Abstract

In the present study, we investigated morphological changes of hatchlings from asexually and sexually produced eggs of Daphnia galeata and D. similis against fish kairomones. In both species, hatchlings from asexual eggs showed induced traits, such as short body length, long tail spine and high relative tail spine length when influenced by fish kairomones. However, hatchlings from sexual eggs expressed high relative tail spine length regardless of kairomones presence. The results showed that the inducibility of morphological defences depends on the egg type, with inducible defences predominant in asexual eggs while fixed defences are employed by the offspring of sexual eggs in Daphnia.
