EcoFun

Multi-scale studies of ecosystem functioning

The EcoFun team brings together expertise in functional ecology, ecophysiology, isotope geochemistry, remote sensing, biometeorology and ecohydrology. Our research aims to better understand the physiological responses and short and long term adaptation of terrestrial ecosystems to environmental changes, management practices and extreme climatic events. We are particularly interested in understanding how climate change will affect forest productivity, and more generally, water, CO2 and energy budgets at the Earth's surface.

For more information, see the team's website :  Ecosystem Functioning across scales

Doctoral students : Klara Bouwen (2021-2024), Thomas Guzmann (2019-2022), Xiaojun Li (2018-2022), Xiangzhuo Liu (2019-2023), Gaetan Noual (2019-2022), Tom Taborski (2019-2022), Huan Wang (2019-2023), Bertrand Ygorra (2019-2022)
