Phylogeography and acquisition of dioecy in Malvaceae


In the Mascarenes, a young oceanic archipelago, the Dombeyoideae have extens­ively diver­si­fied and have evolved spe­cific breed­ing sys­tems com­pared to the con­tin­ental spe­cies. By con­struct­ing a molecu­lar phylo­geny, Le Péchon et al. (pp. 343–357) show that the diversity of the Mascarene’s Dombeyoideae is the res­ult of four inde­pend­ent col­on­iz­a­tions from Madagascar and that dioecy is an evol­u­tion­ary con­ver­gence that may be the con­sequence of select­ive pres­sure par­tic­u­lar to oceanic island environments.
