# On the expression of reproductive plasticity in Drosophila melanogaster females in spatial and socially varying environments

## TL;DR

This study shows how female fruit flies adjust their mating behaviors in response to different social and physical environments.

## Contribution

The study reveals new insights into reproductive plasticity in Drosophila melanogaster under varying social and spatial conditions.

## Key findings

- Mating latency decreased with more males and smaller chambers.
- Mating durations were longer in larger chambers and with two males.
- Behaviors are sensitive to local environmental changes.

## Abstract

Individuals often adjust their behaviour based on their perception and experiences with the social and/or physical environment. In this study, we examined the extent of reproductive plasticity expressed in mating rates, mating latencies, mating durations, and offspring production in female fruit flies,
Drosophila melanogaster
, that encountered different numbers of males in different sized chambers. We found that mating latency length decreased with more courting males and smaller environments and that matings durations were longer in larger chambers and in the presence of two males. These results illustrate the sensitivity of these behavioural phenotypes to changes in local environmental conditions.
