Sexual Mimicry
Sexual mimicry occurs when one sex mimics the opposite sex in its behavior, appearance, or chemical signalling. It is more commonly seen within invertebrate species, although sexual mimicry is also seen among vertebrates such as spotted hyenas. Sexual mimicry is commonly used as a mating strategy to gain access to a mate, a defense mechanism to avoid more dominance (ethology), dominant individuals, or a survival strategy. It can also be a physical characteristic that establishes an individual's place in society. Sexual mimicry is employed differently across species and it is part of their strategy for survival and reproduction. Examples of intraspecific sexual mimicry in animals include the spotted hyena, certain types of fish, passerine birds and some species of insect. Interspecific sexual mimicry can also occur in some plant species, especially orchids. In plants employing sexual mimicry, flowers mimic mating signals of their pollinator insects. These insects are attracted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominance (ethology)
In the zoological field of ethology, a dominance hierarchy (formerly and colloquially called a pecking order) is a type of social hierarchy that arises when members of animal social groups interact, creating a ranking system. Different types of interactions can result in dominance depending on the species, including ritualized displays of aggression or direct physical violence. In social living groups, members are likely to compete for access to limited resources and mating opportunities. Rather than fighting each time they meet, individuals of the same sex establish a relative rank, with higher-ranking individuals often gaining more access to resources and mates. Based on repetitive interactions, a social order is created that is subject to change each time a dominant animal is challenged by a subordinate one. Definitions Dominance is an individual's preferential access to resources over another based on coercive capacity based on strength, threat, and intimidation, comp ...

Salaria Pavo
{{Blen ...
''Salaria pavo'', the peacock blenny, is a species of combtooth blenny found in the eastern Atlantic coast from France to Morocco; also in the Mediterranean Sea, Black Sea and the eastern Adriatic Sea. This species has colonised the northern Red Sea by anti-Lessepsian migration through the Suez Canal. The peacock blenny reaches a length of TL. The peacock blenny have unique reproductive behaviors. Bourgeois males typically build and guard nests. Sneaker males will mimic female behaviors in order to approach nests and fertilize eggs.

Honest Signalling
Within evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species. The central question is how organisms with conflicting interests, such as in sexual selection, are expected to provide honest signals rather than deceive or cheat, given that the passing on of pleiotropic traits is subject to natural selection, which aims to minimize associated costs without assuming any conscious intent. Mathematical models describe how signalling can contribute to an evolutionarily stable strategy. Signals are given in contexts such as mate selection by females, which subjects the advertising males' signals to selective pressure. Signals thus evolve because they modify the behaviour of the receiver to benefit the signaller. Signals may be honest, conveying information which usefully increases the fitness of the receiver, or dishonest. An individual can cheat by giving a dishonest signal, which migh ...

European Pied Flycatcher
The European pied flycatcher (''Ficedula hypoleuca'') is a small passerine bird in the Old World flycatcher family. One of the four species of Western Palearctic black-and-white flycatchers, it bird hybrid, hybridises to a limited extent with the collared flycatcher. It breeds in most of Europe and across the Western Palearctic. It is migratory, wintering mainly in tropical Africa. It usually builds its nests in holes on oak trees. This species practices Polygyny in animals, polygyny, usually bigamy, with the male travelling large distances to acquire a second mate. The male will mate with the secondary female and then return to the primary female in order to help with aspects of child rearing, such as feeding. The European pied flycatcher is mainly insectivorous, although its diet also includes other arthropods. This species commonly feeds on caterpillars, flies, spiders, ants, bees and similar prey. The European pied flycatcher has a very large range and population size and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ficedula Hypoleuca Sussex 8
The ''Ficedula'' flycatchers are a genus of Old World flycatchers. The genus is the largest in the family, containing around thirty species. They have sometimes been included in the genus ''Muscicapa''. The genus is found in Europe, Asia and Africa. Several species are highly migratory, whereas other species are sedentary.

Dark-edged Splitfin
The dark-edged splitfin (''Girardinichthys multiradiatus'') is a species of fish in the family Goodeidae endemic to Mexico Mexico, officially the United Mexican States, is a country in North America. It is the northernmost country in Latin America, and borders the United States to the north, and Guatemala and Belize to the southeast; while having maritime boundar .... It is a live-bearing, cold-water fish from the mountains of Mexico. The species is incredibly temperature sensitive. If water is too cold, all offspring turn out to be male. If water is too hot, females will birth their first brood of only 1–3 fry and then die shortly thereafter, which makes it very difficult to maintain a colony. It is also a primarily carnivorous species that eats a variety of insects. ''Girardinichtys multiradiatus'' is an endangered species with multiple population threats with little conservation efforts put in place to protect the species.
