title: Seasonal Dynamics of Catalase Activity in <i>Cystoseira crinita</i> (Black Sea) and <i>Fucus vesiculosus</i> (Barents Sea)
abstract: Abstract The seasonal dynamics of catalase activity of two related species of brown macroalgae, Cystoseira crinita (Desf.) Bory (1832) and Fucus vesiculosus L. (1753) was studied. In general, catalase activity (CA) in C. crinita was several times higher than in F. vesiculosus . The maximum values of CA in C. crinita were observed in November and the minimum ones in September. For F. vesiculosus , the maximum CA was found in January and the minimum in April. Abrupt changes in water temperature si
