A longitudinal and cross-sectional examination of the relationship between reasons for choosing a neighbourhood, physical activity and body mass index
Download2010
Berry, T. R., Blanchard, C., Selfridge, G., Spence, J. C., Edwards, J., Cutumisu, N.
Abstract: Background: The purpose of this study was to examine the relationship between body mass index and neighborhood walkability, socioeconomic status (SES), reasons for choosing neighborhoods, physical activity, fruit and vegetable intake, and demographic variables. Methods: Two studies,...

Acid-base properties of cyanobacterial surfaces I: Influences of growth phase and nitrogen metabolism on cell surface reactivity
Download2008
Konhauser, K.O., Owttrim, G.W., Smith, D.S., Lalonde, S.V.
Significant efforts have been made to elucidate the chemical properties of bacterial surfaces for the purposes of refining surface complexation models that can account for their metal sorptive behavior under diverse conditions. However, the influence of culturing conditions on surface chemical...

Biological and environmental correlates of cougar (Puma concolor) survival in west central Alberta
DownloadSpring 2023
Large carnivores have a significant role in ecosystems and their role as apex predators can have cascading effects that influence ecosystem stability. Managing large carnivores requires an understanding of how they use the land and their vital rates, including survival. For cougars (Puma...

Broccoli sprout supplementation during placental insufficiency confers structural and functional neuroprotection to the fetal rat
DownloadSpring 2010
Background: Perinatal ischemic brain injury leads to developmental disability (DD), which accounts for 30% of disabilities in children. Antepartum risk, or risk occurring prior to birth occurs in more than 90% of cases. This study investigated whether maternal ingestion of a natural health...

Brown Bear (Ursus arctos) Predation of Broad Whitefish (Coregonus nasus) in the Mackenzie Delta Region, Northwest Territories
Download2009
On 2 October 2007, we observed evidence of at least one brown bear (Ursus arctos) predating and caching broad whitefish (Coregonus nasus) at Pete’s Creek, a tributary of the Mackenzie River, Northwest Territories. While predation on whitefish by brown bears has been reported as traditional...

Peacock, Stephanie J., Connors, Brendan M., Krkošek, Martin, Irvine, James R., Lewis, Mark A.
The impact of parasites on hosts is invariably negative when considered in isolation, but may be complex and unexpected in nature. For example, if parasites make hosts less desirable to predators then gains from reduced predation may offset direct costs of being parasitized. We explore these...

Longrich, N. R., Currie, P. J., Erickson, G. M., Horner, J. R.
Background: Tyrannosaurus rex was one of the largest terrestrial carnivores of all time, and consequently its ecology and diet have been the focus of much discussion. However, there is little direct evidence of diet or feeding habits in this species. Methodology/Principal Findings: Examination...

Climbing simulated vegetation to heights of ungulate hosts by larvae of Dermacentor albipictus (Acari: Ixodidae)
Download2000
Samuel, W. M., Shostak, A. W., McPherson, M.
Abstract: Larvae of winter ticks, Dermacentor albipictus (Packard), ascend vegetation in autumn and form clumps that attach to passing ungulate hosts. We tested the hypothesis that vegetation height determines the height of clumps. During the vegetation-to-ungulate transmission period (early...

We present Van Allen Probes observations of modulations in the flux of very energetic electrons up to a few MeV and protons between 1200 and 1400 UT on 19 February 2014. During this event the spacecraft were in the dayside magnetosphere at L⋆≈5.5. The modulations extended across a wide range of...
