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 …

Measurements Of CO2 And Energy Fluxes Over A Mixed Hardwood Forest In The Mid-Western United States
Schmid, H., Grimmond, C.S.B., Cropley, F., Offerle, B., Su, H.B.

Results from the first full year of measurements (1998–1999) of above canopy CO2 and energy fluxes at the AmeriFlux site in the Morgan-Monroe State Forest, IN, USA, are presented. The site is located in an extensive secondary successional broadleaf forest in the maple-beech to oak-hickory transition zone. The …

Long-Term Impacts Of Agriculture On Soil Carbon And Nitrogen In New England Forests
Compton, J. E., Boone, R. D.

Abandonment and reforestation of agricultural lands has been a major influence on the landscape of eastern North America. Cultivation and soil amendments can dramatically alter soil nutrient pools and cycling, …

Canopy And Leaf Level 2-Methyl-3-Buten-2-Ol Fluxes From A Ponderosa Pine Plantation
Schade, G. W., Goldstein, A. H., Gray, D. W., Lerdau, M. T.

Canopy and leaf level 2-methyl-3-butene-2-ol (methylbutenol, MBO) emissions were measured from a ponderosa pine plantation in the Sierra Nevada mountains from July to October 1998. Canopy scale fluxes were measured using a gradient approach, leaf level fluxes used a flow-through …

The Dynamic Role Of Root-Water Uptake In Coupling Potential To Actual Transpiration
Lai, C., Katul, G.

The relationship between actual (Eact) and potential (Ep) transpiration above a grass-covered forest clearing was investigated numerically and experimentally from simultaneous measurements of soil moisture content profiles, mean meteorological …

Quantifying Simultaneous Fluxes Of Ozone, Carbon Dioxide And Water Vapor Above A Subalpine Forest Ecosystem
Zeller, K., Nikolov, N.

Assessing the long-term exchange of trace gases and energy between terrestrial ecosystems and the atmosphere is an important priority of the current climate change research. In this regard, it is particularly significant to provide valid data on simultaneous fluxes of carbon, …

Effects Of Climate Variability On The Carbon Dioxide, Water, And Sensible Heat Fluxes Above A Ponderosa Pine Plantation In The Sierra Nevada (CA)
Goldstein, A., Hultman, N., Fracheboud, J., Bauer, M., Panek, J., Xu, M., Qi, Y., Guenther, A., Baugh, W.

Fluxes of CO2, water vapor, and sensible heat were measured by the eddy covariance method above a young ponderosa pine plantation in the Sierra Nevada Mountains (CA) over two growing seasons (1 June–10 September 1997 and 1 May–30 October 1998). The Mediterranean-type climate of California is characterized by a protracted …
