Results of spatial Simultaneous Autoregressive Models (SAR) are reported (for GLM results compare Supplementary Table S2). Species richness (response) and all continuous predictor variables (except for distance) were log10 transformed.
Significance: *** P <0.001; ** P <0.01; * P <0.05. n.s., not significant.
