Resumo: | The evaluation of the primary productivity in lotic environments has great relevance, since it allows to know the metabolism of aquatic system, as well as the entrance of energy and the influences in the cycles of carbon and other variables. In the water bodies, the abiotic conditions have undergone alterations due to the anthropic interferences, causing impacts in aquatic communities. The study was carried in Córrego Lanoso, in city of Uberaba/MG. With the objective of evaluating the primary productivity of a lotic environment and analyzing the influence of water quality parameters, sampling was performed to determine the primary productivity. This was done in two distinct points of Lanoso Stream; the methodology used was method of light and dark bottles by means of the technique of Winkler, modified by Pomeroy and Kirschmann, 1945. The physical-chemical parameters (temperature, turbidity and pH) were obtained in situ via probe. The results showed that the primary productivity was higher at the point near nascent, when compared to the downstream. Regarding the physical-chemical parameters, only turbidity obtained a significant variation, being this limiting factor for the primary productivity, since greater turbidity less absorption of light and hence less phytoplanktonic activity of ecosystem. |

Nos corpos hídricos, as condições abióticas têm sofrido alterações em decorrência das interferências antrópicas, acarretando impactos nas comunidades aquáticas. O estudo foi realizado no Córrego Lanoso, Município de Uberaba/MG. Com o objetivo de avaliar a produtividade primária de um ambiente lótico e analisar a influência de parâmetros de qualidade da água foi realizada amostragem para a determinação da produtividade primária. Esta ocorreu em dois pontos distintos do Córrego Lanoso e a metodologia utilizada foi o Método de frascos claros e escuros por meio da técnica de Winkler, modificado por Pomeroy e Kirschmann, 1945. Os parâmetros físico-químicos (temperatura, turbidez e pH) foram obtidos in situ, através de sonda. Os resultados mostraram que a produtividade primária foi maior no ponto próximo a nascente, quando comparado ao ponto jusante. Com relação aos parâmetros físico-químicos, apenas a turbidez obteve variação significativa, sendo este o fator limitante para a produtividade primária, já que quanto maior a turbidez menor absorção da luz e consequentemente menor atividade fitoplanctônica do ecossistema.Editora Uningá2019-06-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revista.uninga.br/uningareviews/article/view/2951Uningá Review ; Vol. 34 No. 2 (2019): Revista UNINGÁ Review; 16-27Uningá Review Journal; v. 34 n. 2 (2019): Revista UNINGÁ Review; 16-272178-2571reponame:UNINGÁ Reviewinstname:Centro Universitário Uningáinstacron:UNINGAporhttps://revista.uninga.br/uningareviews/article/view/2951/2152Copyright (c) 2019 REVISTA UNINGÁ REVIEWinfo:eu-repo/semantics/openAccessSILVA, PEDRO DE SOUZA LOPESRODRIGUES, VINICIUS SILVATERRA, FERNANDA REZENDEOLIVEIRA, CAROLINE FÁVAROLAET, HELEN SANDRA DE SOUSAPELLI, AFONSO2019-12-03T16:37:52Zoai:ojs.revista.uninga.br:article/2951Revistahttps://revista.uninga.br/uningareviews/indexPUBhttps://revista.uninga.br/uningareviews/oairevistauningareview@uninga.edu.br || sec.revistas@uninga.edu.br2178-25712178-2571opendoar:2019-12-03T16:37:52UNINGÁ Review - Centro Universitário Uningáfalse |
