摘要
小毛足鼠饲喂试验结果以及颊囊食物统计结果表明,该鼠在饲喂条件下食物资源利用谱相对较宽,但在野外条件下食物资源的利用主要以植物种子为主;并结合具体情况探讨了造成野外条件下该鼠食物资源利用范围趋于特化的原因.估算了小毛足鼠的采食效率为0.076%~0.14%.在以上研究基础上。
By carrying the feeding experiment and the analysis of cheek pouch contents for P.roborovskii, we found that the desert hamster eats many kinds of food including plant body and seeds under the first circumstances while does only seeds under the second circumstances.Namely,the feeding habitats of the rat have become narrow relatively in the field environments.Certainly,the reason causing the consequence have been discussed further.On the other hand,based on the food consumption and the results summed up by the predecessors,the food searching rate of the rat preliminary estimated is 0.017% ̄0.14%.Finally,we approach the subject for the harm of the Phodopus roborovskii.
