, may substantially alter these species interactions.

We will examine these direct and indirect interactions among species at the taiga-tundra transition zone in northern Manitoba, where the impacts of climate change are particularly strong. We will also discuss the hotspots of productivity created by foxes fertilizing den sites, which stimulates plant growth and attracts wildlife.
