David Hik
David Hik is Associate Professor of
Biological Sciences at the University of Alberta. His interests have
included the effects of lesser snow geese on salt marshes along Hudson
Bay, the effects of predators on the 10-year cycle of the snowshoe hare,
and the restoration of Australian woodlands. For the past decade, his
research has focused on plant-herbivore-climate interactions in northern
alpine ecosystems. The mountains of the southwest Yukon are currently an
epicenter of climate warming and offer exceptional opportunities to
investigate the physical and biological sensitivity to climate change in
alpine ecosystems. Plant communities, forage species, and mammalian
herbivores, including Dall sheep, collared pikas, hoary marmots and Arctic
ground squirrels, all appear to be sensitive to climate variability. Using
a multidisciplinary approach, it has been possible to begin to untangle
the processes which influence the dynamics of species living in these
northern mountains.
