居住在下加利福尼亚半岛沙漠的许多物种在半岛中部表现出一种共同的地理断裂，以前的研究人员将这种共同的模式归因于一个单一的替代事件，即半岛中部的海道。然而，以前的研究没有明确考虑到固有的随机性与基因树聚结的物种之前的时间假定的半岛中部分歧。我们使用贝叶斯分析的分层模型来测试同时vicariance跨共同分布的姐妹血统共享一个宗谱在半岛中部的休息。这种贝叶斯方法是优于传统的系统发育的解释，因为它考虑了与合并和突变过程，以及影响基因树合并模式的基因谱系的人口统计差异的遗传变异。线粒体DNA数据从六个小型哺乳动物和六个有鳞爬行动物不支持的看法，一个共同的替代历史之间的血统表现出南北分歧在半岛中部，而不是支持两个事件差异结构在这一地区的遗传多样性。
Many species inhabiting the Peninsular Desert of Baja California demonstrate a phylogeographic break at the mid-peninsula, and previous researchers have attributed this shared pattern to a single vicariant event, a mid-peninsular seaway. However, previous studies have not explicitly considered the inherent stochasticity associated with the gene-tree coalescence for species preceding the time of the putative mid-peninsular divergence. We use a Bayesian analysis of a hierarchical model to test for simultaneous vicariance across co-distributed sister lineages sharing a genealogical break at the mid-peninsula. This Bayesian method is advantageous over traditional phylogenetic interpretations of biogeography because it considers the genetic variance associated with the coalescent and mutational processes, as well as the among-lineage demographic differences that affect gene-tree coalescent patterns. Mitochondrial DNA data from six small mammals and six squamate reptiles do not support the perception of a shared vicariant history among lineages exhibiting a north–south divergence at the mid-peninsula, and instead support two events differentially structuring genetic diversity in this region.
