我们研究了社会对 240 窝蒙古沙鼠 Meriones unguiculatus 雌性成员首次生育年龄的影响。结果表明：（1）姐妹会抑制彼此的生殖发育，尽管这种相互抑制在年长、生殖活跃的雌性存在时比不存在时表现得更强烈，（2）雄性沙鼠和它们帮助饲养的雌性之间会出现性不相容，或者雌性沙鼠需要接触陌生的雄性才能使其生殖发育进行到性成熟，（3）成年雄性沙鼠与年轻雌性的接触会增加雄性随后的受孕潜伏期除了那些暴露于男性的女性之外。总而言之，这些结果表明，生活在家庭群体中的雌性蒙古沙鼠的首次怀孕年龄可能会受到与姐妹、母亲和父亲以及与不熟悉的雄性沙鼠的互动的影响。 (C) 2001 年动物行为研究协会。
We examined social influences on age at first reproduction in female members of 240 litters of Mongolian gerbils, Meriones unguiculatus. The results indicated that: (1) sisters inhibit one another's reproductive development, although this mutual inhibition is more strongly expressed in the presence than in the absence of an older, reproductively active female, (2) either sexual incompatibility develops between male gerbils and females that they help to rear, or female gerbils need to be exposed to strange males in order for their reproductive development to proceed to sexual maturity, (3) exposure of adult males to young females increases the males' subsequent latency to impregnate females other than those to which the males were exposed. Taken together the results suggest that age at first impregnation of female Mongolian gerbils living in family groups can be influenced by interactions with their sisters, dam and father, as well as with unfamiliar males.
