1. Reproductive Biology and Evolution of the Tribe Exaceae (Gentianaceae)
Diplostigmaty, the presence of a primary (apical) stigma and secondary (mid-stylar) stigmas along the style is only known from the genus Sebaea (Gentianaceae). Early work indicated that the secondary stigmas provide a mechanism of autogamy suggesting that it may ensure reproductive assurance. We are using field and greenhouse experiments, as well as genetic marker, in order to determine the functional role of diplostigmaty and its evolutionnary implications.


The floral development of a few selected Sebaea species is also studied (together with P. K. Endress, University of Zürich), while we are investigating the role of several combinations of morphological characters as potential key-innovations within the tribe Exaceae (together with N. Salamin, University of Lausanne).

2. Hombori Project (Project Leader) 
In order to evaluate the respective impact of human and climatic factors on desertification, a multidisciplinary survey of Mount Hombori - one of the few remaining unspoiled zones of primary vegetation of Sahel - was started in 2003 (http://www.hombori.org).

Mount Hombori consists in an inaccessible tableland of about 2 square km located south of Timbuktu (Mali), at the border between the Sahara desert and the Sahel area. Due to the high cliffs surrounding its summit plateau, its flora and fauna have been preserved from pasture and agriculture. This ecological heaven is nowadays being threatened by the increasing pressure of tourism.

Fruit of an helvetico-malian collaboration, the first investigation of Mount Hombori biodiversity is now continued by a follow-up project including the completion of the starting biodiversity survey and its long-term monitoring to evaluate changes due to climatic factors. On the other hand, a sustainable protection and integrated development of the Mount Hombori region will be implemented.
