A Biogeoscience Approach to Ecosystems

Edward A. Johnson is Professor of Ecology and Director of the Biogeosciences Institute at the University of Calgary. He has published extensively on the couplings between physical and ecological systems, with a particular focus on the effects of wildfires, hillslope and fluvial geomorphic processes, climate and land use on tree populations. Yvonne E. Martin is Associate Professor in Geography and Associate Director of the Biogeosciences Institute at the University of Calgary. Her research focuses on drainage-basin geomorphology and its interconnections with ecology, climatology and hydrology.
