Harrington, J.B., Flannigan, M.D.
Long dry spells (sequences of dry days) are rare events, but they are important because they correlate significantly with the area burned during bad wildfire years. Previous attempts to model the frequency of dry spells have been successful for spells of short duration, but have failed for...

Characterizing the performance of ecosystem models across time scales: A spectral analysis of the North American Carbon Program site-level synthesis
Download2011
Black, T.A., Izaurralde, R.C., Lokupitiya, E., Munger, J.W., Schaefer, K., Weng, E., Richardson, A.D., Altaf Arain, M., Luo, Y., Ciais, P., Ricciuto, D.M., Stoy, P.C., Dietze, M.C., Poulter, B., Barr, A.G., Liu, S., Hollinger, D., Tian, H., Suyker, A.E., Verbeeck, H., Price, D.T., Grant, R.F., Peng, C., Baker, I.T., Vargas, R., Anderson, R.S., Tonitto, C., Sahoo, A.K., Chen, J.M., Flanagan, L.B., Riley, W.J., Wang, W., Lafleur, P., Gough, C.M., Verma, S.B., Kucharik, C.J.
Ecosystem models are important tools for diagnosing the carbon cycle and projecting its behavior across space and time. Despite the fact that ecosystems respond to drivers at multiple time scales, most assessments of model performance do not discriminate different time scales. Spectral methods,...

Comparison of boreal ecosystem model sensitivity to variability in climate and forest site parameters
Download2001
McGuire, A.D., Chen, J.M., Liu, J., Frolking, S.E., Wang, S., Potter, C.S., Amthor, J.S., Nikolov, N.T., Clein, J.S., Kimball, J.S., King, A.W., Grant, R.F.
Ecosystem models are useful tools for evaluating environmental controls on carbon and water cycles under past or future conditions. In this paper we compare annual carbon and water fluxes from nine boreal spruce forest ecosystem models in a series of sensitivity simulations. For each comparison,...

Ecological controls on net ecosystem productivity of a mesic arctic tundra under current and future climates
Download2011
Dimitrov, D. D., Grant, R. F., Lafleur, P. M., Humphreys, E. R.
Abstract: Changes in arctic C stocks with climate are thought to be caused by rising net primary productivity (NPP) during longer and warmer growing seasons, offset by rising heterotrophic respiration (Rh) in warmer and deeper soil active layers. In this study, we used the process model ecosys to...

This literature review provides an understanding of ecological resilience as a concept to promote successful land reclamation in Alberta’s mineable oil sands region by exploring four key issues: Defining ecological resilience for boreal forest ecosystems, and assessing whether this definition can...

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...

Monitoring Procedures for Wellsite, In-Situ Oil Sands and Coal Mine Reclamation in Alberta (MOPRA) – December 2014 Update
Download2014-05-22
Yang, X., Doherty, R., Staenz, K., Zhang, J., Rolfson, D., Rochdi, N., King, C., Banting, J.
The scope of the Monitoring Procedure for Reclamation in Alberta (MOPRA) project is to develop a geomatics-based monitoring system to support the Government of Alberta’s efforts for monitoring reclamation success. This software will support the decision making process to screen almost all oil...

Oil Sands Terrestrial Habitat and Risk Modelling for Disturbance and Reclamation: The Impact of Climate Change on Tree Regeneration and Productivity – Phase III Report
Download2013-06-27
The overall objective of this project is to develop a framework that integrates risk management and strategic decision-making to evaluate the impact of disturbance (natural and industrial) on ecosystem products and services, and on habitat availability for terrestrial species in Alberta’s Lower...
