雄性巴巴里猕猴 (Macaca sylvanus) 的社会等级、交配努力和繁殖成功之间的关联已通过长期行为观察和随后通过寡核苷酸 DNA 指纹识别在一个大型半自由放养群体中进行亲子鉴定来评估。 1985 年至 1988 年间出生且存活至少 1 岁的所有后代 (n=75) 均可进行亲子鉴定。在 70 例 (93%) 的案例中，除了一名潜在父亲外，所有其他人都可能被排除在亲子关系之外。使用即兴记录来记录交配活动。和重点女性抽样技术。对雄性交配努力的分析仅限于最有可能受孕的日子。雄性排名与所有四个繁殖季节的雄性交配成功率以及四个季节中的三个季节的雄性繁殖成功率显着相关。交配成功率和繁殖成功率也显示出显着的相关性，但有一个繁殖季节除外，其中雄性与可受精雌性的比例特别高。交配成功率低几乎总是与繁殖成功率低相关，而交配成功率高则无法预测雄性实际的繁殖成功率。这显然是混交交配系统导致的精子竞争的结果。只要有足够的样本量并且可以确定受孕期，雄性交配成功不一定是繁殖成功的不可靠指标。然而，精子竞争和其他因素可能会削弱这种关联。
The association between social rank, mating effort, and reproductive success of male Barbary macaques (Macaca sylvanus) has been evaluated by longterm behavioral observations and subsequent paternity determination via oligonucleotide DNA fingerprinting in a large semifreeranging group. All offspring born between 1985 and 1988 that survived to at least 1 year of age (n=75) were available for paternity testing. The exclusion of all but one of the potential fathers from paternity was possible in 70 cases (93%). Mating activities were recorded using ad lib. and focal female sampling techniques. The analysis of male mating effort was restricted to the most likely days of conception. Male rank correlated significantly with male mating success in all four breeding seasons and with male reproductive success in three of the four seasons. Mating success and reproductive success also showed a significant correlation, with the exception of one breeding season, in which the proportion of males per fertilizable female was especially high. Poor mating success was almost always associated with poor reproductive success, while good mating success was less predictive for a male's actual reproductive success. This was apparently a consequence of sperm competition, resulting from the promiscuous mating system. Male mating success is not necessarily an unreliable indicator for reproductive success, provided that sufficient sample sizes are available and that conception periods can be determined. Sperm competition and other factors may weaken the association, however.
