Supernormal Stimulus as a Mimicry Strategy: the case for Epidendrum radicans (Orchidaceae)
Epidendrum radicans is a food deceptive Batesian mimic of its sympatric model species Asclepias curassavica and Lantana camara. Theoretically, food deceptive orchids should be rare with small inflorescences (Johnson et al. 1993; Weins 1978) yet in San Luis, Costa Rica E. radicans grows in large monotypic stands with individuals sporting up to 12 open flowers per inflorescence. E. radicans might...
متن کاملFork-tailed drongos use deceptive mimicked alarm calls to steal food.
Despite the prevalence of vocal mimicry in animals, few functions for this behaviour have been shown. I propose a novel hypothesis that false mimicked alarm calls could be used deceptively to scare other species and steal their food. Studies have previously suggested that animals use their own species-specific alarm calls to steal food. However none have shown conclusively that these false alar...
متن کاملEffects of individual and population parameters on reproductive success in three sexually deceptive orchid species.
Reproductive success (RS) in orchids in general, and in non-rewarding species specifically, is extremely low. RS is pollinator and pollination limited in food deceptive orchids, but this has rarely been studied in sexually deceptive orchid species. Here, we tested the effects of several individual (plant height, inflorescence size, nearest neighbour distance and flower position) and population ...
متن کاملThe betrayed thief – the extraordinary strategy of Aristolochia rotunda to deceive its pollinators
Pollination of several angiosperms is based on deceit. In such systems, the flowers advertise a reward that ultimately is not provided. We report on a previously unknown pollination/mimicry system discovered in deceptive Aristolochia rotunda (Aristolochiaceae). Pollinators were collected in the natural habitat and identified. Flower scent and the volatiles of insects (models) potentially mimick...
متن کاملFloral evolution as a figment of the imagination of pollinators.
Schaefer and Ruxton recently reviewed the mechanisms involved in plant deception, with an emphasis on pollination [1]. They proposed that generalised food deception evolves if plants exploit the innate preferences of pollinators, and thus represents a form of exploitation of perceptual biases (EPB). They contrast this with floral mimicry, which is viewed as a distinct phenomenon that might orig...
