Mitochondrial DNA (mtDNA) was used to characterize patterns of geographic variation among white-tailed deer (Odocoileus virginianus) populations in the southeastern United States. Fifteen restriction enzymes were employed to survey and map 99 restriction sites in 142 deer from 18 localities in five southeastern states. Phylogenetic analysis revealed three primary groups of haplotypes: (1) southern Florida and the Florida Keys, (2) the remainder of peninsular Florida northward to South Carolina, and (3) the Florida panhandle westward to Mississippi. Geographical heterogeneity in haplotype frequencies suggests that stochastic lineage sorting or isolation by distance are not important determinates of mtDNA differentiation among deer populations. The pattern of mtDNA variation in white-tailed deer is concordant spatially with those observed in unrelated taxa suggesting the common influence of historical biogeographic events. The data (1) support previous hypotheses that relate contemporary patterns of intraspecific phylogeography in northern Florida to the physiogeographic history of the region; and (2) suggest that genetic differentiation in southern Florida may be attributable to episodes of Pleistocene dispersal. Despite potentially high vagility and human intervention, ecological and demographic characteristics of deer have effectively preserved the historical pattern of intraspecific mtDNA differentiation.
线粒体DNA（mtDNA）被用于刻画美国东南部白尾鹿（弗吉尼亚鹿）种群间的地理变异模式。使用了15种限制性内切酶对来自美国东南部五个州18个地点的142头鹿的99个限制性位点进行了检测和图谱绘制。系统发育分析揭示了三个主要的单倍型组：（1）佛罗里达州南部和佛罗里达群岛，（2）佛罗里达半岛其余地区向北至南卡罗来纳州，以及（3）佛罗里达狭长地带向西至密西西比州。单倍型频率的地理异质性表明，随机谱系分选或距离隔离并非鹿种群间mtDNA分化的重要决定因素。白尾鹿的mtDNA变异模式在空间上与在不相关分类群中观察到的模式一致，这表明历史生物地理事件具有共同影响。这些数据（1）支持了先前的假设，即佛罗里达州北部当代种内系统地理学模式与该地区的自然地理历史有关；（2）表明佛罗里达州南部的遗传分化可能归因于更新世的扩散事件。尽管鹿具有潜在的高迁移性和人类干预，但鹿的生态和种群特征有效地保留了种内mtDNA分化的历史模式。
