Microbial functions and soil nitrogen mineralisation processes in the soil of a cool temperate forest in northern Japan

There is little knowledge about microbial functional community structures and the relationships between communities nitrogen transformation processes. Here, we investigated soil mineralisation potentials in a cool temperate forest throughout growing season. Microbial were assessed by quantification of total bacterial, archaeal, fungal gene abundances bacterial archaeal amoA abundances, predictions bacteria fungi, analysis bacterial-fungal co-occurrence network. In mid-summer, ectomycorrhizal abundance was significantly higher, whereas lower. Bacterial also higher mid-summer. However, regardless seasonal fluctuation net nitrification potential did not show clear seasonality. network analysis, divided into 13 modules, which subgroups assumed to have similar niches. Furthermore, two modules that mainly consisted species Proteobacteria Bacteroidetes positively correlated with potentials. Our results indicated sharing niches, instead could be important factors affecting potential.
