The Gentleman's Magazine
''The Gentleman's Magazine'' was a monthly magazine founded in London, England, by Edward Cave in January 1731. It ran uninterrupted for almost 200 years, until 1922. It was the first to use the term ''magazine'' (from the French ''magazine'', meaning "storehouse") for a periodical. Samuel Johnson's first regular employment as a writer was with ''The Gentleman's Magazine''. History The original complete title was ''The Gentleman's Magazine: or, Trader's monthly intelligencer''. Cave's innovation was to create a monthly digest of news and commentary on any topic the educated public might be interested in, from commodity prices to Latin poetry. It carried original content from a stable of regular contributors, as well as extensive quotations and extracts from other periodicals and books. Cave, who edited ''The Gentleman's Magazine'' under the pen name "Sylvanus Urban", was the first to use the term ''magazine'' (meaning "storehouse") for a periodical. Contributions to the magazi ...

Type (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost al ...

Pousargues's Mongoose
Pousargues's mongoose (''Dologale dybowskii''), also known as the African tropical savannah mongoose, is a mongoose native to Central Africa. It is listed as data deficient on the IUCN Red List as little is known about its distribution and ecology. It is the only species in the genus ''Dologale''. Up to the late 20th century, it was known from only around 30 zoological specimens in natural history museum collections. Characteristics The Pousargues's mongoose is brown with a grey belly and face. Its tail is bushy, and its front feet have strong claws. Its body length is between with a long tail. Taxonomy In 1893, Eugène de Pousargues first described the Pousargues's mongoose on the basis of zoological specimens collected in 1892 near the Kémo River. The type locality corresponds to the former French garrison founded by the Dybowski Mission close to the settlement of Fort de Possel. It is named in honor of Jean Dybowski who collected the specimens. It was initially subor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zoology
Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the Animal, animal kingdom, including the anatomy, structure, embryology, evolution, Biological classification, classification, Ethology, habits, and distribution of all animals, both living and extinction, extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and made use of this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dybowski's Twinspot
Dybowski's twinspot (''Euschistospiza dybowskii'') is a common species of estrildid finch found in Africa. It has an estimated global extent of occurrence of 450,000 km2. It is found in Cameroon, Central African Republic, Chad, The Democratic Republic of the Congo, Côte d'Ivoire, Guinea, Liberia, Nigeria, Senegal, Sierra Leone, South Sudan and Uganda. The status of the species is evaluated as Least Concern. The name of this bird commemorates the French botanist Jean Dybowski.

Émile Oustalet
Jean-Frédéric Émile Oustalet (24 August 1844 – 23 October 1905 Saint-Cast) was a French zoologist.Hellmayr CE (1906). "Emile Oustalet bituary. ''Ornithologische Monatsberichte'' 14 (4): 57-59Scan Oustalet was born at Montbéliard, in the department of Doubs. He studied at the Ecole des Hautes-Etudes and his first scientific work was on the respiratory organs of dragonfly larvae. He was employed at the Muséum National d'Histoire Naturelle, where he succeeded Jules Verreaux as assistant-naturalist in 1873. In 1900 he succeeded Alphonse Milne-Edwards as Professor of Mammalogy. French ornithologist Émile Oustalet described a specimen from Branco as a separate species ''Passer brancoensis'' in 1883, which was recognised as the subspecies ''Passer iagoensis brancoensis'' by W. R. P. Bourne, who claimed to observe differences between Iago sparrows from different islands. He co-authored ''Les Oiseaux de la Chine'' (1877) with Armand David, and also wrote ''Les Oiseaux du Cambodg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornithologist
Ornithology is a branch of zoology that concerns the "methodological study and consequent knowledge of birds with all that relates to them." Several aspects of ornithology differ from related disciplines, due partly to the high visibility and the aesthetic appeal of birds. It has also been an area with a large contribution made by amateurs in terms of time, resources, and financial support. Studies on birds have helped develop key concepts in biology including evolution, behaviour and ecology such as the definition of species, the process of speciation, instinct, learning, ecological niches, guilds, island biogeography, phylogeography, and conservation. While early ornithology was principally concerned with descriptions and distributions of species, ornithologists today seek answers to very specific questions, often using birds as models to test hypotheses or predictions based on theories. Most modern biological theories apply across life forms, and the number of scientists who i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
