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] |
La Digue
La Digue is the third most populated island of the Seychelles, and fourth largest by land area, lying east of Praslin and west of Felicite Island. In size, it is the fourth-largest granitic island of Seychelles after Mahé, Praslin and Silhouette Island. It has a population of 2,800 people. Most of the inhabitants live in the west coast villages of La Passe (linked by ferry to Praslin and Mahé) and Anse Réunion. There is no airport on La Digue, so to get there from a foreign country, one must fly to Victoria and continue by ferry, usually via Praslin. It has an area of 10.08 km2, which makes it relatively easy to travel around by bike or on foot. La Digue was named after a ship in the fleet of French explorer Marc-Joseph Marion du Fresne, who visited the Seychelles in 1768. History According to modern historians, La Digue was first sighted by the French navigator Lazare Picault in 1742, but it was not named until 1768. The first people settled on the island in 1789, whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiders Of Africa
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 t ...

Endemic Fauna Of Seychelles
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 s ... [...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] |
Nephila Inaurata
''Trichonephila inaurata'', synonym ''Nephila inaurata'', commonly known as the red-legged golden orb-weaver spider or red-legged nephila, is a species of orb-weaver spider of the genus '' Trichonephila''. It is native to southern and East Africa, as well as several islands of the western Indian Ocean (Madagascar, the Seychelles, Réunion, Mauritius, Rodrigues). Web spinning and structure ''Trichonephila'' spiders produce large asymmetric orb webs up to in diameter. ''Trichonephila'' species remain in their webs permanently, so have a higher predation risk. The golden silk orb-weaver is named for the yellow color of the spider silk used to construct these webs. Yellow threads of their web shine like gold in sunlight. Carotenoids are the main contributors to this yellow color, but xanthurenic acid, two quinones, and an unknown compound may also aid in the color. Experimental evidence suggests that the silk's color may serve a dual purpose: sunlit webs ensnare bees that are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kleptoparasitism
Kleptoparasitism (etymologically, parasitism by theft) is a form of feeding in which one animal deliberately takes food from another. The strategy is evolutionarily stable when stealing is less costly than direct feeding, which can mean when food is scarce or when victims are abundant. Many kleptoparasites are arthropods, especially bees and wasps, but including some true flies, dung beetles, bugs, and spiders. Cuckoo bees are specialized kleptoparasites which lay their eggs either on the pollen masses made by other bees, or on the insect hosts of parasitoid wasps. They are an instance of Emery's rule, which states that insect social parasites tend to be closely related to their hosts. The behavior occurs, too, in vertebrates including birds such as skuas, which persistently chase other seabirds until they disgorge their food, and carnivorous mammals such as spotted hyenas and lions. Other species opportunistically indulge in kleptoparasitism. Strategy Kleptoparasitism is a fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Marianne Island
Marianne Island is a small Granitic Seychelles, granitic island of the Seychelles. in size, it is located 3.8 km ESE of Félicité Island. The island was a former coconut plantation, and on the western side of the island is a long beach. The southern tip of Marianne is known as a world-class diving location. The tallest peak on the island is Estel Hill, at 130 meters. Presently, Marianne Island is uninhabited but is routinely visited by tourists and boaters. For much of the 19th and 20th century, farming and copra production took place on Marianne. There was a former settlement called La Cour, and in 1940 the island had 60 inhabitants. There are a few species of gecko on Marianne, including the La Digue day gecko (''Phelsuma sundbergi ladiguensis'') and ''Phelsuma astriata semicarinata''. Reportedly, the rare Seychelles paradise flycatcher (''Terpsiphone corvina'') is occasionally spotted on the island. Also, it was once home to the extinct Seychelles chestnut-sided white-ey ...

Felicite Island
Felicitas of Rome (c. 101 – 165), also anglicized as is a saint numbered among the Christian martyrs. Apart from her name, the only thing known for certain about this martyr is that she was buried in the Cemetery of Maximus, on the Via Salaria on a 23 November. However, a legend presents her as the mother of the seven martyrs whose feast is celebrated on 10 July. The Eastern Orthodox Church celebrates their martyrdom on 25 January. The legend of Saint Symphorosa is very similar and their acts may have been confused. She was a patron saint of healing. They may even be the same person. This Felicitas is not the same as the North African Felicitas who was martyred with Perpetua. History of Saint Felicitas The feast of Saint Felicitas of Rome was first mentioned in the ''"Martyrologium Hieronymianum"'' as celebrated on 25 January. From a very early date her feast as a martyr was solemnly celebrated in the Roman Church on that date, as shown by the fact that on that day Saint G ...
