| 中文摘要: |
| 研究了内蒙古草原布氏田鼠(Lasiopodomys brandtii)和长爪沙鼠(Meriones unguiculatus)的体重、身体脂肪、水分含量及身体热值等指标的季节变化。2种动物的体重都是在春季最高,布氏田鼠的体重具显著的季节变化,长爪沙鼠的鲜重具季节变化,但干重则基本维持恒定。2种动物的脂肪含量和身体热值都在秋季最高,但体水含量在夏季最高。体重的变化受身体脂肪和体水含量等因素共同的影响,而2种动物的身体脂肪和水分含量受环境温度及食物的因素影响较大,所以2种动物体重的季节变化格局有所不同。 |
| 英文摘要: |
| Seasonal variations in body weight and composition of body fat and water, as well as energy contents were measured in field Brandt's Voles (Lasiopodomys brandtii) and Mongolian Gerbils (Meriones unguiculatus). Both species had the highest body weights in spring, highest fat and energy contents in autumn, and highest water contents in summer. However, patterns of seasonal variations in body weights are different between Voles and Gerbils. Body weight variations were affected by both water and fat contents, which might be influenced by ambient temperature and food quality. |
