Effect of UV exposure on the antioxidant capacity measured in four brown algae collected at different depth in Fildes Bay.

<p>Algae were exposed for 6 h to PAR+UV-A+UV-B and PAR conditions (20 μmol m^-2 s^-1 for PAR, 3 W m^-2 for UV-A and 0.25 W m^-2). Initial is the time cero before the 6 h exposure to UV radiation. Values are means ± S.D., n = 3. Similar letters connect homogeneous mean groups for each species after two-way ANOVA and Tukey’s HSD.
