Figure 5. Direct gradient analysis of lung explant OTUs at phylotype resolution constrained by subject.

The bacterial communities of human lung explants were binned at a phylotype resolution and constrained ordinations were constructed using the explant from which the sample originated as the constraint. Ordinations were CAP (constrained analysis of principle coordinates) based on (A) Bray-Curtis distance, or (B) Jaccard distance; (C) RDA (the constrained form of PCA); (D) or CCA (the constrained form of CA). Individual samples were colored based on the explant from which they were obtained.
