The impact of artificial light pollution at night on the life history parameters of rotifer Brachionus plicatilis with different food experiences

Artificial light at night (ALAN) may pose threat to rotifer Brachionus plicatilis . Additionally, the food of rotifer, i.e. algal community composition, often fluctuates. Thus, we selected five wavelengths of ALAN (purple, blue, green, red, white) and a three -colored light flashing mode (3 -Flash) to test their impacts on life history traits of B. plicatilis with different food experiences, including those feeding Chlorella vulgaris (R C ) or Phaeocystis globosa (R P ). Results indicated purple ALAN promoted R C development, white ALAN inhibited R C development, while 3Flash and white ALAN promoted R P development. Under red and white ALAN, R P increased fecundity but decreased lifespan. High -quality food enhanced rotifer's resistance to the impact of ALAN on lifespan. ALAN and food experience interacted on B. plicatilis . The effect of blue ALAN has less negative effects on B. plicatilis , based on hierarchical cluster analysis. Such findings are helpful to evaluate the potential impact of ALAN on marine zooplankton.
