#LiteratureNotice Rêgo et al. Repeatability of evolution and genomic predictions of temperature adaptation in seed beetles doi.org/10.1038/s415... #Beetle #Beetles #evolution
a, Populations were collected from California (yellow), Brazil (teal) and Yemen (orange) and adapted to benign lab conditions (29 °C) for approximately 200 generations. Thermal performance curves (with 95% confidence intervals shown as shaded bands) of the three populations show the classic asymmetric shape and depict how population growth rate (adult offspring production/generation time) changes with temperature. While mean growth rates are slightly lower at 23 °C compared with 35 °C, the slope of the performance curve is steeper at temperatures higher than the optimum. To start experimental evolution, lines were placed at either 23 °C or 35 °C, with two replicates in each treatment per genetic background. Horizontal black bars in the arrows depicting each experimental evolution line indicate the time at which lines were sequenced. The sequencing of heat-adapted lines at generation 3 represent the genomic estimates of ancestral variation. b–e, For both the seven life-history phenotypes (b,c) and for all genomic SNPs (d,e), principal component analysis (PCA) summaries are presented of evolutionary change between ancestral (grey) and heat- (red) and cold-adapted (blue) lines. Phenotypes were measured in a common garden design including both the low and high temperature. The world map was generated using the R packages ggplot and maps.
