摘要
在洞庭湖区域,社鼠(Niviventer confucianus)主要栖息在山区和丘陵区的林地,山边农田与农房也有少量栖息.社鼠体型中等,体重最大的仅100 g左右,尾长大于或等于体长.雌雄体之间的外形体尺指标基本一致,不存在性二型现象.随着年龄的增长,体重的增加,胴体重、体长、尾长、耳长和后足长均有显著增长,其中,胴体重、体长和尾长随体重增加一直保持相对快速的增长趋势,而成年后的耳长与后足长增长缓慢,变化相对较小.
The sulphur bellied rat(Niviventer confucianus) in Dongting Lake region inhabited mostly inside bush or forest of the mountain and hill. The animals also could be caught in the farmland beside bush and sometimes it might even be found in farmhouse. The animal had middle somatotype among rodentia and their body length was shorter than its tail length. Most body measureracnts between males and females of each age class have no significant differences, which showed that the animal had no sexual dimorphism in exterior morphology, It's body weight excluding viscera, body length, the tail length, ear length and crus length of the animal kept increasing with the growth of the animal. However, when growing up, the growth of the animal's ear and crus turned slower.
