Amazon forests are being degraded by myriad anthropogenic disturbances, altering ecosystem and climate function. We analyzed the effects of a range of land-use and climate-change disturbances on fine-scale canopy structure using a large database of profiling canopy lidar collected from disturbed and mature Amazon forest plots. At most of the disturbed sites, surveys were conducted 10?30 years after disturbance, with many exhibiting signs of recovery. Structural impacts differed in magnitude more than in character among disturbance types, producing a gradient of impacts. Structural changes were highly coordinated in a manner consistent across disturbance types, indicating commonalities in regeneration pathways. At the most severely affected site ? burned igapó (seasonally flooded forest) ? no signs of canopy regeneration were observed, indicating a sustained alteration of microclimates and consequently greater vulnerability to transitioning to a more open-canopy, savanna-like state. Notably, disturbances rarely shifted forests beyond the natural background of structural variation within mature plots, highlighting the similarities between anthropogenic and natural disturbance regimes, and indicating a degree of resilience among Amazon forests. Studying diverse disturbance types within an integrated analytical framework builds capacity to predict the risk of degradation-driven forest transitions. |

This work was developed in order to adapt and to test the employment of the color system CIE in AVIRIS hiperspectrais images with the purpose to distinguish vegetation patterns in different substrata. It was used as test area the Niquelandia, GO image with nickel ore concentration, where the distribution and characteristic of the vegetation presents a strong geologic control. The atmospheric correction was made by the Green method. After that it was made the estimate of the values CIE (x, y, z and Y), being generated the relative images to the red, green, blue colors and brightness, respectively. Among the generated color composition (xyz and xyY), the one that uses the brightness (xyY) it allowed a better differentiation of the vegetation than it happens on the ultramafic rocks. The use of the color concept provides a reduction of the spectral space and it allows a better interactivity with the analyst due to the visual approach. The use of the color concept in the Niquelandia area allowed the differentiation of vegetation patterns in soils originated from ultramafic and mafic rocks. |
