O 09 Phylogeny and biogeography of selected plant groups from the Balkan Peninsula Božo Frajman 1 & Peter Schönswetter 2 1 Biology Department, Biotechnical Faculty, University of Ljubljana, Večna pot 111, SI- 1000 Ljubljana, Slovenia. E-mail: bozo.frajman@bf.uni-lj.si 2 Department of Biogeography and Botanical Garden, University of Vienna, Rennweg 14, A-1030 Vienna, Austria. E-mail: peter.schoenswetter@univie.ac.at The Balkan Peninsula is renowned for its biodiversity and high levels of endemism both among animals and plants. Still, biota of some parts of the Balkans ranges among the least known in Europe. Studies using modern molecular approaches are largely lacking, with the exception of some recent phylogenetic and phylogeographic studies. One of the genera with several endemics described from the Balkans is Heliosperma (Sileneae, Caryophyllaceae). Phylogenetic and phylogeographic studies using chloroplast and nuclear DNA sequences as well as AFLP data suggest complex reticulate patterns and molecular data do not support traditional taxonomic delimitations within the H. pusillum group. Chloroplast data suggest an old split within the group, which is geographically correlated. This is not supported by nuclear data, possibly due to hybridisation between the two groups. Molecular dating suggests a recent, most probably Pliocene/Pleistocene diversification within the group. On the contrary, H. macranthum from Montenegro/Albania/Kosovo, is likely of more ancient Tertiary origin. The general assumption that many Balkan endemics are Tertiary relics has thus to be taken with caution. Another plant group including several Balkan endemics is the Euphorbia barrelieri group. Phylogenetic studies using nuclear and chloroplast DNA sequences reveal patterns different from traditional classifications. ITS data suggest that Euphorbia barrelieri from Italy is not most closely related to E. barrelieri from the Balkan Peninsula. Euphorbia nicaeensis and E. glareosa are nested within this group and E. herzegovina is most closely related to E. nicaeensis. Euphorbia kerneri and E. triflora are most closely related, whereas E. saxatilis from the Eastern Alps forms an independent lineage. Additional sampling is needed to corroborate these preliminary results. 10
O 10 Phytogeographical relationships of high-mountain flora in the Carpathians Zbigniew Mirek 1 , Gheorge Coldea 2 , Roman Letz 3 , Karol Marhold 3,4 , Halina Piękoś- Mirkowa 5 1 Institute of Botany, Polish Academy of Sciences, Lubicz 46, PL-31-512 Kraków, Poland; 2 Institute of Biological Research, Strada Republicii 48, RO-3400 Cluj- Napoca, Romania; 3 Institute of Botany, Slovak Academy of Sciences, Dúbravská cesta 14, SK-845 23 Bratislava, Slovak Republic; 4 Department of Botany, Charles University, Benátská 2, CZ-128 01 Praha 2, Czech Republic; 5 Institute of Nature Conservation Polish Academy of Sciences, Al. Mickiewicza 33, PL-31-120 Kraków, Poland. Based on distribution of high mountain vascular plant species in the Carpathians most important phytogeographical phenomena are characterised and discussed relying on multi-varied numerical analyses. These include: ‐ patterns of distribution discernible within high mountain flora of the Carpathians in relation to main phytogeographical elements, ‐ endemism, with special concern to categories of endemic species, ‐ division of the Carpathians into natural phytogeographical units and floristic entity of these units reflected in distinctiveness of high mountain flora, ‐ evident floristic gap and conspicuous differences between western and southeastern Carpathians, ‐ clear gaps between eastern and southern parts of the Carpathians with some other floristic discontinuities found among these two parts; apart of that gradual changes along the arch of the Carpathians from South to the North and from East to the West have been observed. Some general relationships with high mountain flora with Alps are drawn. 11
