| Abstract |
|
To examine phylogeny and geographie variation in Emys orbicularis a 1098 bp fragment of the mitochondrial cytochrome b gene was studied by a combined technique involving polymerase chain reaclion, DNA sequencing and RNA-heteroduplex analysis, Among 187 specimens 13 different haplotypes were idenlified, and Maximum Parsimony as weil as Neighbour Join)ng analyses found six major assemblages which corresponded to IberoMaghrebian, Tyrrhenian, southem ltalian, Adriatic, Central European-Balkan, and eastern Balkan populations. The phylogenetic clades could be attributed to putative glacial refugia located in southwestern Europe, ltaly, the Balkans, and the Ponticum. A remarkable extent of mixed mitochondrial populations occurs in the southeastern Balkans. Within the Central European-Balkan lineage northern populations differ from southern populations in small sequence alterations which can be linked to genetic drift. lt is suggested that territorial expansions from the Mediterranean refugia took place in the postglacial period.
