Abstract: To investigate the biological properties of Mus musculus, snap-trapping was used in the middle ten-days of every month from April to October during 1991 to 1996 in different habitats of Ordos sandland. The results showed that Mus musculus was uncommon species which accounts for only 2% of the total rodent number in the area. The optimum habitats of Mus musculus were low-lying lands among dunes, while wind-drifed dunes were the most unsuitable habitats. A total number of 162 specimens were collected and dissected. All the specimens were divided into four age groups based on their body weight excluding viscera. The body weight excluding viscera was ≤6.9g for group Ⅰ (juveniles), 7.0~8.9g for group Ⅱ (subadults), 9.0~12.9g for group Ⅲ(adults) and ≥13.0g for group Ⅳ(old ages). Their breeding period was from March to October and litter size was 7.08±1.90.
摘要: 目的:观察鄂尔多斯沙地草场中小家鼠的栖息环境、体尺、繁殖特性及年龄组划分。方法:1991~1996年每年4~10月的每月中旬在沙地草场的6种生境内利用直线夹日法进行调查,捕获的鼠进行外形度量、解剖、称量胴体重。结果:小家鼠在当地属少见种(6年捕到162只,占捕获总数的2%)。该鼠喜欢在沙地草场的丘间滩地栖息,其次为半固定沙地和农田,流动沙地最不宜栖息。依据胴体重将该鼠种群划分为4个年龄组:≤6.9g为幼年组,7.0~8.9g为亚成年组,9.0~12.9g为成年组,≥13.0g为老年组。3~10月为该鼠繁殖期;老年组参加繁殖的个体占该年龄组总数的81.81%,成年组占78.17%,亚成年组占50%。平均胎仔数为7.08±1.90个。结论:本地区小家鼠较南方同种类的个体小,性成熟晚,繁殖期短,但胎仔数多。
