Abstract The 'centre–periphery hypothesis'(CPH) is a long‐standing postulate in ecology
that states that genetic variation and demographic performance of a species decrease from …

The distribution of genetic diversity within and among populations in relation to species'
geographic ranges is important to understanding processes of evolution, speciation, and …

We are experiencing climate warming that is likely to affect all regions worldwide, although
in a different manner, when its consequences (eg increase of temperature, lower …

Introduction With its distinctive evolutionary rate and inheritance patterns separate from the
nuclear genome, mitochondrial genome analysis has become a prominent focus of current …

Evaluating the contributions of geographic distance and environmental heterogeneity to the
genetic divergence can inform the demographic history and responses to environmental …

The genetic variation across a species' range is an important factor in speciation and
