“…The level of pH also had a considerable effect on mayfly assemblages. This water parameter regulates important physiological functions of mayflies, including the exchange of ions with the water and respiration (Kubendran, Selvakumar, Sidhu, Nair, & Krishnan, 2017;Svitok, 2006;Vilenica, Ivković, et al, 2017) which otherwise is impossible to operate normally under extreme pH values (>8.5 and <6.5) (Klonowska-Olejnik & Skalski, 2014). In this study, water tends to get more acidic at higher elevation sites because of less anthropogenic impacts that include sewage discharge, car washing, body and clothes washing, animal grazing, and subsistence farming which contribute to the rising level of pH (Okonkwo & Mothiba, 2005).…”

Freshwater organisms are threatened by changes in stream flow and water temperature regimes due to global climate change and anthropogenic activities. Threats include the disappearance of narrow‐tolerance species and loss of favorable thermal conditions for cold‐adapted organisms. Mayflies are an abundant and diverse indicator of river health that performs important functional roles. The relative importance of key hydro‐environmental factors such as water temperature and flow volumes in structuring these communities has rarely been explored in the tropical regions of Africa. Here, we investigate the response of mayfly species diversity to these factors in the Luvuvhu catchment, a strategic water source area in the arid northeastern region of South Africa. Mayfly larvae were sampled monthly in stones‐in‐current biotopes across 23 sites over a one‐year period. The relationship between these environmental drivers and mayfly diversity was modeled using linear mixed effects models (LMMs) and a model‐based multivariate approach. Threshold Indicator Taxa Analysis (TITAN) was used to model the response of mayfly species to important gradients and identify thresholds of change. Site‐specific characteristic were the most important predictor of mayfly diversity, and there was considerable variation over time, with mayfly diversity peaking during winter. Along this, gradient temperature was the best predictor of assemblage structure, with five out of six reliable indicator species being cold‐adapted, and a community threshold response at 19°C. Results support laboratory‐based thresholds of temperature for mayfly species survival and development, extending empirical evidence to include field‐based observations. Increased global (climate change) and local (riparian vegetation removal, impoundments) changes are predicted to have negative impacts on mayfly diversity and ultimately on ecosystem function.

In this article, aquatic mayflies from several wadis in Jordan are studied on their potential use as environmental indicators. Nine species of mayfly were observed in the studied wadis, encompassing Baetis monnerati, Cheleocloeon soldani, Cloeon vanharteni, Cloeon gr simile, Baetis pacis, Nigrobaetis vuatazi, Choroterpes ortali, Caenis antoniae, and Caenis macrura. Among Baetidae species, Baetis monnerati was more abundant and seems to be the most tolerant species to pollution. In addition, it tolerates water salinities of up to reach 1.000 µS/cm. Contrastingly, Baetis pacis was also observed to be the most intolerant species to pollution. The species survives in very good freshwater quality that makes it a perfect indicator of very clean water. Cloeon vanharteni live in brackish lentic habitat with dense vegetation. This species was found together with Cloeon gr simile. Both can tolerate salty water, with salinities of up to 16.000 µS/cm and tolerate in addition, organically polluted water. Furthermore, Choroterpes ortali was found to colonize slightly saline, mineralized and polluted water like Nigrobaetis vuatazi and Cheleocloeon soldani.Caenis macrura indicates clean to moderate polluted while Caenis antoniae is less pollution-tolerant, and only found in clean to weakly polluted environments. The study concludes that Baetidae mayflies can serve as powerful indicators of the environmental conditions than other mayfly families in Jordan.

“…As expected, in the present study macroinvertebrate assemblages at UNR showed a higher abundance and richness of taxa sensitive to organic contamination such as Trichoptera (Glossosomatidae and Hydropsychidae) and Ephemeroptera (Leptophlebiidae, Baetidae and Caenidae) than at DNR. These groups are widely accepted as bioindicators of good water quality (Brasil et al 2014;Kubendran et al 2017;Thamsenanupap et al 2021) and are highly sensitive to agricultural pollution, including nutrients and pesticides (Schulz et al 2002;Beketov 2004;Thiere and Schulz 2004;Beuter et al 2019;Vilenica et al 2020;Rojas-Peña et al 2021).…”
