Recurrent hybridization shapes the diversification of Western Palearctic common toads (Bufo bufo complex).

Glacial cycles repeatedly fragmented temperate species into refugial populations, fostering divergence as a first stage towards speciation. Yet, interglacial expansions often reconnected these lineages, allowing gene flow to erode differentiation and reshape phylogeographic trajectories. We investigate these dynamics i...
