Regeneration guilds include non-pioneer, light demanding (NPLD) and shade bearer (SB). Dispersal mode categories include primate (P; arboreal primates, chimpanzees and gorillas), bird (B), elephant (E), and wind (W). Seed sizes are averaged seed lengths measured from 100 seeds of each species. Average conspecific density was estimated from 30, 1-ha vegetation plots in which stems >10 cm dbh of all tree species were measured, mapped, and identified to species. Seed rain densities are the average densities after two years of monitoring (n = 630 traps).
