Factors Controlling The Interannual Variability In The Carbon Balance Of A Southern Boreal Black Spruce Forest
Krishnan, P., Black, T. A., Barr, A. G., Grant, N. J., Gaumont-Guay, D., Nesic, Z.

Factors controlling the seasonal and interannual variability of net ecosystem
productivity (FNEP), gross ecosystem photosynthesis (Pg), ecosystem respiration (Re) and
evapotranspiration (E) of a mature boreal black spruce forest in central Saskatchewan,
Canada were investigated using eight years (1999–2006) of continuous eddy …

Comparison Of Carbon Dioxide Fluxes Over Three Boreal Black Spruce Forests In Canada
Bergeron, O., Margolis, H. A., Black, T. A., Coursolle, C., Dunn, A. L., Barr, A. G., Wofsy, S. C.

Although mature black spruce forests are a dominant cover type in the boreal forest of North America, it is not clear how their carbon (C) budgets vary across the continent. …

A Global Relationship Between The Heterotrophic And Autotrophic Components Of Soil Respiration?
Bond-Lamberty, B., Wang, C., Gower, S. T.

Soil surface CO2 flux (RS) is overwhelmingly the product of respiration by roots (autotrophic respiration, RA) and soil organisms (heterotrophic respiration, RH). Many studies have attempted to partition RS into these two components, with highly …

A Cross-Biome Comparison Of Daily Light Use Efficiency For Gross Primary Production
Turner, D. P., Urbanski, S., Bremer, D., Wofsy, S. C., Meyers, T., Gower, S. T., Gregory, M.

Vegetation light use efficiency is a key physiological parameter at the canopy scale, and at the daily time step is a component of remote sensing algorithms for scaling gross …

Comparison Of Net Primary Production And Light-Use Dynamics Of Two Boreal Black Spruce Forest Communities
O'Connell, K. E., Gower, S. T., Norman, J. M.

Black spruce (Picea mariana [Mill.] BSP) is the most dominant forest ecosystem in the North American boreal region. There are at least two contrasting boreal black spruce forest communities: open-canopy black spruce overstory with Sphagnum ground cover (BSSP) and closed-canopy black spruce overstory with feathermoss ground cover …

Relationship Of Area-Averaged Carbon Dioxide And Water Vapour Fluxes To Atmospheric Variables
Mahrt, L., Vickers, D.

Area-averaged fluxes are constructed from a combination of aircraft and tower data collected during BOREAS. The averaging area includes both conifer and deciduous forests, wetlands, burned areas and bodies of water. The area-averaged water vapour flux is closely related …

Photosynthesis And Respiration Of Black Spruce At Three Organizational Scales: Shoot, Branch And Canopy
Rayment, M. B., Loustau, D., Jarvis, P. J.
To gain insight into the function of photosynthesis and respiration as processes operating within a global ecosystem, we measured gas exchange of mature black spruce (Picea mariana (Mill.) B.S.P.) trees at three organizational scales: individual shoots, whole branches and a forest canopy. A biochemical …

Environmental Regulation Of Carbon Dioxide Exchange At The Forest Floor In A Boreal Black Spruce Ecosystem
Swanson, R. V., Flanagan, L. B.

Measurements of CO2 exchange at the forest floor were made in shady dry areas dominated by feather mosses and open wet areas dominated by Sphagnum mosses within a 120-year-old black spruce forest in central Saskatchewan during 1996. Our objective was to study the environmental regulation of moss photosynthesis …
