“…Chironomidae were the most abundant family during summer, whereas in winter Chironomidae were not identified. These results are similar the findings of Odume and Muller (2011) and Dalu et al (2017b) who observed increased Chironomidae diversity during the summer season. Chironomidae taxa are tolerant to water pollution.…”

The Vhembe Biosphere Reserve, South Africa, contains many wetlands that serve as wildlife habitats and provide vital ecosystem services. Some of the wetlands are continuously being degraded or destroyed by anthropogenic activities causing them to disappear at an alarming rate. Benthic macroinvertebrates are known as good water quality bioindicators and are used to assess aquatic ecosystem health. The current study investigated habitat quality using macroinvertebrate community structure and other biotic variables (i.e. phytoplankton, macrophytes) in relation to environmental variables in the Sambandou wetlands using canonical correspondence analysis (CCA). A total of fifteen macroinvertebrate families were identified over two seasons. The CCA highlighted seven variables, i.e. pH, phosphate concentration, temperature, ammonium, macrophyte cover, conductivity and water depth, which were significant in structuring macroinvertebrate community. Picophytoplankton and microphytoplankton concentrations decreased from winter to summer, whereas nanophytoplankton concentration increased from winter to summer. Thus, the dominance of small-sized phytoplankton indicated nutrient limitation and decreased productivity, whereas winter sites 2 and 3 were dominated by large-celled phytoplankton, highlighting increased productivity. Winter sites were mostly negatively associated with CCA axis 1 and were characterised by high temperature, phosphate and ammonium concentrations, macrophyte cover, pH and conductivity. Summer sites were positively associated with axis 1, being characterised by high water depth and pH levels. The results obtained highlighted that agricultural activities such as cattle grazing and crop farming and sand mining/poaching had a negative effect on macroinvertebrate community structure.

“…This hinders the possibility of an effective estimation of biodiversity. More valuable results are otherwise observed when chironomid species identification is undertaken (Marziali et al, 2010;Chaib et al, 2011;Odume and Muller, 2011;Milošević et al, 2012). Species identification is quite important for the Mediterranean area -Southern Mediterranean, in particular -an area where many species are at serious risk of extinction, because of the increasing pressure on water as a resource, with the situation being aggravated by climate warming and other global changes (Hulme et al, 2001); there is the serious risk that autochthonous and endemic species disappear, with a concomitant increase of opportunistic species.…”

“…Chironomous sp merupakan sejenis serangga yang tergolong famili Chironomidae (Shafruddin, dkk, 2006), memiliki habitat di perairan yang kaya bahan organik (Arimoro, et al, 2007). Famili Chironomidae menjadi 10-15% biomassa makroinvebrata air yang masing-masing subfamily maupun ordonya memiliki preferensi tertentu terhadap kondisi suatu lingkungan perairan (Odume & Muller, 2011;Fardhani dkk, 2014), merespon cepat perubahan kondisi perairan (Heinrich et al, 2006), sehingga dapat digunakan untuk indikator pencemaran.…”

Wastewater is a residual from detergents usage that has negative impact to the environment, such as aquatic biota toxid. The Model of aquatic biota mortality as a function of detention time for the wastewater detergent concentration was eliminated by secondary data. Model is selected by election of trendline type that have highest determination coefficient, while simple idea of the detergent pollution control technique was analized from previous research and some other aspect. Result showed that aquatic biota mortality with perception time can be expressed with second order polynominal model. Damage of the vital aquatic biota organ such as cell membran, liver and heart, and also water quality degradation is allegedly caused of organisms mortality as a due to detergent increased in water bodies. A very high detergent concentration, is endangering biota in water bodies. Usage of environmentally friendy detergens, and also wastewater treatment for detergent before entering the water bodies, is expected to protecting more aquatic biota so that ecosystem can maintained. Individual detergent screening technique (TPDI) idea expected acceptable and exploted by public as one of the detergent pollution control.
