| 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 |
| new records of hair follicle mites (demodecidae) from north american cervidae. | individuals of three species of cervids, with varying degrees of alopecia, were examined for ectoparasites: rocky mountain elk (cervus elaphus nelsoni) and mule deer (odocoileus hemionus hemionus) in colorado and white-tailed deer (odocoileus virginianus) in south dakota. hair follicle mites were recovered and identified as demodex kutzeri, a species originally described from the european red deer (cervus elaphus, from austria) and the sika deer (cervus nippon pseudaxis, captive in germany). the ... | 2010 | 20688655 |
| mitochondrial dna analysis of hybridization between sympatric white-tailed deer and mule deer in west texas. | sympatric populations of white-tailed deer and mule deer (odocoileus virginianus and odocoileus hemionus, respectively) on a west texas ranch share a common mitochondrial dna restriction map genotype. phylogenetic analysis indicates that this genotype is more characteristic of o. virginianus than of o. hemionus. the genotype of west texas deer differs from that of o. virginianus from south carolina by five mutational events (1.3% sequence divergence), whereas it differs from that of o. hemionus ... | 1986 | 3467326 |
