Resumo: | The Amazon floodplain lakes are subject to yearly fluctuations of water levels and rivers and/or igarapés contributions that have influence in their limnological and biological characteristics. Among the organisms found in the plankton the Pinnularia genus stands out as representative in number of species. This study aims to evaluate the richness of Pinnularia in the Tupé Lake, Rio Negro Basin and its hydrological cycle relation. Samplings with plankton net were carried out in bimonthly scale in three different stations in this lake, covering falling and low waters periods (2002/2003) and the rising and high waters (2003/2004). The results showed that the falling – low waters period presented a significantly higher richness (52 taxa) in comparison to the rising – high waters period, when we observed 33 taxa. The highest richness in the falling – low waters period is probably related to waters coming from “igarapés” and the vertical circulation of the water column, which in this period keeps a greater interface between water-sediment promoting the benthic organisms suspension in the system.Keywords: black waters; diatoms; floodplain lake; South America. |

Dentre os organismos encontrados no plâncton destaca-se o gênero Pinnularia, representativo em número de espécies. O objetivo deste estudo foi avaliar a riqueza de Pinnularia no lago Tupé, Bacia do rio Negro e sua relação com o ciclo hidrológico. Amostragens com rede de plâncton foram realizadas em escala bimestral, em três estações deste lago, englobando os períodos de vazante e águas baixas (2002/2003) e de enchente e águas altas (2003/2004). Os resultados demonstraram que o período de vazante-águas baixas apresentou significativamente maior riqueza (52 táxons) em relação ao período de enchente-águas altas, quando foram registrados 33 táxons. A maior riqueza no período de vazante-águas baixas está provavelmente relacionada à contribuição das águas dos igarapés e à circulação vertical da coluna d´água, que, neste período, se mantêm uma maior interface entre água e sedimento, promovendo a suspensão dos organismos bentônicos no sistema.Palavras-chave: águas pretas, diatomáceas, lago de inundação, América do Sul.Universidade Federal do AmapáCNPqProjeto BiotupeUFOPAPereira, Andreia CavalcanteTorgan, Lezilda CarvalhoMELO, SERGIO2017-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/254110.18561/2179-5746/biotaamazonia.v7n2p15-18Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 7, n. 2 (2017); 8-112179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPporhttps://periodicos.unifap.br/index.php/biota/article/view/2541/v7n2p8-11.pdfAmazônia; Pará; BrasilDireitos autorais 2017 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2017-07-26T23:41:23Zoai:ojs.pkp.sfu.ca:article/2541Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2017-07-26T23:41:23Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false |
