Trilepisium Gymnandrum
''Trilepisium gymnandrum'' is a species of ''Trilepisium'' that is endemic to the Seychelles, where it is threatened by habitat loss. Its natural habitat is subtropical or tropical moist lowland forests. Five mature individuals are known in two sub-populations in the mid to high altitude forests of Silhouette Island. The 18th century populations of the larger Mahé and Praslin islands have presumably been extirpated. The NPTS has established a new population on Silhouette island.

John Gilbert Baker
John Gilbert Baker (13 January 1834 – 16 August 1920) was an English botanist. His son was the botanist Edmund Gilbert Baker (1864–1949). Biography Baker was born in Guisborough in North Yorkshire, the son of John and Mary (née Gilbert) Baker, and died in Kew. He was educated at Quaker schools at Ackworth School and Bootham School, York. He then worked at the library and herbarium of the Royal Botanic Gardens, Kew between 1866 and 1899, and was keeper of the herbarium from 1890 to 1899. He wrote handbooks on many plant groups, including Amaryllidaceae, Bromeliaceae, Iridaceae, Liliaceae, and ferns. His published works includ''Flora of Mauritius and the Seychelles''(1877) and ''Handbook of the Irideae'' (1892). He married Hannah Unthank in 1860. Their son Edmund was one of twins, and his twin brother died before 1887. John G. Baker was elected a Fellow of the Royal Society in 1878.

Trilepisium
''Trilepisium'', the urnfigs or false-figs, is a small Afrotropical genus of plants in family Moraceae. They grow to medium-sized or large trees that occur in evergreen and semi-deciduous forests, flooded forests or forest patches and often along rivers and streams, and at elevations of up to 2,000 m and over. Description The bole may be 60 cm wide, and is often fluted at the base. The smooth, grey bark is very lenticellate and exudes a cream-coloured latex when damaged. The yellowish to pinkish slash turns purple-red as it dries. They usually branch high up to form a small and loosely pyramidal crown with drooping twigs. Stipules of terminal buds eventually leave annular scars. The glossy and very dark elliptic leaves have a prominent driptip, and measure up to 14 cm long. They are glossy below, and have two small lobes at the base. The flowers appear in spring and are arranged in a whitish to mauve puff. The puff is about 1 cm in diameter, and consists of stam ...

Endemic
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] |
Seychelles
Seychelles (, ; ), officially the Republic of Seychelles (french: link=no, République des Seychelles; Creole: ''La Repiblik Sesel''), is an archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is east of mainland Africa. Nearby island countries and territories include the Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and Maldives and the Chagos Archipelago (administered by the United Kingdom as the British Indian Ocean Territory) to the east. It is the least populated sovereign African country, with an estimated 2020 population of 98,462. Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until coming under full British control in the late 18th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural society to ... [...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 ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Silhouette Island
Silhouette Island lies northwest of Mahé in the Seychelles. It is the third largest granitic island in the Seychelles. It has an area of 20.1 km2 and has a population of 200, mostly workers on the island. The main settlement is La Passe, where ''Hilton Hotel'' is located. The name Silhouette was given after Étienne de Silhouette (1709-1767), the French minister of finances under Louis XV. Geography The island is mountainous with five peaks over in elevation; Mont Dauban , Mont-Pot-a-Eau , Gratte Fesse , Mont Corgat and Mont Cocos Marrons . As such, it has some of the most dramatic scenery of the islands. Though superficially similar to neighbouring islands, much of Silhouette is made up of younger syenite dated from 63 million years ago. Between Point Ramasse Tout and Point Zeng Zeng lies the only surface volcanic ash in Seychelles. Demographics The population of 200 lives in 3 villages, Grand Barbe (no longer inhabited), which is on the west coast, Anse Mondon (no ...

Mahé, Seychelles
Mahé is the largest island of Seychelles, with an area of , lying in the northeast of the Seychellean nation in the Somali Sea part of the Indian Ocean. The population of Mahé was 77,000, as of the 2010 census. It contains the capital city of Victoria and accommodates 86% of the country's total population. The island was named after Bertrand-François Mahé de La Bourdonnais, a French governor of Isle de France (modern-day Mauritius). History Mahé was first visited by the British in 1609 and not visited by Europeans again until Lazare Picault's expedition of 1742. The French navy frégate '' Le Cerf'' (English: The Deer) arrived at Port Victoria on 1 November 1756. On board was Corneille Nicholas Morphey, leader of the French expedition, which claimed the island for the King of France by laying a Stone of Possession on Mahé, Seychelles’ oldest monument, now on display in the National Museum, Victoria. In August 1801 a Royal Navy frigate HMS ''Sibylle'' captured t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Praslin
Praslin () is the second largest island (38.5 km2) of the Inner Seychelles, lying northeast of Mahé in the Somali Sea. Praslin has a population of around 7,533 people and comprises two administrative districts: Baie Sainte Anne and Grand' Anse. The main settlements are the Baie Ste Anne, Anse Volbert and Grand' Anse. It was named ''Isle de Palmes'' by explorer Lazare Picault in 1744. During that time it was used as a hideaway by pirates and Arab merchants. In 1768 it was renamed ''Praslin'' in honor of French diplomat César Gabriel de Choiseul, duc de Praslin. Praslin is known as a tourist destination with several hotels and resorts, as well as a number of beaches such as Anse Lazio and Anse Georgette. It has substantial tracts of tropical forests with birds such as the endemic Seychelles bulbul and the Seychelles black parrot.
