Comparison Of Ecosystem Water-Use Efficiency Among Douglas-Fir Forest, Aspen Forest And Grassland Using Eddy Covariance And Carbon Isotope Techniques
Ponton, S., Flanagan, L. B., Alstad, K. P., Johnson, B. G., Morgenstern, K., Kljun, N., Black, T. A., Barr, A. G.

Comparisons were made among Douglas-fir forest, aspen (broad leaf deciduous) forest and wheatgrass (C₃) grassland for ecosystem-level water-use efficiency (WUE). WUE was defined as the ratio of photosynthetic CO₂ assimilation rate and evapotranspiration (ET) rate. The ET data measured by eddy covariance were …

Impact Of Changing Soil Moisture Distribution On Net Ecosystem Productivity Of A Boreal Aspen Forest During And Following Drought
Krishnan, P., Black, T. A., Grant, N. J., Barr, A. G., Hogg, E. (., Jassal, R. S., Morgenstern, K.

The interannual and seasonal variability of gross ecosystem photosynthesis (P), ecosystem respiration (R) and evapotranspiration
(E), and their relationships to environmental factors were used to explain changes in net ecosystem productivity (FNEP) at the
onset of, during, and following a 3-year-long (2001–2003) drought in a …

Objective Threshold Determination For Nighttime Eddy Flux Filtering
Gu, L., Falge, E. M., Boden, T., Baldocchi, D. D., Black, T., Saleska, S. R., Suni, T., Verma, S. B., Vesala, T., Wofsy, S. C., Xu, L.

We recommend an automated statistical method (Moving Point Test, or MPT) to determine the friction velocity (u_*) thresholds in nighttime eddy flux filtering. Our intention is to make the determination of the u_* thresholds objective and reproducible and to keep flux treatment consistent over …

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

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

Seasonal Variation And Partitioning Of Ecosystem Respiration In A Southern Boreal Aspen Forest
Griffis, T., Black, T., Gaumont-Guay, D., Drewitt, G., Nesic, Z., Barr, A., Morgenstern, K., Kljun, N.

Continuous automatic chamber and eddy covariance (EC) measurements were made at an old aspen forest (SOA) located at southern boreal treeline in Saskatchewan, Canada to examine the temporal variability in soil (R_s), tree bole (R_b), and ecosystem respiration (R_E) during 2001. …

Inter-Annual Variability In The Leaf Area Index Of A Boreal Aspen-Hazelnut Forest In Relation To Net Ecosystem Production
Barr, A. G., Black, T., Hogg, E., Kljun, N., Morgenstern, K., Nesic, Z.

The seasonal phenology of the leaf area index (LAI) is a major determinant of net ecosystem production in deciduous forest ecosystems. This study describes seasonal and inter-annual differences in LAI in a boreal aspen-hazelnut forest in central Saskatchewan, Canada, between 1994 and 2003, and relates the differences in …

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 …

Comparing The Carbon Budgets Of Boreal And Temperate Deciduous Forest Stands
Barr, A. G., Griffis, T. J., Black, T. A., Lee, X., Staebler, R. M., Fuentes, J. D., Chen, Z., Morgenstern, K.

Boreal and temperate deciduous forests at northern mid-latitudes play an important role in the global carbon cycle. We analyze 3 years (1996-1998) of eddy-covariance carbon dioxide flux measurements from two contrasting deciduous forest ecosystems in the boreal and temperate regions of central Canada. The two forest stands have similar …
