Generalizing clusters of similar species as a signature of coexistence under competition
Fig 4
Impact of immigration and regional diversity.
Clustering increases with regional diversity (black), and has a modal relationship with immigration pressure (red). Bottom axis: number of species in the pool divided by the number of clusters in the community. Top axis: immigration rate. Points show the mean z-score of the Ripley’s K metric across 10 replicates. Error bars show 1.96 standard errors of the mean. (m = 0.08 when varying regional diversity, and the latter is fixed at c. 400 regional species when varying immigration).
