Understanding molecular mechanisms of sexually dimorphic organ growth is a fundamental
problem of developmental biology. Recent quantitative studies showed that the Drosophila …

Abstract Changes in facial expression provide cues for assessing emotional states in
mammals and may provide non-verbal signals of pain. This study uses geometric …

The compound eyes of insects exhibit stunning variation in size, structure, and function,
which has allowed these animals to use their vision to adapt to a huge range of different …

Background Insects have evolved complex visual systems and display an astonishing range
of adaptations for diverse ecological niches. Species of Drosophila melanogaster subgroup …

Background Recent technological advances opened the opportunity to simultaneously study
gene expression for thousands of individual cells on a genome-wide scale. The …

Revealing the mechanisms underlying the breathtaking morphological diversity observed in
nature is a major challenge in Biology. It has been established that recurrent mutations in …

Speciation with gene flow is now widely regarded as common. However, the frequency of
introgression between recently diverged species and the evolutionary consequences of …

The compound eyes of insects exhibit extensive variation in ommatidia number and size,
which affects how they see and underlies adaptations in their vision to different …

Variation in Drosophila compound eye size is studied in various research contexts ranging
from evolutionary to biomedical studies. Studying this variation requires the collection of …

Throughout life, organisms interact with a wide range of factors that collectively shape their
behaviour, physiology, and mortality, driving ecological and evolutionary processes in …
