in comparisons of integrated and conventional farm management. In contrast, when organic and conventional farming systems were compared, plants (n = 36) and birds (n = 24) were more commonly reported than any invertebrate functional group. Pollinator studies were reported far more frequently in comparisons between organic and conventional farming systems (n = 13) than in integrated farming systems (n = 2). There were very few studies of farming system and invertebrate food for farmland birds.
