We will conduct a continental-scale climate sensitivity analysis of European beech and will investigate how different beech provenances differ in their climate growth response.
En prenant en compte les réponses évolutives basées sur les cernes des arbres, il sera possible de réduire les incertitudes relatives à la répartition spatiale des essences d'arbres européennes en fonction des scénarios de changement climatique.
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.
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.
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.
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.
This project aims to integrate the recording of standardized mast observation into existing phenology networks (e.g. PhaenoNet, Phenowald, PhenoRanger) and field surveys. The recorded data will be made publicly available on the already established platform of MastWeb hosted at WSL.
"PhenoRangers" a pour but d'établir des interactions entre les recherches actuelles sur l'impact des changements climatiques sur la forêt et le public, en utilisant la phénologie comme outil principal.
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.
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.
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.
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?
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.
