Ventral scent-marking in the male Mongolian gerbil, Meriones unguiculatus, may be related to reproductive potential. In four experiments involving nine groups, males' marking during 5-min. open field tests correlated with their social and reproductive status. The lowest levels of marking occurred among individually housed or subordinate males of a pair, followed by males exposed to ovariectomized females, and dominant males of a pair. Higher levels of marking occurred with vasectomized males living with intact females or following the removal of males from a nuclear family. The most frequent marking occurred when males were housed with pregnant females and with females and their offspring. The proximate stimuli leading to high marking appear to be the sexual availability of reproductively competent females.
雄性长爪沙鼠（Meriones unguiculatus）的腹部气味标记可能与繁殖潜力有关。在涉及9个组的4项实验中，雄性在5分钟旷场试验中的标记行为与其社会和繁殖状态相关。标记水平最低的是单独饲养的雄性或配对中的从属雄性，其次是接触过卵巢切除雌性的雄性以及配对中的优势雄性。与完整雌性一起生活的输精管切除雄性或从核心家庭中移除雄性后，标记水平较高。当雄性与怀孕雌性以及雌性及其后代一起饲养时，标记最为频繁。导致高标记行为的直接刺激因素似乎是具有生殖能力的雌性的性可获得性。
