Torres Dowdall et al. 11-0833 Water colum data

Data use in the analysis of water column use. Data correspond to proportion of guppies (Poecilia reticulata) using the surface of the water column. Drainage refer to the drainage from were wild fish used to generate second generation of lab-reared experimental fish were collected. Predation refers to the community from which the wild caught fish were collected. "low" represent low predation risk, simple fish communities. "High" refer to downstream complex communities where predation risk is higher. Family refers to the family lines used in the experiment. "trt" refers to the two treatments used in our experiment. "P" means that fish were reared in the presence of predator cues, "NP" means that they were raised in the absence of such cues. Only significant interactions between terms were kept in the final model.
