Abstract: Survival and reproduction are the nature of animals, and copulation is the key process of sexually reproducing animals, which could be shaped by natural selection and sexual selection. However, it is difficult to observe copulation in the wild, and therefore there is lack of quantitative analyses of wildlife’copulation. In this study, a troop of free-ranging Taihangshan macaques (Macaca mulatta tcheliensis) was assigned as the study object, and the data of copulation was collected through focal-animal sampling and analyzed within the Macaca genus. The results showed that, (1) the social grooming (49. 8%) was the dominant pre-copulation behavior and initiated by adult females (61. 8%); (2) a copulation cycle was composed of 12 mounting bouts and a successful ejaculation, lasting (719. 4 ± 43. 3) s on average, and the copulation pattern of Taihangshan macaque could be classified as multiple-mount-to-ejaculation pattern; (3) social grooming (19. 4%) and resting (18. 1%) were the main behaviors during the post-copulation period, and the copulation bond could last (2. 1 ± 2. 03) d; (4) the copulation patterns of used macaque species were consistent with the phylogenetic relationship and the traditional taxonomic classification rather than with social style, while the copulatory parameters varied among species. This study quantitatively analyzed the copulatory behaviors, and the copulation patterns of macaque species were relatively conserved according to the phylogenetic relationship and traditional taxonomic classification.

摘要: 生存和繁衍是动物的本能,交配则是营有性繁殖动物成功繁殖的前提,亦是自然选择和性选择的重要作用环节。由于在自然条件下较难观察交配行为,故而相对缺乏有关野生动物交配行为的量化分析。本研究以济源五龙口地区的太行山猕猴(Macaca mulatta tcheliensis) WLK-1A群为对象,利用焦点动物取样法,采集了太行山猕猴交配行为数据,并对其进行了量化分析,进而与近缘物种作了比较。研究结果显示,(1)太行山猕猴的交配前行为以社会理毛为主(49.8%),且多由雌性发起(61.8%);(2)太行山猕猴的交配模式属于多次爬跨射精型,一次完整的交配过程包括12个爬跨回合和1次射精,持续时长平均为(719.4 ± 43.3) s;(3)交配后行为以社会理毛(19.4%)和休息(18.1%)为主,雌雄个体交配关系可持续平均(2.1 ± 2.03) d;(4)猕猴属(Macaca)物种的交配参数存在种间差异,交配模式与系统发育关系和分类群组基本吻合,但与社会风格关系不甚明显。本研究结果为全面理解猕猴属物种的繁殖生态学特征提供了基础数据。
