Whole-model tests: Occurrence: (χ² = 14.888, n = 125, P = 0.002); Prevalence: (F = 8.700, n = 31, r²_OLS = 0.581, Predictor+Space r² = 0.632, P < 0.001); Infection intensity: (F = 10.491, n = 31, r²_OLS = 0.458, Predictor+Space r² = 0.582, P < 0.001). Significant variables in the model are highlighted in bold. VIF stands for variance inflation factor and denotes colinearity in the model if higher than 10. Std. coeff stands for standard coefficient. Final models chosen based on Akaike Information Criterion.

*PC1 consolidating latitude and maximum temperature of the warmest month accounted for 96.00% of the variation in the original variables.
