Cross Validation Of Open-Top Chamber And Eddy Covariance Measurements Of Ecosystem CO2 Exchange In A Florida Scrub-Oak Ecosystem
Dore, S., Hymus, G. J., Johnson, D. P., Hinkle, C. R., Valentini, R., Drake, B. G.

Simultaneous measurements of net ecosystem CO2 exchange (NEE) were made in a Florida scrub-oak ecosystem in August 1997 and then every month between April 2000 to …

Partitioning Of Water Flux In A Sierra Nevada Ponderosa Pine Plantation
Kurpius, M., Panek, J., Nikolov, N., McKay, M., Goldstein, A.

The weather patterns of the west side of the Sierra Nevada Mountains (cold, wet winters and hot, dry summers) strongly influence how water is partitioned between transpiration and evaporation and result in a specific strategy of water use by ponderosa pine trees (Pinus …

Species Differences In Stomatal Control Of Water Loss At The Canopy Scale In A Mature Bottomland Deciduous Forest
Pataki, D., Oren, R.

In order to evaluate factors controlling transpiration of six common eastern deciduous species in North America, a model describing responses of canopy stomatal conductance (GS) to net radiation (RN), vapor pressure deficit (D) and relative extractable soil water (REW) was parameterized …

Gas-Phase Chemistry Dominates O3 Loss To A Forest, Implying A Source Of Aerosols And Hydroxyl Radicals To The Atmosphere
Kurpius, M. R., Goldstein, A. H.

Tropospheric ozone (O3) effectively deposits to forested ecosystems but the fate of O3 within the forest canopy is unresolved. We partitioned total measured ecosystem daytime O3 deposition to a ponderosa pine (Pinus ponderosa) forest into its major loss pathways; stomatal uptake, non-stomatal …

Contribution Of Soil Respiration In Tropical, Temperate, And Boreal Forests To The O18 Enrichment Of Atmospheric O2
Angert, A., Barkan, E., Barnett, B., Brugnoli, E., Davidson, E. A., Fessenden, J., Maneepong, S., Panapitukkul, N., Randerson, J. T., Savage, K., Yakir, D., Luz, B.

The 18O content of atmospheric O2 is an important tracer for past changes in the biosphere. Its quantitative use depends on knowledge of the discrimination against 18O associated with the various Oconsumption processes. Here we evaluated, for the first time, the in situ 18O …

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 …

A Cross-Biome Comparison Of Daily Light Use Efficiency For Gross Primary Production
Turner, D. P., Urbanski, S., Bremer, D., Wofsy, S. C., Meyers, T., Gower, S. T., Gregory, M.

Vegetation light use efficiency is a key physiological parameter at the canopy scale, and at the daily time step is a component of remote sensing algorithms for scaling gross …

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 …
