Leaf dark respiration throughout the vertical profile of a rainforest at Caxiuana, in eastern Amazonia, following 4 years of artificial soil drought. Values represent the mean leaf dark respiration in μmol m−2 s−1±s.d. (n), at 25°C, and compare vegetation subjected to artificial soil drought and normal rainfall (Metcalfe et al. in preparation).
| leaf height | control | drought |
|---|---|---|
| greater than 20 m | 0.52±0.13 (14) | 0.70 (1) |
| 10–20 m | 0.46±0.10 (14) | 0.67±0.25 (12) |
| 0–10 m | 0.30±0.03 (5) | 0.49±0.08 (15) |
| mean | 0.46±0.15 (33) | 0.57±0.19 (28) |
