A new approach is introduced for the analysis of dispersal from the geographic distributions of mtDNA lineages. The method is based on the expected spatial distributions of lineages arising under a multigeneration random walk process. Unlike previous methods based on the predicted equilibria between genetic drift and gene flow, this approach is appropriate for non-equilibrium conditions, and yields an estimate of dispersal distance rather than dispersal rate. The theoretical basis for this method is examined, and an analysis of mtDNA restriction site data for Peromyscus maniculatus is presented as an example of how this approach can be applied to empirical data.
本文介绍了一种基于线粒体DNA谱系地理分布来分析扩散的新方法。该方法基于多代随机游走过程中谱系的预期空间分布。与以往基于遗传漂变和基因流之间预测平衡的方法不同，此方法适用于非平衡条件，且能得出扩散距离的估计值而非扩散速率。本文探讨了该方法的理论基础，并以鹿鼠线粒体DNA限制性酶切位点数据为例，展示了如何将此方法应用于实证数据。
