## Abstract

> This study quantifies the tissue content of four biogenic amines in the brains of red harvester ants from different colonies, linking foraging behavior to neurotransmitter signaling. Using capillary electrophoresis coupled with fast-scan cyclic voltammetry, the research reveals significant variation in neurotransmitter levels among colonies in a natural environment.

## Keywords

`neurotransmitters` · `dopamine` · `serotonin` · `octopamine` · `tyramine` · `Pogonomyrmex barbatus` · `CE-FSCV` · `biogenic amines` · `colony variation`

## Key Contributions

- First measurements of biogenic amine tissue content in single forager ant brains from natural populations.
- Demonstration of capillary electrophoresis coupled with fast-scan cyclic voltammetry as an effective method for neurotransmitter analysis in small samples.
- Identification of significant differences in neurotransmitter levels across ant colonies, suggesting environmental influences on biogenic amine signaling.
- Establishment of a foundation for future studies correlating neurotransmitter content with ant foraging behavior.

## Methods

- Utilized capillary electrophoresis with fast-scan cyclic voltammetry (CE-FSCV) for neurotransmitter detection.
- Field-amplified sample stacking was employed to enhance detection limits of neurotransmitters in single ant brains.
- Ant brains were dissected and homogenized in a controlled environment to prepare samples for analysis.
- Statistical analysis was performed using GraphPad Prism to evaluate variations in neurotransmitter content.
