Background As global climate change and exponential human population growth intensifies
pressure on agricultural systems, the need to effectively manage invasive insect pests is …

10.7554/eLife.47138.001 The testis is a peculiar tissue in many respects. It shows patterns of
rapid gene evolution and provides a hotspot for the origination of genetic novelties such as …

Gene expression variation within species is relatively common, however, the role of natural
selection in the maintenance of this variation is poorly understood. Here we investigate low …

Early life adversity has known impacts on adult health and behavior, yet little is known about
the gene–environment interactions (GEIs) that underlie these consequences. We used the …

Studying how novel phenotypes originate and evolve is fundamental to the field of
evolutionary biology as it allows us to understand how organismal diversity is generated and …

Social interaction with conspecifics can influence the developing brain and behaviour of the
exposed animal. This experience can involve the exchange and retention of visual, chemical…

Despite decades of work, our understanding of the distribution of fitness effects of segregating
genetic variants in natural populations remains largely incomplete. One form of selection …

Ageing is a complex biological process that is accompanied by changes in gene expression
and mutational load. In many species, including humans, older fathers pass on more …

Genes with sex-biased expression in Drosophila are thought to underlie sexually dimorphic
phenotypes and have been shown to possess unique evolutionary properties. However, the …

Background Drosophila melanogaster often shows correlations between latitude and
phenotypic or genetic variation on different continents, which suggests local adaptation with …
