爱情迷宫让雌性狨猴选择伴侣
狨猴(Callithrix jacchus)越来越多地被用于生物医学研究,但商业供应商一直难以为大型项目提供足够的动物。因此,许多实验室不得不通过繁殖动物来建立自己的狨猴群落。然而,繁殖相当困难且耗时,雌性狨猴的繁殖效率也不高。目前的系统是随机建立一对雌雄繁殖配对,而这对配对往往需要很长时间才能成功繁殖;配对的雌雄狨猴还可能因为打斗或攻击而不相容。在最近的一份预印本(未经同行评审)中,Drazan 等人提出了一种允许雌性圈养狨猴选择伴侣的方案。这种新颖的伴侣偏好测试(或称 "爱情迷宫")一次向雌性狨猴展示两个潜在的雄性候选者,研究人员可以观察雌性狨猴对这两个雄性候选者的行为,从而确定雌性狨猴更喜欢哪一个。对选定的雄性多次重复这一过程,并每次提供新的雄性选项,以确保雌性对这一伴侣有明确的偏好。这种方法成功地将受孕潜伏期缩短到随机配对所需时间的一半左右,并将繁殖成功率提高了约 2.5 倍。这种简单的伴侣偏好协议可以为狨猴群落的繁殖计划提供一种省时高效的方法,为实验提供适当的样本量:Drazan, T.M. et al. preprint at bioRxiv https://doi.org/10.1101/2024.05.08.593247 (2024)

期刊介绍: LabAnimal is a Nature Research journal dedicated to in vivo science and technology that improves our basic understanding and use of model organisms of human health and disease. In addition to basic research, methods and technologies, LabAnimal also covers important news, business and regulatory matters that impact the development and application of model organisms for preclinical research. LabAnimal's focus is on innovative in vivo methods, research and technology covering a wide range of model organisms. Our broad scope ensures that the work we publish reaches the widest possible audience. LabAnimal provides a rigorous and fair peer review of manuscripts, high standards for copyediting and production, and efficient publication.
