Net ecosystem productivity of temperate and boreal forests after clearcutting - a Fluxnet-Canada measurement and modelling synthesis
Download2010
Barr, A. G., Trofymow, J. A., McCaughey, J. H., Black, T. A., Margolis, H. A., Grant, R. F.
Abstract: Clearcutting strongly affects subsequent forest net ecosystem productivity (NEP). Hypotheses for ecological controls on NEP in the ecosystem model ecosys were tested with CO(2) fluxes measured by eddy covariance (EC) in three post-clearcut conifer chronosequences in different ecological...

Nobody’s perfect: Can irregularities in pit structure influence vulnerability to cavitation?
Download2013
Plavcová, Lenka, Hacke, Uwe G., Klepsch, Matthias M., Jansen, Steven
Recent studies have suggested that species-specific pit properties such as pit membrane thickness, pit membrane porosity, torus-to-aperture diameter ratio and pit chamber depth influence xylem vulnerability to cavitation. Despite the indisputable importance of using mean pit characteristics,...

Nutritional Significance of Wapiti (Cervus elaphus) Migrations to Alpine Ranges in Western Alberta, Canada
Download1989
Morgantini, L.E., Hudson, R.J.
This study was designed to provide a better understanding of the nutritional significance of wapiti (Cervus elaphus) migrations from low-elevation winter ranges onto high-elevation alpine summer ranges. The study focused on a population along the east slopes of the Rocky Mountains in western...

Oak forest carbon and water simulations: model intercomparisons and evaluations against independent data
Download2004
Baldocchi, D.D., Luo, Y., Grant, R.F., Hui, D., Amthor, J.S., Sun, G., Wullschleger, S.D., King, A.W., Johnson, D.W., Hanson, P.J., Williams, M., Thornton, P.E., Hartley, A., Kimball, J.S., Cushman, R.M., Hunt Jr., E.R., McNulty, S.G., Wang, S., Wilson, K.B.
Models represent our primary method for integration of small-scale, process-level phenomena into a comprehensive description of forest-stand or ecosystem function. They also represent a key method for testing hypotheses about the response of forest ecosystems to multiple changing environmental...

Optimal forest harvest age considering carbon sequestration in multiple carbon pools: A comparative statics analysis
Download2012
Armstrong, Glen W, Asante, Patrick
We present an analytical model for determination of the economically optimal harvest age of a forest stand considering timber value, and the value of carbon fluxes in living biomass, dead organic matter, and wood products pools. Through comparative statics analysis, we find that consideration of...

Luckert, Martin K., Armstrong, Glen W., Adamowicz, Wiktor L., Anderson, Jay A.
Previous studies suggest that management intensity zoning systems, such as the triad approach, could allow Canada’s forest industry to maintain or increase timber harvest levels while simultaneously reducing its environmental impact. In most such studies, the zones are exogenously specified. In...

Ma, K. P., Yu, M. J., Sun, I. F., Legendre, P., Mi, X. C., He, F. L., Ren, H. B.
Abstract: The classical environmental control model assumes that species distribution is determined by the spatial variation of underlying habitat conditions. This niche-based model has recently been challenged by the neutral theory of biodiversity which assumes that ecological drift is a key...
