Past genetic diversity of Swiss mountain forests

Future climate change will have drastic effects on mountain forests. We will analyse ancient DNA preserved in natural archives to reconstruct the impact of past rapid climate change on the neutral and adaptive genetic diversity of trees.

Modèles d'invasion biologique et dynamiques de croissance des frênes

En Europe, le dépérissement des pousses du frêne causé par Hymenoscyphus fraxineus a entraîné un taux de mortalité élevé chez les frênes communs. Nous analysons comment la croissance radiale et les paramètres anatomiques du bois influencent la progression de la maladie dans les arbres.

Adaptation of trees to extreme climate events

Extreme climate events are expected to become more frequent with climate warming. We test genetic differentiation in resistance to late frost and drought in silver fir populations planted in the 1980s in Swizterland and abroad.

QUPFIS

Our aim is to estimate Swiss forest net ecosystem productivity (NEP) at monthly or seasonal resolution for each individual year in order to link biomass changes over time with global drivers.

Phenological synchrony between soil microbes, nutrient availability, trees leaf-out and moths

The synchronization between supply and demand of resources in temperate forests is vital to ensure the optimal and sustainable functioning of these ecosystems. This project aims to understand how global warming is disrupting interactions between above- and below-ground organisms.

Sécheresse et hêtres: effets à moyen terme de la sécheresse estivale de 2018 sur le hêtre sur le versant nord des Alpes

Dans ce projet, nous étudions les causes des impacts de l'extrême sécheresse de l'été 2018 sur la vitalité des hêtres dans différentes régions du Plateau suisse et du Jura.

eLTER Switzerland

The Long-Term Ecologiocal Research in Europe (LTER-Europe) capitalizes on research infrastructures such as the in-situ network of sites and information technology. Thousands of research projects have been carried out taking advantage of this infrastructure.

Acclimation and environmental memory

Which are the main mechanisms conveying adaptation on the organ and whole tree level, how fast does acclimation occur and how long is an acclimation potential sustained?

PRO3FILE

To improve our assessment of ozone effects on forest ecosystems, we advocate the need (i) for further experimental and long-term monitoring studies and (ii) to develop physiological and demographic modelling tools.
