Extended Data Fig. 3: Randomization analysis of the M19 model.
From: A simple dynamic model explains the diversity of island birds worldwide
Distribution of global hyperparameters estimated from each of 1,000 datasets with the same phylogenetic data as our main global dataset but randomly reshuffling archipelago area and isolation among the 41 archipelagos in the dataset. Grey histograms show DAISIE maximum-likelihood parameter estimates for the M19 model. Red arrows show the estimated parameter from the real data. In most cases, the hyperparameters describing the exponent of the power models (x, α, β and d0) are estimated as zero in the reshuffled datasets, which is not the case in the real data (red). Parameters are explained in Supplementary Table 1.
