Heatmap of Centered Log Ratio (CLR) transformation of taxa relative abundance at family level.

<p>The figure shows the 15 most abundant families. Higher CLR values are colored red and correspond to higher relative abundances, while lower CLR values are colored blue and correspond to lower relative abundances. In the legend above the graph blue corresponds to WNV-positive samples and light blue to WNV-negative samples. The tree below the graph shows the samples grouped according to the similarity of microbiota composition based on Euclidean distances.</p> <p>(PDF)</p>
