Nectar robbing and plant reproduction: an interplay of positive and negative effects

Number of pollen tubes at three distances from stiles producing after cross-hand pollination, and single visits of nectar robbers (<i>Bombus terrestris</i> and <i>Xylocopa vioacea</i>). Visit rates of legitimate visitors in response to visits by nectar robbers and flowers per plant.

本数据集包含两类统计内容：一是人工异花授粉后，距花柱三个不同距离处的花粉管数量，以及盗蜜者——地熊蜂（Bombus terrestris）与紫木蜂（Xylocopa vioacea）——的单次访花次数；二是响应盗蜜者访花的合法传粉者访花频率，以及单株植株的花朵数量。
