Congratulations to Regina for her new paper that takes the MuSICA model to a new level by exploring the physiological and climatological signals recorded in the cellulose 18O/16O ratio of grasses. Using a new carbon growth and allocation scheme specific to grasslands, she demonstrated
Petit article (en français) publié par @EcofunTeam pour la #FêteDeLaScience sur les microclimats en forêt via @FR_Conversation: Climat, espèces et adaptation : le rôle de la gestion forestière. Les sous-bois jouent un rôle essentiel pour l’adaptation des espèces au changement de température, mais les pratiques
A new paper led by Sam Jones is currently under review in SOIL discussions. In this paper, we investigated the drivers of soil water-CO2 isotopic exchange across biomes and land use types in order to better represent this huge flux in
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
