Schematically drawing of experimental setup: Orange encircled treatments represent the kairomone (from notonectid predators – top left) exposed daphnids. (I), plastic-free, solely kairomone-containing; (I + HDPE; I + PET kairomone and the respective plastic. (I + GLASS) positive surface control to the plastic treatments. Orange asterisks indicate kairomones. Blue encircled treatments represent the daphnids exposed to kairomone free medium. (C), plastic- and kairomone free, (C + HDPE, C + PET) only plastic, in order to exclude effects caused by plastic; (C + GLASS) only glass, in order to exclude effects caused by glass.
