Additionally, global warming leads to elevation of water temperature can affect the biochemical reactions of ectotherms. It is, thus, important to realize weather elevated temperature would impose the harmful effects of copper on cellular regulation and viability of aquatic animals. Poeciliidae families have been employed as sentinel species in ecotoxicological studies. In light of the background above, the present study aimed to investigate the cellular stress response of sail-fin molly (Poecilia latipinna) acutely exposed to ecologically relevant copper levels under elevated temperature scenario. The cellular stress responses, protein quality control and antioxidant defense as the biomarker were examined in gills and liver. The results showed that either copper or thermal challenge indeed triggered cellular stress responses. However, the condition of combined stresses would suppress a part of cellular stress responses resulting in intense cell damage as elevation of aggregated proteins to sail-fin molly. Accordingly, in the perspective, global warming will impose the toxicological damage of copper which may affect the cellular and physiological homeostasis of aquatic animals and the health of aquatic ecosystems.
