“…D. pulex and D. magna also occurred widely in eutrophic waters. 63 , 64 D. pulex appears to tolerate to a more diverse cyanobacterial species than D. magna, confirmed by a culture comparison of feeding six different cyanobacteria genera. 65 Here, CYP genes, the important detoxification genes, were found to expand in both species of Daphnia , and evolved more members in D. pulex .…”

“…Increasing eutrophication causes a significant shift in the food composition of invertebrates and the structure of the food chain (van der Lee et al, 2021 ). Moreover, eutrophication changes the effects of pesticides and predators on target organisms (Oliveira dos Anjos et al, 2021 ). Consequently, trophic states will significantly change the density of water bugs or the species composition in a given water body.…”

As water pollution poses an increasing risk worldwide, it is timely to assess the achievements of the aquatic macroinvertebrate ecotoxicology to provide a sound basis for the discipline’s future and support the development of biomonitoring. Aquatic and semi-aquatic bugs (Hemiptera: Nepomorpha, Gerromorpha) are ubiquitous in almost all water types, sometimes in high densities, and play a significant role in organic material turnover and energy flow. Nevertheless, they are ignored in the water pollution biomonitoring schemes. Here, based on 300 papers, we review and evaluate the effects of chemical pesticides, microorganism-derived pesticides, insecticides of plant origin, heavy metals, eutrophication, salinisation and light pollution which are summarised for the first time. Our review encompasses the results of 100 laboratory and 39 semi-field/field experiments with 47 pesticides and 70 active ingredients. Pyrethroids were found to be more toxic than organochlorine, organophosphate and neonicotinoid insecticides to water bugs, like other macroinvertebrate groups. Additionally, in 10 out of 17 cases, the recommended field concentration of the pesticide was higher than the LC50 values, indicating potential hazards to water bugs. The recommended field concentrations of pesticides used in mosquito larvae control were found non-toxic to water bugs. As very few replicated studies are available, other findings on the effects of pesticides cannot be generalised. The microorganism-derived pesticide Bti appears to be safe when used at the recommended field concentration. Data indicates that plant-derived pesticides are safe with a high degree of certainty. We have identified three research areas where water bugs could be better involved in water biomonitoring. First, some Halobates spp. are excellent, and Gerris spp. are promising sentinels for Cd contamination. Second, Micronecta and, to a certain extent, Corixidae species composition is connected to and the indicator of eutrophication. Third, the species composition of the Corixidae is related to salinisation, and a preliminary method to quantify the relationship is already available. Our review highlights the potential of water bugs in water pollution monitoring.

“…For example, extreme weather events, such as droughts or heat waves, have been proposed as key factors influencing the pace of population recovery to chemical stress events (Arenas‐Sanchez et al, 2019; Polazzo, Roth, et al, 2022). dos Anjos et al (2021) showed that food availability, expressed as the biomass of primary producers in eutrophic and mesotrophic mesocosms, can affect the recovery capacity of D. magna exposed to pesticides. On the other hand, several studies have demonstrated that interspecific competition or the presence of efficient predators significantly delays recovery of microcrustacea and insect populations following pesticide exposure (Foit et al, 2012; Knillmann et al, 2012), while in some cases such interference can be obscured by other “less common” ecological interactions such as intraguild predation (Van den Brink et al, 2017).…”

“…In other words, this would allow us to assess the potential of the local community to recover without external subsidy. However, it should be considered that enclosures will inevitably induce experimental artifacts, such as clogging, which affects flow, or the limited ability of prey escaping from a predator (dos Anjos et al, 2021). Insects with a flying and thus terrestrial life stage represent an additional challenge because this life‐history trait will allow organisms to disperse independently of the stream network as such.…”

Recovery, recolonization, and adaptation in a chemical stress context are processes that regenerate local populations and communities as well as the functions these communities perform. Recolonization, either by species previously present or by new species able to occupy the niches left empty, refers to a metacommunity process with stressed ecosystems benefiting from the dispersal of organisms from other areas. A potential consequence of recolonization is a limited capacity of local populations to adapt to potentially repeating events of chemical stress exposure when their niches have been effectively occupied by the new colonizers or by new genetic lineages of the taxa previously present. Recovery, instead, is an internal process occurring within stressed ecosystems. More specifically, the impact of a stressor on a community benefits less sensitive individuals of a local population as well as less sensitive taxa within a community. Finally, adaptation refers to phenotypic and, sometimes, genetic changes at the individual and population levels, allowing the permanence of individuals of previously existing taxa without necessarily changing the community taxonomic composition (i.e., not replacing sensitive species). Because these processes are usually operating in parallel in nature, though at different degrees, it seems relevant to try to understand their relative importance for the regeneration of community structure and ecosystem functioning after chemical exposure. In the present critical perspective, we employed case studies supporting our understanding of the underlying processes with the hope to provide a theoretical framework to disentangle the relevance of the three processes for the regeneration of a biological community after chemical exposure. Finally, we provide some recommendations to experimentally compare their relative importance so that the net effects of these processes can be used to parameterize risk‐assessment models and inform ecosystem management.
