Cotingo River
The Cotingo River ( pt, Rio Cotingo) is a river of Roraima state in northern Brazil, a tributary of the Surumu River. It flows through the Raposa Serra do Sol indigenous territory. For many years there has been discussion over building a major hydroelectric power project on the river. River basin The Cotingo River has its headwaters at the foot of Mount Roraima in the Guayana Highlands region. The upper part of the Cotingo River basin is contained in the Monte Roraima National Park, a protected area created in 1989 that is fully contained in the Raposa Serra do Sol indigenous territory. The river runs for about to its confluence with the Surumu River, of which is the main tributary. It contains continuous stretches of rapids and waterfalls. The savanna region of the river basin has an equatorial climate with tropical monsoon rainfall. Conservation It is home to the Sun parakeet (Aratinga solstitialis), Rio Branco antbird (Cercomacra carbonaria), Finsch's euphonia (Euph ...

Roraima
Roraima (, ) is one of the 26 states of Brazil. Located in the country's North Region, it is the northernmost and most geographically and logistically isolated state in Brazil. It is bordered by the state of Pará to the southeast, Amazonas to the south and west, Venezuela to the north and northwest, and Guyana to the east. The state covers an area of approximately , slightly larger than Belarus, being the fourteenth largest Brazilian state by area. The city of Boa Vista is the capital and largest city in the state, and is the only capital in the country located entirely in the Northern Hemisphere. Antônio Denarium, a member of the conservative Progressistas party, has been the governor of the state since 2019. Roraima is the least populous state in Brazil, with an estimated population of 631,181 inhabitants as of 2020. It is also the state with the lowest population density in Brazil, with 2.01 inhabitants per square kilometre. Its economy, based mainly on the tertia ...

The Rio Branco antbird (''Cercomacra carbonaria'') is a bird species in the family Thamnophilidae. It is found in Brazil ( Roraima) and Guyana. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist shrubland. It is severely threatened by habitat loss. The Rio Branco antbird was described by the English ornithologists Philip Sclater and Osbert Salvin in 1873 and given its current binomial name ''Cercomacra carbonaria''.

Solar Power
Solar power is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often to drive a steam turbine. Photovoltaics were initially solely used as a source of electricity for small and medium-sized applications, from the calculator powered by a single solar cell to remote homes powered by an off-grid rooftop PV system. Commercial concentrated solar power plants were first developed in the 1980s. Since then, as the cost of solar electricity has fallen, grid-connected solar PV systems have grown more or less exponentially. Millions of installations and gigawatt-scale photovoltaic power stations continue to be built, with half of new generation capacity being solar in ...

Wind Power
Wind power or wind energy is mostly the use of wind turbines to generate electricity. Wind power is a popular, sustainable, renewable energy source that has a much smaller impact on the environment than burning fossil fuels. Historically, wind power has been used in sails, windmills and windpumps but today it is mostly used to generate electricity. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission network. New onshore (on-land) wind farms are cheaper than new coal or gas plants, but expansion of wind power is being hindered by fossil fuel subsidies. Onshore wind farms have a greater visual impact on the landscape than some other power stations. Small onshore wind farms can feed some energy into the grid or provide power to isolated off-grid locations. Offshore wind farms deliver more energy per installed capacity with less fluctuations and have less visual impact. Although there is less offshore wind power ...

Branco River
The Branco River ( pt, Rio Branco; Engl: ''White River'') is the principal affluent of the Rio Negro from the north. Basin The river drains the Guayanan Highlands moist forests ecoregion. It is enriched by many streams from the Tepui highlands which separate Venezuela and Guyana from Brazil. Its two upper main tributaries are the Uraricoera and the Takutu. The latter almost links its sources with those of the Essequibo; during floods headwaters of the Branco and those of the Essequibo are connected, allowing a level of exchange in the aquatic fauna (such as fish) between the two systems. The Branco flows nearly south, and finds its way into the Negro through several channels and a chain of lagoons similar to those of the latter river. It is long, up to its Uraricoera confluence. It has numerous islands, and, above its mouth, it is broken by a bad series of rapids. Water chemistry As suggested by its name, the Branco (literally "white" in Portuguese) has whitish water that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecotourism
Ecotourism is a form of tourism involving responsible travel (using sustainable transport) to natural areas, conserving the environment, and improving the well-being of the local people. Its purpose may be to educate the traveler, to provide funds for ecological conservation, to directly benefit the economic development and political empowerment of local communities, or to foster respect for different cultures and for human rights. Since the 1980s, ecotourism has been considered a critical endeavor by environmentalists, so that future generations may experience destinations relatively untouched by human intervention. Ecotourism may focus on educating travelers on local environments and natural surroundings with an eye to ecological conservation. Some include in the definition of ecotourism the effort to produce economic opportunities that make conservation of natural resources financially possible. Generally, ecotourism deals with interaction with biotic components of the na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoary-throated Spinetail
The hoary-throated spinetail (''Synallaxis kollari'') is a Critically Endangered bird species in the Furnariinae subfamily of the ovenbird family Furnariidae. It is found in Brazil and Guyana.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, G. Del-Rio, A. Jaramillo, D. F. Lane, M. B. Robbins, F. G. Stiles, and K. J. Zimmer. Version 26 November 2023. Species Lists of Birds for South American Countries and Territories. https://www.museum.lsu.edu/~Remsen/SACCCountryLists.htm retrieved November 27, 2023 Taxonomy and systematics The hoary-throated spinetail was originally described in genus ''Synallaxis''. In the early twentieth century some authors moved it into the newly created genus ''Poecilurus''. By 2000 the merger of ''Poecilurus'' into ''Synallaxis'' was generally accepted and a study published in 2011 confirmed that placement. That study also established that the hoary-throated spinetail is a sister species to the white-whiskered spinetail (''S. candei'') an ...

Sun Parakeet
The sun parakeet (''Aratinga solstitialis''), also known in aviculture as the sun conure, is a medium-sized, vibrantly colored parrot native to northeastern South America. The adult male and female are similar in appearance, with black beaks, predominantly golden-yellow plumage, orange-flushed underparts and face, and green and blue-tipped wings and tails. Sun parakeets are very social birds, typically living in flocks. They form monogamous pairs for reproduction, and nest in palm cavities in the tropics. Sun parakeets mainly feed on fruits, flowers, berries, blossoms, seeds, nuts, and insects. Conures are commonly bred and kept in aviculture and may live up to 30 years. This species is currently threatened by loss of habitat and trapping for plumage or the pet trade. Sun parakeets are now listed as endangered by the IUCN (International Union for Conservation of Nature). Taxonomy The sun parakeet was one of the many species originally described by Carl Linnaeus in his landmark 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
