abstract = "This work integrates geomorphological, sedimentological, and
palynological data with radiocarbon dating, as well as C-13, N-15,
and C/N from sedimentary organic matter to provide a model of
mangrove dynamics during the evolution of a wave-dominated delta
in Southeastern Brazil. Mangrove dynamics are analyzed within the
context of millennial and secular climatic and sea-level changes.
Tidal flats, positioned at highest limit of the intertidal zone
along the edge of a lagoon sheltered by beach ridges, were
occupied by wetlands represented by mangrove and herbaceous
vegetation during the mid-Holocene high sea level. After
considering the relative sea-level fall and relatively higher
fluvial sediment discharge, during the last similar to 6350years,
progradation took place along this shoreline, resulting in
extensive beach ridge deposits that overlie transgressive muds.
This process led to loss of mangrove area. Similar dynamics were
repeated at similar to 3043cal. yr BP, although in a relatively
more distal (i.e. seaward) position. Between similar to 1337 and
similar to 900cal. yr BP, a tidal flat attached to the edge of a
lagoon near the modern coastline was colonized by herbaceous
vegetation (C4 plants). The next phase, which occurred between
similar to 900 and similar to 400 or similar to 100cal. yr BP, is
marked by the transition from herbaceous to mangrove tidal flats
with an increased trend of terrestrial organic matter. During the
recent centuries, a mangrove vegetation became established, and
there was an increased trend of estuarine-derived organic matter.
This mangrove phase, recorded during the last century(ies), may be
due to a relative sea-level rise. Under this scenario, erosion of
beach ridges and expansion of lagoons and mangroves are expected
along the littoral of the State of Espirito Santo in Southeastern
Brazil.",
