Studies moose or Alces alces, caribou or Rangifer tarandus and grizzly bear or Ursus arctos distribution in relation to road traffic in Denali National Park, Alaska. Development of wildlife monitoring system using 19 landscape level viewsheds stratified into four sections based on decreasing traffic along the road corridor; Absence of traffic avoidance patterns for caribou and grizzly bears.

We used the Muskwa-Kechika Management Area in northeast British Columbia, Canada as a case study to determine potential conflicts between future resource development and high-value habitats of large mammals in an undeveloped boreal landscape. More than 50 % of high-value habitats for caribou, moose, elk, wolves and grizzly bears were located in Special Resource Management Zones, where natural resource developments could occur. We developed geographic information system (GIS) layers of potential forest resources, oil and gas, minerals, wind power, all resources combined, and roads; and quantified the proportions of high-value habitats overlapping these potentials. Greater proportions of high-value habitats across...

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...

The northern treeline is generally limited by available warmth. However, in recent years, more and more studies have identified drought stress as an additional limiting factor for tree growth in northern boreal forests and at treelines. Three growth responses to warming have been identified: increase in growth, decrease in growth, and nonsignificant correlation of tree growth with climate. Here we investigate the effect of drought stress on radial growth of white spruce at northern treelines along a longitudinal gradient spanning the entire Brooks Range in Alaska. We systematically sampled 687 white spruce at seven treeline sites. Where possible, we sampled three site types at a given site: high-density forest,...

Originating from different activities that were part of the University of Alaska’s contribution to the Fourth International Polar Year, this interdisciplinary volume addresses a host of current concerns regarding the rapid transformation of the Arctic and its impacts on people and ecosystems. Close to a hundred contributors with a broad range of backgrounds examine Arctic change from an Alaska perspective, providing insight into different approaches of evaluating and preparing for environmental and socio-economic change. Thanks to its coverage of important social-ecological systems and processes, including fresh water, marine resources, the coasts, and oil and gas development, this volume explores opportunities...
