Fig. 3From: Long-term nitrogen deposition enhances microbial capacities in soil carbon stabilization but reduces network complexityChanges in N cycling gene abundances. The percent change in brackets for each gene is calculated as 100*(( mean value in N deposited samples/mean value in control samples) – 1). Orange and blue represent increases and decreases in gene relative abundance in response to N deposition, respectively. Gray-colored genes are not targeted by GeoChip. Asterisks indicate significant differences. *P < 0.050; **P < 0.010Back to article page
