Figure 4: Relationships among bacterial communities from different host species and habitats.

From: Marine mammals harbor unique microbiotas shaped by and yet distinct from the sea

Figure 4

Only samples with ⩾372 reads were included (n=199; one specimen per body site per animal). (a) NMDS Bray–Curtis ordination of PS-analysed specimens from dolphins and sea lions included in this study. Colours indicate the different specimen types and sources. Shapes display the location of the animal during sampling (San Diego or an undisclosed alternate, distant location for the MMP animals and Sarasota Bay for the wild, free-living dolphins). (b) Distance Threshold Network analysis of marine mammal-associated bacterial communities. The network displays binary relationships between specimens and OTUs using a Bray–Curtis distance and a Fruchterman–Reingold layout. Each data point represents the bacterial community from an individual specimen. Two specimens are considered ‘connected’ if the distance between them is less than a user-defined threshold, here, 0.6. The thickness of the connecting edge is related to the distance between two specimens. OTU abundances were proportionally transformed.
