Relationship Between Plant Hydraulic And Biochemical Properties Derived From A Steady-State Coupled Water And Carbon Transport Model
Katul, G., Leuning, R., Oren, R.

There is growing evidence that plant stomata have evolved physiological controls to satisfy the demand for CO2 by photosynthesis while regulating water losses by …

Partitioning Interannual Variability In Net Ecosystem Exchange Between Climatic Variability And Functional Change
Hui, D., Luo, Y., Katul, G.
Interannual variability (IAV) in net ecosystem exchange of carbon (NEE) is a critical factor in projections of future ecosystem changes. However, our understanding of IAV is limited because of the difficulty in isolating its numerous causes. We proposed that IAV in NEE is primarily caused by climatic variability, …

Novel Technique For Remote Estimation Of CO2 Flux In Maize
Gitelson, A. A., Verma, S. B., Rundquist, D. C., Keydan, G., Leavitt, B., Arkebauer, T. J., Burba, G. G., Suyker, A. E.

There is considerable interest in assessing the magnitude of carbon sources and sinks for agricultural lands, grasslands, and forests. In this paper, we propose a novel technique to remotely assess CO2 fluxes in maize using reflectances (ρ) in two spectral channels either in the green around 550 nm or in the red edge …

Interannual Variability In Net CO2 Exchange Of A Native Tallgrass Prairie
Suyker, A. E., Verma, S. B., Burba, G. G.

Year-round eddy covariance flux measurements were made in a native tallgrass prairie in north-central Oklahoma, USA during 1997–2000 to quantify carbon exchange and its interannual …

Post-Fire Carbon Dioxide Fluxes In The Western Canadian Boreal Forest: Evidence From Towers, Aircraft And Remote Sensing
Amiro, B. D., Ian MacPherson, J., Desjardins, R. L., Chen, J. M., Liu, J.

Recent CO2 flux measurements from towers and aircraft (net ecosystem exchange by eddy covariance) and remote sensing/modeling (net primary productivity—NPP) following fire show that the regenerating boreal forest in western Canada has a low initial flux that …

Diurnal And Seasonal Changes In Stem Increment And Water Use By Yellow Poplar Trees In Response To Environmental Stress
McLaughlin, S. B., Wullschleger, S. D., Nosal, M.
To evaluate indicators of whole-tree physiological responses to climate stress, we determined seasonal, daily and diurnal patterns of growth and water use in 10 yellow poplar (Liriodendron tulipifera L.) trees in a stand recently released from competition. Precise measurements of stem increment …

Modelling The Discrimination Of 13CO2 Above And Within A Temperate Broad-Leaved Forest Canopy On Hourly To Seasonal Time Scales
Baldocchi, D. D., Bowling, D. R.

Fluxes and concentrations of carbon dioxide and 13CO2 provide information about ecosystem physiological processes and their response to environmental …

Assessing Soil CO2 Efflux Using Continuous Measurements Of CO2 Profiles In Soils With Small Solid-State Sensors
Tang, J., Baldocchi, D. D., Qi, Y., Xu, L.

This paper describes a new method to monitor continuously soil CO2 profiles using small solid-state CO2 sensors buried at different depths of the soil. Based on the measurement of soil CO2 profile and a gaseous diffusivity model, we estimated …

Changes In Carbon Storage And Fluxes In A Chronosequence Of Ponderosa Pine
Law, B. E., Sun, O. J., Campbell, J., Van Tuyl, S., Thornton, P. E.

Forest development following stand-replacing disturbance influences a variety of ecosystem processes including carbon exchange with the atmosphere. On a series of ponderosa pine (Pinius ponderosa var. Laws.) stands ranging from 9 to> 300 years in central Oregon, USA, we used biological measurements to estimate carbon …
