Fig. 3: Relationship between performance, forebrain and cerebellum cell count measurements, and population density.
From: Brain morphology predicts social intelligence in wild cleaner fish
Scatterplots of a forebrain cell proportion from the total brain cell count, b forebrain cell density, c cerebellum cell proportion from the total brain cell count, and d cerebellum cell density. The p-value indicates significant (p < 0.05, GLMs) interaction between cerebellum density and cleaner population. R coefficient refers to the Pearson correlation coefficient. Red triangles refer to failure while blue circles refer to success in the biological market task. Sample size in a, c and d is n = 20 biologically independent animals. In b, there is n = 18 biologically independent animals.
