臭鼩鼱生物学特性动态研究

Dynamic study on biological traits of Suncus murinus

于2008年3月至2009年2月,以夹夜法调查了湛江师范学院臭鼩鼱的生物学特性。结果显示,臭鼩鼱平均捕获率为15.40%,高峰期出现在8月。性别比为1.25∶1,年均怀孕率为32.41%,平均胎仔数为3.5。表明臭鼩鼱密度和种群结构受环境、气候和药物影响而改变,怀孕率也与气候密切相关。

From March 2008 to February 2009,we used Night trapping method to investigate the ecology of Suncus murinus in Zhanjiang Rormal University.The results showed that the means capture rate of Suncus murinus was 15.40%,the peak was in August.The amphoteric ratio was 1.25∶1.Whole year average pregnancy rate of Suncus murinus was 32.41%,the average enbryo was 3.5.Density and species proportion of Suncus murinus were influenced by some factors,such as environmental condition,climate and poison.Pregnancy rate of Suncus murinus was closely related to climate.
