Conservation biology and biogeography

The research in my group focuses on conservation biology and biogeography of relict, endemic and threatened plants. Our main study and model taxa are woody plants with disjunct distribution pattern, with main interest on the genus Zelkova (Ulmaceae), Pterocarya (Juglandaceae) and Quercus (Fagaceae)

Additional interest touches the evolutionary processes, biogeographical patterns and conservation issues of aquatic and alpine plants, both at regional and global scale.

• Conservation of species, a key issue for our future

  We use various biogeographical, molecular and dendrochronological methods and are conducting intensive fieldwork in the Alps and adjacent mountain chains, in the Mediterranean (e.g., Crete, Sicily), in Transcaucasia (e.g., Georgia, Azerbaijan) and in Eastern Asia (e.g., China, Japan, Vietnam).

   

  Our group is closely connected to the Botanic Garden of the University of Fribourg (I am a director of the Garden) and is intensively collaborating with the Natural History Museum Fribourg (NHMF).

   

  Internationally, we are closely collaborating with the Shanghai Chenshan Botanic Garden (Shanghai Chenshan Plant Science Research Center, Chinese Academy of Sciences).
