A Direct Measure of Pollinator Effectiveness
Oecologia, . V. 57. No. 1/2. P. 196199 (4).
A direct measure of pollinator effectiveness, relying on seed set, is proposed, where: PEi = (PiZ) / (UZ). Pi = mean number of seeds set / flower by a plant population receiving a single visit from species i. Z = mean number of seeds set / flower by a population receiving no visitation. U = mean number of seeds set / flower by a population receiving unrestrained visitation. The utility and limitations of the proposed measure are discussed and exemplified with a population of Ipomoea trichocarpa (Convoculaceae).
