Abstract excerpt

Animals vary consistently in traits such as boldness and stress reactivity, which influence fitness, movement, and social dynamics. Identifying genetic variants linked to these behaviours can clarify proximate mechanisms and evolutionary trade-offs. Dopaminergic (DRD4) and serotonergic (TPH2) pathways are known to modulate exploration and emotionality, while LDHA contributes to neuroenergetics and endurance, yet...
