Knowledge about population structure and connectivity of waterfowl species, especially mallards (Anas platyrhynchos), is a priority because of recent outbreaks of avian influenza. Ringing studies that trace large‐scale movement patterns have to date been unable to detect clearly delineated mallard populations. We employed 363 single nucleotide polymorphism markers in combination with population genetics and phylogeographical approaches to conduct a population genomic test of panmixia in 801… 
Investigating the puzzling genetic structure of mallard populations (Anas platyrhynchos L.) in Italy
TLDR
In most Italian sites, a large admixture of mallard strains were observed, whereas significant genetic differentiation levels were found between urban and wild populations and among the wild population from North America and all European populations.
Environmental differences explain subtle yet detectable genetic structure in a widespread pollinator
TLDR
The potential of incorporating environmental differences among population locations to complement the more traditional approach of isolation by geographic distance is highlighted in order to obtain a holistic understanding of the processes driving structure in natural populations.
Interspecific hybridization contributes to high genetic diversity and apparent effective population size in an endemic population of mottled ducks (Anas fulvigula maculosa)
TLDR
Analysis of DNA sequences from six independent loci found that introgression of mallard alleles has helped maintain high genetic diversity in mottled ducks and might be important for the adaptability and survival of this species.
Flyway structure in the circumpolar greater white‐fronted goose
TLDR
The results do not provide strong support for the various taxonomic proposals for this species except for supporting the distinctness of two isolated breeding populations within Cook Inlet, Alaska and Greenland, consistent with their subspecies status.
Geographical features are the predominant driver of molecular diversification in widely distributed North American whipsnakes
TLDR
The findings suggest that multiple features of the North American landscape contributed to allopatric divergence in this widely distributed snake group.
Genetic consequences of breaking migratory traditions in barnacle geese Branta leucopsis
TLDR
The results suggest that migratory traditions in populations are subject to change in geese and that such changes have population genetic consequences, and argue that the emergence of nonmigration probably resulted from developmental plasticity.
Comparative population structure of cavity-nesting sea ducks
TLDR
The smallest cavity-nesting waterfowl species, the Bufflehead, exhibited the lowest level of population differentiation due to increased dispersal and gene flow, which will aid management objectives that require an understanding of population delineation and migratory connectivity between breeding and wintering areas.
New insights into the phylogenetics and population structure of the prairie falcon (Falco mexicanus)
TLDR
California’s prairie falcons might be managed as a single population, indicating that management actions undertaken to benefit the species at the local level have the potential to influence the species as a whole.
Population Genomics and Phylogeography
TLDR
How genomic data from avian species have advanced the authors' understanding of each of these five processes is reviewed, including an emphasis on their interactions in shaping contemporary genetic diversity on the scale of whole populations.

Evolution and connectivity in the world-wide migration system of the mallard: Inferences from mitochondrial DNA
TLDR
This first complete assessment of the mallard's world-wide population genetic structure confirms that no more than two mtDNA clades exist and refute population classification based on flyways proposed by ornithologists and managers, because they seem to have little biological meaning.
Genome‐wide single nucleotide polymorphisms reveal population history and adaptive divergence in wild guppies
TLDR
Overall, this study demonstrates the power of a genome‐wide SNP data set to inform for studies on natural variation, adaptation and evolution of wild populations.
Panmixia on a continental scale in a widely distributed colonial waterbird
TLDR
The lack of any genetic structure across the range of American white pelicans indicates that, unlike other waterbirds with similar life-history characteristics, extensive gene flow and presumably low philopatry appear to preclude genetic differentiation.
Range-wide genetic population structure of common pochard (Aythya ferina): a potentially important vector of highly pathogenic avian influenza viruses
TLDR
Investigation of the range-wide population genetic structure of common pochard, a long-distance migratory duck and potential vector of highly pathogenic avian influenza, suggests limited breeding-site fidelity, especially in females, but extensive population admixture on the wintering grounds.
Greater flamingo colonies around the Mediterranean form a single interbreeding population and share a common history
TLDR
Analysis of both mitochondrial DNA and microsatellites indicated that populations have undergone a bottleneck followed by rapid growth and expansion, and relevance to conservation and management of the species is discussed.
Philopatry and migration of Pacific white sharks
TLDR
It is hypothesized that this strong homing behaviour of eastern Pacific white sharks has maintained the separation of a northeastern Pacific population following a historical introduction from Australia/New Zealand migrants during the Late Pleistocene.
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.
Genome wide SNP discovery, analysis and evaluation in mallard (Anas platyrhynchos)
TLDR
Almost 150,000 SNPs in wild mallards that will likely yield good results in genotyping are identified, which indicates that a large amount of accurately inferred mallard SNPs will benefit bird evolutionary studies, ecological studies and industrial breeding programs.
The Development of a Genome Wide SNP Set for the Barnacle Goose Branta leucopsis
TLDR
The development of a genome wide SNP set for the Barnacle Goose Branta leucopsis, a model species for the study of bird migration, is presented and the genome of a related species can be used as reference to detect genome wide SNPs in birds, because genomes of birds are highly conserved.
Genetic consequences of breaking migratory traditions in barnacle geese Branta leucopsis
TLDR
The results suggest that migratory traditions in populations are subject to change in geese and that such changes have population genetic consequences, and argue that the emergence of nonmigration probably resulted from developmental plasticity.
