Resumo: | Studies on floristic composition are key to understand qualiquantitative changes on phytoplankton assemblages over the year. Spatial-temporal variation in composition, richness, frequency of occurrence, and abundance (semi-quantitative) of the phytoplankton community was analyzed monthly (from April 2002 to May 2003), at 3 stations, in Coqueiro Lake (Pantanal, Mato Grosso, Brazil). We registered 256 taxa, mainly represented by Zygnematophyceae (36%), Chlorophyceae (21%), and Euglenophyceae (14%). The highest abundance occurred at the limnetic station (2), but Bacillariophyceae, Cyanophyceae, Chlorophyceae, and Zygnematophyceae prevailed at the 3 stations. The highest average richness was obtained at the littoral station (3), but this station showed a significantly lower abundance (p < 0.05) than the 2 limnetic stations. The system was characterized for higher contributions of Chlorophyceae in the falling water period, Bacillariophyceae in the low waters, Cyanophyceae in the rising waters and Zygnematophyceae in the high waters, and, on average, the highest richness and abundance were registered in the drought (Aulacoseira spp., Coelastrum spp., Anabaena spp., Aphanocapsa minutissima, Planktolyngbya spp. and Eutetramorus fottii). The attributes of phytoplankton community showed spatial and temporal variations, influenced by the presence of macrophytes, but defined, above all, by seasonal hydrologic changes, caused by the flooding pulse. |

Estudos sobre a composição florística são essenciais para compreender mudanças quali-quantitativas nas assembleias fitoplanctônicas ao longo do ano. A variação espaço-temporal da composição, riqueza, frequência de ocorrência e abundância (semiquantitativa) da comunidade fitoplanctônica foi analisada mensalmente (de abril de 2002 a maio de 2003), em três estações, na baía do Coqueiro (Pantanal, Mato Grosso). Foram registrados 256 táxons, representados principalmente por Zygnematophyceae (36%), Chlorophyceae (21%) e Euglenophyceae (14%). A maior abundância média ocorreu na estação limnética (2), porém, Bacillariophyceae, Cyanophyceae, Chlorophyceae e Zygnematophyceae prevaleceram nas três estações. A maior riqueza média foi obtida na estação litorânea (3), porém, essa estação apresentou abundância significativamente menor (p < 0,05) que as duas estações limnéticas. O sistema caracterizou-se por maiores contribuições de Chlorophyceae no período de vazante, Bacillariophyceae na estiagem, Cyanophyceae na enchente e Zygnematophyceae na cheia, e, em média, a maior riqueza e abundância foram registradas na estiagem (Aulacoseira spp., Coelastrum spp., Anabaena spp., Aphanocapsa minutissima, Planktolyngbya spp. e Eutetramorus fottii). Os atributos da comunidade fitoplanctônica apresentaram variações espaciais e temporais, influenciadas pela presença de macrófitas, mas definidas, sobretudo, pelas mudanças hidrológicas sazonais, causadas pelo pulso de inundaçãoUniversidade Federal de Santa Catarina2015-02-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n2p910.5007/2175-7925.2015v28n2p9Biotemas; v. 28 n. 2 (2015); 9-252175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2015v28n2p9/29239Copyright (c) 2015 Sandra Francisca Marçal, Simoni Maria Loverde-Oliveirainfo:eu-repo/semantics/openAccessMarçal, Sandra FranciscaLoverde-Oliveira, Simoni Maria2017-10-19T16:34:09Zoai:periodicos.ufsc.br:article/35221Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2017-10-19T16:34:09Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
