The Energy Cost of Bee Pollination for Pontederia cordata (Pontederiaceae)

Journal: Functional Ecology
Article Topic(s): Pollination
Research Setting(s): Wetland
Species Referenced: Pontederia cordata (Pickerelweed),
AbstractDescribes flowering, pollination, and nectar production of Pontederia cordata. This species produces 10-40 flowers per day that are only open for eight hours. Flowers produce nectar throughout the day, presumably to attract insect pollinators, although most pollen has been removed by mid-day. Pontederia cordata is pollinated by two generalist bees and one specialist bee. Nectar production throughout the day may be explained by bet-hedging in unfavorable weather conditions and to maintain the attention of generalist pollinators.
