   Notes: Survival was measured across two time periods, October 1995 – March 1997 and during the El Niño of March – October 1997.  Survival 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.  The eight HIGH and six LOW 0.5-ha areas were nested within conspecific adult density.
