Molecular And Carbon Isotopic Composition Of Leaf Wax In Vegetation And Aerosols In A Northern Prairie Ecosystem
Conte, M. H., Weber, J. C., Carlson, P. J., Flanagan, L. B.

We measured the molecular and carbon isotopic composition of major leaf wax compound classes in northern mixed mesic prairie species (Agropyron smithii, Stipa viridula, Bouteloua gracilis,

Annual And Seasonal Variability Of Sensible And Latent Heat Fluxes Above A Coastal Douglas-Fir Forest, British Columbia, Canada
Humphreys, E., Black, T., Ethier, G., Drewitt, G., Spittlehouse, D., Jork, E., Nesic, Z., Livingston, N.

Two years of continuous eddy covariance measurements were used to characterize the seasonal and annual variability of the latent and sensible heat fluxes above a 50-year-old, 33 m tall coastal Douglas-fir forest on the east coast of Vancouver Island, Canada. The total annual evaporation was found to be very conservative …

Oxygen Isotope Content Of CO2 In Nocturnal Ecosystem Respiration: 1. Observations In Forests Along A Precipitation Transect In Oregon, USA
Bowling, D. R., McDowell, N. G., Welker, J. M., Bond, B. J., Law, B. E., Ehleringer, J. R.

The oxygen isotope content of nocturnal ecosystem respiration (δ18OR) was examined in forests along a precipitation gradient in Oregon, USA, to determine whether site-to-site variation in δ18OR was more strongly related to variation in δ18O of precipitation or to evaporative …

Transfer Conductance In Second Growth Douglas-Fir (Pseudotsuga Menziesii (Mirb.)Franco) Canopies
Warren, C. R., Ethier, G. J., Livingston, N. J., Grant, N. J., Turpin, D. H., Harrison, D. L., Black, T. A.

The internal conductance from intercellular spaces to the sites of carboxylation (gi) has only been measured in a few tree species and not in conifers, …

Cross Validation Of Open-Top Chamber And Eddy Covariance Measurements Of Ecosystem CO2 Exchange In A Florida Scrub-Oak Ecosystem
Dore, S., Hymus, G. J., Johnson, D. P., Hinkle, C. R., Valentini, R., Drake, B. G.

Simultaneous measurements of net ecosystem CO2 exchange (NEE) were made in a Florida scrub-oak ecosystem in August 1997 and then every month between April 2000 to …

Partitioning Of Water Flux In A Sierra Nevada Ponderosa Pine Plantation
Kurpius, M., Panek, J., Nikolov, N., McKay, M., Goldstein, A.

The weather patterns of the west side of the Sierra Nevada Mountains (cold, wet winters and hot, dry summers) strongly influence how water is partitioned between transpiration and evaporation and result in a specific strategy of water use by ponderosa pine trees (Pinus …

Species Differences In Stomatal Control Of Water Loss At The Canopy Scale In A Mature Bottomland Deciduous Forest
Pataki, D., Oren, R.

In order to evaluate factors controlling transpiration of six common eastern deciduous species in North America, a model describing responses of canopy stomatal conductance (GS) to net radiation (RN), vapor pressure deficit (D) and relative extractable soil water (REW) was parameterized …

Gas-Phase Chemistry Dominates O3 Loss To A Forest, Implying A Source Of Aerosols And Hydroxyl Radicals To The Atmosphere
Kurpius, M. R., Goldstein, A. H.

Tropospheric ozone (O3) effectively deposits to forested ecosystems but the fate of O3 within the forest canopy is unresolved. We partitioned total measured ecosystem daytime O3 deposition to a ponderosa pine (Pinus ponderosa) forest into its major loss pathways; stomatal uptake, non-stomatal …

Contribution Of Soil Respiration In Tropical, Temperate, And Boreal Forests To The O18 Enrichment Of Atmospheric O2
Angert, A., Barkan, E., Barnett, B., Brugnoli, E., Davidson, E. A., Fessenden, J., Maneepong, S., Panapitukkul, N., Randerson, J. T., Savage, K., Yakir, D., Luz, B.

The 18O content of atmospheric O2 is an important tracer for past changes in the biosphere. Its quantitative use depends on knowledge of the discrimination against 18O associated with the various Oconsumption processes. Here we evaluated, for the first time, the in situ 18O …
