Molecular phylogeny and biogeography of Adelanthaceae (Jungermanniales)

世界性的Adelanthaceae（包括Jamesoniellaceae）是Jungermanniales的一个大分支，包括大约100个物种。从低地到páramo安第斯山脉的高海拔地区，阿德兰科植物栖息在广泛的栖息地。迄今为止，阿德莱德科的一般概念主要基于形态学。初步的分子系统发育分析表明，这些概念可能具有多系性。基于分子数据（cp trnLtrnF- Region, atpB-rbcL-spacer, rbcL, nrITS1-5.8S-ITS2），我们将分析adelanaceae及其相关分支的细分，并产生单系属划分。这些新数据还将有助于评估阿德莱德科的物种概念，并根据化石记录、现今分布和分子序列变化来探索阿德莱德科及其相关分支的历史生物地理学。

The cosmopolitan Adelanthaceae (incl. Jamesoniellaceae) is a large clade of Jungermanniales that includes some 100 species. Adelanthaceae inhabit a wide range of habitats from the lowlands up into the páramo region of the high Andes. To date, generic concepts of Adelanthaceae are largely based on morphology. Preliminary molecular-phylogenetic analyses indicate that these concepts may be polyphyletic. Based on molecular data (cp trnLtrnF- Region, atpB-rbcL-spacer, rbcL, nrITS1-5.8S-ITS2) we will analyse subdivisions of Adelanthaceae and related clades, and generate monophyletic genus circumscriptions. The new data will also allow to evaluate species concepts in Adelanthaceae and to explore the historical biogeography of Adelanthaceae and related clades based on the fossil record, present-day distributions and molecular sequence variation.
