FracFeed - Global database of the fraction of feeding predators

A compilation of predator diet surveys that report on the proportion of "empty stomachs" or "not feeding individuals" (i.e., the <i>Frac</i>tion of <i>Feed</i>ing individuals).<br><i>FracFeed_Data.csv</i> - the compilation of fraction feeding and covariate data;<i>FracFeed_Metadata.csv</i> - column descriptions for FracFeed_Data;<i>FracFeed_Citations.csv</i> - source citations for FracFeed_Data;<i>FracFeed_Citations_BodyMass.csv</i> - source citations for predator body mass informationTaxonomic standardization uses the Open Tree of Life through the rotl package.For interim updates, see https://github.com/marknovak/FracFeed_DB本数据集为捕食者食性调查成果汇编，收录了"空胃个体"或"未摄食个体"的占比，即摄食个体占比（Fraction of Feeding individuals，以下简称FracFeed）。 FracFeed_Data.csv：收录摄食个体占比与协变量数据的数据集文件； FracFeed_Metadata.csv：FracFeed_Data.csv的列字段说明文档； FracFeed_Citations.csv：FracFeed_Data.csv的来源引用文件； FracFeed_Citations_BodyMass.csv：捕食者体重相关信息的来源引用文件。 分类学标准化流程通过rotl软件包调用生命之树（Open Tree of Life）完成。 如需获取临时更新，请访问 https://github.com/marknovak/FracFeed_DB
