Negative correlation between the regional average densities of perfused subepidermal capillaries for nonbreeding males (nbM) and the differences in such densities between breeding and nonbreeding males (bM − nbM). n = 3 for both seasons. rS: Pearson correlation coefficient. Unit: capillaries per millimeter of epidermis. 1: dorsal head; 2: back; 3: dorsal forearm; 4: dorsal distal hindlimb; 5: lateral abdomen; 6: ventral head; 7: chest; 8: posterior belly; 9: ventral forearm; 10: ventral proximal hindlimb
