Dallas World Aquarium
The Dallas World Aquarium is a for-profit aquarium and zoo located in the West End Historic District of Dallas, Texas, USA. It aids conservation and education by housing many animals that are threatened or endangered as part of a cooperative breeding program with other zoos around the world. It has been an accredited member of the Association of Zoos and Aquariums since 1997 and is a member of the World Association of Zoos and Aquariums. History The aquarium was opened in October 1992 in an old 1924 warehouse that had been gutted and rebuilt on the inside. In 1997, "The Orinoco - Secrets of the River" opened in an adjacent warehouse that had been similarly gutted and transformed, and the alley between the two buildings became the divide between freshwater and saltwater exhibits. In May 2000, it purchased a vacant lot behind the original warehouse for its first new construction, the Mundo Maya exhibit, which opened in August 2004. In 2015 Ben Crair of the New Republic wrote an ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coevolution
In biology, coevolution occurs when two or more species reciprocally affect each other's evolution through the process of natural selection. The term sometimes is used for two traits in the same species affecting each other's evolution, as well as gene-culture coevolution. Charles Darwin mentioned evolutionary interactions between flowering plants and insects in ''On the Origin of Species'' (1859). Although he did not use the word coevolution, he suggested how plants and insects could evolve through reciprocal evolutionary changes. Naturalists in the late 1800s studied other examples of how interactions among species could result in reciprocal evolutionary change. Beginning in the 1940s, plant pathologists developed breeding programs that were examples of human-induced coevolution. Development of new crop plant varieties that were resistant to some diseases favored rapid evolution in pathogen populations to overcome those plant defenses. That, in turn, required the development of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1758
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. Birds ...

Selenidera
''Selenidera'' is a bird genus containing six species of dichromatic toucanets in the toucan family Ramphastidae. They are found in lowland rainforest (below ) in tropical South America with one species in Central America. All the species have green upper-parts, red undertail-coverts and a patch of bare blue or blue-green skin around the eye. Unlike most other toucans, the sexes are different in colour (sexually dichromatic; hence the name dichromatic toucanets). The males all have a black crown, nape, throat and breast and an orange/yellow auricular streak. The females of most species have the black sections in the male replaced by rich brown and a reduced/absent auricular streak, while the female of one species, the Guianan toucanet, has grey underparts and a rufous nuchal collar, and the female of another, the yellow-eared toucanet, resemble the male except for its brown crown and lack of an auricular streak. The calls are low-pitched and croaking. Most species are relatively s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Henry Constantine Richter
Henry Constantine Richter (7 June 1821 – 16 March 1902) was an English zoological illustrator who produced a very large number of skillful coloured lithographs of birds and mammals, mainly for the scientific books of the renowned English 19th century ornithologist John Gould. Many of the original drawings used by Richter as the basis for his coloured lithographs were by Gould's wife, Elizabeth Coxen, produced before her death in 1841.Stephens, M 2009, ''Henry Constantine Richter (about 1821-1902)'', Australian Museum, Sydney NSW, accessed 02 Dec 2017, https://australianmuseum.net.au/henry-constantine-richter-about-1821-1902.Cook, KS 2013, ‘Gould collections at KU: the story of the Gould Collection’, ''John Gould: Bird Illustration in the Age of Darwin'', University of Kansas, accessed 3 Dec 2017, https://exhibits.lib.ku.edu/exhibits/show/gould/about/kucollections.

Biography Sturm was born in Nuremberg, Nürnberg, the eldest son of copperplate engraver Jacob Sturm and his wife Christine Albertine Wilhelmine née Wagner. He studied from 1820 to 1828 at the Nürnberg art school specializing in portraiture.

Elizabeth Gould (illustrator)
Elizabeth Gould, née Coxen (1804—1841), was a British artist and illustrator at the forefront of the natural history movement. Elizabeth traveled and worked alongside her husband, naturalist and author John Gould. She produced illustrations and lithographs for ornithological works, including plates in Darwin's '' The Zoology of the Voyage of H.M.S. Beagle'' and the Goulds' seminal work '' The Birds of Australia''. In total, Elizabeth is accredited to at least 650 works. Life and artistic career Elizabeth was born on 18 July 1804 in Ramsgate, England to a military family. Little is known of her early life, however it is likely that Elizabeth Elizabeth likely underwent training in drawing and botany from a young age. In Victorian England, botany and natural history were part of the education of girls in middle-class English families. As Ann Moyal stated, “Cultivated women drew, walked, observed, collected specimens, arranged and painted." After this, at twenty-two, Elizabe ...

John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained a position on an estate near Guildford, Surrey, and then in 1818, Gould Snr became foreman in the Royal Gardens of Windsor.
