Baudin Expedition To Australia
The Baudin expedition of 1800 to 1803 was a French expedition to map the coast of New Holland (now Australia). Nicolas Baudin was selected as leader in October 1800. The expedition started with two ships, '' Géographe'', captained by Baudin, and ''Naturaliste'' captained by Jacques Hamelin, and was accompanied by nine zoologists and botanists, including Jean-Baptiste Leschenault de la Tour, François Péron and Charles-Alexandre Lesueur as well as the geographer Pierre Faure. Expedition Napoléon Bonaparte, as First Consul, formally approved the expedition "to the coasts of New Holland", after receiving a delegation consisting of Baudin and eminent members of thInstitut National des Sciences et Artson 25 March 1800. The explicit purpose of the voyage was to be "observation and research relating to Geography and Natural History." The Baudin expedition departed Le Havre, France, on 19 October 1800. Because of delays in receiving his instructions and problems encountered in Is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
European And American Voyages Of Scientific Exploration
The era of European and American voyages of scientific exploration followed the Age of Discovery and were inspired by a new confidence in science and reason that arose in the Age of Enlightenment. Maritime expeditions in the Age of Discovery were a means of expanding colonial empires, establishing new trade routes and extending diplomatic and trade relations to new territories, but with the Enlightenment scientific curiosity became a new motive for exploration to add to the commercial and political ambitions of the past. See also List of Arctic expeditions and List of Antarctic expeditions. Maritime exploration in the Age of Discovery From the early 15th century to the early 17th century the Age of Discovery had, through Spanish and Portuguese seafarers, opened up southern Africa, the Americas (New World), Asia and Oceania to European eyes: Bartholomew Dias had sailed around the Cape of southern Africa in search of a trade route to India; Christopher Columbus, on four journeys ...

Scurvy
Scurvy is a disease resulting from a lack of vitamin C (ascorbic acid). Early symptoms of deficiency include weakness, feeling tired and sore arms and legs. Without treatment, decreased red blood cells, gum disease, changes to hair, and bleeding from the skin may occur. As scurvy worsens there can be poor wound healing, personality changes, and finally death from infection or bleeding. It takes at least a month of little to no vitamin C in the diet before symptoms occur. In modern times, scurvy occurs most commonly in people with mental disorders, unusual eating habits, alcoholism, and older people who live alone. Other risk factors include intestinal malabsorption and dialysis. While many animals produce their own vitamin C, humans and a few others do not. Vitamin C is required to make the building blocks for collagen. Diagnosis is typically based on physical signs, X-rays, and improvement after treatment. Treatment is with vitamin C supplements taken by mouth. Improvemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louis François Auguste Souleyet
Louis François Auguste Souleyet (8 January 1811 – 7 October 1852) was a French zoologist, malacologist and naval surgeon. Souleyet was naturalist-surgeon on the voyage of ''La Bonite'', which circumnavigated the globe between February 1836 and November 1837 under Auguste Nicolas Vaillant (1793–1858). In the Pacific he studied marine molluscs. After the death of Joseph Fortuné Théodore Eydoux (1802–1841), Souleyet completed the zoological section of the voyage's official report in 1852. Souleyet died of yellow fever in Martinique in 1852. He named a number of marine molluscs and fish, but most of his new taxa were validated two years earlier by John Edward Gray, who Latinized all vernacular names published earlier in an undated (1842 ?) atlas by Eydoux & Souleyet. He is himself commemorated in the scientific name of the streak-headed woodcreeper, ''Lepidocolaptes souleyetii'', named for him by DesMurs and in the Heteropod '' Protatlanta souleyeti'' by Edgar A. Smith in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxygyrus Keraudrenii
''Oxygyrus keraudrenii'' is a species of sea snail, a holoplanktonic marine gastropod mollusk in the family Atlantidae. ''Oxygyrus keraudrenii'' is the only species in the genus ''Oxygyrus''. Description ''Oxygyrus keraudreni'' (along with '' Atlanta peronii'') attains the largest size (shell diameter to 10 mm) among the Atlantidae.Welch J. J. (2010). "The "Island Rule" and Deep-Sea Gastropods: Re-Examining the Evidence". '' PLoS ONE'' 5(1): e8776. . Body coloration is light bluish-purple, with the color darkening with age. The larval shell is calcareous and displays a distinctive pattern of zigzag-shaped spiral ridges that are evenly spaced and cover the shell surface. The teleoconch is composed of conchiolin, a transparent cartilaginous material, and its surface lacks sculpture. With growth the teleoconch overgrows the protoconch and eventually surrounds it. A shell spire, as seen in all other atlantids, is lacking and the spire region is termed involute. The conchiolin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species. The anatomy, behavior, feeding, and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prosper Garnot
Prosper Garnot (13 January 1794 – 8 October 1838) was a French surgeon and naturalist. Garnot was born at Brest. He was an assistant surgeon under Louis Isidore Duperrey on ''La Coquille'' during its circumnavigation of the globe (1822–1825). Along with René Primevère Lesson he collected numerous natural history specimens in South America and the Pacific. Garnot had a severe attack of dysentery and was sent back with some of the collection on the ''Castle Forbes''. The specimens were lost when the ship was wrecked off the Cape of Good Hope in July 1824. With Lesson he wrote the zoological section of the voyage's report, ''Voyage autour du monde exécuté par order du roi sur la corvette La Coquille'' (1828–1832). He died, aged 44, in Paris.
