Tree diversity increases robustness of multi-trophic interactions

Multi-trophic interactions maintain critical ecosystem functions. Biodiversity is declining globally, while responses of trophic interactions to biodiversity change are largely unclear. Thus, studying responses of multi-trophic interaction robustness to biodiversity change is crucial for understanding ecosystem functioning and persistence. We investigate plant–Hemiptera (antagonism) and Hemiptera–ant (mutualism) interaction networks in response...
