This study investigated the impact of optically active substances on light attenuation in a tropical eutrophic urban reservoir under different seasonal conditions. Diffuse coefficients for photosynthetically radiation (KdPAR) and ultraviolet (KdUVA KdUVB) were measured at three representative sites correlated with water quality parameters (chlorophyll-a, total suspended solids [TSS], dissolved organic carbon, colored matter [CDOM]). The results revealed significant spatial differences,...
In this study, we examined the relationships between water quality, land use, and optical properties of dissolved organic matter (DOM) in Doce River Basin Southeast Brazil. By highlighting profound impacts human activities, such as agriculture, mining, urbanization, aim to provide a comprehensive assessment quality. We utilized DOM recognize inadequacy traditional indicators chlorophyll-a, especially turbid waters. collected samples from 27 sites along its tributary, Santo Antônio River,...
Abstract: Aims We assessed the beta diversity of macroinvertebrates associated with aquatic macrophytes in a dam-regulated river floodplain. tested two hypotheses: (1) have higher (higher turnover and nestedness components) downstream areas closer to São Francisco River compared upstream sites; (2) lakes share similarity macroinvertebrates, disregarding their position relative dam. Methods sampled four lakes, including (L1- natural L2- regulated by Small Hydropower Dam - SHD) (L3, L4,...
AbstractConventional methods that prioritize primary productivity as an indicator of water quality are widely used, but such may not capture the full scope anthropogenic impacts to which a river is subject. In this study, we sampled tropical river, measuring parameters and metrics related optical properties dissolved organic matter. We showed precipitation plays essential role in modulating inputs correlations inorganic substances water. The dominance protein-type DOM components emphasizes...
