The Parsley frog is represented by single species from Anatolia which is called Pelodytes caucasicus. This species is categorized as a near threatened in the conservation list and has very limited distribution along the North East Black Sea and its populations have been poorly studied. In this study, we analyzed morphological variation of 59 specimens from different localities from Anatolia (Artvin; Karagöl, Rize; Çat and Trabzon; Hıdırnebi) unraveled the differences among P. caucasicus populations. For this purpose, we used multivariate analysis such as principal component analysis (PCA) and linear discriminant analysis (LDA). Although there was considerable overlap among morphological variation of localities according to PCA analysis, slight differences were observed in LDA analysis. In PCA analysis, the HW, HL, and SVL are primarily discriminating characters for P. caucasicus. In LDA analysis, the NL, HW, and HL are primarily discriminating characters. This study will contribute to the limited data of P. caucasicus and enlarge the knowledge of geographic variation for P. caucasicus in Anatolia.

Türkiye’deki Pelodytes caucasicus Boulenger, 1896 (Anura: Pelodytidae) Türünün Morfolojik Çeşitliliği

Öz

Anadolu’da Pelodytidae familyasının Parsley kurbağası Pelodytes caucasicus adı ile bilinen tek türü dağılış göstermektedir. Bu tür koruma listelerine tehdite açık olarak kategorize edilir.Doğu Karadeniz boyunca kısıtlı yayılıma sahiptir ve populasyonları az çalışılmıştır. Bu çalışmada Anadolu’daki (Artvin; Karagöl, Rize; Çat ve Trabzon; Hıdırnebi) P. caucasicus populasyonları arasındaki farklılıkları ortaya çıkarmak için 59 bireyin morfolojik çeşitliliği analiz edilmiştir. Bu amaç doğrultusunda temel bileşenler analizi (PCA) ve doğrusal ayırım analizi (LDA) gibi çoklu analizler kullanılmıştır. Temel bileşenler analizinde lokaliteler arası çakışmalar gözüksede doğrusal ayırım analizinde az da olsa farklılık gözlenmiştir. Temel bileşenler analizine göre HW, HL ve SVL öncül ayırıcı karakterlerdir. Doğrusal ayırım analizine göre NL, HW ve HL öncül ayırıcı karakterlerdir. Bu çalışma P. caucasicus’un kısıtlı verisine katkı sağlayacak ve türün coğrafik varyasyonu ile ilgili bilgiyi genişletecektir.
