Trait-based approaches are becoming extremely common in ecological modeling and the availability of traits databases is increasing. However, data availability is often biased towards particular regions and taxa, with many taxa (e.g., bats) often under-represented. Here, we present the AfroBaT dataset, a compilation of trait data on 320 African bat species containing 76,914 values for 86 traits focusing on morphology, reproduction, life-history, trophic ecology, and species distributions. All data were gathered from published literature following the ecological trait-data standard procedure. Missing data for both numerical and categorical traits were imputed with a machine learning approach including species phylogeny. Trophic ecology traits showed the highest coverage in the literature (72% of the species averaged over all traits), while reproductive traits the lowest. Our data imputation improved the coverage of AfroBaT especially for reproductive traits, going from 27% to 58% of the species covered. AfroBaT has a range of potential applications in macroecology and community ecology, and the availability of open-access data on African bats will enable collaboration and data-sharing among researchers.
基于特征的方法在生态建模中变得越来越普遍,特征数据库的可用性也在增加。然而,数据的可用性往往偏向于特定的地区和分类群,许多分类群(如蝙蝠)往往代表性不足。在这里,我们展示了 AfroBaT 数据集,这是一个关于 320 种非洲蝙蝠物种的特征数据的汇编,其中包含 86 个特征的 76914 个值,这些特征集中在形态、繁殖、生活史、营养生态和物种分布上。所有数据都是按照生态特征数据标准程序从已发表的文献中收集的。对于数值和分类特征的缺失值,我们使用包括物种系统发育在内的机器学习方法进行了估算。营养生态特征在文献中的覆盖率最高(所有特征平均覆盖了 72%的物种),而繁殖特征的覆盖率最低。我们的数据估算提高了 AfroBaT 的覆盖率,特别是对繁殖特征的覆盖率,从 27%提高到了 58%的物种覆盖。 AfroBaT 在宏观生态学和群落生态学中有广泛的应用潜力,非洲蝙蝠的开放获取数据的可用性将使研究人员能够进行合作和数据共享。
