Cell numbers (cells L -1 ) estimated by qPCR for Az . spinosum (black bars) and Am . languida (grey bars) for the six transects (T1 –T6) shown in Fig 1B.

Cell number calculation based on mean C T values of three technical replicates. The peak cell density (> 120,000 cells L -1 ) of Am . languida at station 71 is not shown, but indicated by the grey asterisk in T6.
