The paper describe TrophIE and show how it can reproduce ecological dynamics, share an open-source dataset generated by playing TrophIE and discuss the benefits and limitations of the game for the study of trophic interactions. @methodsinecoevol.bsky.social

The approach offers a simple, computationally accessible and genuinely amusing way to explore the ramifications of predator–prey interactions and test otherwise data-deficient hypotheses. It also offers immersive insights into predator–prey interactions, making it an engaging pedagogical tool.

We explored the data to assess whether the behavior of human players reproduced ecological dynamics expected in natural systems. We found that: movements were driven by risk reward trade-offs, predators' use of linear features made them risky for prey, prey had risk-sensitive functional responses.

Functional responses of prey players when no predator is in the vicinity, in the presence of a close meso-predator, or in the presence of a close apex predator. Players gain rates saturated at high resource density and was lower when close to predators.

Non-territorial foxes avoided foraging and caching prey in areas with high encounter probability, likely to reduce cache theft In contrast, territorial foxes were less affected by encounter risk and cached prey slightly more at the edges of their territory, suggesting they don't avoid interactions

Using GPS and accelerometry data, she found that territoriality varied among individuals. Some successfully excluded neighbors from parts of their home range, while others could not. This shaped how they behaved when at risk of encountering neighbors.

Hello Bluesky! I'm a behavioral ecologist wrapping up my PhD at Laval University. I use movement data and field surveys to explore how predation shapes population dynamics and species coexistence. Most of my work is on arctic fox, shorebirds, geese and mountain goats. Happy to join the conversation!
