摘要: 镜像、影像等虚拟条件可能影响动物的觅食行为和活动时间分配。利用控制性围栏实验观察了同种个体实体、镜像及影像对ICR小鼠(Mus musculus)的觅食行为和活动时间分配的影响。发现实验鼠与实体接触时间显著高于与镜像、影像的接触时间;实体存在时,实验鼠显著增加了在低竞争风险区域贮藏食物量和巢外活动时间;影像存在时,实验鼠显著减少了巢外活动时间。结果提示ICR小鼠在实体、镜像、影像条件下表现出不同的觅食策略和活动时间分配,其觅食行为具有一定的可塑性。该结果可能为进一步研究ICR小鼠的行为及饲养管理提供一定参考。

Abstract: It is unknown how animals regulate their foraging behavior in presence of mirror image and video of conspecific individuals. Here, foraging behaviors and time-budgets of ICR mice (Mus musculus) were tested in presence of a conspecific individual, a mirror image, conspecific video or non-competitors (control) within indoor enclosures. ICR mice tended to move foods to the area with low competitive risks for hoarding in presence of conspecific individuals, whereas they spent more time touching and staying with a conspecific individual than with the mirror image or conspecific video. These results suggest that ICR mice adopt different strategies of foraging and time-budgets under different conditions.
