Environmental Data
According to our Principal Component Analysis (PCA) of climate factors,
the first five principal components explain 91.14% of variations (Table
1). PC1 is mainly represented by the increased temperature and reduced
elevation, while PC2 explains increased precipitation, PC3 explains Mean
diurnal range and Precipitation seasonality, both PC4 and PC5 represent
extreme temperature and precipitation. The first three principal
components are presented in Figure 3a, for more details, please see
