The potential of aspen clonal forestry in Alberta: breeding regions and estimates of genetic gain from selection
Download2012
Brouard, J.S., Hamann, A., Gylander, T., Thomas, B.R.
Background: Aspen naturally grows in large, single-species, even-aged stands that regenerate clonally after fire disturbance. This offers an opportunity for an intensive clonal forestry system that closely emulates the natural life history of the species. In this paper, we assess the potential of...

The Push-Pull Tactic for Mitigation of Mountain Pine Beetle (Coleoptera: Curculionidae) Damage in Lodgepole and Whitebark Pines
Download2012
Wood, D.L., Erbilgin, N., Mehmel, C.J., Gillette, N.E., Mori, S.R., Owen, D.R., Webster, J.N.
In an attempt to improve semiochemical-based treatments for protecting forest stands from bark beetle attack, we compared push-pull versus push-only tactics for protecting lodgepole pine (Pinus contorta Douglas ex Loudon) and whitebark pine (Pinus albicaulis Engelm.) stands from attack by...

Purdy, B. G., Dale, M. R. T., MacDonald, S. E.
Abstract: Early establishment of white spruce (Picea glauca) in mixedwood boreal forest stands following fire was examined at several times-since-fire (1-, 2-, 4-, 6-, 14-years). Abiotic and biotic conditions in the stands were assessed at two scales, tree plot (5 in x 5 in) and microsite (1 m x...

The Restorative Imperative: Challenges, objectives and approaches to restoring naturalness in forests
Download2011
Burton, P. J., MacDonald, S. E.
Abstract: Many of the world's forests are not primeval; forest restoration aims to reverse alterations caused by human use. Forest restoration (including reforestation and forest rehabilitation) is widely researched and practiced around the globe. A review of recent literature reveals some common...

The role of historical fire disturbance in the carbon dynamics of the pan-boreal region: A process-based analysis
Download2007
Apps, M., Zhuang, Q., Burnside, T.J., Shvidenko, A., Flannigan, M., McAllister, J., Wirth, C., Clein, J.S., Balshi, M.S., Kurz, W.A., Kicklighter, D.W., Harden, J., McGuire, A.D., Kasischke, E., Melillo, J.
Wildfire is a common occurrence in ecosystems of northern high latitudes, and changes in the fire regime of this region have consequences for carbon feedbacks to the climate system. To improve our understanding of how wildfire influences carbon dynamics of this region, we used the process-based...

The role of water channel proteins in facilitating recovery of leaf hydraulic concutance from water stress in Populus trichocarpa
Download2014
Gas exchange is constrained by the whole-plant hydraulic conductance (Kplant). Leaves account for an important fraction of Kplant and may therefore represent a major determinant of plant productivity. Leaf hydraulic conductance (Kleaf) decreases with increasing water stress, which is due to xylem...

The soil microbial community and grain micronutrient concentration of historical and modern hard red spring wheat cultivars grown organically and conventionally in the Black soil zone of the Canadian prairies
Download2011
Nelson, A. G., Spaner, D. M., Frick, B., Clapperton, M.J., Hucl, P. J., Thavarajah, D., Quideau, S. A.
Abstract: Micronutrient deficiencies in the diet of many people are common and wheat is a staple food crop, providing a carbohydrate and micronutrient source to a large percentage of the world’s population. We conducted a field study to compare five Canadian red spring wheat cultivars (released...

The standard centrifuge method accurately measures vulnerability curves of longvesselled olive stems
Download2015
Venturas, M.D., Sperry, J.S., Hacke, U.G., Pratt, R.B. , Jacobsen, J.S., MacKinnon, E.D.
The standard centrifuge method has been frequently used to measure vulnerability to xylem cavitation. This method has recently been questioned. It was hypothesized that open vessels lead to exponential vulnerability curves, which were thought to be indicative of measurement artifact. We tested...

The Three Gorges Dam in China is the largest dam ever built. Its impacts on the biodiversity and ecological processes in the region are causing concern to ecologists worldwide. The dam and associated environmental alterations may result in a number of regional changes in terrestrial and aquatic...
