A new study from the @EcofunTeam has been published in New Phytologist. The study shows that soil-stem water isotope offsets exist even in well-watered potted Fagus sylvatica saplings. We propose a new hypothesis to explain these isotopic offsets and provide
A new paper on beech forests’s ecophysiological response to droughts in current and future climate across Europe is available here. Congratulations to Fabio and Matthias for having pushed the limits of the model MuSICA by providing these Europe-wide model simulations.
In this paper, we propose a new model that relates C18OO photosynthetic discrimination ∆18O to carbonic anhydrase (CA) activity, in order to estimate mesophyll conductance (gm) in C3 and C4 plants. Newly ∆18O-derived gm values are usually close but significantly higher (typically 20% and up to 50%) than previous stimates assuming non-limiting CA
A new paper led by Feng Tian (University of Copenhagen) and Jean-Pierre Wigneron (Inra) and involving two members of the Ecofun team, reveals seasonal dynamics of plant water storage over the globe (using the microwave L-band vegetation optical depth SMOS-IC product) and
A new paper led by Adrià Barbeta is currently under review in Hydrology and Earth System Sciences discussion. In this paper, we investigated plant-water sources of an emblematic refugial population of Fagus sylvatica in the Ciron river gorges in South-Western France using stable isotopes.
It was really nice visiting Hans Schnyder’s wonderful lab and dynamic group in @TU_Muenchen. It was also a nice surprise to have Dan Yakir visiting at the same time. After an evening in the “oldest brewery in the world” (only
The EcoFun team invests Bordeaux Science Agro’s glasshouse this spring for an experiment investigating isotopic fractionation factors during root water uptake by Fagus sylvatica saplings. We took advantage of Julia Cook’s visit to show her the experiment and take a
A new paper led by Aurore Kaisermann is currently under review in Atmospheric Chemistry and Physics discussion. In this paper, we report carbonyl sulphide (COS) production and consumption rates in 27 European and Mediterranean soils and their biotic and abiotic drivers. Our main finding is
Sam’s new paper “non-destructive estimates of soil carbonic anhydrase activity and associated soil water oxygen isotope composition” is now published in Hydrology and Earth System Sciences. In this paper, we present a non-destructive method to retrieve simultaneously the soil carbonic anhydrase activity and
A new paper led by Samuel Jones is currently under review in Hydrology and Earth System Sciences discussion. In this paper, we present a non-destructive method to retrieve simultaneously the soil carbonic anhydrase activity and the oxygen isotopic composition of soil water that interacts
