Heteropatric differentiation is a mode of speciation with gene flow in which divergence occurs between lineages that are in sympatry and allopatry at different times during cyclic spatial movements. Empirical evidence suggests that heteropatric differentiation may prove to be common among seasonally migratory organisms. We examined genetic differentiation between the sedentary Aleutian Islands population of green-winged teal (Anas crecca nimia) and its close migratory relative, the Eurasian, or Old World (OW), Anas c. crecca population, a portion of which passes through the range of nimia during its seasonal migrations. We also examined its relationship with the parapatric North American, New World (NW), A. c. carolinensis population. Sequence data from eight nuclear introns and the mtDNA control region showed that the nimia-crecca divergence occurred much more recently than the deeper crecca-carolinensis split (~83,000 y vs. ~1.1 My). Despite considerable spatial overlap between crecca and nimia during ... : CHD1Z.nexNEXUS file containing 175 resolved alleles from intron 19 of the chromo-helicase DNA binding (CHD1Z) gene sampled from 105 Common (Green-winged) Teal (Anas crecca). Populations (OW, Old World; NW, New World; Attu, Aleutian Islands; Shemya, Aleutian Islands; Adak, Aleutian Islands; Ugamak, Aleutian Islands) are defined within the file. Note that CHD1Z is located on the Z-chromosome, and therefore, females only have a single copy.ALTE-CHD1Z.nexCRYAB.nexNEXUS file containing 202 resolved alleles from intron 1 of the alpha-B crystallin (CRYAB) gene sampled from 101 Common (Green-winged) Teal (Anas crecca).
