Projekte

Functional ecology of alpine meadows

The ongoing climate change has caused changes in the species composition of alpine meadows. Complementing the vegetation surveys realized in the GLORIA initiative, this project investigates the functional responses above- and belowground to abiotic drivers in alpine forb and grass species.

Soil and tree resilience after forest wildfire in Southern Italy

Pine tree stand and forest site resilience after the severe 2017 wildfire on the slopes of Vesuvius, Italy

The dynamic of ozone injury and responses within tree foliage

Relating the stress and detoxification responses at cell level to the phytotoxic ozone dose in foliage of trees

Metalink

Soil contamination with heavy metals is a widespread problem affecting natural, cultivated, urban and industrial sites throughout Europe. The main objective in this Swiss/Polish collaboration project is to characterize the links between environmental, genotypic, and phenotypic features in the metal-tolerant plant model Arabidopsis halleri.

Examining drivers of litter decomposition

Decomposition of plant litter is a key process for the transfer of carbon and nutrients in ecosystems. Carbon contained in the decaying biomass is released to the atmosphere as respired CO2, and may contribute to global warming. Litterbag studies have been used to improve our knowledge of the drivers of litter decomposition, but they lack comparability because litter quality is plant species-specific. The use of commercial tea bags as a standard substrate was suggested in order to harmonize studies, where green tea and rooibos represent more labile and more recalcitrant C compounds as surrogates of local litter.

CaNuPine/MICRO

In this project, adaptive and stress responses to drought stress and varying nutrient availability are being analyzed at tissue, cell and subcellular level in foliage of Scots pine and downy oak.

Compartmentation of de-icing salts and structural reactions to salt accumulation in foliage of ornamental lime trees

Street greenery has recently emerged as a major research and urbanization issue. The main objectives in this project are to study the accumulation and effects of de-icing salts in foliage of lime trees (Tilia x vulgaris) and to apply this knowledge for selecting more tolerant lime species and cultivars, with a view to street plantation.

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.

Antimony uptake as a function of waterlogging in the rhizosphere

Antimony (Sb) is a relatively rare element in the earth's crust, but mining, traffic, waste incineration and an increasing multitude of industrial uses have led to elevated levels in soils and sediments in many locations and consequently increased exposure of plants, animals and humans to this toxic element.

Evolutionary traits

The objective in this project is to characterize mechanistic aspects of metal accumulation and tolerance and relate it to the genetic structure of populations of Biscutella laevigata with varying genotypes, phenotypes, metal accumulation and tolerance.

Foliar symptoms specific for ozone stress in rain forest trees of southern Brazil

The toxic effects of tropospheric ozone concentrations on plants have been reported primarily for ecosystems from the northern hemisphere with a mediterranean, temperate or boreal climate. In the southern hemisphere with its tropical climate, the impact of ozone on natural ecosystems is still mostly unknown.

MICRO

Microscopical changes in cells and tissues in response to various environmental stress factors are investigated in trees to develop diagnosis tools and understand the mechanistic link between stress and injury.

Boron & salt allocation

Main objectives of this research project are to investigate the compartmentation-based mechanisms contributing to tolerance in foliage of poplar trees grown on soils contaminated with elevated levels of Boron and salts in the San Joaquin Valley in California.

Understory removal experiment Salgesch

Long-term research on the interactions between changes in land use and climate and their consequences regarding forest health and dynamic in the pine forests at low elevation of Central Alps

Macro- and micro morphological reactions to low soil water availability in the foliage of Scots pine from Wallis

In this project, the structural changes in foliage of Scots pine are used as sensitive bioindications of environmental constraints to study the reactions of dry pine forests in Wallis to low soil water availability and changes in land use.
