“…Goncharov et al [10] indicates that using the density index of Ephemeroptera Plecoptera-Trichoptera (EPT); showed a capacity for regeneration of these indicator groups under unfavorable conditions. Cortelezzia [3] indicates that In some taxa of chironomids, their potential as a bioindicator increased as the taxonomic level decreased (eg, Chironominae).…”

The wetland of Naâma situated in the arid region of Alegria offers an important fauna and flora diversity due to its geographical location it constitutes the main resting place in North Africa for migratory birds. Insects are used as bioindicators, due to their sensitivity to environmental conditions which, because of their ecological peculiarities, gives information on the characteristics of terrestrial and aquatic environments. The aim of this study is to know and specify the entomofauna bio-indicator of the quality of the aquatic environment of the wetland Naâma (SW Algeria). The study carried out in the wetland from September 2017 to September 2020. Benthic insects were sampled according to the IBGN protocol (Standard Global Biological Index). Study and statistical analysis of insects communities was based by the use of the structural and statistical index, Correspondence factor analysis (CFA), and The ascending hierarchical classification (C.H.A). The results show that the collected insect 51 species, belong to 9 orders, The Coleoptera order is the most represented with 11 species, followed by the Odonata with six species, Lepidoptera ranks third with five species followed by Diptera with 03 species. The various indicators used, namely the specific richness (51 species), the Shannon index (1.01 bits), and fairness (0.56) show that this environment is characterized by significant fauna biodiversity. The study of the hydro-biological quality of the water courses of this site, assessed by the IBGN method showed a good hydro-biological quality with moderate pollution (IBGN = 14). This pollution is precisely marked by the requirement of Ephemeroptera and the disappearance of Plecoptera. These results lay the foundation for any biomonitoring action of the ecological quality of the waters of this wetland.

“…Os coleópteros da família Elmidae são encontrados nos mais diversos ambientes aquáticos, desde ambientes de águas muito limpas e bem oxigenadas, até locais considerados moderadamente impactados, o que torna sua presença possível em corpos d'água com diferentes características ambientais (DOMÍNGUEZ et al, 1998;SANTOS et al, 2011;SEGURA et al, 2012;GONZÁLEZ-CÓRDOBA et al, 2020). As ninfas da família Caenidae são distribuídas em grande número nos ambientes aquáticos, sendo consideradas generalistas e bastante tolerantes a ambientes poluídos (ALBA-TERCEDOR, 1996;SILVA, 1998;DOMÍNGUEZ et al, 2006;SALLES, 2006;LOPES et al, 2008) e ocorrem em grande abundância em diversos levantamentos realizados recentemente com biomonitoramento (LAINI et al, 2019;MUSONGE et al, 2019;SMITH et al, 2019;GONCHAROV, 2020).…”

A fauna de insetos aquáticos é um componente fundamental para o funcionamento dos recursos hídricos. No presente estudo foi realizado o levantamento da fauna de insetos aquáticos em doze propriedades com produção de leite localizadas na microbacia hidrográfica do Arroio da Seca, porção Taquari-Antas, em relação à estrutura da comunidade associada ao estado de conservação da vegetação nativa das Áreas de Preservação Permanente (APP). As amostragens foram realizadas de fevereiro a novembro de 2019 ao longo das margens d’água de arroios de cada propriedade leiteira no Vale do Taquari, nos municípios de Colinas e Imigrante. Foram coletados e identificados um total de 2.724 indivíduos de insetos aquáticos, pertencentes a 8 ordens e 38 famílias. Não houve diferença significativa entre a riqueza e a abundância de insetos aquáticos entre os pontos de coleta, porém a composição de famílias entre os diferentes locais amostrados indicou diferença. Entre as três categorias de conservação a composição de famílias foi significativamente diferente. Conclui-se que a entomofauna aquática presente nos ambientes lóticos das propriedades leiteiras amostradas sofreram alterações na distribuição de famílias nos diferentes percentuais de conservação de suas APP nativas.

“…However, it is still a particularly dangerous object, on the territory of which poisonous waste is stored near the coast, a heating plant operates, and nearby there is the Gusinoozerskaya GRES, the Selenginsky pulp and cardboard mill, various production facilities of Irkutsk. Ulan-Ude dumps 200 thousand cubic meters of industrial waste into the Selenga per day, and the eggs of fish that go to spawn at the mouth of the river almost completely die from poisoning [6].…”

Requiem for Baikal as a warning

Baikal, the “sacred sea”, a unique natural phenomenon with fresh water resources for the entire planet, is threatened with turning into a muddy puddle. In recent years, the shores of Lake Baikal have become more and more accessible for exploration by tourists from the center of Russia and abroad. Tourists and entrepreneurs from China, who compensate for the economic vacuum in Siberia, providing the local population with work in the absence of a state system of economic integration of the region into the general economic structure of the country, are especially actively populating the south of Baikal. Travel companies that have reached Lake Baikal provide guests with minimal comfort in primitive coastal houses and do not care about neutralizing household waste flowing into the lake. The most dangerous source of pollution is the pools with poisonous sludge located on the very shore of the lake, which were left after the closure of the Baikal Pulp and Paper Mill in 2013. In the near future they can be washed away by mountain mudflows. It is necessary that the central and local authorities, when creating the programs to prevent the destruction of Lake Baikal, should be guided by the simplest form of survival developed by nature to extinguish the phenomena that threaten its existence. This is the concept of METABOLISM, which means a system of living in the regime of the circulation of substances, the real preservation of the ecological balance even by tough measures of educating the consciousness of a person.
