The correlations between module eigengenes and environmental traits in the warming pMEN. The color of each plot indicates the correlation between corresponding module eigengene and environmental trait. Red color means highly positive correlation and green color means highly negative correlation. The numbers in each plot are the correlation coefficient (r) and significance (p) in parentheses. The environmental traits include soil pH value (pH), NO3-nitrogen content (NO3N), soil carbon content (SC) and average soil temperature (avgT).
