Are Point Counts of Boreal Songbirds Reliable Proxies for More Intensive Abundance Estimators?
Download2006
Villard, M.-A., Schmiegelow, F.K.A., Hannon, S.J., Toms, J.D.
Point counts are often used to provide information on abundance of songbirds. If data from point counts are to be compared in space or time, however, any bias in the estimate should be consistent and linearly related to the true abundance. Several studies have suggested that this assumption may...

Spring 2019
Trembling aspen (Populus tremuloides Michx.) is a common species in Canadian boreal forests. As a shade intolerant and dynamic species (i.e., stand density and structure change over time), it naturally regenerates by root suckering and grows rapidly. Aspen has a short life compared to spruce or...

Assessing operational silviculture and modeling juvenile growth in Saskatchewan white spruce (Picea glauca (Moench) Voss) plantations
DownloadFall 2015
White spruce (Picea glauca (Moench) Voss) plantations are often established with mechanical site preparation and tending. These silvicultural treatments encourage plantation survival and can influence growth, composition, and yield. To assess operational silviculture and model managed stand...

Assessment of Variation in the Alberta Context Tool: The Contribution of Unit Level Contextual Factors and Specialty in Canadian Pediatric Acute Care Settings
Download2011
Stevens, B., Squires, J.E., Hutchinson, A., Midodzi, W.K., Cummings, G.G., Kang, S.H., Scott, S., Estabrooks, C.A.
Background: There are few validated measures of organizational context and none that we located are parsimonious and address modifiable characteristics of context. The Alberta Context Tool (ACT) was developed to meet this need. The instrument assesses 8 dimensions of context, which comprise 10...

Association between older age and outcome after cardiac surgery: A population-based cohort study
Download2014
Zibdawi, Mohamad, Norris, Colleen M., MacArthur, Roderick, Zibdawi, Rami, Wang, Wei, Bagshaw, Sean M.
Objective Octogenarians (aged???80 years) are increasingly being referred for cardiac surgery. We aimed to describe the morbidity, mortality, and health services utilization of octogenarians undergoing elective cardiac surgery. Methods Retrospective population-based cohort study of adult...

Biology of Caloptilia fraxinella (Lepidoptera: Gracillariidae) on ornamental green ash, Fraxinus pennsylvanica (Oleaceae)
Download2009
Abstract: The ash leaf cone roller, Caloltilia firaxinella (Ely), is a leaf-mining moth that has recently become a significant pest of horticultural ash, Fraxinus L., species in communities throughout the western prairie provinces of Canada. The study examines the spatial and temporal within-host...

Wein, R.W., Cumming, S.G., Flannigan, M.D., Krawchuk, M.A.
Lighting, fire is the dominant natural disturbance of the western mixedwood boreal forest of North America. We quantified the independent effects of weather and forest composition oil lightning fire initiation (a detected and recorded fire start) patterns in Alberta, Canada, to demonstrate how...

Birds of a feather do not always lek together: Genetic diversity and kinship structure of Greater Sage-Grouse (Centrocercus urophasianus) in Alberta
Download2010
Aldridge, C.L., Bush, K.L., Coltman, D.W., Carpenter, J.E., Paszowski, C.A., Boyce, M.S.
Endangered species are sensitive to the genetic effects of fragmentation, small population size, and inbreeding, so effective management requires a thorough understanding of their breeding systems and genetic diversity. The Greater Sage-Grouse (Centrocercus urophasianus) is a lekking species that...

Boreal trees can grow on saline sites – implications for reclamation success on saline soils
Download2015-03-04
Soils from oil sands mining can be affected by salts leached from tailings or overburden materials – resulting in saline soil conditions. As a result, re-establishment of forests on saline sites is an important goal on reclaimed oil sands mines. Forest vegetation is typically thought to be...

Breeding Bird Communities in Boreal Forest of Western Canada: Consequences of "Unmixing" the Mixedwoods
Download2000
Silvicultural practices following clearcutting in boreal forest may encourage the creation of monospecific, single-aged stands having less vegetation heterogeneity and diversity than original stands. We conducted point counts in central Saskatchewan, Canada, 1993–1995, in pure and mixedwood...
