oral papillomatosis in coyotes (canis latrans) and wolves (canis lupus) of alberta.	twelve cases of oral papillomatosis were detected in wild carnivores of alberta, ten in coyotes (canis latrans) and two in wolves (canis lupus). lesions ranged from mild with a few small papillomas to severe with much of the surface of the lips, tongue and buccal cavity covered with papillomas. three of five coyotes with severe papillomatosis were in obvious poor health. the gross and histologic lesions are described and the significance of this disease in wild carnivores is discussed.	1978	650780
sylvatic trichinosis in alberta.	results of surveys for trichinella sp. in several species of wildlife in alberta suggest that infection is limited to wolves (canis lupus) in northern areas of the province and maintained by a wolf/wolf transmission.	1980	7463605
temporal autocorrelation functions for movement rates from global positioning system radiotelemetry data.	autocorrelation has been viewed as a problem in telemetry studies because sequential observations are not independent in time or space, therefore violating assumptions for statistical inference. yet nearly all ecological and behavioural data are autocorrelated in both space and time. we argue that there is much to learn about the structure of ecological and behavioural data from patterns of autocorrelation. such patterns include periodicity in movement and patchiness in spatial data, which can b ...	2010	20566498
oslerus osleri (metastrongyloidea; filaroididae) in gray wolves (canis lupus) from banff national park, alberta, canada.	oslerus osleri is a filaroid parasite of the respiratory tract of canids. in north america, it is most commonly reported from coyotes (canis latrans) and domestic dogs (canis lupus familiaris), but reports in gray wolves (canis lupus) are infrequent. we report a new geographic record for o. osleri in four gray wolves from banff national park, alberta, canada. adult nematodes found in nodules in the submucosa of the trachea and bronchi were identified as o. osleri based on morphometry of spicules ...	2013	23568921
humans strengthen bottom-up effects and weaken trophic cascades in a terrestrial food web.	ongoing debate about whether food webs are primarily regulated by predators or by primary plant productivity, cast as top-down and bottom-up effects, respectively, may becoming superfluous. given that most of the world's ecosystems are human dominated we broadened this dichotomy by considering human effects in a terrestrial food-web. we studied a multiple human-use landscape in southwest alberta, canada, as opposed to protected areas where previous terrestrial food-web studies have been conducte ...	2013	23667705
consequences of a refuge for the predator-prey dynamics of a wolf-elk system in banff national park, alberta, canada.	refugia can affect predator-prey dynamics via movements between refuge and non-refuge areas. we examine the influence of a refuge on population dynamics in a large mammal predator-prey system. wolves (canis lupus) have recolonized much of their former range in north america, and as a result, ungulate prey have exploited refugia to reduce predation risk with unknown impacts on wolf-prey dynamics. we examined the influence of a refuge on elk (cervus elaphus) and wolf population dynamics in banff n ...	2014	24670632
polycyclic aromatic hydrocarbons in caribou, moose, and wolf scat samples from three areas of the alberta oil sands.	impacts of toxic substances from oil production in the alberta oil sands (aos), such as polycyclic aromatic hydrocarbons (pahs), have been widely debated. studies have been largely restricted to exposures from surface mining in aquatic species. we measured pahs in woodland caribou (rangifer tarandus caribou), moose (alces americanus), and grey wolf (canis lupus) across three areas that varied in magnitude of in situ oil production. our results suggest a distinction of pah level and source profil ...	2015	26284348
