Quantification Of Upland Thermokarst Features With High Resolution Remote Sensing
Belshe, E. F., Schuur, E. A., Grosse, G.

Climate-induced changes to permafrost are altering high latitude landscapes in ways that could increase the vulnerability of the vast soil carbon pools of the region. Permafrost thaw is temporally dynamic and spatially heterogeneous because, in addition to the thickening of the active …

Antecedent Conditions Influence Soil Respiration Differences In Shrub And Grass Patches
Cable, J. M., Ogle, K., Barron-Gafford, G. A., Bentley, L. P., Cable, W. L., Scott, R. L., Williams, D. G., Huxman, T. E.

Quantifying the response of soil respiration to past environmental conditions is critical for predicting how future climate and vegetation change will impact ecosystem carbon balance. Increased shrub dominance in semiarid grasslands has potentially large effects on soil carbon cycling. The goal of this study was to characterize the …

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 …

Greenhouse Gas (CO2, CH4, H2O) Fluxes From Drained And Flooded Agricultural Peatlands In The Sacramento-San Joaquin Delta
Hatala, J. A., Detto, M., Sonnentag, O., Deverel, S. J., Verfaillie, J., Baldocchi, D. D.

The Sacramento-San Joaquin Delta in California was drained and converted to agriculture more than a century ago, and since then has experienced extreme rates of soil subsidence from peat oxidation. To reverse subsidence and capture carbon there is increasing interest in converting drained agricultural land-use types …

On The Choice Of The Driving Temperature For Eddy-Covariance Carbon Dioxide Flux Partitioning

Old-Growth CO2 Flux Measurements Reveal High Sensitivity To Climate Anomalies Across Seasonal, Annual And Decadal Time Scales
Wharton, S., Falk, M., Bible, K., Schroeder, M., Paw U, K.T.

The traditional hypothesis that old-growth forests are carbon neutral is under debate as recent studies
show evidence of net carbon sequestration. Here, we present a decade (1998–2008) of carbon dioxide,
water and energy fluxes from an old-growth stand in the American Pacific Northwest to identify
ecosystem-level responses to …

The Role Of Harvest Residue In Rotation Cycle Carbon Balance In Loblolly Pine Plantations. Respiration Partitioning Approach
Noormets, A., McNulty, S. G., Domec, J., Gavazzi, M., Sun, G., King, J. S.

Timber harvests remove a significant portion of ecosystem carbon. While some of the wood products moved off-site may last past the harvest cycle of the particular forest crop, the effect of the episodic disturbances …

Increased CO2 Loss From Vegetated Drained Lake Tundra Ecosystems Due To Flooding
Zona, D., Lipson, D. A., Paw U, K. T., Oberbauer, S. F., Olivas, P., Gioli, B., Oechel, W. C.

Tundra ecosystems are especially sensitive to climate change, which is particularly rapid in high northern latitudes resulting in significant alterations in temperature and soil moisture. Numerous studies have demonstrated that soil drying increases the respiration loss from wet Arctic tundra. And, warming and drying of tundra soils …
