Plant Biomass And Production And CO2 Exchange In An Ombrotrophic Bog
Moore, T. R., Bubier, J. L., Frolking, S. E., Lafleur, P. M., Roulet, N. T.
  1. Above-ground biomass was measured at bog hummock, bog hollow and poor-fen sites in Mer Bleue, a large, raised ombrotrophic bog near Ottawa, Ont., Canada. The average above-ground biomass was 587 g m−2 in the bog, composed mainly of shrubs and Sphagnum capitula. In the poor fen, the …

Relationship Of Area-Averaged Carbon Dioxide And Water Vapour Fluxes To Atmospheric Variables
Mahrt, L., Vickers, D.

Area-averaged fluxes are constructed from a combination of aircraft and tower data collected during BOREAS. The averaging area includes both conifer and deciduous forests, wetlands, burned areas and bodies of water. The area-averaged water vapour flux is closely related …

Annual Ozone Deposition To A Sierra Nevada Ponderosa Pine Plantation
Kurpius, M., McKay, M., Goldstein, A.

Ozone concentration and ecosystem scale fluxes were measured continuously from June 1999 to June 2000 above a ponderosa pine plantation at Blodgett Forest, an Ameriflux site located ∼75 km northeast of Sacramento, CA (1300 m). The ponderosa pine trees were most active …

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 …
