Effects of crop and mixture identity on arthropod diversity
Observation data showed that presence of faba bean and linseed, in monoculture or mixture, lead to an increase in flower visitor diversity (Fig. 2a). Pan trap data showed that arthropod diversity was influenced by an interaction between crop mixture and management: Arthropod diversity was highest in linseed-oilseed rape mixtures, faba bean-oilseed rape mixtures and linseed monocultures under low intensity management; and in oilseed rape monocultures and wheat-faba bean-linseed mixtures under high intensity management (Fig. 2b). Both methods show that crop mixtures significantly influenced arthropod diversity (Tables S1, S2).
