Age-Dependent Changes In Ecosystem Carbon Fluxes In Managed Forests In Northern Wisconsin, USA
Noormets, A., Chen, J., Crow, T. R.

The age-dependent variability of ecosystem carbon (C) fluxes was assessed by measuring the net ecosystem exchange of C (NEE) in five managed forest stands in northern Wisconsin, USA. The study sites ranged in age from 3-year-old clearcut to mature stands (65 years). All stands, except the clearcut, …

Concentrations And Fluxes Of Dissolved Organic Carbon In An Age-Sequence Of White Pine Forests In Southern Ontario, Canada
Peichl, M., Moore, T. R., Arain, M. A., Dalva, M., Brodkey, D., McLaren, J.

We determined concentrations and fluxes of dissolved organic carbon (DOC) in precipitation, throughfall, forest floor and mineral soil leachates from June 2004 to May 2006 across an age-sequence (2-, 15-, 30-, and 65-year-old) of white pine (Pinus strobus L.) forests in southern Ontario, Canada. …

Use Of Digital Webcam Images To Track Spring Green-Up In A Deciduous Broadleaf Forest
Richardson, A. D., Jenkins, J. P., Braswell, B. H., Hollinger, D. Y., Ollinger, S. V., Smith, M.

Understanding relationships between canopy structure and the seasonal dynamics of photosynthetic uptake of CO2 by forest canopies requires improved knowledge of canopy phenology at eddy covariance flux tower sites. We investigated whether digital …

Comparison Of Carbon Dioxide Fluxes Over Three Boreal Black Spruce Forests In Canada
Bergeron, O., Margolis, H. A., Black, T. A., Coursolle, C., Dunn, A. L., Barr, A. G., Wofsy, S. C.

Although mature black spruce forests are a dominant cover type in the boreal forest of North America, it is not clear how their carbon (C) budgets vary across the continent. …

Remotely Sensed Measurements Of Forest Structure And Fuel Loads In The Pinelands Of New Jersey
SKOWRONSKI, N., CLARK, K., NELSON, R., HOM, J., PATTERSON, M.

We used a single-beam, first return profiling LIDAR (Light Detection and Ranging) measurements of canopy height, intensive biometric measurements in plots, and Forest Inventory and Analysis (FIA) data to quantify forest structure and ladder fuels (defined as vertical fuel continuity between the understory and canopy) in the New Jersey …

Spatiotemporal Variations In Growing Season Exchanges Of Co2, H2o, And Sensible Heat In Agricultural Fields Of The Southern Great Plains
Fischer, M. L., Billesbach, D. P., Berry, J. A., Riley, W. J., Torn, M. S.

Climate, vegetation cover, and management create finescale heterogeneity in unirrigated agricultural regions, with important but not well-quantified consequences for spatial and temporal variations in surface CO2, water, and heat fluxes. Eddy covariance fluxes were measured in seven agricultural fields—comprising winter wheat, …

Co2 Transport Over Complex Terrain
Sun, J., Burns, S. P., Delany, A. C., Oncley, S. P., Turnipseed, A. A., Stephens, B. B., Lenschow, D. H., LeMone, M. A., Monson, R. K., Anderson, D. E.

CO2 transport processes relevant for estimating net ecosystem exchange (NEE) at the Niwot Ridge AmeriFlux site in the front range of the Rocky Mountains, Colorado, USA, were investigated during a pilot experiment. We found that cold, moist, and CO2-rich air was transported downslope at night and upslope in the early morning at this …

Partitioning Net Ecosystem Exchange Of Co2: A Comparison Of A Bayesian/Isotope Approach To Environmental Regression Methods
Zobitz, J. M., Burns, S. P., Ogée, J., Reichstein, M., Bowling, D. R.

Separation of the net ecosystem exchange of CO2 (F) into its component fluxes of net photosynthesis (FA) and nonfoliar respiration (FR) is important in understanding the physical and environmental controls on these fluxes, and how these fluxes may respond to environmental change. In this paper, we evaluate a partitioning method based …
