Study of color polymorphism and sexual dimorphism of pelophylax ridibundus sensulato (Ranidae: Anura) populations in the west and southwest of Kohgiluyeh Va Boyer-Ahmad province

Pelophylax ridibundus sensulato belongs to the family Ranidae. 56 specimens from Dishmook, Likak and Dehdasht areas were collected in spring and summer (2019-2020). Seven different morphs of this species were identified. The highest frequency was related to morph one. According to the analysis, the mean values and standard deviations of all morphometric characters of Dishmook' samples are higher  than the other two regions. Respect to t-test, sexual dimorphism was observed. Analysis of variance showed significant differences between the studied groups in both male and female frogs. Separation between male populations in all traits (except horizontal diameter of eye) was observed. Separation between female populations in all characters was also observed. Based on discriminant analysis, both functions were significant. Statistical results showed that frogs of Dishmook are somewhat different from the other two regions that can be related to different geographical conditions and higher altitude. Overall 84% of males and 87.1% of females were placed in their expected groups.
