geographical clinal intraspecific variation morphology Odorrana margaretae
The green odorous frog (Odorrana margaretae) has an interesting ring-shaped divergence pattern around the Sichuan Basin and ing its morphological variations is essential in understanding its evolutionary history. Using curvilinear models, we detected significant geographical clinal variations in morphological traits, particularly sizes, of female O. margaretae. Males had significantly smaller sizes than females, and also had smaller variation ranges than females. One major trend of morphological variations was clinal: populations from the west tended to have a larger size with wider head and longer posterior limbs than populations from the east. Species history, with an early extended isolation and two subsequent secondary contacts, may explain most of the geographical clinal variations of O. margaretae. Bioclimatic factors may also contribute in explaining the variance of morphology.
