| insects feeding on desert bighorn sheep, domestic rabbits, and japanese quail in the santa rosa mountains of southern california. | desert bighorn sheep (ovis canadensis cremnobates), a domestic rabbit (oryctolagus cuniculus), and japanese quail (coturnix japonica) were used as bait animals to collect blood-feeding flies in an area of active blue-tongue and epizootic hemorrhagic disease virus transmission. precipitin tests were used to confirm the blood source where feasible. eight species of culicoides, members of the leptoconops kerteszi group, simulium spp., anopheles franciscanus, and stomoxys calcitrans were collected f ... | 1992 | 1512887 |
| spatial and seasonal distribution of potential vectors of hemorrhagic disease viruses to peninsular bighorn sheep in the santa rosa mountains of southern california. | blood-feeding midges (culicoides sp. and leptoconops sp.) were sampled in the santa rosa mountains, riverside county, california (usa), to determine which species might be involved in the transmission of bluetongue and epizootic hemorrhagic disease viruses to peninsular bighorn sheep (ovis canadensis cremnobates). host-seeking midges were sampled with co2-baited suction traps over a period of 30 mo. nineteen species of culicoides and seven of leptoconops were collected. five of the culicoides sp ... | 1992 | 1602570 |
| osteoporosis and cranial asymmetry in a mountain sheep (ovis canadensis). | the skull of a mountain sheep (ovis canadensis cremnobates) exhibiting osteoporosis was recovered from san diego county, california. this specimen also exhibited lateral asymmetry of the cranium and rostrum, malocclusion of molars, and mandibular asymmetry. investigators are cautioned about potentially confusing lesions associated with chronic frontal sinusitis with lesions of osteoporosis in mountain sheep. to our knowledge this is the first report of osteoporosis in this species. | 1990 | 2388359 |

| restriction endonuclease analysis of herpesviruses isolated from two peninsular bighorn sheep (ovis canadensis cremnobates). | in 1989, herpesviruses were isolated from nasal swabs taken from two peninsular bighorn sheep (ovis canadensis cremnobates) in the anza-borrego desert state park, san diego county, california (usa). using restriction endonuclease analysis (rea) with pst1 enzyme, each isolate was found to be similar to the cooper strain of infectious bovine rhinotracheitis virus (ibrv). the rea patterns of the two herpesviruses from bighorn sheep were typical of either field strains or vaccine strains of ibrv com ... | 1993 | 8383254 |
| waterhole detection using a vegetation index in desert bighorn sheep (ovis canadensis cremnobates) habitat. | in arid ecosystems, desert bighorn sheep are dependent on natural waterholes, particularly in summer when forage is scarce and environmental temperatures are high. to detect waterholes in sierra santa isabel, which is the largest area of desert bighorn sheep habitat in the state of baja california, mexico, we used the normalized difference vegetation index (ndvi) and normalized difference water index (ndwi) from sentinel-2 satellite images. waterhole detection was based on the premise that sites ... | 2019 | 30668602 |
