  1. We list the t value and the p value (in parentheses) of a biodiversity variable in a generalized least squares regression that includes the biodiversity variable and all the six climatic and four landscape variables (n is the number of grid cells used in the analysis at low, medium, or high resolution). Two additional parameters are the intercept and the coefficient for land coverage. We also conduct likelihood ratio (LR) test to test if adding the biodiversity variable significantly increases model fit. Significant results are in bold. LR value is shown in italic, after t value (p value)
