| prevalence of neutralizing antibody to jamestown canyon virus (california group) in populations of elk and moose in northern michigan and ontario, canada. | blood samples were collected from free-ranging elk (cervus elaphus) harvested in michigan's northern lower peninsula, from moose (alces alces) relocated from ontario's algonquin provincial park to michigan's upper peninsula, and from moose from michigan's isle royale national park. sera were tested by serum dilution neutralization tests in vero cell culture for neutralizing antibody to california serogroup viruses, in particular jamestown canyon (jc), la crosse/snowshoe hare (lac/ssh), and trivi ... | 1986 | 3503129 |
| outbreaks of yersiniosis caused by yersinia pseudotuberculosis in farmed cervids. | yersiniosis, caused by yersinia pseudotuberculosis, was diagnosed in 25 deer submitted to the veterinary diagnostic laboratories of the ontario ministry of agriculture and food from 8 farms in ontario, canada, over the 4-year period of january 1990 to december 1993. the organism was cultured, usually in large numbers, from the intestines and, less frequently, mesenteric lymph nodes and/or the spleen of 13 red deer (cervus elaphus), 6 elk (c. e. canadiensis), 4 fallow deer (dama dama), and 2 red ... | 1995 | 7779969 |
| occupational exposure to mycobacterium bovis infection in deer and elk in ontario. | in late 1991, two herds of deer and elk were depopulated at a slaughtering plant in ontario, followed by processing of infected animals at a rendering plant. we conducted a questionnaire plus tuberculin skin-test survey of 104 exposed slaughtering and rendering plant workers, and government veterinarians and inspectors. overall, 17 participants were skin-test positive, one of 51 initially skin-test negative subjects tested a second time three months later became positive, consistent with the ris ... | 1994 | 7804937 |
| elk restoration in ontario, canada: infectious disease management strategy, 1998-2001. | ontario has embarked upon a program to restore elk (cervus elaphus) that were once native to that province. a comprehensive disease-management strategy has ensured that elk are free of infectious diseases such as brucellosis and tuberculosis prior to shipment to ontario. postmortem analysis occurs on elk mortalities in ontario to ensure that elk are not infected with diseases such as chronic wasting disease and tuberculosis. between 1998 and 2001, a total of 443 elk were transported from elk isl ... | 2002 | 12381618 |
| evidence of parelaphostrongylus tenuis infections in free-ranging elk (cervus elaphus) in southern ontario. | the antemortem detection of a parelaphostrongylus tenuis infection in a free-ranging wild elk (cervus elaphus) in southern ontario is documented. postmortems on other free-ranging elk that died during 2000-2005 indicated that 59% (17/29) were infected with p. tenuis, based on presence of lesions in the brain. | 2007 | 18050795 |
| fitting probability distributions to animal movement trajectories: using artificial neural networks to link distance, resources, and memory. | animal movement paths are often thought of as a confluence of behavioral processes and landscape patterns. yet it has proven difficult to develop frameworks for analyzing animal movement that can test these interactions. here we describe a novel method for fitting movement models to data that can incorporate diverse aspects of landscapes and behavior. using data from five elk (cervus canadensis) reintroduced to central ontario, we employed artificial neural networks to estimate movement probabil ... | 2008 | 18598199 |
| multiple movement modes by large herbivores at multiple spatiotemporal scales. | recent theory suggests that animals should switch facultatively among canonical movement modes as a complex function of internal state, landscape characteristics, motion capacity, and navigational capacity. we tested the generality of this paradigm for free-ranging elk (cervus elaphus) over 5 orders of magnitude in time (minutes to years) and space (meters to 100 km). at the coarsest spatiotemporal scale, elk shifted from a dispersive to a home-ranging phase over the course of 1-3 years after in ... | 2008 | 19060190 |
| bovine tuberculosis in canadian wildlife: an updated history. | mycobacterium bovis infection in wild animals attracted little attention in canada until the disease was almost eliminated from domestic livestock. tuberculosis was endemic in plains bison and occurred in elk, moose, and mule deer in buffalo national park (bnp), alberta during the 1920s and 1930s. bison were moved from bnp to wood buffalo national park (wbnp), where tuberculosis became, and remains, endemic in bison, posing a risk to efforts to restore bison in northern canada. tuberculosis was ... | 2009 | 20119541 |
