Ecology and Evolution, Volume 15, Issue 12, December 2025.Camponotus lateralis (C, D) mimics regional color morphs of Crematogaster (A, B). Field trips brought insights into ecology, trail sharing, sexual reproduction, colony foundation, nest defense, and predation pressure of this mimetic ant. We found that the mimicry is Batesian and suggest several preadaptations for its evolution.

Functional Ecology, Volume 39, Issue 12, Page 3446-3458, December 2025.Abstract Elton's biotic resistance hypothesis suggests that diverse communities are more resistant to biological invasions. While below‐ground mechanisms play a crucial role in regulating the diversity–invasibility relationship, the role of litter as a key regulator of below‐ground processes remains underexplored. We used 15 common native plant species
