TL;DR: Observed high heterozygosity levels in tested populations are compatible with an overdominant model with a small selective advantage for heterozygotes, and a significant positive correlation between genetic and geographic differentiation patterns is shown.

TL;DR: In this paper, the authors carried out a 6-year experiment in mice colonized with 12 representative taxa and found that the proportions of different sub-strains are also rapidly altered after dietary shift.

TL;DR: Genetic data was analyzed for outlier markers with an overly large extent of differentiation between populations living in a tropical forest, as compared to genetically related populations living outside the forest in Africa and the Americas, suggesting that Africans and Amerindians may have followed different routes to adapt to similar environmental selective pressures.

TL;DR: Low levels of mitochondrial DNA variation were observed among pike Esox lucius populations from major drainage systems of Europe and populations from the Italian peninsula including southern Switzerland were genetically distinct from other samples.

TL;DR: SPATCHE3 as mentioned in this paper is a framework for simulating genetic data under a variety of spatially explicit evolutionary scenarios, extending previous versions of the SPLATCHE framework, including long-distance migration, spatially and temporally heterogeneous short-scale migrations, alternative hybridization models, simulation of serial samples of genetic data and a large variety of DNA mutation models.
