| 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 |
| metorchis conjunctus (cobbold, 1860) infection in wolves (canis lupus), with pancreatic involvement in two animals. | the trematode metorchis conjunctus (cobbold, 1860) was found in seven of 211 wolves from saskatchewan which were examined between 1976 and 1983. the parasite caused cholangiohepatitis with periductular fibrosis in the liver of all the wolves, and chronic inflammation and fibrosis of the pancreas in two animals. the wolves with pancreatic involvement were emaciated. five of the seven infected wolves were from one local area, and three of these were from a pack known to consume fish. | 1983 | 6644936 |
| echinococcus multilocularis and echinococcus canadensis in wolves from western canada. | echinococcus species are important parasites of wildlife, domestic animals and people worldwide; however, little is known about the prevalence, intensity and genetic diversity of echinococcus tapeworms in canadian wildlife. echinococcus tapeworms were harvested from the intestines of 42% of 93 wolves (canis lupus) from five sampling regions in the northwest territories, manitoba and saskatchewan, and visually identified to genus level by microscopic examination. genetic characterization was succ ... | 2014 | 24135428 |
| introduced and native haplotypes of echinococcus multilocularis in wildlife in saskatchewan, canada. | recent detection of a european-type haplotype of the cestode echinococcus multilocularis in a newly enzootic region in british columbia prompted efforts to determine if this haplotype was present elsewhere in wildlife in western canada. in coyote (canis latrans) definitive hosts in an urban region in central saskatchewan (sk), we found a single haplotype of e. multilocularis that was most similar to a haplotype currently established in the core of this parasite's distribution in europe and to th ... | 2015 | 26020284 |
| traumatic, degenerative, and developmental lesions in wolves and coyotes from saskatchewan. | a retrospective review was done of traumatic and osseous lesions in 241 wolves (canis lupus) and 316 coyotes (canis latrans) necropsied at the university of saskatchewan between 1971 and 1990. most lesions were the result of interspecific conflict. the most frequently occurring lesion in wolves was fracture of one or more bones, primarily ribs. lesions were healed in most cases and appeared to be compatible with injuries caused by prey animals. one wolf, found dead, died as a result of thoracic ... | 1992 | 1602579 |
