Physiological response of the sea urchin Paracentrotus lividus fed with the seagrass Posidonia oceanica and the alien algae Caulerpa racemosa and Lophocladia lallemandii
چکیده انگلیسی

The aim was to determine the effects of alien algae feeding on biomarkers of oxidative stress in the sea urchin Paracentrotus lividus. Sea urchins were fed during three months with the native seagrass Posidonia oceanica, and the alien macroalgae Caulerpa racemosa and Lophocladia lallemandii and biochemical analysis were performed in the gonads. A control group was immediately processed after sampling from the sea. Antioxidant enzyme and glutathione S-transferase activities and GSH concentration were significantly higher in sea urchins fed with alien algae when compared with the control group and the one fed with P. oceanica group. This response was more intense in the group fed with L. lallemandii respect to the C. racemosa group. The concentration of MDA, protein carbonyl derivates and 8-OHdG reported no significant differences between treatments. In conclusion, the invasive algae C. racemosa and L. lallemandii induced an antioxidant response in P. lividus without evident oxidative damage.


► Feeding Caulerpa racemosa and Lophocladia lallemandii induces an antioxidant response in the sea urchin Paracentrotus lividus.
► L. lallemandii feeding induces a more intense antioxidant response than C. racemosa.
► No significant oxidative damage was evidenced after alien algae intake.
