Three Decades of Butterfly–Plant Interaction Turnover Explained by Climate and Species Loss
Ecology Letters, Volume 29, Issue 3, March 2026.Long‐term biodiversity loss reshapes interaction dynamics inpollination networks. Communities become increasingly dominated bygeneralist species that are more capable of rewiring interactions thanspecialists. However, rewiring declines over time as species lossreduces the pool of potential partners, progressively raising thecontribution of species ...
