Amber Mountain 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 ...

Lorenz Müller
Lorenz Müller (18 February 1868 in Mainz – 1 February 1953 in Munich) was a German herpetologist. Professor Lorenz Müller was known for his studies on the Balearic Islands species of the genus ''Podarcis'' (wall lizards) during the 1920s, in which he described several new subspecies, including the now extinct Ratas Island lizard, ''Podarcis lilfordi rodriquezi''. Together with his colleague Professor Robert Mertens he made several studies about European amphibians and reptiles. Lorenz Müller died at 85 from a bronchitis. A species of South American lizard, ''Liolaemus lorenzmuelleri ''Liolaemus lorenzmuelleri'', commonly known as Lorenz's tree iguana, is a species of lizard in the family Iguanidae.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Nosy Be
Nosy Be (formerly Nossi-bé and Nosse Be) is an island off the northwest coast of Madagascar. Nosy Be is Madagascar's largest and busiest tourist resort. It has an area of , and its population was 109,465 according to the provisional results of the 2018 Census. ''Nosy Be'' means "big island" in the Malagasy language. The island was called Assada during the early colonial era of the 17th century. Nosy Be has been given several nicknames over the centuries, including "Nosy Manitra" (the scented island). History The first human inhabitants of Nosy Be were small bands of Antankarana and Zafinofotsy, before the Sakalava people migrated there and became the most numerous ethnic group on the island. These people were joined later by some Comorians, Indians or Antandroy. Nosy Be made first major appearance in Madagascar's history when King Radama I announced that he intended to conquer the whole west of Madagascar. That plan was eventually achieved in 1837 when the Sakalava Kingdom of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Hemipenis
A hemipenis (plural hemipenes) is one of a pair of intromittent organs of male squamates (snakes, lizards and worm lizards). Hemipenes are usually held inverted within the body, and are everted for reproduction via erectile tissue, much like that in the human penis. They come in a variety of shapes, depending on species, with ornamentation, such as spines or hooks. The female homologue is the hemiclitoris. Background The hemipenis is the intromittent organ of squamata, which is the second largest order of vertebrates with over 9000 species distributed around the world. They differ from the intromittent organs of most other amniotes such as mammals, archosaurs and turtles that have a single genital tubercle, as squamates have the paired genitalia remaining separate. Squamate hemipenes also develop from a different cell origin, originating from the same embryonic cells that produce the limbs, whereas mammalian penises arise from the embryonic cells that develop the tail.

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 ...
