Spider
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 ...

Archaeidae
Archaeidae, also known as assassin spiders and pelican spiders, is a spider family with about ninety described species in five genera. It contains small spiders, ranging from long, that prey exclusively on other spiders. They are unusual in that they have "necks", ranging from long and slender to short and fat. The name "pelican spider" refers to these elongated jaws and necks used to catch their prey. Living species of Archaeidae occur in South Africa, Madagascar and Australia, with the sister family Mecysmaucheniidae occurring in southern South America and New Zealand. Assassin spiders were first known from 40 million year old amber fossils which were found in Europe in the 1840s, and were not known to have living varieties until 1881, when the first living assassin spider was found in Madagascar. The fossil record of this family was first identified from Baltic amber dating to the Eocene, although many taxa from these deposits have been reassigned to Mecysmaucheniidae, Malka ...

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] |
Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montagne D'Ambre National Park
Montagne d'Ambre National Park is a national park in the Diana Region of northern Madagascar. The park is known for its endemic flora and fauna, water falls and crater lakes. It is north of the capital, Antananarivo and is one of the most biologically diverse places in all of Madagascar with seventy-five species of birds, twenty-five species of mammals, and fifty-nine species of reptiles known to inhabit the park. Geography The park covers an area of on an isolated volcanic massif, of mostly basaltic rock, above the surrounding dry region. Attractions include spectacular waterfalls and several crater lakes. There are numerous rivers and streams and the park is a water catchment area for the town of Antsiranana, which is surrounded by dry, sparse forests and semi-desert with succulent plants. Annual rainfall in the park is compared with around the town. The area is named after the deposits of copal, a soft form of amber. Amber is one of the most accessible parks in northern M ...

Andriamanelo
Andriamanelo (Floruit, ''fl.'' 1540–1575) was king of Twelve sacred hills of Imerina#Hill of Alasora, Alasora in the central highlands region of Madagascar. He is generally considered by historians to be the founder of the Kingdom of Imerina and originator of the Merina royal line that, by the 19th century, had extended its rule over virtually all of Madagascar. The son of a Vazimba mother and a man of the newly arrived Hova (Madagascar), Hova people originating in Anosy, southeast Madagascar, Andriamanelo ultimately led a series of military campaigns against the Vazimba, beginning a several-decade process to drive them from the Highlands. The conflict that defined his reign also produced many lasting innovations, including the development of fortified villages in the highlands and the use of iron weapons. Oral tradition furthermore credits Andriamanelo with establishing a ruling class of nobles (''andriana'') and defining the rules of succession. Numerous cultural tradition ...

Merina Kingdom
The Merina Kingdom, or Kingdom of Madagascar, officially the Kingdom of Imerina (–1897), was a pre-colonial state off the coast of Southeast Africa that, by the 19th century, dominated most of what is now Madagascar. It spread outward from Imerina, the Central Highlands region primarily inhabited by the Merina ethnic group with a spiritual capital at Ambohimanga and a political capital west at Antananarivo, currently the seat of government for the modern state of Madagascar. The Merina kings and queens who ruled over greater Madagascar in the 19th century were the descendants of a long line of hereditary Merina royalty originating with Andriamanelo, who is traditionally credited with founding Imerina in 1540. In 1883, France invaded the Merina Kingdom to establish a protectorate. France invaded again in 1894 and conquered the kingdom, making it a French colony, in what became known as the Franco-Hova Wars. History Hova-Vazimba conflict Madagascar's central highlands w ...
