Contrasting strategies of hydraulic control in two co-dominant temperate tree species
Matheny AM, Fiorella RP, Bohrer G, Poulsen CJ, Morin TH, Wunderlich A, Vogel CS, Curtis PS.
Biophysical controls on plant water status exist at the leaf, stem, and root levels. Therefore, we pose that hydraulic strategy is a combination of traits governing water use at each of these three levels. We studied sap flux, stem water storage, stomatal conductance, photosynthesis, and growth of red oaks (Quercus rubra) and…

Delta-Flux: An Eddy Covariance Network for a Climate-Smart Lower Mississippi Basin
Benjamin R. K. Runkle, James R. Rigbyb, Michele L. Rebac, Saseendran S. Anapallid, Joydeep Bhattacharjeee, Ken W. Kraussf, Lu Liangg, Martin A. Locke, Kimberly A. Novick, Ruixiu Suid, Kosana Suvočareva and Paul M. White
Networks of remotely monitored research sites are increasingly the tool used to study regional agricultural impacts on carbon and water fluxes. However, key national networks such as the National Ecological Observatory Network and AmeriFlux lack contributions from the Lower Mississippi River Basin (LMRB), a highly productive agr…

The impact of expanding flooded land area on the annual evaporation of rice. Agricultural and Forest Meteorology
Baldocchi, D., S. Knox, I. Dronova, J. Verfaillie, P. Oikawa, C. Sturtevant, J. H. Matthes, and M. Detto.
The amount of published data on annual evaporation on rice remains extremely limited despite the role of rice as a key food source. We report on six years of rice evaporation measurements, based on the eddy covariance method. This rice was cultivated in the hot dry climate of California, where water is a scarce and precious reso…

Biophysical controls on interannual variability in ecosystem-scale CO2 and CH4 exchange in a California rice paddy.
Knox, S. H., J. H. Matthes, C. Sturtevant, P. Y. Oikawa, J. Verfaillie, and D. Baldocchi.
We present 6.5 years of eddy covariance measurements of fluxes of methane (FCH4) and carbon dioxide (FCO2) from a flooded rice paddy in Northern California, USA. A pronounced warming trend throughout the study associated with drought and record high temperatures strongly influenced carbon (C) budgets and provided insights into…

Does day and night sampling reduce spurious correlation between canopy photosynthesis and ecosystem respiration?
Dennis Baldocchi, Cove Sturtevant
It is necessary to partition eddy covariance measurements of carbon dioxide exchange into its offsetting gross fluxes, canopy photosynthesis, and ecosystem respiration, to understand the biophysical controls on the net fluxes. And independent estimates of canopy photosynthesis (G) and ecosystem respiration (R) are needed to vali…

Using digital camera and Landsat imagery with eddy covariance data to model gross primary production in restored wetlands
Knox, Sara Helen Dronova, Iryna Sturtevant, Cove Oikawa, Patricia Y. Matthes, Jaclyn Hatala Verfaillie, Joseph Baldocchi, Dennis
Wetlands have the ability to accumulate large amounts of carbon (C), and therefore wetland restoration has been proposed as a means of sequestering atmospheric carbon dioxide (CO2) to help mitigate climate change. There is a growing interest in using the C services of wetlands to help reduce habitat loss and finance restoration …

Influence of regional nighttime atmospheric regimes on canopy turbulence and gradients at a closed and open forest in mountain-valley terrain
Wharton, S.; Ma, S.; Baldocchi, D.D.; Falk, M.; Newman, J.F.; Osuna, J.L.; Bible, K.
Stable stratification of the nocturnal lower boundary layer inhibits convective turbulence, such that turbulent vertical transfer of ecosystem carbon dioxide (CO2), water vapor (H2O) and energy is driven by mechanically forced turbulence, either from frictional forces near the ground or top of a plant canopy, or from shear gener…

Evaluation of a hierarchy of models reveals importance of substrate limitation for predicting carbon dioxide and methane exchange in restored wetlands
Oikawa, P. Y.; Jenerette, G. D.; Knox, S. H.; Sturtevant, C.; Verfaillie, J.; Dronova, I.; Poindexter, C. M. ; Eichelmann, E.; Baldocchi, D. D.
Wetlands and flooded peatlands can sequester large amounts of carbon (C) and have high greenhouse gas mitigation potential. There is growing interest in financing wetland restoration using C markets; however, this requires careful accounting of both CO2 and CH4 exchange at the ecosystem scale. Here we present a new model, the PE…
