Summary
Recent studies of the western Palearctic water frogs revealed the occurrence of at least 5 types of water frogs (Rana ridibunda, R. lessonae, R. perezi, 1 Italian and 1 Balkan species) as well as 4 types of their hybrids. In addition to the systematics, genetics and population compositions of these frogs, the complex mechanisms that lead to the production of the hybridogenetic hybridRana esculenta are emphasized, and the unsolved problems relating to the control of the hybridogenetic process are discussed.
