Abstract
The objective of this study is to determine the phenotypic plasticity among two populations of Stickleback (Gasterosteus aculeatus) from the Caspian Sea basin using landmark-based geometric morphometric method. A total of 101 specimens were sampled from two location of this basin including the Babolroud River (central part of the Caspian Sea basin) and the Gomishan wetland (east part of Caspian Sea basin). The left side of specimens was photographed using digital camera and 23 landmarks points were digitized on two- dimensional images using TpsDig2. Landmark data after generalised procrustes analysis (GPA) were analyzed using DFA and Manova. Results displayed significant difference of body shape between to studied population (P<0.001) that were related to body and head depth, caudal peduncle length and depth. These difference revealed morphological divergence related to habitat induced due to environmental parameters.
