Description
Mooij and four co-authors ask in 2026 why triangles abound in real networks. In webs of competing species, three-way loops show up far more than plain random models predict. Past answers invoked direct loop-closing rules or geometry.
The team offers a fresh idea: stable coexistence itself may favor triangles. In equal-strength competition models, they prove bounds on when species can all persist, set by the busiest node's links. Tuning networks while holding link counts fixed, they found stronger stable networks always had more clustering. Real grassland plant webs also showed more clustering and stability than shuffled versions, backing the idea.
