项目摘要

The house musk shrew, Suncus murinus, is the only laboratory animal that has been successfully domesticated among species of Insectivores. The present study examined its behavior traits and formulated its keeping system for use in behavioral studies. The following results were obtained.(1) Daily activity rhythm : The rhythms were obtained for body temperature and locomotor activity. There were observed a unique drop in body temperature which was synchronized with disappearance of locomotion. It occurred once a day in several successive days. This finding leads us to discuss its relation with the phenomenon of "daily torper".(2) Drive : Drive force was measured as a function of hours of water deprivation. Shrews showed a specific mode of drive change which was different from rats and mice. It should be further examined in relation to basal level of metabolism and inhibitive system of brain function.(3) Behavioral effect of domestication : Domestication which was started in 1993 with nearly 40 wild animals has so far been successfully proceeded in our laboratory. However, no significant effect of domestication was found with early and mating behaviors for the first 15 generations.(4) Keeping and breeding in artificial environment : Standard procedure and environment for keeping and breeding were formulated for both domesticated and wild shrews, in spite of small litter size and frequent occurrence of infanticide.(5) Ecological information on wild populations : Ecological condition and behavioral information were collected from informants in three islands of Okinawa district. In parallel to the reduction in size of population, amount of information has been decreased.A report including both of the present and previously published results was edited.

麝香鼩（Suncus murinus）是食虫动物中唯一被成功驯化的实验动物。本研究检查了其行为特征并制定了其饲养系统以用于行为研究。获得以下结果。 (1)日常活动节律：获得体温和运动活动的节律。观察到体温独特下降，与运动消失同步。连续几天每天都会发生一次。这一发现引导我们讨论它与“每日 torper”现象的关系。(2) 驱动力：驱动力是根据缺水时间的函数来测量的。鼩鼱表现出与大鼠和小鼠不同的特定驱动力变化模式。还需进一步考察基础代谢水平和脑功能抑制系统的关系。 (3)驯化的行为效应：本实验室自1993年开始对近40只野生动物进行驯化，至今已成功进行。然而，驯化对前15代的早期和交配行为没有显着影响。（4）人工环境饲养和繁殖：为家养和野生鼩鼱制定了标准的饲养和繁殖程序和环境，尽管(5)野生种群生态信息：从冲绳地区三个岛屿的受访者那里收集生态状况和行为信息。在人口规模减少的同时，信息量也减少了。编辑了一份包含当前和以前发表的结果的报告。
