大仓鼠肥满度的研究

本文依公式K=100W/L~3计算了大仓鼠肥满度。统计结果表明,雌性肥满度大于雄性肥满度。肥满度随年龄增长而减小。不同作物类型样地中大仓鼠的肥满度变化不明显。不同季节肥满度有一定的变化,主要与繁殖和气候有关。肥满度与种群密度之间不存在明显的对应关系。

STUDIES ON THE RELATIVE FATNESS OF GREATER LONG-TAILED HAMSTER

The relative fatness of greater long-tailed hamster (Cricetulus triton) was calculated by the formula K = 100/L3, where K represents the relative fatness, W the body weight in gram, L the length of head and body in cm. Statistical results show that the relative fatness of females was higher than that of males. The relative fatnesses were becoming lesser as the age was growing up. The relative fatness didn' t change evidently in different crop fields, but it changed evidently in different seasons, which was mainly influenced by climates and reproductions. Statistical results also show that there was not corresponding relation between the relative fatness and the population density.
