structure and functionality of plant-pollinator networks." Sci Rep
9(1): 4711.<br>
The honeybee is the primary managed species worldwide for both
crop pollination and honey production. Owing to beekeeping
activity, its high relative abundance potentially affects the
structure and functioning of pollination networks in natural
ecosystems. Given that evidences about beekeeping impacts are
restricted to observational studies of specific species and
theoretical simulations, we still lack experimental data to test
for their larger-scale impacts on biodiversity. Here we used a
three-year field experiment in a natural ecosystem to compare the
effects of pre- and post-establishment stages of beehives on the
pollination network structure and plant reproductive success. Our
results show that beekeeping reduces the diversity of wild
pollinators and interaction links in the pollination networks. It
disrupts their hierarchical structural organization causing the
loss of interactions by generalist species, and also impairs
pollination services by wild pollinators through reducing the
reproductive success of those plant species highly visited by
honeybees. High-density beekeeping in natural areas appears to
have lasting, more serious negative impacts on biodiversity than
was previously assumed.<br>
