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.

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.

BUKLIM – Macro- and micromorphological tolerance and stress reactions in foliage of beeches from marginal Swiss populations
BUKLIM – macro- and micro

As a consequence of global warming, European beech is threatened by habitat loss in central Europe. Within a sub-project of the Buklim experiment, macro- and micromorphological adaptations in foliage to drought stress are being analysed. Results should provide mechanistic insights on the adaptability of beech in a warmer climate.

Querco – Macro and micro-morphological reactions in foliage
Querco – macro and micro

Oaks are tolerant to drought stress and their present range in central Europe should increase, as a consequence of global warming. Within a sub-project of the Querco experiment, macroscopic and microscopic drought stress symptoms are investigated. Results should shed light on drought tolerance mechanisms within oak foliage.

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.

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

MODOEK - Modellökosystem-Anlage
MODOEK

Die Modellökosystemanlage (MODOEK) wurde 1992 gebaut und erstmals in Betrieb genommen. Zurzeit steht eine Modernisierung der Steuerung bevor. In der Anlage wurden seit 1992 mehrjährige interdisziplinäre Projekte erfolgreich durchgeführt.

MICRO – morphologische Bioindikationen von Umweltstress
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 and tolerance in foliage of salt-tolerant poplars from the California Central Valley
Boron & salt allocation

With a quickly growing world population and raising demand for agricultural products, the productivity of irrigated agricultural soils is threatened as a consequence of soil salinization in many places with arid climates. 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 Central California.

Macro- and micromorphological adaptations in pasture woodlands species from the Jura mountains in a warmer climate
Macro- and micromorphological adaptations

The pasture-woodlands in the Jura mountains are threatened by current global warming. In this project, macro- and micromorphological adaptations in herbs and tree species to simulated climate change are being analysed. Results should indicate how the plant species of pasture woodlands may adapt to climate change.
