Figure 4.
Relative medial cortex volume ± SE (least squares means from the model with telencephalon volume as the covariate) across three male morph types. Orange males defend large territories (n = 9), blue males defend smaller territories (n = 8), while yellow males do not defend territories and have smaller home ranges than orange and blue males (n = 7). There was not a significant effect of morph on relative medial cortex volume, but mean values showed perfect correlation with the morph.
