Figure 1. Winter warming increased the relative abundances of
fungal functional genes for C degradation and P utilization. Response
ratios show significant increases of genes encoding xylose reductase,
vanillin dehydrogenase, invertase, and phytase (indicated by ** forP < 0.01 and * for P < 0.05). C
substrates are arranged in the order from labile C to recalcitrant C.
Error bars indicate 95% confidence intervals of differences of
functional gene data between warmed and control samples.
