How we work

What we do

The Alpine region is subject to exacerbated climate changes. Besides, alpine inland waters have long been under intense human exploitation, leading to disturbances in nutrient loadings, global or local pollutions, fishing activities and hydrological regulation for hydropower. Lakes in and around the Alps have been evolving in a context of continuous and intensifying environmental changes over the last 150 years, to which they are responding through non-linear and somewhat unpredictable trajectories.

Our team studies how lakes in and around the Alps have been responding to environmental changes. Our focus is on both biogeochemistry and ecology, covering different space and time perspectives.

We combine paleo-ecological reconstructions from sediment archives, high- and low frequency monitoring data, laboratory experiments and modeling to mechanistically unravel alpines lakes vulnerability and responses in a context of global change.
