Modeling the effects of hydrology on gross primary productivity and net ecosystem productivity at Mer Bleue bog
Download2011
Humphreys, E., Dimitrov, D. D., Grant, R. F., LaFleur, P. M.
Abstract: The ecosys model was applied to investigate the effects of water table and subsurface hydrology changes on carbon dioxide exchange at the ombrotrophic Mer Bleue peatland, Ontario, Canada. It was hypothesized that (1) water table drawdown would not affect vascular canopy water potential,...

Desai, A., Grant, R.F., Sulman, B.
Responses of wetland productivity to changes in water table depth (WTD) are controlled by complex interactions among several soil and plant processes, and hence are site-specific rather than general in nature. Hydrological controls on wetland productivity were studied by representing these...

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...

Nitrous Oxide Fluxes in Permafrost Peatlands remain negligible after Wildfire and Thermokarst Disturbance
Nitrous Oxide Fluxes in Permafrost Peatlands remain negligible after Wildfire and Thermokarst Disturbance
Download2022-11-29
The greenhouse gas (GHG) balance of boreal peatlands in permafrost regions will be affected by climate change through disturbances such as permafrost thaw and wildfire. Although the future GHG balance of boreal peatlands including ponds is dominated by the exchange of both carbon dioxide (CO2)...

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...
