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...
Wrangell-St. Elias National Park and Preserve is experiencing rapid, but controlled development in connection with its 1998 purchase of the Kennicott Mill Site in the McCarthy-Kennicott area. As development and increased tourism/visitation occurs in this largely rural area, the potential for increased conflicts between bears and humans occurs. Research was initiated in 2000 to study specific elements of the "conflicts" and how best to mitigate and/or eliminate the problems.
Background Elucidating geographic locations from where migratory birds are recruited into adult breeding populations is a fundamental but largely elusive goal in conservation biology. This is especially true for species that breed in remote northern areas where field-based demographic assessments are logistically challenging. Methodology/Findings Here we used hydrogen isotopes (δD) to determine natal origins of migrating hatch-year lesser scaup (Aythya affinis) harvested by hunters in the United States from all North American flyways during the hunting seasons of 1999-2000 (n = 412) and 2000-2001 (n = 455). We combined geospatial, observational, and analytical data sources, including known scaup breeding range,...

Free-ranging ungulates in North America are host to over 50 species of parasitic gastrointestinal nematodes (strongyles), many of which vary in their pathogenicity and response to anthropogenic and climatological disturbance. Consequently, species-specific identification is crucial to understanding the epizootiology of strongyles in wildlife. I validated a molecular assay (PCR-SSCP) for species-level differentiation of strongyles, and used this approach to help describe strongyle communities in western Canadian cervids. Three new host and ten new geographic records were described. Deer ( Odocoileus spp.) harboured a high diversity of strongyles with a distinct geographic partitioning of species. Prevalence of infection...

The Environmental Directorate of DIAND in Whitehorse sponsored a workshop in Whitehorse during two-days in November, 2000. The purpose of the workshop was to identify and refine wildlife thresholds for cumulative effects in the Yukon, and identify means of implementing those thresholds. The workshop was attended by 30 participants, mostly federal and territorial government, and was facilitated by AXYS Environmental Consulting Ltd. This workshop is part of a four-phased approach to implementing thresholds. The first phase involves the completion of a background report on types of thresholds. The second phase, of which this workshop is a part, develops and refines the thresholds for practical application in the Yukon...
