Ageing leads to dramatic changes in the physiology of many different tissues resulting in a
spectrum of pathology. Nonetheless, many lines of evidence suggest that ageing is driven …

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

Adaption to dietary changes is critical in the evolution of host plant ranges in polyphagous
insects. We compared three taxa of lepidopteran herbivores from the predominantly …

Host race formation, the establishment of new populations using novel resources, is a major
hypothesized mechanism of ecological speciation, especially in plant‐feeding insects. The …

Natural history is the careful observation of nature, wherever nature is. Ultimately, it is what
ecological, evolutionary, and behavioral science are supposed to explain. It is difficult to use …

Cactophilic Drosophila species provide a valuable model to study gene–environment
interactions and ecological adaptation. Drosophila buzzatii and Drosophila mojavensis are …

Alternative splicing is the highly regulated process of variation in the removal of introns from
premessenger-RNA transcripts. The consequences of alternative splicing on the phenotype …

High‐throughput transcriptome studies are breaking new ground to investigate the
responses that organisms deploy in alternative environments. Nevertheless, much remains …

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

Understanding the processes that generate and maintain genetic variation within
populations is a central goal in evolutionary biology. Theory predicts that some of this …
