Diversity (a), mean phylogenetic trait distance (MPD) (b) and nearest neighbor phylogenetic distance (NNPD) (c) as a function of evolutionary time and niche widths (σcon). MPD in (b). is scaled using σcon = 0.1 as reference and the y-axis thus shows the change factor of MPD at different σcon values compared to the σcon = 0.1 baseline. Insert in (b). show non-scaled MPD values as a function of evolutionary time and σcon, indicating a low variation among σcon –scenarios and a monotonic increase in MPD with time. All results are shown as means over 20 simulation replicates (see variation across replicates in Fig. S1). Model parameters that were kept constant for the simulations were: K0 = 10,000; σK = 1; r = 1; µ = 0.01; σµ = 0.02. Figure produced in MATLAB version R2019a.
