Appendix A. Comparison of climatic predictors among 18 study sites and the 69 sites historically occupied by pika from which they were selected via random sampling stratified by latitude, longitude, and elevation.

Comparison of climatic predictors among 18 study sites and the 69 sites historically occupied by pika from which they were selected via random sampling stratified by latitude, longitude, and elevation.

本研究对18个研究样地与69个历史上有鼠兔（pika）栖息的样地间的气候预测因子进行了比较；其中18个研究样地是通过按纬度、经度与海拔分层的随机抽样，从上述69个历史鼠兔栖息样地中选取得到的。
