Energy Exchange Across A Chronosequence Of Slash Pine Forests In Florida
Gholz, H. L., Clark, K. L.

We measured net atmospheric exchanges of energy and water vapor using eddy covariance along a chronosequence of Pinus elliottii plantations in north Florida: a recent clear-cut, a mid-rotation stand, and a 24-year-old, rotation-aged stand. Reflected energy averaged 0.26 of incoming solar radiation at the clear-cut and 0.18 …

Belowground Carbon Allocation In Forests Estimated From Litterfall And IRGA-Based Soil Respiration Measurements
Davidson, E., Savage, K., Bolstad, P., Clark, D., Curtis, P., Ellsworth, D., Hanson, P., Law, B., Luo, Y., Pregitzer, K., Randolph, J., Zak, D.

Allocation of C to belowground plant structures is one of the most important, yet least well quantified fluxes of C in terrestrial ecosystems. In a literature review of mature forests worldwide, Raich …

Acclimation Of Photosynthesis And Respiration To Elevated Atmospheric CO2 In Two Scrub Oaks
Hymus, G. J., Snead, T. G., Johnson, D. P., Hungate, B. A., Drake, B. G.

For two species of oak, we determined whether increasing atmospheric CO2 concentration (Ca) would decrease leaf mitochondrial respiration (R) directly, or indirectly owing to their growth in elevated Ca, or both. In particular, we tested whether acclimatory decreases in leaf-Rubisco …

Elevated Atmospheric CO2 Stimulates Aboveground Biomass In A Fire-Regenerated Scrub-Oak Ecosystem
Dijkstra, P., Hymus, G., Colavito, D., Vieglais, D. A., Cundari, C. M., Johnson, D. P., Hungate, B. A., Hinkle, C. R., Drake, B. G.

The effect of elevated atmospheric CO2 concentration (Ca) on the aboveground biomass of three oak species, Quercus myrtifolia, Q. …

Estimation Of Tropical Forest Structural Characteristics Using Large-Footprint Lidar
Drake, J. B., Dubayah, R. O., Clark, D. B., Knox, R. G., Blair, J., Hofton, M. A., Chazdon, R. L., Weishampel, J. F., Prince, S.

Quantification of forest structure is important for developing a better understanding of how forest ecosystems function. Additionally, estimation of forest structural attributes, such as aboveground biomass (AGBM), is an important step in identifying the amount of carbon in terrestrial vegetation pools and is central to global carbon …

Sensitivity Of Large-Footprint Lidar To Canopy Structure And Biomass In A Neotropical Rainforest
Drake, J. B., Dubayah, R. O., Knox, R. G., Clark, D. B., Blair, J.

Accurate estimates of the total biomass in terrestrial vegetation are important for carbon dynamics studies at a variety of scales. Although aboveground biomass is difficult to quantify over large areas using traditional techniques, lidar remote sensing holds great promise for biomass estimation because it directly measures components …

Comparative Measurements Of Carbon Dioxide Fluxes From Two Nearby Towers In A Central Amazonian Rainforest: The Manaus Lba Site
Araújo, A. C., Nobre, A. D., Kruijt, B., Elbers, J. A., Dallarosa, R., Stefani, P., von Randow, C., Manzi, A. O., Culf, A. D., Gash, J. H. C., Valentini, R., Kabat, P.

Forests around Manaus have staged the oldest and the longest forest-atmosphere CO2 exchange studies made anywhere in the Amazon. Since July 1999 the exchange of CO2, water, and energy, as well as weather variables, have been measured almost continuously over two forests, 11 km apart, in the Cuieiras reserve near Manaus, Brazil. This …

Fluxes of oxygenated volatile organic compounds from a ponderosa pine plantatio
Schade,G.W., Goldstein,A.H.

We present the first canopy-scale, continuous, long-term flux measurements of a suite of oxygenated volatile organic compounds (OVOCs). Fluxes were measured above a ponderosa pine plantation, adjacent to the Blodgett Forest Research Station (38°53′42.9″N, 120°37′57.9″W, 1315 m elevation), with a fully automated relaxed …

Interannual Variation Of Soil Respiration In Two New England Forests
Savage, K. E., Davidson, E. A.

Soil respiration is an important component of the annual carbon balance of forests, but few studies have addressed interannual variation in soil respiration. The objectives of this study were to investigate the seasonal and interannual variation in soil respiration, temperature, precipitation, and soil water content in two New England …
