capture of free-ranging mule deer (odocoileus hemionus) with a combination of medetomidine, azaperone, and alfaxalone.	the combination of medetomidine, azaperone, and alfaxalone has been successfully used to anesthetize captive white-tailed deer ( odocoileus virginianus ). this same combination was utilized to immobilize free-ranging female mule deer ( odocoileus hemionus ; md) in urban and nonurban environments (14 urban md, 14 nonurban md) in british columbia, canada. physiologic data were collected to assess the safety and reliability of this drug combination under field conditions. each deer received estimat ...	2017	28151080
an expanding population of the giant liver fluke (fascioloides magna) in elk (cervus canadensis) and other ungulates in canada.	giant liver fluke (fascioloides magna) populations readily expand under suitable conditions. although extirpated from the eastern slopes of the canadian rocky mountains in the early 1960s, the fluke reappeared following natural spread through mountain passes from british columbia. herein, we assessed epizootiology of the fluke population two decades later. between 1984 and 1991, 534 ungulates, including 381 elk (cervus canadensis), 68 mule deer (odocoileus hemionus hemionus), 54 white-tailed dee ...	2015	25647594
Molecular Study of Free-ranging Mule Deer and White-tailed Deer from British Columbia, Canada, for Evidence of Anaplasma spp. and Ehrlichia spp.	Twenty-three free-ranging white-tailed deer (WTD; Odocoileus virginianus) and six mule deer (MD; Odocoileus hemionus) from south-central British Columbia, Canada, were tested for Anaplasma marginale by msp5 gene-specific PCR and Ehrlichia spp. by 16S rRNA or citrate synthase (gltA) gene-specific PCR, as well as by PCR with universal 16S rRNA primers detecting a wide range of bacteria. No deer tested positive for A. marginale. Amplification with universal 16S rRNA primers followed by sequencing o ...	2011	21933360
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 ...	2011	21337942
identification of parelaphostrongylus odocoilei (nematoda: protostrongylidae) first-stage larvae in the feces of gray wolves (canis lupus) by molecular methods.	first-stage nematode larvae with a dorsal-spine (dsl) were detected in five of 1,565 fecal samples from gray wolves (canis lupus) collected in british columbia, canada, between 2005 and 2008. molecular techniques were used to identify the dsl because it was not possible to determine their species identity using morphologic characters. the dsl were identified as parelaphostrongylus odocoilei based on the results of single-strand conformation polymorphism (sscp) analyses and dna sequencing of the ...	2010	20090048
spawning salmon disrupt trophic coupling between wolves and ungulate prey in coastal british columbia.	as a cross-boundary resource subsidy, spawning salmon can strongly affect consumer and ecosystem ecology. here we examine whether this marine resource can influence a terrestrial wolf-deer (canis lupus-odocoileus hemionus) predator-prey system in coastal british columbia, canada. data on resource availability and resource use among eight wolf groups for three seasons over four years allow us to evaluate competing hypotheses that describe salmon as either an alternate resource, consumed in areas ...	2008	18764930
geographic distribution of the muscle-dwelling nematode parelaphostrongylus odocoilei in north america, using molecular identification of first-stage larvae.	molecular identification of dorsal-spined larvae (dsl) from fecal samples indicates that the protostrongylid parasite parelaphostrongylus odocoilei occupies a broader geographic range in western north america than has been previously reported. we analyzed 2,124 fecal samples at 29 locations from thinhorn sheep (ovis dalli dalli and o. d. stonei), bighorn sheep (ovis canadensis canadensis and o. c. californiana), mountain goats (oreamnos americanus), woodland caribou (rangifer tarandus caribou), ...	2005	16108550
