Article Synopsis
  • This study explores the population divergence of the western fence lizard (Sceloporus occidentalis) across Western North America, focusing on how geographical features and climate impact their reproductive isolation.
  • Researchers utilized double digest RAD sequencing to analyze population structure, phylogeny, and demographic patterns, discovering that gene flow exists despite regional divergence.
  • The concept of an "ephemeral ring species" is proposed, highlighting that unlike typical ring species, S. occidentalis shows high genetic diversity in both northern and southern populations due to different historical factors like secondary contact and long-term habitat stability.

The distribution of mean heterozygosities under an infinite allele model with constant mutation rate was examined through simulation studies. It was found that, although the variance of the distribution decreases with increasing numbers of loci examined as expected, the shape of the distribution may remain skewed or bimodal. The distribution becomes symmetrical for increasing mean heterozygosity levels and numbers of loci.
