NMDS ordination of microbial communities based on ARISA fingerprinting profiles from (a) bacterial and (b) fungal communities, and sequencing-based community composition of (c) prokaryotes and (d) eukaryotes. NMDS ordination was based on Jaccard distances for ARISA data, and Bray-Curtis dissimilarities for sequencing data. OTUs assigned to the following phyla were excluded from the 18S rRNA sequencing dataset prior to ordination: Holozoa, Metazoa, Chloroplastida and ‘NA’. Note that (b) shows the first and third axes as the strongest habitat effect occurred along the third axis while other plots display the first and second axes.
