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.

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...

Several studies have documented the potential and existing environmental degradation due to all-terrain vehicle (ATV) use in sub-arctic terrain. Impacts include vegetation damage or destruction, changes in vegetation community composition and structure, substrate thermal change and permafrost thaw, and soil erosion and subsequent development of thermokarst features and terrain degradation. One of the most evident effects of prolonged ATV use in sub-arctic tundra is the development of extensive trail braiding. Trail braiding results from alternate trails that are created by users in order to avoid mud bogs and standing water (ponding) that develop on ATV trails which are underlain by ice ridge permafrost. One option...

Analyzes the quantitative framework for breeding and conservation of forest tree genetic resources in British Columbia. Relevance of the methods use in integrating breeding with conservation population Role of in- and ex-situ populations on forest tree gene resource management; Genetic conservation objectives of in situ-populations.

There is a trend towards development of Wrangell-St. Elias National Park to accomodate increased visitor use and to generate additional tourism revenue for the state of Alaska. Master planning should be utilized in setting Park goals, zoning areas for visitor use and wilderness, and ensuring that developments do not erode the conservation values of the Park. Specifically, information on grizzly bears should be incorporated carefully into planning recreational facilities in order to avoid important grizzly bear habitats. Fundamental measures designed to minimize bear-human conflicts should include management of human food and garbage; public education on bears; monitoring of bear data; problem bear control; planning...

Cladonia pyxidata and Cladonia pocillum are commonly referred to as "pixie cup" lichens. The species are mainly delimited by the morphology of the basal squamules, which are upright and separate or form a rosette-like pattern, respectively. Cladonia pyxidata is reported to prefer acidic soils, whereas C. pocillum grows exclusively on basic soils. By examining the morphological and genetic variation of C. pyxidata and C. pocillum , we assess their species status. We also examine whether the variation in morphology correlates with a change in soil pH. Samples from the Cladonia pyxidata group were collected from across Canada. Phylogenetic and population genetic analyses were conducted using 15 morphological characters...
