Photosynthesis, Carboxylation And Leaf Nitrogen Responses Of 16 Species To Elevated pCO2 Across Four Free-Air CO2 Enrichment Experiments In Forest, Grassland And Desert
Ellsworth, D. S., Reich, P. B., Naumburg, E. S., Koch, G. W., Kubiske, M. E., Smith, S. D.

The magnitude of changes in carboxylation capacity in dominant plant species under long-term elevated CO2 exposure (elevated pCa) directly impacts …

Impacts Of Fine Root Turnover On Forest NPP And Soil C Sequestration Potential
Matamala, R., Gonzalez-Meler, M. A., Jastrow, J. D., Norby, R. J., Schlesinger, W. H.

Estimates of forest net primary production (NPP) demand accurate estimates of root production and turnover. We assessed root turnover with the use of an isotope tracer in two forest free-air carbon dioxide enrichment experiments. Growth at elevated carbon dioxide did not accelerate root turnover in either the pine or the hardwood …

Reduction Of Forest Floor Respiration By Fertilization On Both Carbon Dioxide-Enriched And Reference 17-Year-Old Loblolly Pine Stands
Butnor, J. R., Johnsen, K. H., Oren, R., Katul, G. G.

Elevated atmospheric carbon dioxide (CO2e) increases soil respiration rates in forest, grassland, agricultural and wetland systems as a result of increased …

Partitioning Interannual Variability In Net Ecosystem Exchange Between Climatic Variability And Functional Change
Hui, D., Luo, Y., Katul, G.
Interannual variability (IAV) in net ecosystem exchange of carbon (NEE) is a critical factor in projections of future ecosystem changes. However, our understanding of IAV is limited because of the difficulty in isolating its numerous causes. We proposed that IAV in NEE is primarily caused by climatic variability, …

Soil-Nitrogen Cycling In A Pine Forest Exposed To 5 Years Of Elevated Carbon Dioxide
Finzi, A. C., Schlesinger, W. H.

Empirical and modeling studies have shown that the magnitude and duration of the primary production response to elevated carbon dioxide (CO2) can be constrained by limiting supplies of soil nitrogen (N). We have studied the response of a southern …

Relationship Between Plant Hydraulic And Biochemical Properties Derived From A Steady-State Coupled Water And Carbon Transport Model
Katul, G., Leuning, R., Oren, R.

There is growing evidence that plant stomata have evolved physiological controls to satisfy the demand for CO2 by photosynthesis while regulating water losses by …

Exposure To An Enriched CO2 Atmosphere Alters Carbon Assimilation And Allocation In A Pine Forest Ecosystem
Schafer, K. V., Oren, R., Ellsworth, D. S., Lai, C., Herrick, J. D., Finzi, A. C., Richter, D. D., Katul, G. G.

We linked a leaf-level CO2 assimilation model with a model that accounts for light attenuation in the canopy and measurements of sap-flux-based canopy conductance into a new canopy conductance-constrained carbon assimilation (4C-A) model. We estimated canopy CO2 uptake (AnC) at the Duke Forest …
