Fig 3. Successional, spatial, and seasonal changes in the diversity of seeds dispersed abiotically and biotically in tropical secondary forests of southern Bahia, Brazil.

Species diversity was estimated as species richness (a, c, e; Hill number 0 or ⁰D) and Simpson diversity (b, d, f; Hill number 2 or ²D) using sample-coverage based rarefaction and extrapolation. Sample coverage was 97.9% for a and b, 98% for c and d, and 96% for e and f. Whisker bars are 95% confidence intervals.
