Cleaner ants in the desert!
I think this paper beautifully illustrates how much we don't know about ants and their relationships with other species!
I took this modeling course in 2022 and really enjoyed it! The course provided me with a great framework to understand modeling papers. So if you are interested in modeling in biology in any capacity, check out the pre-print below!
📣SEMINAR SERIES 2026📣
Our 1st seminar of this year !
📆Tuesday 28th April 2026 at 2pm GMT on Youtube: Dr. Anna Dornhaus (@dornhaus.bsky.social) on “What we learned about the world from studying collective behavior: algorithms, replicators, and strong inference” 🐜

Thank you very much Erica!
Future experiments examining how individual abandonment affects colony-level foraging will allow us to disentangle these explanations. Moreover, application of this framework in a comparative context can allow us to understand how and when robustness is prioritized in collective systems (6/6).
This implies a lack of robustness against pheromone trail disruption. However, colony-level foraging may be modular due to several concurrent pheromone trails. This would allow workers to switch to an intact trail, thereby buffering them against such a perturbation (5/6).
Most ants continued to make random choices, showing a high reliance on pheromone trail for navigation. Fire ants can easily monopolize a food source with a huge and aggressive workforce, thereby reducing colonies’ investment per forager in being successful at food recovery (4/6).
We found that most ants abandoned the food source in response to trail perturbation! However, ants were more persistent and less likely to abandon a high-quality food source. But this persistence did not translate to successful foraging. Why? (3/6)
We removed a small section of the pheromone trail leading to a low or a high-quality food source on a T-maze setup and examined individual ant responses. We utilized the robustness mechanism framework from systems biology to interpret ant responses to this perturbation (2/6).
Paper alert 🚨🐜! Fire ant foraging looks remarkably robust until you perturb their communication. @dornhaus.bsky.social and I tested how fire ants respond to disruptions in pheromone trail communication during foraging. More in the thread below 🧵(1/6).

Especially interesting perhaps if you're into acoustics, graphical design, realtime visualisations, and algorithms.
Please do spread the word and forward in your circles.

Great article! Sorry to hear that your celebratory posts attracted so much hatred for no reason. Kudos to you for leveraging vitriol into an opportunity! I have your thesis and papers on my reading list!
I really liked this line: 'Visibility is not vanity; it’s part of building a career.' So true!
It’s me!

Fascinating findings!
This is what I love about behavioral ecology experiments. Simple and clever experimental designs can elegantly answer important questions.
