Here we sample all of Taiwanese endemic species (i.e., B. aristatoserrulata, B. brevisepala, B. chingshuiensis, B. hayatana, B. kawakamii, B. mingetsensis, B. nantoensis, B. pengii, B. ravenii, B. schaaliae, and B. tarokoensis) and endemic species from Philippines and China, as the out groups. We constructed a well-supported phylogenetic tree based on 32,505 SNPs filtered from RAD-Seq data. The lineage of three group corresponding to geographic and morphological data. Except for the argument between B. kawakmii and B. pengii, the phylogenetic tree confirmed the delimitations of previous species and two new species (B. alpicola and B. morii sp. nov.). With the results of species niche modeling (Last glacial period) and chromosome number (2n=28), we infer to main speciation by geographic isolation. The result also confirms the utility of RAD-Seq data for reconstructing phylogenetic relationships in young and rapid lineages. Kuo-Fang Chung Kai-Yi Chen 鍾國芳 陳凱儀 2017 學位論文 ; thesis 76 zh-TW |
