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...

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...

Museum of Northern Arizona, Inc. will leverage tools previously developed by the Springs Stewardship Initiative to help resource managers in the southwestern U.S. collect, analyze, report upon, monitor and archive the complex and interrelated information associated with springs and spring-dependent species in the region. The information will be compiled and made readily available online. The Museum will further develop interactive online maps and climate change risk assessment tools of springs-dependent sensitive plant and animal species.

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...
