Data use in the analysis of size at maturity. Data correspond to size at maturity of lab-reared male guppies (Poecilia reticulata). Size was measured as standard length of the fish (length column). Drainage refer to the drainage from were wild fish used to generate second generation of lab-reared experimental fish were collected. Pred refers to the community from which the wild caught fish were collected. LP represent low predation risk, simple fish communities. HP refer to downstream complex communities where predation risk is higher. Family refers to the family lines used in the experiment. Cue refers to the two treatments used in our experiment. hp means that fish were reared in the presence of predator cues, lp means that they were raised in the absence of such cues. Only significant interactions between terms were kept in the final model
