Half a million species of herbivorous insects have been described. Most of them are diet
specialists, using only a few plant species as hosts. Biologists suspect that their specificity is …

Theory generally predicts that host specialisation and dispersal should evolve jointly.
Indeed, many models predict that specialists should be poor dispersers to avoid landing on …

Host shifts can lead to ecological speciation and the emergence of new pests and
pathogens. However, the mutational events that facilitate the exploitation of novel hosts are …

Transcriptomic studies lend insights into the role of transcriptional plasticity in adaptation
and specialization. Recently, there has been growing interest in understanding the …

Diverse geographic, environmental, and ecological factors affect gene flow and adaptive
genomic variation within species. With recent advances in landscape ecological modelling …

Understanding the evolutionary processes that influence fitness is critical to predicting
species' responses to selection. Interactions among evolutionary processes including gene …

When gene flow accompanies speciation, recombination can decouple divergently selected
loci and loci conferring reproductive isolation. This barrier to sympatric divergence …

Highlights•Insect transcriptome expression has revealed responses to use of different plant
hosts.•Host plant adaptation involves detoxification and metabolism of secondary …

Despite accumulating evidence that evolution can be predictable, studies quantifying the
predictability of evolution remain rare. Here, we measured the predictability of genome‐wide …

Plants and their specialized flower visitors provide valuable insights into the evolutionary
consequences of species interactions. In particular, antagonistic interactions between …
