TL;DR: The hypothesis that variation in life history traits in natural populations is likely to be determined by many loci of small effect spread throughout the genome is supported, subject to continued input of variation by mutation and migration, although it cannot exclude the possibility of an additional input of major effect genes influencing either trait.

TL;DR: This study used a suite of approaches to investigate the genetic architecture of eight quantitative traits in two long‐term study populations of great tits—one in the Netherlands and the United Kingdom and found little evidence for the presence of genes of large effects in either population.

TL;DR: A very strong genetic divergence between wild sea beet and other relatives was found, which was unexpected given the recent evolutionary history and the full cross-compatibility of all taxa, and it was definitely confirmed that the classification into cultivated, wild, ruderal and weed forms is clearly in accordance with genetic clustering despite the very recent domestication process of sugar beet.

TL;DR: A unique genomics toolkit was developed for the great tit, a model species in ecology and behavioural biology, and it is shown that SNPs identified in either of the two populations have a high genotyping success in the other population.

TL;DR: Fine‐scale genetic structure relative to dispersal capabilities suggests ecological and evolutionary mechanisms maintain within‐population genetic diversity in this population with the potential to drive microevolutionary change.
