Photosynthesis And Light-Use Efficiency By Plants In A Canadian Boreal Forest Ecosystem
Whitehead, D., Gower, S. T.
Measurements of the photosynthetic response to midsummer irradiance were made for 11 species representing the dominant trees, understory shrubs, herbaceous plants and moss species in an old black spruce (Picea mariana (Mill.) B.S.P.) boreal forest ecosystem. Maximum rates of photosynthesis per unit …

Response Of Stomatal Conductance To Drought In Ponderosa Pine: Implications For Carbon And Ozone Uptake
Panek, J. A., Goldstein, A. H.
To gain insight into the limitations imposed by a typical Mediterranean-climate summer drought on the uptake of carbon and ozone in the ponderosa pine (Pinus ponderosa Dougl. ex Laws.) ecosystem, we compared diurnal trends in leaf physiology of young trees in a watered and a control plot …

Quantifying The Complexity In Mapping Energy Inputs And Hydrologic State Variables Into Land-Surface Fluxes
Katul, G. G., Lai, C., Albertson, J. D., Vidakovic, B., Schäfer, K. V., Hsieh, C., Oren, R.

This study explores the complexity (or disorder) in mapping energy (Rn) forcing to land surface fluxes of sensible heat (Hs), water vapor (LE), and carbon dioxide (or net ecosystem exchange, NEE) for different soil water states (θ). Specifically, we ask, does the vegetation …

Annual Cycle Of CO2 Exchange At A Bog Peatland
Lafleur, P. M., Roulet, N. T., Admiral, S. W.

Eddy covariance measurements of the carbon dioxide flux from an ombrotrophic bog near Ottawa, Canada, were made between June 1, 1998, and May 31, 1999. Net ecosystem exchange of CO2 (NEE) showed …

Leaf Age Affects The Seasonal Pattern Of Photosynthetic Capacityand Net Ecosystem Exchange Of Carbon In A Deciduous Forest
Wilson, K. B., Baldocchi, D. D., Hanson, P. J.

Temporal trends in photosynthetic capacity are a critical factorin determining the seasonality and magnitude of ecosystem carbonfluxes. At a mixed deciduous forest in the south-eastern United States (Walker Branch Watershed, Oak Ridge, TN, USA), we independently measured seasonal trends in photosynthetic capacity (using single-leaf …

Comparing Independent Estimates Of Carbon Dioxide Exchange Over 5 Years At A Deciduous Forest In The Southeastern United States
Wilson, K. B., Baldocchi, D. D.

At a deciduous forest in the southeast United States (Walker Branch Watershed, Oak Ridge, Tennessee), as at other sites with tall vegetation and/or complex terrain, it is difficult to temporally integrate …

Fluxes of oxygenated volatile organic compounds from a ponderosa pine plantatio
Schade,G.W., Goldstein,A.H.

We present the first canopy-scale, continuous, long-term flux measurements of a suite of oxygenated volatile organic compounds (OVOCs). Fluxes were measured above a ponderosa pine plantation, adjacent to the Blodgett Forest Research Station (38°53′42.9″N, 120°37′57.9″W, 1315 m elevation), with a fully automated relaxed …

Aerosol Properties At A Midlatitude Northern Hemisphere Continental Site
Koloutsou-Vakakis, S., Carrico, C. M., Kus, P., Rood, M. J., Li, Z., Shrestha, R., Ogren, J. A., Chow, J. C., Watson, J. G.

Measurements of chemical, physical, and optical properties of ambient aerosol particles were obtained at Bondville, Illinois. This research was completed to increase the spatial and temporal resolution of measured aerosol. Results from measurements describe (1) the physical and chemical characteristics of the aerosol and (2) the …

Factors Controlling Long- And Short-Term Sequestration Of Atmospheric CO2 In A Mid-Latitude Forest
Barford, C. C., Wofsy, S. C., Goulden, M. L., Munger, J. W., Pyle, E. H., Urbanski, S. P., Hutyra, L., Saleska, S. R., Fitzjarrald, D., Moore, K.

Net uptake of carbon dioxide (CO2) measured by eddy covariance in a 60- to 80-year-old forest averaged 2.0 ± 0.4 megagrams of carbon per hectare per year during 1993 to 2000, with interannual variations exceeding 50%. Biometry indicated storage of 1.6 ± 0.4 megagrams of carbon per hectare per year over 8 years, 60% in …
