The mottled duck (Anas fulvigula) is a year-round endemicresident of the Gulf Coast and one of two non-migratory dabbling ducksthat inhabit North America. To investigate population genetic structureof allopatric mottled duck populations, we collected 5' control regionsequences (bp 78–774) from the mitochondria of 219 mottled duckssampled at 11 widely spaced geographic localities in Texas, Louisiana,and Florida and compared them to each other and to homologous sequencesfrom 4 Mexican ducks (A… 

Old divergence and restricted gene flow between torrent duck (Merganetta armata) subspecies in the Central and Southern Andes

TLDR
It is suggested that the South American Arid Diagonal was preexisting and remains a current phylogeographic barrier between the ranges of the two torrent duck subspecies, and the adult territoriality and breeding site fidelity to the rivers define their population structure.

POPULATION STRUCTURE AND MITOCHONDRIAL POLYPHYLY IN NORTH AMERICAN GADWALLS (ANAS STREPERA)

TLDR
Female-mediated gene flow, along with both historical and contemporary population and range expansions, has likely contributed to the overall weak mtDNA structure in North American Gadwalls.

A Comparison of Hybridization between Mottled Ducks (Anas fulvigula)and Mallards (A. platyrhynchos) in Florida and South Carolina using Microsatellite DNA Analysis

TLDR
Genetic variation among 225 mottled ducks and mallards is assessed using five microsatellite loci, and significant overall differences between these species within two geographic areas are detected, indicating a genetic component would be appropriate in actively managing interspecific hybridization in Florida mottling ducks.

Rapid radiation and hybridization contribute to weak differentiation and hinder phylogenetic inferences in the New World Mallard complex (Anas spp.)

TLDR
Neither population structure analyses nor coalescent-based gene flow estimates conclusively identified the presence of hybrids or significant gene flow, suggesting that genetic similarity within the Mallard complex is largely influenced by incomplete lineage sorting, however, this cannot reject potentially high levels of gene flow.

ASYMMETRIC HYBRIDIZATION AND SEX-BIASED GENE FLOW BETWEEN EASTERN SPOT-BILLED DUCKS (ANAS ZONORHYNCHA) AND MALLARDS (A. PLATYRHYNCHOS) IN THE RUSSIAN FAR EAST

TLDR
Se sequencing of the maternally inherited mitochondrial DNA control region and ODC-6 allele sequences revealed two divergent groups of haplotypes and alleles in the Eastern Spot-billed Duck, which were monophyletic and diverged by 2–16 substitutions.

Mitochondrial phylogeography, subspecific taxonomy, and conservation genetics of sandhill cranes (Grus canadensis; Aves: Gruidae)

TLDR
Analysis of mitochondrialDNA control region (CR) sequences indicates that there is significant population genetic differentiation among all subspecies except G. c.

ASYMMETRIC HYBRIDIZATION AND SEX-BIASED GENE FLOW BETWEEN EASTERN SPOT-BILLED DUCKS (ANAS ZONORHYNCHA) AND MALLARDS (A. PLATYRHYNCHOS) IN THE RUSSIAN FAR EAST

TLDR
This analysis is the first to document the existence of two divergent haplotype and allele lineages in Asian mallard species and suggests that Eastern Spot-billed Ducks are more closely related to North America's Mottled, American Black, and Mexican ducks than they are to Mallards, which occur sympatrically in East Asia.

PHYLOGEOGRAPHY OF THE MALLARD (ANAS PLATYRHYNCHOS): HYBRIDIZATION, DISPERSAL, AND LINEAGE SORTING CONTRIBUTE TO COMPLEX GEOGRAPHIC STRUCTURE

TLDR
Overall weak phylogeographic structure and low genetic differentiation within Asia, and between Asia and North America when only group A haplotypes were evaluated, is probably explained by large long-term population sizes and significant intra-continental dispersal.

Genetic Differentiation of Dabbling Ducks (Anseriformes: Anas) Populations From Palaearctic in Time and Space

TLDR
The data obtained from genetic distances revealed that Mallards of Lithuania form no discrete populations and vary temporarily and spatially.

Mitochondrial Analysis of Gene Flow between New Zealand Mallards (Anas Platyrhynchos) and Grey Ducks (A. Superciliosa)

TLDR
The contention that hybridization between Mallards and nondimorphic species involves primarily Mallard males with females of the other species is not upheld for this example from New Zealand, and the speciation process appears to be undergoing reversal.

Phylogeny and biogeography of dabbling ducks (genus: Anas): A comparison of molecular and morphological evidence

TLDR
It is suggested that the high dispersal ability of birds (especially dabbling ducks) has important implications for recovery of branches using molecular systematics and Geographic origin for most internal branches is ambiguous using several reconstruction methods.

MITOCHONDRIAL GENE TREES AND THE EVOLUTIONARY RELATIONSHIP OF MALLARD AND BLACK DUCKS

TLDR
Overall, the mtDNA data indicate an extremely close evolutionary relationship between Mallards and Black Ducks, and in conjunction with the geographic distributions suggest that the Black Duck is a recent evolutionary derivative of a more broadly distributed Mallard‐Black ancestor.

Transfer of mitochondrial DNA from the northern red-backed vole (Clethrionomys rutilus) to the bank vole (C. glareolus)

TLDR
The presence of two distinctly different mtDNA lineages within Clethrionomys glareolus may be a consequence of a limited episode of hybridization between C. glareolu and C. rutilus, probably during the postglacial recolonization of Fennoscandia 8000–13,000 years ago.

Low genic variation between Black Ducks and Mallards

TLDR
The genetic data do not support even subspecific status for the Black Duck, and the only taxonomic choices are to continue to consider them as separate species or to conclude that the Black duck is a color morph of the Mallard.

A phylogenetic analysis and classification of recent dabbling ducks (Tribe anatini) based on comparative morphology

TLDR
Cladistic analysis of 157 characters of definitive plumages and soft parts, natal plumages, tracheae, and nontracheal skeletons of 59 Anatini provided a phylogenetic hypothesis of high consistency and resolution and indicated that interspecific interfertility is a poor indicator of relationship.

Structural conservation and variation in the mitochondrial control region of fringilline finches (Fringilla spp.) and the greenfinch (Carduelis chloris).

TLDR
In pairwise comparisons among finch species, the central domain has unusually low transition/transversion ratios, which suggests that increased G + T content is a functional constraint, possibly for DNA primase efficiency.

Ancient DNA and island endemics

TLDR
The combination of ancient DNA and palaeontological techniques can provide information necessary for conservation management of the endangered Laysan duck and resolve the identity of subfossil duck bones.

Mitochondrial DNA differentiation during the speciation process in Peromyscus.

TLDR
The theoretical and empirical results for mtDNA in maniculatus and polionotus appear to conform closely to case III, and it is suggested that the distribution patterns of mtDNA sequence variation within and among extant species should be of considerable relevance to the particular demographies of speciation.
