Comparison Of Soil Organic Matter Dynamics At Five Temperate Deciduous Forests With Physical Fractionation And Radiocarbon Measurements
McFarlane, K. J., Torn, M. S., Hanson, P. J., Porras, R. C., Swanston, C. W., Callaham, M. A., Guilderson, T. P.

Forest soils represent a significant pool for carbon sequestration and storage, but the factors controlling soil carbon cycling are not well constrained. We compared soil carbon dynamics at five broadleaf forests in the Eastern US that vary in climate, soil type, and soil ecology: two sites at the University of Michigan Biological …

Sensitivity Of The Backscatter Intensity Of Alos/Palsar To The Above-Ground Biomass And Other Biophysical Parameters Of Boreal Forest In Alaska
Suzuki, R., Kim, Y., Ishii, R.

We investigated the potential of ALOS/PALSAR for estimating the above-ground biomass (AGB) and other biophysical pa- rameters (tree height, diameter at breast height (DBH), and tree stand density) in the boreal forest of Alaska. In July 2007, forest surveys were conducted along a southenorth transect (150 W) to profile the ecotone …

Initial Carbon Dynamics Of Perennial Grassland Conversion For Annual Cropping In Manitoba
Fraser, T. J., Amiro, B. D.

Fraser, T. J. and Amiro, B. D. 2013. Initial carbon dynamics of perennial grassland conversion for annual cropping in Manitoba. Can. J. Soil Sci. 93: 379–391. Sequestering atmospheric carbon in agricultural soil is an attractive option for mitigation of rising atmospheric carbon dioxide concentrations. Perennial crops …

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 …
