摘要
实验测定了横断山的大绒鼠、高山姬鼠、中华姬鼠和中缅树鼩的基础代谢率。结果表明:大绒鼠、高山姬鼠、中华姬鼠和中缅树鼩的基础代谢率分别为1.92±0.1 ml O2/g.h,2.7±0.5 ml O2/g.h,2.97±0.6 ml O2/g.h,1.38±0.07 ml O2/g.h。通过四种小型哺乳动物体重和基础代谢率的比较统计分析后表明它们在横断山环境中出现了趋同适应。
The basal metabolic rate(BMR) were measured using AD ML870 open respirometer in Eothenomys miletus,Apodemus chevrieri,Apodemus draco and Tupaia belangeri. Using phylogenetically independent contrasts(PIC) and conventional statistics to analyze. Basal metabolic rates for E. miletus,A, chevrieri,A. draco and T. belangeri were 1.92 ±0.1 ml O2/g. h , 2.7 ±0.5 ml O2/g. h,2.97 ±0.6 ml O2/g. h and 1. 38 ± 0.07 ml O2/g. h, respectively. The results may reflect that four mammals in Hengduan mountains region appeared co - evolution
