Resumo: The aim of the present study was to analyze the structure of the phytoplankton community on the nyctemeral and seasonal scales and the influence of limnological variables in two Amazon lakes: Caracaranã Lake (03º50’41” N and 59º46'52.1 W) and Lago dos Reis (01º30’59.5” N and 61º15'50.4" W). Sampling was performed with nictemeral frequency in 4-hour intervals, completing two 24-hour cycles in two distinct climate periods: rainy season (August and September 2005 and June 2006) and dry season (December 2005 and November 2006). Collections were made at a central station in the lakes at the subsurface (0.20 m), middle and approximately 30 cm above the bottom of the water column, using a van Dorn bottle. The following abiotic variables were analyzed: temperature, dissolved oxygen, pH, electrical conductivity, turbidity, total nitrogen, nitrate, total dissolved phosphorus and orthophosphate. The phytoplankton community was assessed with regard to composition and density. The relationship between the phytoplankton community and abiotic variables was assessed using canonical correspondence analysis. Caracaranã Lake proved oxygenated, witha predominance of an ortograde profile, slightly acidic, polymythic waters with diurnal stratification and nocturnal circulation during the rainy season and homogeneous layers during the dry season, with low concentrations of nutrients, characterizing an oligotrophic environment. A total of 60 taxa were identified, with a predominance of desmids (50% of the taxa). The species Botryococcus terribilis J. Komárek & P. Marvan e Sphaerocystis shroeteri Chodat had a 92.86% frequency of occurrence. The nictemeral variations in population densities tended toward the formation of vertical gradients, with slightly higher values at the subsurface. Regarding seasonality, the greatest densities occurred in the rainy season and the lowest densities occurred in the dry season. Lago dos Reis had low concentrations of oxygen, a clinograde profile, waters ranging from slightly acidic to alkaline, stratified during the day and homogenous at night, with low concentrations of nutrients. The phytoplankton community was represented by 54 taxa, with a predominance of Chlorococcales (22 species). Small densities of phytoplankton occurred in both nictemeral cycles, with an accentuatedvertical gradient. The highest densities were recorded in the dry season and lowest densities were recorded in the wet season. Lago dos Reis exhibit characteristics that classify it as apolymythic, oligotrophic environment. The canonical correspondence analysis demonstrated that the variability in the data was more important seasonally than on the nictemeral scale. It was concluded that differences found in the structure and dynamics of the phytoplankton communities are related to the particular characteristics of each lake, such as low concentrations of dissolved oxygen, turbid waters, pH ranging from slightly acidic to alkaline at Lago dos Reis, contrasting the well-oxygenated waster, high transparency and slightly acid pH in Caracaranã Lake.

Foram realizadas amostragens com freqüência nictemerais, em intervalos de 4 horas, completando dois ciclos de 24 horas em dois períodos climatológicos distintos: período chuvoso (agosto e setembro/2005 e junho/2006) e período seco (dezembro/2005 e novembro/2006). As coletas foram feitas em uma estação central dos lagos, na subsuperfície (0,20 m), meio e aproximadamente 30 cm acima do fundo da coluna d’água, utilizando-se garrafa de van Dorn. As variáveis abióticas analisadas foram: temperatura, oxigênio dissolvido, pH, condutividade elétrica, turbidez, nitrogênio total, nitrito, nitrato, fósforo total, fósforo total dissolvido e ortofosfato. A comunidade fitoplanctônica foi avaliada em relação à composição e densidade. A relação entre as variáveis abióticas e a comunidade fitoplanctônica foi avaliada através da análise de correspondênciacanônica (ACC). O lago Caracaranã apresentou-se oxigenado com predomínio de perfil do tipo ortogrado, águas levemente ácidas, polimítico com estratificação diurna e circulação noturna durante o período chuvoso e camada homogênea no período seco e baixas concentrações de nutrientes caracterizando-o como um ambiente oligotrófico. Um total de 60 táxons foi identificado, com predomínio das desmídias (50% dos táxons). As espécies Botryococcus terribilis J. Komárek & P. Marvan e Sphaerocystis shroeteri Chodat apresentaram freqüência de ocorrência de 92,86%. As variações nictemerais de densidades populacionais tenderam à formação de gradientes verticais com valores ligeiramente maiores na subsuperfície. Em relação à sazonalidade, as maiores densidades ocorreram no períodochuvoso e as menores no período seco. O lago dos Reis apresentou águas com baixas concentrações de oxigênio e presença de perfil clinogrado, variando entre levemente ácidas a alcalinas, estratificadas no período diurno e homogêneas no período noturno e baixas concentrações de nutrientes. A comunidade fitoplanctônica esteve representada por 54 táxons, com predomínio das Chlorococcales (22 espécies). Reduzidas densidades fitoplanctônica ocorreram nos dois ciclos nictemerais, com acentuado gradiente vertical. As maioresdensidades foram registradas no período seco e as menores no chuvoso. O lago dos Reis apresenta características que permitem classificá-lo como um ambiente polimítico e oligotrófico. A análise de correspondência canônica mostrou que a variabilidade dos dados foi mais importante sazonalmente do que na escala nictemeral. Em síntese, conclui-se que as diferenças observadas na estrutura e dinâmica da comunidade fitoplanctônica dos lagos estão relacionadas às características peculiares de cada um, tais como, baixas concentrações de oxigênio dissolvido, águas turvas, pH variando de levemente ácido a alcalino do lago dos Reis, contrastando com águas bem oxigenadas, alta transparência e pH levemente ácido do lago Caracaranã.Submitted by (edna.saturno@ufrpe.br) on 2016-06-20T13:59:19Z No. of bitstreams: 1 Ise de Goreth Silva.pdf: 613990 bytes, checksum: c32a4537ad54aa48a78eb629933cc489 (MD5)Made available in DSpace on 2016-06-20T13:59:19Z (GMT).
