Interactive Effects Of Nocturnal Transpiration And Climate Change On The Root Hydraulic Redistribution And Carbon And Water Budgets Of Southern United States Pine Plantations
Domec, J., Ogee, J., Noormets, A., Jouangy, J., Gavazzi, M., Treasure, E., Sun, G., McNulty, S. G., King, J. S.

Deep root water uptake and hydraulic redistribution (HR) have been shown to play a major role in forest ecosystems during drought, but little is known about the impact of climate change, fertilization and soil characteristics on HR and its consequences on water and carbon fluxes. Using data from three mid-rotation loblolly pine plantations, …

How Climate And Vegetation Type Influence Evapotranspiration And Water Use Efficiency In Canadian Forest, Peatland And Grassland Ecosystems
Brümmer, C., Black, T. A., Jassal, R. S., Grant, N. J., Spittlehouse, D. L., Chen, B., Nesic, Z., Amiro, B. D., Arain, M. A., Barr, A. G., Bourque, C. P., Coursolle, C., Dunn, A. L., Flanagan, L. B., Humphreys, E. R., Lafleur, P. M., Margolis, H. A., McCaughey, J. H., Wofsy, S. C.

The effects of climatic factors and vegetation type on evapotranspiration (E) and water use efficiency (WUE) were analyzed using tower-based eddy-covariance (EC) data for nine mature forest sites, two peatland sites and one grassland site across an east–west …

Controls On Carbon Dynamics By Ecosystem Structure And Climate For Southeastern U.S. Slash Pine Plantations
Bracho, R., Starr, G., Gholz, H. L., Martin, T. A., Cropper, W. P., Loescher, H. W.

Abstract. Planted pine forests (plantations) in the southeastern United States are an
important component of the continent’s carbon balance. Forest carbon dynamics are affected
by a range of factors including climatic variability. Multiyear droughts have affected the
region in the past, and an increase in the frequency of drought …

The Challenges Of Measuring Methane Fluxes And Concentrations Over A Peatland Pasture
Baldocchi, D., Detto, M., Sonnentag, O., Verfaillie, J., Teh, Y. A., Silver, W., Kelly, N. M.

We report on methane (CH4) concentrations and efflux densities that were measured over a drained and grazed, peatland pasture in the Sacramento-San Joaquin River Delta of California over a three year period. The site was ideal for micrometeorological flux measurements due to its very flat topography, its …

Ecological Controls On Net Ecosystem Productivity Of A Seasonally Dry Annual Grassland Under Current And Future Climates: Modelling With Ecosys
Grant, R., Baldocchi, D., Ma, S.

Net ecosystem productivity (NEP) of seasonally dry grasslands in Mediterranean climate zones is determined by the duration and intensity of rainy vs. dry seasons. Precipitation in these zones is expected to decline with climate change during the next century, possibly reducing NEP. Ecosystem models used to study climate …

CO2 Fluxes Of A Boreal Black Spruce Chronosequence In Eastern North America
Payeur-Poirier, J., Coursolle, C., Margolis, H. A., Giasson, M.

Forest harvest and subsequent stand development can have major effects on the carbon cycle of boreal stands. Carbon dioxide (CO2) fluxes of a three-point black spruce harvest chronosequence located in the boreal forest of eastern North America were measured over a one-year period at the ecosystem scale with the eddy covariance …
