First observation of facultative paedomorphosis in the Danube crested newt (Triturus dobrogicus Kiritzescu, 1903) and the occurrence of facultative paedomorphosis in two newt species from soda pans of the Danube-Tisza Interfluve (Kiskunság National Park, Hungary)
The first observation of paedomorphosis in Triturus dobrogicus and the occurrence of facultative
paedomorphosis in two newt species (T.dobrogicus and Lissotriton vulgaris) from soda pans of the Danube-
Tisza Interfluve, Hungary are reported in this paper. Facultative paedomorphosis in soda pans occurred in
2010, a year with extremely high precipitation. The favorable environmental conditions created enabled newt
populations to extend their aquatic life stage in otherwise unsuitable (too saline), though fish-free habitats. As
such, soda pans may provide a suitable aquatic environment for local newt populations in rainy years, and
facultative paedomorphosis may be an important adaptation allowing early reproduction in the following
year possible in an environment that frequently dries out
