g-band patterns, hemoglobin, and transferrin types of the bharal: chromosomal evolutionary relationships with sheep and goats.g-band patterns of the bharal (pseudois nayaur), 2n = 54, were compared with those of wild sheep (ovis dalli stonei), 2n = 54, and the persian wild goat (capra hircus), 2n = 60. patterns of the longer segments of the biarmed chromosomes of pseudois were similar to those of the longer biarmed segments of ovis, whereas the shorter segments differed. biarmed chromosomal segments had g-band homologies with specific acrocentric autosomes of capra and were ranked as follows in descending order of rela ...1978744872
acute monensin toxicosis in stone sheep (ovis dalli stonei), blesbok (damaliscus dorcus phillipsi), and a bactrian camel (camelus bactrianus).accidental monensin toxicosis developed in 5 stone sheep (ovis dalli stonei), 5 blesbok (damaliscus dorcas phillipsi), and a bactrian camel (camelus bactrianus) at the st louis zoological park. eight animals died acutely and 1 was euthanatized because of chronic hind limb paresis. all affected animals had clinicopathologic evidence of severe muscle necrosis, serum electrolyte disturbances, and hemoconcentration.19902295548
contact transmission of psoroptic mange from bighorn to stone sheep.psoroptes sp. mites and tan crusty lesions were detected in the ears of a captive stone sheep (ovis dalli stonei) in april 1996, after contact with infected captive rocky mountain bighorn sheep (ovis canadensis canadensis). psoroptes spp. have not been detected in free-ranging ungulates in canada or alaska (usa). this is the first report of psoroptes sp. in stone sheep, indicating their susceptibility to infection.19979249721
muskox lungworm (umingmakstrongylus pallikuukensis) does not establish in experimentally exposed thinhorn sheep (ovis dalli).muskoxen (ovibos moschlatus moschatus) on the northwestern mainland of nunavut and northwest territories, canada, are infected with the protostrongylid lungworm, umingmaksrongylus pallikuuhkensis. the geographic range of this muskox population is expanding to the south and west, and it is anticipated that these animals will eventually become sympatric with dall's sheep (ovis dalli dalli) in the mackenzie and richardson mountains. to address the concern of wildlife managers that u. pallikulkensis ...200415362818
bilateral perirenal hemorrhage in two stone's sheep (ovis dalli stonei): a possible manifestation of malignant catarrhal fever.malignant catarrhal fever (mcf)-like disease was diagnosed at postmortem in 2 stone's sheep (ovis dalli stonei). on gross examination, the predominant abnormality in both sheep was severe perirenal hemorrhage and multiple renal infarcts. microscopically, there was severe, multisystemic lymphocytic arteritis. both sheep were positive for ovine herpesvirus 2 (ovhv-2) on polymerase chain reaction, and partial sequencing of the viral dna polymerase genes from the 2 sheep revealed >99% homology, with ...200818776110
changes in horn size of stone's sheep over four decades correlate with trophy hunting pressure.selective harvest may lead to rapid evolutionary change. for large herbivores, trophy hunting removes males with large horns. that artificial selection, operating in opposition to sexual selection, can lead to undesirable consequences for management and conservation. there have been no comparisons of long-term changes in trophy size under contrasting harvest pressures. we analyzed horn measurements of stone's rams (ovis dalli stonei) harvested over 37 years in two large regions of british columb ...201627039527
