Progetti

Leaf temperature reconstruction

We critically lack leaf temperature assessments because of the difficulties associated with these measurements. The project aims at developing a novel approach that reconstructs leaf temperature over multiple time scales using plant water isotopes.

new multidisciplinary project on permafrost thaw

In this ambitious project, we study ecological effects of permafrost thaw

Abisko Long-Term Ecological Research ALTER

Setting up the ALTER experiment in Abisko, Sweden for non-destructive in situ monitoring of belowground vegetation and microbial dynamics.

Invasiveness of T. fortunei in the forests of southern Switzerland

The invasion of ecosystems by non-native species is one of the largest threats for biodiversity and ecosystem functioning worldwide. To control the spread of non-native plants, it is crucial to understand by which mechanisms they outperform native vegetation.

Polytunnel Greenhouse Experiment

Das Projekt untersucht, wie gut zukunftsfähige Baumarten während der Verjüngungsphase in einem Klima mit wärmeren Wintern und heiss-trockenen Sommermonaten wachsen, wie sie sich gegenseitig beeinflussen und welche Auswirkungen ihre Präsenz auf den Boden und die darin lebenden Organismen hat.

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?

PFF2020

Our main objective is the installation of a long-term Plant Physiological Facility for online determination of gas exchange and isotope fractionations at WSL in the 2020s.

Reconnaître les dendro-microhabitats: visite virtuelle immersive d'une forêt

Les dendro-microhabitats sont importants pour la biodiversité en forêt. Ce projet élabore un nouvel outil destiné aux gestionnaires forestiers, afin de les aider à identifier les dendro-microhabitats et connaître leurs rôles écologiques.

Root endophytic fungi and their contribution to arctic and alpine climate change feedback

Arctic and Alpine vegetation dynamics under climate change can exert a lasting impact on belowground processes and ultimately on world's largest carbon stocks. This long-term field manipulation investigates the functional significance of plant interactions with species-specific endophytic fungi.

Wie beeinflussen die Wechselwirkungen zwischen den Arten die langfristigen Auswirkungen von Hitze und Trockenheit

Ziel des Projektes ist es, die physiologischen Prozesse zu bewerten, durch die sich Bäume in einem sich ändernden Klima anpassen und miteinander interagieren, die Folgen dieser dynamischen Prozesse für die physiologischen Reaktionen der Bäume auf klimatische Belastungen zu bestimmen und unser Verständnis dieser Auswirkungen auf langfristige Verschiebungen im internen Kohlenstoff- und Wasserkreislauf der Bäume zu verbessern.

The role of mycorrhizae in soil carbon storage of mountain ecosystems

This research project focuses on the role of mycorrhizae in the turnover of soil organic carbon in mountain ecosystems. It estimates the potential release of greenhouse gases to the atmosphere resulting from changes in above and belowground communities.

Wälder im Klimastress

In this project we will assess the physiological processes by which trees adjust and interact among each other under a changing climate, determine the consequences of these processes on forest responses to climatic stresses and improve our understanding of these effects on forests functioning at a large comprehensive scale.

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.

Carbon and nutrient dynamics of Scots pine

In the CaNuPine project, we study the effects of drought and nutrient availability on the carbon dynamics within Pine (Pinus sylvestris) trees. This will contribute to the controversial debate whether drought may or may not cause acute growth decline and mortality via carbon starvation.

MOUNTROOT

The project MOUNTROOT aims at comparing structure-function relationship in roots of two dominant herb species of pasture-woodlands in response to simulated climate change, and to integrate these below-ground insights with above-ground responses to a whole-plant framework.

Dynamik von Totholz und xylobionten Insekten in Waldreservaten

Totholz ist Lebensgrundlage für rund einen Viertel aller Organismen im Wald. Die künftig wahrscheinliche Intensivierung der Holzwirtschaft wird viele holzbewohnende Insekten noch stärker gefährden. In diesem Projekt werden in Waldreservaten die Entstehung und der Abbau von Totholz quantifiziert, die Abhängigkeit von Insekten von Totholz untersucht und Mindestwerte für das Totholzangebot abgeleitet.

Mountland

Das Forschungsprojekt "Mountland" untersucht die möglichen Auswirkungen von potentiellen zukünftigen Klima- und Landnutzungsänderungen auf Ökosystemleistungen in Berggebieten. Das Projekt kombiniert in einem integrativen Vorgehen natur-, sozial- und politikwissenschaftlichen Methoden kombinieren, um Grundlagen für die Entwicklung von nachhaltigen Management- und Politikalternativen zu schaffen.
