Caption
Wheat field in early spring and autumn. The lower temperatures and earlier bare soil were conditions fa-voured yellow-green algae making them the most diverse and abundant algae in this farmland at that time, followed by diatoms (single-celled algae). The insert on the right (a) shows a close up of the soil with dense cover of filaments. The close up on the left (b) shows algae which have tube-like filaments as well as single-celled algae.
