Partitioning Of Evapotranspiration And Its Relation To Carbon Dioxide Exchange In A Chihuahuan Desert Shrubland
Scott, R. L., Huxman, T. E., Cable, W. L., Emmerich, W. E.

Key to evaluating the consequences of woody plant encroachment on water and carbon cycling in semiarid ecosystems is a mechanistic understanding of how biological and non-biological processes influence water loss to the atmosphere. To better understand how precipitation is partitioned into the components of evapotranspiration (bare-soil …

A Distinct Seasonal Pattern Of The Ratio Of Soil Respiration To Total Ecosystem Respiration In A Spruce-Dominated Forest
Davidson, E. A., Richardson, A. D., Savage, K. E., Hollinger, D. Y.

Annual budgets and fitted temperature response curves for soil respiration and ecosystem respiration provide useful information for partitioning annual carbon budgets of ecosystems, …

Carbon, Energy And Water Fluxes At Mature And Disturbed Forest Sites, Saskatchewan, Canada
Amiro, B., Barr, A., Black, T., Iwashita, H., Kljun, N., Mccaughey, J., Morgenstern, K., Murayama, S., Nesic, Z., Orchansky, A.

Fire and harvesting are important disturbances in the boreal forest, driving net biome production. Measurements of net ecosystem production (NEP) over mature forest stands have been made from flux towers for about a decade at the Boreal Ecosystem Research and Monitoring Sites (BERMS) in central Saskatchewan, Canada. Over the last …

Combining Meteorology, Eddy Fluxes, Isotope Measurements, And Modeling To Understand Environmental Controls Of Carbon Isotope Discrimination At The Canopy Scale
Aranibar, J. N., Berry, J. A., Riley, W. J., Pataki, D. E., Law, B. E., Ehleringer, J. R.

Estimates of terrestrial carbon isotope discrimination are useful to quantify the terrestrial carbon sink. Carbon isotope discrimination by terrestrial ecosystems may vary on seasonal and interannual time frames, because it is affected by processes (e.g. photosynthesis, stomatal conductance, and respiration) that respond to variable …

Environmental Control Of Net Ecosystem Co2 Exchange In A Treed, Moderately Rich Fen In Northern Alberta
Syed, K. H., Flanagan, L. B., Carlson, P. J., Glenn, A. J., Van Gaalen, K. E.

Peatlands cover about 21% of the landscape and contain about 80% of the soil carbon stock in western Canada. However, the current rates of carbon accumulation and the environmental controls on ecosystem photosynthesis and respiration in peatland ecosystems are poorly understood. …

Environmental Controls Over Net Ecosystem Carbon Exchange Of Scrub Oak In Central Florida
Powell, T. L., Bracho, R., Li, J., Dore, S., Hinkle, C. R., Drake, B. G.

Biological and physical controls regulating variation of seasonal and interannual ecosystem carbon exchange in a scrub oak ecosystem in central Florida were determined by measuring net ecosystem exchange of CO2 (NEE) between the atmosphere and vegetation using …

An Evaluation Of Models For Partitioning Eddy Covariance-Measured Net Ecosystem Exchange Into Photosynthesis And Respiration
Stoy, P. C., Katul, G. G., Siqueira, M. B., Juang, J., Novick, K. A., Uebelherr, J. M., Oren, R.

We measured net ecosystem CO2 exchange (NEE) using the eddy covariance (EC) technique for 4 years at adjoining old field (OF), planted pine (PP) and hardwood forest (HW) ecosystems in the Duke Forest, NC. To compute annual sums of NEE and its components – gross …

Estimating The Uncertainty In Annual Net Ecosystem Carbon Exchange: Spatial Variation In Turbulent Fluxes And Sampling Errors In Eddy-Covariance Measurements
Oren, R., Hsieh, C., Stoy, P., Albertson, J., Mccarthy, H. R., Harrell, P., Katul, G. G.

Above forest canopies, eddy covariance (EC) measurements of mass (CO2, H2O vapor) and energy exchange, assumed to represent ecosystem fluxes, are commonly …

Modeling Evapotranspiration In Arctic Coastal Plain Ecosystems Using A Modified BIOME-BGC Model
Engstrom, R., Hope, A., Kwon, H., Harazono, Y., Mano, M., Oechel, W.

Modeling evapotranspiration (ET) in Arctic coastal plain ecosystems is challenging owing to the unique conditions present in this environment, including permafrost, nonvascular vegetation, and a large standing dead vegetation component. In this study the ecosystem process model, BIOME-BGC, was adapted to represent these unique conditions …

Above- And Belowground Ecosystem Biomass And Carbon Pools In An Age-Sequence Of Temperate Pine Plantation Forests
Peichl, M., Arain, M. A.

We assessed the successional development of above- and belowground ecosystem biomass and carbon (C) pools in an age-sequence of four White pine (Pinus strobus L.) plantation stands (2-, 15-, 30-, and 65-years-old) in Southern Ontario, Canada. Biomass and C stocks of above- and belowground live and dead tree biomass, understorey …
