Figure 2: Nutrient enrichment increases the per cent of dormant taxa and decreases active diversity.

Per cent of dormant taxa (a) in N-enriched (red) and reference (blue) marshes and Shannon diversity of the potentially active community, as assed by 16S rRNA for tall S. alterniflora (TSA; b) and S. patens (SP; c). Boxes represent 25–75% quartiles, and the solid black line is the median value. Nutrient enrichment induced a decrease in active diversity (F=12.49, P<0.01, N=192).
