Heatmap of <i>Phyla</i> assignments. Loredana Canfora Giovanni Bacci Flavia Pinzari Giuseppe Lo Papa Carmelo Dazzi Anna Benedetti 10.1371/journal.pone.0106662.g004 https://plos.figshare.com/articles/figure/_Heatmap_of_Phyla_assignments_/1161747 <p>The heatmap reports the normalized values of the taxonomic assignments at <i>phylum</i> level. Each value has been normalized following this criterion: Where <i>X<sub>ij</sub></i> is the occurrence of the phyla ā€˜jā€™ in the site ā€˜iā€™ and N is the number of site in the dataset (in this case 9). Using this transformation each <i>phyla</i> assignment can be compared in all sites independently from its order of magnitude.</p> 2014-09-04 03:47:10 salinity gradient pyrosequencing analysis SRA database saline soil community structure soil characteristics soil salinity PRJNA chemical heterogeneity Bacterial Community diversity salt concentration 16 S rRNA patchy saline soil id Bacterial Diversity
