Map of diversity observed from oiled and non-oiled samples. Bacterial diversity was dominated by class gamma proteobacteria and alpha proteobacteria. Inner circle represent the phylogenetic tree and mid rings correspond to heat map of various genera distributed in different samples H1 (enrichment), H2 (oiled sediment), H4 (oiled water), H5 (non-oiled water) and H6 (non-oiled sediment). Bar plot on outside of the circle indicate the species abundance in all samples and height of the bar corresponds to absolute OTU count.
