North Rupununi
The North Rupununi District in located in south-west Guyana consisting of a mixture of forest, savannah and wetlands ecosystems and is considered one of the most diverse areas in South America. Located on the eastern margin of the larger savannah system which extends into Brazil and is separated by the Ireng and Takutu rivers that come together to form the Rio Branco. The Guyana Rupununi system is divided into the North and South Rupununi by the Kanuku Mountains. Geology The North Rupununi is situated on the Guiana Shield, precambrian rock with a complex geology that includes plutonic, volcanic, metamorphic and sedimentary rocks and various rifting, uplifting, sedimentation and erosion events. The geology of the North Rupununi is critical because it fundamentally defines the topography, soils, hydrology and ultimately the economy of the area. The North Rupununi is part of a Mesozoic graben, the Takutu Basin. The basin is 280 kilometers long and 40 kilometers wide, is over 7 kil ...

Topography
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the landforms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically relief, even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form ( DEM). It is often considered to include the graphic representation of t ...

Kalina People
The Kalina, also known as the Caribs or mainland Caribs and by several other names, are an Indigenous people native to the northern coastal areas of South America. Today, the Kalina live largely in villages on the rivers and coasts of Venezuela, Guyana, Suriname, French Guiana, and Brazil. They speak a Cariban language known as Carib. They may be related to the Island Caribs of the Caribbean, though their languages are unrelated. Name The exonym ''Caribe'' was first recorded by Christopher Columbus. One hypothesis for the origin of ''Carib'' is that it means "brave warrior". Its variants, including the English ''Carib'', were then adopted by other European languages. Early Spanish colonizers used the terms '' Arawak'' and ''Caribs'' to distinguish the peoples of the Caribbean, with ''Carib'' reserved for Indigenous groups that they considered hostile and ''Arawak'' for groups that they considered friendly. The Kalina call themselves ''Kalina'' or ''Karìna'' , spelled vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carib Languages
The Cariban languages are a family of languages Indigenous to north-eastern South America. They are widespread across northernmost South America, from the mouth of the Amazon River to the Colombian Andes, and they are also spoken in small pockets of central Brazil. The languages of the Cariban family are relatively closely related. There are about three dozen, but most are spoken only by a few hundred people. Macushi is the only language among them with numerous speakers, estimated at 30,000. The Cariban family is well known among linguists partly because one language in the family— Hixkaryana—has a default word order of object–verb–subject. Prior to their discovery of this, linguists believed that this order did not exist in any spoken natural language. In the 16th century, Cariban peoples expanded into the Lesser Antilles. There they killed or displaced, and also mixed with the Arawak peoples who already inhabited the islands. The resulting language— Kalhíphona o ...

Wapishana
The Wapishana or Wapichan (or Wapisiana, Wapitxana, Vapidiana, Wapixana) are an Indigenous group found in the Roraima area of northern Brazil and southern Guyana. Location Currently the Wapishana are located in the State of Roraima, Brazil, northern and eastern Boa Vista, as well as in the southern Rupununi savannas of Guyana. In their villages, one can find ranches, settlements, small towns, and commercial developments of Brazilians. In Guyana, the Wapishana villages are located between the Takutu, Rupununi, and Kwitaro rivers, bordering the Macushi territory in the Kanuku Mountains to the north, and extending as far as the Wai-Wai territory to the south. In Brazilian territory, in the north eastern portion of Roraima, the Wapishana villages are mostly located in the Serra da Lua (Moon Ridge) region between the Branco River and one of its affluent, the Tacutu. On the lower Uraricoera River, another affluent of the Branco, most of the villages contain a mixed population of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amerindian
In the Americas, Indigenous peoples comprise the two continents' pre-Columbian inhabitants, as well as the ethnic groups that identify with them in the 15th century, as well as the ethnic groups that identify with the pre-Columbian population of the Americas as such. These populations exhibit significant diversity; some Indigenous peoples were historically hunter-gatherers, while others practiced agriculture and aquaculture. Various Indigenous societies developed complex social structures, including pre-contact monumental architecture, organized city, cities, city-states, chiefdoms, state (polity), states, monarchy, kingdoms, republics, confederation, confederacies, and empires. These societies possessed varying levels of knowledge in fields such as Pre-Columbian engineering in the Americas, engineering, Pre-Columbian architecture, architecture, mathematics, astronomy, History of writing, writing, physics, medicine, Pre-Columbian agriculture, agriculture, irrigation, geology, minin ...

Subsistence
A subsistence economy is an economy directed to basic subsistence (the provision of food, clothing and shelter) rather than to the market. Definition "Subsistence" is understood as supporting oneself and family at a minimum level. Basic subsistence is the provision of food, clothing, shelter. A subsistence economy is an economy directed to one's subsistence rather than to the market. Often, the subsistence economy is moneyless and relies on natural resources to provide for basic needs through hunting, gathering, and agriculture. In a subsistence economy, economic surplus is minimal and only used to trade for basic goods, and there is no industrialization. In hunting and gathering societies, resources are often, if not typically underused. The subsistence system is maintained through sharing, feasting, ritual observance and associated norms. Harvesting is an important indicator of social capital. Subsistence embodies cultural perspectives of relationships to places, people and a ...

Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment (Freshwater ecosystem, freshwater or Marine ecosystem, marine), but may also be caught from Fish stocking, stocked Body of water, bodies of water such as Fish pond, ponds, canals, park wetlands and reservoirs. Fishing techniques include trawling, Longline fishing, longlining, jigging, Fishing techniques#Hand-gathering, hand-gathering, Spearfishing, spearing, Fishing net, netting, angling, Bowfishing, shooting and Fish trap, trapping, as well as Destructive fishing practices, more destructive and often Illegal, unreported and unregulated fishing, illegal techniques such as Electrofishing, electrocution, Blast fishing, blasting and Cyanide fishing, poisoning. The term fishing broadly includes catching aquatic animals other than fish, such as crustaceans (shrimp/lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms (starfish/sea urchins).

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called pep ...

Wildlife
Wildlife refers to domestication, undomesticated animals and uncultivated plant species which can exist in their natural habitat, but has come to include all organisms that grow or live wilderness, wild in an area without being species, introduced by humans. Wildlife was also synonymous to game (hunting), game: those birds and mammals that were trophy hunting, hunted for sport. Wildlife can be found in all ecosystems. Deserts, plains, grasslands, woodlands, forests, and other areas including the most developed urban areas, all have distinct forms of wildlife. While the term in popular culture usually refers to animals that are untouched by human factors, most scientists agree that much wildlife is human impact on the environment, affected by human behavior, human activities. Some wildlife threaten human safety, health, property and quality of life. However, many wild animals, even the dangerous ones, have value to human beings. This value might be economic, educational, or emotio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethnic Group
An ethnicity or ethnic group is a group of people with shared attributes, which they collectively believe to have, and long-term endogamy. Ethnicities share attributes like language, culture, common sets of ancestry, traditions, society, religion, history or social treatment. Ethnicities may also have a narrow or broad spectrum of genetic ancestry, with some groups having mixed genetic ancestry. ''Ethnicity'' is sometimes used interchangeably with ''nation'', particularly in cases of ethnic nationalism. It is also used interchangeably with '' race'' although not all ethnicities identify as racial groups. By way of assimilation, acculturation, amalgamation, language shift, intermarriage, adoption and religious conversion, individuals or groups may over time shift from one ethnic group to another. Ethnic groups may be divided into subgroups or tribes, which over time may become separate ethnic groups themselves due to endogamy or physical isolation from the parent gr ...
