Zusammenfassung:
Size, age and number of offspring at the first and subsequent two reproductions were compared in Daphnia treated with cues from invertebrate predators (adult Cyclopoida fed Daphnia) and from crushed conspecifics. Daphnia in the presence of invertebrate predators had earlier maturation, greater size at first and subsequent reproductions and a larger number of offspring than control animals, while the opposite (later maturation and smaller size at subsequent reproductions) happened when Daphnia were treated with homogenate from crushed conspecifics
