Table 4. Nestedness of Acanthamoeba and Myxomycetes OTUs per region and per site. The sites are in rows and the OTUs in columns. Nestedness (p-value < 0.05) is indicated by numbers in bold.

NODF values are comprized between 0 (no nestedness) and 100 (maximum nestedness), Z values > 1.64 indicate significance at p = 0.05.
BR values increase with nestedness, Z values < 1.64 indicate significance at p = 0.05.
Nestedness among rows = species composition.
Nestedness among columns = species occupancy of sites.
