English abstract In the Amazonian floodplains, trees are subjected to regular periods of flooding which ranges from waterlogging of the rhizosphere to submergence of the whole plant. However, the lack of water during certain periods of the year can strongly affect tree growth as well. Drought is especially critical for seedling establishment, because the driest conditions prevail in the same time as flood waters recede and establishment takes place. In the light of climatic changes, increases in frequency and intensity of dry periods justify an analysis of tree responses to these drastic events. The present review aims at bringing data together which enables us to understand the different responses of primarily flood-resistant trees to drought
Portuguese abstract Na planície amazônica, as árvores estão regularmente sujeitas a períodos de inundação que variam do encharcamento da rizosfera até a submersão da planta toda. Entretanto, a falta de água durante alguns períodos do ano também pode afetar intensamente o crescimento das árvores. A seca é especialmente crítica para o estabelecimento de plântulas, pois as condições mais secas prevalecem quando as águas baixam e o estabelecimento ocorre. Diante as mudanças climáticas, aumentos na frequência e intensidade de períodos secos justificam uma análise das respostas das árvores a estes drásticos eventos. A presente resenha visa reunir os dados que nos permitam entender as diferentes respostas à seca de árvores primariamente resistentes a inundações
