Brown Titi
The brown titi monkey (''Plecturocebus brunneus'') is a species of titi monkey, a type of New World monkey, from South America. It is endemic to Brazil. It was originally described as ''Callicebus brunneus'' in 1842 and transferred to the newly erected genus ''Plecturocebus'' in 2016. Taxonomy ''Plecturocebus'' are within a subfamily of titi called Callicebinae. Other genera included within this subfamily are the ''Cheracebus'', ''Callicebus'', and ''Plecturocebus;'' which are all still currently extant. The '' Xenothrix, Antillothrix'', ''Paralouatta, Carlocebus, Lagonimico'', and '' Tremacebus'' genera of Callicebinae are extinct. The Urubamba brown titi (''P. urubambensis'') of Peru was formerly thought to be a Peruvian population of ''P. brunneus'', but a 2015 study found it to be a distinct, undescribed species more closely related to the white-eared titi (''P. donacophilus''), and described it as such. The Brown Titi was classified as its own genus in 2016. Due to the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Zoological Park (United States)
The National Zoological Park, commonly known as the National Zoo, is one of the oldest zoos in the United States. It is part of the Smithsonian Institution and does not charge admission. Founded in 1889, its mission is to "provide engaging experiences with animals and create and share knowledge to save wildlife and habitats". The National Zoo has two campuses. The first is a urban park located at Rock Creek Park in Northwest Washington, D.C., 20 minutes from the National Mall by MetroRail. The other campus is the Smithsonian Conservation Biology Institute (SCBI; formerly known as the Conservation and Research Center) in Front Royal, Virginia. On this land, there are 180 species of trees, 850 species of woody shrubs and herbaceous plants, 40 species of grasses, and 36 different species of bamboo. The SCBI is a non-public facility devoted to training wildlife professionals in conservation biology and to propagating rare species through natural means and assisted reproduction. ...

Tremacebus
''Tremacebus'' is an extinct genus of New World monkeys from the Early Miocene (Colhuehuapian in the SALMA classification). The type species is ''T. harringtoni''. Description ''Tremacebus'' was about in length, and would have resembled a modern night monkey, to which it may have been related, though possibly a stem aotid. However, its eyes appear to have been smaller than the modern species, CT scans of the cranium suggest a relatively small olfactory bulb and poor sense of smell, compared with night monkeys. These features suggest that it may not have been nocturnal. It had an estimated body mass of . Only a few fossils have been found, including a skull from the Sarmiento Formation, Patagonia.''Tremacebus'' at |
Endemic Fauna Of Brazil
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Brazil
Brazil has the largest mammal diversity in the world, with more than 600 described species and more likely to be discovered.

Population Trend
Population growth is the increase in the number of people in a population or dispersed group. Actual global human population growth amounts to around 83 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7.9 billion in 2020. The UN projected population to keep growing, and estimates have put the total population at 8.6 billion by mid-2030, 9.8 billion by mid-2050 and 11.2 billion by 2100. However, some academics outside the UN have increasingly developed human population models that account for additional downward pressures on population growth; in such a scenario population would peak before 2100. World human population has been growing since the end of the Black Death, around the year 1350. A mix of technological advancement that improved agricultural productivity and sanitation and medical advancement that reduced mortality increased population growth. In some geographies, this has slowed through the process called the demographic tra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rondônia
Rondônia () is one of the 26 states of Brazil, located in the northern subdivision of the country (central-western part). To the west is a short border with the state of Acre, to the north is the state of Amazonas, in the east is Mato Grosso, and in the south and southwest is Bolivia. Rondônia has a population of 1,815,000 as of 2021. It is the fifth least populated state. Its capital and largest city is Porto Velho.

Monogamy
Monogamy ( ) is a form of dyadic relationship in which an individual has only one partner during their lifetime. Alternately, only one partner at any one time (serial monogamy) — as compared to the various forms of non-monogamy (e.g., polygamy or polyamory). The term is also applied to the social behavior of some animals, referring to the state of having only one mate at any one time. A monogamous relationship can be sexual or emotional, but it's usually both. Many modern relationships are monogamous. Terminology The word ''monogamy'' derives from the Greek μονός, ''monos'' ("alone"), and γάμος, ''gamos'' ("marriage").Cf. "Monogamy" in ''Britannica World Language Dictionary'', R.C. Preble (ed.), Oxford-London 1962, p. 1275:''1. The practice or principle of marrying only once. opp. to digamy now ''rare'' 2.

Viviparity
Among animals, viviparity is development of the embryo inside the body of the parent. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother. The term 'viviparity' and its adjective form 'viviparous' derive from the Latin ''vivus'' meaning "living" and ''pario'' meaning "give birth to". Reproductive mode Five modes of reproduction have been differentiated in animals based on relations between zygote and parents. The five include two nonviviparous modes: ovuliparity, with external fertilisation, and oviparity, with internal fertilisation. In the latter, the female lays zygotes as eggs with a large vitellus, yolk; this occurs in all birds, most reptiles, and some fishes. These modes are distinguished from viviparity, which covers all the modes that result in live birth: *Histotrophic viviparity: the zygotes develop in the female's oviducts, but find their nutrients b ...

Prehensility
Prehensility is the quality of an appendage or organ that has adapted for grasping or holding. The word is derived from the Latin term ''prehendere'', meaning "to grasp". The ability to grasp is likely derived from a number of different origins. The most common are tree-climbing and the need to manipulate food. Examples Appendages that can become prehensile include: Uses Prehensility affords animals a great natural advantage in manipulating their environment for feeding, climbing, digging, and defense. It enables many animals, such as primates, to use tools to complete tasks that would otherwise be impossible without highly specialized anatomy. For example, chimpanzees have the ability to use sticks to obtain termites and grubs in a manner similar to human fishing. However, not all prehensile organs are applied to tool use; the giraffe tongue, for instance, is instead used in feeding and self-cleaning Government procurement or public procurement is undertaken by the publ ...

White-eared Titi
The white-eared titi monkey (''Plecturocebus donacophilus'') also known as the Bolivian titi or Bolivian gray titi, is a species of titi monkey, a type of New World monkey, from eastern Bolivia and an area of western Brazil. The species has a range that extends east from the Manique River in Beni Department, Bolivia to southern Rondônia in Brazil. The southern end of its range includes forests around the city of Santa Cruz de la Sierra. It is a medium-sized monkey with a grey back, orange underside and distinctive white ear tufts. It has an omnivorous diet, eating fruits, other plant materials and invertebrates. It is predated upon primarily by raptors, though felids and other monkey species have been known to attack the species. It is a monogamous species and lives in small groups of two to seven members consisting of the pair and their offspring. The family group has a home range of and the adults have a complex vocal repertoire to maintain their territory. It is also kno ...
