Modeling Radiation And Photosynthesis Of A Heterogeneous Savanna Woodland Landscape With A Hierarchy Of Model Complexities
Chen, Q., Baldocchi, D., Gong, P., Dawson, T.

Simple but realistic modeling of radiation transfer within heterogeneous canopy has been a challenging research question for decades and is critical for predicting ecological processes such as photosynthesis. The Markov model proposed by [Nilson, T., 1971. A theoretical analysis of the frequency of gaps in plant stands. Agric. Meteorol. …

Temporal Changes In C And N Stocks Of Restored Prairie: Implications For C Sequestration Strategies
Matamala, R., Jastrow, J. D., Miller, R. M., Garten, C. T.

The recovery of ecosystem C and N dynamics after disturbance can be a slow process. Chronosequence approaches offer unique opportunities to use space-for-time substitution to quantify the recovery of ecosystem …

Estimating Components Of Forest Evapotranspiration: A Footprint Approach For Scaling Sap Flux Measurements
Oishi, A. C., Oren, R., Stoy, P. C.

Forest evapotranspiration (ET) estimates that include scaled sap flux measurements often underestimate eddy covariance (EC)-measured latent heat flux (LE). We investigated potential causes for this bias using 4 years of coupled sap flux and LE measurements from a mature oak-hickory forest in North Carolina, USA. We focused on accuracy …

Modeling Analysis Of Primary Controls On Net Ecosystem Productivity Of Seven Boreal And Temperate Coniferous Forests Across A Continental Transect
Yuan, F., Arain, M. A., Barr, A. G., Black, T. A., Bourque, C. P., Coursolle, C., Margolis, H. A., Mccaughey, J. H., Wofsy, S. C.

Process-based models are effective tools to synthesize and/or extrapolate measured carbon (C) exchanges from individual sites to large scales. In this study, we used a C- and …

Role Of Vegetation In Determining Carbon Sequestration Along Ecological Succession In The Southeastern United States
Stoy, P. C., Katul, G. G., Siqueira, M. B., Juang, J., Novick, K. A., Mccarthy, H. R., Oishi, A. C., Oren, R.

Vegetation plays a central role in controlling terrestrial carbon (C) exchange, but quantifying its impacts on C cycling on time scales of ecological succession is hindered …

Direct Measurement Of Biosphere-Atmosphere Isotopic Co2exchange Using The Eddy Covariance Technique
Griffis, T.J., Sargent, S.D., Baker, J.M., Lee, X., Tanner, B.D., Greene, J., Swiatek, E., Billmark, K.

Quantifying isotopic CO2 exchange between the biosphere and atmosphere presents a significant measurement challenge, but has the potential to provide important constraints on local, regional, and global carbon cycling. Past approaches have indirectly estimated isotopic CO2 exchange using relaxed eddy accumulation, …

Drought During Canopy Development Has Lasting Effect On Annual Carbon Balance In A Deciduous Temperate Forest
Noormets, A., McNulty, S. G., DeForest, J. L., Sun, G., Li, Q., Chen, J.
  • Climate change projections predict an intensifying hydrologic cycle and an increasing frequency of droughts, yet quantitative understanding of the effects on ecosystem carbon exchange remains limited.
  • Here, the effect of contrasting precipitation and soil moisture dynamics were evaluated …

Long-Term Impact Of A Stand-Replacing Fire On Ecosystem CO2 Exchange Of A Ponderosa Pine Forest
Dore, S., Kolb, T. E., Montes-Helu, M., Sullivan, B. W., Winslow, W. D., Hart, S. C., Kaye, J. P., Koch, G. W., Hungate, B. A.

Ponderosa pine (Pinus ponderosa) forests of the southwestern United States are a mosaic of stands where undisturbed forests are carbon sinks, and stands recovering from wildfires may be sources of carbon to the atmosphere for decades after the fire. However, the relative magnitude of these sinks and sources has never been …
