Tropical forest structural variation across heterogeneous landscapes may control above-ground carbon dynamics. We tested the hypothesis that canopy structure (leaf area and light availability) ? remotely estimated from LiDAR ? control variation in above-ground coarse wood production (biomass growth). Using a statistical model, these factors predicted biomass growth across tree size classes in forest near Manaus, Brazil. The same statistical model, with no parameterisation change but driven by different observed canopy structure, predicted the higher productivity of a site 500 km east. Gap fraction and a metric of vegetation vertical extent and evenness also predicted biomass gains and losses for one-hectare plots. Despite significant site differences in canopy structure and carbon dynamics, the relation between biomass growth and light fell on a unifying curve. This supported our hypothesis, suggesting that knowledge of canopy structure can explain variation in biomass growth over tropical landscapes and improve understanding of ecosystem function. |

Brazilian forests critical are for climate, water, biodiversity, and ecosystem services. The Atlantic Forest and the Amazon are among the most important tropical forests of the world but have different conservation status. The first is below its minimum threshold for biodiversity conservation while the Amazon is approaching its dieback threshold. Aiming to examine policy lessons from the Atlantic Forest which could be applied to the conservation of the Amazon, we first analysed the forest cover of basins of the Amazon compared to the reality of the Atlantic Forest. We found that regions of the Amazon already have forest cover similar to the Atlantic Forest and that 34% of them are below the dieback threshold. We propose policy lessons to avoid that the Amazon follow the same route of the Atlantic Forest and concluded that they need to be implemented urgently in a precautionary approach. |
