The stochastic logistic model with correlated carrying capacities reproduces beta-diversity metrics of microbial communities
Fig 3
Comparison between the relationships between dissimilarity measures in empirical data and according to the model.
The different dissimilarity measures (A: Jaccard similarity, B: Sørensen index, C: Whittaker index D: Bray-Curtis disimilarity, E: Horn similarty, F: Morisita-Horn similarity) are plotted against the carrying capacity correlation ρK. Black circles correspond to pairs of empirical samples from the same host, while grey squares correspond to pairs of empirical samples from different hosts (but of the same dataset). The value of ρK for individual samples is inferred as specified in the Methods. Red dots are the binned average of the predictions of the model. The model is simulated with the distributions of K and σ fitted from the data, and with a number of species equal to the one estimated (see Section B in S1 Text). The number of reads is equal to the average number of reads for the empirical samples, 3 ⋅ 104.
