Description
Summary:Many species have Holarctic distributions that extend across Europe, Asia, and North America. Most genetics research on these species has examined only mitochondrial (mt) DNA, which has revealed wide variance in divergence between Old World (OW) and New World (NW) populations, ranging from shallow, unstructured genealogies to deeply divergent lineages. In this study, we sequenced 20 nuclear introns to test for concordant patterns of OW-NW differentiation between mtDNA and nuclear (nu) DNA for six lineages of Holarctic ducks (genus Anas). Genetic differentiation for both marker types varied widely among these lineages (idiosyncratic population histories), but mtDNA and nuDNA divergence within lineages was not significantly correlated. Moreover, compared to the association between mtDNA and nuDNA divergence observed among different species, OW-NW nuDNA differentiation was generally lower than mtDNA divergence, at least for lineages with deeply divergent mtDNA. Furthermore, coalescent estimates indicated ... : 6 Anas species mtDNA & 20 introns individual FASTA filesThis zipped folder contains 126 FASTA files, each containing aligned sequences (N = ~100 sequences) from one species (species pair) and one locus (6 species x 21 loci). The sequences are all introns only, and the gametic phases of alleles are resolved with >90% probability. Individual sequences are labeled "o" for Old World and "n" for New World.6 Anas species mtDNA & 20 loci individual FASTA files.zip6 Anas species 20 loci concatenated Nexus FilesThis zipped folder contains NEXUS files of 20 concatenated introns for each of 6 species (or species pair) of Anas ducks (~100 sequences per species). The sequences are all introns only, and the gametic phases of alleles are resolved with >90% probability. Individual sequences are labeled "o" for Old World and "n" for New World. Locus identification is provided at the end of each file.6 Anas species 20 loci STRUCTURE input filesThis zipped folder contains STRUCTURE input files containing ...
