Changes in plant diet as indicated by shifts in the relative abundance of trnL chloroplast gene sequences.
Plant species were grouped by growth habit (forb, graminoid, and woody). The effect of time in each dataset was tested using repeated measures ANOVA with Bonferroni correction. All three functional groups exhibited significant temporal change in proportion of the diet (P < 0.05).

Plant relative abundance as indicated by sequencing of trnL chloroplast genes.
Plants were identified to species by matching database sequences at the 100% level. See Results for the identity of species in clusters. The effect of time in each dataset was tested using repeated measures ANOVA with Bonferroni correction. Three taxa (Lespedeza violacea, Ceanothus herbaceus, and the Oligoneuron forb cluster) exhibited significant temporal change in proportion of the diet (P < 0.01).
Fig 3.
Relative abundance of microbial phyla as indicated by sequencing of 16S ribosomal RNA genes.
The effect of time on each microbial phylum was tested using repeated measures ANOVA with Bonferroni correction. The phylum Tenericutes exhibited a significant shift in relative abundance over the growing season (P < 0.001).
