C-13 Content Of Ecosystem Respiration Is Linked To Precipitation And Vapor Pressure Deficit
Bowling, D., McDowell, N., Bond, B., Law, B., Ehleringer, J.

Variation in the carbon isotopic composition of ecosystem respiration (δ13CR) was studied for 3  years along a precipitation gradient in western Oregon, USA, using the Keeling plot approach. Study sites included six coniferous forests, dominated by Picea sitchensis,

Environmental Controls On Carbon Dioxide Flux From Black Spruce Coarse Woody Debris
Wang, C., Bond-Lamberty, B., Gower, S.

Carbon dioxide flux from coarse woody debris (CWD) is an important source of CO2 in forests with moderate to large amounts of CWD. A process-based understanding of environmental controls on CWD CO2 flux (RCWD) is needed to accurately model carbon exchange between …

Hydrologic Balance In An Intact Temperate Forest Ecosystem Under Ambient And Elevated Atmospheric CO2 Concentration
Schafer, K. V., Oren, R., Lai, C., Katul, G. G.

Increasing atmospheric CO2 concentration decreases stomatal conductance in many species, but the savings of water from reduced transpiration may permit the forest to retain greater leaf area index (L). Therefore, the net effect on water use in forest ecosystems under a higher CO2 atmosphere is difficult …

Forest Carbon Balance Under Elevated CO2
Hamilton, J., Finzi, A., DeLucia, E., George, K., Naidu, S., Schlesinger, W.

Free-air CO2 enrichment (FACE) technology was used to expose a loblolly pine (Pinus taeda L.) forest to elevated atmospheric CO2 (ambient + 200 µl l–1). After 4 years, basal area …

Measurement Carbon Dioxide Concentration Does Not Affect Root Respiration Of Nine Tree Species In The Field
Burton, A. J., Pregitzer, K. S.
Inhibition of respiration has been reported as a short-term response of tree roots to elevated measurement CO2 concentration ([CO2]), calling into question the validity of root respiration rates determined at CO2 concentrations that differ from the soil [CO2] in …

Species Control Variation In Litter Decomposition In A Pine Forest Exposed To Elevated CO2
Finzi, A. C., Schlesinger, W. H.

Net primary production and the flux of dry matter and nutrients from vegetation to soils has increased following four years of exposure to elevated CO2 in a southern …

Observational Constraints On The Contribution Of Isoprene Oxidation To Ozone Production On The Western Slope Of The Sierra Nevada, California
Dreyfus, G. B., Schade, G. W., Goldstein, A. H.

Observations of isoprene and its oxidation products methacrolein (MACR) and methyl vinyl ketone (MVK) are used to quantify the impact of isoprene oxidation on ozone production along the western slope of the Sierra Nevada mountains. Regular daytime up-slope wind flow patterns transport anthropogenic volatile organic compounds (VOC) …

Seasonal Patterns Of Reflectance Indices, Carotenoid Pigments And Photosynthesis Of Evergreen Chaparral Species
Stylinski, C. D., Gamon, J. A., Oechel, W. C.

This study examined the ability of the Photochemical Reflectance Index (PRI) to track seasonal variations in carotenoid pigments and photosynthetic activity of mature evergreen chaparral shrubs. Our results confirm that PRI scales with photosystem two (PSII) …

T., Pilegaard, K., Rannik, Ü., Rebmann, C., Suyker, A., Valentini, R., Wilson, K., Wofsy, S.

Differences in the seasonal pattern of assimilatory and respiratory processes are responsible for divergences in seasonal net carbon exchange among ecosystems. Using FLUXNET data (
