Rio De Janeiro Botanical Garden
The Rio de Janeiro Botanical Garden or Jardim Botânico is located at the Jardim Botânico district in the South Zone of Rio de Janeiro. The Botanical Garden shows the diversity of Brazilian and foreign flora. There are around 6,500 species (some endangered) distributed throughout an area of as well as numerous greenhouses. The garden also houses monuments of historical, artistic, and archaeological significance. There is an important research center, which includes the most complete library in the country specializing in botany with over 32,000 volumes. It was founded in 1808 by King John VI of Portugal. Originally intended for the acclimatization of spices like nutmeg, pepper and cinnamon imported from the West Indies, the garden was opened to the public in 1822, and is now open during daylight hours every day except 25 December and 1 January. The park lies at the foot of the Corcovado Mountain, far below the right arm of the statue of '' Christ the Redeemer'' and contains ...

Rio De Janeiro
Rio de Janeiro ( , , ; literally 'River of January'), or simply Rio, is the capital of the state of the same name, Brazil's third-most populous state, and the second-most populous city in Brazil, after São Paulo. Listed by the GaWC as a beta global city, Rio de Janeiro is the sixth-most populous city in the Americas. Part of the city has been designated as a World Heritage Site, named "Rio de Janeiro: Carioca Landscapes between the Mountain and the Sea", on 1 July 2012 as a Cultural Landscape.

Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spines, ...

Roystonea Oleracea
''Roystonea oleracea'', sometimes known as the Caribbean royal palm, palmiste, imperial palm or cabbage palm, is a species of palm which is native to the Lesser Antilles, Colombia, Venezuela, and Trinidad and Tobago. It is also reportedly naturalized in Guyana and on the islands of Mauritius and Réunion in the Indian Ocean. Its specific epithet ''oleracea'' means "vegetable/herbal" in Latin and is a form of ().

Allée
In landscaping, an avenue (from the French), alameda (from the Portuguese and Spanish), or allée (from the French), is traditionally a straight path or road with a line of trees or large shrubs running along each side, which is used, as its Latin source ''venire'' ("to come") indicates, to emphasize the "coming to," or ''arrival'' at a landscape or architectural feature. In most cases, the trees planted in an avenue will be all of the same species or cultivar, so as to give uniform appearance along the full length of the avenue. The French term ''allée'' is used for avenues planted in parks and landscape gardens, as well as boulevards such as the ''Grande Allée'' in Quebec City, Canada, and ''Karl-Marx-Allee'' in Berlin. History The avenue is one of the oldest ideas in the history of gardens. An Avenue of Sphinxes still leads to the tomb of the pharaoh Hatshepsut. Avenues similarly defined by guardian stone lions lead to the Ming tombs in China. British archaeologists have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Transit Of Venus
frameless, upright=0.5 A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black dot moving across the face of the Sun. The duration of such transits is usually several hours (the transit of 2012 lasted 6 hours and 40 minutes). A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is more than three times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth. Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that generally repeats every 243 years, with pairs of transits eight years apart separated by long gaps of 121.5 years and 105.5 years. The periodicity is a reflection of the fact that the orbital periods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Bell (photographer)
William H. Bell (1830 – January 28, 1910) was an English-born American photographer, active primarily in the latter half of the 19th century. He is best remembered for his photographs documenting war-time diseases and combat injuries, many of which were published in the medical book, ''Medical and Surgical History of the War of the Rebellion'', as well as for his photographs of western landscapes taken as part of the Wheeler Survey, Wheeler expedition in 1872. In his later years, he wrote articles on the dry plate process and other techniques for various photography journals. Life Bell was born in Liverpool, Liverpool, England, in 1830, but immigrated to the United States with his parents as a young child. After his parents were killed in a cholera epidemic, he was raised by a Quaker family in Abington Township, Montgomery County, Pennsylvania, Abington, Pennsylvania, outside of Philadelphia. In 1846, at the outbreak of the Mexican–American War, Bell traveled to Louisiana a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria (plant)
''Victoria'' or giant waterlily is a genus of water-lilies, in the plant family Nymphaeaceae, with very large green leaves that lie flat on the water's surface. ''Victoria boliviana'' has a leaf that is up to in width, on a stalk up to in length. The genus name was given in honour of Queen Victoria of the United Kingdom. It pushes other water plants aside as it spreads out until only those of its kind remains. When this happens it has completely cut out the sunlight from getting to any plants below the water. All three species typically have four sepals each measuring long by wide. There are typically 50 to 70 petals and 150 to 200 stamens. Extant species The first published description of the genus was by John Lindley in 1837, based on specimens returned from British Guiana by Robert Schomburgk. Lindley named the genus after the new Queen, Victoria, and the species ''Victoria regia''. An earlier account of the species, ''Euryale amazonica'' Poeppig, in 1832 descr ...

Callithrix Jacchus
''Callithrix'' is a genus of New World monkeys of the family Callitrichidae, the family containing marmosets and tamarins. The genus contains the Atlantic Forest marmosets. The name ''Callithrix'' is derived from the Greek words ''kallos'', meaning beautiful, and ''thrix'', meaning hair. Taxonomy The genera ''Mico'' and ''Callibella'' were formerly considered a subgenus of the genus ''Callithrix''. ''Callithrix'' differs from ''Mico'' in dental morphology and geographic distribution; ''Callithrix'' species are distributed near the Atlantic coast of Brazil, while ''Mico'' species are distributed further inland. ''Callithrix'' differs from ''Callibella'' in these features, as well as in size, with ''Callithrix'' species being significantly larger. ''Callithrix'' species differ from the tamarins of the genus ''Saguinus'' in that ''Callithrix'' has enlarged mandibular incisor teeth the same size as the canine teeth, which are used for gouging holes in trees to extract exudates. ...

Sapajus Nigritus
The black capuchin (''Sapajus nigritus''), also known as the black-horned capuchin, is a capuchin monkey from the Atlantic Forest in south-eastern Brazil and far north-eastern Argentina. Historically, it was included as a subspecies of the tufted capuchin. Taxonomy The black capuchin was originally named ''Cebus nigritus'' or ''Cebus apella nigritus'', and while this has been changed, a lot of sources still name the black capuchin as part of the genus ''Cebus''. Social Behaviour Group Size The black capuchin is a social animal. It likes to live in groups, usually consisting of 6 to 20 members, and is hierarchal. Despite the fact that these groups tend to be made up of more females than males, the alpha female of the group is submissive to the alpha male. The size of the group operates as a function of food availability; size and cohesiveness are highest when food is readily available. When food is scarce, black capuchins split up into smaller groups to cover more ground o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
