 We also evaluate the effects of the landscape structure on the pollination, and demonstrate that it exists an optimal size of natural habitat patches which maximize the pollination service for a fixed fraction of natural habitat . Finally, we reveal the effect of the distinct ways of mixing culture on the number of visits to the crop .
