Canaima National Park
Canaima National Park ( es, Parque Nacional Canaima) is a park in south-eastern Venezuela that roughly occupies the same area as the Gran Sabana region. It is located in Bolívar State, reaching the borders with Brazil and Guyana. History Canaima National Park was established on 12 June 1962. As early as 1990, the countries that participate in the Amazonian Cooperation Treaty had recommended expanding the Canaima National Park southward to connect it with Monte Roraima National Park in Brazil, with coordinated management of tourism, research and conservation. In 1994, the Canaima National Park was named a World Heritage Site by UNESCO. Location Canaima National Park is the second largest park in Venezuela, after Parima-Tapirapecó, and sixth biggest national park in the world. It is roughly the same size as Belgium or Maryland. The park protects part of the Guayanan Highlands moist forests ecoregion. About 65% of the park is occupied by plateaus of rock called tepuis, whi ...

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.

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 neighbour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarraceniaceae Of South America
''Sarraceniaceae of South America'' is a monograph on the pitcher plants of the genus ''Heliamphora'' by Stewart McPherson, Andreas Wistuba, Andreas Fleischmann, and Joachim Nerz. It was published in September 2011 by Redfern Natural History Productions and covered all species known at the time.McPherson, S., A. Wistuba, A. Fleischmann & J. Nerz 2011. ''Sarraceniaceae of South America''. Redfern Natural History Productions, Poole. The book is part of a comprehensive two-volume work on the Sarraceniaceae. The other tome, '' Sarraceniaceae of North America'', deals with the genera '' Darlingtonia'' and '' Sarracenia''. Intended as the first volume, ''Sarraceniaceae of South America'' includes an introduction to the family Sarraceniaceae as a whole. Both volumes were nominees for the 2012 CBHL Annual Literature Award, in the Technical Interest category. In addition to the main authors, others who worked on the book include Andy Smith and Wayne Jenski, who produced a number of an ...

Endemism
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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heliamphora Sp
The genus ''Heliamphora'' ( or ; Greek: ''helos'' "marsh" and ''amphoreus'' "amphora") contains 23 species of pitcher plants endemic to South America.McPherson, S., A. Wistuba, A. Fleischmann & J. Nerz 2011. ''Sarraceniaceae of South America''. Redfern Natural History Productions, Poole. The species are collectively known as sun pitchers, based on the mistaken notion that the ''heli'' of ''Heliamphora'' is from the Greek ''helios'', meaning "sun". In fact, the name derives from ''helos'', meaning marsh, so a more accurate translation of their scientific name would be marsh pitcher plants. Species in the genus ''Heliamphora'' are carnivorous plants that consist of a modified leaf form that is fused into a tubular shape. They have evolved mechanisms to attract, trap, and kill insects; and control the amount of water in the pitcher. At least one species ('' H. tatei'') produces its own proteolytic enzymes that allows it to digest its prey without the help of symbiotic bacteria. ...

Pitcher Plant
Pitcher plants are several different carnivorous plants which have modified leaves known as pitfall traps—a prey-trapping mechanism featuring a deep cavity filled with digestive liquid. The traps of what are considered to be "true" pitcher plants are formed by specialized leaves. The plants attract and drown their prey with nectar. Types The term "pitcher plant" generally refers to members of the Nepenthaceae and Sarraceniaceae families, but similar pitfall traps are employed by the monotypic Cephalotaceae and some members of the Bromeliaceae. The families Nepenthaceae and Sarraceniaceae are the most species-rich families of pitcher plants. The Nepenthaceae contains a single genus, ''Nepenthes'', containing over 100 species and numerous hybrids and cultivars. In this genus of Old World pitcher plants, the pitchers are borne at the end of tendrils that extend from the midrib of an otherwise unexceptional leaf. Old World pitcher plants are typically characterized as having r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undescribed Taxon
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a '' nomen nudum''. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published. An undescribed species may be referred to with the genus name, followed by "sp"., but this abbreviation is also used to label specimens or images that are too incomplete to be identified at the species level. In some cases, there is more than one undescribed species in a genus. In this ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominated by shrubs, often also including grasses, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high and usually with many stems. Tall shrubs are mostly 2–8 m high, small shrubs 1–2 m high an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
