چکیده

Whitney et al. (Reports, 2 January 2009, p. 130) investigated the mechanism of iridescence in hibiscus and tulip flowers and suggested that bumblebees are able to use this iridescence as a pollination cue. However, their study failed to isolate iridescence from other coincident visual cues, leaving open questions regarding the importance of iridescent stimuli in foraging-based associative learning in bumblebees.

Is floral iridescence a biologically relevant cue in plant-pollinator signaling?

Flowers allure potential pollinators by displaying attractive colour patterns, which are generally created by their petal arrangement and pigmentation. In addition to the pigmentary coloration, in certain cases reflecting surface structures may contribute to the flowers' appearance. For instance, a flower petal surface with periodic striations, acting as a grating reflector, can create an angle...

Flower Iridescence Increases Object Detection in the Insect Visual System without Compromising Object Identity

Iridescence is a form of structural coloration, produced by a range of structures, in which hue is dependent on viewing angle [1-4]. One of these structures, the diffraction grating, is found both in animals (for example, beetles [2]) and in plants (on the petals of some animal pollinated flowers [5]). The behavioral impacts of floral iridescence and its potential ecological significance are un...

اپتیک عدسی داخل چشمی چند کانونی تفرقی

The diffractive multifocal IOL provides simultaneous bifocal imaging by utilizing both diffractive and refractive optics. In both distant and near vision, there is a clear highly focused image on the retina. The second image is highly defocused, providing only faint background illumination. A small amount of the light goes to the higher orders of diffraction which are not perceptible by eyes. T...

Floral Symmetry and Its Role in Plant-Pollinator Systems.

Floral symmetry has a relevant status in the study of both pollination biology and animal behavior. In this work, a brief review and classification of symmetry types in flowers is provided as a basis for understanding the role of floral symmetry in pollination phenomena. We focus on insects as a fundamental group of pollinators, and we discuss symmetry from the perspective of insect perception....
