An Analysis Of Soil Respiration Across Northern Hemisphere Temperate Ecosystems
Hibbard, K. A., Law, B. E., Reichstein, M., Sulzman, J.

Over two-thirds of terrestrial carbon is stored belowground and a significant amount of atmospheric CO2 is respired by roots and microbes in soils. For this analysis, soil respiration (Rs) data were assembled from 31 AmeriFlux and CarboEurope sites representing deciduous broadleaf, evergreen needleleaf, grasslands, mixed …

Soil Properties Differently Influence Estimates Of Soil CO2 Efflux From Three Chamber-Based Measurement Systems
Butnor, J. R., Johnsen, K. H., Maier, C. A.

Soil CO2 efflux is a major component of net ecosystem productivity (NEP) of forest systems. Combining data from multiple researchers for larger-scale modeling and assessment will only be valid if their methodologies provide directly comparable …

Contrasting Responses To Drought Of Forest Floor CO2 Efflux In A Loblolly Pine Plantation And A Nearby Oak-Hickory Forest
Palmroth, S., Maier, C. A., McCarthy, H. R., Oishi, A. C., Kim, H., Johnsen, K., Katul, G. G., Oren, R.

Forest floor CO2 efflux (Fff) depends on vegetation type, climate, and soil physical properties. We assessed the effects of biological factors on Fff by comparing a maturing pine plantation (PP) and a nearby mature Oak-Hickory-type hardwood forest (HW). Fff was …

Foliage Shedding In Deciduous Forests Lifts Up Long-Distance Seed Dispersal By Wind
Nathan, R., Katul, G. G.

Seed terminal velocity and release height are recognized as key biotic determinants of long-distance dispersal (LDD) of seeds by wind. Yet, potential determinants at the ecosystem level, such as seasonal dynamics in foliage density characterizing many deciduous forests, have received much less attention. We integrated detailed field …

Net Ecosystem Production In A Temperate Pine Plantation In Southeastern Canada
Arain, M. A., Restrepo-Coupe, N.

Eddy covariance measurements of carbon dioxide (CO2) and water vapour fluxes were made from June 2002 to May 2003 over a 65-year-old temperate conifer plantation forest in southern Ontario, Canada. This site is part of a newly initiated long-term tower flux measurement …

Respiratory Carbon Use And Carbon Storage In Mid-Rotation Loblolly Pine (Pinus Taeda L.) Plantations: The Effect Of Site Resources On The Stand Carbon Balance
Maier, C. A., Albaugh, T. J., Allen, H. L., Dougherty, P. M.

We used estimates of autotrophic respiration (RA), net primary productivity (NPP) and soil CO2 evolution (Sff), to develop component carbon budgets for 12-year-old loblolly pine plantations during the fifth year of a fertilization and irrigation experiment. Annual carbon use in RA

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 …

Response To Comment On "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.

A Global Relationship Between The Heterotrophic And Autotrophic Components Of Soil Respiration?
Bond-Lamberty, B., Wang, C., Gower, S. T.

Soil surface CO2 flux (RS) is overwhelmingly the product of respiration by roots (autotrophic respiration, RA) and soil organisms (heterotrophic respiration, RH). Many studies have attempted to partition RS into these two components, with highly …

Gap-Filling Missing Data In Eddy Covariance Measurements Using Multiple Imputation (MI) For Annual Estimations
Hui, D., Wan, S., Su, B., Katul, G., Monson, R., Luo, Y.

Missing data is a ubiquitous problem in evaluating long-term experimental measurements, such as those associated with the FluxNet project, due to the equipment failures, system maintenance, power-failure, and lightning strikes among other things. To estimate annual values …
