We investigated the recent evolutionary history of the Danube crested
newt, Triturus dobrogicus through reconstructions of: (1) the number and
position of refugia at the last glacial maximum, (2) the role of major
central European rivers in pattern of post-glacial dispersal, and (3) the
present-day distribution pattern. We analysed sequences of mitochondrial
DNA (ND2, 1065 bp) and six microsatellite loci in 363 T. dobrogicus
individuals from 58 populations covering the range of the species. Our
analyses suggested that T. dobrogicus survived the last glacial maximum in
two separate refugia positioned in northwestern Pannonia and in Southern
Pannonia from where its range expanded along the Danube and Tisza Rivers.
Our findings also confirmed that rivers played an important role in
shaping the evolutionary history of amphibian species in Central Europe.
We compared the T. dobrogicus range with another lowland amphibian, the
fire-bellied toad Bombina bombina, using species distribution modelling.
In line with these models, the isolated mountains inside Pannonia are
occupied not by B. bombina, but by its mountain-dwelling sister-species B.
variegata. However, in contrast to the model, crested newts (including T.
dobrogicus) are absent from these mountains. We attribute this
biogeographical discrepancy to the positioning of the species’ refugia at
the last glacial maximum.
