Rupununi Savannah
The Rupununi savannah is a savanna plain in Guyana, in the Upper Takutu-Upper Essequibo region. It is part of the Guianan savanna ecoregion of the tropical and subtropical grasslands, savannas, and shrublands biome. Description The Rupununi Savannah is located between the Rupununi River and the border with Brazil and Venezuela. The Rupununi forms the southwestern wilderness territory of Guyana, a South American country situated on the Northeastern littoral of South America. The savannah is dissected by the Kanuku Mountains. The Rupununi Savannah encompasses 5000 square miles of virtually untouched grasslands, swamplands, rain-forested mountains. The region usually floods in the wet season (May to August). Early European explorers believed that the Rupununi floodplains were the legendary Lake Parime. Biodiversity The savannah is divided north from south, by the Kanuku Mountains, Guyana’s most biologically diverse region. According to Conservation International, the "area supports ...

Tropical And Subtropical Grasslands, Savannas, And Shrublands
Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. The biome is dominated by grass and/or shrubs located in semi-arid to semi- humid climate regions of subtropical and tropical latitudes. Description Grassland is dominated by grass and other herbaceous plants. Savanna is grassland with scattered trees. Shrubland is dominated by woody or herbaceous shrubs. Large expanses of land in the tropics do not receive enough rainfall to support extensive tree cover. The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between per year. Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions. Flora includes acacia and baobab trees, grass, and low shrubs. Acacia trees lose their leaves in the dry season to conserve moisture, while ...

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ...

Cassava
''Manihot esculenta'', common name, commonly called cassava (), manioc, or yuca (among numerous regional names), is a woody shrub of the spurge family, Euphorbiaceae, native to South America. Although a perennial plant, cassava is extensively cultivated as an annual agriculture, crop in tropical and subtropical regions for its edible starchy tuberous root, a major source of carbohydrates. Though it is often called ''yuca'' in parts of Spanish America and in the United States, it is not related to yucca, a shrub in the family Asparagaceae. Cassava is predominantly consumed in boiled form, but substantial quantities are used to extract cassava starch, called tapioca, which is used for food, animal feed, and industrial purposes. The Brazilian farinha, and the related ''garri'' of West Africa, is an edible coarse flour obtained by grating cassava roots, pressing moisture off the obtained grated pulp, and finally drying it (and roasting both in the case of farinha and garri). Cassav ...

Latex
Latex is an emulsion (stable dispersion) of polymer microparticles in water. Latexes are found in nature, but synthetic latexes are common as well. In nature, latex is found as a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion that coagulates on exposure to air, consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums. It is usually exuded after tissue injury. In most plants, latex is white, but some have yellow, orange, or scarlet latex. Since the 17th century, latex has been used as a term for the fluid substance in plants, deriving from the Latin word for "liquid". It serves mainly as defense against herbivorous insects. Latex is not to be confused with plant sap; it is a distinct substance, separately produced, and with different functions. The word latex is also used to refer to natural latex rubber, particularly non-vulcanized rubber. Such is the case in products like latex gloves, latex condoms ...

Manilkara Bidentata
''Manilkara bidentata'' is a species of ''Manilkara'' native to a large area of northern South America, Central America and the Caribbean. Common names include bulletwood, balatá, ausubo, massaranduba, quinilla, and (ambiguously) " cow-tree". Description The balatá is a large tree, growing to tall. The leaves are alternate, elliptical, entire, and long. The flowers are white, and are produced at the beginning of the rainy season. The fruit is a yellow berry, in diameter, which is edible; it contains one (occasionally two) seed(s). Its latex is used industrially for products such as chicle. Uses The latex is extracted in the same manner in which sap is extracted from the rubber tree. It is then dried to form an inelastic rubber-like material. It is almost identical to gutta-percha (produced from a closely related southeast Asian tree), and is sometimes called ''gutta-balatá''. Balatá was often used in the production of high-quality golf balls, to use as the outer layer of ...

Cattle Ranching
A ranch (from es, rancho/Mexican Spanish) is an area of land, including various structures, given primarily to ranching, the practice of raising grazing livestock such as cattle and sheep. It is a subtype of a farm. These terms are most often applied to livestock-raising operations in Mexico, the Western United States and Western Canada, though there are ranches in other areas.For terminologies in Australia and New Zealand, see Station (Australian agriculture) and Station (New Zealand agriculture). People who own or operate a ranch are called ranchers, cattlemen, or stockgrowers. Ranching is also a method used to raise less common livestock such as horses, elk, American bison, ostrich, emu, and alpaca.Holechek, J.L., Geli, H.M., Cibils, A.F. and Sawalhah, M.N., 2020. Climate Change, Rangelands, and Sustainability of Ranching in the Western United States. ''Sustainability'', ''12''(12), p.4942. Ranches generally consist of large areas, but may be of nearly any size. In the west ...

Wai-wai People
The Wai-wai (also written Waiwai or Wai Wai) are a Carib-speaking Indigenous people of Guyana and northern Brazil. Their society consists of different lowland forest peoples who have maintained much of their cultural identity with the exception of Christianity which was introduced to them in the late 1950s. The Umana Yana in Georgetown, Guyana, takes its name from the Wai-Wai for "meeting place". Early contact The explorer, Sir Robert Schomburgk, may have been the first western to have contact with the Wai-Wai in December 1837. He found one village on a tributary of the Essequebo river, along with two others on the Mapuera River in Brazil. Schomburgk describes the Wai-Wai as: :"''Of medium height, their skin lighter than that of Tarumas, in their general appearance and language they resemble the Makuskis a good deal. The Woyawais are great hunters and celebrated for their dogs. In appearance they are generally dirty.''" During the early 20th century, some of the Wai-Wai in Braz ...

Macushi
The Macushi ( pt, Macuxi) are an indigenous people living in the borderlands of southern Guyana, northern Brazil in the state of Roraima, and in an eastern part of Venezuela. Identification The Macushi are also known as the Macusi, Macussi, Makushi, Makusi, Makuxi, Teueia, and Teweya people. Macushi, as well as the Arecuna, Kamarakoto, and Taurepan are considered sub-groups of Pemon. Language Macushi people speak the Macushi language, a Macushi-Kapon language, which is part of the Carib language family. Some in Brazil also speak Portuguese, while some in Venezuela speak Spanish, and some in Guyana speak English. The Macushi language is written in the Latin script, and the New Testament was translated into the language in 1996. Macushi were hesitant to teach their language to outsiders, thus the language was threatened in the 1950s, as it was considered "slang" compared to the official Portuguese. Housing and lifestyle They live in villages linked together by tracks and paths, ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ...
