中文摘要：

对栖息于滇中高原边缘地区的小型哺乳动物中缅树鼩夏季的代谢率、热传导、体温和蒸发失水等生理生态特征随环境温度的变化进行了测定,结果表明：中缅树鼩在夏季体温相对较高,受环境温度的影响较大;蒸发失水与环境温度显著正相关,在热中性区内基本维持相对稳定的水平,为2.82mgH2O/g·h;在37.5℃时达到高峰值,为3.88mgH2O/g·h,蒸发失水在体温调节中起着重要作用。结合同域分布的其他物种的生理生态学特征,提出中缅树鼩在热能代谢、体温调节及蒸发失水方面具有热带小型哺乳动物的特征,同时,又显示出某些适应于亚热带高原气候的特点。

英文摘要：

Evaporative water loss （ EWL） and energy metabolism were measured at different temperatures in tree shrews （ Tupaia belangeri） from the Kunming area of Yunnan Province. The thermal neutral zone （ TNZ） of T. belangeri was 3035 ℃,and the average EWL was 2. 82 mg H2O/g·h within the TNZ. EWL in T. belangeri increased as the temperature increased,the maximal EWL was 3. 878 mg H2O/g·h at 37. 5 ℃. EWL plays an important role in the regulation of body temperature. Compared with the ecophysiological characteristics of sympatric species in the same area,we concluded that T. belangeri has the typical characteristics of tropical small mammals in metabolism,body temperature regulation and EWL, but it shows some ecophysiological characteristics adapted to the subtropical plateau climate.
