La Esmeralda, Venezuela
La Esmeralda (Ye'kuana: or Moreira, Maria Geralda de Almeida (2005) ''Em busca do território perdido: o reconhecimento daterra indígena Kaxarari no Brasil e da terra Ye'kuana do Alto Orinoco na Venezuela (1970-1002)'', page 158) is a small settlement in and the capital of Alto Orinoco Municipality in Venezuela’s Amazonas State. The name means “the emerald”. It is located on the shore of the Orinoco river, only 9 miles from the Casiquiare canal bifurcation that links it to the Amazon River. The settlement contains about a hundred homes, a school, an airfield and a military outpost.

Amazon Basin
The Amazon basin is the part of South America drained by the Amazon River and its tributaries. The Amazon drainage basin covers an area of about , or about 35.5 percent of the South American continent. It is located in the countries of Bolivia, Brazil, Colombia, Ecuador, Guyana, Peru, Suriname, and Venezuela. Most of the basin is covered by the Amazon rainforest, also known as Amazonia. With a area of dense tropical forest, this is the largest rainforest in the world. Geography The Amazon River begins in the Andes Mountains at the west of the basin with its main tributary the Marañón River and Apurimac River in Peru. The highest point in the watershed of the Amazon is the second biggest peak of Yerupajá at . With a length of about before it drains into the Atlantic Ocean, it is one of the two longest rivers in the world. A team of scientists has claimed that the Amazon is longer than the Nile, but debate about its exact length continues. The Amazon system ...

Tepuis Of Venezuela
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.

Duida Grass Finch
The Duida grass finch (''Emberizoides duidae'') is a species of bird in the family Thraupidae. It is endemic to Cerro Duida, a mountain in Venezuela, and is known only from specimens collected in 1928 and 1929. The population is nevertheless believed to be stable because of the remoteness of its range. Its natural habitat is dry savanna A savanna or savannah is a mixed woodland- grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to ....

Distribution Of Heliamphora
The natural range of the carnivorous plant genus ''Heliamphora'' is restricted to the southern Venezuelan states of Amazonas and Bolívar, and to adjacent portions of northern Brazil and western Guyana, an area corresponding to the western part of the Guayana Shield. These plants are largely confined to the summits and foothills of the sandstone table-top mountains of the region, known as ''tepuis''. The genus has a highly disjunct distribution spread across two major groups of tepuis: the western range in Amazonas and the eastern range in Bolívar.Rice, B. (2012)''Heliamphora'': the various ranges and tepuis The Carnivorous Plant FAQ. The western range can be further subdivided into two complexes of neighbouring tepuis. The more southerly of these consists of Cerro de la Neblina, Cerro Aracamuni, and Cerro Avispa, and supports four ''Heliamphora'' species. The more northerly group of the western range, home to only two species, includes the massive Cerro Duida and neighbou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bassett Maguire
Bassett Maguire (August 4, 1904 – February 6, 1991) was an American botanist, head curator of the New York Botanical Garden, and a leader of scientific expeditions to the Guyana Highlands in Brazil and Venezuela. Life Maguire was born in Gadsden, Alabama, on August 4, 1904. He obtained his doctorate from Cornell University in 1938. In 1931, he was appointed assistant professor of botany at Utah State University, where he started the Intermountain Herbarium and served as its principal collector and curator until 1942.

Henry Gleason
Henry Allan Gleason (1882–1975) was an American ecologist, botanist, and taxonomist. He was known for his endorsement of the individualistic or open community concept of ecological succession, and his opposition to Frederic Clements's concept of the climax state of an ecosystem. His ideas were largely dismissed during his working life, leading him to move into plant taxonomy, but found favour late in the twentieth century. Life and work Gleason was born in Dalton City, Illinois, and after undergraduate and master's work at the University of Illinois earned a PhD from Columbia University in Biology in 1906. He held faculty positions at the University of Illinois, the University of Chicago and the University of Michigan, before returning to the East Coast, to the New York Botanical Garden in the Bronx, New York, where he remained for the rest of his career, until 1950. In Gleason's early ecological research on the vegetation of Illinois, around 1909-1912, he worked largely wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dischidodactylus Duidensis
''Dischidodactylus duidensis'' (common name: Mount Duida frog) is a species of frog in the family Craugastoridae. It is endemic to Venezuela and only known from its type locality, Cerro Duida. It was formally described in 1968 by Juan A. Rivero, even though the type series was collected 40 years earlier by George Henry Hamilton Tate. Description The type series consists of four specimens: the holotype, a female in snout–vent length (SVL), and paratypes, a male and a female both SVL, and a juvenile SVL. Skin is roughly granular and very dark, almost black above, and greyish brown below. Snout is rounded. Tympanum is small and indistinct. Fingers are free but toes are about one-third webbed. Habitat and conservation ''Dischidodactylus duidensis'' were collected by G. H. H. Tate from near waterfalls and streams on Cerro Duida at elevations of asl American Sign Language (ASL) is a natural language that serves as the predominant sign language of Deaf communities in ...
