Factors Controlling The Interannual Variability In The Carbon Balance Of A Southern Boreal Black Spruce Forest
Krishnan, P., Black, T. A., Barr, A. G., Grant, N. J., Gaumont-Guay, D., Nesic, Z.

Factors controlling the seasonal and interannual variability of net ecosystem
productivity (FNEP), gross ecosystem photosynthesis (Pg), ecosystem respiration (Re) and
evapotranspiration (E) of a mature boreal black spruce forest in central Saskatchewan,
Canada were investigated using eight years (1999–2006) of continuous eddy …

The Contribution Of Advective Fluxes To Net Ecosystem Exchange In A High-Elevation, Subalpine Forest
Yi, C., Anderson, D. E., Turnipseed, A. A., Burns, S. P., Sparks, J. P., Stannard, D. I., Monson, R. K.

The eddy covariance technique, which is used in the determination of net ecosystem CO2 exchange (NEE), is subject to significant errors when advection that carries CO2 in the mean flow is ignored. We measured horizontal and vertical advective CO2 fluxes at the Niwot Ridge AmeriFlux site (Colorado, USA) using a measurement approach …

Canopy Structure And Atmospheric Flows In Relation To The δ13c Of Respired Co2 In A Subalpine Coniferous Forest
Schaeffer, S. M., Anderson, D. E., Burns, S. P., Monson, R. K., Sun, J., Bowling, D. R.

Stable isotopes provide insight into ecosystem carbon cycling, plant physiological processes, atmospheric boundary-layer dynamics, and are useful for the integration of processes over multiple scales. Of particular interest is the carbon isotope content (δ13C) of nocturnal ecosystem-respired CO2 (δR). Recent advances in technology …

Partitioning Net Ecosystem Carbon Exchange And The Carbon Isotopic Disequilibrium In A Subalpine Forest
ZOBITZ, J. M., BURNS, S. P., REICHSTEIN, M., BOWLING, D. R.

We investigate the utility of an improved isotopic method to partition the net ecosystem exchange of CO2 (F) into net photosynthesis (FA) and nonfoliar respiration (FR). Measurements of F and the carbon isotopic content in air at a high‐elevation coniferous forest (the Niwot Ridge AmeriFlux site) were used to partition F into FA …

Multiyear Riparian Evapotranspiration And Groundwater Use For A Semiarid Watershed
Scott, R., Cable, W., Huxman, T., Nagler, P., Hernandez, M., Goodrich, D.

Riparian evapotranspiration (ET) is a major component of the surface and subsurface water balance for many semiarid watersheds. Measurement or model-based estimates of ET are often made on a local scale, but spatially distributed estimates are needed to determine ET over catchments. In this paper, we document the ET that was quantified …

Environmental And Biological Controls On Water And Energy Exchange In Florida Scrub Oak And Pine Flatwoods Ecosystems
Bracho, R., Powell, T. L., Dore, S., Li, J., Hinkle, C. R., Drake, B. G.

Scrub oak and pine flatwoods are two contrasting ecosystems common to the humid
subtropical climate of Florida. Scrub oak forests are short in stature (<2 m) and occur on
well-drained sandy soils, and pine flatwoods are much taller and occur in areas with
poorly drained soils. Eddy covariance measurements were made from January …

Hydrologic And Atmospheric Controls On Initiation Of Convective Precipitation Events
Juang, J., Porporato, A., Stoy, P. C., Siqueira, M. S., Oishi, A. C., Detto, M., Kim, H., Katul, G. G.

The pathway to summertime convective precipitation remains a vexing research problem because of the nonlinear feedback between soil moisture content and the atmosphere. Understanding this feedback is important to the southeastern U. S. region, given the high productivity of the timberland area and the role of summertime convective …
