Inferring admixture proportions from molecular data: extension to any number of parental populations.
The newly derived multiparental estimator is tested by Monte Carlo simulations and by generating artificial hybrid groups by pooling mtDNA samples from human populations and the general properties of the two-parental estimators seem to be retained.
Inferring admixture proportions from molecular data.
Two new estimators of admixture proportions based on a coalescent approach that explicitly takes into account molecular information as well as gene frequencies are derived and mY proves to be less biased than conventional estimators over a wide range of situations and especially for microsatellite data.
ABC as a flexible framework to estimate demography over space and time: some cons, many pros
This paper describes and critically comment on the different steps of an ABC analysis, analyse some of the published applications of ABC and provides user guidelines.
The genetic legacy of the Mongols.
The Y-chromosomal lineage identified is carried by likely male-line descendants of Genghis Khan, and it is proposed that it has spread by a novel form of social selection resulting from their behavior.
Ancient vs. recent processes as factors shaping the genetic variation of the European wild boar: are the effects of the last glaciation still detectable?
It follows that areas with high variation and differentiation represent natural reservoirs of genetic diversity to be protected avoiding translocations, and controlling some populations by hunting is not expected to affect significantly genetic variation in this species.

Previously undescribed genetic evidence is presented in contrast with this view based on mtDNA sequences from five Italian aurochsen dated between 7,000 and 17,000 years B.P. and >1,000 modern cattle from 51 breeds to suggest the European cattle may represent a more variable and valuable genetic resource than previously realized.
The genetic impact of demographic decline and reintroduction in the wild boar (Sus scrofa): A microsatellite analysis
Analysis of microsatellite loci is an important tool for estimating the genetic effect of reintroduction in the wild boar, and therefore for the development of conservation and management strategies for this species.
Computer simulations: tools for population and evolutionary genetics
This Review of the state-of-the-art of simulation software identifies applications of simulations, evaluates simulator capabilities, provides a guide for their use and summarizes future directions.

Following the most stringent current standards for validation of ancient DNA sequences, it is shown that the mtDNAs of two anatomically modern Homo sapiens sapiens individuals of the Cro-Magnon type dated at about 23 and 25 thousand years ago fall well within the range of variation of today's humans, but differ sharply from the available sequences of the chronologically closer Neandertals.
Analysis of DNA diversity by spatial autocorrelation.
Analyses of computer-generated sets of data, and of RFLP data from two natural populations, show that AIDAs allow one to objectively and simply identify basic patterns in the spatial distribution of haplotypes.
