Data from: A parapatric propensity for breeding precludes the completion of speciation in common teal (Anas crecca, sensu lato)

Speciation is a process in which genetic drift and selection cause divergence over tSpeciation is a process in which genetic drift and selection cause divergence over time. However, there is no rule dictating the time required for speciation, and even low levels of gene flow hinder divergence, so that taxa may be poised at the threshold of speciation for long periods of evolutionary time. We sequenced mitochondrial DNA (mtDNA) and eight nuclear introns (nuDNA) to...

Data from: Behavioral vs. molecular sources of conflict between nuclear and mitochondrial DNA: the role of male-biased dispersal in a Holarctic sea duck

Jeffrey L. Peters, Kimberly A. Bolender & John M. Pearce
Genetic studies of waterfowl (Anatidae) have observed the full spectrum of mitochondrial (mt) DNA population divergence, from panmixia to deep, reciprocally monophyletic lineages. Yet these studies generally found weak or no nuclear (nu) DNA structure which was often attributed to sex-biased gene flow (i.e., male dispersal and female philopatry), a common behavior within this family. An alternative explanation for this “conflict” is that the smaller effective population size and faster sorting rate of mtDNA relative...

Data from: Genetic and phenotypic divergence between low- and high-altitude populations of two recently diverged cinnamon teal subspecies

Robert E. Wilson, Jeffrey L. Peters & Kevin G. McCracken
Spatial variation in the environment can lead to divergent selection between populations occupying different parts of a species’ range, and ultimately lead to population divergence. The colonization of new areas can thus facilitate divergence in beneficial traits, yet with little differentiation at neutral genetic markers. We investigated genetic and phenotypic patterns of divergence between low- and high-altitude populations of cinnamon teal inhabiting normoxic and hypoxic regions in the Andes and adjacent lowlands of South America....
