We tested the removal effect on nectar production in four bat-pollinated cerrado flowers. We compared the amount of nectar after 7–12 removals with the accumulated nectar in non-manipulated flowers after 12 h. In all, but one species, removals increased volume by 1.5–4.6 times and sugar content by 1.6–4 times, which may affect flower visitation by bats, pollen flow, and reproduction.
