Mangrove vegetation changes on Holocene terraces of the Doce River, southeastern Brazil

A multi-proxy evidence for the transition from estuarine mangroves to deltaic freshwater marshes, Southeastern Brazil, due to climatic and sea-level changes during the late Holocene

“…This high RSL led to the reactivation of paleo-estuaries, formed during the penultimate marine transgression (120 k yr BP), and formation of numerous lagoons along the coast of southeastern Brazil. Thus, the early to middle Holocene transgression reported in the present study, and also in other recent studies Castro et al, 2013;França et al, 2013), agrees with the overall eustatic behavior. After this sea-level maximum, the sea-level dropped to the present level time (Angulo et al, 2006).…”

“…The sedimentary organic matter was sourced from marine and estuarine DOC. The marine influence during the early and middle Holocene attests a RSL rise, as recorded by Buso , Castro et al (2013) and França et al (2013).…”

“…Since about 5250 cal yr BP, the estuarine system has been replaced by a lake/ria environment, with the closure of the estuary, the mangrove ecosystem became extinct at the study site, but it remained in a distal position with lower topographies (core Li32), as showed by França et al (2013) (Fig. 4b).…”

“…Climate changes and sea-level oscillations have caused significant impacts on coastal sedimentary dynamics and ecosystems along the Brazilian littoral during the late Quaternary (Suguio et al, 1985;Dominguez et al, 1992;Ledru et al, 1996;Angulo and Lessa, 1997;Behling et al, 1998b;Grimm et al, 2001;Bezerra et al, 2003;Martin et al, 2003;Cohen et al, 2005a,b;Angulo et al, 2006;Vedel et al, 2006;Behling et al, 2007;Sawakuchi et al, 2008;Lara and Cohen, 2009;Zular et al, 2013;Guimarães et al, 2012Guimarães et al, , 2013Buso Junior et al, 2013;França et al, 2012França et al, , 2013França et al, , 2014.…”

Application of stable isotopes to examine N proportions within a simulatedAegiceras corniculatumwetland

“…Stable C isotopic composition, C:N and other indicators have been applied in food web studies of mangrove ecosystems, including biogeochemical cycles (such as belowground ecosystem C cycling), and other ecological processes, as well as the paleoenvironmental reconstruction, sea level rise, paleoclimate change, paleosalinity, and other study topics [12][13][14][15][16][17][18][19][20][21]. The use of δ 13 C can reflect the long-term integrated physiological processes in plants, and has a certain degree of correlation with salinity; therefore the plant δ 13 C can be seen as a characteristic indicator of physiological responses in the presence of changes in environmental factors [22].…”
