MT180s: Laëtitia de Felix won the 2nd prize at U.Bordeaux

“My Thesis in 180 Seconds” is a competition in which participants are challenged to present their research topic in simple terms to a diverse, non-specialist audience. Each participant must deliver a clear, concise, and compelling three-minute presentation on their research project.
Out of 21 contestants, Laëtitia won the jury’s second prize and will compete in the regional finals on April 23.

TEMPO seminar

The LEAFPACE team participated in the TEMPO days from 13 to 17 October 2025, organised at the Meteo France site in Toulouse. Many interesting discussions took place on the state of the art in phenology research, during which Laëtitia and Juliette presented their work. Many thanks to the organisers for this week. Visit the TEMPO website to find out about all the network’s initiatives.

Second thermal camera installed at FR-Hes

We have installed the second site with a visible/IR camera in the Hesse forest (France), thanks to the invaluable help of Alwin Naiken, Pascal Courtois and Emilie Joetzjer. This installation will also support a new project by our colleagues at UMR INRAE SILVA, who will be installing sap flow and water potential sensors (florapulse) on trees (beech, oak) visible in the camera’s field of view.

Installation of our first thermal camera at FR-Fon

Our first thermal/visible prototype for monitoring leaf phenology and canopy temperature has been installed at the ICOS site in Fontainebleau, France. Many thanks to Daniel Berveiller for his help!Ten other sites will be installed by 2025.

Yesterday, we installed a new instrumental device dedicated to monitor the thermal properties of the forest canopy, in the context of the #LeafPace @erc.europa.eu project led by Marc Peaucelle from @inrae-france.bsky.social Several other devices in the next months on @icos-ri.eu forest sites.

Understanding the drivers of forest leaf phenology across scales

One of the main aims of LEAFPACE is to establish the links between the multiple processes controlling leaf phenology at organ, stand and regional level in the context of global change.
