Ocean acidification affects the expression of neuroplasticity and neuromodulati...
A Costa, Rita; Olvera, Aurora; Power, Deborah Mary; Velez, ZéliaA possible explanation for acidification-induced changes in fish behaviour is that acidification interferes with neurogenesis and modifies the plasticity of neuronal circuitry in the brain. We tested the effects on the olfactory system and brain of gilthead seabream (Sparus aurata) to 4 weeks' exposure to ocean acidification (OA). Olfactory epithelium (OE) morphology changed shortly after OA exposure and persis...
Thermal imprinting modifies adult stress and innate immune responsiveness in th...
Mateus, Ana; A Costa, Rita; Cardoso, João CR; Andree, Karl B.; Estevez, Alicia; Gisbert, Enric; Power, DeborahThe impact of thermal imprinting on the plasticity of the hypothalamic-pituitary-interrenal (HPI) axis and stress response in an adult ectotherm, the gilthead sea bream (Sparus aurata, L.), during its development was assessed. Fish were reared under 4 thermal regimes, and the resulting adults exposed to acute confinement stress and plasma cortisol levels and genes of the HPI axis were monitored. Changes in immu...
