Changes In Vegetation Condition And Surface Fluxes During NAME 2004
Watts, C. J., Scott, R. L., Garatuza-Payan, J., Rodriguez, J. C., Prueger, J. H., Kustas, W. P., Douglas, M.

The vegetation in the core region of the North American monsoon (NAM) system changes dramatically after the onset of the summer rains so that large changes may be expected in the surface fluxes of radiation, heat, and moisture. Most of this region lies in the rugged terrain of western Mexico and very few measurements of these fluxes …

Allometry And Partitioning Of Above- And Belowground Tree Biomass In An Age-Sequence Of White Pine Forests
Peichl, M., Arain, M. A.

The allometry and partitioning of above- and belowground tree biomass was studied in an age-sequence of four eastern white pine (Pinus strobus L.) forests (2-, 15-, 30-, and 65-year-old) in southern Ontario, Canada. Biomass in each tree component, i.e. foliage, …

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, …
