A Jungle in There: Bacteria in Belly Buttons are Highly Diverse, but Predictable

Figure 1

The frequency of bacteria phylotypes (each point = a phylotype) in our first sample of human belly buttons predicts most of the variation in the frequency of the same phylotypes in our second sample.

The size of circles corresponds to the number of reads of each phylotype, where reads are a proxy for abundance. 1380 points are plotted here, though many fall on top of each other.
