From: Individuality in nutritional preferences: a multi-level approach in field crickets
(a) The among-individual correlation (n = 82 individual means) and (b) the within-individual correlation (n = 383 observations) between carbohydrate and protein intake, and (c) the among-individual correlation (n = 82 individual means) and (d) the within-individual correlation (n = 383 observations) between body weight and nutritional preference in Southern field crickets. Following31, the plot of the among-individual correlation is visualized as the correlation between means of each individual’s z-transformed phenotypes; the within-individual correlation is visualized as the correlation between the z-transformed deviations of each observation from a focal individual’s mean for both phenotypes. Larger values of nutritional preference indicate that individuals prefer more carbohydrates over proteins.
