Figure 2

Fungal ribosomal large subunit gene richness in libraries (OTU = 97% sequence similarity). Data are means with standard deviation of richness in three pyrotag libraries per field treatment for each soil depth interval examined. White bars: aCO2, light gray bars: eCO2, dark gray bars: N-fertilization, black bars: eCO2 + N-fertilization.
