iodine-129 in mule deer thyroids in the rocky mountain west.thyroids from mule deer (odocoileus hemionus) were collected in new mexico, colorado, wyoming and idaho and 129i/127i atom ratios were determined. iodine-129/127 atom ratios were significantly (p less than 0.005) different among states. ratios in wyoming and idaho control thyroids were significantly (p less than 0.05) larger than ratios in new mexico and colorado. fallout from past atmospheric nuclear tests at the nevada test site is suggested as a possible explanation for the differences in rat ...19836874350
evaluating apparent competition in limiting the recovery of an endangered ungulate.predation can disproportionately affect endangered prey populations when generalist predators are numerically linked to more abundant primary prey. apparent competition, the term for this phenomenon, has been increasingly implicated in the declines of endangered prey populations. we examined the potential for apparent competition to limit the recovery of sierra nevada bighorn sheep (ovis canadensis sierrae), an endangered subspecies under the us endangered species act. using a combination of loc ...201322791131
cross-sectional study of faecal shedding of giardia duodenalis and cryptosporidium parvum among packstock in the sierra nevada range.faecal specimens from 305 horses and mules used as packstock at one of 17 commercial or governmental (national park service, us forest service) operations were examined for giardia duodenalis and cryptosporidium parvum using immunofluorescent microscopy. fourteen packstock (4.6%) were shedding g. duodenalis cysts, with herd-level prevalences ranging 0-22%. number of packstock in the corral, size of corral and density of packstock in the corral were associated with the odds of shedding g. duodena ...200010836481
isolation and characterization of a novel cervid adenovirus from white-tailed deer (odocoileus virginianus) fawns in a captive herd.a novel adenovirus, ceadv1, was isolated from buffy coat and nasal swab samples collected from two captive white-tailed deer (odocoileus virginianus) fawns. the isolation was an incidental finding in the course of screening animals for use in a research study on an unrelated pathogen. in the screening process, virus isolation was performed on both nasal swabs and buffy coat samples and cytopathic effect was observed. electron microscopy revealed viral particles with the shape and morphology of a ...201728662929
a multi-scale evaluation of pack stock effects on subalpine meadow plant communities in the sierra nevada.we evaluated the influence of pack stock (i.e., horse and mule) use on meadow plant communities in sequoia and yosemite national parks in the sierra nevada of california. meadows were sampled to account for inherent variability across multiple scales by: 1) controlling for among-meadow variability by using remotely sensed hydro-climatic and geospatial data to pair stock use meadows with similar non-stock (reference) sites, 2) accounting for within-meadow variation in the local hydrology using in ...201728609464
detection of relapsing fever spirochetes (borrelia hermsii and borrelia coriaceae) in free-ranging mule deer (odocoileus hemionus) from nevada, united states.abstract surveillance of mule deer (odocoileus hemionus, rafinesque, 1917) populations for tick-borne diseases has helped define the distribution of these pathogens and their subsequent risk of transmission to humans and domestic animals. we surveyed three mule deer herds across the state of nevada for infection with relapsing fever borrelia spp. spirochetes. bacterial prevalence varied by the county where deer were sampled but borrelia spirochetes were detected in 7.7% of all deer sampled. in ...201121995265
exotic pediculosis and hair-loss syndrome in deer (odocoileus hemionus) populations in california.infestation with nonnative, "exotic" lice was first noted in washington black-tailed deer (odocoileus hemionus columbianus) in 1994 and has since then spread throughout the western united states. in california, infestation with the exotic louse damalinia (cervicola) sp. was first detected in black-tailed deer from northern california in 2004, and, in 2009, the exotic louse species bovicola tibialis and linognathus africanus were identified on mule deer (odocoileus hemionus californicus) in centr ...201627240567
influence of vegetation on carbon dioxide trap effectiveness for sampling mosquitoes in the sierra nevada foothills of kern county, california.the effect of vegetation on sampling culex tarsalis, cx. quinquefasciatus and aedes nigromaculis by co2 traps was evaluated at an intermittent stream habitat at the base of the sierra nevada foothills. carbon dioxide traps were spaced along a 450 m transect perpendicular to poso creek to determine female attraction to traps placed in 5 different vegetation substrates: 1) open hilltop with sparse growth of grasses and saltbush, 2) open pasture with sparse growth of saltbush, 3) peripheral underst ...19911791459
