Adaptive and phenotypic responses of white birch provenances to climate variations
(2009)Trees have adapted to their local climate, but with changes in the climate may currently, or in the near future occupy climates that are sub-optimal for growth and survival. The goal of current reforestation is therefore ... -
Ecophysiological responses of white birch seedlings to soil temperature and phosphorus supply under current and doubled carbon dioxide concentration
(2009)To investigate the responses of some physiological and morphological traits to different soil temperature and phosphorus supply under current and doubled carbon dioxide concentration ([CO2]), white birch (Betula papyrifera ... -
Interactive effects of soil temperature and resource availability on physiological and growth responses of white birch (Betula papyrifera) seedlings to atmospheric carbon dioxide elevation
(2009)Predicting the impacts of future high atmospheric CO2 concentration, [CO2], on the physiology and growth of boreal forests is complicated by interactions of CO2 with other environmental conditions. Two-factor CO2 x environment ... -
Leaf morphological and anatomical variations of paper birch populations along environmental gradients across Canada
(2014-12-12)Leaf morphology and anatomy have been found to vary considerably among tree species, and leaf characteristics have widely been used for analyzing plant growth and resource use strategies because of their structural ... -
Variation in vessel diameter and leaf area of white birch (Betula papyrifera) along moisture gradients in Canada
(2010)One of the key hypotheses of this research is that white birch that has evolved in wet areas will have larger vessels than those trees that evolved in dry areas. Since the wet areas are less likely to experience drought ...
