Cacajao Ayresi
Uakari (, ) is the common name for the New World monkeys of the genus ''Cacajao''. Both the English and scientific names are believed to have originated from indigenous languages. The uakaris are unusual among New World monkeys in that the tail length (15–18 cm) is substantially less than their head and body length (40–45 cm). Their bodies are covered with long, loose hair but their heads are bald. They have almost no subcutaneous fat, so their bald faces appear almost skull-like. Like their closest relatives the saki monkeys, they have projecting lower incisors. These monkeys have the most striking red facial skin of any primate. Females choose their mates based on how red the male's face is. Evidence suggests that the red facial coloration reflects the health of the primate. The uakari is one of the least known monkeys in South America. The four species of uakari currently recognized are all found in the north-western Amazon basin. The bald uakari, remarkable for ...

Bald Uakari
The bald uakari (''Cacajao calvus'') or bald-headed uakari is a small New World monkey characterized by a very short tail; bright, crimson face; a bald head; and long coat. The bald uakari is restricted to várzea forests and other wooded habitats near water in the western Amazon of Brazil and Peru. Taxonomy There are four recognized subspecies of the bald uakari, each of which is considered vulnerable to extinction: * White bald-headed uakari, ''Cacajao calvus calvus'' * Ucayali bald-headed uakari, ''Cacajao calvus ucayalii'' * Red bald-headed uakari, ''Cacajao calvus rubicundus'' * Novae's bald-headed uakari, ''Cacajao calvus novaesi'' Description The bald uakari weighs between 2.75 and 3.45 kg (6.1 and 7.6 lb), with head and body lengths average 45.6 cm (18.0 in) (male) and 44.0 cm (17.3 in) (female).

Colombia
Colombia (, ; ), officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments and the Capital District of Bogotá, the country's largest city. It covers an area of 1,141,748 square kilometers (440,831 sq mi), and has a population of 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Amerindian civilizations that predate colonization.

Riparian
A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin '' ripa'', meaning " river bank". Characteristics Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important natural b ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Amazon Biome
The Amazon biome ( pt, Bioma Amazônia) contains the Amazon rainforest, an area of tropical rainforest, and other ecoregions that cover most of the Amazon basin and some adjacent areas to the north and east. The biome contains blackwater and whitewater flooded forest, lowland and montane terra firma forest, bamboo and palm forest, savanna, sandy heath and alpine tundra. Some areas are threatened by deforestation for timber and to make way for pasture or soybean plantations. Location The Amazon biome has an area of . The biome roughly corresponds to the Amazon basin, but excludes areas of the Andes to the west and cerrado (savannah) to the south, and includes lands to the northeast extending to the Atlantic ocean with similar vegetation to the Amazon basin. J. J. Morrone (2006) defines the Amazonian subregion in this broader sense, divided into the biogeographical provinces of Guyana, Humid Guyana, Napo, Imeri, Roraima, Amapá, Várzea, Ucayali, Madeira, Tapajós-Xingu, Pará, Yun ...

Frugivory
A frugivore is an animal that thrives mostly on raw fruits or succulent fruit-like produce of plants such as roots, shoots, nuts and seeds. Approximately 20% of mammalian herbivores eat fruit. Frugivores are highly dependent on the abundance and nutritional composition of fruits. Frugivores can benefit or hinder fruit-producing plants by either dispersing or destroying their seeds through digestion. When both the fruit-producing plant and the frugivore benefit by fruit-eating behavior the interaction is a form of mutualism. Frugivore seed dispersal Seed dispersal is important for plants because it allows their progeny to move away from their parents over time. The advantages of seed dispersal may have led to the evolution of fleshy fruits, which entice animals to consume them and move the plant's seeds from place to place. While many fruit-producing plant species would not disperse far without frugivores, their seeds can usually germinate even if they fall to the ground directl ...

Aracá Uakari
The Aracá uakari (''Cacajao ayresi''), also known as the Ayres black uakari, is a newly described species of monkey from the northwest Brazilian Amazon. It was found by Jean-Phillipe Boubli of the University of Auckland after following native Yanomamo Indians on their hunts along the Rio Aracá, a northern tributary of the Rio Negro. It was subsequently described in 2008 together with the more westerly distributed Neblina uakari. Until then, the black-headed uakari was the only species of mainly black uakari that was recognized. Stephen F. Ferrari ''et al'' proposed treating the Aracá uakari as a subspecies of the black-headed uakari rather than as a separate species. This monkey is named after Brazilian biologist José Márcio Ayres, formerly a senior zoologist for the Wildlife Conservation Society. José Márcio Ayres, who died in 2003, pioneered studies in uakaris and played a fundamental role in the creation of the Mamirauá Sustainable Development Reserve, which is of ...

Casiquiare Canal
The Casiquiare river () is a distributary of the upper Orinoco flowing southward into the Rio Negro, in Venezuela, South America. As such, it forms a unique natural canal between the Orinoco and Amazon river systems. It is the world's largest river of the kind that links two major river systems, a so-called bifurcation. The area forms a water divide, more dramatically at regional flood stage. Etymology The name ''Casiquiare'', first used in that form by Manuel Román, likely derives from the Ye'kuana language name of the river, ''Kashishiwadi''. Discovery In 1744 a Jesuit priest named Manuel Román, while ascending the Orinoco River in the region of La Esmeralda, met some Portuguese slave-traders from the settlements on the Rio Negro. The Portuguese insisted they were not in Spanish territory but on a tributary of the Amazon; they invited Román back with them to prove their claim. He accompanied them on their return, by way of the Casiquiare canal, and afterwards retraced h ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Neblina Uakari
The Neblina uakari (''Cacajao hosomi'') or black-headed uakari, is a newly described species of monkey from the far northwest Brazilian Amazon and adjacent southern Venezuela. It was found by Jean-Phillipe Boubli of the University of Auckland and described together with the more easterly distributed Aracá uakari in 2008. Until then, the black-headed uakari (found to the west and south of the Neblina uakari) was the only species of mainly black uakari that was recognized. The English name of the Neblina uakari refers to the Pico da Neblina, which marks the approximate center of its known distribution. Several years before it was realized it represented an undescribed species (and not "just" black-headed uakaris), it was studied in the Pico da Neblina National Park in Brazil. When combined with the adjacent Serranía de la Neblina National Park in Venezuela, a significant part of this uakaris distribution is within protected areas. It has well coordinated travel established thro ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rio Negro (Amazon)
The Rio Negro ( pt, Rio Negro, br ; es, Río Negro} "''Black River''"), or Guainía as it is known in its upper part, is the largest left tributary of the Amazon River (accounting for about 14% of the water in the Amazon basin), the largest blackwater river in the world, and one of the world's ten largest rivers by average discharge. Geography Upper course The source of the Rio Negro lies in Colombia, in the Department of Guainía where the river is known as the ''Guainía River''. The young river generally flows in an east-northeasterly direction through the Puinawai National Reserve, passing several small indigenous settlements on its way, such as Cuarinuma, Brujas, Santa Rosa and Tabaquén. After roughly 400 km the river starts forming the border between Colombia's Department of Guainía and Venezuela's Amazonas State. After passing the Colombian community of Tonina and Macanal the river turns Southwest. Maroa is the first Venezuelan town the river passes. 1 ...

Black-headed Uakari
The golden-backed uakari (''Cacajao melanocephalus'') or black-headed uakari, is a New World primate from the family Pitheciidae. It lives in the Amazon Rainforest, and is found in the countries of Brazil, Colombia, and Venezuela. It has black hair covering its body, except for a reddish abdomen, tail, and upper limbs, and a bald face. It has highly specialised teeth which allow it to eat seeds and fruits with hard shells. The name golden-backed uakari is a neotype proposed by Boubli ''et al.'' (2008). Taxonomy The species ''Cacajao melanocephalus'' was previously named the black-headed uakari and two subspecies were thought to exist: ''Cacajao melanocephalus melanocephalus'' (black-backed uakari) and ''Cacajao melanocephalus ouakary'' (golden-backed uakari).Hershkovitz, P.
