Boreal forest CO2 exchange and evapotranspiration predicted by nine ecosystem process models: Inter-model comparisons and relationships to field measurements
Download2001
Wofsy, S.C., Frolking, S.E., Wang, S., Clein, J.S., McGuire, A.D., Potter, C.S., Goulden, M.L., Chen, J.M., Grant, R.F., Nikolov, N.T., Amthor, J.S., Kimball, J.S., King, A.W.
Nine ecosystem process models were used to predict CO2 and water vapor exchanges by a 150-year-old black spruce forest in central Canada during 1994-1996 to evaluate and improve the models. Three models had hourly time steps, five had daily time steps, and one had monthly time steps. Model input...

Comparison of boreal ecosystem model sensitivity to variability in climate and forest site parameters

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,...

Knapp, A. K., Collins, S. L., Turkington, R. , Long, R., White, S., Cahill, J. F., Carlyle, C. N., Beierkuhnlein, C., Luo, Y., Casper, B. B. Cleland, E., Lind, E., Smith, M. D., Henry, H. A. L., Dukes, J. S., Fraser, L. H., Reich, P. B., Sternberg, M.
There is a growing realization among scientists and policy makers that an increased understanding of today's environmental issues requires international collaboration and data synthesis. Meta-analyses have served this role in ecology for more than a decade, but the different experimental...

Detailed GIS studies across spatially complex rangeland landscapes, including the Aspen Parkland of western Canada, require accurate digital elevation models (DEM). Following the interpolation of last return lidar (light detection and ranging) data into a DEM, a series of 256 reference plots,...

Mathematical modeling of nitrous oxide emissions from an agricultural field during spring thaw
Download1999
Confidence in regional estimates of N2O emissions used in national greenhouse gas inventories could be improved by using mathematical models of the biological and physical processes by which these emissions are known to be controlled. However these models must first be rigorously tested against...

Native prairie communities have evolved to produce relatively low but sustained production. Demand for greater production has resulted in overgrazing and, consequently, lower and more unstable annual yields and increased risk of soil erosion. Because the Rough Fescue Prairie is best suited for...
