Resumo: Cosmarium is a genus of wide distribution in freshwater environments with great representation in Amazonian aquatic systems. The aim of this study was to determine the taxonomic composition and relative frequency of occurrence of the genus Cosmarium in a clearwater floodplain lake located in the municipality of Santarém, Pará, Amazonia, Brazil. Twenty-eight samples were collected from the limnetic region during low water and high water periods. A total of 16 taxa were recorded of the genus Cosmarium and of this total, six are varieties that are not typical of their respective species. C. contractum var. contractum and C. bioculatum var. bioculatum were the best represented species in the environmented and were recorded in 100% of the samples in the low water period and in more than 50% in the high water period. C. contractum var. retusum and C. pseudopyramidatum var. rotundatum are new records for the state of Pará.Keywords: desmids, taxonomy, amazon diversity, green algae, Amazon floodplain lake

O estudo teve o objetivo determinar a composição taxonômica e frequência de ocorrência relativa do gênero Cosmarium em um lago de inundação de águas claras, localizado no munícipio de Santarém, Pará, Amazônia, Brasil. Foram analisadas 28 amostras, coletadas na região limnética nos períodos de águas baixas (seca) e águas altas (cheia). Um total de 16 táxons foram registrados do gênero Cosmarium e, deste total, seis são variedades que não são as típicas de suas respectivas espécies. C. contractum var. contratum e C. bioculatum var. bioculatum foram as espécies melhor representada no ambiente, tendo sido registrados em 100% das amostras no período de águas baixas e em mais de 50% no período de águas altas. C. contractum var. retusum e C. pseudopyramidatum var. rotundatum são novos registros para o Estado da Pará.Palavras-chave: desmídias, taxonomia, algas verdes, diversidade amazônica, lago de inundação.Universidade Federal do AmapáCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Saturnino, MáizaSophia, Maria da GraçaMELO, SERGIO2020-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo Avaliado pelos Paresapplication/pdfhttps://periodicos.unifap.br/index.php/biota/article/view/536210.18561/2179-5746/biotaamazonia.v10n3p58-64Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota); v. 10, n. 3 (2020); 58-642179-5746reponame:Biota Amazôniainstname:Universidade Federal do Amapá (UNIFAP)instacron:UNIFAPporhttps://periodicos.unifap.br/index.php/biota/article/view/5362/v10n3p58-64.pdfAmazônia; BrasilDireitos autorais 2021 Biota Amazônia (Biote Amazonie, Biota Amazonia, Amazonian Biota)http://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccess2021-01-13T23:24:24Zoai:ojs.pkp.sfu.ca:article/5362Revistahttp://periodicos.unifap.br/index.php/biotaONGhttps://periodicos.unifap.br/index.php/biota/oai||juliosa@unifap.br2179-57462179-5746opendoar:2021-01-13T23:24:24Biota Amazônia - Universidade Federal do Amapá (UNIFAP)false
