Comment on "Floral iridescence, produced by diffractive optics, acts as a cue for animal pollinators".
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 learn...
متن کاملIs 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...
متن کاملFlower 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...
متن کاملThe diversity of floral temperature patterns, and their use by pollinators
Pollinating insects utilise various sensory cues to identify and learn rewarding flower species. One such cue is floral temperature, created by captured sunlight or plant thermogenesis. Bumblebees, honeybees and stingless bees can distinguish flowers based on differences in overall temperature between flowers. We report here that floral temperature often differs between different parts of the f...
متن کاملاپتیک 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...
