Fig. 4.

Relative abundance of phototrophic taxa between collection times at the sample site and at 36 DAT. Different phototrophic taxa are denoted by different colours and taxa comprising <1% of the relative abundance are listed under other. Analysis was carried out on fresh water (a) and sediment (b), water in illuminated (c) and dark (d) water-sediment microcosms, sediment in illuminated (e) and dark (f) water-sediment microcosms, and water in illuminated (g) and dark (h) water-only microcosms at 36 DAT.
