CaNuPine/MICRO – Micromorphological changes within foliage of two xerophytes in response to varying water and nutrient availability
CaNuPine/MICRO

As a consequence of ongoing climate change, elevated drought stress and higher rates of mortality have been observed for the last 20 years in e.g. Switzerland, especially in the low elevation pine stands of Central Wallis. Within a sub-project of the CaNuPine experiment, 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. The expected findings should provide insights of morphological and physiological adaptation specificities in these two drought-tolerant xerophytes.

Metalink - Linking environmental, genomic and phenotypic adaptation to study the adaptation of Arabidopsis halleri to metal polluted soils
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. Using phenotypic characterization and whole genome re-sequencing at the population level, the responses of plants as a function of their genetic background are analyzed in the framework of a reciprocal transplant experiment realized at industrial and strongly polluted versus unpolluted sites in Southern Poland. The expected results should provide the scientific basis for deciphering metal-tolerance and accumulation mechanisms at the level of single genes or gene networks.

TEA-Electrical potentials and accoustic emissions of trees
TEA-Electrical potentials and accoustic emissions of trees

TEA combines established methods in ecophysiology (i.e., measuring sap flow, detecting continuous stem radius changes, and recording the microclimatic conditions) with advanced methods of measuring ultrasonic acoustic emissions (UAEs) and detecting electrophysiological signals, so-called electrical potentials (EPs).

CaNuPine – Physiological coupling mechanisms of carbon and nutrient dynamics underlying the drought-induced decline of Scots pine
CaNuPine – Physiological coupling mechanisms of carbon and nutrient dynamics underlying the drought-induced decline 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.

Compartmentation of de-icing salts and structural reactions to salt accumulation in foliage of ornamental lime trees
Antimony uptake as a function of waterlogging in the rhizosphere

Street greenery, as a way of mitigating pollution problems in cities and providing the inhabitants with different sorts of ecosystem services, 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. The expected results should provide mechanistic insights on salt allocation and injury and better understanding of possible tolerance mechanisms, with a view to selecting more resistant ornamental lime trees.

Antimony uptake as a function of waterlogging in the rhizosphere
Antimony uptake as a function of waterlogging in the rhizosphere

Antimony (Sb) is a rather rare but toxic element increasingly contaminating ecosystems. Principal objectives in this project are to investigate the role of changes in the soil conditions and root structure on the uptake of Sb. The results will provide understanding of the soil and root processes governing Sb availability and plant uptake.

Disentangling truffle ecology
Disentangling truffle ecology

We study the complex biotic and abiotic ecology and the population genetics of the Burgundy truffle (Tuber aestivum) in Switzerland and the German pre-Alps, with particular emphasis on the ecological and climatological drivers for the productivity and phenology of this most valuable truffle species.

Pilzreservat La Chanéaz: Langzeitmonitoring zur Erforschung von Wachstum und Phänologie von Waldpilzen
Pilzreservat La Chanéaz

Das Pilzreservat La Chanéaz ist national wie international einzigartig. Nirgendswo auf der Welt wurde bisher über einen so langen Zeitraum die Entwicklung der Pilzflora untersucht. Auch die räumliche und zeitliche Auflösung der Datenerhebung ist einmalig.

Physiological mechanisms underlying the dynamics of the upper limit of different life forms under climate change
Physiological mechanisms underlying the dynamics of the upper limit of different life forms under climate change

Climatic high-elevation boundaries of vegetation occur over a wide range of latitudes from 55°S to 70°N. No studies compared the physiological mechanisms underlying formation of the upper limit of different life forms (e.g. trees, shrubs, and herbs), and hence, a conclusive functional explanation of the formation of these lines is still awaited.
