Inter-individual behavioural variation in the crested porcupine

In this study, we investigated on the existence of personality in the crested porcupine in Central Italy by measuring variation and repeatability of three behavioural traits. Porcupines were captured through metal traps located around and in the immediate surroundings of the burrows. Then, they were manipulated and set free. Capture and handling were the experimental contexts where we measured exploration, proactivity and aggressivenessof each individual. Our results provided evidence for consistent inter-individual differences in the measured traits, with a high value of individual repeatability in aggressiveness and proactivity. The positive correlation between traits suggest the existence of a behavioural syndrome, with some individuals more aggressive and active with respect to others.
