Spix's Red-handed Howler
Spix's red-handed howler (''Alouatta discolor'') is a species of Howler monkey native to the southeastern Amazon in Brazil. It is threatened by deforestation and hunting. Taxonomy The species was previously considered a subspecies of the red-handed howler, but it is now treated as a separate species. Description Spix's red-handed howler has a similar appearance to the red-handed howler, but it has a yellowish-brown to reddish-brown back. Males weigh about 7.2 kg, females about 5.5 kg. Distribution and habitat The species is endemic to central Brazil, specifically along the southeastern Amazon River in the State of Pará. It occurs mainly in the interfluvial land area between four rivers, Tapajós, Juruena, Xingú and Irirí. The westernmost limit of native habitat lies on the right bank of the Tapajós River and Juruena River and stretches east to the banks of the Xingú River and Irirí River. This strip of land extends northward to Forte Curupá ( Gurupá), Bra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Baptist Von Spix
Johann Baptist Ritter von Spix (9 February 1781 – 13 March 1826) was a German biologist. From his expedition to Brazil, he brought to Germany a large variety of specimens of plants, insects, mammals, birds, amphibians and fish. They constitute an important basis for today's National Zoological Collection in Munich. Numerous examples of his ethnographic collections, such as dance masks and the like, are now part of the collection of the Museum of Ethnography in Munich. Biography Spix was born in Höchstadt, in present-day Middle Franconia, as the seventh of eleven children. His childhood home is the site of the Spix Museum, open to the public since 2004. He studied philosophy in Bamberg and graduated with a doctoral degree. Later he studied theology in Würzburg. After attending lectures of the young professor F. W. J. Schelling, Spix became interested in nature. He quit his theology studies and began studying medicine, which he finished with a second doctoral ...

Gurupá
Gurupá or Santo Antonio de Gurupá is a municipality on the Amazon River in state of Pará, northern Brazil located near the world's largest river island, Marajó, 300 km upstream from the upper mouth of the river on the Atlantic coast. The city is a center for palm heart extraction and commerce. It is a municipal seat and major river boat port. History Gurupá is derived from the tupi language words ''guru'' (mouth) and ''pa'' (wide), and is associated with regions where water channels become wider. The word appears in the name of many localities in Brazil. Gurupá was founded in 1609 as a Dutch trading post that they called Mariocai, after the indigenous peoples living there. It was the third of three trading posts established by the Dutch along the lower reaches of the Amazon and Xingu River The Xingu River ( ; pt, Rio Xingu, ; Mẽbêngôkre: ''Byti'', ) is a river in north Brazil. It is a southeast tributary of the Amazon River and one of the largest clearwat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trans-Amazonian Highway
The Trans-Amazonian Highway (official designation BR-230, official name Rodovia Transamazônica), was introduced on September 27, 1972. It is 4,000 km long, making it the third longest highway in Brazil. It runs through the Amazon forest and the Brazilian states of Paraíba, Ceará, Piauí, Maranhão, Tocantins, Pará and Amazonas, from the proximities of Saboeiro up until the town of Lábrea. History The project was started by the military dictatorship that was in power from 1964 to 1985 out of their perceived need to guarantee control over the remote regions while encouraging economic engagement with the natural resources in the region. The highway was intended to integrate these regions with the rest of the country, and with Colombia, Peru and Ecuador. Another main goal of the project was to alleviate the effects of the drought affecting the Northeast region of the country by providing a route to largely empty land in the middle of the rainforest, which could be settled ...

Habitat Fragmentation
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats. Definition The term habitat fragmentation includes five discrete phenomena: * Reduction in the total area of the habitat * Decrease of the interior: edge ratio * Isolation of one habitat fragment from other areas of habitat * Breaking up of one patch of habitat into several smaller patches * Decrease in the average size of each patch of hab ...

Logging
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. Logging is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products. Logging systems are also used to manage forests, reduce the risk of wildfires, and restore ecosystem functions, though their efficiency for these purposes has been challenged. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities. Illegal logging refers to the harvesting, transportation, purchase, or sale of timber in violation of laws. The harvesting procedure itself may be illegal, i ...

Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wide ...

Vulnerable Species
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are 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, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. 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 is Vulnerable when it is not critically endangered or Endangered but is fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iriri River
The Iriri River ( pt, Rio Iriri, ; Mẽbêngôkre: ''Kororoti'', ) is a large tributary of the Xingu River in Brazil, in the state of Pará. It is long making it the 116th longest river in the world (with Krishna River, India) and the 15th longest in the Amazon basin. The headwaters are the traditional home of the Panará people. Course The river rises in the Nascentes da Serra do Cachimbo Biological Reserve, a strictly protected conservation unit established in 2005 in the Serra do Cachimbo. It is one of the headwaters of the Xingu River. It flows for before joining the Xingu, running through the Terra do Meio Ecological Station. The river varies greatly in volume depending on the season, and in the dry season include waterfalls, rocks and rapids. The Iriri River flows through the Tapajós–Xingu moist forests ecoregion. The river is rich in fish, including many species found only here and in the Xingu. Large sections remain unexplored due to its remoteness in a region su ...
