Bacterial Diversity Assessment in Antarctic Terrestrial and Aquatic Microbial Mats: A Comparison between Bidirectional Pyrosequencing and Cultivation
Figure 2
Overview of the distribution of the phyla per sample for the reverse sequencing dataset.
Circle area is a log2 transformation of the number of sequences ([log2(N)*5/PI], with N the number of sequences in that phylum). Color intensity is an approximation for the number of OTUs per sequence (total OTUs/total sequences). The first two columns show the total number of sequences and diversity of each phylum for pyrosequencing and cultivation separately. The order of the phyla is as in Figure 1 and additional phyla were added at the bottom. The yellow to red scale shows pyrosequencing data, the blue-purple scale the cultivation data.
