Posterior (marginal) densities for estimated parameters (P1, Model 1).

Each subplot shows the histogram of the samples from the approximate parameter posterior. The x-axis represents the values of the estimated parameters and the y-axis represents the frequencies. The subplots on the first column show the distribution of the growth rates μs and the rest of the subplots show distributions of the interaction parameters αss′. Recipient and donor species are listed in rows and columns, respectively. The x-axis is scaled to show μ ± 3σ where the μ is the mean and the σ is the standard deviation of the posterior distribution.
