Abstract:
A 903 bp section of the mitochondrial cytochrome b
gene was sequenced from 73 specimens of Podarcis melisellensis collected
at 52 localities distributed over the major part of the species' range. In
addition, parts of the 12S (about 470 bp) and 16S rRNA (about 500 bp) genes
were analysed for 11 representative samples leading to a congruent phylogeny.
Our study includes representatives of all 20 subspecies recognized today. The
phylogenetic analysis of the sequence data revealed three main clades: mainland
with nearby islands, Vis archipelago, and Lastovo archipelago. The degree of
mitochondrial DNA divergence among these clades suggests a separation of the
respective population groups during the earliest Pleistocene. The phylogenetic
pattern observed within the species is in sharp contrast to the actual
taxonomic division into subspecies. A correlation between genetic diversity of
P. melisellensis populations and paleogeography of the regions they
inhabit is discussed.
Key words: Podarcis melisellensis; phylogeography; subspecies; mitochondrial DNA
