From: Protist communities are more sensitive to nitrogen fertilization than other microorganisms in diverse agricultural soils

Fig. 1

Alpha and beta diversity of the soil bacterial (A, D), fungal (B, E), and protist (C, F) community. Faith_pd index was calculated based on phylogenetic distance at OTU level and displayed in boxplot. The difference in alpha diversity among nitrogen fertilization treatments within a soil type in a season was tested by one-way ANOVA (P < 0.05), and only significant differences observed in a comparison group was labeled with letter. Lowercase letter and capital letter represent the groups in summer and autumn, respectively, and the digit behind the letter means different comparison groups. The asterisk labeled implies the significant difference (P < 0.05) of alpha diversity observed in the treatment between summer and autumn. Beta diversity was analyzed by nonmetric multidimensional scaling (NMDS) based on unweighted unifrac phylogenetic distance metrics at OTU level and displayed in scatter diagram
