Aspen (Populus tremuloides) root suckering as influenced by log storage, traffic-induced-root wounding, slash accumulation, and soil compaction
DownloadFall 2009
The objective of this thesis was to determine how aspen (Populus tremuloides Michx.) root systems and suckering are affected by decking area (site of log processing and storage) disturbances and seasonal timing of these disturbances. In a field study, summer-built log decks reduced regeneration...

Carbon and energy exchange by a black spruce – moss ecosystem under changing climate: testing the mathematical model ecosys with data from the BOREAS experiment
Download2001
Grant, R.F., Berry, J.A., Wofsy, S.C., Goulden, M.L.
There is some uncertainty whether net ecosystem productivity (NEP) of boreal black spruce forests is positive or negative under current climates and how NEP would change under hypothesized changes in future climates. The mathematical model ecosys was used to examine NEP of a boreal black spruce...

Controls on carbon and energy exchange by a black spruce–moss ecosystem: Testing the mathematical model Ecosys with data from the BOREAS Experiment

Massheder, J.M., Berry, J.A., Scott, S.L., Rayment, M., Jarvis, P.G., Grant, R.F., Hale, S.E., Moncrieff, J.B.
Stomatal limitations to mass and energy exchange over boreal black spruce forests may be caused by low needle N concentrations that limit CO(2) fixation rates. These low concentrations may be caused by low N uptake rates from cold boreal soils with high soil C:N ratios and by low N deposition...

Effects of recreational traffic on alpine plant communities in the northern Canadian Rockies
Download2012
MacDonald, S. E., Crisfield, V., Gould, J.
Abstract: Recreational activities in alpine areas have been increasing in recent decades, creating the need to improve our understanding of the impacts of these activities and how they are best managed. We explored impacts of recreational trail use on dry alpine meadows in the northern Canadian...

Forest floor protection during drilling pad construction and its benefits for natural regeneration of native boreal forest vegetation
DownloadSpring 2014
I tested forest floor protection techniques in the construction and reclamation of temporary drilling pads to restore native boreal canopy and understory cover. By covering and delineating the forest floor I hoped to reduce damage to the vegetative propagule bank, so clonal species such as aspen...
