Fig. 6From: Population genomics of an exceptional hybridogenetic system of Pelophylax water frogsPCA on morphometric data combining all three species found in Ticino (top), P. lessonae with P. kl. esculentus (middle), and P. kl. esculentus only (bottom). Color and symbols discriminate geographic origin (dark blue: northern Ticino; light blue: southern Ticino) and species (squares: P. ridibundus; circles: P. lessonae; triangles: P. kl. esculentus)Back to article page
