Ecophysiological responses of black spruce (Picea mariana) seedlings to nutrient supply, N-P-K ratio and photoperiod at current and elevated CO2 concentration
(2012-11-10)The relationship between plant growth and nitrogen supply is frequently used in growth models to predict growth performance under global climate change scenarios. However, the relationship may be changed under elevated ... -
Effects of Photoperiod, Soil Moisture and Soil Temperature on the Northward Migration Potential of Jack Pine under the Scenario of Doubled Atmospheric CO2 Concentration
(2016)Climate envelope models predict that boreal trees can potentially migrate northward by as much as 10º by 2100 as a consequence of the predicted climate change associated with the doubling of atmospheric CO2 concentration, ... -
Effects of water availability, longer photoperiod, and elevated [CO2] on the potential of the northward migration in trembling aspen (populus tremuloides michx.)
(2019)Based on climate envelope models, boreal tree species may migrate to higher latitudes (approximately 10˚N toward the north) in response to rapid climate changes by the end of this century. Multiple factors will likely ... -
Phenology, growth and physiological responses to photoperiod and elevated [CO2] of boreal white birch (Betula papyrifera Marsh): implications to climate change-induced northward migration
(2019)With the increase in average global temperature due to rising atmospheric carbon dioxide concentration ([CO2]), rapid shifts of climate envelopes are expected to lead to norward migration for boreal tree species. As a ...
