e0“For seedlings with less than 10% leaf damage, mortality during a 6-mo period spanning the driest part of the drought was three times higher than mortality in the previous and subsequent 6-mo periods (∼10% vs. ∼30%).”

Other claims from this paper (11)
- Association Leaf production was higher during the driest period.
- Association Seedling survival was positively related to leaf number.
- Association Seedling survival was negatively related to leaf damage.
- Observation Dryobalanops lanceolata was the tallest and leafiest species.
- Observation Dryobalanops lanceolata had low levels of leaf damage.
- Association Leaves with more than 50% damage were two to three times more likely to abscise than leaves with less than 10% damage.
- Association Mortality was around twice as high among seedlings defoliated by more than 50% as among those defoliated by less than 10%.
- Observation Fewer than 10% of seedlings were defoliated by more than 50% at any time.
- Association Drought did not seem to alter the effect of defoliation.
- Observation Defoliation levels increased after the drought.
- Mechanism The authors suggested drought may become a more important influence on regeneration as El Niño events become more frequent.
