Colonization and diversification of the Euphorbia species (sect. Aphyllis subsect. Macaronesicae) on the Canary Islands.

ABSTRACT: Diversification between islands and ecological radiation within islands are postulated to have occurred in the Euphorbia species (sect. Aphyllis subsect. Macaronesicae) on the Canary Islands. In this study, the biogeographical pattern of 11 species of subsect. Macaronesicae and the genetic differentiation among five species were investigated to distinguish the potential mode and mechanism of diversification and speciation. The biogeographical patterns and genetic structure were examined using statistical dispersal-vicariance analysis, Bayesian phylogenetic analysis, reduced median-joining haplotype network analysis, and discriminant analysis of principal components. The gene flow between related species was evaluated with an isolation-with-migration model. The ancestral range of the specie
