Cluster dispersal shapes microbial diversity during community assembly
Fig 5
Bimodality coefficient and mean relative abundance across multiple dispersal rates reveal patterns of selection and cluster dispersal.
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 cluster size n. Colors correspond to dispersal rate, with darker shades indicating higher dispersal. The bar denotes the gradient of dispersal rates 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, dispersal rate
