locations of moose in northwestern canada with hair loss probably caused by the winter tick, dermacentor albipictus (acari: ixodidae).five hundred two trappers representing 389 registered traplines in northern alberta, northern british columbia, northwest territories and yukon territory (canada) responded to a questionnaire on the occurrence of hair loss and the winter tick (dermacentor albipictus) on moose (alces alces). results suggested that winter ticks may occur as far as 62 degrees n. several sightings of moose with presumed tick-induced hair loss near kluane lake, yukon territory, suggest the possibility of introduction ...19892761020
investigation, control and epizootiology of anthrax in a geographically isolated, free-roaming bison population in northern july 1993 anthrax caused significant mortality in an isolated, free-ranging population of bison (bos bison athabascae) west of great slave lake in the northwest territories. there was no previous record of anthrax in this area. an emergency response was undertaken to reduce the scale of environmental contamination and dissemination of anthrax spores and hence to reduce the likelihood of future outbreaks. one-hundred-and-seventy-two bison, 3 moose (alces alces), and 3 black bear (ursus america ...19958548686
risk assessment of cadmium exposure in fort resolution, northwest territories, canada.the aim of this study is to investigate the cadmium (cd) exposure level from traditional food in fort resolution, northwest territories. we used 24-h dietary recalls and traditional food use frequency to obtain information on traditional food consumption, and analysed cadmium concentrations in traditional food. we also estimated total cadmium intake via market and traditional food, and cigarette smoking. traditional food accounted for only 10% of the dietary energy. about 30 species of wildlife ...19989666890
spatial and temporal trends of contaminants in terrestrial biota from the canadian arctic.contaminants in the canadian arctic have been studied over the last twelve years under the guidance of the northern contaminants program. this paper summarizes results from that program from 1998 to 2003 with respect to terrestrial animals in the canadian arctic. the arctic terrestrial environment has few significant contaminant issues, particularly when compared with freshwater and marine environments. both current and historical industrial activities in the north may have a continuing effect o ...200516109438
fostering community-based wildlife health monitoring and research in the canadian north.many northern canadians have continued a subsistence lifestyle of wildlife harvesting and, therefore, value sustainable wildlife populations. at a regional wildlife workshop in the sahtu settlement area, northwest territories in 2002, elders and community leaders raised concerns regarding wildlife health, food safety, and the effects of climate change on wildlife. they requested that efforts be put toward training youth in science and increasing involvement of hunters and youth in wildlife resea ...200919953294
caribou consumption in northern canadian communities.chronic wasting disease (cwd) is a transmissible spongiform encephalopathy (tse) found in both farmed and wild deer, elk, and moose in the united states and canada. surveillance efforts in north america identified the geographical distribution of the disease and mechanisms underlying distribution, although the possibility of transmission to other cervids, including caribou, and noncervids, including humans, is not well understood. because of the documented importance of caribou (rangifer tarandu ...201627556568
cadmium and other elements in tissues from four ungulate species from the mackenzie mountain region of the northwest territories, canada.tissue samples from four ungulate species from the south mackenzie mountain region of the northwest territories (nt), canada, were analysed for stable and radioactive elements and (15)n and (13)c stable isotopes. elevated cd concentrations in moose (alces americanus) kidney have been observed in the region and are a health care concern for consumers of traditional foods. this study examined the factors associated with, and potential renal effects from, the accumulation of cadmium, and interactio ...201627240258
