Steven Mamet, a postdoctoral fellow in the Department of Biology at the University of Saskatchewan, completed his B.Sc. and his M.Sc. and Ph.D. in earth and atmospheric sciences under Dr. Peter Kershaw at the University of Alberta. He joined the Northern Plant Ecology Lab in August 2012. His graduate research focused on range limits of tree species at northern tree lines, and how climate and environmental change shape tree line dynamics. In his current research, he is evaluating range limits at tree line near Wolf Creek, Yukon Territory, and assessing climate variation and forest resilience along moisture gradients in central Saskatchewan.
