Welcome to the LEF!

Our vision is to advance the understanding, predicting, and mitigating climate change and biodiversity loss in natural and agricultural ecosystems. We focus on the complex relationships between plants, microbes, invertebrates, and vertebrates in the soil and above ground. We aim to deepen our understanding of these interactions through a combination of conceptual and experimental research, ranging from evolutionary adaptations to community dynamics and ecosystem processes. Our ultimate goal is to apply this knowledge to promote the sustainability of life on Earth.

We aim to address several unanswered questions concerning:

  • The ecology and evolution of species interaction, with particular emphasis on plant-herbivore-predator interaction, community ecology along climatic gradients, and eco-metabolomics research

 

  • Soil sciences, including aspects of soil formation (pedogenesis), soil ecology, humus forms, soil organisms, and organic matter recycling

 

  • Agroecology, in particular, pest control through plant defense mechanisms and plant-microorganism interactions. In addition, our laboratory has established an international partnership with the Institute of Environmental Processes and Pollution Control (Jiangnan University, China) to study the beneficial effects of modified nanoparticles on crop yield and pest control.

 

  • Conservation biology, with a particular focus on conservation approaches that combine monitoring and species interactions.

January 2026 – New publication

Congratulations to Stéphanie Morelon on the publication of their article in Journal of Biogeography:
Metabolomic divergence in the alpine Primula auricula complex

This study uncovers clear phylogenetic and environmental structuring of metabolomic profiles in Primula auricula, highlighting valuable cryptic diversity for taxonomy and conservation.

A sunny November day, a cozy fondue lunch, and great company!
We enjoyed delicious melted cheese outdoors, shared laughter, and made the most of the unexpected autumn sunshine.

We marked LEF’s 10th anniversary with a memorable day at La Sauge!
The celebration included a scenic hike, a delicious wild boar roasted on a spit, and plenty of great moments shared over fine wine.

New podcast episode – Plant communication revealed

Discover how some tomato plants can warn their neighbors of danger!
In this interview, Sergio Rasmann, Professor of Plant Ecology at the University of Neuchâtel, explains how plants use chemical signals to defend themselves and communicate.

A fascinating dive into the hidden language of plants. 🌱✨
