| 摘 要： | 对《华南虎谱系》307 只登录个体的统计表明, 其圈养的历史有46 年。在人工繁殖的38 年中产122 胎287仔。现存圈养华南虎分散在全国22 家单位, 有57 只个体, 性比M∶F = 1185 , 能成功繁殖后代的个体仅5 只(只占818 %) , 是一个衰退的种群。通过SPARKS 和GENES 软件分析发现: 从1977 年开始, 圈养种群的基因多样性便逐渐下降而近交系数却不断增加。

| Abstract: | From 1963-2000,a total of 307 South China tigers( Panthera tigris amoyensis ) were recorded in the regional studbook. During 38 years of breeding in captivity,a total of 287 cubs were born with 122 litters in Chinese zoos or parks. Our analyes using SPARKS and GENES softwares indicated that the gene diversity of the South China tigers has been decreased while the inbreeding coefficient has been increased since 1977.The captive population consists of 57 individuals descended from 6 founders with a total of 37 males and 20 females(M/F = 1.85). Current captive group is distributed in 22 zoos or parks,with a high risk of extinction. |
