Calumma Tsaratananense
''Calumma tsaratananense'', the Tsaratanana chameleon, is a species of chameleon found in 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 .... Range and habitat ''Calumma tsaratananense'' is known only from the Tsaratanana Massif, Madagascar's highest mountain, located in the northern portion of the island. It inhabits high-elevation heathland between 2,500 and 2,850 meters elevation in the ericoid thickets ecoregion. Its area of occupancy (AOO) is not well known. Tsaratanana Massif has an area of 492 km2, but the chameleon's range is less than less than 100 km6, and may be as little as 6 km2.

Charles Domergue
Charles Antoine Domergue (5 January 1914 in Besançon, France – 31 December 2008 in Antananarivo) was a French naturalist, ornithologist, herpetologist, spelunker and geologist who spent much of his life in Madagascar. He also dealt with the effects of pollution. Eponyms Domergue is commemorated in the scientific name of a species of snake, ''Madatyphlops domerguei'', and a frog, '' Blommersia domerguei'', both of which are endemic to Madagascar.

Chameleon
Chameleons or chamaeleons (family Chamaeleonidae) are a distinctive and highly specialized clade of Old World lizards with 202 species described as of June 2015. The members of this family are best known for their distinct range of colors, being capable of shifting to different hues and degrees of brightness. The large number of species in the family exhibit considerable variability in their capacity to change color. For some, it is more of a shift of brightness (shades of brown); for others, a plethora of color-combinations (reds, yellows, greens, blues) can be seen. Chameleons are distinguished by their zygodactylous feet, their prehensile tail, their laterally compressed bodies, their head casques, their projectile tongues, their swaying gait, and crests or horns on their brow and snout. Chameleons' eyes are independently mobile, and because of this there are two separate, individual images that the brain is analyzing of the chameleon’s environment. When hunting prey, they ...

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 ...

Tsaratanana Massif
Madagascar is a large island in the Indian Ocean off the eastern coast of southern Africa, east of Mozambique. It has a total area of with of land and of water. Madagascar is the fourth largest island and the 2nd largest island country in the world. The highest point is Maromokotro, in the Tsaratanana Massif region in the north of the island, at . The capital Antananarivo is in the Central Highlands near the centre of the island. It has the 25th largest Exclusive Economic Zone of . Madagascar is 400 kilometres (250 miles) east of mainland Africa. Geographical regions Madagascar can be divided into five general geographical regions: the east coast, the Tsaratanana Massif, the Central Highlands, the west coast, and the southwest. The highest elevations parallel the east coast. The total size is , which makes it the world's second largest island country. East coast The east coast consists of a narrow band of lowlands about fifty kilometers wide, formed from the sedimentatio ...

Madagascar Ericoid Thickets
The Madagascar ericoid thickets is a montane shrubland ecoregion, found at higher altitudes on Madagascar's four major mountains. Geography The ecoregion covers the area above 1800 m elevation on (from north to south) Tsaratanana (2,876 m), Marojejy (2,133 m), Ankaratra (2,643 m), and Andringitra Massif (2,658 m). The ericoid thickets are surrounded at lower elevations by the Madagascar subhumid forests ecoregion. The total area of the ecoregion is . On Tsaratanana the thickets are higher up, starting above 2,500m. There are smaller areas of thicket in Anjanaharibe-Sud Special Reserve in the north and Andohahela National Park to the south. Flora The main plant community is thickets. The thickets are composed of evergreen woody shrubs and low trees, which form a single, often impenetrable stratum never more than 6 meters tall. The shrubs and trees typically have an ericoid habit, with short, twisted stems and ericoid, cupressoid, or myrtilloid leaves.White, Frank F. (1983). ''The ...

Area Of Occupancy
Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or ''plane area'' refers to the area of a shape or planar lamina, while '' surface area'' refers to the area of an open surface or the boundary of a three-dimensional object. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analogue of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept). The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (written as m2), which is the area of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such squares. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calumma
''Calumma'' is a genus of chameleons endemic and restricted to Madagascar. The species formerly named ''Calumma tigris'' was transferred to the genus '' Archaius'' by Townsend et al., when they found that it is more closely related to ''Rieppeleon'' than to ''Calumma''. The oldest fossil of the genus is known from the Early Miocene of Kenya, showing that the genus originated in Africa. Species groups Four species groups are recognised within the genus ''Calumma'' (originally proposed by Glaw & Vences in 1994), some of which may be only phenetic, while others are phylogenetically supported: ''Calumma furcifer'' species group Contents: ''Calumma furcifer, C. gastrotaenia, C. marojezense, C. guillaumeti, C. andringitraense, C. glawi, C. vencesi'' Species characterised by typically green body colouration, sleek body form, and generally no occipital lobes (flaps of skin posterior to the head; present only in ''C. glawi'') and no rostral appendage (present only in males of ''C. furc ...

Reptiles Of Madagascar
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates ( lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated ...

Taxa Named By Édouard-Raoul Brygoo
In biology, a taxon (back-formation from ''Taxonomy (biology), taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular Taxonomic rank, ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of bio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
