在大洋洲、新几内亚和东瓦拉科（ONGEW）的陆生脊椎动物区系中，皮类动物占主导地位。然而，他们的多样性的知识是不完整的，他们的保护需求知之甚少。Aims To explore the diversity and threat status of the skinks of ONGEW and identify knowledge gap and conservation needs.Methods我们编制了一份清单，所有的石龙子物种发生在该地区和它们的威胁类别指定的国际自然保护联盟。我们使用国家生物技术信息中心基因库中保存的可用基因序列来生成该地区石龙子的遗传学。然后，我们评估其多样性的地理分区内，并比较其他爬行动物类群在region.Key结果约300种石龙子发生在ONGEW，使其成为第二大全球热点的石龙子多样性澳大利亚之后。许多系统发育关系仍然没有解决，许多种和属需要分类修订。五分之一的物种面临灭绝的威胁，比几乎所有的爬行动物家庭在region.Conclusions ONGEW包含了很大比例的全球石龙子多样性的<1%的地球陆地。许多是地方性的，面临着栖息地丧失和入侵捕食者等风险。然而，鲜为人知的是，他们和许多物种需要分类修订和威胁级别reassessment.Implications-的石龙子的ONGEW是一个多样化的，但underexplored组的陆生脊椎动物，许多物种可能面临极端的风险，在不久的将来。需要进一步的研究来了解他们面临的威胁以及如何保护他们。
Context Skinks comprise the dominant component of the terrestrial vertebrate fauna in Oceania, New Guinea, and Eastern Wallacea (ONGEW). However, knowledge of their diversity is incomplete, and their conservation needs are poorly understood.Aims To explore the diversity and threat status of the skinks of ONGEW and identify knowledge gaps and conservation needs.Methods We compiled a list of all skink species occurring in the region and their threat categories designated by the International Union for Conservation of Nature. We used available genetic sequences deposited in the National Center for Biotechnology Information’s GenBank to generate a phylogeny of the region’s skinks. We then assessed their diversity within geographical sub-divisions and compared to other reptile taxa in the region.Key results Approximately 300 species of skinks occur in ONGEW, making it the second largest global hotspot of skink diversity following Australia. Many phylogenetic relationships remain unresolved, and many species and genera are in need of taxonomic revision. One in five species are threatened with extinction, a higher proportion than almost all reptile families in the region.Conclusions ONGEW contain a large proportion of global skink diversity on <1% of the Earth’s landmass. Many are endemic and face risks such as habitat loss and invasive predators. Yet, little is known about them, and many species require taxonomic revision and threat level re-assessment.Implications The skinks of ONGEW are a diverse yet underexplored group of terrestrial vertebrates, with many species likely facing extreme risks in the near future. Further research is needed to understand the threats they face and how to protect them.
