Whole genome sequencing of 19 populations of Atlantic and Baltic herring reveals hundreds of individual loci underlying adaptation to a low salinity niche or timing of reproduction.

The adaptation of Arabidopsis plants to the local environment is linked to DNA methylation.

Single-cell time-lapse imaging and optogenetical gene recombination system uncovered that bacteria cells can overcome a deleterious genetic change of antibiotic resistance gene deletion depending on their environmental histories.

Gene knockouts provide valuable genetic fuel for climate adaptation in nature.

Baltic and Arctic ecotypes of the marine midge Clunio emerged from a recent adaptive radiation, which is based on standing genetic variation at many loci involved in time-keeping and nervous system development.

A large-scale analysis of Staphylococcus aureus within-host evolution based on a comprehensive catalogue of bacterial genetic variation reveals an excess of genome degradation signatures in infecting strains and new genetic loci of clinically relevant adaptation.

Hundreds of loci underlying ecological adaptation to different environmental conditions show striking differences in allele frequencies between ecotypes of Atlantic herring.

The dominant MRSA circulating in European livestock has stably maintained genes associated with resistance to antibiotic treatments over several decades and when it is transmitted to humans it can rapidly acquire genes that allow it to evade human immune responses.

Experiments on E. coli show that multiple mechanisms contribute to extreme resistance to ionizing radiation in bacteria, with mutations to three genes for DNA repair having a prominent role in one evolved population.

Substantial heritable genetic variation in adaptability and the pleiotropic consequences of adaptation exists in budding yeast, and can be explained by a combination of fitness and specific segregating alleles.
