Downtown Diet: a global meta-analysis of urbanization on consumption patterns of vertebrate predators

This dataset contains the summary of published studies included in the meta-analysis along with the R code to calculate within-study variation for those studies where this value was not reported. The .csv files with the calculated effect sizes for species richeness, evenness, carbon, and nitrogen stable isotopes are also included., ,本数据集涵盖纳入元分析（meta-analysis）的已发表研究的综述内容，同时附带用于计算未报告研究内变异（within-study variation）值的相关研究的对应R代码。此外还提供了包含物种丰富度、均匀度、碳稳定同位素及氮稳定同位素计算后效应量的.csv格式文件。
