Contrasting neurochemical and behavioral profiles reflects stress coping styles but not stress responsiveness in farmed gilthead seabream (Sparus aurata)
Höglund, Erik; Moltesen, Maria; Castanheira, Maria Filipa; Thörnqvist, Per-Ove; Silva, Patricia IM; Øverli, Øyvind; Martins, Catarina; Winberg, Svante (Peer reviewed; Journal article, 2020)In fish, as well as in other vertebrates, contrasting suites of physiological and behavioral traits, or coping styles, are often shown in response to stressors. However, the magnitude of the response (i.e. stress responsiveness) ... -
