Change Law of Population Reproductive Parameters in Different Age Groups of Apodemus agrarius during 2006 ～ 2010 in Yuqing County
摘要
Abstract
In order to further find out the change law of the population reproductive parameters in different age groups of Apodemus agrarius, the samples of this mouse were collected and surveyed by using night trapping method, and total 701 heads of Apodemus agrarius (female 327, male 374) were captured in Yuqing county of Guizhou province during 2006 ~ 2010. The analysis results showed that the total population sex ratio of Apodemus agrarius was 0. 87, and there was difference in sex ratio among different age groups. Sub -adult group, adult group I, adult group II and old group all could participate in the reproduction, and there was significant difference in reproductive capacity among different age groups. With the growth of population age, the pregnancy rate, littering size, reproductive index and descent rate of testicle increased, the adult group I, adult group II and old group were the main reproductive populations, their average pregnancy rate was 43. 01% , average littering size was 5. 11 heads, average reproductive index was 0.9298, and average descent rate of testicle was 95.44% , these parameters were significantly higher than the average value of the totality.关键词
