Fig. 4: Relationship between locally adaptive behavioural strategies, forebrain and cerebellum measurements, and population density.
From: Brain morphology predicts social intelligence in wild cleaner fish
Scatterplots of a forebrain size proportion, b cerebellum size proportion, and c cerebellum cell densities. Cleaner performance is categorised here as either optimal or not-optimal strategies as a function of population density (see ‘Methods’ section). The p-value indicates significant (p < 0.05, GLM) differences in forebrain size between individuals with optimal strategies and those with not-optimal strategies. R coefficient refers to the Pearson correlation coefficient. Green circles refer to optimal strategies while brown triangles refer to not-optimal strategies within social competence context. Sample size in a and b is n = 18 biologically independent animals. In c, there is n = 20 biologically independent animals.
