Vavilovian mimicry (also known as crop mimicry or weed mimicry [31]) is named after the Russian plant geneticist who identified the centres of origin of cultivated plants, Nikolai Vavilov. [8] It is a form of mimicry in plants where a weed comes to share one or more characteristics with a domesticated plant through generations of unintentional ...
The form of mimicry in plants that deceives an insect into pseudocopulation is called Pouyannian mimicry after the French lawyer and amateur botanist Maurice-Alexandre Pouyanne. A non-mimetic form of pseudocopulation has been observed in some parthenogenetic, all-female species of lizard. The behaviour does not appear to be necessary to trigger ...
Mimicry is an evolved resemblance between an organism and another object, often an organism of another species. Mimicry may evolve between different species, or between individuals of the same species. Often, mimicry functions to protect from predators. [11] Mimicry systems have three basic roles: a mimic, a model, and a dupe.
Cryptic mimicry is observed in animals as well as plants. In animals, this may involve nocturnality, camouflage, subterranean lifestyle, and mimicry. Generally, plant herbivores are visually oriented. [1] [2] So a mimicking plant should strongly resemble its host; this can be done through visual and/or textural change. Previous criteria for ...
Aggressive mimicry stands in semantic contrast with defensive mimicry, where it is the prey that acts as a mimic, with predators being duped. Defensive mimicry includes the well-known Batesian and Müllerian forms of mimicry, where the mimic shares outward characteristics with an aposematic or harmful model. In Batesian mimicry, the mimic is ...
The gold-of-pleasure or false flax resembles flax, and its seeds are practically inseparable from the flax seed.. In plant biology and agriculture, Vavilovian mimicry (also crop mimicry or weed mimicry [1]) is a form of mimicry in plants where a weed evolves to share characteristics with a crop plant through generations of involuntary artificial selection.
Complicated forms of aggressive mimicry have also been observed in fish, creating a system that resembles Batesian mimicry. The false cleanerfish , Aspidontus taeniatus , is a fin-eating blenny that has evolved to resemble a local species of cleaner wrasse, Labroides dimidiatus , which engages in mutualistic cleaning with larger fish.
In ecology, crypsis is the ability of an animal or a plant [1] to avoid observation or detection by other animals. It may be part of a predation strategy or an antipredator adaptation. Methods include camouflage, nocturnality, subterranean lifestyle and mimicry. Crypsis can involve visual, olfactory (with pheromones) or auditory concealment.
