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 seq...
متن کاملPhylogeographical Analysis of mtDNA Data Indicates Postglacial Expansion from Multiple Glacial Refugia in Woodland Caribou (Rangifer tarandus caribou)
Glacial refugia considerably shaped the phylogeographical structure of species and may influence intra-specific morphological, genetic, and adaptive differentiation. However, the impact of the Quaternary ice ages on the phylogeographical structure of North American temperate mammalian species is not well-studied. Here, we surveyed ~1600 individuals of the widely distributed woodland caribou (Ra...
متن کاملSarcocystis in caribou (Rangifer tarandus terraenorae) in Newfoundland.
Prevalence of species of Sarcocystis in muscle of 36 caribou, Rangifer tarandus terraenorae, shot in Newfoundland, Canada, was 53%. A greater percentage of infected animals were obtained from the central part of the island. The highest concentration of microscopic sarcocysts, 1/mm2 of tissue, was observed in a 5-year old animal. Although widely distributed throughout the body, cysts were more p...
متن کاملGenetic variation in caribou and reindeer (Rangifer tarandus).
Genetic variation at seven microsatellite DNA loci was quantified in 19 herds of wild caribou and domestic reindeer (Rangifer tarandus) from North America, Scandinavia and Russia. There is an average of 2.0-6.6 alleles per locus and observed individual heterozygosity of 0.33-0.50 in most herds. A herd on Svalbard Island, Scandinavia, is an exception, with relatively few alleles and low heterozy...
متن کاملThe Future of Peary Caribou (Rangifer tarandus pearyi) in a Changing Climate
In the last half century, trends in mean temperature (increasing), snowfall (increasing), and snow cover (decreasing) that are consistent with global warming predictions have been observed in the Arctic (Brown and Alt 2001; Gitay et al. 2002; Whitfield et al. 2002). Additionally, climate variability in the Arctic has increased: there has been a significant increase in the number of thaw days in...
