   Notes: The effects of juvenile size (in three classes: 25 cm tall, 26–75 cm tall, > 75 cm tall 1 cm dbh) were tested with a nested ANOVA against ln-transformed (juvenile density m2 + 1), with plots (n = 72) nested within their respective 0.5-ha areas, and areas (n = 16) within adult density (HIGH vs. LOW).
