“…Second, in comparison to low G. pulex abundance and effective population size found at upstream sites H1 and H2, high abundances in the polluted river sections and large effective population sizes directly after WWTPs can be maintained due to abundant food supply (fungi and biofilms) resulting from the input of anthropogenic nitrate and organic carbon, which enter the river through WWTP effluents and agricultural field drainage. , Additionally, the number of private alleles does not show any dramatic increase downstream of the WWTPs in our study. Thus, slightly increased allelic richness values downstream of WWTPs are probably due to a larger allele pool in lower reaches because of migration to the river.…”

“…We performed a study at the Holtemme River, serving as a landscape model for studies of the effects of anthropogenic pollution on riverine ecosystem functioning. ,− We analyzed the widespread Palearctic amphipod species G. pulex, which occurs in rivers with different degrees of pollution. − It is common in the Holtemme River, where two distinct populations were described in the past .…”

Anthropogenic micropollutants alter chemical and ecological conditions of freshwater ecosystems and impact aquatic species that live along the pollution gradient of a river. Species sensitivity to micropollutants depends on the site-specific exposure; however, it remains unclear to what degree this sensitivity relates to the species’ genetic structure. Here, we explored the relationship between the toxic sensitivity and genetic structure of the amphipod species Gammarus pulex (Linnaeus, 1758) along an organic micropollutant gradient in the Holtemme River in central Germany. We determined the river’s site-specific micropollutant patterns and analyzed the genetic structure of G. pulex using nuclear and mitochondrial genetic markers. Furthermore, we examined the exposure sensitivities and bioaccumulation of the commonly detected insecticide imidacloprid in G. pulex from different sites. Our results show that throughout the Holtemme River, G. pulex forms a well-connected and homogeneous population with no observable pollution-related differences in the genetic structure. However, G. pulex from polluted sites responded more sensitively to imidacloprid; survival times for half of the amphipods were up to 54% shorter, the percentage of immobile individuals increased up to 65%, and the modeled imidacloprid depuration rate was lower in comparison to amphipods from non-polluted sites. Altogether, these results suggest that the level of sensitivity of G. pulex amphipods to micropollutants in the river depends on the degree of pollution: amphipods may thrive in food-rich but polluted habitats; yet, their sensitivity is increased when chronically exposed to organic micropollutants.

“…Chronic tests are particularly important for environmental monitoring and species protection and conservation because risks to biota can be detected when sublethal effects are considered (Silva & Abessa, 2019). Biological effects of pollutants from wastewater emissions have been reported to cause biochemical and physiological perturbations under sublethal exposure conditions (Karrasch et al, 2019;Wigh et al, 2017).…”

and microbiological parameters were measured and integrated using the Water Quality Index of the Canadian Council of Ministers of the Environment. Ecotoxicological tests were performed with Brazilian endemic organisms to assess the impact of water pollution on biota. A generalized linear regression model was applied to understand the effects of water quality on ecotoxicological responses. Concentrations of metals, dissolved oxygen, total ammonia nitrogen, nitrate, and thermotolerant coliforms did not comply with Brazilian environmental regulations. A significant increase in the mortality rate of Mysidopsis juniae and Nitocra sp. and a significant decrease in the reproductive rate of Nitocra sp. indicated the most affected areas related to the discharge of treated and untreated wastewater. Only 10% of the samples from sites without direct wastewater impact showed a toxic response in at least one organism. Both water quality and sampling sites were statistical predictors of ecotoxicological response, describing not only the pollutant load but also the type of effluent. This study demonstrated the degradation of the environmental quality of the JPE, particularly due to the discharge of sanitary wastewater, and highlights the importance of protection and remediation measures to preserve this protected area.
