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.
A few years ago, I was writing an application to come and join the EcoFun team in the middle of a gas-exchange measurement campaign. The trees had flushed right before we started the campaign and on the first day of
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.
One of the expected effects of rising atmospheric CO2 concentration in the atmosphere is an increase in plant water use efficiency due to reduced transpiration at the leaf level. Yet, this prediction is based mostly on retrospective analyses of how
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
Last August, Functional Plant Biology published online our paper on the effects of soil water and temperature on light inhibition in Mediterranean holm oak forests. There is a long story behind how two ECOFUN members ended up contributing to this
