Tracing geographical patterns of population differentiation in a widespread mangrove gastropod: genetic and geometric morphometrics surveys along the eastern African coast




In the present study, we assessed the inter- and intrapopulation genetic and morphological variation of Cerithidea decollata along the eastern coast of Africa. The population structure of C. decollata along the latitudinal gradient was examined by sequencing 420 bp of the mitochondrial cytochrome c oxidase I (COI) gene in 172 snails from 29 sites, in a combined analysis with geometric morphometrics in 1799 snails from 32 sites. Analysis of molecular variance and spatial analysis of molecular variance showed a moderate spatial population differentiation from Kenya to the Republic of South Africa, suggesting genetic divergence between the northern, central, and southern regions.
