贵州省针毛鼠肥满度的变化规律

通过对1984-2013年在贵州省余庆县、岑巩县、凯里市、雷山县稻田区和旱地耕作区采集的179只针毛鼠的肥满度进行分析,探讨其不同地区、生境、性别、年度、月份、季节、年龄间肥满度的变化规律。结果表明,针毛鼠肥满度变幅在1.56-4.98 g·cm-3之间,平均肥满度为(2.99±0.58)g·cm-3。不同地区之间以及稻田区、旱地耕作区之间肥满度差异不显著,雌、雄鼠肥满度差异不显著,不同年度间肥满度存在显著差异,月份、季节间差异不显著,不同年龄组肥满度有所不同,但差异不显著。

Dynamics of relative fatness of Niviventer fulvescens in Guizhou Province

In order to investigate the dynamics of relative fatness in different regions, habitats, sexes, years, months, seasons, age groups, the authors analyzed relative fatness of 179 Niviventer fulvescenz which were captured from paddy fields and dryland farming areas in Yuqing County, Cengong County, Kaili City and Leishan County, Guizhou Province from 1984 to 2013. The results showed that relative fatness of N.fulvescegs was between 1.56 g · cm^-3 and 4.98 g · cm^-3, （2.99 ±0.58） g · cm^-3 on average. There was no significant difference in relative fatness between different areas and between paddy field area and dry farming area and between female and male. The difference in relative fatness between different years was significant. There was no significant difference in relative fatness between different months and different seasons. There was a certain difference in relative fatness between different age groups, but it was not significant.
