【摘要】 <正> 黄毛鼠(Rattus losea)是我国长江以南分布极广的一种农林业重要害兽,也是南方恙虫病立克次体及钩端螺旋体的主要贮存宿主之一。林浩然等(1961)对黄毛鼠的某些生态研究中发现,该鼠在广东地区,秋冬季常有数只成鼠(6—7)同穴群居习性。1979—1980年,我们在浙江北部对黄毛鼠的生态作四季调查时,也发现此鼠于冬季有集群现象。但由于对黄毛鼠的生理生态还研究得很少,例如环境温度对黄毛鼠的影响怎样?聚群有何生理生态学方面的意义?因此本文试图着重探讨一下聚群与环境温度对黄毛鼠的能量代谢影响。更多还原

【Abstract】 1. The metabolism of oxygen consumption of Rattuft losea has negative correlation with body weight. The dominance of corelation is very significant. The oxygen consumption gradualy descends as the ambient temperature ascends (from 10℃ to 30℃). The oxygen consumption has seasonal variation. It is lower in winter than in summer.2. Animal crowding may reduce the loss of heat energy, and also decreas the consumption of food in winter. But Rattus losea Crowding long time, especially, when natural ambient temprature ascends after, would certainly lead animals decreasing the adaptive ability tp variation of ambient temprature.更多还原
