Light regime throughout the experiment. Light intensities, in lux, against clock time throughout the day. The dark line depicts “control” (L16:D8h) and the grey line refers to “low-light” regime. Arrows delimit sampling times that were used as biological replicates after preliminary alanysis (see text). Before “low-light” (L16 + Llow3:D8h) regime reached the constant additional light at night level (300 lux), light intensity smoothly droped to 50 lux. “Control” light regime decreased to darkness uninterrupted
