Discordance between mitochondrial and nuclear DNA has been noted in many systems. Asymmetric introgression of mitochondria is a common cause of such discordances, although in most cases the drivers of introgression are unknown. In the yellow‐rumped warbler, evidence suggests that mtDNA from the eastern, myrtle warbler, has introgressed across much of the range of the western form, the Audubon's warbler. Within the southwestern United States myrtle mtDNA comes into contact with another clade… 
Introgression of mtDNA in Urosaurus lizards: historical and ecological processes
TLDR
Investigating mito‐genome introgression between the lizard species Urosaurus graciosus and U. ornatus finds changes indicate a potential selective disadvantage for individuals with heterospecific mitochondria and are consistent with the theoretical expectation that deleterious alleles are more likely to persist in expanding populations.
Signatures of mitonuclear coevolution in a warbler species complex
TLDR
It is shown that such mitonuclear coevolution might be maintained by climate-related selection, becauseMitonuclear ancestry is correlated with climatic conditions among sampling sites, and this observation suggests climatic-associated adaptation shaping miton nuclear differentiation and introgression in this species complex.
Hybridization and mitochondrial genome introgression between Rana chensinensis and R. kukunoris
TLDR
It is suggested that selective advantages of the R. kukunoris‐type mito‐genome in thermal adaptation may also contribute to the introgression between the two species, and support for the sex‐biased dispersal hypothesis is weak.
A reassessment of explanations for discordant introgressions of mitochondrial and nuclear genomes
TLDR
The results dismiss several popular hypotheses, and provide support for adaptive mitochondrial introgression, by using individual‐based, multilocus, computer simulations of secondary contact under a wide range of demographic and genetic scenarios to evaluate the ability of the different mechanisms to produce discordantintrogression.
Positive and purifying selection in mitochondrial genomes of a bird with mitonuclear discordance
TLDR
Signs of positive, divergent selection on mitochondrial genes in E. australis are found and it is discussed whether this selection may reflect local environmental adaptation, a by‐product of other selective processes, or genetic incompatibilities, and how these hypotheses can be tested in future.
The effects of allospecific mitochondrial genome on the fitness of northern redbelly dace (Chrosomus eos)
TLDR
Allopatry of cybrids restricted to the postglacial expansion suggests the existence of higher fitness for cybrids in specific conditions, allowing for the colonization of different environments and expanding the species’ range.
Interactions between nuclear genes and a foreign mitochondrial genome in the redbelly dace Chrosomus eos.
Introgression and selection shaped the evolutionary history of sympatric sister‐species of coral reef fishes (genus: Haemulon)
TLDR
It is suggested that hybridization in the recent past led to introgression of the mtDNA, with little effect on the nuclear genome, which provides a mechanism for the evolution of independent lineages despite recurrent hybridization events.
Complex histories of gene flow and a mitochondrial capture event in a nonsister pair of birds
TLDR
It is suggested that a Pleistocene extinction of S. guttula from mainland Australia resulted from range expansion by S. trivirgatus, and neutral demographic processes, not adaptive introgression, are the most likely cause of these complex population histories.

TLDR
There is great potential for certain cases of mitochondrial introgression to become important natural systems within which to test the effect of different mitochondrial genotypes on whole‐animal phenotypes.
Introgression of mitochondrial DNA among Myodes voles: consequences for energetics?
TLDR
The results show that the phenotypic traits vary markedly along the north-south axis of populations of M. glareolus, and Mitochondrial sequence variation in the introgressed haplotypes is compatible with demographic growth of the populations, but may also be a result of positive selection.
Incipient Speciation Despite Little Assortative Mating: The Yellow-Rumped Warbler Hybrid Zone
TLDR
A study of a classic avian hybrid zone in North America between two subspecies of the yellow-rumped warbler, which shows that despite extensive hybridization the two forms are distinct evolutionary groups carrying genes for divergent adaptive peaks, and this situation appears relatively stable.
Hybrid origin of Audubon’s warbler
TLDR
Analysis of nuclear amplified fragment length polymorphism (AFLP) and sequence markers shows that Audubon’s warblers are genetically intermediate and carry a mixture of alleles otherwise found only in one or the other of their putative parental species.
A cryptic contact zone between divergent mitochondrial DNA lineages in southwestern North America supports past introgressive hybridization in the yellow-rumped warbler complex (Aves: Dendroica coronata)
TLDR
Analysis of morphological traits shows that memorabilis is significantly differentiated from auduboni and nigrifrons in some traits, yet is overall intermediate between the two, which is consistent with a shared common ancestor for the Audubon's warbler group.
Speciation and rapid phenotypic differentiation in the yellow‐rumped warbler Dendroica coronata complex
The relative importance of the Pleistocene glacial cycles in driving avian speciation remains controversial, partly because species limits in many groups remain poorly understood, and because current

TLDR
There has been mitochondrial gene flow between these species for a long enough time that several nuclear loci examined could diverge because of accumulation of neutral mutations.
EXPERIMENTAL EVIDENCE FOR MITOCHONDRIAL DNA INTROGRESSION BETWEEN DROSOPHILA SPECIES
TLDR
The hypothesis that a selective advantage of hybrids (probably at the nuclear level) has promoted mtDNA transfer from D. simulans Madagascar or Reunion populations into D. mauritiana through introgressive hybridization is supported.

TLDR
Analysis of plumage, morphology, and mitochondrial (COI) and nuclear molecular markers (CHD1Z and numt-Dco1) shows surprisingly extensive hybridization between Townsend’s warblers, with at least 38% of individuals in the hybrid zone being either hybrids or backcrosses.
