Spatial Distribution Patterns of Genetic Variation in Four Rhodiola Species: Testing the Centre‐Periphery Hypothesis

open access: yesDiversity and Distributions, Volume 31, Issue 10, October 2025.
ABSTRACT Aim Understanding the spatial distribution of genetic variation is crucial for conservation biogeography. The centre‐periphery hypothesis (CPH) posits that central populations exhibit higher genetic diversity and lower differentiation. However, it remains unclear how species centre definitions and associated factors influence genetic variation
