Taxonomic Diversity of Vascular Plants in the European Alpine Areas

摘要: Using a relatively broad species concept, Flora Europaea describes about 11,500 native (Tutin et al.1964, 1968-1980). The richest areas are around the Alps, Pyrenees and Balkan Peninsula, where altitudinal zonation results in diverse habitats with many different or subspecies within small (Ozenda 1983; Lahti Lampinen 1999;Williams al. 2000). Although there have been previous attempts to understand relationships hence history of mountain systems Europe, comprehensive analysis by comparing ranges across Europe is difficult. distribution data compiled various local floras that use administrative political boundaries rather than natural biogeographical divisions. Moreover, workers at times, even similar areas, used concepts, thus making comparisons As new initiative, we examine here richness European alpine using from first 11 volumes Atlas Florae Europaeae (AFE). AFE (Jalas al.1996) provides individual maps for more 3000 vascular plant taxa Lycopodiaceae Brassicaceae, covering 20% all treated five Europaea. What makes this particular possible these digitised recently, enabling necessary diversity measures area-selection analyses WORLDMAP software (Humphries 1999;Lahti 1999; Williams al.2000).
