The integration of stratigraphic and
palynological data with radiocarbon dating has allowed the identification of
two periods characterized by low inundation frequency during the last 1000
years in the mangroves of the Braganc¸a Peninsula in North
Brazil. The first event extended over a period of 380 years and
took place between 1130 and 1510 AD. The second began about 1560 AD and
probably finished at the end of the 19th century. These two events are
temporally correlated with the so-called Little Ice Age period, and may reflect
a sea-level regression and/or drier conditions with less rainfall. The study
also indicates that mangroves on the Braganca
Peninsula have been
migrating to higher elevation zones during the last decades, suggesting a relative
sea-level rise. This increase can be associated with the global tendency
towards a eustatic sea-level rise, due to the increase in temperature and
glaciers melting around the world during the last 150 years.
