Appendix A. Life history characteristics and population parameters of 16 species of Myristicaceae in the 25-ha Yasuní forest dynamics plot (FDP).
TABLE A1. Life history characteristics and population parameters of 16 species of Myristicaceae in the 25-ha Yasuní FDP. Mean diameter at breast height (1.3 m, dbh) is based on all stems >1 cm dbh. Mean seed dry mass does not include the mass of the capsule or aril. Ratio of juveniles:adults is calculated from number of stems less than the minimum reproductive size of females:number of stems greater than the minimum reproductive size of females (Queenborough et al. 2007). NA indicates no data available.
