To determine the role of the parental environment in the formation of species attachments in the meadow vole (Microtus pennsylvanicus), young of this species were fostered to either meadow vole parents (in-fostered young) or to prairie vole parents (M. ochrogaster; cross-fostered young). At 50 to 60 days of age, subjects were tested for social preference in an environment that simulated the conditions of a runway system. The testing design assessed the reaction of fostered animals to a novel species (M. pinetorum) as well as to the parental and biological species. The proportion of total test time spent near stimulus animals did not vary as a function of rearing condition. However, when compared to in-fostered controls, cross-fostered meadow voles displayed increased preference for prairie voles. Novelty did not appear to be a significant factor in test animal choice. These results suggest that in meadow voles, preference for the species of social partner is dependent on postnatal experience with parents.
为了确定亲代环境在草甸田鼠（Microtus pennsylvanicus）物种依恋形成中的作用，将该物种的幼崽寄养给草甸田鼠亲代（亲生寄养幼崽）或草原田鼠亲代（M. ochrogaster；交叉寄养幼崽）。在50至60日龄时，在模拟跑道系统条件的环境中测试实验对象的社会偏好。测试设计评估了寄养动物对新物种（M. pinetorum）以及对亲代和亲生物种的反应。在刺激动物附近花费的总测试时间比例并未因饲养条件而有所不同。然而，与亲生寄养对照相比，交叉寄养的草甸田鼠对草原田鼠表现出更高的偏好。新奇性似乎不是测试动物选择中的重要因素。这些结果表明，在草甸田鼠中，对社会伙伴物种的偏好取决于出生后与亲代的经历。
