Mantella Madagascariensis
''Mantella madagascariensis'', common names Malagasy painted mantella, Madagascan mantella, Madagascar golden frog, Malagasy mantella and painted mantella, is a species of frog in the family Mantellidae. Distribution This species is endemic to Madagascar. It is present in the East-central Madagascar in upland locations from near Niagarakely south to Ranomafana, at an elevation of above sea level. It is threatened by habitat loss and it may be threatened by commercial collection. Habitat Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and rivers.Andreone, F. & Glaw, F. 2004.Mantella madagascariensis2006 IUCN Red List of Threatened Species Description ''Mantella madagascariensis'' can reach a body length of in males, of in females. These tiny but stout frogs are rather variable in color and markings, as they are irregularly streaked in black and yellow. Usually they have a blackish body, but the dorsum is co ...

Alfred Grandidier
Alfred Grandidier (20 December 1836 – 13 September 1921) was a French naturalist and explorer. From a very wealthy family, at the age of 20, he and his brother, Ernest Grandidier (1833–1912), undertook a voyage around the world. At first they were led by the astronomer and physicist Pierre Jules César Janssen (1824–1907), but when Janssen fell sick and had to return to France after about six months, the brothers continued the journey. They visited South America in 1858 and 1859 and in particular the Andes, Peru, Chile, Bolivia, Argentina and Brazil. During this voyage they gathered a significant collection of specimens which were analyzed, in 1860, by Ernest. The two brothers parted ways after this. Ernest Grandidier went to China and collected a vast number of specimens which are now in the Louvre and the Guimet museum. Alfred travelled to India, reaching it in 1863. He had intended to explore the high plateau of Tibet, but was prevented by a severe attack of fever. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as Stream#Creek, creek, Stream#Brook, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to Geographical feature, geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "Burn (landform), burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from Precipitation (meteorology), precipitation through a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...

Species Endangered By The Pet Trade
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 in zoological ...

Endemic Frogs Of Madagascar
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] |
Mantella
''Mantella'' (also known as golden frogs or Malagasy poison frogs) are a prominent genus of aposematic frogs in the family Mantellidae, endemic to the island of Madagascar. Members of ''Mantella'' are diurnal and terrestrial, with bright aposematic coloration or cryptic markings. Natural history ''Mantella'' are an example of convergent evolution—the independent evolution of a similar trait with species of a different lineage—with the Latin American family Dendrobatidae in size, appearance, and some behavioral characteristics. During the description of the first specimens from 1866 to 1872, Alfred Grandidier described both the brown mantella (''Mantella betsileo'') and Malagasy mantella (''Mantella madagascariensis'') and placed them within the genus ''Dendrobates'' based on their close resemblance. This placement was heavily debated until 1882, when George Albert Boulenger created the genus ''Mantella'' after describing both Cowan's mantella (''Mantella cowanii'') and ...
