Tepui
A tepui , or tepuy (), is a table-top mountain or mesa found in South America, especially in Venezuela and western Guyana. The word tepui means "house of the gods" in the native tongue of the Pemon, the indigenous people who inhabit the Gran Sabana. Tepuis tend to be found as isolated entities rather than in connected ranges, which makes them the host of a unique array of endemic plant and animal species. Some of the most outstanding tepuis are Auyantepui, Autana, Neblina, and Mount Roraima. They are typically composed of sheer blocks of Precambrian quartz arenite sandstone that rise abruptly from the jungle, giving rise to spectacular natural scenery. Auyantepui is the source of Angel Falls, the world's tallest waterfall. Morphology These table-top mountains are the remains of a large sandstone plateau that once covered the granite basement complex between the north border of the Amazon Basin and the Orinoco, between the Atlantic coast and the Rio Negro.

History Spanish Colonization During the time of the Spanish Empire, it was part of the province of Nueva Andalucía and later it was annexed to the province of Guayana from 1777 when King Charles III created the Captaincy General of Venezuela. The capital of the state, Ciudad Bolivar was founded on December 21, 1595 by Antonio de Berrío, who had come from Nueva Granada (present-day Colombia) with the mission of populating Guyana. The town, originally called Santo Tomás de Guayana, was a fortified port that had to move three times, since it was the target of constant assaults by Caribbean Indians and European corsairs, among whom Sir Walter Raleigh stood out in 1617. In 1764 it foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caura National Park
The Caura National Park ( es, Parque nacional Caura) is a protected area with the status of National Park in Venezuela. With an area of 7,534,000 ha. (75,340 km2) it is the largest park in the country and the most recently created (2017). The Caura River (Venezuela), Caura River is a tributary of the Orinoco and drains an area of the Guianan Highlands moist forests. History In 1968 the government of Raúl Leoni decreed the creation of several protected spaces including forest reserves that include the Caura Area; in 2008 the government of Hugo Chávez created the Caura Plan to protect the resources of this river basin. Finally in March 2017 the administration of Nicolás Maduro decreed the creation of the Caura National Park to preserve the spaces of this extensive region between the states of Bolívar State (Venezuela), Bolívar and Amazonas State (Venezuela), Amazonas. Its first management plan was presented in March 2018. Ecosystem Flora This reserve is located in the lif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Josefa Celsa Señaris
Josefa Celsa Señaris (born 2 November 1965) is a Venezuelan herpetologist. She has published information about frogs and she has identified new genera and species. Señaris is the director of the La Salle Foundation's Natural History Museum (Spanish: ''Museo de historia natural La Salle - MhnLS'') in Caracas. Life Señaris was born in 1965 and she obtained a degree in biology at the Central University of Venezuela and her doctorate in 2001 at the University of Santiago de Compostela in Spain. She is interested in the fauna of Venezuela, in particular the Guayana Region where table-top mountains called tepuis provide habitats for endemic plant and animal species: some amphibians are known only from a single tepuy. From a geological point of view, the tepuis have been isolated for approximately 120 million years, and it has been suggested that the tepuy habitats are a "lost world" that could support relictual populations.

The IUCN Red List Of Threatened Species
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 provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
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 wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountains Of Bolívar (state)
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
