The study aims to explore how individual differences in behavior among wolf cubs relate to physiological responses such as heart rate and cortisol levels.
Cubs from two litters were tested for exploratory behavior, prey killing ability, and social dominance.
Heart rate was monitored biotelemetrically to assess emotional reactivity during tests.
Blood samples were collected for cortisol analysis under stress conditions including confinement and ACTH injection.
High-ranking cubs exhibited greater sympathetic tone with higher resting EKG and stronger adrenal-pituitary responses to stress.
Cub behavior scores correlated with physiological responses; higher scores were associated with stronger sympathetic reactivity and cortisol responses.
Middle-ranking cubs had greater sympathetic tone under stress compared to low-ranking cubs, showing a quicker and more robust cortisol response.
