TABLE H1. Habitat associations of 15 species of Myristicaceae seedling on the Yasuní FDP. Numbers in each habitat show the frequency of occurrence within 5 × 5 m subplots.chisquareand P values are from a randomisation test in which habitats were shuffled among plots (see main text for details). Significance indicated by asterisks *P < 0.05, NS = nonsignificant.
