Arbutus Canariensis
''Arbutus canariensis'', known in Spanish as ''madroño canario'', is a species of shrub or tree in the Ericaceae, heath family. It is Endemism, endemic to the Canary Islands of Spain, specifically Tenerife, La Gomera, Gran Canaria, El Hierro, and La Palma. It is threatened by habitat loss. Hybrids ''Arbutus'' x ''thuretiana'' Demoly is a hybrid between ''A. canariensis'' and ''Arbutus andrachne, A. andrachne''. Named after Gustave Thuret, it is naturalised at Jardin botanique de la Villa Thuret. ''A.'' x ''thuretiana'' is renowned for its perfectly smooth, reddish-brown bark, exfoliating in the spring to show a new, surprisingly pistachio-green bark, which gradually darkens and turns reddish again.

Henri-Louis Duhamel Du Monceau
Henri-Louis Duhamel du Monceau (20 July 1700, Paris13 August 1782, Paris), was a French physician, naval engineer and botanist. Biography Henri-Louis Duhamel du Monceau was born in Paris in 1700, the son of Alexandre Duhamel, lord of Denainvilliers. In his youth he developed a passion for botany, but at his father's wish he studied law from 1718 to 1721. After inheriting his father's large estate, he expanded it into a model farm, where he developed and tested new methods of horticulture, agriculture and forestry. The results of this work, he published in numerous publications. Commission by the French Academy of Sciences in 1728 Duhamel investigate the saffron cultivation in Gâtinais. In the following years continued to investigate physiological problems of crops. He also investigated growth of the trees in cooperation with Georges-Louis Leclerc de Buffon. From 1740 he also started focusing on meteorological problems, in particular their impact on agricultural production. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trees Of Mediterranean Climate
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemic Flora Of The Canary Islands
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Jardin Botanique De La Villa Thuret
The Jardin botanique de la Villa Thuret () is a renowned botanical garden located on the grounds of the Villa Thuret, 90, chemin Raymond, Antibes Juan-les-Pins, Alpes-Maritimes, Provence-Alpes-Côte d'Azur, France. It is open weekdays without charge. Overview The garden was created in 1857 by Gustave Thuret (1817-1875), a botanist best known for studies of reproduction in algae, who used it to conduct plant acclimatization trials with friend and lichen expert Jean-Baptiste Édouard Bornet (1828-1911). In 1868, novelist George Sand described it in her ''Traveller's Letters'' as the loveliest garden she had ever seen. It was bequeathed to the nation in 1878, and in 1927 attached to the Institute of Agronomic Research, which in 1946 became the Institut National de la Recherche Agronomique (INRA). Today the garden contains approximately 2,500 trees and shrubs in its collections, representing some 1,600 exotic species (144 genera, 131 families) from Mediterranean or hot climate co ...

Gustave Thuret
Gustave Adolphe Thuret (23 May 1817 – 10 May 1875) was a noted French botanist, and founder of the Jardin botanique de la Villa Thuret. Biography Born in Paris, he belonged to an old Huguenot family, which had sought refuge in Weesp (Dutch Republic) after the revocation of the Edict of Nantes. In 1808 his father, a merchant and banker, married in London Henrietta van der Paadevoort (Padevoirt), the daughter of a navy officer, born in Demerara (now Guyana), but brought up or educated in England. In 1811 the family moved from Bath to Paris, where Isaac Thuret was appointed as the Dutch consul. As a young man Gustave studied Law, while being an amateur musician, and it was from a musical friend, de Villers, that he received, in 1837, his first initiation into botany. Beginning simply as a collector, he soon came under the influence of Joseph Decaisne, whose pupil he became. It was Decaisne who first encouraged him to undertake those algological studies which were to become the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Ericaceae
The Ericaceae are a family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with c.4250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (''Erica'', ''Cassiope'', ''Daboecia'', and ''Calluna'' for example). Description The Ericaceae contain a morphologically diverse range of taxa, including herbs, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are hermaphrodite and show considerable variability. The petals are often fused (sympetalous) with shapes ranging from narrowly tubular to funnelform or widely urn-shaped. The corollas are usually ra ...

La Palma
La Palma (, ), also known as ''La isla bonita'' () and officially San Miguel de La Palma, is the most north-westerly island of the Canary Islands, Spain. La Palma has an area of making it the fifth largest of the eight main Canary Islands. The total population at the end of 2020 was 85,840, of which 15,716 lived in the capital, Santa Cruz de La Palma and about 20,467 in Los Llanos de Aridane. Its highest mountain is the Roque de los Muchachos, at , being second among the peaks of the Canaries only to the peaks of the Teide massif on Tenerife. In 1815, the German geologist Leopold von Buch visited the Canary Islands. It was as a result of his visit to Tenerife, where he visited the Las Cañadas caldera, and then later to La Palma, where he visited the Taburiente caldera, that the Spanish word for cauldron or large cooking pot – "caldera" – was introduced into the geological vocabulary. In the center of the island is the Caldera de Taburiente National Park; one of four nation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
