Recent advances in population history reconstruction offered a powerful tool for comparisons of the abilities of sexual and clonal forms to respond to Quaternary climatic oscillations, ultimately leading to inferences about the advantages and disadvantages of a given mode of reproduction. We reconstructed the Quaternary historical biogeography of the sexual parental species and clonal hybrid lineages within the Europe‐wide hybrid complex of Cobitis spiny loaches. Cobitis elongatoides and… 
European colonization by the spined loach (Cobitis taenia) from Ponto‐Caspian refugia based on mitochondrial DNA variation
TLDR
The phylogeography of the spined loach, Cobitis taenia, is investigated using 1126 bp of the mitochondrial cytochrome b gene from 174 individuals collected at 47 sites, revealing a history of recent expansion and isolation by distance.
Distinguishing between Incomplete Lineage Sorting and Genomic Introgressions: Complete Fixation of Allospecific Mitochondrial DNA in a Sexually Reproducing Fish (Cobitis; Teleostei), despite Clonal Reproduction of Hybrids
TLDR
Cobitis complex supports the view that the type of resulting hybrids depends on a level of genomic divergence between sexual species, and suggests that introgressive hybridizations are rather old episodes, mediated by previously existing hybrids whose inheritance was not entirely clonal.
Around or across the Carpathians: colonization model of the Danube basin inferred from genetic diversification of stone loach (Barbatula barbatula) populations
TLDR
Co‐existence of highly divergent mtDNA lineages in a single river system shows that range shifts in response to climatic changes during the Quaternary did not cause extensive genetic homogenization in the stone loach populations, and indicates that the Pleistocene glaciations promoted the dispersal and mixing of populations through the lowlands.
Dynamic Formation of Asexual Diploid and Polyploid Lineages: Multilocus Analysis of Cobitis Reveals the Mechanisms Maintaining the Diversity of Clones
TLDR
Fine-scale genetic analysis of Central European hybrid zone between two sexual species using microsatellite genotyping and mtDNA sequencing found that the hybrid zone is populated by an assemblage of clonally (gynogenetically) reproducing di-, tri- and tetraploid hybrid lineages and that successful clones recruit from two ploidy levels, i.e. diploid and triploid.
Genomic replacement of native Cobitis lutheri with introduced C. tetralineata through a hybrid swarm following the artificial connection of river systems
TLDR
The results suggest that the gene pool of native C. lutheri is being rapidly replaced by that of continually introducing C. tetralineata through a hybrid swarm for the last 80 years, which will ultimately lead to the genomic extinction of natives in this hybrid zone.
Morphological Relationships Between Polyploid Hybrid Spined Loaches of the Genus Cobitis (Teleostei: Cobitidae) and their Parental Species
TLDR
Discriminant function analysis for biometrical characters and description of qualitative features indicate the morphological distinctness of the two diploid species C. taenia and C. elongatoides.
Hybrid asexuality as a primary postzygotic barrier between nascent species: On the interconnection between asexuality, hybridization and speciation
TLDR
The results suggest that hybridization leads to sexual hybrids at the initial stages of speciation, but as the species diverge further, the gradual accumulation of reproductive incompatibilities between species could distort their gametogenesis towards asexuality.
Inconsistent phylogeographic pattern between a sperm dependent fish and its host: in situ hybridization vs dispersal
TLDR
The unusually high diversity of hybrid lineages in East-Qc as well as the spatial organization and the close genetic relationship with C. eos sympatric populations support the hypothesis that multiple hybridization events occurred in situ.
The gynogenetic reproduction of diploid and triploid hybrid spined loaches (Cobitis: Teleostei), and their ability to establish successful clonal lineages—on the evolution of polyploidy in asexual vertebrates
TLDR
Genotyping of the progeny using allozymes and multilocus DNA fingerprinting, along with flow cytometric measurement of ploidy level, demonstrated the occurrence of gynogenetic reproduction in both female biotypes, consistent with the existence of developmental constraints on tetraploidy.

Reconstruction of the evolutionary history of asexual lineages undermines their suitability as models for the studies of evolutionary consequences of sexual reproduction. Using molecular tools we

Phylogeography and postglacial dispersion of the chub (Leuciscus cephalus) in Europe
TLDR
A phylogeographic analysis of mitochondrial DNA variation was performed in order to test the hypothesis of a postglacial recolonization of mid‐ and north‐European rivers from a Danubian refuge, providing strong evidence for the eradication of this species from most of Europe during maximum ice extent.
Clonal diversity and polyphyletic origins of hybrid and spontaneous parthenogenetic Campeloma (Gastropoda: Viviparidae) from the south‐eastern United States
TLDR
This work reports on the origin, clonal diversity and population structure of hybrid and spontaneous parthenogens from south‐eastern United States populations of the freshwater snail Campeloma, finding that levels of genotypic diversity are significantly higher in sexual C. limum.
Circum Black Sea phylogeography of Barbus freshwater fishes: divergence in the Pontic glacial refugium
TLDR
DNA sequence variation at the mitochondrial cytochrome b gene is used to assess the phylogeography of Barbus fishes in the Black Sea region and suggests that multiple refugial populations survived over several later glaciations in the vicinity of theBlack Sea.
Antiquity of clonal salamander lineages revealed by mitochondrial DNA
TLDR
The low mtDNA variability in the clonal lineages suggests that they have undergone population reductions during the Pleistocene, far longer than estimated for other clonal vertebrate populations.
Phylogeography of competing sexual and parthenogenetic forms of a freshwater flatworm: patterns and explanations
TLDR
The data suggest that repeated hybridisation between sexuals and parthenogenetic lineages in mixed populations maintains high levels of genetic diversity in parthenogens, which can explain why parthenogenic persist in populations that were originally sexual.
Separating population structure from population history: a cladistic analysis of the geographical distribution of mitochondrial DNA haplotypes in the tiger salamander, Ambystoma tigrinum.
TLDR
This paper shows how a nested cladistic analysis of geographical distances can be used to test the null hypothesis of no geographical association of haplotypes, test the hypothesis that significant associations are due to restricted gene flow, and identify patterns of significant association that is due to historical events.
Molecular evidence for multiple origins of hybridogenetic fish clones (Poeciliidae:Poeciliopsis).
TLDR
It is hypothesized that a dynamic complex of sexual and clonal fishes appear to participate in a feedback process that maintains genetic diversity in both the sexual and asexual components.
