Structure and composition of riparian boreal forest: new methods for analyzing edge influence
Download2001
Abstract: Riparian ecotones at lakeshore edges are prominent features on the heterogeneous boreal forest landscape. We introduce a new method (the critical values approach): which incorporates inherent variability in interior forest, to quantify distance of edge influence at lakeshore forest...

Study of early selection in tree breeding - 3. A case study using early information to enhance selection efficiency in late trait in lodgepole pine (Pinus contorta spp. Latifolia)
Download2000
Wu, H.X., Pharis, R.P., Dhir, N.K., Yeh, F.C., Dancik, B.P.
We present a selection procedure that combines early performance from retrospective study and late performance from field testing into an index designed for enhancing the selection efficiency of the late performance. The prerequisite is that early performance from retrospective study and late...

Sustained Yield Forestry in Sweden and Russia: How Does it Correspond to Sustainable Forest Management Policy?
Download2013
Martin Hermansson, Frederik Doyon, Per Angelstam, Marine Elbakidze, Kjell Andersson, Jonas Jacobsson, Glen W. Armstrong, Robert Axelsson, Yurij Pautov
This paper analyzes how sustained yield (SY) forestry is defined and implemented in Sweden and Russia, two countries with different forest-industrial regimes. We first compare definitions of SY forestry in national legislation and policies. Then we study forest management planning in two large...

Synoptic Scale Atmospheric Circulation and Summer Drought Variability of the Past Three Centuries, Boreal Canada
Download2006
Tardif, J.C., Girardin, M.P., Flannigan, M., Bergeron, Y.
Five independent multicentury reconstructions of the July Canadian Drought Code and one reconstruction of the mean July-August temperature were developed using a network of 120 well-replicated tree-ring chronologies covering the area of the eastern Boreal Plains to the eastern Boreal Shield of...

Temperature sensitivity of N2O emissions from fertilized agricultural soils: Mathematical modeling in ecosys
Download2008
N2O emissions have been found to be highly sensitive to soil temperature (T-s) which may cause substantial rises in emissions with rises in Ts expected in most climate change scenarios. Mathematical models used to project changes in emissions during climate change should be able to simulate the...

Temporal variability in area burned for the Province of Ontario, Canada during the past 200 years inferred from tree-rings
Download2006
Tardif, J., Flannigan, M.D., Girardin, M.P.
Area burned variability in the province of Ontario, Canada, was inferred from 25 tree ring width chronologies covering A. D. 1781-1982 and distributed largely across the Boreal Shield. The area burned estimates account for 39.5% of the variance in the actual area burned recorded from 1917 to 1981...
