摘要:

生境破碎和种群隔离在野生动物管理中倍受关注,种群遗传异质性结合种群统计学和生境资料,可解释和推测种群经历的种群统计学随机事件,分析异质生境对种群遗传组成的影响,估计地理种群之间的基因交流和遗传分化,对物种保护具有重要指导意义。

Abstract

Habitat fragmentation and population isolation are of increasing concern in the management of wildlife resources. With the information of population genetic heterozygosity, incorporating population demorgraphic data and status of the habitat in which the population lived, we can analyse the genetic effect of demorgraphic stochasity on local populations, the effect of habitat heterogeneity   on population genetic structure, and estimate gene flow among geographic populations, the level of population differentiation. It is of great value in the management practice of endangered species, planning for population  restoration and designing of nature reserve.
