Resumo: | In the semiarid region, the reservoirs perform important role for the regional development, which results in the increase of the anthropogenic pressure, causing changes in the water quality. The knowledge of the zooplankton structure supplies basic information for the ecology, zoology, limnology and biogeography of these organisms. The objective of this study was to characterize the plankton microcrustaceans assemblage (Copepoda and Cladocera) in the Pedra Dam Reservoir (PDR) in two distinct periods (rainy and dry/2003). The samplings were carried out in four station of the PDR, using plankton net (70µm of mesh), by vertical hauls from the bottom until the surface, and preserved in formaldehyde 4%. A total of 12 species of microcrustaceans were identified. The dominant species were Notodiaptomus iheringi and Daphnia gessneri. Adult density ranged from 4303 to 7423 ind.m-3 in January and from 669 to 7272 ind.m-3 in July. Shannon diversity index varied from 1.90 bits.ind-1 in July to 2.71 bits.ind-1 in January. Higher densities of individuals, diversity index and equitability were found during rainy season. The structure of the microcrustaceans assemblage differed between rainy and dry seasons and was significantly correlated with the physical and chemical water variables. |

O conhecimento do zooplâncton fornece informações básicas sobre a estrutura trófica pelágica. O objetivo deste trabalho foi caracterizar a assembléia de microcrustáceos planctônicos (copépodes e cladóceros) no reservatório Barragem da Pedra, em dois períodos distintos (chuvoso e seco/2003). As amostragens foram realizadas em quatro pontos do Reservatório Barragem de Pedra, com uma rede de plâncton (malha de 70 µm), por meio de arrastos verticais do fundo para a superfície. Foram encontradas 12 espécies de microcrustáceos. As espécies dominantes foram Notodiaptomus iheringi e Daphnia gessneri. A densidade de indivíduos adultos variou de 4.303 a 7.423 ind. M-3 em janeiro e de 669 a 7.272 ind. M-3 em julho. O índice de diversidade de Shannon variou de 1,90 bit. ind.-1 em julho a 2,71 bit. ind.-1 em janeiro. Maiores densidades de indivíduos, índice de diversidade e equabilidade foram encontrados na estação chuvosa. A estrutura da comunidade de microcrustáceos diferiu entre as estações seca e chuvosa e correlacionou-se significativamente com as variáveis físicas e químicas da água.Universidade Estadual De Maringá2009-04-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciBiolSci/article/view/53810.4025/actascibiolsci.v31i1.538Acta Scientiarum.
