Posterior distributions and boxplots comparing the relative proportion of three food categories (animal, C3 plant and C4 plant) between two genera of rodents (rice rats [Oryzomys] and black rats [Rattus]) in each of two islands in southern Florida, USA (the Lower Keys and Sanibel-Captiva; 2021). Included in each panel is the probability (P) that the food item’s proportional composition of diet is greater for one genus when compared to the other.
