Resumo: | Urbanization causes many changes in stream communities and rivers usually suffer major structural modifications under intense urban occupation. The goal of this study was to investigate the effects of urbanization on physicochemical habitat characteristics and evaluate the responses of urbanization on functional feeding groups (FFGs) of invertebrates. Water quality parameters (temperature, conductivity, dissolved oxygen, pH, phosphorus, chlorophyll-a, turbidity and organic matter) and flow parameters were measured in least and severely urbanized areas. FFGs of macroinvertebrates were analyzed and applied as surrogates of ecosystem attributes. The differences in the macroinvertebrate community of the least and severely urbanized areas were assessed using non-metric multidimensional scaling (nMDS) and a permutational multivariate analysis of variance (Permanova). Differences between the least and severely urbanized areas were observed with nMDS. The Permanova also showed a significant difference between the nMDS groups. The least urbanized areas presented greater richness for each FFG. On the other hand, severely urbanized areas presented a major abundance of gathering collectors and predators. Thus, the composition of FFGs responded to habitat alterations that were represented by water quality and the flow parameters. |

Sob ocupação urbana intensa, os rios sofrem as maiores modificações estruturais. O objetivo do trabalho foi avaliar os efeitos da urbanização nas características físicas e químicas do habitat e as respostas da urbanização nos grupos funcionais de alimentação (FFG) dos invertebrados. Parâmetros de qualidade da água (temperatura, condutividade, oxigênio dissolvido, pH, fósforo, clorofila-a, turbidez e matéria orgânica) e parâmetros do escoamento foram medidos em áreas pouco e altamente urbanizadas. Os FFG dos macroinvertebrados foram analisados e aplicados como substitutos de atributos do ecossistema. As diferenças na comunidade dos macroinvertebrados entre as áreas pouco e altamente urbanizadas foram avaliadas pelo escalonamento multidimensional não-métrico (nMDS) e pela análise de variância permutacional multivariada (Permanova). No nMDS foram observadas diferenças entre as áreas pouco e altamente urbanizadas. A Permanova mostrou diferença significativa entre os grupos do nMDS. As áreas pouco urbanizadas apresentaram maior riqueza em cada FFG, por outro lado, as áreas altamente urbanizadas apresentaram maiores valores de abundância de organismos coletores e predadores. Assim, a composição dos FFG respondeu às alterações no habitat que foram representadas pelos parâmetros de qualidade da água e do escoamento.Universidade Federal de Santa Catarina2019-12-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2019v32n4p2910.5007/2175-7925.2019v32n4p29Biotemas; v. 32 n. 4 (2019); 29-442175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCenghttps://periodicos.ufsc.br/index.php/biotemas/article/view/2175-7925.2019v32n4p29/42049Copyright (c) 2019 Jucimara Andreza Rigotti, Cesar Augusto Pompêo, Alessandra Larissa d'Oliveira Fonsecainfo:eu-repo/semantics/openAccessRigotti, Jucimara AndrezaPompêo, Cesar AugustoFonseca, Alessandra Larissa d'Oliveira2019-12-12T07:56:23Zoai:periodicos.ufsc.br:article/63078Revistahttp://www.biotemas.ufsc.br/index.htmPUBhttps://periodicos.ufsc.br/index.php/biotemas/oai||carlospinto@ccb.ufsc.br2175-79250103-1643opendoar:2019-12-12T07:56:23Biotemas (Online) - Universidade Federal de Santa Catarina (UFSC)false |
