Contributions Of Interacting Biological Mechanisms To Soil Aggregate Stabilization In Restored Prairie
Jastrow, J., Miller, R., Lussenhop, J.

A better understanding of the soil aggregation process is needed to address a variety of concerns, including soil quality and erosion, agricultural sustainability, soil C sequestration, the mobility of hazardous chemicals and remediation of contaminated sites. We used data …

On Using Eco-Physiological, Micrometeorological And Biogeochemical Theory To Evaluate Carbon Dioxide, Water Vapor And Trace Gas Fluxes Over Vegetation: A Perspective
Baldocchi, D., Meyers, T.

How eco-physiological, biogeochemical and micrometeorological theory can be used to compute biosphere–atmosphere, trace gas exchange rates is discussed within the framework of a process model. The accuracy of the theory is tested by comparing computations of mass and energy flux densities (water vapor, sensible heat, CO2

Relationships Of Leaf Dark Respiration To Leaf Nitrogen, Specific Leaf Area And Leaf Life-Span: A Test Across Biomes And Functional Groups
Reich, P. B., Walters, M. B., Ellsworth, D. S., Vose, J. M., Volin, J. C., Gresham, C., Bowman, W. D.

Based on prior evidence of coordinated multiple leaf trait scaling, we hypothesized that variation among species in leaf dark respiration rate (Rd) should scale with variation in traits such as leaf nitrogen (N), leaf life-span, specific leaf area (SLA), and net photosynthetic capacity …

Climatology Of Gravity Waves In A Forest
Lee, X., Barr, A. G.

The objectives of this study are to establish a climatology of gravity waves in a forest and to gain insights into the dynamics of this motion type. The site is part of the BOREAS (Boreal Ecosystem—Atmosphere Study) flux monitoring network. The analysis relies mainly on 5 Hz temperature time series observed with two arrays of fine-wire …

Simple And Fast Technique To Measure CO2 Profiles In Soil
Fang, C., Moncrieff, J.

We describe a simple method for sampling soil gas at different profile depths and analyzing CO2 concentration in the gas sample. Soil gas samples were taken on the soil surface from each chosen depth through a gas circulation system and analyzed in situ

Intercomparison Among Chamber, Tower, And Aircraft Net CO2 And Energy Fluxes Measured During The Arctic System Science Land-Atmosphere-Ice Interactions (ARCSS-LAII) Flux Study
Oechel, W. C., Vourlitis, G. L., Brooks, S., Crawford, T. L., Dumas, E.

Measurements of net ecosystem CO2 exchange (NEE) and energy balance were made using chamber-, tower-, and aircraft-based measurement techniques in Alaskan arctic tundra ecosystems during the 1994–1995 …

Controls Over Monoterpene Emissions From Boreal Forest Conifers
Lerdau, M., Litvak, M., Palmer, P., Monson, R.

We investigated controls over the emission of monoterpenes from two species of boreal forest conifers, black spruce (Picea mariana Miller (B.S.P.)) and jack pine (Pinus banksiana Lamb). Monoterpenes are important in plants as carbon-based defensive compounds and in the atmosphere as photochemically reactive compounds …

Transpiration Of A Boreal Pine Forest Measured By Branch Bag, Sap Flow And Micrometeorological Methods
Saugier, B., Granier, A., Pontailler, J. Y., Dufrene, E., Baldocchi, D. D.

Three independent methods were used to evaluate transpiration of a boreal forest: the branch bag, sap flow and eddy covariance methods. The branch bag method encloses several thousand needles and gives a continuous record of branch transpiration. The sap flow method provides a continuous record of sap velocity and an estimate of …
