Cluster dispersal shapes microbial diversity during community assembly
Fig 6
Bimodality coefficient and mean relative abundance across multiple cluster sizes reveal patterns of selection.
In all panels, each data point shows the mean relative abundance of species A and the bimodality coefficient obtained from an abundance fluctuation distribution simulated over 104 microbial communities. Illustrative examples of these distributions for different parameter regimes are provided in S2 Fig. Each panel corresponds to a different dispersal rate c. Colors correspond to cluster size, with darker shades indicating higher cluster size. The bar denotes the gradient of cluster sizes from low (light) to high (dark). Parameter values: replication rate of A (red, green, yellow, purple)
(blue), replication rate of B
(red, blue, green, purple)
(yellow), relative abundance of A in the pool
(blue, green, yellow)
(red)
(purple), carrying capacity K = 105, cluster size n = 1−200.
