                         proxy for paleoenvironmental reconstructions. A 192 cm lacustrine 
                         sediment core (~7521 cal yr. B.P.) from the northern coast of the 
                         State of Esp{\'{\i}}rito Santo, southeastern Brazil, was 
                         radiocarbon dated and then analyzed for palynofacies, stable 
                         isotopes (C and N), and grain size. The values for total organic 
                         carbon TOC (1.91% to 20.89%), total nitrogen TN (0.08% to 1.1%), 
                         \δ13C (\−27.10 to \−29.01), \δ15N (1.92 
                         to 5.09) and C/N (12.87 to 50.11) suggest predominance of C3 
                         plants and changing mixtures of terrestrial and aquatic organic 
                         matter in the sediments. Palynofacies and cluster analyses were 
                         used to identify four palynofacies associations that reflect 
                         different phases in the Lake Macuco evolution. Palynofacies 1 (192 
                         to 106 cm, ~7521 cal yr. B.P. to ~7054 cal yr. B.P.interpolated 
                         age) is characterized mainly by amorphous organic matter (AOM), 
                         non-opaque phytoclasts (NOPs), mangrove pollen grains (Rhizophora 
                         sp. L. 1753 and Avicennia sp. L. 1753), and foraminiferal test 
                         linings. Palynofacies 2 (106 to 65 cm, ~7054 cal yr. 
                         B.P.interpolated age to ~4847 cal yr. B.P.) is dominated by NOPs 
                         and AOM, with an increase in the values of mangrove pollen grains 
                         relative to Palynofacies 1. Both palynofacies reflect marine and 
                         fluvial influences in a depositional environment related to the 
                         development of an estuarine system during the mid-Holocene 
                         transgressive stage. Palynofacies 3 (65 to 27 cm, ~4847 cal yr. 
                         B.P. to ~3800 cal yr. B.P.interpolated age) comprises high 
                         abundances of fluvial elements (NOP and opaque phytoclastsOP) and 
                         low values of AOM. The depositional environment is interpreted as 
                         being an estuary during the marine regression, with the 
                         displacement of the estuarine basin and mangroves towards the sea. 
                         Palynofacies 4 (27 to 0 cm, b~3800 cal yr. B.P.) is characterized 
                         by the predominance of AOM and NOP, increase in the values of 
                         freshwater algae, and no evidence of marine influence. This last 
                         phase reflects the beginning of the establishment of Lake Macuco 
                         and floodplain of the Barra Seca River under conditions similar to 
                         the present-day.",
