| 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 |
| prey specialization may influence patterns of gene flow in wolves of the canadian northwest. | this study characterizes population genetic structure among grey wolves (canis lupus) in northwestern canada, and discusses potential physical and biological determinants of this structure. four hundred and ninety-one grey wolves, from nine regions in the yukon, northwest territories and british columbia, were genotyped using nine microsatellite loci. results indicate that wolf gene flow is reduced significantly across the mackenzie river, most likely due to the north-south migration patterns of ... | 2001 | 11903892 |
| cadmium, copper, iron, and zinc concentrations in kidneys of grey wolves, canis lupus, from alaska, idaho, montana (usa) and the northwest territories (canada). | cadmium, copper, iron, and zinc levels were measured in the kidneys of 115 grey wolves (canis lupus) from idaho, montana and alaska (united states), and from the northwest territories (canada). no significant differences in the levels of iron or copper were observed between locations, but wolf kidneys from more northern locations had significantly higher cadmium levels (alaska > northwest territories > montana ≈ idaho), and wolves from alaska showed significantly higher zinc than other locations ... | 2010 | 20972865 |
| prevalence of trichinella spp. in black bears, grizzly bears, and wolves in the dehcho region, northwest territories, canada, including the first report of t. nativa in a grizzly bear from canada. | samples of muscle from 120 black bears (ursus americanus), 11 grizzly bears (ursus arctos), and 27 wolves (canis lupus) collected in the dehcho region of the northwest territories from 2001 to 2010 were examined for the presence of trichinella spp. larvae using a pepsin-hcl digestion assay. trichinella spp. larvae were found in eight of 11 (73%) grizzly bears, 14 of 27 (52%) wolves, and seven of 120 (5.8%) black bears. the average age of positive grizzly bears, black bears, and wolves was 13.5, ... | 2011 | 21719845 |
