The communities that inhabit these lakes suffer from this influence and are adapted to this change.The studies performed in the Amazon that have analyzed the effects of water level variation in planktonic copepods community were conducted in varzea lakes, which have different characteristics of black water lakes, these studies are limited to monthly and fortnightly collections during high and low water periods. This work’s purpose was oevaluate the effect of the Negro river (black waters) in the composition, richness and abundance of species of planktonic copepods in Tupé lake. Quantitative samples of the limnetic region, in three sampling stations in the lake were taken daily during January, February and March 2011. In the first 10 sampling days there was no influence of the river and on the 11th day of the Negro river waters begin to flood. A total of 14 taxons of copepods were recorded, (Oithona amazonica, Macrocyclops albidus albidus, Mesocyclops brasilianus, Metacyclops brauni, Thermocyclops sp., Aspinus acicularis, Rhacodiaptomus retroflexus, Rhacodiaptomus calatus, Rhacodiaptomus calamensis, Dasydiaptomus coronatus, Dactylodiaptomus pearsei, Notodiaptomus inflatus, Notodiaptomus coniferoides, Diaptomus linus). Diaptomidae was the most representative with 9 species, followed by Cyclopidae who presented four species and Oithonidae with only one representative. The specie Oithona amazonica was the most abundant throughout the study, with ist maximum abundance occurring in the lake's isolation period. The most abundant specie of Calanoida was Aspinus acicularis which also showed higher abundance in the lake's isolation period. The entrance of the Negro river waters negatively influenced the abundance of adult copepods and there was also a decrease in nauplii and copepodites density. However, the diversity and species richness increased during the rising water period. Nas planícies de inundação a variação do nível da água do rio principal influencia o nível da água de lagos adjacentes ao rio e demais rios da bacia hidrográfica. As comunidades que habitam esses lagos sofrem com essa influência e estão adaptados a essa mudança. Na Amazônia os estudos que analisaram os efeitos da variação do nível das águas na comunidade de copépodes planctônicos foram realizados em lagos de várzea, que apresentam características diferentes dos lagos de água preta, e os mesmos restringem-se a coletas mensais ou quinzenais durante os períodos de seca/enchente. O objetivo deste trabalho foi avaliar o efeito da enchente do rio Negro (águas pretas) na composição, riqueza e abundância das espécies de copépodes planctônicos no lago Tupé. Foram utilizadas amostras quantitativas diárias da região limnética de três estações amostrais no lago. O período de amostragem compreendeu os meses de Janeiro, Fevereiro e Março de 2011. Nos 10 primeiros dias de amostragem não há entrada da água do rio no lago, e a partir do 11° dia as águas do rio Negro começam a entrar no lago. Um total de 14 táxons de copépodes foram registrados, (Oithona amazonica, Macrocyclops albidus albidus, Mesocyclops brasilianus, Metacyclops brauni, Thermocyclops sp., Aspinus acicularis, Rhacodiaptomus retroflexus, Rhacodiaptomus calatus, Rhacodiaptomus calamensis, Dasydiaptomus coronatus, Dactylodiaptomus pearsei, Notodiaptomus inflatus, Notodiaptomus coniferoides, Diaptomus linus). Diaptomidae foi a mais representativa com 9 espécies, seguida da Cyclopidae que apresentou 4 espécies e Oithonidae apenas um representante. A espécie Oithona amazonica foi a espécie de Cyclopoida mais abundante durante todo o período de estudo, e de Calanoida foi Aspinus acicularis, a máxima abundância das duas espécies ocorreram no período anterior a entrada da água do rio Negro. A entrada da água do rio Negro influenciou negativamente a abundância de copépodes adultos, houve também diminuição na densidade de náuplius e copepoditos. Entretanto, a diversidade e riqueza de espécies aumentou no decorrer da enchente. 2020-02-13T18:22:11Z 2020-02-13T18:22:11Z 2013-07-24 Dissertação https://repositorio.inpa.gov.br/handle/1/11327 http://lattes.cnpq.br/1736568141282860 por Attribution-NonCommercial-NoDerivs 3.0 Brazil http://creativecommons.org/licenses/by-nc-nd/3.0/br/ application/pdf Instituto Nacional de Pesquisas da Amazônia - INPA Biologia de Água Doce e Pesca Interior - BADPI |

| description |
In the floodplain the variation of the main river water level influences the water level of lakes
adjacent to the river. The communities that inhabit these lakes suffer from this influence and
are adapted to this change.The studies performed in the Amazon that have analyzed the
effects of water level variation in planktonic copepods community were conducted in varzea
lakes, which have different characteristics of black water lakes, these studies are limited to
monthly and fortnightly collections during high and low water periods. This work’s purpose
was oevaluate the effect of the Negro river (black waters) in the composition, richness and
abundance of species of planktonic copepods in Tupé lake. Quantitative samples of the
limnetic region, in three sampling stations in the lake were taken daily during January,
February and March 2011. In the first 10 sampling days there was no influence of the river
and on the 11th day of the Negro river waters begin to flood. A total of 14 taxons of copepods
were recorded, (Oithona amazonica, Macrocyclops albidus albidus, Mesocyclops brasilianus,
Metacyclops brauni, Thermocyclops sp., Aspinus acicularis, Rhacodiaptomus retroflexus,
Rhacodiaptomus calatus, Rhacodiaptomus calamensis, Dasydiaptomus coronatus,
Dactylodiaptomus pearsei, Notodiaptomus inflatus, Notodiaptomus coniferoides, Diaptomus
linus). Diaptomidae was the most representative with 9 species, followed by Cyclopidae who
presented four species and Oithonidae with only one representative. The specie Oithona
amazonica was the most abundant throughout the study, with ist maximum abundance
occurring in the lake's isolation period. The most abundant specie of Calanoida was Aspinus
acicularis which also showed higher abundance in the lake's isolation period. The entrance of
the Negro river waters negatively influenced the abundance of adult copepods and there was
also a decrease in nauplii and copepodites density. However, the diversity and species
richness increased during the rising water period. |
