Effects of plastic waste on morphological and life history parameters of D. longicephala: (A) body length of daphnids exposed to kairomones; (B) crest width of daphnids exposed to kairomones; (C) duration in days until daphnids reach primiparity when exposed to kairomones. (D) body length of daphnids exposed to control medium; (E) crest width of daphnids exposed to control medium; (F) duration in days until daphnids reach primiparity when exposed to control medium. Error bars indicate standard error of means (±1SE). Asterisks represent level of significance when treatments are compared with induction (I) or control (C) treatments: n.s. = p ≥ 0.05; *p ≤ 0.05; ***p ≤ 0.001.
