“…This is because they tend to be generalists in their habitat choice inhabiting different environments regardless of the level of degradation [ 44 ]. This contrasts with a study by Mezgebu et al [ 45 ] in Ethiopia who found varying abundances of Diptera species across different pollution levels.…”

“…The results from CCA showed that taxa such as Hydrophilidae and Tipulidae were associated with low organic loads as has been demonstrated in other studies [ 22 , 45 ]. Diptera (e.g., Syrphidae and Chironomidae) were negatively correlated with DO and positively correlated with nitrates and phosphates.…”

“…Noninsect taxa in the study area, especially Oligochaeta, Atyidae, and Cladocera, responded more strongly to organic pollution as has been observed in other studies [ 45 ]. This is in agreement with most other studies where most noninsect taxa increase at degraded sites [ 51 ].…”

Biological monitoring of reservoirs is important in assessing aquatic health. This study aimed at assessing the structure of benthic macroinvertebrate communities in relation to physicochemical parameters along Sanyati basin shoreline in Lake Kariba, Zimbabwe. Six sites (S1 to S6) characterized by various human disturbances were sampled for physicochemical parameters and benthic macroinvertebrates from January to March 2018. We computed macroinvertebrate metrics and classified them into functional feeding groups (FFGs). A canonical correspondence analysis (CCA) triplot was constructed to assess species-physicochemical relations. Significant differences across the sampling sites were observed for pH, electrical conductivity, turbidity, nitrate-nitrogen (NO3-N), ammonium nitrogen (NH4-N), total nitrogen (TN), phosphate-phosphorus (PO4-P), total phosphates (TP), and dissolved oxygen (DO). The results from CCA highlighted that S1 was generally associated with high pH, NH4-N, and TN, and Oligochaeta, Syrphidae, and Hydrophilidae families. The highest percentage of EPT taxa (39.83%) was recorded at S6, while the lowest was recorded at S1. The taxa were made up of 50% predators, 26% collector-gatherers, 6% scrappers, 6% shredders, and 3% collector-filters with 3 taxa (Chironomidae, Hydropsychidae, and Leptoceridae) having more than two FFGs. Site S1 had a significantly higher mean abundance of collector-gatherers than the other sites. A high correlation between water parameters and SASS and ASPT scores was observed indicating their ability to detect environmental changes. These findings suggest that macroinvertebrate communities are good candidates for delineating the effects of industrial pollution on water quality.

“…Regarding population density, the Chironomidae larvae decreased from midstream to downstream along the river flow. Chironomid larvae have been reported as a bioindicator species in river habitats, but their tolerance varies across species and can range from heavily to lightly polluted sites [13]. According to this study, chironomids have a low tolerance to pollutants, hence, their population is higher on the upstream side of the river in the Purba District.…”

The community and composition of benthic macrofaunal species are determined in three sampling stations from upstream to downstream in Purba District. Sampling was performed in November 2021 during the rainy season. The results showed a population shift from upstream to downstream based on the predominance of insect and mollusk groups. The upstream was populated by Chironomus sp. (Insecta: Chironomidae) with 124 ind/m 2 , followed by Helicorbis sp. (Mollusca: Planorbidae) with 90 ind/m 2 , and Cambarincola sp. (Oligochaete) with 89 ind/m 2 . Helicorbis sp. with 298 ind/m 2 had the highest density in the midstream, followed by Cambarincola sp. (Oligochaete: Branchiobdllidae) with 285 ind/m 2 , and Melanoides sp. (Mollusca: Thiaridae) with 184 ind/m 2 . Furthermore, Melanoides sp. (533 ind/m 2 ), Helicorbis sp. (475 ind/m 2 ), and Limnodrilus sp. (288 ind/m 2 , Oligochaete: Naididae) were the three most dominant taxa in the downstream. The Shannon's diversity index (H') in upstream and downstream were both 2.12, while the downstream index was 1.90. There was a significant difference among stations based on relative taxa density (F 2,8 = 14.16, p = 0.005). Therefore, further research on other taxa groups, such as plankton and fish, should be conducted to increase the understanding of the anthropogenic effect on stream conditions in the Purba District.

“…As larvas possuem cabeça prognata (com aparelho bucal voltado para frete) e se locomovem por projeções (MUGNAI; NESSIMIAN; BAPTISTA, 2010), sendo comum a construção de casulos a partir do substrato e secreção salivar. As larvas se alimentam por meio de partículas (massa ovígera, algas, detritos como matéria orgânica e bactérias) que ficam aprisionadas dentro do casulo ou pela obtenção direta quando se impulsionam para fora dele (MEZGEBU et al, 2019;OLIVER, 1971;TRIVINHO-STRIXINO, 1980).…”
