Moriche
''Mauritia flexuosa'', known as the moriche palm, ''ité'' palm, ''ita'', ''buriti'', ''muriti'', ''miriti'' (Brazil), ''canangucho'' (Colombia), ''acho'' (Ecuador), or ''aguaje'' (Peru), is a palm tree. It grows in and near swamps and other wet areas in tropical South America. ''Mauritia flexuosa'', a tree, can reach up to in height. The large leaves form a rounded crown. The flowers are yellowish and appear from December to April. The fruit, which grows from December to June, is a chestnut color and is covered with shiny scales. The yellow flesh covers a hard, oval nut. The seeds float, and this is the means by which the palm tree propagates. In natural populations, the tree reaches very high densities. Fruit Moriche palm fruit ("morete" in the Oriente of Ecuador) is edible and used to make juice, jam, ice cream, a fermented "wine", desserts and snacks, requiring harvesting of more than 50 tonnes per day in Peru. The inflorescence buds are eaten as a vegetable and the sap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moriche Oriole
The 'moriche oriole'' (''Icterus cayanensis chrysocephalus'') is a passerine bird in the New World family Icteridae. It is unrelated to Old World orioles (family Oriolidae). It is a breeding resident in the tropics of eastern South America. This bird is noted for its close association with the palm ''Mauritia flexuosa'' (moriche, buriti, ita, ité, etc.). This ecologically distinct bird was formerly treated as a species ''Icteruchrysocephalus'. It was eventually found to be embedded in the epaulet oriole (''I. cayanensis'') clade. Thus, for example the AOU since 2005 has lumped the moriche oriole into ''I. cayanensis''. The subspecific structure of ''I. cayanensis'' is still rather puzzling. This is a slim bird, long and weighing , with a long tail and thin decurved bill. It has mainly black plumage, apart from a bright yellow crown, rump, thighs and wing epaulets. The sexes are similar, but the juvenile bird is dark brown rather than black, with duller yellow patches. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-bellied Macaw
The red-bellied macaw (''Orthopsittaca manilatus''), also known as ''Guacamaya Manilata'', is a medium-sized, mostly green South American parrot, a member of a group of large Neotropical parrots known as macaws. It is the largest of what are commonly called " mini-macaws". The belly has a large maroon patch which gives the species its name. It is endemic to tropical Amazonian South America, from Colombia and Trinidad south to Amazonian Peru and Bolivia, and central Brazil as far as the northwestern cerrado. Its habitat is moriche (or buriti) palm (''Mauritia flexuosa'') swamp forests and sandy savannahs with palm groves. They are critically dependent on the Moriche palm for roosting, feeding and nesting. Although the bird is locally common, in places it has been adversely affected by clearing of the palms for use as posts, or to allow cattle ranching; also by capture for the pet trade. Not to be confused with the African red-bellied parrot (''Poicephalus rufiventris''), a si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulphury Flycatcher
The sulphury flycatcher (''Tyrannopsis sulphurea'') is a passerine bird which is a localised resident breeder from Trinidad, the Guianas and Venezuela south to Amazonian Peru, northern Bolivia and Brazil. This large tyrant flycatcher is found in savannah habitat with moriche palms. The nest is an open cup of sticks in the crown of a moriche palm, and the typical clutch is two cream-coloured eggs blotched with brown. The adult sulphury flycatcher is 20.3 cm long and weighs 54g. The head and neck are dark grey, and there is a concealed yellow crown stripe. The upperparts are olive, and the wings and tail are brown. The underparts are yellow with a greenish tint to the upper breast and a white throat. The black bill is short and broad. This species resembles the tropical kingbird, but is shorter, stockier, and has a shorter bill. The call is a loud squealing ''jweeez'', quite different from the kingbird's twittering. Sulphury flycatchers wait on an exposed perch high in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Llanos
The Llanos ( Spanish ''Los Llanos'', "The Plains"; ) is a vast tropical grassland plain situated to the east of the Andes in Colombia and Venezuela, in northwestern South America. It is an ecoregion of the tropical and subtropical grasslands, savannas, and shrublands biome. Geography The Llanos occupy a lowland that extends mostly east and west. The Llanos are bounded on the west and northwest by the Andes, and on the north by the Venezuelan Coastal Range. The Guiana Highlands are to the southeast, and the Negro-Branco moist forests are to the southwest. To the east the Orinoco wetlands and Orinoco Delta swamp forests occupy the Orinoco Delta. The Llanos' main river is the Orinoco, which runs from west to east through the ecoregion and forms part of the border between Colombia and Venezuela. The Orinoco is the major river system of Venezuela. Climate The ecoregion has a tropical savanna climate that grades into a tropical monsoon climate in the Colombian Llanos. Rainfa ...

Carolus Linnaeus The Younger
Carl Linnaeus the Younger, Carolus Linnaeus the Younger, Carl von Linné den yngre (Swedish; abbreviated Carl von Linné d. y.), or ''Linnaeus filius'' (Latin for ''Linnaeus the son''; abbreviated L.fil. (outdated) or L.f. (modern) as a botanical authority; 20 January 1741 – 1 November 1783) was a Swedish naturalist. His names distinguish him from his father, the pioneering taxonomist Carl Linnaeus (1707–1778). Biography Carl Linnaeus the Younger was enrolled at the University of Uppsala at the age of nine and was taught science by his father's students, including Pehr Löfling, Daniel Solander, and Johan Peter Falk. In 1763, aged just 22, he succeeded his father as the head of Practical Medicine at Uppsala. His promotion to professor — without taking exams or defending a thesis — caused resentment among his colleagues. His work was modest in comparison to that of his father. His best-known work is the ''Supplementum Plantarum systematis vegetabilium'' of 1781 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brasília
Brasília (; ) is the federal capital of Brazil and seat of government of the Federal District. The city is located at the top of the Brazilian highlands in the country's Central-West region. It was founded by President Juscelino Kubitschek on 21 April 1960, to serve as the new national capital. Brasília is estimated to be Brazil's third-most populous city. Among major Latin American cities, it has the highest GDP per capita. Brasília was a planned city developed by Lúcio Costa, Oscar Niemeyer and Joaquim Cardozo in 1956 in a scheme to move the capital from Rio de Janeiro to a more central location. The landscape architect was Roberto Burle Marx. The city's design divides it into numbered blocks as well as sectors for specified activities, such as the Hotel Sector, the Banking Sector, and the Embassy Sector. Brasília was inscribed as a UNESCO World Heritage Site in 1987 due to its modernist architecture and uniquely artistic urban planning. It was named "Cit ...

States Of Brazil
The federative units of Brazil ( pt, unidades federativas do Brasil) are subnational entities with a certain degree of autonomy (self-government, self-regulation and self-collection) and endowed with their own government and constitution, which together form the Federative Republic of Brazil. There are 26 states (') and one federal district ('). The states are generally based on historical, conventional borders which have developed over time. The states are divided into municipalities, while the Federal District assumes the competences of both a state and a municipality. Government The government of each state of Brazil is divided into executive, legislative and judiciary branches. The state executive branch is headed by a state governor and includes a vice governor, both elected by the citizens of the state. The governor appoints several secretaries of state (each one in charge of a given portfolio) and the state attorney-general. The state legislative branch is the legi ...

Federal District (Brazil)
The Federal District ( pt, Distrito Federal ) is one of 27 federative units of Brazil. Located in the Center-West Region, it is the smallest Brazilian federal unit and the only one that has no municipalities, being divided into 31 administrative regions. The federal capital of Brazil, Brasília, which is also the seat of government of the Federal District, is located in its territory. History From the first republican constitution there was already a device that foresaw the move of the federal capital from Rio de Janeiro, at that time in the former Federal District (1889-1960), to the interior of the country. In 1891 the Exploration Commission of the Central Highlands of Brazil was appointed, led by astronomer Luiz Cruls and composed of doctors, geologists and botanists, who made a study on topography, climate, geology, flora, fauna and other material resources of the region of the Central Highlands The area was known as Quadrilateral Cruls and was presented in 1894 to t ...

Robert T
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including English, German, Dutch, Norwegian, Swedish, Scots, Danish, and Icelandic. It can ...

Keystone Species
A keystone species is a species which has a disproportionately large effect on its natural environment relative to its abundance, a concept introduced in 1969 by the zoologist Robert T. Paine. Keystone species play a critical role in maintaining the structure of an ecological community, affecting many other organisms in an ecosystem and helping to determine the types and numbers of various other species in the community. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. Some keystone species, such as the wolf, are also apex predators. The role that a keystone species plays in its ecosystem is analogous to the role of a keystone in an arch. While the keystone is under the least pressure of any of the stones in an arch, the arch still collapses without it. Similarly, an ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measures of biomass o ...

Alexander Von Humboldt
Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography. Humboldt's advocacy of long-term systematic geophysical measurement laid the foundation for modern geomagnetic and meteorological monitoring. Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a modern Western scientific point of view. His description of the journey was written up and published in several volumes over 21 years. Humboldt was one of the first people to propose that the lands bordering the Atlantic Ocean were once joined (South America and Africa in particular). Humboldt resurrected t ...
