| intrapopulation variation in gray wolf isotope (delta(15)n and delta(13)c) profiles: implications for the ecology of individuals. | trophic relationships among organisms in terrestrial boreal ecosystems define ecological communities and are important in determining dynamics of energy flow and ecosystem function. we examined trophic relationships between the gray wolf (canis lupus) and 18 mammalian species from the boreal forest of central saskatchewan, canada, using delta(13)c and delta(15)n stable isotope values measured in guard hair samples. variance in isotope values for wolves and other carnivores was investigated as a ... | 2005 | 15883848 |
| sheep-associated malignant catarrhal fever in free-ranging moose (alces alces) in saskatchewan, canada. | malignant catarrhal fever (mcf) is a sporadic disease of artiodactyls caused by several viruses in the gammaherpesvirinae. we report two cases of mcf in free-living moose (alces alces) from saskatchewan. one was a thin, dehydrated, adult male found recumbent in 2006. at necropsy, ulcers were found in the intestine, bladder, and corneas. microscopically, there was lymphocytic vasculitis and perivasculitis in many organs with infrequent fibrinoid necrosis. ovine herpes virus-2 (ohv-2) was identifi ... | 2009 | 19204352 |
| pathology of ocular lesions in free-living moose (alces alces) from saskatchewan. | clinical signs of impaired vision or neurological disease occurred in seven of 74 free-living moose (alces alces) from saskatchewan, canada, submitted for necropsy between 1969 and 1994. several lesions were found in each eye, including retinal degeneration (seven cases), cataract (six cases), lymphocytic-plasmacytic anterior uveitis (six cases), corneal scars (six cases), keratitis (four cases), and microphthalmia (one case), but their cause was not determined. moraxella bovis was isolated from ... | 1997 | 9027695 |
