Influence Of Climate And Fertilization On Net Photosynthesis Of Mature Slash Pine
Teskey, R. O., Gholz, H. L., Cropper, W. P.

Net photosynthesis was measured under field conditions in 23-year-old slash pine (Pinus elliottii Engelm. var. elliottii) trees to determine how it was affected by fertilization and climate. There was only a small decrease in rates of net photosynthesis from late summer through winter demonstrating that appreciable …

Estimating Total Soil Mass, Nutrient Content, And Trace Metals In Soils Under A Low Elevation Spruce-Fir Forest
Fernandez, I. J., Rustad, L. E., Lawrence, G. B.

The concentration, contents, and distribution of nutrients, metals, and soil materials were quantified at the Howland Integrated Forest Study (HIFS) site in eastern Maine. The …

Ozone Deposition Onto A Deciduous Forest During Dry And Wet Conditions
Fuentes, J., Gillespie, T., den Hartog, G., Neumann, H.

Results of an experiment conducted to quantify the ozone deposition onto a deciduous forest stand in an acid-precipitation-impacted area of Canada are presented and discussed. The ozone deposition data were obtained above and within the forest canopy. The deposition process …

Dynamics Of Canopy Structure And Light Interception In Pinus Elliottii Stands, North Florida
Gholz, H. L., Vogel, S. A., Cropper, W. P., McKelvey, K., Ewel, K. C., Teskey, R. O., Curran, P. J.

In order to develop a model of the carbon cycle for mature slash pine (Pinus elliottii) stands in north Florida, we studied seasonal variation in leaf area index (LAI, allsided), aboveground biomass increment …

Trace Gas Exchange Above The Floor Of A Deciduous Forest: 1. Evaporation And CO2 Efflux
Baldocchi, D. D., Meyers, T. P.

The eddy correlation method has great potential for directly measuring trace gas fluxes at the floor of a forest canopy, but a thorough validation study has not been yet conducted. Another appeal of the eddy …

A comparison of direct and indirect methods for estimating forest canopy leaf area
Chason, J. Huston, M. D. D. Baldocchi

Two indirect gap fraction methods for estimating leaf area index (LAI) are compared with estimates
from litterfall collections in a mixed-age oak-hickory forest. One indirect method uses averaged,
direct beam penetration data obtained with a moving tram. The second uses a portable light
sensor system that measures diffuse light …

A Numerical Model For Simulating The Radiation Regime Within A Deciduous Forest Canopy
Wang, H., Baldocchi, D. D.

A numerical model that simulates the radiation regime inside a fully leafed and leafless deciduous forest canopy is discussed and tested. The model incorporates features which account for the vertical variation in leaf inclination angles and penumbral effects; these features have been experimentally shown to significantly influence …

A Field Investigation Of Sulfate Fluxes To A Deciduous Forest
Hicks, B. B., Matt, D. R., McMillen, R. T., Womack, J. D., Wesely, M. L., Hart, R. L., Cook, D. R., Lindberg, S. E., Depena, R. G., Thomson, D. W.

An intensive investigation of particulate sulfur fluxes to a deciduous forest was conducted at Oak Ridge, Tennessee, during May 1983, as part of a multilaboratory program to study the dry deposition of airborne trace gases and aerosols to vegetated surfaces. At this time, the leaf area was approximately 50% of the maximum and was …

Turbulent Transfer In A Deciduous Forest
Baldocchi, D. D.
Carbon dioxide, water vapor and other passive scalars are physically transferred between a plant canopy and the atmosphere by turbulence. Intense and intermittent sweep and ejection events transfer most of the mass. Although the capacity for turbulence to transfer material is high, mass transfer is coupled …
