Research progress on population genetic heterogeneity

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.
