Climbing the taxonomic ladder: Could a genus be used as bioindicator? The ecotoxicological relationship between biomarkers of Astyanax altiparanae, Astyanax bifasciatus and Astyanax ribeirae

Genotoxicity and cytotoxicity of textile production effluents in Astyanax lacustris (Pisces, Characidae), before and after treatment through the vertical flow constructed wetland system

“…Fish are important biological models for ecotoxicological studies (Bu, 2003) and specimens of Astyanax lacustris have shown sensitivity to the presence of a variety of chemical contaminants in polluted waters, often exposed to chemical or physical agents known as mutagens or carcinogens, which can induce modi cations in the DNA molecule (Tincani et al, 2019). Thus, the evaluation of biomarkers in sh can provide data on the environmental damage caused by toxic agents, such as textile e uents, helping to monitor aquatic environments.…”

Effects of heat shock on energy metabolism and antioxidant defence in a tropical fish speciesPsalidodon bifasciatus

“…Furthermore, it is the most dominant group in some watersheds and in the Iguaçu River due to its reproductive potential and trophic opportunism (Bueno‐Krawczyk et al ., 2015). Therefore, this species is a bioindicator of environmental alterations and has been used widely as a model in ecotoxicological studies (Bueno‐Krawczyk et al ., 2015; Nimet et al ., 2017; Nimet et al ., 2019; Tincani et al ., 2019). Thus, the aim of this study was to investigate changes in the activity of biomarkers associated with energy metabolism and antioxidant defence in the gills, liver and kidneys of P. bifasciatus in response to heat shock for 2, 6, 12, 24 and 48 h.…”

Ajustes fisiológicos de Astyanax altiparanae (Teleostei: Characiformes: Characidae) expostos a fármacos de preocupação emergente

“…Os peixes são organismos ideais para estudos ecotoxicológicos, pois podem estar em posição intermediária da cadeia alimentar, podendo ser um indicador indireto de toxicidade para outras espécies (Gómes-Martínez, 2011). O gênero Astyanax vem sendo amplamente utilizado como modelo para estudos ecotoxicológicos na América Latina(Tincani et al, 2019), devido à sua presença em diferentes ambientes e tamanho pequeno, o que permite fácil manuseio em aquários e gerenciamento laboratorial. Com base no exposto, o objetivo do presente estudo foi avaliar as respostas neurotóxicas, antioxidantes e genotóxicas de machos de Astyanax altiparanae frente à exposição subcrônica, a concentrações ambientalmente relevantes de DCF e CAF, combinados ou separados.…”
