Normalized signal intensities of representative genes involved in a C decomposition and b methane cycling, as revealed by GeoChip 5.0 analysis. Blue bars represent the average normalized signal intensity of probes of each gene of control samples, and red bars represent warmed samples. Error bars represent standard error of the mean for n = 6 biological replicates. The differences of the functional gene relative abundance between warming and control samples were tested using ANOVA, indicated by * when p < 0.050
