e/Pollinator exclusion experiment

Information
has gloss	eng: Pollinator exclusion experiments are experiments used by ecologists to determine the effectiveness of putative plant pollination vectors. Essentially, certain pollinators are prevented from visiting certain flowers, and observations are then made on the which flowers develop seeds. If the exclusion of a certain class of visitor prevents or greatly reduces flower fertilisation rates, then it can be concluded that that class of visitor plays an important role in pollination.
