Über die Letalität und Hybridogenese beim Rana esculenta-Komplex
Revue suisse de zoologie
Concerning the lethality and hybridogenesis in Rana esculenta complex. -Numerous studies of the European green frogs have demonstrated that Rana ridibunda and Rana lessonae are two distinct species, whereas Rana esculenta represents their hybrid (see references in Berger 1982) . In order to understand the complex phenomena of lethality and hybridogenesis in R. esculenta further crossing experiments between these three green frog phenotypes have been carried out by us.
