Fig. 4: Effects of soil microbial communities on the agroecosystem stability and functions under elevated CO2 and temperature in wheat season.

a A multiple regression model for assessing the relationship between soil microbial communities and ecosystem functions. b The linear relationship between ecosystem stability and soil nematode abundance. c The linear relationship between ecosystem multifunctionality and soil bacterial abundance. d The linear relationship between ecosystem multifunctionality and soil nematode structure. The colors in the figure represent Pearson’s correlation, where blue and red indicate negative and positive connections, respectively.
