Boreal wetlands play an important role in global carbon balance. However, their ecosystem function is threatened by direct anthropogenic disturbance and climate change. Oil sands surface mining in the boreal regions of Western Canada denudes tracts of land of organic materials, leaves large areas...

Forage yield and quality of chicory, birdsfoot trefoil, and alfalfa during the establishment year
Download2008
Bork, E. W., Donkor, N., Hudson, R., Chapman, G.
As part of a study to evaluate alternative forages for farmed deer, we compared forage yields and quality of birdsfoot trefoil (Lotus corniculatus) and forage chicory (Cichorium intybus) with that of alfalfa (Medicago sativa) in north central Alberta, Canada. Despite similar plant densities among...

Abstract. Drought stress can cause xylem embolism in trees when the water potential (W)in the xylem falls below specific vulnerability thresholds. At the alpine timberline, frostdrought is known to cause excessive winter embolism unless xylem vulnerability ortranspiration is sufficiently reduced to...

Drought stress can cause xylem embolism in trees when the water potential (Psi) in the xylem falls below specific vulnerability thresholds. At the alpine timberline, frost drought is known to cause excessive winter embolism unless xylem vulnerability or transpiration is sufficiently reduced to...

Functional diversity is an important concept in community ecology because it captures information on functional traits absent in measures of species diversity. One popular method of measuring functional diversity is the dendrogram-based method, FD. To calculate FD, a variety of methodological...

Cumming, S. G., Schmiegelow, F. K. A., Burton, P. J.
Trembling aspen (Populus tremuloides) in western Canadian boreal forests is generally believed to occur as young, even-aged stands, as part of a fire-dominated landscape. However, the available quantitative estimates of the rate of disturbance by fire in this region differ markedly. One estimate...

Dhir, N., Rweyongeza, D., Yeh, F.
We estimated heritabilities and correlations for bud flushing and growth traits of white spruce seedlings, and the correlations of seedling traits with 10- and 11-year height of the same families in the field. The seedling greenhouse experiment had a randomized complete block design with 30...

Genetic variation in height, branch and needle lengths of Pinus sylvestris L. from Siberia tested in Alberta, Canada
Download2003
Dhir, N.K., Rweyongeza, D., Yeh, F.C., Dancik, B.P.
We performed the analysis of variance and covariance on height, branch length, height to branch length ratio, and needle length measurements from thirty open-pollinated families of Pinus sylvestris L. from Siberia, Russia. This progeny trial was replicated on three sites in central Alberta,...
