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 ...
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. It is named after the Russian plant geneticist Nikolai Vavilov.
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 ...
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.
By contrast, a leaf-mimicking plant, the chameleon vine, employs Batesian mimicry by adapting its leaf shape and colour to match that of its host to deter herbivores from eating its edible leaves. [13] Another analogous case within a single species has been termed Browerian mimicry [3] (after Lincoln P. Brower and Jane Van Zandt Brower [14] [15]).
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 ...

Pseudocopulation by an insect on a flower is a result of Pouyannian mimicry, named after the French lawyer and amateur botanist Maurice-Alexandre Pouyanne. . [1] [2] This occurs in several orchids, whose flowers mimic the female mating signals of specific pollinator insects, such as bees. [3]
