Other claims from this paper (7)
- Observation Stand mean light-saturated photosynthesis was 8.8, 11.3 and 7.2 μmol CO2 m−2 s−1 at 1000, 2000 and 3000 m, without a significant altitudinal trend.
- Observation Stand mean leaf dark respiration was 0.8, 0.6 and 0.7 μmol CO2 m−2 s−1 across the three elevations, with no significant trend.
- Observation Among-species variation in photosynthesis and respiration was 20–53%.
- Association Pantropical area-based photosynthesis decreased by 1.3 μmol CO2 m−2 s−1 per km altitude increase.
- Association Pantropical area-based photosynthesis decreased by 0.2 μmol CO2 m−2 s−1 per K temperature decrease.
- Association Geological and soil fertility conditions and foliar N and P influenced altitude patterns in photosynthesis.
- Mechanism Reduced photosynthesis and stand leaf area decreased canopy carbon gain with elevation.
