Oliveira_et_al_AmphiBIO_v1

Amphibion represents an unprecedented compilation of natural history traits for amphibians worldwide. We gathered information on 19 traits related to ecology, morphology and reproduction features of amphibians. Our database comprises 6,776 amphibian species of all orders (Anura, Caudata and Gymnophiona), 61 families and 531 genera. The data provided here has 41,270 filled cells along 19 traits of interest. In total, we extracted and aggregated the data from the 1,711 literature sources. We also provide a second data set in which we used an imputation approach to fill cells lacking information. This database has the potential to allow unprecedented large-scale analyses in an array of research areas. Examples of potential uses include estimate rates of phenotypic evolution, testing community assembly hypotheses, identify traits associated with extinction risk, uses in phylogenetic comparative analyses and selection of hotspots for amphibians conservation.

Amphibion 是全球两栖动物自然历史特征的空前系统性汇编。本数据集收集了与两栖动物生态、形态及繁殖特征相关的共19项性状信息，涵盖所有目（无尾目Anura、有尾目Caudata和蚓螈目Gymnophiona）下的6776种两栖动物，涉及61个科与531个属。本次发布的数据中，19项目标性状共包含41270个有效填充数据单元格。总体而言，我们从1711篇文献来源中提取并整合了全部数据集内容。此外，我们还附带发布了第二份数据集，该数据集通过缺失值插补方法对缺失信息的单元格进行了填充。本数据集有望支持诸多研究领域中前所未有的大规模分析工作，其潜在应用场景包括：估算表型演化速率、检验群落组装假说、识别与物种灭绝风险相关的性状、开展系统发育比较分析，以及遴选两栖动物保护热点区域。
