The Amazon River basin harbors some of the world's largest wetland complexes, which are of major importance for biodiversity, the water cycle and climate, and human activities. Accurate estimates of inundation extent and its variations across spatial and temporal scales are therefore fundamental to understand and manage the basin's resources. More...

Studying the patterns of dominance and species composition of legumes can contribute to more precise models for nutrient cycling, especially the N-cycle. Leguminosae is the most important family in Central Amazonian floodplain forests surrounding large rivers. The floodplains are classified as nutrient-poor (igapó) and nutrient-rich (várzea) ecosys...

Secondary forests (SFs) growing on previously cleared land could be a low-cost climate change mitigation strategy due to their potential to sequester CO2. However, given widespread changes in climate and land-use in the Amazon in the past 20 years, it is not clear whether current rates of carbon uptake by SFs reflect estimates based on dividing the...

The Amazon basin is being increasingly affected by anthropogenic fires, however, most studies focus on the impact of fires on terrestrial upland forests and do not consider the vast, annually inundated floodplains along the large rivers. Among these, the nutrient-poor, blackwater floodplain forests (igapós) have been shown to be particularly suscep...

Abstract The flood pulse of large Amazonian Rivers is characterized by predictable high- and low-water periods during the annual cycle, and is the main driving force in the floodplains regulating decomposition, nutrient cycles, productivity, life cycles and growth rhythms of floodplains' biota. Over at least 20 millions of years, tree species in th...

The annual and regular flood pulse is the main hydrologic feature found in the large floodplains along Amazonian rivers triggering nutrient cycles, growth rhythms and life cycles of the biota as well as primary and secondary productivity. The construction of hydroelectric dams in the Amazon basin substantially alters the hydrologic regime resulting...

Fire is an increasingly important agent of forest degradation in the Amazon, but little attention has been given to the susceptibility of seasonally flooded forests to fire. Satellite images suggest that forests flooded seasonally by nutrient-poor black waters are more susceptible to fire and may suffer greater fire damage than nearby upland forest...

A construção de grandes hidrelétricas afeta diretamente a hidrologia dos rios amazônicos, comprometendo o pulso de inundação a jusante da barragem e, por consequência, atingindo as florestas alagáveis que margeiam esses cursos de água.

The monomodal flood pulse is the main driving force for decomposition, nutrient cycles and primary and secondary productivity in the Amazon River floodplains. Flood-tolerant tree species like Macrolobium acaciifolium (Benth.) Benth. (Fabaceae) occupying the lower topographic positions in floodplain forests grow during the lower water levels, and fo...

Nutrient-poor and seasonally flooded Amazon forests have suffered high impacts from forest fires. During the dry periods, seasonally flooded forests can present higher air temperature and lower humidity compared to upland forests, enabling the occurrence and spread of fire. These microclimatic conditions may be related to structural attributes of t...

Surface fires cause forest degradation in the seasonal parts of Amazonia, but upland forests of the more humid Central Amazon suffer little fire damage. Seasonally flooded igapó forests of the central Amazon are an exception, suffering higher fire mortality than upland forest. Here we ask if spectral end members can accurately predict fire effects...
