Dendrobates Variabilis
''Ranitomeya variabilis'', formerly known as ''Dendrodates variabilis'', is a species of small poison dart frog distributed in northern Peru, along the eastern slope of Anes in the upper Rio Huallaga drainage basin. Its common name, Zimmerman’s poison frog, is named after Elke Zimmermann, a German zoologist who described the morph of this species and differentiated it from '' D. Ventrimaculatus''. The species was formerly considered to be synonymous with '' Ranitomeya ventrimaculata''. ''Ranitomeya variabilis'' usually has a bright yellow body with deep blue limbs, and black spotted or stripes across the ventral side of the body. The colors change in some geographic locations. ''R. variabilis'' has different mimicry relationships with two other species. Like other frogs in the same family, ''R. variabilis'' has toxic skin alkaloid which repels potential predators. ''R. variabilis'' are cannibalistic even as tadpoles, so adult male parents may allow tadpoles to jump on their ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Promiscuity
Promiscuity is the practice of engaging in sexual activity frequently with different Sexual partner, partners or being indiscriminate in the choice of sexual partners. The term can carry a moral judgment. A common example of behavior viewed as promiscuous by many cultures is the one-night stand, and its frequency is used by researchers as a marker for promiscuity. What sexual behavior is considered promiscuous varies between cultures, as does the prevalence of promiscuity. Different standards are often applied to different genders and civil statutes. Feminism, Feminists have traditionally argued a significant double standard exists between how men and women are judged for promiscuity. Historically, stereotypes of the promiscuous woman have tended to be pejorative, such as "the slut" or "the harlot", while male stereotypes have been more varied, some expressing approval, such as "the stud" or "the player", while others imply societal deviance, such as "the womanizer" or "the philand ...

Poison Dart Frogs
Poison dart frog (also known as dart-poison frog, poison frog or formerly known as poison arrow frog) is the common name of a group of frogs in the family Dendrobatidae which are native to tropical Central and South America. These species are diurnal and often have brightly colored bodies. This bright coloration is correlated with the toxicity of the species, making them aposematic. Some species of the family Dendrobatidae exhibit extremely bright coloration along with high toxicity, while others have cryptic coloration with minimal to no amount of observed toxicity. The species that have great toxicity derive this feature from their diet of ants, mites and termites. However, other species that exhibit cryptic coloration, and low to no amounts of toxicity, eat a much larger variety of prey. Many species of this family are threatened due to human infrastructure encroaching on their habitats. These amphibians are often called "dart frogs" due to the Native Americans' use of the ...

Müllerian Mimicry
Müllerian mimicry is a natural phenomenon in which two or more well-defended species, often foul-tasting and sharing common predators, have come to mimic each other's honest warning signals, to their mutual benefit. The benefit to Müllerian mimics is that predators only need one unpleasant encounter with one member of a set of Müllerian mimics, and thereafter avoid all similar coloration, whether or not it belongs to the same species as the initial encounter. It is named after the German naturalist Fritz Müller, who first proposed the concept in 1878, supporting his theory with the first mathematical model of frequency-dependent selection, one of the first such models anywhere in biology. Müllerian mimicry was first identified in tropical butterflies that shared colourful wing patterns, but it is found in many groups of insects such as bumblebees, and other animals including poison frogs and coral snakes. The mimicry need not be visual; for example, many snakes share a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Batesian Mimicry
Batesian mimicry is a form of mimicry where a harmless species has evolved to imitate the warning signals of a harmful species directed at a predator of them both. It is named after the English naturalist Henry Walter Bates, after his work on butterflies in the rainforests of Brazil. Batesian mimicry is the most commonly known and widely studied of mimicry complexes, such that the word mimicry is often treated as synonymous with Batesian mimicry. There are many other forms however, some very similar in principle, others far separated. It is often contrasted with Müllerian mimicry, a form of mutually beneficial convergence between two or more harmful species. However, because the mimic may have a degree of protection itself, the distinction is not absolute. It can also be contrasted with functionally different forms of mimicry. Perhaps the sharpest contrast here is with aggressive mimicry where a predator or parasite mimics a harmless species, avoiding detection and improving its ...

Mimicry
In evolutionary biology, 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 a species from predators, making it an anti-predator adaptation. Mimicry evolves if a receiver (such as a predator) perceives the similarity between a mimic (the organism that has a resemblance) and a model (the organism it resembles) and as a result changes its behaviour in a way that provides a selective advantage to the mimic. The resemblances that evolve in mimicry can be visual, acoustic, chemical, tactile, or electric, or combinations of these sensory modalities. Mimicry may be to the advantage of both organisms that share a resemblance, in which case it is a form of mutualism; or mimicry can be to the detriment of one, making it parasitic or competitive. The evolutionary convergence between groups is driven by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ranitomeya Vanzolinii
''Ranitomeya vanzolinii'', also known as the Brazilian poison frog or spotted poison frog, is a species of frog from the family Dendrobatidae. It is found in the Amazonian rainforests of Brazil and Peru, and possibly Bolivia. Etymology The specific name ''vanzolinii'' honors Paulo Vanzolini, a Brazilian herpetologist and composer. Description Adults of this species grow to between snout–vent length and feed on a variety of tiny invertebrates. During the breeding season males have loud trill-like call. Unlike many species of dendrobatids the parents of ''Ranitomeya vanzolinii'' offspring return to feed their young. They will lay their fertile egg in an isolated pool. A bromeliad which has filled with water is an ideal place. Once the tadpole hatches the female encouraged by the male will lay an infertile egg into the small pool, this provides the tadpole with a food source until it can fend for itself. The parents form a stable pair during this period. Habitat and conservation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mimic Poison Frog
''Ranitomeya imitator'' ( formerly ''Dendrobates imitator''), is a species of poison dart frog found in the north-central region of eastern Peru. Its common names include mimic poison frog and poison arrow frog, and it is one of the best known dart frogs.J.L. Brown, E.

Dieffenbachia
''Dieffenbachia'' , commonly known as dumb cane or leopard lily, is a genus of tropical flowering plants in the family Araceae. It is native to the New World Tropics from Mexico and the West Indies south to Argentina. Some species are widely cultivated as ornamental plants, especially as houseplants, and have become naturalized on a few tropical islands. ''Dieffenbachia'' is a perennial herbaceous plant with straight stem, simple and alternate leaves containing white spots and flecks, making it attractive as indoor foliage. Species in this genus are popular as houseplants because of their tolerance of shade. The English names, dumb cane and mother-in-law's tongue (also used for ''Sansevieria'' species) refer to the poisoning effect of raphides, which can cause temporary inability to speak. ''Dieffenbachia'' was named by Heinrich Wilhelm Schott, director of the Botanical Gardens in Vienna, to honor his head gardener Joseph Dieffenbach (1796–1863). Species The World Checklist ...
