evaluation of free-roaming mule deer as carriers of anaplasmosis in an area of idaho where bovine anaplasmosis is enzootic.samples of blood from 87 rocky mountain mule deer (odocoileus hemionus hemionus) were inoculated into 3 susceptible splenectomized calves to determine the anaplasmosis carrier status of the deer. the deer were trapped along the idaho-utah state boundary, near stone, id. acute anaplasmosis was induced in 2 of the 3 inoculated calves, and blood from the 3 calves caused anaplasmosis when inoculated into adult non-splenectomized cattle. serum rapid card agglutination testing revealed 13 (14.9%) posi ...1977833034

vitreous humor analysis for selected biochemical parameters from cervids in idaho.vitreous humor and liver samples were collected from hunter-harvested elk (cervus elaphus) and mule deer (odocoileus hemionus) in idaho (usa). concentrations of calcium, chloride, potassium, sodium, urea nitrogen and selenium were determined and evaluated according to species, age, gender, geographic location, and time elapsed following death. vitreous humor analysis yielded reliable biochemical information for < or = 96 hr subsequent to the death of the animal. vitreous potassium concentration ...19979391961
deer exposed to exceptionally high concentrations of lead near the continental mine in idaho, usa.habitat surrounding the inactive continental mine in northern idaho, usa, supports bear (ursus arctos, ursus americanus), moose (alces alces), elk (cervus elaphus), woodland caribou (rangifer tarandus caribou), and abundant mule (odocoileus hemionus) and white-tailed deer (odocoileus virginianus). tailings on the mining site were capped and remediated in 2003 to reduce environmental exposure of surrounding soil and sediments of blue joe creek, downslope of the mine. before capping, the mean pb c ...200717521153
echinococcus granulosus in gray wolves and ungulates in idaho and montana, usa.we evaluated the small intestines of 123 gray wolves (canis lupus) that were collected from idaho, usa (n=63), and montana, usa (n=60), between 2006 and 2008 for the tapeworm echinococcus granulosus. the tapeworm was detected in 39 of 63 wolves (62%) in idaho, usa, and 38 of 60 wolves (63%) in montana, usa. the detection of thousands of tapeworms per wolf was a common finding. in idaho, usa, hydatid cysts, the intermediate form of e. granulosus, were detected in elk (cervus elaphus), mule deer ( ...200919901399
functional analysis of normalized difference vegetation index curves reveals overwinter mule deer survival is driven by both spring and autumn phenology.large herbivore populations respond strongly to remotely sensed measures of primary productivity. whereas most studies in seasonal environments have focused on the effects of spring plant phenology on juvenile survival, recent studies demonstrated that autumn nutrition also plays a crucial role. we tested for both direct and indirect (through body mass) effects of spring and autumn phenology on winter survival of 2315 mule deer fawns across a wide range of environmental conditions in idaho, usa. ...201424733951
a piecewise linear modeling approach for testing competing theories of habitat selection: an example with mule deer in northern winter ranges.habitat selection fundamentally drives the distribution of organisms across landscapes; density-dependent habitat selection (ddhs) is considered a central component of ecological theories explaining habitat use and population regulation. a preponderance of ddhs theories is based on ideal distributions, such that organisms select habitat according to either the ideal free, despotic, or pre-emptive distributions. models that can be used to simultaneously test competing ddhs theories are desirable ...201323203509
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
