| Title | Genetic variability and phylogeography of the cyprinid Telestes muticellus within the Italian peninsula as revealed by mitochondrial DNA |
| Abstract | A phylogeographic analysis of 12 populations of Telestes mulicellus was performed on the basis of mitochondrial DNA sequences of the cytochrome h gene. The main aims were to determine phylogenetic relationships from congener species and to highlight the patterns of genetic differentiation within the Italian peninsula. The results obtained showed a significant divergence with the congener species, indicating a possible Miocene origin for the genus. Divergence was found to be low for T. muticellus, yet distinct lineages resulted as being allopatric within the two main Italian biogeographic districts, the Padano-Venetian and the Tuscano-Latium, suggesting the existence of recent vicariance coupled with past demographic regression. The high level of genetic differentiation found between populations highlighted the low dispersal ability of this rheophilic Cyprinid, whose migration was mainly related to connections between the upper parts of river basins. The distribution of sequence characteristics found suggests that particular attention should be paid to the conservation management of this species. |
