                         changes, four sediment cores were collected from the northern 
                         Brazilian Amazonia lowland. These cores were studied through 
                         pollen analysis and sedimentary features, and the results were 
                         discussed within a chronological framework provided by radiocarbon 
                         dating. The cores were sampled from fluvial terraces 
                         representative of channel, floodplain/lake and crevasse splay 
                         deposits formed since the mid-Holocene. The pollen samples derive 
                         from floodplain/lake deposits and the pollen grains are mainly 
                         composed by families Moraceae, Euphorbiaceae, Caesalpiniaceae, 
                         Fabaceae, Rubiaceae, Melastomataceae, Combretaceae, Sapindaceae, 
                         Poaceae, Cyperaceae, Aizoaceae, Apiaceae and genus Sebastiana. The 
                         pollen data suggest no significant vegetation changes in the study 
                         area for the past 48084886 cal yr BP. This led to proposing stable 
                         climatic conditions since at least the middle Holocene. Such a 
                         finding is contrary to the occurrence of a dry period during the 
                         middle Holocene. The stabilization of the relative sea level about 
                         6000 cal yr BP along the northern Brazilian littoral may have 
                         influenced the water table, and favored the establishment and 
                         maintenance of Amazonian lowland forest during the mid- and late 
                         Holocene. In addition, this process may have attenuated the impact 
                         of that dry period in areas under most fluvial influence.",
