The Cerro Duida region of Venezuela. ''Geographical Review'' 20(1): 31–52. Cerro Duida shares a common base with the much smaller (but taller) Cerro Marahuaca, located off its northeastern flank, and together they form the Duida–Marahuaca Massif.

Tepuis Of Venezuela
A tepui , or tepuy (), is a member of a family of table-top mountains or mesas found in northern South America, especially in Venezuela, western Guyana, and northern Brazil. 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. Notable tepuis include Auyantepui, Autana, Neblina, and Mount Roraima. They are typically composed of sheer blocks of Precambrian quartz arenite sandstone that rise abruptly from the jungle. 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. This area is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach th ....

Distribution Of Heliamphora
The natural range of the carnivorous plant genus ''Heliamphora'' is restricted to the southern Venezuelan states of Amazonas, Venezuela, Amazonas and Bolívar, Venezuela, 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, western range in Amazonas and the #Eastern range, 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 ...

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 large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dischidodactylus Duidensis
Mount Duida frogs (''Dischidodactylus'') form a genus of brachycephaloid frogs endemic to the tepuis of southern Venezuela. The scientific name is derived from the Greek ''dischidos'', meaning divided, and ''dactylos'', meaning finger or toe, in reference to the divided ungual flap (see below). Taxonomy The family in which ''Dischidodactylus'' should be placed is currently uncertain. Amphibian Species of the World currently places it in superfamily Brachycephaloidea with family incertae sedis, while AmphibiaWeb places it in Ceuthomantidae. It had been placed in subfamily Ceuthomantinae within family Craugastoridae based on morphology because no DNA sequence data was available. ''Dischidodactylus'' was considered closely related to ''Ceuthomantis'' because they share a synapomorphy (completely or almost completely divided ungual flaps) and both genera also have dorsal skin composed of small, flat, pliable (not keratinized) warts, and lack nuptial pads in adult males; they differ ...
