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
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
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
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
