本文报道了1987~1995年贵州余庆县黑线姬鼠的种群繁殖特征。共解剖标本3964只(雌性1966只,雌性1998只)。主要繁殖期在3~11月,研究期间的月平均怀孕率46.83%;平均胎仔数为5.48±0.06只;繁殖指数为1.28±0.07;每年4~5月和8~9月为两次妊娠高峰。雄鼠睾丸下降率和雌鼠怀孕率有同步变动趋势。不同年龄组之间繁殖力存在显著性差异。

Two populations of plateau zokor one was removed part and another was not in alpine meadow were studied by comparison in Haibei, Qinghai province from May 1995 to October 1996. The natural population density was significantly higher than that of remnants. 470 zokors were captured from two populations in 1996. There was significant difference in age structure between two population in May ( X 2 =9 97, P <0 05), moreover, strongly significant difference in July and October, respectively ( X 2 =15 ...

Two populations of plateau zokor one was removed part and another was not in alpine meadow were studied by comparison in Haibei, Qinghai province from May 1995 to October 1996. The natural population density was significantly higher than that of remnants. 470 zokors were captured from two populations in 1996. There was significant difference in age structure between two population in May ( X 2 =9 97, P <0 05), moreover, strongly significant difference in July and October, respectively ( X 2 =15 134, X 2 =15 612 , P <0 01). Adult I of remnant in May occupied 53 45% was strongly higher than that of naturals that occupied 29 69%. However, Adult II of remnant only occupied 34 48% was lower than that of naturals (48 44%) in same period. Age classes of natural population were relatively stable in different season, but remnants were not. The total of Juvenile and Subadult in remnant occupied 35 06% was higher than that in natural (22 00%) in July. There was significant difference in age structure between two populations in October. Adult of remnant occupied 51 35% was significantly different with naturals (23 01%), Olders and Oldests only occupied 9 62% was significant lower than that of naturals (23 08%). The body length and weight in all age classes were not significantly different. But, the body weight of male showed significantly positive correlation with age class. The female pregnancy rate of adult I of remnant population was higher than that of naturals, the litter size of remnant population was 3 32,that of naturals was 2 85. The significant difference was not found.

捕杀高原鼢鼠后,残鼠种群与自然种群年龄结构相比较,5月差异性显著(X2=997,P<005);7月和10月差异极显著(X2=15134,X2=15612,P<001)。5月,残鼠种群成年Ⅰ组占最大比例(5345%);自然种群成年Ⅱ组占最大比例(4844%)。7月,残鼠种群幼年组和亚成年组所占比例之和(3506%)明显高于自然种群(2200%)(P<005)。10月,残鼠种群近老年组和老年组所占比例之和(962%)明显低于自然种群(2308%)(P<005)。残鼠种群成年Ⅰ组雌鼠怀孕率(8462%)明显高于自然种群(5833%)(P<005);平均胎仔数(332)也高于自然种群(285),但差异不显著(P>005)。

The reproduction of population of Apodemus chevieri in Dafang county of Guizhou province was investigated during 1996~1998. A total of 520 specimens were collected and dissected, among which 264 were female and 256 male. In main propagating season, the mean pregnancy rate, litter size and reproductive index were 18 .62%, 6. 03 and 0. 6846, respectively. The fluctuations of the rate of testis in serotum were identical with the rate of female pregnancy.
