Introgressive hybridization and the evolutionary history of the herring gull complex revealed by mitochondrial and nuclear DNA.

ABSTRACT:

Background

Based on extensive mitochondrial DNA (mtDNA) sequence data, we previously showed that the model of speciation among species of herring gull (Larus argentatus) complex was not that of a ring species, but most likely due more complex speciation scenario's. We also found that two species, herring gull and glaucous gull (L. hyperboreus) displayed an unexpected biphyletic distribution of their mtDNA haplotypes. It was evident that mtDNA sequence data alone were far from sufficient to obtain a more accurate and detailed insight into the demographic processes that underlie speciation of this complex, and that extensive autosomal genetic analysis was warranted.

Results

For this reason, the present study focuses on the reconstruction of the phylogeographic history of a lim
