摘要: 本文使用自制的陆生动物温度选择仪,对长爪沙鼠和黑线仓鼠的温度选择进行了比较,结果表明,长爪沙鼠的选择温度(29.06±0.62℃)较黑线仓鼠(26.65±0.64℃)高。这种差异可能与两种鼠的栖息环境及昼夜节律的不同有关。

Abstract: This paper reports the temperature preferences about Meriones unguiculatus and Cricetulus barabensis and their comparison between the two rodents.The temperature preference was measured by the automatic recording thermal gradient apparatus.The experiment shows that temperature preference of Meriones unguiculatus is 29.06 ± 0.62℃ and that of Cricetulus barabensis is 26.65±0.64℃. Maybe it is related to the difference of their circadian activity rhythm or the difference of their habitat.The size of the animal's body is an important factor which is related to temperature preference. In the two species, the bigger the body size, the lower the temperature preference is.
