The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Araneomorphae
The Araneomorphae (also called the Labidognatha) are an infraorder of spiders. They are distinguishable by chelicerae (fangs) that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae (tarantulas and their close kin), where they point straight down. Araneomorphs comprise the vast majority of living spiders. Distinguishing characteristics Most spider species are Araneomorphae, which have fangs that face towards each other, increasing the orientations they can employ during prey capture. They have fewer book lungs (when present), and the females typically live one year. The Mygalomorphae have fangs that face towards the ground, and which are parallel to the long axis of the spider's body, thus they have only one orientation they can employ during prey capture. They have four pairs of book lungs, and the females often live many years. Image:Atrax robustus.jpg, This ''Atrax robustus'' shows the orientation of Myglamorphae fangs. Image:Che ...

Endemism
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] |
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 ...

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. The Vallée de Mai Nature Preserve, established in 1979, is known for the unique coco de mer and vanilla orchids. It has been reported ...

Curieuse Island
Curieuse Island is a small granitic island in the Seychelles close to the north coast of the island of Praslin. Curieuse is notable for its bare red earth intermingled with the unique coco de mer palms, one of the cultural icons of the Seychelles, only growing on the two neighboring islands. History Originally named "Ile Rouge" due to its red coloured soil. In 1768 the French claimed possession of the island, naming it after the schooner "La Curieuse", a ship that was under the command of explorer Marc-Joseph Marion du Fresne. Like a number of islands in the Seychelles, there was a native giant tortoise population that was quickly extirpated. In 1829, Curieuse was first used as a leper colony, and it functioned in this capacity until 1965. This helped protect the ecosystem from human influence. Today, ruins of the leprosarium remain, as well as the former physician's residence at Anse St. Joseph (now an educational center and museum). Conservation In 1967 a fire destroyed mu ...

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] |
Cinnamomum Verum
''Cinnamomum verum'', called true cinnamon tree or Ceylon cinnamon tree, is a small evergreen tree belonging to the family Lauraceae, native to Sri Lanka. The inner bark of several other ''Cinnamomum'' species are also used to make cinnamon, but ''C. verum'' has a more subtle flavor. Description ''Cinnamomum verum'' trees are 10–15 metres (30–50 feet) tall. The leaves are ovate-oblong in shape and 7–18 cm (3–7 inches) long. The flowers, which are arranged in panicles, have a greenish color and a distinct odour. The fruit is a purple 1cm drupe containing a single seed. Cultivation The old botanical synonym for the tree, ''Cinnamomum zeylanicum'', is derived from Sri Lanka's former name, Ceylon. Sri Lanka still produces 80–90% of the world's supply of ''C. verum'', which is also cultivated on a commercial scale in the Seychelles, Madagascar and Tanzania. Cultivars There are several different cultivars of ''Cinnamomum verum'' based on the taste of bark: * Type 1 – si, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endangered Animals
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiders Described In 1996
Spiders (order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate th ...
