Resumo: | In hypersaline environments the zooplankton community is generally poor in density and richness, even so these organisms are fundamental to the base of the local food chain. This study aims to evaluate the spatial and temporal variation of the zooplankton community of Araruama Lagoon, considering the abiotic data of salinity and temperature as well as the biotic data of zooplankton density and composition. Six samples were performed in 12 collection stations from horizontal surface halls with 200 ?m mesh nets with a 60 cm diameter opening and an attached flowmeter. A total of 34 holoplanktonic taxa and five groups of meroplankton were identified. In relation to the spatial and temporal variation of the zooplankton of the lagoon, the parameters evaluated showed significant results for both factors. The variations also showed greater richness, diversity and density of species in the collection stations closer to the sea, where salinity was lower. There was a predominance of holoplankton during the study, differing from the results previously found in the 90’s. |

O presente estudo tem como objetivo avaliar a variação espacial e temporal da comunidade zooplanctônica da Lagoa de Araruama, considerando os dados abióticos de salinidade e temperatura e os dados bióticos densidade e composição do zooplâncton. Foram realizadas seis amostragens em 12 estações de coleta a partir de arrastos de superfície horizontais, utilizando redes de malha de 200 ?m com uma abertura de 60 cm de diâmetro e um medidor de vazão acoplado. Foram identificados um total de 34 táxons holoplanctônicos e cinco grupos de meroplâncton. Em relação a variação espacial e temporal do zooplâncton da lagoa, os parâmetros avaliados apresentaram resultados significativos para ambos os fatores. As variações também apresentaram maior riqueza, diversidade e densidade de espécies nas estações de coleta mais próximas do mar, onde a salinidade foi mais baixa. Houve predominância do holoplâncton durante o estudo, diferente dos resultados encontrados na década de 90.Universidade Federal de Santa Catarina2020-09-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2020.e7024610.5007/2175-7925.2020.e70246Biotemas; v. 33 n. 3 (2020); 1-102175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2020.e70246/44085Copyright (c) 2020 Judson Cruz Lopes Rosa, Lucas Lemos Batistainfo:eu-repo/semantics/openAccessRosa, Judson da Cruz Lopes daBatista, Lucas Lemos2020-09-29T09:40:54Zoai:periodicos.ufsc.br:article/70246Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2020-09-29T09:40:54Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |

This study aims to evaluate the spatial and temporal variation of the zooplankton community of Araruama Lagoon, considering the abiotic data of salinity and temperature as well as the biotic data of zooplankton density and composition. Six samples were performed in 12 collection stations from horizontal surface halls with 200 ?m mesh nets with a 60 cm diameter opening and an attached flowmeter. A total of 34 holoplanktonic taxa and five groups of meroplankton were identified. In relation to the spatial and temporal variation of the zooplankton of the lagoon, the parameters evaluated showed significant results for both factors. The variations also showed greater richness, diversity and density of species in the collection stations closer to the sea, where salinity was lower. There was a predominance of holoplankton during the study, differing from the results previously found in the 90’s. |
