| geographic distribution of the muscle-dwelling nematode parelaphostrongylus odocoilei in north america, using molecular identification of first-stage larvae. | molecular identification of dorsal-spined larvae (dsl) from fecal samples indicates that the protostrongylid parasite parelaphostrongylus odocoilei occupies a broader geographic range in western north america than has been previously reported. we analyzed 2,124 fecal samples at 29 locations from thinhorn sheep (ovis dalli dalli and o. d. stonei), bighorn sheep (ovis canadensis canadensis and o. c. californiana), mountain goats (oreamnos americanus), woodland caribou (rangifer tarandus caribou), ... | 2005 | 16108550 |
| 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 |
