Influence Of Stand Age On The Magnitude And Seasonality Of Carbon Fluxes In Canadian Forests
Coursolle, C., Margolis, H., Giasson, M., Bernier, P., Amiro, B., Arain, M., Barr, A., Black, T., Goulden, M., McCaughey, J., Chen, J., Dunn, A., Grant, R., Lafleur, P.

Proper management and accounting of forest carbon requires good knowledge of how disturbances and climate affect the carbon dynamics of different stand types. We have investigated such relationships by measuring, over a 5-year period (2003–2007), the net ecosystem productivity (NEP), gross ecosystem productivity …

Creating Wetlands: Primary Succession, Water Quality Changes, And Self-Design Over 15 Years
Mitsch, W. J., Zhang, L., Stefanik, K. C., Nahlik, A. M., Anderson, C. J., Bernal, B., Hernandez, M., Song, K.
The succession of vegetation, soil development, water quality changes, and carbon and nitrogen dynamics are summarized in this article for a pair of 1-hectare flow-through-created riverine wetlands for their first 15 years. Wetland plant richness increased from 13 originally planted species to 116 species …

On The Choice Of The Driving Temperature For Eddy-Covariance Carbon Dioxide Flux Partitioning

Old-Growth CO2 Flux Measurements Reveal High Sensitivity To Climate Anomalies Across Seasonal, Annual And Decadal Time Scales
Wharton, S., Falk, M., Bible, K., Schroeder, M., Paw U, K.T.

The traditional hypothesis that old-growth forests are carbon neutral is under debate as recent studies
show evidence of net carbon sequestration. Here, we present a decade (1998–2008) of carbon dioxide,
water and energy fluxes from an old-growth stand in the American Pacific Northwest to identify
ecosystem-level responses to …

Greenhouse Gas (CO2, CH4, H2O) Fluxes From Drained And Flooded Agricultural Peatlands In The Sacramento-San Joaquin Delta
Hatala, J. A., Detto, M., Sonnentag, O., Deverel, S. J., Verfaillie, J., Baldocchi, D. D.

The Sacramento-San Joaquin Delta in California was drained and converted to agriculture more than a century ago, and since then has experienced extreme rates of soil subsidence from peat oxidation. To reverse subsidence and capture carbon there is increasing interest in converting drained agricultural land-use types …

Increased CO2 Loss From Vegetated Drained Lake Tundra Ecosystems Due To Flooding
Zona, D., Lipson, D. A., Paw U, K. T., Oberbauer, S. F., Olivas, P., Gioli, B., Oechel, W. C.

Tundra ecosystems are especially sensitive to climate change, which is particularly rapid in high northern latitudes resulting in significant alterations in temperature and soil moisture. Numerous studies have demonstrated that soil drying increases the respiration loss from wet Arctic tundra. And, warming and drying of tundra soils …

The Role Of Harvest Residue In Rotation Cycle Carbon Balance In Loblolly Pine Plantations. Respiration Partitioning Approach
Noormets, A., McNulty, S. G., Domec, J., Gavazzi, M., Sun, G., King, J. S.

Timber harvests remove a significant portion of ecosystem carbon. While some of the wood products moved off-site may last past the harvest cycle of the particular forest crop, the effect of the episodic disturbances …

State-Dependent Errors In A Land Surface Model Across Biomes Inferred From Eddy Covariance Observations On Multiple Timescales

Interactive Effects Of Nocturnal Transpiration And Climate Change On The Root Hydraulic Redistribution And Carbon And Water Budgets Of Southern United States Pine Plantations
Domec, J., Ogee, J., Noormets, A., Jouangy, J., Gavazzi, M., Treasure, E., Sun, G., McNulty, S. G., King, J. S.

Deep root water uptake and hydraulic redistribution (HR) have been shown to play a major role in forest ecosystems during drought, but little is known about the impact of climate change, fertilization and soil characteristics on HR and its consequences on water and carbon fluxes. Using data from three mid-rotation loblolly pine plantations, …
