Diversification history of clown tree frogs in Neotropical rainforests (Anura, Hylidae, Dendropsophus leucophyllatus group)

General consensus emphasizes that no single biological process can explain the patterns of species’ distributions and diversification in the Neotropics. Instead, the interplay of several processes across space and time must be taken into account. Here we investigated the phylogenetic relationships and biogeographic history of tree frogs in the Dendropsophus leucophyllatus species group (Amphibia: Hylidae), which is distributed across Amazonia and the Atlantic rainforests. Using Next Generation Sequencing (NGS) and double digest restriction-site associated DNA (ddRADseq), we inferred phylogenetic relationships, species limits, and temporal and geographic patterns of diversification relative to the history of these biomes. Our results indicate that the D. leucophyllatus species group includes at least 14 independent lineages, which are currently arranged into ten described species. Therefore, a significant portion of species in the group are still unnamed. Different processes were associa...学界普遍共识认为，单一生物学过程无法解释新热带界（Neotropics）内物种分布与分化的格局。反之，必须综合考量时空尺度下多种过程的交互作用。本研究针对分布于亚马孙平原与大西洋雨林的白叶雨蛙物种组（Dendropsophus leucophyllatus，两栖纲：雨蛙科）的系统发育关系与生物地理历史展开探究。本研究利用下一代测序技术（Next Generation Sequencing, NGS）与双酶切限制性位点关联测序（double digest restriction-site associated DNA, ddRADseq），解析了该类群的系统发育关系、物种界定标准，以及对应这两类生物群系历史的分化时空格局。研究结果显示，白叶雨蛙物种组至少包含14个独立演化支系，而目前仅被划分为10个已正式描述的物种，因此该类群中尚有相当比例的物种尚未被命名。不同生物学过程被用于探究……
