Multivariate analyses of nine call parameters demonstrate the existence of three distinct groups of populations which differ in the degree of temperature dependence of four parameters, and specifically in the number of pulses/pulse group and pulse groups/ call. Since discriminant functions distinguish among these groups with very low rates of false classification and since the degree of differentiation between the groups is similar to that towards R. perezi, taxonomic consequences are indicated.The lake frog populations near the Caspian Sea (CIS) inhabit the terra typica restricta and, thus, represent R. ridibunda. The lake frogs of Armenia (CIS) and of Thrace (Greece) also belong to this species. The mating call of R. ridibunda consists of 19 pulses/pulse group and of 7 pulse groups/call on the average. Finally, the southwestern form, inhabiting Greece and southern Yugoslavia, is named R. balcanica sp. n. Its mating call is characterized by 29 pulses/pulse group and 4 pulse groups/call on the average. Finally, the southeastern form ranging from Turkey to Egypt is named R. levantina sp. n. In this species the number of pulses/pulse group averages 11 and that of pulse groups/call 10. According to the phylogenetic analysis of the character states using parsimony, we conclude that R. perezi and R. levantina are sibling species forming an outgroup to the European sibling species R. ridibunda and R. balcanica.}, keywords = {Amphibia, Anura, Genetic differentiation, marsh frog, multivariate statistics, PHYLOGENETIC-RELATIONSHIPS, phylogeny, populations, rana-ridibunda, Ranidae, taxonomy, territorial calls, tree frogs, vocalization, water frogs}, author = {Schneider, H. and Sinsch, U.} } @article {11574, title = {Taxonomic reassessment of Middle Eastern water frogs: Bioacoustic variation among populations considered as Rana ridibunda, R. bedriagae or R. levantina}, journal = {Journal of Zoological Systematics and Evolutionary ResearchJournal of Zoological Systematics and Evolutionary Research}, volume = {37}, number = {2}, year = {1999}, note = {Cited By (since 1996): 13Export Date: 6 September 2006Source: ScopusReferences: Akef, M.S.A., Schneider, H., The eastern form of Rana ridibunda (Anura: Ranidae) inhabits the Nile delta (1989) Zool.

The populations of Thrace and of the island of Samothraki form a group giving the same type of mating call, whereas the mating call of the other populations differs in the degree of temperature dependence of four parameters, and specifically in the number of pulses/pulse group and pulse groups/call. Discriminant functions distinguish even single call series with a probability of 97 \%, intermediate mating calls are absent, and there is a significant, but slight differentiation of external morphological characters. These results have strong taxonomic implications. We conclude that the lake frogs of Greece comprise two species.The mating call of the lake frogs from Thrace resembles in all parameters that of the Rana ridibunda in the terra typica restricta (Guryev CIS). Accordingly, the lake frogs of eastern Greece belong to R. ridibunda. The mating call of these lake frogs consists of 20 pulses/pulse group and of 7 pulse groups/call on the average. Most of Greece is inhabited by the second taxon, Rana balcanica sp. n. Its mating call is characterized by 27 pulses/pulse group and 4 pulse groups/call on the average.The two species in Greece do not differ with respect to coloration and size, but several standardized indices vary significantly: body length/digitus primus length; body length/callus internus length; body length/snout-eye distance; body length/tympanum diameter; tibia length/callus internus length; maximal head width/snout-eye distance.}, keywords = {Amphibia, Anura, behavior, external morphology, israeli, mating call, multivariate statistics, northern Greece, populations, rana-balcanica sp-n, rana-ridibunda, Ranidae, species description, taxonomy, toad, vocalization}, author = {Schneider, H. and Sinsch, U. and Sofianidou, T.
