#Figure 3  This is a PCoA plot with samples from the "Wildlife of Our Homes" Project and Project MERCCURI combined. The closer the spheres are, the more similar the microbial communities are. In this plot, all of the ISS samples are the same color (red), and you can see how they compare to various surfaces on Earth homes.
