Figure 4
Ordination plots of the redundancy analysis (RDA) to identify the relationship between the abundance of microbial taxa (blue arrows) and LOC (red arrows). (a) The relationship between the soil microbial taxa and soil active organic carbon in Picea asperata Mast.; (b) the relationship between the soil microbial taxa and soil active organic carbon in Betula albosinensis. Sp, Su, Au and Wi represent spring, summer, autumn, and winter, respectively. The abbreviations of the microbial taxa are as follows: Aci: Acidobacteria; Pro: Proteobacteria; Bac: Bacteroidetes; Fir: Firmicutes; Act: Actinobacteria; Lat: Latescibacteria; Chl: Chloroflexi; Eur: Euryarchaeota; Bas: Basidiomycota; and Asc: Ascomycota (this figure is made by Canoco, version 5.0, 2012, Microcomputer Power, Ithaca, NY, USA; software available at: http://www.canoco5.com/).
