Mimicry & Deception in Pollination

چکیده

Dafni, A. 1983. Pollination of Orchis caspia – a nectarless plant which deceives the pollinators of nectariferous species from other plant families. Journal of Ecology 71: 467-474. In this study of the title species, Dafni contributes to basic knowledge about the nature of deceptive pollination systems and introduces the ideas of pollinators finding it hard to distinguish between a mimic and a model; the lack of nectar in this assumed mimic; as well as the notion that this type of pollination is not the result of co-evolution, per se, but rather evolution of pollinator exploitation by the orchid.

Pre-adaptations and the evolution of pollination by sexual deception: Cope's rule of specialization revisited.

Pollination by sexual deception is arguably one of the most unusual liaisons linking plants and insects, and perhaps the most illustrative example of extreme floral specialization in angiosperms. While considerable progress has been made in understanding the floral traits involved in sexual deception, less is known about how this remarkable mimicry system might have arisen, the role of pre-adap...

Deception in plants: mimicry or perceptual exploitation?

Mimicry involves adaptive resemblance between a mimic and a model. However, despite much recent research, it remains contentious in plants. Here, we review recent progress on studying deception by flowers, distinguishing between plants relying on mimicry to achieve pollination and those relying on the exploitation of the perceptual biases of animals. We disclose fundamental differences between ...

Orchid sexual deceit provokes ejaculation.

Sexually deceptive orchids lure pollinators by mimicking female insects. Male insects fooled into gripping or copulating with orchids unwittingly transfer the pollinia. The effect of deception on pollinators has been considered negligible, but we show that pollinators may suffer considerable costs. Insects pollinating Australian tongue orchids (Cryptostylis species) frequently ejaculate and was...

A Deceptive Pollination System Targeting Drosophilids through Olfactory Mimicry of Yeast

In deceptive pollination, insects are bamboozled into performing nonrewarded pollination. A prerequisite for the evolutionary stability in such systems is that the plants manage to generate a perfect sensory impression of a desirable object in the insect nervous system [1]. The study of these plants can provide important insights into sensory preference of their visiting insects. Here, we prese...

Mechanisms and evolution of deceptive pollination in orchids.

The orchid family is renowned for its enormous diversity of pollination mechanisms and unusually high occurrence of non-rewarding flowers compared to other plant families. The mechanisms of deception in orchids include generalized food deception, food-deceptive floral mimicry, brood-site imitation, shelter imitation, pseudoantagonism, rendezvous attraction and sexual deception. Generalized food...
