Lodgepole pine, jack pine, and their hybrids: molecular markers reveal mountain pine beetle host-range expansion into jack pine of the boreal forest
Background Lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia) is found in western North America, extending from the Yukon into British Columbia and Washington, and along the Rocky Mountains and eastern slopes to Colorado [1]. Jack pine (Pinus banksiana Lamb.) is a closely related species found east of the Rockies, mainly in Canada’s boreal forest from the Northwest Territories to Qu...
متن کاملCarbon fluxes in a young, naturally regenerating jack pine ecosystem
[1] Within the FLUXNET network of tower stations for performing long-term measurements of CO2 exchange between forest ecosystems and the atmosphere, most research has focused on mature forests that are strong carbon sinks. Nevertheless, it is just as valuable to quantify fluxes from recently disturbed forests so that we can recognize and predict the impact of disturbance on carbon fluxes. We me...
متن کاملSexual expression in container-grown jack pine seedlings.
We assessed the effects of nitrogen, drought and gibberellin A(4/7) on sexual expression of 2- and 3-year-old jack pine (Pinus banksiana L.) seedlings grown in either a 1/3 peat/sand mix or a 3/1 peat/perlite mix. The seedlings were either watered daily (well-watered treatment) or droughted by withholding water from July 13 to August 24 (drought treatment). Half of the plants in each irrigation...
متن کاملEstimating Soil Moisture in a Boreal Old Jack Pine Forest
Polarimetric Land P-band AIRSAR data, corresponding model simulations, and classification algorithms have shown that in a boreal old jack pine (OJP) stand, the principal scattering mechanism responsible for radar backscatter is the double-bounce mechanism between the tree trunks and the ground [1]. The data to be used here were taken during six flights from April to September 1994” as part of t...
متن کاملModeling Jack Pine (Pinus banksiana) Foliage Density Distribution
The vertical distribution of foliage biomass is important because it is associated with photosynthesis and is closely related to some wood quality attributes such as branch diameter and sapwood content. In this article we propose a model to predict foliage biomass distribution within the crown for jack pine trees in Eastern Canada. This model has two parts. The first one distinguishes the propo...
