Resumo: | The characterization of hydrological basins and the development of environmental evaluation tools to subsidize the sustainable management of water resources require interdisciplinary approaches. The aim of this study was to integrate ecological and geographic metrics to evaluate water quality in the Velhas river basin, a tributary of the São Francisco river (Minas Gerais, Brazil). For that it was used data on the composition of benthic macroinvertebrate assemblages of 19 different tributaries in the Velhas river basin. Geographic information was acquired for each of the sampling site drainage sub-basins, consisting of urban and rural population density, sanitary infrastructure and land use and cover. These metrics were synthesized through a Principal Component Analysis (PCA) and the associations between ecological and geographical metrics were analysed using linear regressions, with the three most representative axes of PCA as predictors synthesizing: (i) urban influence (44.37%), (ii) rural influence (16.88%), and (iii) influence of natural coverage (14.63%). The models generated for the biological metrics Richness, diversity of Shannon-Wienner, BMWP, ASPT and % of Oligochaeta showed a significant correlation (R2 ≥ 44-90, p <0.002) and all were dependent on the first axis of the PCA, evidencing that the biological metrics are sensitive to urban pressures. We conclude that urbanization is the main cause of degraded water quality in the Velhas River hydrological basin, with potential to compromise it for the entire São Francisco River basin. |

O objetivo deste estudo foi integrar métricas ecológicas e geográficas para diagnosticar qualidade de água na bacia do rio das Velhas, afluente do rio São Francisco (Minas Gerais, Brasil). Foram utilizadas as características da composição e estrutura de comunidades de bioindicadores bentônicos coletados em 19 diferentes afluentes na bacia do rio das Velhas. As informações geográficas foram adquiridas para cada uma das sub-bacias de drenagem de sítio amostral. A densidade populacional urbana e rural, a infraestrutura sanitária e o uso e cobertura da terra foram sintetizados através de uma análise de componentes principais (PCA). As associações entre as métricas ecológicas e geográficas foram analisadas através de regressões lineares, utilizando os três eixos mais representativos da PCA como preditores, sintetizando: (i) influência urbana (44,37 %), (ii) influência rural (16,88 %) e (iii) influência da cobertura natural (14,63 %). Os modelos gerados para as métricas biológicas riqueza taxonômica, diversidade de Shannon-Wienner, BMWP, ASPT e % Oligochaeta foram significativos (R2 ≥ 44-90, p < 0,002) e todos foram dependentes do primeiro eixo da PCA, evidenciando que as métricas biológicas são sensíveis às pressões urbanas. Nós concluímos que a urbanização é a principal fonte de influência de degradação de qualidade das águas do rio das Velhas, com potencial comprometimento para a bacia do Rio São Francisco.UFVJM2019-06-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArtigo avaliado pelos Paresapplication/pdfhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/13110.5281/zenodo.3345811Revista Espinhaço ; Revista Espinhaço #142317-0611reponame:Revista Espinhaçoinstname:Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)instacron:UFVJMporhttps://revistas.ufvjm.edu.br/revista-espinhaco/article/view/131/142Copyright (c) 2022 Revista Espinhaço https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessCallisto, MarcosMoreno, PabloMacedo, Diego Rodrigues2022-07-22T18:47:37Zoai:ojs.pkp.sfu.ca:article/131Revistahttps://revistaespinhaco.com/index.php/revista/indexPUBhttps://revistas.ufvjm.edu.br/revista-espinhaco/oairevista.espinhaco@gmail.com || doug.sathler@gmail.com2317-06112317-0611opendoar:2022-07-22T18:47:37Revista Espinhaço - Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM)false |
