Sažetak
Delimiting species only on morphology may lead to taxonomic inflation, biasing conservation studies and actions, particularly in organisms recently diversified. For instance, the central Mediterranean Dianthus virgineus L. complex belongs to a lineage that evolved rapidly in Eurasia, and is characterized by high phenotypic variation. In the central Mediterranean, 21 taxa are currently accepted, albeit solely described according to qualitative morphological and phenological variation. Our objective is to apply an integrative taxonomic approach, including morphometry, karyology, and genetics, to test these taxonomic hypotheses. We genotyped thousands of genome-wide biallelic, unlinked SNPs from 123 populations from southern France, peninsular Italy, Corsica, Sardinia, and Sicily, through ddRAD sequencing and conducted an explorative PCA and STRUCTURE analysis to detect genetic differentiation. All across the study area there is an overall low genetic variability, albeit structured according to geographical distribution of populations. In particular, we detected a NW-SE cline from southern France to Calabria, and a second, orthogonal cline from central Italy to Sardinia through the Tuscan Archipelago and Corsica. Conversely, plants from Sicily form a genetic cluster that does not appear to follow clinal patterns recovered in the Italian Peninsula. We deduce that the number of genetically recognizable groups of the D. virgineus complex in central Mediterranean is much lower than the current taxonomic hypotheses, highlighting the importance of an integrative taxonomic approach to better circumscribe systematic units. However, taxonomic conclusions await thorough morphometric and karyological analyses, which are currently underway.
