In South Africa, lions are protected in national parks and smaller fenced reserves. Translocating lions between fenced reserves, whilst necessary to maintain genetic diversity, is disruptive and can impact survivorship and pride cohesion. Critical to translocation success is pride cohesion. White lions are a natural colour variant occurring in the Greater Kruger Park Region, where anthropogenic threats eliminated this population until reintroduction in 2006. Through social network analysis (SNA), the sociality of a released pride of captive-origin white and wild tawny lions was compared to two captive-origin and wild prides of tawny lions. Social interactions and pride dynamics were recorded for each pride. For all prides, cubs and subadults were central to the play network, while adults received the most social interactions. White and wild tawny adult males initiated more social interactions than captive-origin tawny males, whilst a keystone adult female was identified in each pride. For the constructed pride, social interactions were more evenly distributed, suggesting a high level of connectedness and cohesion. This is the first study to demonstrate that captive-origin white and wild tawny lions can form a socially functional pride, suggesting that white lions would survive in the wild in the absence of anthropogenic threats.
在南非,狮子在国家公园和较小的围栏保护区中受到保护。在围栏保护区之间转移狮子,虽然对于维持遗传多样性是必要的,但具有破坏性,并且可能影响生存能力和狮群凝聚力。转移成功的关键在于狮群凝聚力。白狮是大克鲁格公园地区出现的一种自然毛色变种,在该地区,人为威胁导致这个种群灭绝,直到2006年重新引入。通过社会网络分析(SNA),将一群圈养来源的白狮和野生黄褐色狮子放归后的社会性,与两群圈养来源和野生的黄褐色狮子进行了比较。记录了每个狮群的社会互动和狮群动态。对于所有狮群来说,幼崽和亚成年个体在玩耍网络中处于核心位置,而成年个体接受的社会互动最多。白狮和野生黄褐色成年雄性发起的社会互动比圈养来源的黄褐色雄性更多,同时在每个狮群中都识别出了一只关键成年雌性。对于组建的狮群,社会互动分布更为均匀,表明其具有高度的连通性和凝聚力。这是第一项证明圈养来源的白狮和野生黄褐色狮子能够形成具有社会功能的狮群的研究,这表明在没有人为威胁的情况下,白狮能够在野外生存。
