GradImpact: Studying Animal Behavior to Determine How Personality Is Shaped

    Our personalities – characteristics or qualities that form our character – are, in part, what make us unique individuals. Peter Marting, a doctoral candidate in animal behavior in the School of Life Sciences at Arizona State University, has discovered that ant colonies have unique personalities, too.


    Azteca ant colonies make their homes in Cecropia trees, which provide nutrients to the ants. In exchange, the ants act as security guards – protecting trees from choking vines and leaf-eating insects – but some colonies are better protectors than others. Marting’s research reveals that ant colonies actively displaying more aggressive behaviors protect their trees more from leaf damage than more docile colonies. Why is this important? Marting wants to better understand how the personality of an ant colony can affect its symbiotic relationships and whether there are identifiable factors that determine personality.


    Studying animal personalities is a relatively new field and observing animals in the wild can be extremely difficult given the challenges in observing consistent behavior in the same animal. However, the study system Marting uses allows him to revisit the same trees with the same colonies on a regular basis over the course of months and years. Marting takes his research one step further through a marriage with artistic expression. He has created interactive sculptures representing the ants and plants that blink with data collected from real ant colonies.

    The CGS GRADIMPACT project draws from member examples to tell the larger story of graduate education. Our goal is to demonstrate the importance of graduate education not only to degree holders, but also to the communities where we live and work. Do you have a great story to share about the impact of master’s or doctoral education? Visit our WEBSITE for more information.


    CGS is the leading source of information, data analysis, and trends in graduate education. Our benchmarking data help member institutions to assess performance in key areas, make informed decisions, and develop plans that are suited to their goals.
    CGS Best Practice initiatives address common challenges in graduate education by supporting institutional innovations and sharing effective practices with the graduate community. Our programs have provided millions of dollars of support for improvement and innovation projects at member institutions.
    As the national voice for graduate education, CGS serves as a resource on issues regarding graduate education, research, and scholarship. CGS collaborates with other national stakeholders to advance the graduate education community in the policy and advocacy arenas.  
    CGS is an authority on global trends in graduate education and a leader in the international graduate community. Our resources and meetings on global issues help members internationalize their campuses, develop sustainable collaborations, and prepare their students for a global future.
