             abstract = "The Amazon floodplain ecosystem links large-scale climatic 
                         phenomena to the lives of animals (including people), plants, and 
                         other organisms that live within it. The floodplain is subject to 
                         seasonal changes in water level that can reach up to 16m, as it 
                         aggregates rainfall inputs from the entire Amazon basin. The 
                         amount and distribution of such rain is related to annual 
                         variations in the Tropical Atlantic and Pacific Oceans sea surface 
                         temperatures. On the other hand, the assemblies of species that 
                         are found within the floodplain depend to a large extent on 
                         flooding dynamics. Moreover, floodplains of the major rivers are 
                         home to over 70% of the human population living in the Amazon. 
                         Within them people fish, raise cattle, grow crops, transport 
                         goods, and have leisure. People depend on its biodiversity, though 
                         several species have already had their populations drastically 
                         depleted due to over-hunting and over-fishing. To contribute to 
                         the understanding of how the predicted increases in the frequency 
                         of droughts and other extreme climatic events in the Amazon will 
                         impact the floodplains present biodiversity, and its 
                         biogeochemistry, it is thus necessary to understand the dynamics 
                         of the floodplain ecosystem. Here, we begin such investigation 
                         from a large-scale perspective. We consider the land cover 
                         characteristics of the floodplain (woody vegetation, annual 
                         herbaceous vegetation, and open water), and how its spatial and 
                         temporal dynamics are related to the flood cycle. We use 
                         multi-scale analysis of remote sensing datasets, geographical 
                         information systems, hydrograph analyses, fieldwork and several 
                         analytical techniques. Preliminary results show that cover types 
                         with faster dynamics, such as macrophyte assemblies, respond 
                         quickly to extreme droughts. Impacts on these habitats might be 
                         carried over to other components of the system, thus influencing 
                         carbon fixation and transformation, animal migration patterns, and 
                         fish abundance and availability.",
