## Abstract

> This study investigates the context-dependent expression of the foraging gene in field colonies of harvester ants, focusing on the roles of age, environment, and task. By examining gene expression across different worker groups and under varying light conditions, the research highlights the complex interactions that influence foraging behavior.

## Keywords

`dopamine` · `foraging behavior` · `Pogonomyrmex barbatus` · `neuromodulation` · `task allocation` · `behavioral pharmacology` · `biogenic amines` · `harvester ants`

## Key Contributions

- Demonstrated the temporal regulation of the foraging gene in harvester ants based on age and task.
- Provided evidence of significant daily oscillations in foraging gene expression linked to activity rhythms.
- Investigated the effects of light exposure on foraging gene expression in brood workers and foragers.
- Established correlations between foraging gene expression and the circadian clock gene, cycle.

## Methods

- Collected harvester ant workers from natural populations and categorized them into age- and task-related groups.
- Conducted field experiments to assess foraging gene expression at different times of day.
- Manipulated light conditions to evaluate their impact on gene expression in various worker tasks.
- Analyzed mRNA levels of the foraging gene and the circadian clock gene in relation to worker activity.
