Hydraulic Redistribution Of Soil Water By Roots Affects Whole-Stand Evapotranspiration And Net Ecosystem Carbon Exchange
Domec, J., King, J. S., Noormets, A., Treasure, E., Gavazzi, M. J., Sun, G., McNulty, S. G.
  • Hydraulic redistribution (HR) of water via roots from moist to drier portions of the soil occurs in many ecosystems, potentially influencing both water use and carbon assimilation.
  • By measuring soil water content, sap flow and eddy covariance, we investigated the temporal variability of …

Plant Community, Primary Productivity, And Environmental Conditions Following Wetland Re-Establishment In The Sacramento-San Joaquin Delta, California
Miller, R. L., Fujii, R.

Wetland restoration can mitigate aerobic decomposition of subsided organic soils, as well as re-establish conditions favorable for carbon storage. Rates of carbon storage result from the balance of inputs and losses, both of which are affected by wetland …

Using Watershed Water Balance To Evaluate The Accuracy Of Eddy Covariance Evaporation Measurements For Three Semiarid Ecosystems
Scott, R. L.

The eddy covariance technique is a widely used and accepted method to quantify ecosystem-scale mass and energy fluxes. Eddy covariance measurements of evaporation, also known as evapotranspiration, are used to determine local, regional and global water budgets, calibrate …

Relative Contributions Of Soil, Foliar, And Woody Tissue Respiration To Total Ecosystem Respiration In Four Pine Forests Of Different Ages
Khomik, M., Arain, A.M., Brodeur, J.J., Peichl, M., Restrepo-Coupé, N., McLaren, J.D.

Carbon dioxide (CO2) emissions from soil, foliage, and live woody tissue were measured throughout the year in afforested, white pine (Pinus strobus L.) stands (67, 32, 17, and 4 years old as of 2006), growing in a northern temperate climate. The data were used to estimate annual ecosystem respiration (Re) …

Ecosystem Carbon Dioxide Fluxes After Disturbance In Forests Of North America
Amiro, B. D., Barr, A. G., Barr, J. G., Black, T. A., Bracho, R., Brown, M., Chen, J., Clark, K. L., Davis, K. J., Desai, A. R., Dore, S., Engel, V., Fuentes, J. D., Goldstein, A. H., Goulden, M. L., Kolb, T. E., Lavigne, M. B., Law, B. E., Margolis, H. A., Martin, T., McCaughey, J. H., Misson, L., Montes-Helu, M., Noormets, A., Randerson, J. T., Starr, G., Xiao, J.

Disturbances are important for renewal of North American forests. Here we summarize more than 180 site years of eddy covariance measurements of carbon dioxide flux made at forest chronosequences in North America. The disturbances included stand-replacing fire (Alaska, Arizona, Manitoba, and Saskatchewan) and harvest (British Columbia, …

On The Correct Estimation Of Effective Leaf Area Index: Does It Reveal Information On Clumping Effects?
Ryu, Y., Nilson, T., Kobayashi, H., Sonnentag, O., Law, B. E., Baldocchi, D. D.

Effective leaf area index is routinely quantified with optical instruments that measure gap fraction through the probability of beam penetration of sunlight through the vegetation. However, there have been few efforts to obtain theoretically consistent effective leaf area …

Uncertainty Estimates For 1-H Averaged Turbulence Fluxes Of Carbon Dioxide, Latent Heat And Sensible Heat
Vickers, D., Göckede, M., Law, B.

A new observational approach is presented to approximate the uncertainty (scatter or error variance) in 1-h averaged turbulence fluxes …

Response Of Carbon Fluxes To Drought In A Coastal Plain Loblolly Pine Forest
Noormets, A., Gavazzi, M. J., Mcnulty, S. G., Domec, J., Sun, G., King, J. S., Chen, J.

Full accounting of ecosystem carbon (C) pools and fluxes in coastal plain ecosystems remains less studied compared with upland systems, even though the C stocks in these systems …

On The Differential Advantages Of Evergreenness And Deciduousness In Mediterranean Oak Woodlands: A Flux Perspective
Baldocchi, D. D., Ma, S., Rambal, S., Misson, L., Ourcival, J., Limousin, J., Pereira, J., Papale, D.

We assessed the differential advantages of deciduousness and evergreenness by examining 26 site-years of carbon dioxide, water vapor, and energy flux measurements from five comparable oak woodlands in France, Italy, Portugal, and California (USA). On average, the evergreen and deciduous oak woodlands assimilated and respired similar …
