Other claims from this paper (9)
- Intervention effect Growth rate and biomass partition were similar among light treatments in both Nothofagus species.
- Intervention effect Full sun caused high apical meristem damage.
- Observation Both species produced neoformed leaves during the growing season.
- Observation Neoformed leaves had better photosynthetic capacity than preformed leaves under full sun.
- Intervention effect Morphological traits showed almost no plasticity in response to shade.
- Observation The species differed in optimum photosynthesis temperature.
- Observation N. obliqua maintained high photosynthesis across a wider temperature range.
- Observation Both species had highest net photosynthesis at temperatures higher than their range mean annual temperature.
- Mechanism The authors infer that future warming without water stress could increase carbon fixation, with a small N. obliqua advantage under high temperature variance.
