Das Projekt "Biodiversität und Raumentwicklung" untersucht Zusammenhänge zwischen Biodiversität und Raumentwicklung auf Landschaftsebene. Dafür analysieren wir Daten des Schweizer Mittelands im Allgemeinen sowie der Kantone Aargau und Luzern im Speziellen für möglichst verschiedene Organismengruppen und unterschiedliche Aspekte der Biodiversität. Die Resultate werden kartographisch dargestellt und können zur Visualisierung von Szenarien der Landschaftsentwicklung eingesetzt werden.

Red lists are essential for an objective recording of the threat of species and changes in biodiversity. The accessory study of the revision of the red list of fern and vascular plants aims to evaluate the practicability of using statistical methods as a tool for revisions and quality control of red lists.

Within the cosmopolitan plant pathogenic species Phytophthora citricola, high levels of morphological and molecular variation were previously observed. Recently, DNA analyses revealed that the P. citricola complex actually includes four species, namely P. multivora, P. plurivora, P. citricola I, and P. citricola sensu strictu, which show different geographic distributions and host ranges.

Climate change is expected to affect the distribution and occurrence of breeding birds of mountain forests. In this study, we assess the direct and indirect effects of climate change on the realised ecological niches of habitat specialists of mountain forests by assessing key structural and vegetational habitat components along a climatic gradient.

The dispersal of several insect species occurring in fragmented habitats in the agricultural Swiss plateau will be investigated by using genetic methods and mark-recapture studies.

In this project we want to detect and describe factors that govern the evolution of virulence in the host–parasite interaction between Cryphonectria parasitica and Cryphonectria hypovirus 1 (CHV1). C. parasitica is an introduced fungus and causes the serious tree disease called chestnut blight. It can be biologically controlled by CHV1.

The main aim of this SNF-supported SINERGIA project is to characterize adaptive genetic diversity associated with environmental heterogeneity in natural populations of related plant species and to experimentally test the adaptive value of candidate loci under ecologically relevant environmental conditions

he regression of the distribution area in combination with a population decline is a common phenomenon of threatened wild animal species. Habitat deterioration and fragmentation of the natural or semi-natural landscape by human activities are often mentioned causes.
