Shared response to changes in drainage basin: Phylogeography of the Yunnan small narrow-mouthed frog, Glyphoglossus yunnanensis (Anura: Microhylidae).

Lineage division conformed to the hypothesis of drainage system evolution, that is, the phylogeographic pattern of G. yunnanensis was shaped by historical drainage patterns. Concordance in phylogeographic patterns may suggest a shared response to common hydrogeological history and also might indicate that there was more contribution of the drainage history than ecological or life-history traits in structuring genetic variation between these two disparate codistributed taxa G. yunnanensis and N. yunnanensis.
