***P < 0.001, representing the congruence of species turnover between two taxa, partitioned into three fractions by variation partitioning, the congruence between two taxa explained by geographic distance (CTG+CTGE), independently by environmental distance (CTE), and PT represents the congruence between two taxa believed to relate to their direct biotic interaction).
