                         Floristic and carbon isotopic characterizations of modern plants 
                         were combined with organic matter carbon isotope and grain size 
                         records of soil to characterize vegetation evolution at six 
                         locations on southeastern and northeastern Maraj{\'o} Island and 
                         its relations to climate changes since the late Pleistocene. C3 
                         plants contribute 100% of the biomass in the rainforest on 
                         post-Barreiras sediments (site 1). No significant vegetation 
                         changes are evident in these places since at least ~7860 cal yr 
                         B.P. Rainforests on paleochannels (sites 4 and 6) are protected 
                         from flooding by slightly elevated sandy levee and have flora very 
                         similar to site 1. These forests were formed since the early-mid 
                         Holocene after channel abandonment. C3 grasses are predominant in 
                         open savanna areas (sites 4, 5 and 6), with less representation in 
                         wooded savannas (sites 2 and 3). However, C4 grasses, despite 
                         having fewer species, constitute significant biomass in the wooded 
                         (~60%) and open savanna vegetation areas, especially during the 
                         dry season. The reconstructions of past vegetation together with 
                         the distributions of modern vegetation allow prediction that 
                         climate changes to drier conditions can significantly influence 
                         the future Maraj{\'o} Island landscape, likely enabling expansion 
                         of C4 plants in the flooding zone and of trees in the 
                         rainforests.",
