Abstract: (9 Views) |
This study examined morphological differentiation among seven populations of Sasanidus kermanshahensis within the Karkheh River drainage using a geometric morphometric approach. A total of 89 specimens were collected from the Khorram, Maran, Gerdkaneh, Boujin, Sartang, Dinorab, and Doab Rivers. The left lateral view of each specimen was photographed, and 16 homologous landmarks were digitized using tpsDig2. Landmark configurations were subjected to Generalized Procrustes Analysis, followed by multivariate analyses including Principal Component Analysis (PCA), Canonical Variate Analysis (CVA), and Cluster Analysis (CA). Significant shape differences were detected among populations (P < 0.05), primarily associated with body depth, mouth position, anal-fin region, and caudal-peduncle depth.
