Figures show coefficients ±1 standard error obtained from spatially-explicit models (for pollinator abundance, Sobs and Hurlbert's PIE indices) and partial mantels (method = spearman), controlling for geographic distance (for Bray-Curtis and Morisita-Horn dissimilitude indices). P-values obtained with 1000 permutations: ms = marginally significant,
*p<0.05,
**p<0.01,
***p<0.001.
