Pierre-Paul Grassé
Pierre-Paul Grassé (November 27, 1895 in Périgueux (Dordogne) – July 9, 1985) was a French zoologist, writer of over 300 publications including the influential 52-volume ''Traité de Zoologie''. He was an expert on termites and one of the last proponents of neo-Lamarckian evolution. Biography Education Grassé began his studies in Périgueux where his parents owned a small business. He went on to study medicine at the University of Bordeaux and studied biology in parallel, including the lectures of the entomologist Jean de Feytaud (1881–1973). Mobilized during World War I, he was forced to interrupt his studies during four years. By the end of the war he was a military surgeon. Grassé continued his studies in Paris, focusing exclusively on science. He obtained his Licence in Biology and frequented the laboratory of biologist Étienne Rabaud (1868–1956). He abandoned his preparations for the agrégation to accept a position as professor in the École Nationale Supé ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Périgueux
Périgueux (, ; oc, Peireguers or ) is a communes of France, commune in the Dordogne departments of France, department, in the administrative regions of France, administrative region of Nouvelle-Aquitaine, southwestern France. Périgueux is the prefectures in France, prefecture of Dordogne, and the capital city of Périgord. It is also the seat of a Roman Catholic diocese. History The name ''Périgueux'' comes from Petrocorii, a Latinization of Celtic words meaning "the four tribes" – the Gaul, Gallic people that held the area before the Roman conquest. Périgueux was their capital city. In 200 BC, the Petrocorii came from the north and settled at Périgueux and established an encampment at La Boissière. After the Roman invasion, they left this post and established themselves on the plain of L'Isle, and the town of Vesunna was created. This Roman city was eventually embellished with amenities such as temples, baths, amphitheatres, and a forum. At the end of the third ce ...

Neo-Lamarckism
Lamarckism, also known as Lamarckian inheritance or neo-Lamarckism, is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime. It is also called the inheritance of acquired characteristics or more recently soft inheritance. The idea is named after the French zoologist Jean-Baptiste Lamarck (1744–1829), who incorporated the classical era theory of soft inheritance into his theory of evolution as a supplement to his concept of orthogenesis, a drive towards Evolution of biological complexity, complexity. Introductory textbooks contrast Lamarckism with Charles Darwin's theory of evolution by natural selection. However, Darwin's book ''On the Origin of Species'' gave credence to the idea of heritable effects of use and disuse, as Lamarck had done, and his own concept of pangenesis similarly implied soft inheritance. Many researchers from the 1860s onwards attempted to find evidence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Josias Braun-Blanquet
Josias Braun-Blanquet (3 August 1884 – 20 September 1980) was an influential phytosociologist and botanist. Braun-Blanquet was born in Chur, Switzerland and died in Montpellier, France. Biography Work In Josias Braun-Blanquet's dissertation, supervised by Charles Flahault, he worked on the phytosociology of the southern Cévennes. Subsequently he established the modern way of classifying vegetation according to floristic composition. This is what makes him one of the most influential botanists until today.Nicolson, M. (1993). National Styles, Divergent Classifications: A comparative case study from the history of French and American plant ecology. Knowledge and Society: Studies in the Sociology of Science Past and Present, 8, 139-186. Braun-Blanquet's way of classifying a plant community uses the scientific name of its most characteristic species as namesake, changing the ending of the generic name to "-etum" and treating the specific epithet as adjective.

Charles Flahault
Charles Henri Marie Flahault (3 October 1852 – 3 February 1935) was a French botanist, among the early pioneers of phytogeography, phytosociology, and forest ecology. The word '' relevé'' for a plant community sample is his invention. Early life and education Flahault was born in Bailleul, Nord, and received his Baccalauréat de Lettres at Douai in 1872, after which he became a gardener at the Jardin des Plantes de Paris. He was noticed by Joseph Decaisne (1807–1882), who gave him private lessons, after which he entered the Sorbonne in 1874 to study in the laboratory of Philippe Van Tieghem (1839–1914), obtaining his doctoral degree in biology in 1878. He continued his studies at Uppsala University in 1879 together with Gaston Bonnier. Career In 1881 joined the University of Montpellier where in 1883 he became professor of botany, and in 1890 he founded the ''Institut de Botanique''. The Swiss botanist Josias Braun-Blanquet was one of his students In 1888 Flahault was ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytogeography
Phytogeography (from Greek φυτόν, ''phytón'' = "plant" and γεωγραφία, ''geographía'' = "geography" meaning also distribution) or botanical geography is the branch of biogeography that is concerned with the geographic distribution of plant species and their influence on the earth's surface. Phytogeography is concerned with all aspects of plant distribution, from the controls on the distribution of individual species ranges (at both large and small scales, see species distribution) to the factors that govern the composition of entire communities and floras. Geobotany, by contrast, focuses on the geographic space's influence on plants. Fields Phytogeography is part of a more general science known as biogeography. Phytogeographers are concerned with patterns and process in plant distribution. Most of the major questions and kinds of approaches taken to answer such questions are held in common between phyto- and zoogeographers. Phytogeography in wider sense (or geobot ...

Agrégation
In France, the ''agrégation'' () is a competitive examination for civil service in the French public education system. Candidates for the examination, or ''agrégatifs'', become ''agrégés'' once they are admitted to the position of ''professeur agrégé''. In France, ''professeurs agrégés'' are distinguished from ''professeurs certifiés'' recruited through the CAPES training. The ''agrégés'' are usually expected to teach in sixth-form colleges (''lycées'') and universities, while the ''certifiés'' usually teach in secondary schools (''collèges''), although there is a significant overlap. The examination may require more than a year of preparation. The difficulty and selectivity (quota) vary from one discipline to another: there are about 300 such positions open each year for mathematics alone, but usually fewer positions are made available for humanities and social sciences (for example, 61 positions for philosophy were offered in 2018) and perhaps only one seat in som ...

Licence
A license (or licence) is an official permission or permit to do, use, or own something (as well as the document of that permission or permit). A license is granted by a party (licensor) to another party (licensee) as an element of an agreement between those parties. In the case of a license issued by a government, the license is obtained by applying for it. In the case of a private party, it is by a specific agreement, usually in writing (such as a lease or other contract). The simplest definition is "A license is a promise not to sue," because a license usually either permits the licensed party to engage in an activity which is illegal, and subject to prosecution, without the license (e.g. fishing, driving an automobile, or operating a broadcast radio or television station), or it permits the licensed party to do something that would violate the rights of the licensing party (e.g. make copies of a copyrighted work), which, without the license, the licensed party could be ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
