在许多有蹄类动物的战斗中，鹿角起到了主要武器的作用。我们研究了鹿角损伤与(I)竞争动态：在战斗中使用的行为战术，包括战斗持续时间，以及(Ii)交配成功率、战斗率和优势之间的关系。鹿角的结构性损伤与比赛动态有关：损伤与鹿角受损的个体的跳跃碰撞攻击负相关，而对手更有可能在战斗中用受损的鹿角取代个体的身体。我们发现支配地位和损害之间存在正相关关系，这表明地位较高的个体鹿角可能会受到破坏。我们没有发现任何证据表明伤害与交配成功或个体参与打架的次数有关。我们的研究为理解竞赛动态和武器结构之间的联系提供了一个新的视角，同时也表明损害对个人健康的影响有限。
Antlers function as primary weapons during fights for many species of ungulate. We examined the association between antler damage and (i) contest dynamics: the behavioural tactics used during fighting including fight duration, and (ii) mating success, fighting rate and dominance. Structural damage of the antlers was associated with contest dynamics: damage was negatively associated with jump clash attacks by individuals with damaged antlers, whereas opponents were more likely to physically displace individuals with damaged antlers during fighting. We found a positive association between dominance and damage indicating that high-ranking individuals were likely to have breaks to their antlers. We found no evidence that damage was associated with either mating success or the number of fights individuals engaged in. Our study provides a new perspective on understanding the association between contest dynamics and weapon structure, while also showing that damage has limited fitness consequences for individuals.
