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
origin of dermacentor albipictus (acari: ixodidae) on elk in the yukon, canada.winter ticks (dermacentor albipictus) on elk (cervus elaphus canadensis) have recently increased in numbers in the yukon, canada, potentially posing risks to other indigenous host species in the region. to evaluate the regional source of winter ticks in the yukon, we sequenced one nuclear (its-2) and two mitochondrial (16srrna and coi) genes, and genotyped 14 microsatellite loci from 483 winter tick specimens collected across north america. we analyzed genetic variation across the geographic and ...201424779459
brucellosis in moose (alces alces). a serological survey in an open range cattle area of north central british columbia recently infected with bovine brucellosis.a serological survey for brucella abortus antibodies in mature cow moose (alces alces) was made in an area of northcentral british columbia which recently had been heavily infected with bovine brucellosis and in which there was considerable intermixing of moose and range cattle. no evidence of brucella infection was found in the moose tested and it was concluded that they were probably not of great significance in the epidemiology of bovine brucellosis in the study area and were therefore unlike ...19807363258
an analytical platform for cumulative impact assessment based on multiple futures: the impact of petroleum drilling and forest harvesting on moose (alces alces) and marten (martes americana) habitats in northeastern british columbia.the combined influence on the environment of all projects occurring in a single area is evaluated through cumulative impact assessments (cia), which consider the consequences of multiple projects, each insignificant on its own, yet important when evaluated collectively. traditionally, future human activities are included in cia using an analytical platform, commonly based on complex models that supply precise predictions but with reduced accuracy. to compensate for the lack of accuracy in curren ...201121396768
an expanding population of the giant liver fluke (fascioloides magna) in elk (cervus canadensis) and other ungulates in canada.giant liver fluke (fascioloides magna) populations readily expand under suitable conditions. although extirpated from the eastern slopes of the canadian rocky mountains in the early 1960s, the fluke reappeared following natural spread through mountain passes from british columbia. herein, we assessed epizootiology of the fluke population two decades later. between 1984 and 1991, 534 ungulates, including 381 elk (cervus canadensis), 68 mule deer (odocoileus hemionus hemionus), 54 white-tailed dee ...201525647594
