Biography:

Robert F. Rockwell is a population biologist and ecologist working primarily on the dynamics of interacting species in the Hudson Bay Lowlands. While the main theme of his 43 year long-term research project has centered on lesser snow geese, work has expanded in the last 20 years to include graminoid primary producers, halophytic plants (representing alternate stable states in degraded habitat), various non-goose herbivores including caribou and predators including arctic foxes, wolves and both grizzly and, especially, polar bears. Current research is focused on the impact of global climate change on the interactions of species in these three trophic levels. He and his colleagues and students integrate field approaches with state-of-the-art analytical and modeling techniques. They are all members of the Hudson Bay Project, an international team dedicated to research in remote, coastal arctic tundra.
