Data from: Archipelago-wide survey of Philippine forest dragons (Agamidae: Gonocephalus): multilocus phylogeny uncovers unprecedented levels of genetic diversity in a biodiversity hotspot

We utilize robust geographical genetic sampling, a multilocus dataset, and coalescent-based species delimitation statistics to provide the first phylogenetic inferences of relationships of Philippine Gonocephalus, combined with estimates of putative species diversity in this virtually unknown island radiation. Our results reveal startling levels of undocumented diversity, genetically partitioned at a number of geographic levels across the archipelago. In this paper we present the first survey of genetic lineage diversity, coupled with an archipelago-wide elucidation of geographic structure in a unique archipelago-endemic radiation. Philippine Gonocephalus have previously escaped the attention of biogeographers, due to taxonomic confusion associated with low numbers of preserved specimens in museum collections. With new vouchered material and genetic sampling from a comprehensive, archipelago-wide vertebrate biodiversity inventory, our findings join many recent studies highlighting the unprecedented faunal diversity in one of the world’s most unique biodiversity conservation hotspots.本研究采用可靠的地理遗传采样方案、多基因座（multilocus）数据集以及基于溯祖理论（coalescent theory）的物种界定统计方法，首次对菲律宾棘龙属（Gonocephalus）类群的亲缘关系开展系统发育推断，并对这一几乎未被认知的岛屿辐射演化类群的推定物种多样性进行了评估。研究结果揭示了数量惊人的未记录物种多样性，这些多样性在整个群岛的多个地理层级上均存在遗传分化。本文首次针对该类群开展遗传谱系多样性调查，并对这一独特的群岛特有辐射演化类群的全群岛地理结构进行了系统阐明。此前由于博物馆馆藏标本数量稀少引发的分类学混乱，菲律宾棘龙属类群长期未受到生物地理学家的关注。依托全新的凭证标本与全群岛范围脊椎动物生物多样性综合调查获取的遗传采样数据，本研究结果与近期多项研究一道，彰显了全球最具独特性的生物多样性保护热点地区之一所蕴藏的前所未有的动物区系多样性。
