Attributes such as diet, foraging strata, foraging time, and body size, in particular, determine a large portion of the “Eltonian” niches of species. Here we present a global species-level compilation of these key attributes for all 9993 and 5400 extant bird and mammal species derived from key literature sources. Global handbooks and monographs allowed the consistent sourcing of attributes for most species. For diet and foraging stratum we followed a defined protocol to translate the verbal descriptions into standardized, semiquantitative information about relative importance of different categories. Together with body size (continuous) and activity time (categorical) this enables a much finer distinction of species’ foraging ecology than typical categorical guild assignments allow. Attributes lacking information for specific species were flagged, and interpolated values based on taxonomy were provided instead. The presented data set is limited by, among others, these select cases missing observed data, by errors and uncertainty in the expert assessment as presented in the literature, and by the lack of intraspecific information. However, the standardized and transparent nature and complete global coverage of the data set should support an array of potential studies in biogeography, community ecology, macroevolution, global change biology, and conservation. Potential uses include comparative work involving these traits as focal or secondary variables, ecological research on the trait or trophic structure of communities, or conservation science concerned with the loss of function among species or in ecosystems in a changing world. We hope that this publication will spur the sharing, collaborative curation, and extension of data to the benefit of a more integrative, rigorous, and global biodiversity science. <i>Key words</i>: <i>bird; body size; diet; eco-informatics; foraging; function; mammal; mass; niche; stratum; traits; vertebrate.</i>文件列表：BirdFuncDat.txt（MD5: d6197b2cd90ca3ece0a7393abbf8b7fc）、MamFuncDat.txt（MD5: 59c3eee29d3ed0a33a002975a5a8cc75）、BirdFuncDatSources.txt（MD5: e4793ab8baa813bba7d168a3d2d6b6a7）、MamFuncDatSources.txt（MD5: 0c67fa8bf6b6ccb7a38fc5229f84508b） 物种的生理、行为与生态特征均受多样的演化与生态约束调控，并共同决定其在生态系统中的角色与功能。其中，食性、觅食层位、觅食时间与体型等特征，可在很大程度上界定物种的埃尔顿生态位（Eltonian niche）。本研究构建了全球物种级别的关键特征汇编数据集，涵盖现存的9993种鸟类与5400种哺乳动物，所有数据均源自权威文献来源。针对多数物种，我们通过全球手册与专著实现了特征数据的标准化采集。针对食性与觅食层位，我们遵循既定流程将文本描述转化为标准化的半定量信息，用以表征不同类别的相对重要性。结合连续型变量体型与分类变量活动时间，本数据集可实现比典型分类类群划分更为精细的物种觅食生态区分。对于缺失特征信息的物种，我们进行了标注，并提供基于分类学的插值估算值。本数据集存在一定局限，包括部分物种缺乏实测数据、文献中专家评估存在误差与不确定性，以及缺乏种内信息等。尽管如此，本数据集具备标准化与透明化的特性，且实现了全球范围的物种覆盖，可为生物地理学、群落生态学、宏观演化、全球变化生物学与保护生物学等领域的诸多研究提供支撑。其潜在用途包括：以这些特征为核心或辅助变量的比较研究、针对群落特征或营养结构的生态学研究，以及关注全球变化背景下物种或生态系统功能丧失的保护科学研究。我们期望本出版物能够推动数据的共享、协作整理与拓展，助力形成更具整合性、严谨性的全球生物多样性科学研究。 关键词：鸟类；体型；食性；生态信息学（eco-informatics）；觅食；功能；哺乳动物；体重；生态位；层位；特征；脊椎动物。
