D. magna was raised either in a predator-free environment ('Calibrator') or in incubation water of Leucaspius delineatus (sunbleak, 'Vertebrate 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.
