This study addresses the need to provide comprehensive historical climate data and climate change projections at a scale suitable for, and readily accessible to, researchers and resource managers. This database for western North America (WNA) includes over 20 000 surfaces of monthly, seasonal,...
Daily steps are low year-round and dip lower in fall/winter: Findings from a longitudinal diabetes cohortDownload
Background Higher walking levels lead to lower mortality in type 2 diabetes, but inclement weather may reduce walking. In this patient population, we conducted a longitudinal cohort study to objectively quantify seasonal variations both in walking and in two vascular risk factors associated with...
Effect of horticultural oil on oviposition behaviour and egg survival in the obliquebanded leafroller (Lepidoptera: Tortricidae)Download
Abstract: The effects of the horticultural oil Purespray Green on oviposition behaviour and egg development in the obliquebanded leafroller, Choristoneura rosaceana (Harris), were investigated through dual-choice and no-choice bioassays and topical applications of oil to developing eggs. A...
Effects of Habitat Fragmentation on Pairing Success of Ovenbirds: Importance of Male Age and Floater BehaviorDownload
Between 1996 and 1998, we compared pairing success of territorial male Ovenbirds (Seiurus aurocapillus) in forest fragments created by forestry (n 5 3) and agriculture (n 5 10) to contiguous forest plots (n 5 3) in the southern boreal mixedwood forest of central Saskatchewan. The percentage of...
Effects of crop rotation and genetically modified herbicide-tolerant corn on ground beetle diversity, community structure and activity densityDownload
Ground beetles (Coleoptera. Carabidae) were sampled in conventional and genetically modified herbicide-tolerant (GM HT) corn, Zea mays L. (Poaceae), planted under rotation with canola, Brassica L. (Brassicaceae), or continuously cropped corn to investigate the influence of corn variety and...
Evaluation of Highway Mitigation on the Frequency of Wildlife-Vehicle Collisions on the Highway and an Adjacent Railway in a Montane EcosystemDownload
Transportation networks are expanding rapidly to meet increasing global demands to move people and cargo. These networks are essential to connect societies and economies but have several negative effects on wildlife populations including collisions with vehicles. Growing incidences and increasing...
Background: HIV infection is a serious concern in the Canadian Aboriginal population, particularly among youth; however, there is limited attention to this issue in research literature. The purpose of this national study was to explore HIV testing and care decisions of Canadian Aboriginal youth. ...
Mitochondrial cytochrome oxidase I and 11 genes were sequenced for two invasive alien birch (Betula L. [Betulaceae]) leaf-mining sawflies, Profenusa thomsoni (Konow, 1886) (Hymenoptera: Tenthredinidae) and Scolioneura betuleti (King, 1816) (Hymenoptera: Tenthredinidae), accidentally introduced...
Performance and stability of performance of spring wheat variety mixtures in organic and conventional management systems in western CanadaDownload
Wheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining and stabilizing yield for both organic and conventional producers. The present study examined the responses of three Canadian western red spring wheat varieties in sole crop and in variety...
High concentrations of polychlorinated biphenyls (PCBs) in polar bears from Svalbard have increased concern for that population’s reproductive health. We examined whether there were associations between the plasma concentrations of PCBs and reproductive hormones [progesterone (P4) and...
