Researchers from the University of Florence and University of Pisa conducted an experiment demonstrating that managed honeybees (Apis mellifera) on Giannutri Island significantly deplete nectar and pollen availability, leading to around an 80% decline in wild bee populations. Results provide strong causal evidence that honeybee competition, rather than environmental change, is responsible for wild bee decline.
