Taxonomic reassessment of Middle Eastern water frogs: Morphological variation among populations considered as Rana ridibunda, R. bedriagae or R. levantina

, : Taxonomic reassessment of Middle Eastern water frogs: Morphological variation among populations considered as Rana ridibunda, R. bedriagae or R. levantina. Journal of Zoological Systematics & Evolutionary Research 37(2): 67-73, June

Eight morphometric features of water frogs of 14 localities in Turkey, Syria, Jordan and Israel were compared with those of Rana ridibunda in Kazakhstan, Armenia and Greece (Thrace). These study sites include the type localities of R. ridibunda, R. r. caralitana, R. esculenta var. bedriagae and R. levantina. Multivariate comparisons (principal-component analysis, discriminant analysis) based on the log10-transformed variables demonstrate that the data set includes only two taxa that differ significantly in size and shape. By applying a morphospecies criterion, R. ridibunda is represented exclusively by the three reference populations, whereas all other populations (in Turkey, Syria, Jordan and Israel) represent the same species, R. bedriagae.
