Adaptation of trembling aspen and hybrid poplars to frost and drought: implications for selection and movement of planting stock in western Canada
DownloadFall 2012
This study contains a series of experiments to evaluate growth performance and survival of hybrid poplars (Populus spp.) and trembling aspen (Populus tremuloides Michx.) in boreal planting environments in western Canada. Ecophysiological traits related to drought resistance and winter survival...

Afforestation and stand age affected soil respiration and net ecosystem productivity in hybrid poplar plantations in central Alberta, Canada
DownloadFall 2010
Afforestation and stand development can significantly affect soil respiration and net ecosystem productivity (NEP). I studied 1) the effects of afforestation on NEP by comparing cropland previously planted to barley (on a barley-barley-alfalfa-alfalfa-alfalfa rotation) and that converted to a...
