@ARTICLE{TreeBASE2Ref17258, author = {Nina R?nsted and Gabriele Salvo and Vincent Savolainen}, title = {Biogeographical and phylogenetic origins of African fig species (Ficus section Galoglychia)}, year = {2006}, keywords = {}, doi = {}, url = {}, pmid = {}, journal = {Molecular Phylogenetics and Evolution}, volume = {}, number = {}, pages = {}, abstract = {Ficus section Galoglychia (subgenus Urostigma; Moraceae) includes 72 species restricted to the African floristic region (a few extending to the Arabian Peninsula and Socotra). We present the first molecular phylogenetic analysis of the section including 56 ingroup (representing 44 species) and three outgroup taxa, to investigate its monophyly, classification and evolution. We used sequence data from the nuclear ribosomal internal and external transcribed spacers (ITS and ETS). Our results suggest that section Galoglychia is paraphyletic to the neotropical section Americana, although this is not supported by bootstrap analysis and only weakly supported by Bayesian posterior probabilities. Maximum parsimony analysis conflict with maximum likelihood and Bayesian analyses with respect to the closest relatives of section Americana in Africa. The subsections of section Galoglychia proposed by Berg (Proc. Kon. Ned. Akad. Wetensch., Ser. C, 89, 121-127, 1986) are generally supported. We find two major clades of section Galoglychia within Africa possibly corresponding to two main centres of diversity. One clade comprises members of subsections Platyphyllae and Chlamydodorae, which are more concentrated in Eastern Africa, and extend to Madagascar and neighbouring archipelagos (Comores, Mascarenes, Aldabra Islands and Seychelles). The other main clade includes members of subsections Caulocarpae, Cyathistipulae, Crassicostae and Galoglychia, which are concentrated in West and Central Africa.} }
