    Os sambaquis do litoral do Espírito Santo foram pouco estudados pelas pesquisas arqueológicas realizadas no estado. Apesar de serem conhecidos desde finais do século XIX, foram recorrentemente considerados uma extensão marginal dos desenvolvimentos culturais que aconteciam no Rio de Janeiro. À escassez de informações sobre as características dos sítios, soma-se a ausência de datações 14C bem referenciadas, as quais impedem o entendimento da profu…

  • Impact of pre-Columbian “geoglyph” builders on Amazonian forests

    Open Access•Jennifer Watling, J Iriarte et al.•ARTICLE•Proceedings of the National…•2017

    Significance Amazonian rainforests once thought to be pristine wildernesses are increasingly known to have been inhabited by large populations before European contact. How and to what extent these societies impacted their landscape through deforestation and forest management is still controversial, particularly in the vast interfluvial uplands that have been little studied. In Brazil, the groundbreaking discovery of hundreds of geometric earthwor…

  • Análise Isotópica (Δ13c) De Um Cambissolo Húmico Em Abelardo Luz-Sc

    Open Access•Paula Louíse De Lima Felipe, Fernanda Aparecida Cecchet et al.•ARTICLE•Boletim de Geografia•2016

    No período Quaternário, o Sul do Brasil passou por instabilidades paleoclimáticas que geraram mudanças nas paisagens. Estudos pedológicos, sedimentológicos e de reconstrução paleoambiental têm sido desenvolvidos pelo grupo Gênese e Evolução de Superfícies Geomórficas e Formações Superficiais (UNIOESTE-FB) para investigar a hipótese da influência paleoclimática na configuração da paisagem do Sudoeste do Paraná e Noroeste de Santa Catarina. Visando…

  • From an Estuary to a Freshwater Lake

    Open Access•Antonio Alvaro Buso Junior, Luiz Carlos Ruiz Pessenda et al.•ARTICLE•Radiocarbon•2013•Citada por: 3•Referencias: 20

    A sediment core was studied to characterize the influences of Holocene sea-level variations in the Barra Seca River valley, in the Atlantic rainforest, Linhares, Espírito Santo, southeastern Brazil. Biological proxies (pollen, spores, and sponge spicules), 14 C dating, granulometry, δ 13 C, δ 15 N, C/N and major chemical elements revealed the establishment and the evolution of a paleo-estuary during the interval from ∼7700–585 cal BP. During the …

  • Late Pleistocene and Holocene Vegetation, Climate Dynamics, and Amazonian Taxa in the Atlantic Forest, Linhares, SE Brazil

    Open Access•Antonio Alvaro Buso Junior, Luiz Carlos Ruiz Pessenda et al.•ARTICLE•Radiocarbon•2013•Citada por: 3•Referencias: 53

    Analysis of biological proxies in lake sediment and geochemical analysis of soil profiles reveal natural vegetation dynamics, with climate inferences, since the late Pleistocene in a fragment of the pristine lowland Atlantic Forest of southeastern Brazil. Carbon isotopes from soil organic matter and 14 C ages from the humin fraction indicate the dominance of C 3 plants since ∼17,000 cal BP. Palynological analysis of a sediment core indicates the …

  • Morphological and vegetation changes on tidal flats of the Amazon Coast during the last 5000 cal. yr BP

    Open Access•José Tasso F Guimarães, Marcelo C L Cohen et al.•ARTICLE•The Holocene•2012•Referencias: 11

    The analysis of morphology, sedimentary facies, palynology, carbon and nitrogen isotopes, C/N ratio and radiocarbon data from tidal flats sediments influenced by the Amazon River indicates that vegetation development during the last 5000 cal. yr BP was controlled by morphological changes associated with marine and fluvial process. The proximal portion of the tidal flat corresponds to abandoned channels surrounded by terrestrial vegetation since 5…

  • The evolution of a tropical rainforest/grassland mosaic in southeastern Brazil since 28,000 14 C yr BP based on carbon isotopes and pollen records

    Open Access•Luiz Carlos Ruiz Pessenda, Priscila Enrique De Oliveira et al.•ARTICLE•Quaternary Research•2009

    The lack of paleoecological records from the montane Atlantic Rainforest of coastal Brazil, a hotspot of biological diversity, has been a major obstacle to our understanding of the vegetational changes since the last glacial cycle. We present carbon isotope and pollen records to assess the impact of the glaciation on the native vegetation of the Serra do Mar rainforest in São Paulo, Brazil. From ca. 28,000 to ∼ 22,000 14 C yr BP, a subtropical fo…

  • A geochemical and lead isotopic record from a small pond in a remote equatorial island, Fernando de Noronha, Brazil

    A 72 cm long core was collected from Lagoa da Viração (LV), a small pond in the Fernando de Noronha island, northern Brazil. Sediments from the lower section of the core (20—72 cm depth) contain essentially mineral matter, while in the upper section (0—20 cm depth) mineral matter is mixed with organic matter. Lithogenic conservative elements — Si, Al, Fe, Ti, Co, Cr, Cu, Ba, Ga, Hf, Nb, Ni, Y, V, Zn, Zr and REE — exhibit remarkably constant value…

    Carbon isotopes of soil organic matter (SOM) were used to evaluate and establish the chronology of the vegetation dynamics of an ecosystem presently composed of savannas surrounded by forests. The study was carried out on a 200-km transect along highway BR 319, on the border of Amazonas and Rondônia states, in southern Amazon, Brazil. Large ranges in δ 13 C values were observed in SOM collected from profiles in the savanna (−27 to −14‰) and fores…

    Analysis of biological proxies in lake sediment and geochemical analysis of soil profiles reveal natural vegetation dynamics, with climate inferences, since the late Pleistocene in a fragment of the pristine lowland Atlantic Forest of southeastern Brazil. Carbon isotopes from soil organic matter and 14 C ages from the humin fraction indicate the dominance of C 3 plants since ∼17,000 cal BP. Palynological analysis of a sediment core indicates the …

  • Análise Isotópica (Δ13c) De Um Cambissolo Húmico Em Abelardo Luz-Sc

    Open Access•Paula Louíse De Lima Felipe, Fernanda Aparecida Cecchet et al.•ARTICLE•Boletim de Geografia•2016

    No período Quaternário, o Sul do Brasil passou por instabilidades paleoclimáticas que geraram mudanças nas paisagens. Estudos pedológicos, sedimentológicos e de reconstrução paleoambiental têm sido desenvolvidos pelo grupo Gênese e Evolução de Superfícies Geomórficas e Formações Superficiais (UNIOESTE-FB) para investigar a hipótese da influência paleoclimática na configuração da paisagem do Sudoeste do Paraná e Noroeste de Santa Catarina. Visando…

  • Impact of pre-Columbian “geoglyph” builders on Amazonian forests

    Open Access•Jennifer Watling, J Iriarte et al.•ARTICLE•Proceedings of the National…•2017

    Significance Amazonian rainforests once thought to be pristine wildernesses are increasingly known to have been inhabited by large populations before European contact. How and to what extent these societies impacted their landscape through deforestation and forest management is still controversial, particularly in the vast interfluvial uplands that have been little studied. In Brazil, the groundbreaking discovery of hundreds of geometric earthwor…

  • Os primeiros povoadores do litoral norte do Espírito Santo

    Os sambaquis do litoral do Espírito Santo foram pouco estudados pelas pesquisas arqueológicas realizadas no estado. Apesar de serem conhecidos desde finais do século XIX, foram recorrentemente considerados uma extensão marginal dos desenvolvimentos culturais que aconteciam no Rio de Janeiro. À escassez de informações sobre as características dos sítios, soma-se a ausência de datações 14C bem referenciadas, as quais impedem o entendimento da profu…
