Long-term, multi-institution evaluations have become a reliable assessment tool for evaluating patterns of wounding in zoo-living primates, informing on each species’ respective care and population management. For western lowland gorillas (Gorilla gorilla gorilla) there has been no detailed reports focused on mixed-sex groups, the most common social group type for this species in zoos. In this study, wounding data were collected over 24 months for 131 gorillas living in 26 social groups at 18 zoos and analyzed in relation to age, sex, and group demographic variables. Adult females received wounds at significantly higher rates than adult males suggesting sexual dimorphism and the disparate social roles of male and female gorillas may differentially affect wounding rates. Group size was positively associated with wounding in adult gorillas, however, wounding rates overall were low in frequency and severity. Wound locations were not randomly located, with wounds to the trunk of body accounting for 24% of all wounds. These data provide useful insights that may help inform and improve management of gorillas in mixed-sex groups. Specifically, understanding that vulnerability to wounding may be more prevalent in females compared to males can inform strategies aimed at improving husbandry, health, and welfare and have a positive impact on population management practices for the species.

长期的，多机构的评估已成为一种可靠的评估工具，用于评估动物园中生活的灵长类动物的伤害方式，并告知每个物种各自的照顾和种群管理情况。对于西部低地大猩猩（大猩猩大猩猩）尚无针对混合性别群体的详细报告，而混合性别群体是动物园中该物种最常见的社会群体类型。在这项研究中，在24个月内收集了18个动物园中26个社会群体中的131只大猩猩的受伤数据，并分析了其年龄，性别和群体人口统计变量。成年女性的伤口发生率明显高于成年男性，这表明性二态性以及大猩猩和雌性大猩猩的不同社会角色可能会不同地影响伤口的发生率。组的大小与成年大猩猩的伤口成正相关，但是总体上伤口的发生率和严重性较低。伤口位置并非随机分布，身体躯干伤口占所有伤口的24％。这些数据提供了有用的见解，可帮助告知和改善混合性大猩猩群体中的大猩猩管理。具体而言，了解到女性比男性更容易受伤的观点可以为旨在改善畜牧业，健康和福利的战略提供信息，并对该物种的种群管理实践产生积极影响。
