Spatial Patterns of Intraspecific Genetic Diversity Follow no General Rule Across Climatic and Geographic Gradients.

Molecular ecology - 1 Mar 2026

Abstract excerpt

Intraspecific genetic diversity (ISD) underpins key eco-evolutionary processes, yet its spatial distribution across species' ranges remains poorly understood at broad scales. Combining mitochondrial sequence alignments, species distribution models and comparative analyses, we tested whether populations closer to current niche optima exhibit higher ISD-a prediction derived from the central-marginal paradigm. With...
