Direct And Indirect Effects Of Atmospheric Conditions And Soil Moisture On Surface Energy Partitioning Revealed By A Prolonged Drought At A Temperate Forest Site
Gu, L., Meyers, T., Pallardy, S. G., Hanson, P. J., Yang, B., Heuer, M., Hosman, K. P., Riggs, J. S., Sluss, D., Wullschleger, S. D.

The purpose of this paper is to examine the mechanism that controls the variation of surface energy partitioning between latent and sensible heat fluxes at a temperate deciduous forest site in central Missouri, USA. Taking advantage of multiple micrometeorological and ecophysiological measurements and a prolonged drought in the middle …

Comparison Of Net Ecosystem CO2 Exchange In Two Peatlands In Western Canada With Contrasting Dominant Vegetation, Sphagnum And Carex
Glenn, A. J., Flanagan, L. B., Syed, K. H., Carlson, P. J.

Net ecosystem carbon dioxide exchange was measured in two contrasting peatlands in northern Alberta, Canada using the eddy covariance technique during the growing season (May–October). Sphagnum spp. made up approximately 66% of the total LAI (1.52 m2 m−2) at the poor fen and the total N content …

Sap Flux-Upscaled Canopy Transpiration, Stomatal Conductance, And Water Use Efficiency In An Old Growth Forest In The Great Lakes Region Of The United States
Tang, J., Bolstad, P. V., Ewers, B. E., Desai, A. R., Davis, K. J., Carey, E. V.

Combining sap flux and eddy covariance measurements provides a means to study plant stomatal conductance and the relationship between transpiration and photosynthesis. We measured sap flux using Granier-type sensors in a northern hardwood-dominated old growth forest in Michigan, upscaled to canopy transpiration, and calculated canopy …

Carbon, Energy And Water Fluxes At Mature And Disturbed Forest Sites, Saskatchewan, Canada
Amiro, B., Barr, A., Black, T., Iwashita, H., Kljun, N., Mccaughey, J., Morgenstern, K., Murayama, S., Nesic, Z., Orchansky, A.

Fire and harvesting are important disturbances in the boreal forest, driving net biome production. Measurements of net ecosystem production (NEP) over mature forest stands have been made from flux towers for about a decade at the Boreal Ecosystem Research and Monitoring Sites (BERMS) in central Saskatchewan, Canada. Over the last …

Ecohydrological Impacts Of Woody-Plant Encroachment: Seasonal Patterns Of Water And Carbon Dioxide Exchange Within A Semiarid Riparian Environment
SCOTT, R. L., HUXMAN, T. E., WILLIAMS, D. G., GOODRICH, D. C.

Across many dryland regions, historically grass-dominated ecosystems have been encroached upon by woody-plant species. In this paper, we compare ecosystem water and carbon dioxide (CO2) fluxes over a grassland, a grassland–shrubland mosaic, and a fully developed woodland to evaluate potential consequences of woody-plant encroachment …

Effects Of Experimental Drought On Soil Respiration And Radiocarbon Efflux From A Temperate Forest Soil
Borken, W., Savage, K., Davidson, E. A., Trumbore, S. E.

Soil moisture affects microbial decay of SOM and rhizosphere respiration (RR) in temperate forest soils, but isolating the response of soil respiration (SR) to summer drought and subsequent wetting is difficult because moisture changes are often confounded with temperature variation. We distinguished between temperature and moisture …

On The Variability Of Respiration In Terrestrial Ecosystems: Moving Beyond Q10
Davidson, E. A., Janssens, I. A., Luo, Y.

Respiration, which is the second most important carbon flux in ecosystems following gross primary productivity, is typically represented in biogeochemical models by simple …

Above- And Belowground Ecosystem Biomass And Carbon Pools In An Age-Sequence Of Temperate Pine Plantation Forests
Peichl, M., Arain, M. A.

We assessed the successional development of above- and belowground ecosystem biomass and carbon (C) pools in an age-sequence of four White pine (Pinus strobus L.) plantation stands (2-, 15-, 30-, and 65-years-old) in Southern Ontario, Canada. Biomass and C stocks of above- and belowground live and dead tree biomass, understorey …
