Fig. 5: Contributions of environmental variables to ecosystem productivity.
From: Metallic micronutrients are associated with the structure and function of the soil microbiome
a Effects of environmental variables (i.e. climate, geo-spatial variance, soil basic properties, soil macronutrients, and soil micronutrients) on ecosystem production via altering bacterial community. b Effects of environmental variables on ecosystem production via altering fungal community. c Effects of environmental variables on ecosystem production via microbial functions. Bacterial community and fungal community include the abundance, diversity, and network connectivity parameters. Microbial function includes the abundance of microbial genes involved in C, N, P, and S cycling. The red and blue arrows represented the significant (p < 0.05) negative and positive relationships between variables respectively, while the arrows with non-significant relationships were not shown. Adjacent values near the arrows indicate the path coefficients. r2 value indicates the proportion of ecosystem production explained by each variable.
