Post-fire regrowth is an important component of carbon dynamics in Canada's boreal forests, yet observations of structural development following fire are lacking across this remote and expansive region. Here, we used Landsat time-series data (1985–2010) to detect high-severity fires in the Boreal Shield West ecozone of Canada, and assessed post-fire structure for > 600 burned patches (> 13,000 ha) using airborne light detection and ranging (lidar) data acquired in 2010. We stratified burned areas into patches of dense (> 50% canopy cover) and open (20–50% canopy cover) forests based on a classification of pre-fire Landsat imagery, and used these patches to establish a 25-year chronosequence of structural development...

This thesis is about aboriginal and treaty rights to wildlife and wildlife harvesting, including the right to make decisions about these activities in the Northwest Territories. It deals with the erosion of these rights in the period before 1982 and then traces the protection, redefinition and resurgence of these rights since 1982, when section 35 of the Constitution Act, 1982 was enacted. Section 35 affords constitutional protection to treaty and aboriginal rights including those rights negotiated through modern land claim agreements. This thesis shows that the effect of section 35 jurisprudence and land claims has been to halt the erosion of aboriginal and treaty rights to wildlife and to enhance local control...
Although reliable figures are often missing, considerable detrimental changes due to shrinking glaciers are universally expected for water availability in river systems under the influence of ongoing global climate change. We estimate the contribution potential of seasonally delayed glacier melt water to total water availability in large river systems. We find that the seasonally delayed glacier contribution is largest where rivers enter seasonally arid regions and negligible in the lowlands of river basins governed by monsoon climates. By comparing monthly glacier melt contributions with population densities in different altitude bands within each river basin, we demonstrate that strong human dependence on glacier...

Understanding the complexity and ecological organization of protected area ecosystems, and their bioregional surroundings, is fundamental to maintaining their integrity. This research set out to integrate the bodies of systems and hierarchy theory to establish a framework for developing a conceptual model that would synthesize knowledge from diverse fields and identify key system processes, thereby providing new insight into ecosystem organization, function, and integrity. This understanding was then applied to planning for ecological integrity in the Canadian National Parks context through a case study of Kluane National Park and Reserve (KNP&R) within the Greater Kluane Region (GKR). The methodology characterized...
