Changes in net ecosystem productivity and greenhouse gas exchange with fertilization of Douglas fir: Mathematical modeling in ecosysDownload
Bruemmer, C., Jassal, R. S., Grant, R. F., Black, T. A.
Abstract: The application of nitrogen fertilizers to Douglas fir forests is known to raise net ecosystem productivity (NEP), but also N(2)O emissions, the CO(2) equivalent of which may offset gains in NEP when accounting for net greenhouse gas (GHG) exchange. However, total changes in NEP and...
Characterizing the performance of ecosystem models across time scales: A spectral analysis of the North American Carbon Program site-level synthesisDownload
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,...
Spittlehouse, D.L., Hamann, A., Murdock, T.Q., Wang, T.
This study addresses the need to provide comprehensive historical climate data and climate change projections at a scale suitable for, and readily accessible to, researchers and resource managers. This database for western North America (WNA) includes over 20 000 surfaces of monthly, seasonal,...
Comparison of boreal ecosystem model sensitivity to variability in climate and forest site parametersDownload
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,...
Nesbitt, H. W., MacRae, N. D., Shotyk, W.
Abstract: Polished (001) cleavage faces of Nain Labradorite (An almost-equal-to 56) were leached at 20-degrees-C (+/- 2-degrees) for 72 days in distilled water (pH almost-equal-to 5.6), in HCl solution (pH almost-equal-to 4.05) and in four other HCl solutions containing 1 mg/l or less of Na, K,...
Controls on carbon and energy exchange by a black spruce–moss ecosystem: Testing the mathematical model Ecosys with data from the BOREAS ExperimentDownload
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...
