| radiographic examination of mandibular lesions in barren-ground caribou. | dental anomalies were observed in 43 of 1,226 barren-ground caribou (rangifer tarandus groenlandicus) taken between 1966 and 1968. in five of these 43 animals, the mandibles had deformities which radiography showed to be the result of dental abscesses in four cases and probably of a trauma in the other. the absence of actinomycotic lesions of the jaw bones of these 1,226 animals, and of more than 500 examined previously, indicates that "lumpy jaw" is rare in barren-ground caribou. the authors su ... | 1975 | 519 |
| brucella suis biotype 4: a case of granulomatous nephritis in a barren ground caribou (rangifer tarandus groenlandicus l.) with a review of the distribution of rangiferine brucellosis in canada. | severe granulomatous nephritis caused by brucella suis biotype 4 was found in a barren ground caribou (rangifer tarandus groenlandicus) from northwest territories, canada. a review of the distribution of human and animal cases of brucellosis in northern canada indicated that b. suis biotype 4 is distributed widely and is probably enzootic in most canadian caribou herds. | 1986 | 2902236 |

| radionuclides in the lichen-caribou-human food chain near uranium mining operations in northern saskatchewan, canada. | the richest uranium ore bodies ever discovered (cigar lake and mcarthur river) are presently under development in northeastern saskatchewan. this subarctic region is also home to several operating uranium mines and aboriginal communities, partly dependent upon caribou for subsistence. because of concerns over mining impacts and the efficient transfer of airborne radionuclides through the lichen-caribou-human food chain, radionuclides were analyzed in tissues from 18 barren-ground caribou (rangif ... | 1999 | 10378999 |
| prevalence of toxoplasma gondii antibodies in barren-ground caribou (rangifer tarandus groenlandicus) from the canadian arctic. | prevalence of antibodies to toxoplasma gondii was determined in 147 barren-ground caribou (rangifer tarandus groenlandicus) from 5 herds in the northwest territories and nunavut, northern canada, by the modified agglutination test (mat). in the mainland herds (bluenose, bathurst, and beverly), antibodies were found in 43 (37%) of 117 caribou, and mat titers were 1:25 in 10, 1:50 in 24, and 1:500 in 9. in the island herds, only 1 (4.3%) of 23 animals sampled from the north baffin island herd was ... | 2001 | 11318582 |
| mitochondrial dna and microsatellite dna variation in domestic reindeer (rangifer tarandus tarandus) and relationships with wild caribou (rangifer tarandus granti, rangifer tarandus groenlandicus, and rangifer tarandus caribou). | reindeer (rangifer tarandus tarandus) in alaska are semidomestic livestock descended from 1280 animals introduced from siberia, russia, approximately 100 years ago. genetic variation at 18 microsatellite dna loci and the cytochrome b gene of mitochondrial dna (mtdna) was quantified in reindeer from alaska, siberia (russia), and scandinavia and compared with wild north american caribou. mean sequence divergence among 15 mtdna haplotypes in reindeer was 0.007 substitutions per nucleotide site, and ... | 2006 | 16837563 |
| survival in the rockies of an endangered hybrid swarm from diverged caribou (rangifer tarandus) lineages. | in north america, caribou (rangifer tarandus) experienced diversification in separate refugia before the last glacial maximum. geographical isolation produced the barren-ground caribou (rangifer tarandus groenlandicus) with its distinctive migratory habits, and the woodland caribou (rangifer tarandus caribou), which has sedentary behaviour and is now in danger of extinction. herein we report on the phylogenetics, population structure, and migratory habits of caribou in the canadian rockies, util ... | 2009 | 19175508 |
| filter-paper blood samples for elisa detection of brucella antibodies in caribou. | we evaluated blood collected on nobuto filter-paper (fp) strips for use in detecting brucella spp. antibodies in caribou. whole blood (for serum) and blood-saturated fp strips were obtained from 185 killed arctic caribou (rangifer tarandus groenlandicus). sample pairs (serum and fp eluates) were simultaneously tested in duplicate using competitive enzyme-linked immunosorbent assay (c-elisa) and indirect elisa (i-elisa) for brucella spp. prior work based on isolation of brucella spp. revealed sen ... | 2011 | 21269992 |
| discovery and description of the "davtiani" morphotype for teladorsagia boreoarcticus (trichostrongyloidea: ostertagiinae) abomasal parasites in muskoxen, ovibos moschatus and caribou, rangifer tarandus from the north american arctic: implications for parasite faunal diversity. | abstract collections to explore helminth diversity among free-ranging ungulates in the north american arctic revealed the occurrence of a third male, or "davtiani," morphotype for teladorsagia boreoarcticus. designated as t. boreoarcticus forma (f.) minor b, the males occurred with t. boreoarcticus f. major and t. borearcticus f. minor a in endemic populations of muskoxen (o. m. wardi) and barrenground caribou (r. tarandus groenlandicus) on victoria island, nunavut, canada and in muskoxen an ... | 2011 | 21942428 |
| Subpopulation structure of caribou (Rangifer tarandus L.) in arctic and subarctic Canada. | Effective management and conservation of species, subspecies, or ecotypes require an understanding of how populations are structured in space. We used satellite-tracking locations and hierarchical and fuzzy clustering to quantify subpopulations within the behaviorally different barren-ground caribou (Rangifer tarandus groenlandicus), Dolphin and Union island caribou (R. t. groenlandicus x pearyi), and boreal (R. t. caribou) caribou ecotypes in the Northwest Territories and Nunavut, Canada. Using ... | 2011 | 21939065 |
| divergent parasite faunas in adjacent populations of west greenland caribou: natural and anthropogenic influences on diversity. | gastrointestinal parasite diversity was characterised for two adjacent populations of west greenland caribou (rangifer tarandus groenlandicus) through examinations of abomasa and small intestines collected from adult and subadult females during late winter. three trichostrongyline (trichostrongylina: nematoda) species were identified from the abomasa, although none were recovered from the small intestines, with faunal composition differing between the caribou populations. in caribou from kangerl ... | 2013 | 24533335 |
| development and availability of the free-living stages of ostertagia gruehneri, an abomasal parasite of barrenground caribou (rangifer tarandus groenlandicus), on the canadian tundra. | climate change in the arctic is anticipated to alter the ecology of northern ecosystems, including the transmission dynamics of many parasite species. one parasite of concern is ostertagia gruehneri, an abomasal nematode of rangifer ssp. that causes reduced food intake, weight loss, and decreased pregnancy rates in reindeer. we investigated the development, availability, and overwinter survival of the free-living stages of o. gruehneri on the tundra. fecal plots containing o. gruehneri eggs were ... | 2012 | 22717158 |
| a new eimeria species (protozoa: eimeriidae) from caribou in ameralik, west greenland. | fecal samples of 11 calves shot in the ameralik area, west greenland, in august-september 2014 were examined for coccidian parasites. the calves belonged to a population of interbreeding indigenous caribou rangifer tarandus groenlandicus and feral semi-domestic norwegian reindeer rangifer tarandus tarandus. two coccidian species were found: eimeria rangiferis and a coccidium that was identified and described as a new species. the latter's sporulated oocyst is spherical or slightly subspherical. ... | 2016 | 26758447 |
