Sažetak
The Balkan Peninsula is one of the major European biodiversity hotspots and a known major glacial refugium for plant species. Its pronounced environmental heterogeneity coupled with relatively high climatic stability over long periods fostered diversification of lineages and enabled the long-term survival of diverse species. The increasing number of studied plant species in the region using modern molecular techniques have provided significant insights into intraspecific lineages, migration routes and locations of Pleistocene refugia. This presentation summarises the available phylogenetic and phylogeographic studies of plants from the Balkans that have revealed complex patterns in the geographic distribution of genetic diversity and challenged traditional taxonomic concepts. Here we will present the updated overview of the phylogeographical patterns and roles of refugia in structuring genetic diversity and highlight the crucial evolutionary processes that shaped the diversity of plants in the region. Molecular clock-based estimations highlight the importance of Pleistocene climatic fluctuations across taxonomic groups and lineage distribution patterns corroborate the persistence of multiple glacial refugia. Spatial congruences in phylogeographic splits are found and discussed. An examination of phylogeographic connections with adjacent regions i.e. Alps, Apennine Peninsula, Asia Minor, Carpathians and central Europe, also uncover several consistent patterns. Allopatric and adaptive speciation, polyploidy and hybridization are identified as crucial evolutionary mechanisms acting in the Balkan Peninsula and shaping species diversity. Finally, the scientific challenges are identified and the future research prospects with potential to better understand and conserve unique Balkan flora are highlighted.
