Aggressive social interactions are used to compete for limited resources and are regulated
by complex sensory cues and the organism's internal state. While both sexes exhibit …

During courtship, multiple information sources are integrated in the brain to reach a final
decision, ie, whether or not to mate. The brain functions for this complex behavior can be …

Dimorphic traits, shaped by both natural and sexual selection, ensure optimal fitness and
survival of the organism. This includes neuronal circuits that are largely affected by different …

Climate warming is expected to increase the energy demands of ectotherms by accelerating
their metabolic rates exponentially. However, this prediction ignores environmental …

Developing animals are increasingly exposed to elevated temperatures as global
temperatures rise as a result of climate change. Vertebrates can be affected by elevated …

Ovaries play key roles in fitness and evolution: they are essential female reproductive
structures that develop and house the eggs in sexually reproducing animals. In Drosophila …

In the resource-defence mating system, where males compete for limited resources to
acquire females, male traits associated with fighting ability are selected, leading to the …

Females increase aggression for mating opportunities and for acquiring reproductive
resources. Although the close relationship between female aggression and mating status is …

Abstract Model organisms such as Drosophila melanogaster have been key tools for
advancing our fundamental and applied knowledge in biological and biomedical sciences …
