“…Different responses from species from the same thermal niche have also been detected at the sub-cellular level, even in congeneric species. Vinagre et al (2014) found that Palaemon elegans and Palaemon serratus, two shrimp species that occur in intertidal pools, present different oxidative stress response patterns when subjected to the CTMax experiment. Since both species occupy the same thermal niche, and were acclimated to the same temperature, the authors concluded that although congeneric, these species may have different evolutionary histories influencing their sub-cellular response to thermal stress.…”

“…Studies have indeed shown the complexity of incorporating thermal history into measurement of the cellular stress and heat shock response, i.e., responses to longer term ""chronic"" vs. shorter term ""acute"" thermal stresses (Helmuth and Hofmann, 2001). This emphasizes the importance of knowing the species-specific response to natural seasonality in environmental variables when selecting species and sampling periods for bio-monitoring (Vinagre et al, 2014).…”

“…Nevertheless, there are several reports concerning patterns of CAT expression under oxidative-stress-inducing conditions, such as chemical toxicity and thermal stress. These antioxidant defenses may be increased (Khessiba et al, 2005;Vinagre et al, 2012Vinagre et al, , 2014, inhibited (Kaur et al, 2011;Sabatini et al, 2011) or unaffected (Mueller et al, 2012;Gabriel et al, 2013;Machado et al, 2014) by agent stressors. The occurrence of one type of response or another depends on the intensity and duration of the stress applied, the susceptibility of the species that are exposed and/or the route of exposure (Bebianno et al, 2005;Sanchez et al, 2005).…”

“…The occurrence of one type of response or another depends on the intensity and duration of the stress applied, the susceptibility of the species that are exposed and/or the route of exposure (Bebianno et al, 2005;Sanchez et al, 2005). Furthermore, CAT activity may be species-specific (Fonseca et al, 2011;Madeira et al, 2013Madeira et al, , 2014 and tissuespecific (Viera et al, 2012;Vinagre et al, 2014). In the present study, it can be observed that the association between the two conditions (temperature and Mn 2+ ) to which the fat snook specimens were exposed induced the activation of the catalase enzyme, and therefore, induced the activation of the oxidation system.…”

This study evaluates the effects of exposure to manganese (Mn 2+ ) for 96 hours at two different temperatures (24 and 27°C) on juveniles of Centropomus parallelus through the activities of glutathione S-transferase (GST) and catalase (CAT), micronuclei test (MN) and comet assay. The GST activity did not show any significant difference between the groups exposed to Mn 2+ and the respective control groups; in contrast, a major increase in the CAT activity was observed at 27°C in the group exposed to Mn 2+ compared to the control group. The genotoxic analyses showed that in all animals exposed to Mn 2+, the number of red cells with micronuclei increased significantly compared to the respective control groups. There was also a significant increase in the incidence of DNA damage in the groups exposed to Mn 2+. At a temperature of 24ºC, animals exposed to Mn 2+ had more DNA damage than those at 27°C. It is likely that the increase in temperature can also induce oxidative stress. Thus, we conclude that manganese is toxic to the fat snook juveniles, causing genotoxic damage, and when associated with an increase in temperature, manganese can also provoke an increase in oxidative stress.Keywords: Biomarkers, DNA damage, Enzymes, Genotoxicity, Metal, Micronuclei.Este estudo avaliou os efeitos da exposição ao manganês (Mn 2+ ), após 96 horas, a duas temperaturas (24 e 27°C) em juvenis de Centropomus parallelus por meio de análises bioquímicas (atividade das enzimas glutationa S-transferase (GST) e catalase (CAT)) e genotóxicas (teste do micronúcleo e ensaio cometa). A atividade da GST não mostrou diferença significativa entre os grupos expostos ao Mn 2+ e os seus respectivos grupos controle, enquanto que um aumento significativo na atividade da CAT foi observado a 27°C no grupo exposto ao Mn 2+ , quando comparado ao grupo controle. As análises genotóxicas mostraram que os animais expostos ao Mn 2+ tiveram aumento significativo na quantidade de células com micronúcleo em relação aos seus grupos de controles. Houve também aumento significativo na incidência de danos ao DNA nos grupos expostos a esse contaminante. Na temperatura de 24°C, os animais expostos ao Mn 2+ tiveram maior quantidade de danos no DNA em relação a 27°C. É provável que o aumento da temperatura também possa induzir o estresse oxidativo. Assim, concluímos que o manganês é tóxico para os juvenis de robalo, causando dano genotóxico, e quando associado a um aumento da temperatura, também pode provocar um aumento no estresse oxidativo.
