Fig. 5

Patterns of species richness and diversity within HPC forest. (a) depicts species rank/abundance curves (abundance data in log-normal scale) for species observed at all tree sizes as well as in different size categories (in terms of ‘estimated above-ground biomass’ eAGB). (b) depicts species rarefaction curves (for the entire forest, and for R- and B-forest separately) from plot data (large dots, averages of 12 resamplings) as well as overall fitted log-logistic models, adjusted for spatial inter-plot distance to represent species increase with contiguous area (models were based on plot data but plot-to-plot steps were lowered by a factor of 0.56 as determined via comparison to plot-scale species rarefaction models in Additional file 1: Figure S2)
