Resumo: | In September 2010 five sediment samples were collected along the estuary of the Arade River aimed to identify environmental compartments based on the distribution of foraminifera species and their relationship with physic-chemical, sedimentological and geochemistry parameters. In the estuary were identified 39 foraminifera species, from wich 31 were calcareous species and 8 agglutinated species that which showed the great species richness values in Arade Estuary. The dominant species were Ammonia tepida and Haynesina germanica that were identified in all sample stations. The mouth of estuary showed the highest values of richness of specimens (31) and diversity (2.73) that demonstrated the strong marine influence in this region. Applying DAC multivariate analysis was possible to identify three areas in the estuary: Section A - region of greater marine influence that has a high concentration of inorganic carbon, sandy sediment and a large number of exotic species transported from adjacent platform (Cibicides bertheloti, Asterigerinata mammila, Bolivina ordinaria and Bolivina elongata); Sector B - middle region of the estuary with muddy sediment, high organic carbon and consists of species typical of estuaries. Sector C - more confined region of the estuary, with muddy sediment, higher concentration of organic carbon in relation to sector B, which is represented by species of agglutinated foraminifera and Ammonia parkinsoniana. |

Foram identificadas 39 espécies de foraminíferos, sendo 31 espécies calcárias e 8 espécies aglutinantes, o que demonstra uma grande riqueza de espécies no estuário. As espécies dominantes foram Ammonia tepida e Haynesina germanica que foram identificadas em todas as estações amostrais. A região da foz do estuário apresentou maior riqueza de espécimes (31) e maior diversidade (2,73) demonstrando a forte influência marinha nesta região. Aplicando a análise multivariada em DAC foi possível identificar três setores no estuário: Setor A - região de maior influência marinha que apresenta alta concentração de carbono inorgânico, sedimento arenoso e um grande número espécies exóticas transportadas da plataforma adjacente (Cibicides bertheloti, Asterigerinata mammila, Bolivina ordinaria and Bolivina elongata); Setor B - região intermediária do estuário com sedimento lamoso, carbono orgânico elevado e composto por espécies típicas de estuários. Setor C - região mais confinada do estuário, com sedimento lamoso, maior concentração de carbono orgânico em relação ao setor B, que é representado por espécies de foraminíferos aglutinantes e Ammonia parkinsoniana.Universidade Federal do Rio de JaneiroLaut, Lazaro Luiz MattosCabral, Isis de AlmeidaRodrigues, Maria Antonieta da ConceiçãoSilva, Frederico SobrinhoMartins, Maria Virgínia AlvesBoski, TomaszGomes, Ana IsabelDias, João Manuel AlverinhoFontana, Luiz FranciscoLaut, Vanessa MattosMendonça-Filho, João Graciano de2017-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufrj.br/index.php/aigeo/article/view/782310.11137/2014_2_60_74Anuário do Instituto de Geociências; Vol 37, No 2 (2014); 60-74Anuário do Instituto de Geociências; Vol 37, No 2 (2014); 60-741982-39080101-9759reponame:Anuário do Instituto de Geociências (Online)instname:Universidade Federal do Rio de Janeiro (UFRJ)instacron:UFRJporhttps://revistas.ufrj.br/index.php/aigeo/article/view/7823/6304Copyright (c) 2014 Anuário do Instituto de Geociênciashttp://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2022-11-26T20:52:28Zoai:www.revistas.ufrj.br:article/7823Revistahttps://revistas.ufrj.br/index.php/aigeo/indexPUBhttps://revistas.ufrj.br/index.php/aigeo/oaianuario@igeo.ufrj.br||1982-39080101-9759opendoar:2022-11-26T20:52:28Anuário do Instituto de Geociências (Online) - Universidade Federal do Rio de Janeiro (UFRJ)false |
