D. magna was raised in either a predator-free environment ('Calibrator'), or in incubation water of larvae of Chaoborus flavicans ('Invertebrate predator').

aValues are mean of n = 3 replicates ± SD. Expression levels are displayed relative to the mean control level

bSD is the variation of one reference gene across treatments
