Phylodiversity accumulation and model fitting in the three datasets. a Empirical and surrogate phylodiversity accumulation curves. Surrogate curves are colored according to the D value. New species with a previously detected close relative contribute little phylodiversity and cause slow phylodiversity accumulation (blue). New species that do not have a close relative contribute more phylodiversity and cause faster accumulation (green). b Empirical and surrogate data are compared to generate an estimate for D. The red arrows show the process of error minimization, yielding a D estimate. c Dispersion parameter (D) estimates. The dot in the center of a violin is the mean, and bars represent 95% confidence intervals for the D estimate. d Testing against alternative “individual null.” The “individual null” is an alternative null model that accounts for the relative abundance of OTUs in the data subset
