Response And Biophysical Regulation Of Carbon Dioxide Fluxes To Climate Variability And Anomaly In Contrasting Ecosystems In Northwestern Ohio, Usa
Chu, H., Chen, J., Gottgens, J. F., Desai, A. R., Ouyang, Z., Qian, S. S.

Recent climate variability and anomaly in the Great Lakes region provided a valuable opportunity in examining the response and regulation of ecosystem carbon cycling across different ecosystems. A simple Bayesian hierarchical model was developed and fitted against three-year (2011–2013) net ecosystem CO2 exchange (FCO2) data observed …

Ten-Year Variability In Ecosystem Water Use Efficiency In An Oak-Dominated Temperate Forest Under A Warming Climate
Xie, J., Chen, J., Sun, G., Zha, T., Yang, B., Chu, H., Liu, J., Wan, S., Zhou, C., Ma, H., Bourque, C. P., Shao, C., John, R., Ouyang, Z.

The impacts of extreme weather events on water–carbon (C) coupling and ecosystem-scale water use efficiency (WUE) over a long term are poorly understood. We analyzed the changes in ecosystem water use efficiency (WUE) from 10 years of eddy-covariance measurements (2004–2013) over an oak-dominated temperate forest in Ohio, USA. …

Representing Winter Wheat In The Community Land Model (Version 4.5)
Lu, Y., Williams, I. N., Bagley, J. E., Torn, M. S., Kueppers, L. M.

Winter wheat is a staple crop for global food security, and is the dominant vegetation cover for a significant fraction of Earth’s croplands. As such, it plays an important role in carbon cycling and land–atmosphere interactions in these key regions. Accurate simulation of winter wheat growth is not only crucial for future yield …

The Whole-Soil Carbon Flux In Response To Warming
Hicks Pries, C. E.; Castanha, C.; Porras, R. C.; Torn, M. S.

Soils contain about twice as much carbon as Earth’s atmosphere, so their response to warming is crucial to understanding carbon fluxes in a changing climate. Past studies have heated soil to a depth of 5 to 20 cm to examine such fluxes. Hicks Pries et al. heated the ground to a depth of 100 cm. Extending measurements to …

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 agricultural …

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 resource. …
