Supplement 1. Fully abstracted biological and methodological data (and associated literature citations) used in a cross-system meta-analysis of correlates of the strength of trophic cascades.

File List Supplement1.csv -- data from the 114 studies used in the meta-analysis Description This file contains data from the 114 studies used in the meta-analysis. The first line contains column headings that are defined below. At the bottom of Supplement1.csv are 3 rows for QA/QC. Labels for these rows can be found at the right side of the spreadsheet. In order, from top to bottom, the columns provide: (1) sum of all data in the column, (2) number of non-numeric cells in the column, and (3) number of missing values in the column. At the right side of Supplement1.csv, for each row of the spreadsheet, 3 columns provide: (1)sum of all data in the row, (2) number of non-numeric cells in the row, and (3) number of missing values in the row. In the file Supplement1.csv each line within the predator, herbivore, and plant sections contains information for a species, if named in the original study. If not named, these data were generally lumped into a single category. Thus, a single study can be represented by several lines of data. Most analyses were done, as per the Methods section, on means across categories. Text description, values, and units of factors from Supplement1.csv: -- TABLE: Please see in attached file. --

文件列表 Supplement1.csv —— 本文件包含元分析（meta-analysis）所用的114项研究的数据
描述 本文件包含元分析纳入的114项研究的数据。文件首行为列标题，下文将对其进行定义。Supplement1.csv 文件底部设有3行质量保证与质量控制（Quality Assurance/Quality Control，QA/QC）记录，这些行的标签可在电子表格右侧查看。各列从上到下依次为：(1) 该列所有数据的总和，(2) 该列中非数值单元格的数量，(3) 该列中缺失值的数量。在Supplement1.csv 文件的右侧区域，针对电子表格的每一行，设有3列依次为：(1) 该行所有数据的总和，(2) 该行中非数值单元格的数量，(3) 该行中缺失值的数量。
在Supplement1.csv 文件中，捕食者（predator）、植食者（herbivore）与植物（plant）模块内的每一行，对应原始研究中已命名物种的相关信息；若物种未被命名，则此类数据通常会被归入单一分类类别。因此，单一项研究可对应多条数据行。按照方法部分的描述，大多数分析均基于各分类的均值开展。
