Towards physiologically meaningful water‐use efficiency estimates from eddy covariance data
Juergen Knauer, Soenke Zaehle, Belinda E. Medlyn, Markus Reichstein, Christopher A. Williams, Mirco Migliavacca, Martin G. De Kauwe, Christiane Werner, Claudia Keitel, Pasi Kolari, Jean-Marc Limousin, Maj-Lena Linderson
Intrinsic water‐use efficiency (iWUE) characterizes the physiological control on the simultaneous exchange of water and carbon dioxide in terrestrial ecosystems. Knowledge of iWUE is commonly gained from leaf‐level gas exchange measurements, which are inevitably restricted in their spatial and temporal coverage. Flux measure…

Improved Spatiotemporal Representativeness and Bias Reduction of Satellite‐Based Evapotranspiration Retrievals via Use of In Situ Meteorology and Constrained Canopy Surface Resistance
Sullivan, R. C., Cook, D. R., Ghate, V. P., Kotamarthi, V. R., Feng, Y.
Evapotranspiration (ET) is a key component of the atmospheric and terrestrial water and energy budgets. Satellite‐based vegetation index approaches have used remotely sensed vegetation and reanalysis meteorological properties with surface energy balance models to estimate global ET (MOD16 ET). We reconstructed satellite retrie…

Habitat fragmentation is linked to cascading effects on soil functioning and CO2 emissions in Mediterranean holm-oak-forests
Flores-Rentería, D., Rincón, A., Morán-López, T., Hereş, A-M., Pérez-Izquierdo, L., Valladares, F., Curiel Yuste, J.
We studied key mechanisms and drivers of soil functioning by analyzing soil respiration and enzymatic activity in Mediterranean holm oak forest fragments with different influence of the agricultural matrix. For this, structural equation models (SEM) were built including data on soil abiotic (moisture, temperature, organic matter…

Cascading effects associated with climate-change-induced conifer mortality in mountain temperate forests result in hot-spots of soil CO2 emissions
Curiel Yuste, J, Flores-Rentería, D, García-Angulo, D, Hereş, A-M, Bragă, C., Petritan, A-M, Petritan, IC
Climate change-induced tree mortality is occurring worldwide, at increasingly larger scales and with increasing frequency. How climate change-induced tree mortality could affect the ecology and carbon (C) sink capacity of soils remains unknown. This study investigated regional-scale drought-induced tree mortality, based on event…

Methane and carbon dioxide fluxes over a lake: comparison between eddy covariance, floating chambers and boundary layer method
Erkkilä, K-M., Ojala, A., Bastviken, D., Biermann, T., Heiskanen, J.J., Lindroth, A., Peltola, O., Rantakari, M., Vesala, T., Mammarella, I.
Freshwaters bring a notable contribution to the global carbon budget by emitting both carbon dioxide (CO2) and methane (CH4) to the atmosphere. Global estimates of freshwater emissions traditionally use a wind-speed-based gas transfer velocity, kCC (introduced by Cole and Caraco, 1998), for calculating diffusive flux with the bo…
