Details of the three best fitting models (Table 1) for the site average shift rate (n = 43). Predictor variables are scaled (cf. the scale() function in R) for comparison purposes
*See Supplementary Tables 1 and 2 for unscaled estimates and weighted coefficients of model 2, the most parsimonious model
T: baseline temperature, Loss: forest loss percentage, Cover: forest cover percentage, Type: taxa type (animal or plant)
