| 摘 要： | 为探讨短期持续限食对树麻雀(Passer monanus)体重和基础代谢率的影响,及其生理适应的调节机制。以正常饲喂树麻雀为对照组(0D组,D为饥饿天数),以进食量相同和持续限食时间不同的4组(1D、3D、5D和7D)树麻雀为研究对象进行限食驯养。结果显示,体重与个体BMR间存在极显著的线性关系(r=0.512,P=0.001);5组树麻雀单位体重的基础代谢率(BMR)差异不显著,5D和7D组树麻雀的个体BMR组间差异显著(P0.05);树麻雀的体重驯养前后变化为对照组增加而4个实验组降低,驯养后,1D和7D组与对照组相比体重降低分别为显著(P0.05)和极显著(P0.01),3D和5D组相对于1D、7D组出现小幅度的上调,1～7d持续限食树麻雀的体重出现降升降的趋势。结论是:当摄食量不足时,消耗体内的能量储备和降低个体的基础能耗对缓解短期持续限食的生存压力有利,但个体适合度随之降低。体内能量储备和个体基础能耗的相应增加是树麻雀应对饥饿环境的关键,也是其重要的生存策略之一。

| Abstract: | The present paper deals with the effect of short-term continuing food restriction on Tree Sparrows' (Passer montanus) body weight and BMR (basal metabolic rate) as well as their physiological adjusting mechanism. The Tree Sparrows fed regularly were selected to be the control group (0D,D for day) and four groups of sparrows with same food-intake but different hunger hours (1D,3D,5D and 7D) to be the objects of study and acclimation. The results shows that there exists marked linear relationship between the ... |
