Bumblebees utilize floral cues differently on vertically and horizontally arranged flowers [Behavioral Ecology]

by Frédéric Magné - published on , updated on

Pollinators have the capability of discriminating a wide variety of floral cues in order to identify rewarding flowers. However, little is known about how possible ecological or functional implications of horizontal and vertical positioning of flowers affect pollinator decision making. Flowers are commonly either arranged horizontally in meadows or vertically in inflorescences and blooming trees or bushes. Using bumblebees (Bombus terrestris), we here investigate if these 2 different foraging scenarios affect decision-making accuracy using an operant learning paradigm.(...)
