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 ...
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.
Non-vascular plants , with their different evolutionary background, tend to have separate terminology. Although plant morphology (the external form) is integrated with plant anatomy (the internal form), the former became the basis of the taxonomic description of plants that exists today, due to the few tools required to observe.

Giant axons of the longfin inshore squid (Doryteuthis pealeii) were crucial for scientists to understand the action potential. [1]Biomimetics or biomimicry is the emulation of the models, systems, and elements of nature for the purpose of solving complex human problems.
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 existence of automimicry in the form of non-toxic mimics of toxic members of the same species (analogous to Batesian mimicry [5]) poses two challenges to evolutionary theory: how can automimicry be maintained, and how can it evolve? For the first question, as long as prey of the species are, on average, unprofitable for predators to attack ...
