Table 2.

Results of a PCA including the number of sniffs, puffs and bites exhibited by ASL females towards pup models representing different age-classes. The PCA compiled three PC, with only PC1 scoring an eigenvalue >1. PC1 was positively correlated with aggressive behaviours and explained 57% of the variance in female response.
