Fig. 4: Changes in microbial diversity and structure in response to switchgrass planting.

a Number of observed species through time. b Phylogenetic diversity. c Detrended correspondence analysis of the 16 S community separated by site for all time points and plots (n = 1428). Significant differences were found between sites, plant cover types, and through time (PERMANOVA, p < 0.01). Dark colors represent the switchgrass samples.
