Ecologically mediated selection against hybrids, caused by hybrid phenotypes fitting poorly
into available niches, is typically viewed as distinct from selection caused by epistatic …

Highlights•Sex-specific isoforms of Fruitless and Doublesex define dimorphic
circuitry.•Sensory pathways for chemical and auditory stimuli traced to the central …

In Drosophila, as well as in many other plants and animals, pigmentation is highly variable
both within and between species. This variability, combined with powerful genetic and …

Continuous color polymorphisms can serve as a tractable model for the genetic and
developmental architecture of traits. Here we investigated continuous color variation in …

Phenotypic plasticity has been proposed as a mechanism that facilitates the success of
biological invasions. In order to test the hypothesis of an adaptive role for plasticity in …

Highlights•Modification of cis-regulatory elements (CREs) often underlie morphological
evolution.•Novel gene expression patterns can emerge via the modification of preexisting …

In Drosophila melanogaster larvae, the ring gland (RG) is a control center that orchestrates
major developmental transitions. It is a composite organ, consisting of the prothoracic gland …

Recent years have seen an increase in studies that associate genomic loci with behavioral
variation both within and across animal species. Ryan York compiles and analyzes over …

Complex courtship has been well documented in the Diptera. However, studies have
focused on a limited number of taxa and mostly using lab populations, where behavior can …

Little is known about the physiological responses and genetic mutations associated with
reproductive isolation between species, especially for postmating prezygotic isolating …
