Dataset and R Script - cuttlefish oxidative stress and extreme flooding events

The marine environment is undergoing major changes, mainly due to climate change, which has increased the frequency and intensity of extreme events. Here, we aimed to study the impact of ecologically relevant extreme flooding conditions (exposure to acute salinity values of 17 and 7) and non-extreme conditions (salinity values of 35, 28, and 24), during 4 days at late embryogenesis, on the oxidative stress of the European cuttlefish (Sepia officinalis) hatchlings. The oxidative stress was evaluated by assessing biomarkers, including heat-shock proteins (HSP70), DNA damage (8-OHdG) and total ubiquitin (Ubi) concentrations, as well as the activity of antioxidant enzymes, Total Antioxidant Capacity (TAC).Here we show, for the first time, that short-term extreme flooding conditions elicit harmful effects on cuttlefish early ontogeny at physiological levels.
