A Physiological Basis For Biosphere-Atmosphere Interactions In The Boreal Forest: An Overview
Margolis, H. A., Ryan, M. G.
Interdisciplinary field experiments for global change research are large, intensive efforts that study the controls on fluxes of carbon, water, trace gases, and energy between terrestrial ecosystems and the atmosphere at a range of spatial scales. Forest ecophysiology can make significant contributions to …

Simulating Forest Productivity And Surface-Atmosphere Carbon Exchange In The BOREAS Study Region
Kimball, J. S., Thornton, P. E., White, M. A., Running, S. W.

A process-based, general ecosystem model (BIOME–BGC) was used to simulate daily gross primary production, maintenance and heterotrophic respiration, net primary production and net ecosystem carbon exchange of boreal aspen, jack pine and black spruce stands. Model simulations of daily net carbon exchange of the ecosystem (NEE) explained …

Seasonal Variation Of Energy And Water Vapor Exchange Rates Above And Below A Boreal Jack Pine Forest Canopy
Baldocchi, D. D., Vogel, C. A., Hall, B.

Fluxes of energy and water vapor over boreal forest stands are expected to vary during the growing season due to temporal variations in solar energy, soil and air temperature, soil moisture, photosynthetic …

Variability In Leaf-Level CO2 And Water Fluxes In Pinus Banksiana And Picea Mariana In Saskatchewan
Sullivan, J. H., Bovard, B. D., Middleton, E. M.
We measured seasonal and canopy-level gas exchange in two stands of jack pine (Pinus banksianaLamb.) and one stand of black spruce (Picea mariana (Mill.) B.S.P.) on relatively clear days from late May until mid-September 1994. Field measurements were made with a portable infrared gas analyzer, …

Root Mass, Net Primary Production And Turnover In Aspen, Jack Pine And Black Spruce Forests In Saskatchewan And Manitoba, Canada
Steele, S. J., Gower, S. T., Vogel, J. G., Norman, J. M.

Root biomass, net primary production and turnover were studied in aspen, jack pine and black spruce forests in two contrasting climates. The climate of the Southern Study Area (SSA) near Prince Albert, Saskatchewan is warmer and drier in the summer and milder in the winter than the Northern Study Area (NSA) near Thompson, Manitoba, …

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 …
