Figure 3

Mean (±S.E.) total ash free dry weight productivity (g m−2 day−1) of monoculture, bi-culture and polyculture combinations of three macroalgae grown under three stocking densities (low, medium, and high) in A) Week 1, B) Week 2 and C) Week 3 of the competition experiment. OE: Oedogonium monoculture (control); CL-OE: Cladophora – Oedogonium bi-culture; SP-OE: Spirogyra – Oedogonium bi-culture; P: Polyculture of all three species.
