New environments impose selective pressures that can drive the evolution of novel strategies. The obligate association between  Pseudomyrmex  ants and acacia plants (Vachellia, formerly  Acacia) creates a new environment where other organisms adapt to spend either their entire life cycle or a part of it. These organisms tend to be specialized and show a strong preference for living on plants defended by ants compared to other plants.

This thesis project theme aims to fill various knowledge gaps regarding the behavior of acacia ants. Therefore, research topics may focus on aspects such as: communication mechanisms, phenotypic plasticity of both the plant and the ant, queen establishment on seedlings, environmental effects on mutualism, behavior and interaction types in endemic species of Panama, as well as in little-studied species from Central America and Panama. Additionally, the thesis could explore aspects of behavior, biochemistry, or anatomy of organisms that specialize in living on these plants, particularly in a phylogenetic context (e.g., comparative studies with closely related species).
 

Internship Learning Opportunities

1. Although the specific techniques and topics depend on the applicant’s interests, the intern will learn to:
2. Develop scientific research projects.
3. Summarize and review the most relevant scientific articles for their study.
4. Maintain a field notebook and record natural history observations relevant to their research questions.
5. Manage databases, conduct statistical analyses, and follow best practices for making data publicly available in repositories.
6. Create outreach materials for the general public and support science communication initiatives.
7. Design behavioral studies to examine organisms primarily in their natural environment [depending on the chosen topic].
8. Understand the anatomy, ecology, and biology of ants or other insects [depending on the chosen topic].
9. Learn basic chemical ecology [depending on the chosen topic].
10. Gain experience with microscopy techniques and image analysis.

This research area allows for creativity and the opportunity to propose innovative ideas aligned with personal learning interests. Therefore, we expect the intern to be actively involved in reasoning and planning their thesis project, demonstrating hard work, motivation, independence, proactivity, and creativity. Additionally, we encourage active participation in the STRI community and lab activities.

Optional but desirable:  Ability to drive a manual vehicle.
