Transpiration In Response To Variation In Microclimate And Soil Moisture In Southeastern Deciduous Forests
Oren, R., Pataki, D. E.

Responses of forests to changes in environmental conditions reflect the integrated behavior of their constituent species. We investigated sap flux-scaled transpiration responses of two species prevalent in upland eastern hardwood forests,Journal: Oecologia, Volume 127 (4): 549-559 (2001).

Multiscale Analysis Of Vegetation Surface Fluxes: From Seconds To Years
Katul, G., Lai, C., Schäfer, K., Vidakovic, B., Albertson, J., Ellsworth, D., Oren, R.

The variability in land surface heat (H), water vapor (LE), and CO2 (or net ecosystem exchange, NEE) fluxes was investigated at scales ranging from fractions of seconds to years using eddy-covariance flux measurements above a pine forest. Because these fluxes …

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 …

Spatial And Temporal Variation In Respiration In A Young Ponderosa Pine Forest During A Summer Drought
Law, B., Kelliher, F., Baldocchi, D., Anthoni, P., Irvine, J., Moore, D., Van Tuyl, S.

Respiration rates of heterogeneous forest canopies arise from needles, stems, roots and soil microbes. To assess the temporal and spatial variation in respiration rates of these components in a heterogeneous ponderosa pine forest canopy, and the processes that control these fluxes, we conducted an intensive field study during …

The Impact Of Forest Structure On Near-Ground Temperatures During Two Years Of Contrasting Temperature Extremes
Potter, B. E., Teclaw, R. M., Zasada, J. C.

The thermal environment of clear-cut, partially cut, and uncut forest sites in northern Wisconsin are examined for a warm year and a cool year. Temperatures at 0.5 m above and 0.05 m below ground, as well as base 5°C heat sums are computed for each site between May and …

Large Carbon Isotope Fractionation Associated With Oxidation Of Methyl Halides By Methylotrophic Bacteria
Miller, L. G., Kalin, R. M., McCauley, S. E., Hamilton, J. T., Harper, D. B., Millet, D. B., Oremland, R. S., Goldstein, A. H.

The largest biological fractionations of stable carbon isotopes observed in nature occur during production of methane by methanogenic archaea. These fractionations result in substantial (as much as ≈70‰) shifts in δ13C relative to the initial substrate. We …

Anthropogenic Emission Of Mercury To The Atmosphere In The Northeast United States
Lee, X., Bullock, O. R., Andres, R. J.

The severity and spatial extent of the health impact of anthropogenic mercury (Hg) emission to the atmosphere depend on the emission rate and chemical form of the emitted species. The few measurements of combustion flue gas give highly variable results about how the emission is divided between the elemental (Hg°) and reactive forms …

A Spectral Analysis Of Biosphere–Atmosphere Trace Gas Flux Densities And Meteorological Variables Across Hour To Multi-Year Time Scales
Baldocchi, D., Falge, E., Wilson, K.

The advent of long-term studies on CO2 and water vapor exchange provides us with new information on how the atmosphere and biosphere interact. Conventional time series analysis suggests that temporal fluctuations of weather variables and mass and energy flux densities occur on numerous time scales. The time scales …
