                         Delta, southeastern Brazil, through a multi-proxy approach that 
                         links palynology, diatoms, sedimentology and geochemistry analyses 
                         (i.e., Total C, Total N, \δ13C and \δ15N). These 
                         analyses, temporally synchronized with five radiocarbon ages, 
                         revealed environmental changes from marine to continental over the 
                         last \∼ 7550 years. The studied sedimentary succession 
                         recorded the upward transition from estuarine channel (until ~ 
                         7550 cal yr BP) to estuarine central basin (>~ 7550 to ~ 5250 cal 
                         yr BP) deposits, the latter containing increased mangrove 
                         vegetation, marine and marine/brackish water diatoms. The range of 
                         geochemical values (\δ13C = \− 30\− 10, 
                         \δ15N = 2 \− 8 and C/N = 440) also indicate 
                         marine/estuarine organic matter and C3 terrestrial plants to that 
                         time interval. A following period recorded two phases: lake/ria (~ 
                         5250 to ~ 400 cal yr BP) and fluvial channel (~ 400 cal yr BP 
                         until modern age). During this stage, mangroves were replaced by 
                         trees/shrubs and herbs/grasses due to the disconnection with the 
                         marine realm. As a result, the corresponding sediments contain 
                         only organic matter sourced from freshwater and C3 terrestrial 
                         plants (\δ13C = \− 29\− 26, \δ15N = 0 
                         \− 8 and C/N = 1045). The equilibrium between fluvial 
                         sediment supply and relative sea-level changes during the Holocene 
                         controlled the morphologic and vegetation changes in the studied 
                         littoral. The estuary became established during the early Holocene 
                         as a resulted of a eustatic sea-level rise, when the fluvial 
                         sediment supply to the coast was relatively lower due to a dry 
                         period. However, during the late Holocene, the climatic force was 
                         more significant to the development of coastal morphology due to a 
                         wet period that caused an increase in sandy sediment supply to 
                         coastal system. Then, the increase of fluvial discharge associated 
                         to a relative sea-level fall caused a marine regression and 
                         shrinkage of mangroves during the late Holocene. The evaluation of 
                         mangrove dynamics according to climatic and sea-level changes 
                         mainly during the late Holocene is essential for the understanding 
                         of their survival ability under future scenarios, with a probable 
                         accelerated sea-level rise and intensification of extreme climatic 
                         events in southeastern Brazil for the next century.",
