Understanding the evolutionary dynamics of genetic diversity is fundamental for species
conservation in the face of climate change, particularly in hyper-diverse biomes. Species in …

Range expansions—whether permanent or transient—strongly influence the distribution of
genetic variation in space. Monarch butterflies are best known for long‐distance seasonal …

The southeastern Nearctic is a biodiversity hotspot that is also rich in cryptic species.
Numerous hypotheses (eg, vicariance, local adaptation, and Pleistocene speciation in …

Abstract Aim The Mediterranean Basin is a global biodiversity hotspot and has one of the
longest histories of human–biota interactions. Islands host a large fraction of Mediterranean …

The effects of genetic introgression on species boundaries and how they affect species'
integrity and persistence over evolutionary time have received increased attention. The …

Accelerating climate change and habitat loss make it imperative that plans to conserve
biodiversity consider species' ability to adapt to changing environments. However, in biomes …

High‐throughput sequencing data have greatly improved our ability to understand the
processes that contribute to current biodiversity patterns. The “vanishing refuge” …

Comparative phylogeographic studies often support shared divergence times for co-
distributed species with similar life histories and habitat specializations. During the late …
