The Seasonal Water And Energy Exchange Above And Within A Boreal Aspen Forest
Blanken, P., Black, T., Neumann, H., den Hartog, G., Yang, P., Nesic, Z., Lee, X.

The seasonal water and energy exchange of a boreal aspen forest underlain by a hazelnut understory is described. Measurements of above-aspen latent and sensible heat, short-wave and net radiation, and photosynthetically active radiation are compared to those measured above the hazelnut understory. Understory radiation measurements …

Response Of Stomatal Conductance To Drought In Ponderosa Pine: Implications For Carbon And Ozone Uptake
Panek, J. A., Goldstein, A. H.
To gain insight into the limitations imposed by a typical Mediterranean-climate summer drought on the uptake of carbon and ozone in the ponderosa pine (Pinus ponderosa Dougl. ex Laws.) ecosystem, we compared diurnal trends in leaf physiology of young trees in a watered and a control plot …

Use Of A Simulation Model And Ecosystem Flux Data To Examine Carbon-Water Interactions In Ponderosa Pine
Williams, M., Law, B. E., Anthoni, P. M., Unsworth, M. H.
Drought stress plays an important role in determining both the structure and function of forest ecosystems, because of the close association between the carbon (C) and hydrological cycles. We used a detailed model of the soil–plant–atmosphere continuum to investigate the links between carbon uptake and …

Elevated CO2 Differentiates Ecosystem Carbon Processes: Deconvolution Analysis Of Duke Forest FACE Data
Luo, Y., Wu, L., Andrews, J. A., White, L., Matamala, R., Schafer, K. V., Schlesinger, W. H.

Factors Controlling Long- And Short-Term Sequestration Of Atmospheric CO2 In A Mid-Latitude Forest
Barford, C. C., Wofsy, S. C., Goulden, M. L., Munger, J. W., Pyle, E. H., Urbanski, S. P., Hutyra, L., Saleska, S. R., Fitzjarrald, D., Moore, K.

Net uptake of carbon dioxide (CO2) measured by eddy covariance in a 60- to 80-year-old forest averaged 2.0 ± 0.4 megagrams of carbon per hectare per year during 1993 to 2000, with interannual variations exceeding 50%. Biometry indicated storage of 1.6 ± 0.4 megagrams of carbon per hectare per year over 8 years, 60% in …

Groundwater Flow Patterns In A Large Peatland
Fraser, C., Roulet, N., Lafleur, M.

Groundwater flow patterns and geochemistry were studied in the Mer Bleue bog, near Ottawa, Ontario, Canada. Groundwater flow patterns alternated between recharge, i.e. head gradients producing flow from the surface of the peatland to the deeper peat, and discharge, i.e. head gradients indicating flow from the deeper peat …

Transpiration In Response To Variation In Microclimate And Soil Moisture In Southeastern Deciduous Forests
Oren, R., Pataki, D. E.

Responses of forests to changes in environmental conditions reflect the integrated behavior of their constituent species. We investigated sap flux-scaled transpiration responses of two species prevalent in upland eastern hardwood forests,Journal: Oecologia, Volume 127 (4): 549-559 (2001), ISBN .

Environmental Controls On Ground Cover Species Composition And Productivity In A Boreal Black Spruce Forest
Bisbee, K., Gower, S., Norman, J., Nordheim, E.

Boreal black spruce forests typically have a dense ground cover of bryophytes. The two main bryophyte groups in boreal black spruce forests, feathermoss and Sphagnum, have ecophysiological characteristics that influence …

Paired-Tower Measurements Of Carbon And Energy Fluxes Following Disturbance In The Boreal Forest
Amiro, B. D.

Disturbances by fire and harvesting are thought to regulate the carbon balance of the Canadian boreal forest over scales of several decades. However, there are few direct measurements …
