Fig. 3From: Representative sampling of natural biofilms: influence of substratum type on the bacterial and fungal communities structureVariability of the fungal community structure within substrata types for biofilms collected in November 2009 from replicates of different natural substrates: a Negative image of the DGGE gel, b Dendrogram of Jaccard distances calculated from the DGGE band presence/absence matrix and c Principal component analysis of band intensity profiles of gene fragments coding for 28S rRNA (only the first two factors/components have been represented)Back to article page
