在许多动物物种中,个体竞争繁殖领土的唯一所有权,而在其他物种中,公共领土由同性同种共享。在什么条件下自然选择有利于个体领土性的进化,在什么条件下自然选择有利于社会性的进化?我们开发了一个自洽的博弈论模型,允许进化和种群动态之间的反馈。在这个模型中,非居民流动者可以在三种策略中做出选择:他们可以等待领土空缺的出现,他们可以试图强行接管已经被占领的领土,或者他们可以与已建立的居民分享领土。我们发现,竞争环境最初有利于侵略性(领土)战略的演变。然而,随着竞争的进一步加剧,从侵略性战略转向社会性战略。此外,领土所有者(居民)对飞蚊症的行为作出反应,从而产生反馈,其中居民调整其对飞蚊症攻击水平的容忍程度,反之亦然。这种反馈类似于生物市场的动态,最终导致群体中侵略性和社会流动性策略的共存。这种混合平衡在自然界中经常发生。
In many animal species individuals compete for the sole possession of a breeding territory, whereas in other species communal territories are shared among same-sex conspecifics. Under what conditions does natural selection favor the evolution of individual territoriality, and under what conditions does it favor the evolution of sociality? We develop a self-consistent game-theoretic model that allows for feedbacks between evolutionary and population dynamics. In this model, nonresident floaters can chose between three strategies: they can wait for a territory vacancy to arise, they can try to forcefully take over an already-occupied territory, or they can share a territory with an established resident. We show that competitive environments initially favor the evolution of an aggressive (territorial) strategy. Yet as competition increases further, a shift occurs from aggressive to social strategies. Moreover, territory owners (residents) respond to the behavior of floaters, such that a feedback occurs in which residents adjust their degree of tolerance to the level of floater aggression and vice versa. This feedback resembles the dynamics of a biological market and eventually leads to the coexistence of aggressive and social floater strategies in the population. Such mixed equilibria commonly occur in nature.
