An overlooked DNA source for non‐invasive genetic analysis in birds
It was found that feather clots from museum specimens provided results nearly as good as footpad and better than those from the more commonly used museum skin snips.
Population genetics after fragmentation: the case of the endangered Spanish imperial eagle (Aquila adalberti)
How management strategies should aim at the maintenance of current genetic variability levels and the avoidance of inbreeding depression through the connection of the different nuclei is discussed.
Population fragmentation leads to spatial and temporal genetic structure in the endangered Spanish imperial eagle
The results indicate an ancestral panmictic situation for the species that management policies should aim to restore, and temporal fluctuations in mitochondrial and microsatellite allelic frequencies were found between the historical and the current population.
Extreme genomic erosion after recurrent demographic bottlenecks in the highly endangered Iberian lynx
A series of severe population bottlenecks in the history of the Iberian lynx that predate its known demographic decline during the 20th century and have greatly impacted its genome evolution are identified.
Sex-Specific Genetic Structure and Social Organization in Central Asia: Insights from a Multi-Locus Study
It is shown that in patrilineal herder groups of Central Asia, in contrast to bilineal agriculturalists, the effective number of women is higher than that of men, and this study suggests that differences in sex-specific migration rates may not be the only cause of contrasting male and female differentiation in humans, and that Differences in effective numbers do matter.
Uniparental Markers in Italy Reveal a Sex-Biased Genetic Structure and Different Historical Strata
Analysis of uniparentally-inherited markers in ∼900 individuals across the Italian peninsula, Sardinia and Sicily revealed a sex-biased pattern indicating different demographic histories for males and females and a North West–South East Y-chromosome structure is found in continental Italy.
The Basque paradigm: genetic evidence of a maternal continuity in the Franco-Cantabrian region since pre-Neolithic times.

Overall, the results reveal a certain genetic inter-population diversity, especially among Berber groups, and sexual asymmetry, paternal lineages being mostly of autochthonous origin.
In the heartland of Eurasia: the multilocus genetic landscape of Central Asian populations
The results suggest that the recurrent expansions of eastern nomadic groups did not result in the complete replacement of local populations, but rather into partial admixture, which reveals that Central Asian diversity is mainly shaped by linguistic affiliation.
Afghanistan's Ethnic Groups Share a Y-Chromosomal Heritage Structured by Historical Events
This study has analyzed, for the first time, the four major ethnic groups in present-day Afghanistan: Hazara, Pashtun, Tajik, and Uzbek, using 52 binary markers and 19 short tandem repeats on the non-recombinant segment of the Y-chromosome to suggest all current Afghans largely share a heritage derived from a common unstructured ancestral population.
