Fig. 2From: Tree and shrub richness modifies subtropical tree productivity by regulating the diversity and community composition of soil bacteria and archaeaSoil bacterial and archaeal α-diversity and community structure. a tree richness and shrub richness effects on soil microbial α-diversity; b tree richness and shrub richness effects on soil microbial β-dissimilarity. The asterisks showed the p-value significance level, *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001 and ns showed no significanceBack to article page
