Other claims from this paper (5)
- Observation Trees that survived the drought showed strong correlations among and between basal area increment, BAI/BA, pa-pc and climate.
- Association Trees that died during the drought had greater growth sensitivity to climate than trees that survived.
- Observation In trees that died, pa-pc showed no sensitivity to climate.
- Association In trees that died, the relationship between pa-pc and BAI/BA was steep.
- Observation The pa-pc results are consistent with predictions from a theoretical hydraulic model.
