helminths in coyotes (canis latrans say), wolves (canis lupus l.), and red foxes (vulpes vulpes l.) of southwestern manitoba.		1978	751709
diseases and parasites in wolves of the riding mountain national park region, manitoba, canada.	we examined wolf (canis lupus) blood and fecal samples from the riding mountain national park (rmnp) region of manitoba, canada. in 601 fecal samples collected during two study periods in rmnp and the duck mountain provincial park and forest (dmppf) we found gastrointestinal helminth eggs from alaria sp. (15.5%), capillaria sp. (1.0%), taeniid tapeworms (30.8%), toxascaris sp. (1.7%), toxocara sp. (0.2%), trichuris sp. (2.2%), and moniezia sp. (0.5%). in addition, we found demodex sp. (0.2%) and ...	2011	21270013
Landscape resistance to dispersal: simulating long-term effects of human disturbance on a small and isolated wolf population in southwestern Manitoba, Canada.	Landscape fragmentation affects wildlife population viability, in part, through the effects it has on individual dispersal. In addition, some forms of human disturbance impinge on dispersal without physically fragmenting habitats. Here, we use the term "landscape resistance" to capture constraints to dispersal that cannot be linked directly to fragmentation. The extent to which landscape resistance can influence population persistence is not well understood. Agricultural development over the pas ...	2011	22146824
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
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
alternative prey use affects helminth parasite infections in grey wolves.	predators affect prey populations not only through direct predation, but also by acting as definitive hosts for their parasites and completing parasite life cycles. understanding the affects of parasitism on prey population dynamics requires knowing how their predators' parasite community is affected by diet and prey availability. ungulates, such as moose (alces americanus) and white-tailed deer (odocoileus virginianus), are often important prey for wolves (canis lupus), but wolves also consume ...	2016	27155132
