摘要: 本文报告1990年1~12月对上海郊区九县三种生境大麝鼩的生态学调查结果。观察到各县间大麝鼩捕获率差异颇大,最低为0.83%,最高为6.21%;三种生境以宅周捕获率最高,室内厨房次之,大田最低;全年有春、秋两个数量高峰,以秋峰(10月)为高;雌雄性比为1.36∶1;剖析525只雌体,怀孕率为33.71%。结果表明,12月份为繁殖休止期,3~4月怀孕率为54.22~58.33%,此后降至35~40%,8月出现第二个怀孕峰值,达60.61%,11月份迅速降到7.14%。分析495只体重与怀孕率的关系,发现随体重增加,怀孕率相应提高,二者呈正相关(r=0.9689)。剖析707只完整的大麝鼩胃内容物,发现主食谷物、昆虫和环节动物,少食绿色植物和种子;因月份不同,胃内容物出现频次有所差异。

Abstract: Ecological investigations of Large Whitetoothed Shrew in January to December 1990 in Shanghai rural. The result was as follow: The population density of Large White-toothed Shrew may be drawn using a curve whth a peak in Oct. There are two breeding peaks ia February-March and August. There were a interval of breeding disapause in December. By dissecting 707 shrew stomachs, it was found that most of the food were insect, annelid and rice. also included a few plant and seeds, The differences between food and every month was found.Analysis 495 Shrews weight and the rate pregnancy, the result was found that they reveal positive correlation (P≤0.01)
