Abstract

Abstract: The introduction of invasive species can lead to significant adverse effects on the colonized areas. The aim of the present research was to determine if the invasive behavior of Paraleucilla magna could induce the activation of the antioxidant defences in the native red algae, Peyssonnelia squamaria . Individuals of isolated P. squamaria and individuals epiphytized by P. magna, both growing on rocky bottoms, were collected. The activity of the antioxidant enzymes - catalase, superoxide dismutase, glutathione peroxidase and glutathione reductase – and the levels of the malondialdehyde were significantly higher in the algae of the epiphytic group compared to the control group, while the detoxifying enzyme glutathione S -transferase did not show significant differences. The levels of reduced glutathione and total polyphenols were higher in the algae affected by the sponge. In conclusion, the arrival of the species P. magna induces an adaptative antioxidant response in P. squamaria determined by the use of biomarkers. Graphical abstract: Image 1 Highlights: Paraleucilla magna is an invasive calcareous sponge in the Mediterranean Sea. P. magna may grow over native species such as the red algae Peyssonnelia squamaria. The antioxidant machinery was induced in P. squamaria epiphytized by P. magna. No changes in lipid peroxidation were found in P. squamaria affected by P. magna.
