Night Monkey
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, although some cathemeral populations of Azara's night monkey 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 biomedical resear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panamanian Night Monkey
The Panamanian night monkey or Chocoan night monkey (''Aotus zonalis'') is a species of night monkey formerly considered a subspecies of the gray-bellied night monkey of the family Aotidae. Its range consists of Panama and the Chocó region of Colombia. There are also unconfirmed reports of its occurrence in Costa Rica, especially on the Caribbean coast of Costa Rica. The species definitely occurs in the Atlantic lowlands of Panama close to the Costa Rica border. The exact classification of the Panamanian Night Monkey is uncertain. While some authors consider it a subspecies of the gray-bellied night monkey, ''A. lemurinus'', other authors follow a study by Thomas Defler from 2001, which concluded that it is a separate species, ''A. zonalis''. The Panamanian night monkey is a relatively small monkey, with males weighing approximately and females weighing about . The fur on the back ranges from grayish brown to reddish brown. The belly is yellow. The hair on the back o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protozoan
Protozoa (: protozoan or protozoon; alternative plural: protozoans) are a polyphyletic group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic debris. Historically, protozoans were regarded as "one-celled animals". When first introduced by Georg Goldfuss, in 1818, the taxon Protozoa was erected as a class within the Animalia, with the word 'protozoa' meaning "first animals", because they often possess animal-like behaviours, such as motility and predation, and lack a cell wall, as found in plants and many algae. This classification remained widespread in the 19th and early 20th century, and even became elevated to a variety of higher ranks, including phylum, subkingdom, kingdom, and then sometimes included within the paraphyletic Protoctista or Protista. By the 1970s, it became usual to require that all taxa be monophyletic (derived from a common ancestor that would also be regarded as protozo ...

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 .

Black-headed Night Monkey
The black-headed night monkey (''Aotus nigriceps'') is a night monkey species from South America. It is found in Brazil, Bolivia and Peru. The ''A. nigriceps'' in Peru were notably inhabiting areas that were degraded, and often these areas were disturbed either by human activities or natural occurrences in the ecosystem. A black-headed night monkey is about the same size as a small squirrel. Black-headed night monkeys have small ears that are hidden by their fur. When they become adults they are about 750g and usually are about 14 months old. Black-headed night monkeys have three black stripes that meet on their forehead. These monkeys have white patches by their eyes, cheeks, and under their mouth. Their eyes are very large and brown. Reproduction A newborn usually weighs about 90 to 150g. Sexual maturity for males is at 2 years and for females is about 3 or 4 years. They occur in between August and February. A female only gives birth to one infant each year. The males are the ...

Nancy Ma's Night Monkey
Nancy Ma's night monkey (''Aotus nancymaae'') is a night monkey species from South America. It is found in Brazil and Peru. The species is named after Dr. Nancy Shui-Fong Ma. It is known in medical research as a model organism for studying the Duffy antigen Duffy antigen/chemokine receptor (DARC), also known as Fy glycoprotein (FY) or CD234 (Cluster of Differentiation 234), is a protein that in humans is encoded by the ''ACKR1'' gene. The Duffy antigen is located on the surface of red blood cells, .... Nancy Ma's night monkeys have also been found to have an evolutionary pattern change in the hormone oxytocin. It was believed that all placental mammals had the same OXT amino acid chain until the discovery of a change in this New World monkey and others.

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 hal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Junior Synonym
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. 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, ...

Least-concern Species
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. In 2012 there were 5,196 animals and 6,789 plants classified as vulnerable, compared with 2,815 and 3,222, respectively, in 1998. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A taxon ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, invasive species, and climate change. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct.
