Data from: Widespread range contraction of carnivores in protected areas of China

The data and R code supporting the findings of this manuscript:
Jiekun He, Ludan Zhang, Jiehua Yu, Fang Wang, Zhishu Xiao, Jiajia Liu. Widespread range contraction of carnivores in protected areas of China.

1. SOFTWARE
All the computational analyses were performed in R 4.3.0. R is an open source software, and can be installed on the most normal desktop computer.

2. CODE SCRIPTS
The file "00RCode.R" is an annotated R script file containing the analyses we ran for our manuscript.

3. INPUT DATA
The file "01mammal_100tree.trees" contains a set of 100 random phylogenetic trees used in the analyses.
The file "01SpeciesLevel.csv" contains species-level data of 56 mammal species used in the analyses. The dataset contains only species with more than five historical records, for which we have complete data on the magnitude of range contraction in protected areas per species.
The file "02SpeciesLevelNew.csv" contains species-level data of all 82 mammal species used in the analyses.
The file "03SiteLevel.csv" contains location-level data used in the analyses.

4. NOTE
For details on data collection, processing and analysis, please see the Methods section of the associated manuscript.
