Resumo: | Small ponds are vital inland water bodies, recognized as small repositories of freshwater biodiversity, but neglected in terms of conservation. Although high-elevation ponds are difficult to sample and monitor, it is important to extend their study, in view of their importance to aquatic biodiversity. The aim of this study was to analyze the composition, size structure biomass and diversity of zooplankton community in a temporary pond (Lagoa Seca) of a low-alpine area in the southern part of Serra do Espinhaço mountain in Minas Gerais State, Brazil. Three ecological aspects were analyzed: (I) the taxonomic composition of the zooplankton assemblage, (II) the size structure and biomass of the main groups in the zooplankton community and (III) whether the morphometric characteristics and biomass of the zooplankton result from the dominance of the microzooplankton, as expected in habitats subjected to frequent and strong disturbances, such as temporary ponds. Zooplankton samples were taken during the rainy period (OcÂtober 2010 to January 2011) in different mesohabitats, from the shallowest areas covered by emergent macrophytes to the open water area covered mainly by submerged macrophytes. The zooplankton community consisted of a small number of taxa (29). Rotifera showed the highest richness, with 21 taxa recorded, of which the most constant species were the cosmopolitan Lecane lunaris, L. obtusa and Lepadella patella. Among the Cladocera, Bosmina freyi and Moina minuta were the pelagic species recorded. The other cladoceran species observed are associated with littoral vegetation, and represented mainly by Alona ossiani, Chydorus pubescens, Ephemeroporus tridentatus and Ilyocryptus spinifer. The zooplankton biomass was very low (the maximum dry weight, observed at the peak of the rainy period in January was 62 ?g.m-3). The zooplankton community was dominated by the microzooplankton, with the maximum body length below 900 ?m. This assemblage was very changeable in the short term, both in numerical density and size structure, probably because of the highly variable hydrological regime of the pond. The results from zooplankton composition, including the first record of the rotifer Microcodon clavus to Minas Gerais state and the second in Brazil, highlighted the important role that high-elevation temporary ponds can play as aquatic biodiversity reserves. These unique ecosystems deserve greater efforts of research and monitoring, including studies of their hydrological patÂterns, biological diversity, and adaptive mechanisms of the zooplankton community. |

Embora lagoas de alta altitude sejam de difícil amostragem e monitoramento, é importante ampliar seu estudo, tendo em vista sua importância para a biodiversidade aquática. O objetivo deste estudo foi analisar a composição, estrutura de tamanho, biomassa e diversidade da comunidade zooplanctônica em uma lagoa temporária (Lagoa Seca) de uma área de baixa altitude na parte sul da Serra do Espinhaço em Minas Gerais, Brasil. Três aspectos ecológicos foram analisados: (I) a composição taxonômica da assembleia zooplanctônica, (II) a estrutura de tamanho e biomassa dos principais grupos da comunidade zooplanctônica e (III) se as características morfométricas e a biomassa do zooplâncton resultam da dominância do microzooplâncton, como esperado em habitats sujeitos a perturbações frequentes e fortes, como lagoas temporárias. Amostras de zooplâncton foram coletadas durante o período chuvoso (outubro de 2010 a janeiro de 2011) em diferentes mesohabitats, desde as áreas mais rasas cobertas por macrófitas emergentes até as áreas de águas abertas cobertas principalmente por macrófitas submersas. A comunidade zooplanctônica consistia em um pequeno número de táxons (29). Rotifera apresentou a maior riqueza, com 21 táxons registrados, dos quais as espécies mais constantes foram as cosmopolitas Lecane lunaris, L. obtusa e Lepadella patella. Entre os Cladocera, Bosmina freyi e Moina minuta foram as espécies pelágicas registradas. As demais espécies de cladóceros observadas estão associadas à vegetação litorânea, sendo representadas principalmente por Alona ossiani, Chydorus pubescens, Ephemeroporus tridentatus e Ilyocryptus spinifer. A biomassa zooplanctônica foi muito baixa (o peso seco máximo, observado no pico do período chuvoso em janeiro foi de 62 ?g.m-3). A comunidade zooplanctônica foi dominada pelo microzooplâncton, com comprimento corporal máximo abaixo de 900 ?m. Esta assembleia foi muito variável no curto prazo, tanto na densidade numérica quanto na estrutura de tamanho, provavelmente devido ao regime hidrológico altamente variável da lagoa. Os resultados da composição do zooplâncton, incluindo o primeiro registro do rotífero Microcodon clavus para Minas Gerais e o segundo para o Brasil, destacaram o importante papel que lagoas temporárias de alta altitude podem desempenhar como reservas de biodiversidade aquática. Esses ecossistemas únicos merecem maiores esforços de pesquisa e monitoramento, incluindo estudos de seus padrões hidrológicos, diversidade biológica e mecanismos adaptativos da comunidade zooplanctônica.engUniversidade Federal de Minas GeraisUFMGBrasilBIU - BIBLIOTECA UNIVERSITARIAOecologia australisQuadrilátero de FerroMontanhaLago rasoComunidade de zooplânctonComposition, body-size structure and biomass of zooplankton in a high-elevation temporary pond (Minas gerais, Brazil)Composição, estrutura corporal e biomassa do zooplâncton em uma lagoa temporária de alta altitude (Minas Gerais, Brasil)info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://revistas.ufrj.br/index.php/oa/article/view/8361Raquel Aparecida MoreiraOdete RochaRenata Martins Dos SantosEmerson Silva DiasFrancisco Wagner Araujo MoreiraEneida Maria Eskinazi Santannaapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/43109/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINAL2016_Composition, body-size structure and biomass of zooplankton in a high-elevation temporary pond (minas gerais, brazil).pdf2016_Composition, body-size structure and biomass of zooplankton in a high-elevation temporary pond (minas gerais, brazil).pdfapplication/pdf1180473https://repositorio.ufmg.br/bitstream/1843/43109/2/2016_Composition%2c%20body-size%20structure%20and%20biomass%20of%20zooplankton%20in%20a%20high-elevation%20temporary%20pond%20%28minas%20gerais%2c%20brazil%29.pdf967701bfac5a4b55824516bf92169d92MD521843/431092022-07-08 17:33:05.774oai:repositorio.ufmg.br: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Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2022-07-08T20:33:05Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |

Small ponds are vital inland water bodies, recognized as small repositories of freshwater biodiversity, but neglected in terms of conservation. Although high-elevation ponds are difficult to sample and monitor, it is important to extend their study, in view of their importance to aquatic biodiversity. The aim of this study was to analyze the composition, size structure biomass and diversity of zooplankton community in a temporary pond (Lagoa Seca) of a low-alpine area in the southern part of Serra do Espinhaço mountain in Minas Gerais State, Brazil. Three ecological aspects were analyzed: (I) the taxonomic composition of the zooplankton assemblage, (II) the size structure and biomass of the main groups in the zooplankton community and (III) whether the morphometric characteristics and biomass of the zooplankton result from the dominance of the microzooplankton, as expected in habitats subjected to frequent and strong disturbances, such as temporary ponds. Zooplankton samples were taken during the rainy period (OcÂtober 2010 to January 2011) in different mesohabitats, from the shallowest areas covered by emergent macrophytes to the open water area covered mainly by submerged macrophytes. The zooplankton community consisted of a small number of taxa (29). Rotifera showed the highest richness, with 21 taxa recorded, of which the most constant species were the cosmopolitan Lecane lunaris, L. obtusa and Lepadella patella. Among the Cladocera, Bosmina freyi and Moina minuta were the pelagic species recorded. The other cladoceran species observed are associated with littoral vegetation, and represented mainly by Alona ossiani, Chydorus pubescens, Ephemeroporus tridentatus and Ilyocryptus spinifer. The zooplankton biomass was very low (the maximum dry weight, observed at the peak of the rainy period in January was 62 ?g.m-3). The zooplankton community was dominated by the microzooplankton, with the maximum body length below 900 ?m. This assemblage was very changeable in the short term, both in numerical density and size structure, probably because of the highly variable hydrological regime of the pond. The results from zooplankton composition, including the first record of the rotifer Microcodon clavus to Minas Gerais state and the second in Brazil, highlighted the important role that high-elevation temporary ponds can play as aquatic biodiversity reserves. These unique ecosystems deserve greater efforts of research and monitoring, including studies of their hydrological patÂterns, biological diversity, and adaptive mechanisms of the zooplankton community. |
