Determination of the origin of Austrian amphibians / reptiles
Thesis in the field of herpetology / conservation biology and phylogeography
Numerous species have strongly altered their distribution ranges in glacial-interglacial cycles. Thermophilic species have survived in so-called southern refuges and have then spread to the north again. During the relatively long-lasting isolation in southern refuges, new species and / or genetic lines have evolved that are still detectable over large parts of Europe and some regions, like parts of Austria, have hybrid zones.
In a phylogeographic thesis based on molecular markers (CO1, microsatellites), the biogeographic history of species such as the European Green Toad (Bufo viridis), the Grass Snake (Natrix natrix) or the Aesculapian Snake (Zamenis longissimus) should be clarified. For the former, or also for the Marsh Frogs (Pelophylax ridibundus) occurring in the alpine foothills, should be clarified whether their populations are allochthonous or autochthonous.
