Abstract/OtherAbstract:
Phylogeographic analyses have mostly been based on single-gene genealogies but it is unclear how conclusions from such studies depend on the choice of gene markers. We conducted a nested geographical clade analysis [A.R. Templeton, E. Routman and C.A. Phillips (1995) Genetics 140: 767-782] based on nuclear rDNA internal transcribed spacer region 2 (ITS2) sequences in the Timarcha goettingensis species complex (Coleoptera, Chrysomelidae), and compared the inferences with an updated version of previously published results using mitochondrial cytochrome oxidase II (COIl) sequences. Inferences from ITS2 suggest that patterns of marker distribution are mostly explained by restricted gene flow with isolation by distance. In contrast, COII revealed a history of geographical structure resulting from episodic population contiguous-range expansions. Both markers also show different genealogical patterns, which are associated to the effects of genetic introgression in a putative hybrid zone between two major lineages in the complex. Altogether, these differences are attributed to distinct population and/or evolutionary dynamics of the markers, and offer a more accurate phylogeographic description for the T. goettingensis complex.
