Incorporating Spatial Heterogeneity Created By Permafrost Thaw Into A Landscape Carbon Estimate
Belshe, E. F., Schuur, E. A., Bolker, B. M., Bracho, R.

The future carbon balance of high-latitude ecosystems is dependent on the sensitivity of biological processes (photosynthesis and respiration) to the physical changes occurring with permafrost thaw. Predicting C exchange in these ecosystems is difficult because the thawing of permafrost is a heterogeneous process that creates a complex …

Effects Of Water Availability On Carbon And Water Exchange In A Young Ponderosa Pine Forest: Above- And Belowground Responses
Ruehr, N. K., Martin, J. G., Law, B. E.

Changes in the hydrological cycle, as predicted and currently observed, are expected to significantly impact the water and carbon balance of water-limited forest ecosystems. However, differences in the water-sensitivity of component processes make carbon balance predictions challenging. To examine responses of ecosystem components …

Influence Of Stand Age On The Magnitude And Seasonality Of Carbon Fluxes In Canadian Forests
Coursolle, C., Margolis, H., Giasson, M., Bernier, P., Amiro, B., Arain, M., Barr, A., Black, T., Goulden, M., McCaughey, J., Chen, J., Dunn, A., Grant, R., Lafleur, P.

Proper management and accounting of forest carbon requires good knowledge of how disturbances and climate affect the carbon dynamics of different stand types. We have investigated such relationships by measuring, over a 5-year period (2003–2007), the net ecosystem productivity (NEP), gross ecosystem productivity …

Creating Wetlands: Primary Succession, Water Quality Changes, And Self-Design Over 15 Years
Mitsch, W. J., Zhang, L., Stefanik, K. C., Nahlik, A. M., Anderson, C. J., Bernal, B., Hernandez, M., Song, K.
The succession of vegetation, soil development, water quality changes, and carbon and nitrogen dynamics are summarized in this article for a pair of 1-hectare flow-through-created riverine wetlands for their first 15 years. Wetland plant richness increased from 13 originally planted species to 116 species …

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 …

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 …

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 …

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 …
