PDF, dataset and R script for the paper: Tariel J, Plénet S, & Luquet E. Transgenerational plasticity of inducible defenses: combined effects of grand-parental, parental and current environments. bioRxiv 589945, ver. 3 peer-reviewed and recommended by PCI Evolutionary Biology (2019). https://doi.org/10.1101/589945 Two data sets are provided: one for the analysis of the behavior (dataBehaviour.csv) and one for the analysis of other variables (weight, shell thickness and morphology; dataMorphology.csv). There are analyzed in the same R script (Script_TARIEL-Juliette.R) Signification of variables names: G1: treatment/environment of the grand-parental generation (control C or with predator-cue P) G2: treatment/environment of the parental generation (control C or with predator-cue P) G3: treatment/environment of the offspring generation (control C or with predator-cue P) Family: unique ID for each family Individual: number to identify siblings within a family ID: unique ID for each individual W: snail total weight (g) Th: shell thickness (mm) L: shell length (mm) l: shell width (mm) Lo: aperture length (mm) lo: aperture width (mm) crawlout : position of the snail (0: below the water surface; 1: above/on the water surface) Day : day of measurement (crawling-out behaviour was measured three times through three consecutives days d2, d3 and d4)
