Palleon Nasus
''Palleon nasus'', commonly known as the elongate leaf chameleon, is a species of chameleon endemic to Madagascar. It was initially described by Boulenger in 1887. The species contains two subspecies, ''P. n. nasus'' and ''P. n. pauliani''. It grows no more than 9 cm. Distribution and habitat ''Palleon nasus nasus'' is endemic to Ekongo, south-eastern Madagascar, and its geological type locality is Ekongo, southeastern Madagascar. ''P. n. pauliani'' is only known from its type locality of Manjarivolo, l’Andringitra, Madagascar. ''P. n. pauliani'' can be found at elevations between above mean sea level. ''P. nasus'' was listed by the IUCN as a vulnerable species, as it can be found over an area of , but the quality and extent of the humid forest where the species needs to live is in a continuous decline, mainly due to mining, logging (for charcoal), and the slash-and-burn method in agriculture. ''P. n. nasus'' is found in some strictly protected areas and reserves, meaning it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palleon Lolontany
''Palleon lolontany'' is a species of chameleon endemic to Madagascar. It was first described by Raxworthy and Nussbaum in 1995 as ''Brookesia lolontany''. It was since placed in the genus ''Palleon'' when that genus was erected in 2013. The International Union for Conservation of Nature (IUCN) rated the species as Near Threatened. Distribution and habitat ''Palleon lolontany'' is endemic to Mount Tsaratanana (Maromokotro), Madagascar's highest mountain, on the Tsaratanana Massif. Its type locality is Matsabory Lake and Mount Tsaratanana at above mean sea level. Currently, ''P. lolontany'' specimens can be found between in one humid Tsaratanana forest, over an area of , the estimated size of suitable habitat in Tsaratanana for the species. At the most, the species can be found over an area of . It is listed as Near Threatened because it is only found at most in 468 square km, and if the slash-and-burn method of agriculture were used, the species would continue to decline in n ...

Chameleons
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 ...

Frank Glaw
Frank Rainer Glaw (born 22 March 1966 in Düsseldorf) is a German herpetologist working at the Zoologische Staatssammlung München. Glaw studied biology in Cologne from 1987, where he completed his diploma. Thereafter, he attended the University of Bonn, from which he graduated in 1999, after completing his Ph.D. thesis titled ''Untersuchungen zur Bioakustik, Systematik, Artenvielfalt und Biogeographie madagassischer Anuren'' about the frogs of Madagascar, supervised by Professor Wolfgang Böhme. Since 1997, he has been the curator of herpetology at the Zoologische Staatssammlung München. Glaw's focus during and after his thesis work was the herpetofauna of Madagascar. Since the end of the 1980s, he has been working closely with Miguel Vences, currently professor for evolutionary biology and zoology at the Technische Universität Braunschweig. Together, they published ''A Field Guide to the Amphibians and Reptiles of Madagascar'' in 1992, a benchmark work on the amphibians and ...

George Albert Boulenger
George Albert Boulenger (19 October 1858 – 23 November 1937) was a Belgian-British zoologist who described and gave scientific names to over 2,000 new animal species, chiefly fish, reptiles, and amphibians. Boulenger was also an active botanist during the last 30 years of his life, especially in the study of roses. Life Boulenger was born in Brussels, Belgium, the only son of Gustave Boulenger, a Belgian public notary, and Juliette Piérart, from Valenciennes. He graduated in 1876 from the Free University of Brussels with a degree in natural sciences, and worked for a while at the Royal Belgian Institute of Natural Sciences, Brussels, as an assistant naturalist studying amphibians, reptiles, and fishes. He also made frequent visits during this time to the ''Muséum national d'Histoire naturelle'' in Paris and the British Museum in London. In 1880, he was invited to work at the Natural History Museum, then a department of the British Museum, by Dr. Albert C. L. G. Günther a ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Brookesia
''Brookesia'' is a genus of chameleons, endemic to Madagascar, that range from small to very small in size, and are known collectively as leaf chameleons (though this name also commonly is used for species in the genera ''Rieppeleon'' and ''Rhampholeon''). ''Brookesia'' includes species considered to be the world's smallest chameleons, and are also among the smallest reptiles. Members of the genus ''Brookesia'' are largely brown and most are essentially terrestrial. A significant percentage of the species in the genus were only identified to science within the last three decades, and a number of species that still have not received a scientific name are known to exist. Most inhabit very small ranges in areas that are difficult to access, and due to their small size and secretive nature, they have been relatively poorly studied compared to their larger relatives. ''Brookesia'' are abundant in low-disturbance riparian zones and low-disturbance rainforests. ''Brookesia'' are scar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 ...
