Disentangling Effects Of Natural And Anthropogenic Drivers On Forest Net Ecosystem Production
Wang, Y., Buchmann, N., Hessen, D. O., Stordal, F., Erisman, J. W., Vollsnes, A. V., Andersen, T., Dolman, H.
Net Ecosystem Production (NEP) of forests is the net carbon dioxide (CO2) fluxes between land and the atmosphere due to forests’ biogeochemical processes. NEP varies with natural drivers such as precipitation, air temperature, solar radiation, plant functional type (PFT), and soil texture, which affect the gross primary produc…

The Impact Of Occasional Drought Periods On Vegetation Spread And Greenhouse Gas Exchange In Rewetted Fens
Koebsch, F., Gottschalk, P., Beyer, F., Wille, C., Jurasinski, G., Sachs, T.
Peatland rewetting aims at stopping the emissions of carbon dioxide (CO2) and establishing net carbon sinks. However, in times of global warming, restoration projects must increasingly deal with extreme events such as drought periods. Here, we evaluate the effect of the European summer drought 2018 on vegetation development and …

Recovering Evapotranspiration Trends From Biased CMIP5 Simulations And Sensitivity To Changing Climate Over North America
Sullivan, R. C., Kotamarthi, V. R., Feng, Y.
Future projections of evapotranspiration (ET) are of critical importance for agricultural and freshwater management and for predicting land–atmosphere feedbacks on the climate system. However, ET from phase 5 of the Coupled Model Intercomparison Project (CMIP5) simulations exhibits substantial biases, bolstering little confide…

Scaling and balancing carbon dioxide fluxes in a heterogeneous tundra ecosystem of the Lena River Delta
Rößger, N., Wille, C., Holl, D., Göckede, M., Kutzbach, L.
The current assessments of the carbon turnover in the Arctic tundra are subject to large uncertainties. This problem can (inter alia) be ascribed to both the general shortage of flux data from the vast and sparsely inhabited Arctic region, as well as the typically high spatiotemporal variability of carbon fluxes in tundra ecos…

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…
