Aotidae
Night monkeys, also known as owl monkeys or douroucoulis (), are nocturnal New World monkeys of the genus ''Aotus'', the only member of the family Aotidae (). The genus comprises eleven species which are found across Panama and much of South America in primary and secondary forests, tropical rainforests and cloud forests up to . Night monkeys have large eyes which improve their vision at night, while their ears are mostly hidden, giving them their name ''Aotus'', meaning "earless". Night monkeys are the only truly nocturnal monkeys with the exception of some cathemeral populations of Azara's night monkey, who have irregular bursts of activity during day and night. They have a varied repertoire of vocalisations and live in small family groups of a mated pair and their immature offspring. Night monkeys have monochromatic vision which improves their ability to detect visual cues at night. Night monkeys are threatened by habitat loss, the pet trade, hunting for bushmeat, and by b ...

New World Monkey
New World monkeys are the five families of primates that are found in the tropical regions of Mexico, Central and South America: Callitrichidae, Cebidae, Aotidae, Pitheciidae, and Atelidae. The five families are ranked together as the Ceboidea (), the only extant superfamily in the parvorder Platyrrhini (). Platyrrhini is derived from the Greek for "broad nosed", and their noses are flatter than those of other simians, with sideways-facing nostrils. Monkeys in the family Atelidae, such as the spider monkey, are the only primates to have prehensile tails. New World monkeys' closest relatives are the other simians, the Catarrhini ("down-nosed"), comprising Old World monkeys and apes. New World monkeys descend from African simians that colonized South America, a line that split off about 40 million years ago. Evolutionary history About 40 million years ago, the Simiiformes infraorder split into the parvorders Platyrrhini (New World monkeys) and Catarrhini ( apes and Old Worl ...

Aotus Griseimembra
The gray-handed night monkey (''Aotus griseimembra'') is a species of night monkey formerly considered a subspecies of Gray-bellied night monkey of the family Aotidae. Its range consists of parts of Colombia and Venezuela. The exact classification of the gray-handed night monkey is uncertain. While some authors consider it a subspecies of the gray-bellied night monkey, ''A. lemurinus'', other authors consider it a separate species, ''A. griseimembra''. In Colombia, its range consists of the northern portion from the Sinú River (or perhaps further east) to the Venezuelan border, including the Sierra Nevada de Santa Marta and the Magdalena River, Cauca River and Sao Jorge River valleys. In Venezuela, it is found to the west and south of Maracaibo. The gray-handed night monkey is a relatively small monkey, with males weighing approximately and females weighing about . It has short, tight fur. The fur on the back ranges from grayish brown to reddish brown. The belly is ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spix's Night Monkey
Spix's night monkey (''Aotus vociferans''), also known as the Colombian gray night monkey, noisy night monkey and Spix's owl monkey, is a night monkey species from South America. It is found in Brazil, Colombia, Ecuador and Peru. The Spix's night monkey is a small bodied monkey species usually having a mass of around one kilogram. It belongs to the only nocturnal genus of New World primates Aotus. This type of monkey can leap farther than most due to it having longer arms than legs. The monkey averages 0.5 meters in height. The night monkey is considered to be a new world monkey. The social behavior of the ''Aotus vociferans'' is group based. These groups usually consist of breeding pairs and their offspring. This species has a monogamous mating system. After the offspring are born, the father becomes the main caretaker, only giving up the offspring for them to suckle. The offspring will usually stay with their birth group until they reach two and a half to three and a half years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azara's Night Monkey
Azara's night monkey (''Aotus azarae''), also known as the southern night monkey, is a night monkey species from South America. It is found in Argentina, Bolivia, Brazil, Peru and Paraguay. The species is monogamous, with the males providing a large amount of parental care. It is named after Spanish naturalist Félix de Azara. Although primarily nocturnal, some populations of Azara's night monkey are unique among night monkeys in being active both day and night. The species is listed as Least Concern on the IUCN Red List. Taxonomy There are three subspecies of Azara's night monkey. * ''Aotus azarae azarae'' * Bolivian night monkey, ''Aotus azarae boliviensis'' * Feline night monkey, ''Aotus azarae infulatus'' Physical characteristics Due to a lack of data body size and weight measurements of Azara's night monkey have been estimated from a small number of wild samples. The average head and body length of the female is while the male is . The average weight is for male ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peruvian Night Monkey
The Peruvian night monkey (''Aotus miconax''), also known as the Andean night monkey, is a nocturnal New World monkey endemic to northern Peru. Adults weigh around and measure up to in length. Its colour is grey to light brown with characteristic black and white markings on the face. The chest, belly and upper arms are orange tinged, however, to a lesser extent then '' Aotus nigriceps''. The species is one of the least known and possibly rarest Neotropical primates. This species is listed as vulnerable by the IUCN and endangered under Peruvian Law. The Peruvian night monkey is also one of the least studied of all primates. The only data that exists about this species are museum specimens, sighting records and very basic ecological information. The species is thought to inhabit areas of cloud forest at above sea level in the departments of Amazonas, Huanuco and San Martin, and in border regions of neighboring departments.

Three-striped Night Monkey
The three-striped night monkey (''Aotus trivirgatus''), also known as northern night monkey or northern owl monkey, is one of several species of owl monkeys currently recognised. It is found in Venezuela and north-central Brazil. Until 1983, all the owl monkeys were regarded as subspecies of ''Aotus trivirgatus'', and all were referred to as douroucoulis. The use of the name douroucouli exclusively for the three-striped night monkey is not universally accepted; some authors use it for the entire genus, or for the grey-necked group of species within it (to which ''A. trivirgatus'' belongs). Like other owl monkeys, the three-striped night monkey lives in woodlands including rain forest. It is mainly black, with striking white markings on its face. Its body size is 27–48 cm, and its tail is about the same length again. Adults weigh up to 1 kg. It has very large eyes, and is most active on moonlit nights, feeding on fruit, nuts, leaves, insects and other small invertebra ...

Plasmodium Falciparum
''Plasmodium falciparum'' is a unicellular protozoan parasite of humans, and the deadliest species of ''Plasmodium'' that causes malaria in humans. The parasite is transmitted through the bite of a female '' Anopheles'' mosquito and causes the disease's most dangerous form, falciparum malaria. It is responsible for around 50% of all malaria cases. ''P. falciparum'' is therefore regarded as the deadliest parasite in humans. It is also associated with the development of blood cancer (Burkitt's lymphoma) and is classified as a Group 2A (probable) carcinogen. The species originated from the malarial parasite ''Laverania'' found in gorillas, around 10,000 years ago. Alphonse Laveran was the first to identify the parasite in 1880, and named it ''Oscillaria malariae''. Ronald Ross discovered its transmission by mosquito in 1897. Giovanni Battista Grassi elucidated the complete transmission from a female anopheline mosquito to humans in 1898. In 1897, William H. Welch created the na ...

Junior Synonym
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...
