Aims of the study are to identify environmental variables underlying the mutual distribution of a species pair engaged in a long and winding hybrid zone, to reconstruct pattern and process of species’ range developments following the Last Glacial Maximum (LGM), and to open research lines for the study of hybrid zone dynamics in a model system.

Natrix astreptophora soumiafahdae subsp. nov. is very rare and has a fragmented distribution range. It represents an evolutionarily significant conservation unit for which conservation measures are needed. Leer más.
The aim of this Special Issue is to present new studies to advance our knowledge on demographic life-history traits in amphibians and reptiles as well as on the evolutionary diversification of aging and longevity in these vertebrates. Reviews and methodological contributions are welcome to be submitted. Leer más.
An analysis of the age structure of three water frog species (P. lessonae, P. ridibundus, P. esculentus) in the Middle Volga region of Russia was conducted. The skeletochronological method determined their maximum lifespans to be 7, 6, and 4 years, respectively. Leer más.
The age structure of amphibian populations plays an essential role in understanding population dynamics, potential impacts of environmental change, and conservation status. The Marsh frog Pelopyhlax ridibundus has become a subject of various studies to investigate age structure and body size variation. However, the populations living at high altitudes were paid less attention to while describing life history traits. Leer más.
