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...

The effectiveness of two common sampling methods for assessing imperilled freshwater fishes
Download2007
Poos, M.S., Mandrak, N.E., McLaughlin, R.L.
This study tested the hypothesis that the most common gear type used to sample fishes in wadeable systems, electrofishing, was more effective than another commonly used gear type, seining, for sampling fish species at risk. Five predictions were tested. At sites where species at risk were...

The impact of phloem nutrients on overwintering mountain pine beetles and their fungal symbionts
Download2012
Erbilgin, N., Goodsman, D. W., Lieffers, V. J.
In the low nutrient environment of conifer bark, subcortical beetles often carry symbiotic fungi that concentrate nutrients in host tissues. Although bark beetles are known to benefit from these symbioses, whether this is because they survive better in nutrient-rich phloem is unknown. After...

Dale, M. R. T., MacDonald, S. E., Peters, V. S.
Abstract: We used the mast-seeding tree Picea glauca (white spruce) to examine whether the timing of mast years relative to fire had a lasting effect on the density and timing of regeneration. We studied 17 fires that occurred in mast years and in years with low cone production between 1941 and...
