“…Among the taxa that were negatively correlated with the pollution levels in the sediments and water column, many belong to Ephemeroptera and Hemiptera. Several studies have demonstrated that many Ephemeroptera species are sensitive to organic pollution 30,31 and metals 32 . Therefore, total nitrogen, total phosphorus and metals may result in the negative responses of Ephemeroptera species in our study.…”

Constructed stormwater ponds mitigate runoff volumes and pollution, and provide other ecosystem services, such as supporting biodiversity, but these services attracted relatively less attention. The impacts of the pollution levels in the water column and sediments, the physical characteristics of ponds, and the presence of amphibians on the macroinvertebrate community composition and biodiversity were explored in twelve stormwater ponds in Norway. Also, the similarities between macroinvertebrate, zooplankton and plant communities were explored. Most of the taxa displayed in the ordination diagram were positively correlated with the pond size and the number of neighbouring ponds, and negatively correlated with the pollution levels in the water column and sediments. However, no statistically significant impacts on the number of taxa and Shannon index were observed. There were low similarities between the macroinvertebrate and zooplankton community compositions as well as between the plant and macroinvertebrate community compositions in the stormwater ponds. We observed a significant positive correlation between the number of plant and of zooplankton taxa, and a weak non-significant positive correlation between the number of plant and of macroinvertebrate taxa. Overall, the explanatory variables had a significant impact on the community composition, but not on the number of taxa nor Shannon index.

“…EPT‐related indices were shown by numerous studies to perform well in distinguishing river ecosystems, due to the sensitivity in richness and abundance of Ephemeroptera, Plecoptera and Tricoptera to the environmental changes (e.g., Bispo et al., 2006; DeWalt & South, 2015; Judson & Nelson, 2010; Kerans et al., 1992). In general, river ecosystems are considered better when there is higher richness or abundance of EPT taxa (Chun et al., 2017). Indices relating to the tolerance of macroinvertebrates, generally considered as metrics to detect organic pollution (e.g., Kerans & Karr, 1994; Li et al., 2010; Masese et al., 2009), also responded well to the hydrodynamic and substrate variations in this study.…”

The Qinghai-Tibet Plateau (QTP), also known as the Third Pole Region, is the largest high-altitude land mass on Earth. The region holds the most freshwater, mainly in the form of glaciers, outside the polar ice caps (Morton, 2011). The QTP is of critical ecological importance, possessing diverse biomes (alpine tundra, montane forest, subtropical dry forest, and tropical montane rainforest; Ni & Herzschuh, 2011), and encompasses several biodiversity hotspots (e.g., in the mountainous areas of Central Asia, Himalayas, Indo-Burma, and Hengduan range; Tang et al., 2006). The river and stream biota in the QTP are highly specialized owing to the unique conditions, making them especially vulnerable to external disturbances (Favre et al., 2015;Xu et al., 2018;Yao et al., 2012). Environmental conditions that have been intensively modified by anthropogenic activities and climate warming during recent decades include instream flows, jeopardizing the services provided by alpine rivers with healthy ecosystems (Poff et al., 1997;Wenger et al., 2011).

“…Therefore, EPT is often used as a bioindicator to study the habitat and water quality of aquatic ecosystems (Rosenberg & Resh 1993). The presence of EPT indicates a habitat has not been heavily polluted (Chun et al 2017). These groups of insects prefer clear, unpolluted fast flowing streams and are sensitive to water pollution (Subramanian & Sivaramakrishnan 2007a).…”

“…Aquatic insects can be used as an indicator of the quality of a water. Ephemeroptera, Plecoptera, and Trichoptera (EPT) are often found in clean waters and very sensitive to changes in water physics and chemistry (Chun et al 2017). Apart from the metal content in water, several other environmental factors such as temperature, pH, dissolved oxygen, electrical conductivity, turbidity, sulfate, nitrate -nitrogen, orthophosphate, ammonia-nitrogen, and alkalinity in water also influence the presence of aquatic insects (Prommi et al 2014).…”

The diversity of aquatic insects surrounding the gold mining areas of central sulawesi and their relation with mercury levels and water quality

et al. 2022

Human activities may influence the diversity of aquatic insects in rivers. This study aims to assess the diversity of aquatic insects and their relation with mercury levels and water quality along rivers located near the gold mine in Poboya, Central Sulawesi. The insects were collected at six locations based on human activity levels. At each site, the mercury level of water was measured using atomic absorption spectrophotometry (AAS). In addition, water temperature, acidity, dissolved oxygen, and total dissolved solids were determined. The study recorded 23 species of aquatic insects belonging to 7 orders and 14 families. Mercury levels in the rivers did not exceed the threshold except at two sites and did not affect aquatic insects’ diversity. The diversity of aquatic insects, however, tends to decrease downstream. The diversity of aquatic insects, particularly the Ephemeroptera, Plecoptera, and Trichoptera orders, tended to be higher at the higher dissolved oxygen sites.
