Deforestation and thinning are human activities that can destabilize the forest ecological system and, consequently, impact significantly on habitat and behavior of forest-dwelling animals. This hypothesis was tested in Yugong in the Mount Taihangshan area by comparing the tracks of tagged seeds of Armeniaca sibirica. in sites of unthinned and thinned forests. Our results showed that: (i) the diversity of vegetation and rodents drastically reduced in sites with thinned forests, compared to unthinned sites; (ii) the amount of both removed and scatter-hoarded seeds significantly declined in sites with thinned forests, compared with the unthinned sites; (iii) there was no significant difference observed in the distance of seed dispersal between the thinned and unthinned areas; and (iv) the thinning did not show a significant change to the model of cache size. These results suggested that the thinning of forests negatively influenced the species richness and food-hoarding behavior of rodents. In addition, the results indicated that the weakened scattered-hoarding might be disadvantageous to seedling recruitment and forest restoration.
森林砍伐和疏伐是人类活动，会破坏森林生态系统的稳定性，进而对栖息在森林中的动物的栖息地和行为产生重大影响。通过比较太行山区愚公地区未疏伐和已疏伐森林中郁李种子标记轨迹，对这一假设进行了验证。我们的结果表明：（i）与未疏伐的地点相比，已疏伐森林地点的植被和啮齿动物多样性大幅降低；（ii）与未疏伐的地点相比，已疏伐森林地点被移除和分散贮藏的种子数量均显著下降；（iii）疏伐区和未疏伐区之间种子传播距离未观察到显著差异；（iv）疏伐对贮藏大小模型未显示出显著变化。这些结果表明，森林疏伐对啮齿动物的物种丰富度和食物贮藏行为产生了负面影响。此外，结果表明，分散贮藏能力的减弱可能不利于幼苗更新和森林恢复。
