Past hybridization between two East Asian long-tailed tits (Aegithalos bonvaloti and A. fuliginosus).

ABSTRACT:

Introduction

Incomplete lineage sorting and hybridization are two major nonexclusive causes of haplotype sharing between species. Distinguishing between these two processes is notoriously difficult as they can generate similar genetic signatures. Previous studies revealed that the mitochondrial DNA (mtDNA) differentiation between two East Asian long-tailed tits (Aegithalos bonvaloti and A. fuliginosus) was extremely low, even lower than intraspecific differentiation in some other long-tailed tits. Using a combination of multilocus and coalescent analyses, we explored the causes of the anomalous lack of mtDNA differentiation between the two species.

Results

The mtDNA divergence between the two species was shallow, while the nuclear DNA (nuDNA) divergence was considerably deep
