fluorosis in black-tailed deer.marked dental disfigurement and abnormal tooth wear patterns were observed in black-tailed deer (odocoileus hemionus columbianus) taken from an area near an industrial fluoride source in northwestern washington. fluoride levels in the bones of these deer were from 10 to 35 times higher than levels in the bones of normal animals. these levels are similar to those associated with fluorosis of cattle.19761255910
muscleworms, parelaphostrongylus andersoni (nematoda: protostrongylidae), discovered in columbia white-tailed deer from oregon and washington: implications for biogeography and host associations.parelaphostrongylus andersoni is considered a characteristic nematode infecting white-tailed deer (odocoileus virginianus). host and geographic distribution for this parasite, however, remain poorly defined in the region of western north america. fecal samples collected from columbia white-tailed deer (o. v. leucurus) in a restricted range endemic to oregon and washington, usa, were examined for dorsal-spined larvae characteristic of many protostrongylid nematodes. multilocus dna sequence data ( ...200818263818
anticipating forest and range land development in central oregon (usa) for landscape analysis, with an example application involving mule deer.forest policymakers, public lands managers, and scientists in the pacific northwest (usa) seek ways to evaluate the landscape-level effects of policies and management through the multidisciplinary development and application of spatially explicit methods and models. the interagency mapping and analysis project (imap) is an ongoing effort to generate landscape-wide vegetation data and models to evaluate the integrated effects of disturbances and management activities on natural resource condition ...201020300934
bovicola tibialis (phthiraptera:trichodectidae): occurrence of an exotic chewing louse on cervids in north america.through a recent (2003-2007) survey of ectoparasites on hoofed mammals in western north america, a literature review, and examination of archived museum specimens, we found that the exotic deer-chewing louse, bovicola tibialis (piaget), is a long-term, widespread resident in the region. the earliest known collection was from salt spring island, canada, in 1941. we found these lice on the typical host, that is, introduced european fallow deer (dama dama l.), and on asian chital (axis axis [erxleb ...201121337942
hair-loss syndrome in black-tailed deer of the pacific northwest.a widespread hair-loss syndrome (hls) has affected columbian black-tailed deer (odocoileus hemionus columbianus) in western oregon and washington (usa) since 1996. in order to better characterize the condition, 21 hls-affected black-tailed deer (btd) were necropsied, and body condition, parasite burdens, and significant lesions were noted. all deer were in poor body condition, and at least 17 had severe internal parasite burdens. a consistent finding was the presence of large numbers of chewing ...200415650084
hybrid swarm between divergent lineages of mule deer (odocoileus hemionus).studies of hybrid zones have revealed an array of evolutionary outcomes, yet the underlying structure is typically characterized as one of three types: a hybrid zone, a hybrid swarm or a hybrid taxon. our primary objective was to determine which of these three structures best characterizes a zone of hybridization between two divergent lineages of mule deer (odocoileus hemionus), mule deer and black-tailed deer. these lineages are morphologically, ecologically and genetically distinct, yet hybrid ...201122066874
eimeria odocoilei n. sp. from the mule deer odocoileus h. hemionus in washington. 19676069253
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
serologic, trace element, and fecal parasite survey of free-ranging, female mule deer (odocoileus hemionus) in eastern washington, usa.blood and fecal samples collected from 97 free-ranging mule deer (odocoileus hemionus), from four distinct herds during the spring of 2000 or 2001 in eastern washington, us, were tested for exposure to selected pathogens, concentrations of trace elements, and presence of parasites in feces. antibodies were detected to the following: leptospira interrogans serovar bratislava (4%), leptospira interrogans serovar canicola (1%), leptospira interrogans serovar grippotyphosa (13%), bovine viral diarrh ...201525380366
testicular atrophy in a mule deer population.monitoring mule deer (odocoileus hemionus) on a former plutonium production site along the columbia river at the hanford site, washington (usa) revealed 27 (23%) of 116 adult males had unusually shaped, velvet-covered antlers and abnormally developed testicles. we captured 32 males to examine age-class differences and the ratio of affected to unaffected deer and determine whether affected testicles were atrophic or hypoplastic. we found testicular atrophy in most deer with velvet-covered antlers ...19979249686
