Abstract (German)

Saxifraga paniculata (Traubensteinbrech) und Sesleria albicans (Kalk-Blaugras) sind glaziale Reliktpflanzen, die aufgrund der klimatischen Erwärmung seit dem Ende des Pleistozäns heute wesentlich seltener sind und kleinere Populationen besitzen als während der letzten Eiszeit. Sesleria albicans besiedelt zudem Biotope, die sich hinsichtlich ökologischer Parameter sehr stark von einander ...

Translation of the abstract (English)

Saxifraga paniculata and Sesleria albicans are glacial relict plants. The present distribution of the two species is a result of the climatic changes after the last glaciation. Population size and range of Saxifraga and Sesleria were greatly reduced since the end of the pleistocene. Populations of Saxifraga and Sesleria were fragmented at least since the end of the last glaciation. Furthermore, ...
