Biogeography & Phylogeography

In 2003, I completed my Ph.D. on the biogeography and phylogeography of the European alpine grasslands and especially those dominated by the sedge Carex curvula. I never completely gave up with this subject. Most of the following papers are about this story. There are other contributions that helped me broadening my views on plant community distribution, and not only grasslands ! A special thanks to Mihai Puscas, a former Ph.D. studient, now an invaluable friend and colleague, for past and ongoing collaborations on the biogeography of alpine grassands from the Pyrenees to the Carpatians.
