G.  aCommunity composition of tree and palm species following disturbance in a forest with bamboo in southwestern Amazonia, Brazil.h[electronic resource]  c2021  aAnthropogenic disturbances such as selective logging and forest fires can cause further degradation in tropical forests. Various authors have suggested that logging and fire in southwestern Amazonia can increase bamboo abundance and contribute to slowing succession, but few studies have addressed community-composition patterns at either the local or the regional scale. We used a natural experiment with forest fire and post-burn logging to analyze the effects of increased bamboo abundance on the community composition of trees and palms in Brazil's Acre state in southwestern Amazonia. Bamboo abundance was expressed by variables collected both by field sampling and from high-resolution images using a remotely piloted aircraft (RPA). Disturbance in these forests was associated with a significant reduction in the number of crowns of emergent trees and palms and an increase in the canopy fraction occupied by bamboo. A significant negative relationship was observed between the canopy area occupied by bamboo and the number of tree and palm species, regardless of the level of disturbance. Bamboo density (culms m-2) and canopy area occupied by bamboo had significant effects on community composition, indicating that bamboo abundance is a key driver affecting the floristic composition of the forest.  aAnthropogenic activities  aBamboos  aBotanical composition  aDegradation  aTropical forests  aBambu  aComposição Botânica  aDegradação Ambiental  aFloresta Tropical  aAC-090  aAcre  aActividades antropogénicas  aAl suroeste de la amazonia  aBambúes  aBosques tropicales  aComposición botánica  aDegradación  aDominant species  aEspecies dominantes  aRio Branco (AC)  aRodovia Transacreana  aSouthwestern Amazonia  aSudoeste da Amazônia  aTransacreana Highway1 aGRAÇA, P.
