| learning from outbreaks of bovine tuberculosis near riding mountain national park: applications to a foreign animal disease outbreak. | riding mountain national park, manitoba, is home to a population of free-roaming elk (cervus elaphus manitobensis) that have been found to be infected with mycobacterium bovis, the agent of bovine tuberculosis (tb). the disease has also been found in a number of cattle herds near the park and, as a result, manitoba has been assigned a split status for bovine tb. a number of government agencies, with input from representatives from the wildlife and agricultural sectors, have responded by devising ... | 2004 | 14992251 |
| intranasal administration of xylazine to reduce stress in elk captured by net gun. | forty free-ranging elk (cervus elaphus manitobensis) were captured by net gun in riding mountain national park (manitoba, canada) during february 2002 and were administered either saline (control) or xylazine by the intranasal route, to evaluate the efficacy and benefit of intranasal xylazine to reduce stress. elk that received xylazine had higher relaxation scores than control elk, and the onset of sedation occurred quickly, often <1 min. serum concentrations of cortisol, creatine kinase, and g ... | 2004 | 15465726 |
| wildlife reservoirs for bovine tuberculosis (mycobacterium bovis) in canada: strategies for management and research. | in canada, there are two known regional foci where wildlife populations are infected with bovine tuberculosis (mycobacterium bovis) and considered to be disease reservoirs. free-ranging populations of wood bison (bison bison athabascae) in and around wood buffalo national park (wbnp) and wapiti (cervus elaphus manitobensis) in and around riding mountain national park (rmnp) are infected with bovine tuberculosis. in this paper, we provide an overview of these diseased wild ungulate populations an ... | 2006 | 16343817 |
| feasibility of using coyotes (canis latrans) as sentinels for bovine mycobacteriosis (mycobacterium bovis) infection in wild cervids in and around riding mountain national park, manitoba, canada. | elk (cervus elaphus manitobensis) and white-tailed deer (odocoileus virginianus) in the riding mountain national park (rmnp) region of southwestern manitoba have been identified as a likely wildlife reservoir of mycobacterium bovis, the causative agent of bovine mycobacteriosis in livestock. the feasibility of using coyotes (canis latrans) collected from trappers as a sentinel species was investigated. retropharyngeal, mesenteric, and colonic lymph nodes and tonsils collected at necropsy from 82 ... | 2007 | 17699081 |
| physiologic effects of nasal oxygen or medical air administered prior to and during carfentanil-xylazine anesthesia in north american elk (cervus canadensis manitobensis). | this study compared the physiologic effects of carfentanil-xylazine anesthesia in elk administered nasal oxygen or medical air. eight female 5 +/- 2-yr-old (mean +/- sd) captive elk (cervus canadensis manitobensis) weighing 245 +/- 20 kg and habituated to chute restraint were studied in a randomized crossover. nasal insufflation of oxygen or medical air (10 l/min) was provided prior to and throughout anesthesia. baseline data were collected before i.m. injection of carfentanil (10 microg/kg) and ... | 2009 | 19368239 |
| targeting hunter distribution based on host resource selection and kill sites to manage disease risk. | endemic and emerging diseases are rarely uniform in their spatial distribution or prevalence among cohorts of wildlife. spatial models that quantify risk-driven differences in resource selection and hunter mortality of animals at fine spatial scales can assist disease management by identifying high-risk areas and individuals. we used resource selection functions (rsfs) and selection ratios (srs) to quantify sex- and age-specific resource selection patterns of collared (n = 67) and hunter-killed ... | 2013 | 24324876 |
| density-dependent habitat selection and partitioning between two sympatric ungulates. | theory on density-dependent habitat selection predicts that as population density of a species increases, use of higher quality (primary) habitat by individuals declines while use of lower quality (secondary) habitat rises. habitat partitioning is often considered the primary mechanism for coexistence between similar species, but how this process evolves with changes in population density remains to be empirically tested for free-ranging ungulates. we used resource-selection functions to quantif ... | 2014 | 24913777 |
| temporal variation in site fidelity: scale-dependent effects of forage abundance and predation risk in a non-migratory large herbivore. | large herbivores are typically confronted by considerable spatial and temporal variation in forage abundance and predation risk. although animals can employ a range of behaviours to balance these limiting factors, scale-dependent movement patterns are expected to be an effective strategy to reduce predation risk and optimise foraging opportunities. we tested this prediction by quantifying site fidelity of global positioning system-collared, non-migratory female elk (cervus canadensis manitobensi ... | 2013 | 23552985 |
