Population genomics of fig wasp (Agaonidae) using genome-wide sequence data

The obligate mutualism of figs and fig pollinating wasps has been one of the classic models used for testing theories of coevolution and cospeciation due to the high species-specificity of these relationships. To investigate the species-specificity between figs and fig pollinators and to further understand the speciation process in obligate mutualisms, we examined the genetic differentiation and phylogenetic relationships of four closely related fig pollinating wasp species (Blastophaga nipponica, B. taiwanensis, B. tannoensis, and B. yeni) in Japan and Taiwan using genome-wide sequence data (ddRAD-seq).
