   Notes: Growth (change in height) was measured during two time periods, October 1995 – March 1997 and during the El Niño of March – October 1997.  Growth was tested against adult density and juvenile size (in three classes: 25 cm tall, 26 – 75 cm tall, >75 cm tall) in a repeated-measures nested MANOVA, plots (n = 72) nested within 0.5 ha areas, which were themselves nested within conspecific adult density (HIGH (n = 8) vs. LOW (n = 6)).
