Overview

Phylogenetic analysis reveals endemic Japanese rock ptarmigan populations, suggesting conservation importance.

Key Points

  • The research aims to clarify the phylogenetic origin and genetic diversity of the rock ptarmigan in Japan.
  • Conducted mitochondrial genome analysis using museum specimens over 100 years old
  • Analyzed control region and ND5 for genetic diversity
  • Performed network analysis of control regions from 209 individuals globally
  • Determined complete mitochondrial genomes for 18 individuals
  • Japanese populations found to be endemic with no regional differentiation
  • Divergence estimated to have occurred 80,000–120,000 years ago
