The aim of this study was to identify a reliable set of quantitative and qualitative morphological characters that objectivelyresolve species’ identification in the Pelophylax esculentus complex and provide a rapid and robust procedure for taxon identification.Our results showed a substantial difference in morphological characteristics among taxa.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Methods for morphological identification of water frogs from the Pelophylax esculentus complex have changed over the decades.Still, without resort to genetic analyses, water frogs remain among the most difficult European amphibians to distinguish due to theirhybrid nature.

Abstract

Methods for morphological identification of water frogs from the Pelophylax esculentus complex have changed over the decades.Still, without resort to genetic analyses, water frogs remain among the most difficult European amphibians to distinguish due to theirhybrid nature. The aim of this study was to identify a reliable set of quantitative and qualitative morphological characters that objectivelyresolve species’ identification in the Pelophylax esculentus complex and provide a rapid and robust procedure for taxon identification.Our results showed a substantial difference in morphological characteristics among taxa. The shape and size of the metatarsal tuberclealong with the coloration of the hind limbs and flanks appear to be the most important diagnostic traits. Linear discriminant analysiswith both quantitative and qualitative traits as a rapid method for the assessment of water frog taxa showed satisfactory accuracy andprediction classification for all 3 members of the complex.
