| 摘 要： | 为进一步了解横断山区小型哺乳动物的能量代谢对策,本文主要研究了横断山的外来物种——高山姬鼠(Apodemus chevrieri)持续冷暴露28d的能量变化。结果表明,随着冷驯化时间延长,体重和体温降低;摄入能、消化能和可代谢能增加,至21d后这3项指标又下降;BMR和NST增加,并且28d后它们分别是对照组的187.19%和155.97%;(NST-BMR)/BMR比值7d时增加到1.02,21d后下降至0.53,并保持稳定。因此,在持续冷暴露下,高山姬鼠采取适当降低体重和体温、增加能量摄入、增加BMR和NST产热等途径来维持能量代谢平衡,但是NST在产热中的作用逐渐降低。这种能量模式很可能代表了一种外来小型啮齿动物对于在横断山生存独特的能量适应策略。

| Abstract: | Apodemus chevrieri is an exotic species inhabiting Hengduan Mountains.In order to study its adaptive energy strategies under low temperature of the wood mice,we measured energy budge,BMR and NST during cold exposure for 28 days.During cold exposure,its body mass and temperature decreased gradually,while energy intake,digested energy and metabolizable energy intake increased gradually and achieved the highest value after 21 days.BMR and NST increased and reached to 187.19%,155.97% respectively of the control... |
