Project Details


The genetic introgressive populations were detected in both native and introduced ranges of apple snails (Ampullariidea: Pomacea). However, the roles of introgressive hybridization played on invasion and evolution of Pomacea spp. were still unknown. Both the morphological and molecular evidences have indicated that P. occulta was probably specialized from the introgressive hybridization of both P. canaliculata and P. maculata. To test the hypothesis, we will analyze the effects of introgressive hybridization in specialization and evolution of apple snails based on genomics, molecular phylogenetics, and population genetics. Our results will enrich the theories of specialization and biological invasion, and provide the basis for understanding the invasion mechanisms as well as establishing effective prevention and control strategies against apple snails.
