             abstract = "Forests in the south-west flank of the Amazon are known by 
                         persistent dominance of Bamboos. It is still not well understood 
                         how species of Bamboos interact with fire, but there is a strong 
                         suggestion that fire favours the spread and colonization of 
                         Bamboos species. On this work we aimed to compare burned and 
                         unburned forested areas dominated by Bamboo through an analysis of 
                         forest structure, spectral attributes and landscape pattern. Two 
                         areas, burned in 2010 and unburned, were sampled with 0.25ha 
                         inventory plots. Three plots were installed in each area, control 
                         (PC) and burned (PQ). We obtained the NIR band, EVI and NDVI 
                         indexes from a RapidEye image of 2012. The spectral attributes 
                         were statistically different between PQ and PC, with higher values 
                         for PC. The higher tree mortality in PQ area suggests lower amount 
                         of NIR reflection, possibly associated to the higher occurrence of 
                         tree crowns with no leaves. The Guido ToolBox software was used to 
                         estimate the proportions of Bamboo, Forest and bare tree crowns in 
                         each area, burned (Q) and non-burned (NQ). The proportion of bare 
                         crowns mixed with forest was found to be more frequent on Q, as 
                         the forest seems to be more heterogeneous. The NQ areas had 
                         greater proportion of non-mixed forest and Bamboo mixed with 
                         forest. The Contagion fragmentarion metric showed lower values of 
                         fragmentation on NQ and higher values on Q. The results indicate 
                         that fire may have favoured the expansion of Bamboo in Q area 
                         leading to the higher fragmentation observed.",
