Sažetak
The genus Campanula L. (Campanulaceae) includes about 400 species with highest diversity in the Mediterranean area. One of the morphologically and phylogenetically well established is the amphi-Adriatic group of nine endemic taxa belonging to the Campanula sect. Campanula ser. Garganicae Trinajstić. The taxa belonging to this group are: C. reatina Lucchese, C. garganica Ten., C. fenestrellata Feer subsp. fenestrellata, C. fenestrellata Feer subsp. istriaca (Feer) Damboldt, C. portenschlagiana Roem. & Schult., C. poscharskyana Degen, C. cephallenica Feer, C. acarnanica Damboldt, C. debarensis Rech. f., while the sister taxa to the group is C. comosiformis (Hayek & Janch.) Frajman & Schneew. Since all studied taxa inhabit unique karstic habitats, this kind of research is important for better understanding of complex biodiversity and endemism in this area as well as its more efficient protection. Recently several molecular phylogenetic studies confirmed the monophyly of the group and at the same time revealed poorly resolved relationships between taxa as well as conflicting relations between the nuclear ITS and chloroplast DNA sequences. Therefore, in this study additional populations were included. They were analysed comparing their nuclear ITS and chloroplast trnL-trnF DNA sequences. In addition, preliminary analysis of AFLP fingerprinting was performed on the population level in order to gain further insight on phylogenetic relationships within this group. The plastid and nuclear datasets were only partly congruent, possibly due to lineage sorting or hybridization. The AFLP data clearly separated all investigated taxa revealing some new lineages.
