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 …

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 …

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 …

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 …

Annual greenhouse gas budget for a bog ecosystem undergoing restoration by rewetting
Lee, S.-C., Christen, A., Black, T.A., Johnson, M.S., Jassal, R.S., Ketler, R., Nesic, Z., Merkens, M.

Many peatlands have been drained and harvested for peat mining, agriculture, and other purposes, which has turned them from carbon (C) sinks into C emitters. Rewetting of disturbed peatlands facilitates their ecological recovery and may help them revert to carbon dioxide (CO2) sinks. However, rewetting may also cause substantial …

Evaluation Of Density Corrections To Methane Fluxes Measured By Open-Path Eddy Covariance Over Contrasting Landscapes
Chamberlain, S. D., Verfaillie, J., Eichelmann, E., Hemes, K. S., Baldocchi, D. D.

Corrections accounting for air density fluctuations due to heat and water vapour fluxes must be applied to the measurement of eddy-covariance fluxes when using open-path sensors. Experimental tests and ecosystem observations have demonstrated the important role density corrections play in accurately quantifying carbon dioxide ( CO …

Inter-Annual Variability Of Net And Gross Ecosystem Carbon Fluxes: A Review
Baldocchi, D., Chu, H., Reichstein, M.

As the lifetime of regional flux networks approach twenty years, there is a growing number of papers that have published long term records (5 years or more) of net carbon fluxes between ecosystems and the atmosphere. Unanswered questions from this body of work are: 1) how variable are carbon fluxes on a year to year basis?; 2) what …

Photosynthetic Responses To Temperature Across Leaf–Canopy–Ecosystem Scales: A 15-Year Study In A Californian Oak-Grass Savanna
Ma, S., Osuna, J. L., Verfaillie, J., Baldocchi, D. D.

Ecosystem CO2 fluxes measured with eddy-covariance techniques provide a new opportunity to retest functional responses of photosynthesis to abiotic factors at the ecosystem level, but examining the effects of one factor (e.g., temperature) on photosynthesis remains a challenge as other factors may confound under circumstances of …

The 2013 Flex—Us Airborne Campaign At The Parker Tract Loblolly Pine Plantation In North Carolina, Usa
Middleton, E., Rascher, U., Corp, L., Huemmrich, K., Cook, B., Noormets, A., Schickling, A., Pinto, F., Alonso, L., Damm, A., Guanter, L., Colombo, R., Campbell, P., Landis, D., Zhang, Q., Rossini, M., Schuettemeyer, D., Bianchi, R.

The first European Space Agency (ESA) and NASA collaboration in an airborne campaign to support ESA’s FLuorescence EXplorer (FLEX) mission was conducted in North Carolina, USA during September-October 2013 (FLEX-US 2013) at the Parker Tract Loblolly Pine (LP) Plantation (Plymouth, NC, USA). This campaign combined two unique airborne …

Direct And Indirect Climate Change Effects On Carbon Dioxide Fluxes In A Thawing Boreal Forest-Wetland Landscape
Helbig, M., Chasmer, L. E., Desai, A. R., Kljun, N., Quinton, W. L., Sonnentag, O.

In the sporadic permafrost zone of northwestern Canada, boreal forest carbon dioxide (CO2 ) fluxes will be altered directly by climate change through changing meteorological forcing and indirectly through changes in landscape functioning associated with thaw-induced collapse-scar bog (‘wetland’) expansion. However, their combined …
