Most relationships between nectar attributes for flowers and plants on successive days were non-significant. Nearby flowers were positively correlated for all attributes, except log(fructose/glucose) as fructose≈glucose. To evaluate potential attraction of repeat-visits to flowers or plants through nectar, we compared attributes between successive days. To evaluate potential pollinator manipulation through nectar, we analysed relationships between neighbouring flowers for nectar volume, concentration, proportion sucrose, log(fructose/glucose), and sugar weight. We measured nectar volume, concentration and sugar composition for open flowers on naturally-growing Blandfordia grandiflora plants, presenting classic bird-pollinated plant syndrome. Plant potential to manipulate pollinators depends on relationships between neighbouring flowers within plants, for all nectar attributes, but this has not been investigated. Such relationships should result from evolutionary games, with plants and pollinators adopting Evolutionarily Stable Strategies, and nectar manipulating rather than attracting pollinators. For example, floral nectars for vertebrate-pollinated plants average low sugar concentrations, while such animals prefer high concentrations, perplexing pollination biologists and arousing recent controversy.

Beth Botts, Chicago Tribune, 16 July 2023 Most frogs are carnivores, but after finding plant matter in X. USA TODAY, 28 June 2023 Both common rose mallow and swamp rose mallow attract bees, including the specialist pollinator rose mallow bee, as well as offering nectar to hummingbirds and butterflies. Jesús Rodríguez, Washington Post, 24 July 2023 According to Smithsonian Magazine, bees have an enzyme in their stomachs called glucose oxidase, which mixes with nectar and breaks down into gluconic acid and hydrogen peroxide. 2023 In Washington, Democratic control of the Senate and the White House makes support for such bills merely culture-war nectar for conservative hard-liners, for the time being. Arricca Elin Sansone, Country Living, 8 Aug. 2023 Because about 90 percent of their diet is sugary nectar, putting out hummingbird food in a feeder is a great way to provide a supplementary source of nutrition for these aerial acrobats, especially during nesting and migration times in the spring and fall. 2023 Fortunately, there are numerous late-season nectar sources, though most are sun-loving species.
