| Abstract | The Piraquê-Açu and Piraquê-Mirim estuarine system
(PAPMES) is located next to the Aracruz City (19˚ 57' S and
40˚ 9' W), Espírito Santo State, Brazil. Palynological analyses
were conducted based on two sediment cores (PA20 and
PM1). The main purpose of the present study was to
recognize and interpret the vegetation dynamics in the region
around the collection site in the last 2000 cal yrs BP. The
sediment cores were subsampled at each 10 cm depth. The
samples were submitted to standard palynological processes.
The PA20 sediment core obtained the oldest age of 1758±68
cal yrs BP at a depth of approximately 105-cm. However, the
PM1 sediment core obtained the oldest age of ≈2071±82 cal
yrs BP at a depth of 95-cm. The comparative record of the
sediment cores demonstrated that palynomorphs deposition
were directly influenced by local water circulation. Pollen
analysis indicated the striking presence of mangrove
vegetation, which is mainly characterised by the Rhizophora
pollen type. The other vegetation communities underwent
little variation over the studied period. The top sediment
layers of both sediment cores are characterized by the
presence of exotic pollen grains of Eucalyptus, introduced by
humans, and by the decrease of the original vegetation. | pt_BR |
