Campanulotes
''Campanulotes'' is a genus of lice in the disputed, probably paraphyletic, family Philopteridae, the chewing lice, or in the family Goniodidae. It is mostly a genus of parasites on birds. Some species in the genus may have been cases of coextinction. The species ''Campanulotes defectus'' was thought to have been unique to the passenger pigeon (''Ectopistes migratorius''), an extinct bird from North America, but is now believed to have been a case of a contaminated specimen, as the species is considered to be the still-extant '' Campanulotes flavus'' of Australia. Known species of ectoparasites of the common rock dove include ''Campanulotes bidentatus ''Campanulotes'' is a genus of lice in the disputed, probably paraphyletic, family Philopteridae, the chewing lice, or in the family Goniodidae.

Passenger Pigeon
The passenger pigeon or wild pigeon (''Ectopistes migratorius'') is an extinct species of pigeon that was endemic to North America. Its common name is derived from the French word ''passager'', meaning "passing by", due to the migratory habits of the species. The scientific name also refers to its migratory characteristics. The morphologically similar mourning dove (''Zenaida macroura'') was long thought to be its closest relative, and the two were at times confused, but genetic analysis has shown that the genus '' Patagioenas'' is more closely related to it than the ''Zenaida'' doves. The passenger pigeon was sexually dimorphic in size and coloration. The male was in length, mainly gray on the upperparts, lighter on the underparts, with iridescent bronze feathers on the neck, and black spots on the wings. The female was , and was duller and browner than the male overall. The juvenile was similar to the female, but without iridescence. It mainly inhabited the deciduous fore ...

Coextinction
Coextinction and cothreatened refer to the phenomena of the loss or decline of a host species resulting in the loss or endangerment of an other species that depends on it, potentially leading to cascading effects across trophic levels. The term originated by the authors Stork and Lyal (1993) and was originally used to explain the extinction of parasitic insects following the loss of their specific hosts. The term is now used to describe the loss of any interacting species, including competition with their counterpart, and specialist herbivores with their food source. Coextinction is especially common when a keystone species goes extinct. Causes The most frequently cited example is that of the extinct passenger pigeon and its parasitic bird lice ''Columbicola extinctus'' and ''Campanulotes defectus''. Recently, ''C. extinctus'' was rediscovered on the band-tailed pigeon, and ''C. defectus'' was found to be a likely case of misidentification of the existing ''Campanulotes fl ...

Rock Dove
The rock dove, rock pigeon, or common pigeon ( also ; ''Columba livia'') is a member of the bird family Columbidae (doves and pigeons). In common usage, it is often simply referred to as the "pigeon". The domestic pigeon (''Columba livia domestica'', which includes about 1,000 different breeds) descended from this species. Escaped domestic pigeons have increased the populations of feral pigeons around the world. Wild rock doves are pale grey with two black bars on each wing, whereas domestic and feral pigeons vary in colour and pattern. Few differences are seen between males and females. The species is generally monogamous, with two squabs (young) per brood. Both parents care for the young for a time. Habitats include various open and semi-open environments. Cliffs and rock ledges are used for roosting and breeding in the wild. Originally found wild in Europe, North Africa, and western Asia, pigeons have become established in cities around the world. The species is abundant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S Kéler
S, or s, is the nineteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Origin Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a phoneme, so the derived Greek letter sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ) "to hiss". The original name of the letter "sigma" may have been ''san'', but due to the complic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
