Pierre Chouard
Pierre Chouard (Paris, 29 October 1903 - Paris, 11 December 1983) was a French botanist, specialising in plant physiology. Biography He entered the École normale supérieure, in the class of 1924, and graduated in natural sciences in 1927. In 1930, he participated in the formation of the International Mediterranean and Alpine Geobotany Station in Montpellier. He was professor of plant physiology at the Sorbonne and director of the plant research establishment Phytotron at Gif-sur-Yvette. In 1962, with his friend Henri Gaussen, he was instrumental in the creation of the Pyrenees National Park.Sophie Bobbé, ''Il était une fois un parc... : Histoire de la création du parc national des Pyrénées'', dans ''Histoire des parcs nationaux'', Éditions Quae, 2009 Both went on to be part of the park's Scientific Committee. He was a member of the Académie d'agriculture de France, a founding member of the Société française de physiologie végétale, and President of the Société ...

Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Collège Des Écossais, Montpellier
The College Des Ecossais (Scots College) was founded by Patrick Geddes in 1924 as an international teaching establishment located in Montpellier, in the south of France. The site When coming back in Europe in 1924 after a long stay in India, Geddes decided to settle with his daughter Norah in Montpellier, a city that was already linked with Scotland since the Middle Ages, when it became the European capital of medicine: "In this he was harking back to medieval ideas, looking for unity among scholars who saw a wholeness in their studies and in where they lived with others from other lands". As the Jardin des plantes de Montpellier, first botanical garden in France, was implemented there in 1593 as part of the medicine faculty, the place had a long-standing tradition in these sciences. Moreover, the biologist Charles Flahault, that Geddes considered the greatest of their times was living there. « The concept of the Scots College as an international students’ Center emerged during G ...

Phytotron
A phytotron is an enclosed research greenhouse used for studying interactions between plants and the environment. It was a product of the disciplines of plant physiology and botany. Overview Phytotrons unified and extended earlier piecemeal efforts to claim total control of the whole environment. In both walk-in rooms and smaller reach-in cabinets, phytotrons produced and reproduced whole complex climates of many variables. In the first phytotrons each individual room was held at a constant unique temperature. The Australian phytotron, for example, had rooms maintaining 9°C, 12°C, 16°C, 20°C, 23°C, 26°C, 30°C, 34°C. Because some of the earliest controlled environment experiments showed that plants reacted differently in daytime temperatures and nighttime temperatures, the first experiments to observe the effect(s) of varying the daytime versus the nighttime temperature saw experimenters move their plants from higher to lower temperatures over the course of a daily, or any o ...

Henri Gaussen
Marcel-Henri Gaussen (14 July 1891 in Cabrières-d'Aigues (Vaucluse) - 27 July 1981 in Toulouse), was a French botanist and biogeographer. In 1926, he defended his thesis on "the vegetation of the eastern half of the Pyrenees", which laid the foundation for future work on the border between biogeography and vegetation mapping. Gaussen was an early advocate of the ideas of stages and vegetation succession, which are fundamental to phytogeography. His work allowed for the production of a vegetation map of France at a scale of 1/200 000 (completed after his death by the service of the CNRS, but which he had created and directed) and many similar projects in other countries. His work led to many advanced phytogeographic tools such as the xerothermic or Gaussen Index, and the "". As recognition for his scientific work in mapping of vegetation cover and ecology, he received the Grand Prix of the Geographical Society for geographical research and publications in 1971. He was also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pyrenees National Park
The Pyrenees (; es, Pirineos ; french: Pyrénées ; ca, Pirineu ; eu, Pirinioak ; oc, Pirenèus ; an, Pirineus) is a mountain range straddling the border of France and Spain. It extends nearly from its union with the Cantabrian Mountains to Cap de Creus on the Mediterranean coast. It reaches a maximum altitude of at the peak of Aneto. For the most part, the main crest forms a divide between Spain and France, with the microstate of Andorra sandwiched in between. Historically, the Crown of Aragon and the Kingdom of Navarre extended on both sides of the mountain range. Etymology In Greek mythology, Pyrene is a princess who gave her name to the Pyrenees. The Greek historian Herodotus says Pyrene is the name of a town in Celtic Europe. According to Silius Italicus, she was the virgin daughter of Bebryx, a king in Mediterranean Gaul by whom the hero Hercules was given hospitality during his quest to steal the cattle of Geryon during his famous Labours.

Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brimeura Amethystina
''Brimeura amethystina'', the amethyst hyacinth, is a flowering plant of the asparagus family Asparagaceae, native to the Northern Pyrenees and north east Spain. The record from the Kapela mountain (Croatia) by Reichenbach (1830) is probably a confusion with some ''Hyacinthella'' taxon growing in the Balkan area.Rubim M.

Taxonomy of the genus Brimeura (Hyacinthaceae) – Folia Geobotanica 36: 193-208, 2001 The amethyst hyacinth, a small bulbous herbaceous perennial to , it has narrow grass-like leaves, and widely-spaced bell flowers in shades of pale blue, dark blue or violet in Spring. There is also a white cultivar ‘Alba’. It was formerly placed in the hyacinth genus ''Hyacinthus''. The Latin specific epithet ''amethystina'' means “violet coloured”.
