Mantellidae
The Mantellidae are a family of the order Anura. These frogs are endemic to the islands of Madagascar and Mayotte. Systematics The family Mantellidae is composed of three extremely ecologically diverse groups of frogs, divided into three subfamilies: the Mantellinae Laurent, 1946 are typically terrestrial or semi-aquatic frogs; the Laliostominae Vences & Glaw, 2001 are terrestrial, typically fairly large-sized frogs; and the Boophinae Vences & Glaw, 2001 are arboreal tree frogs. Apart from the genera assigned to the three subfamilies, the placement of '' Tsingymantis'' Glaw, Hoegg & Vences, 2006 is still uncertain. As of 22 September 2022, 237 species are recognized in this family. DNA barcoding research has shown however that more than 100 distinct genetic lineages remain taxonomically undescribed. Evolution and island biogeography The Mantellidae are Madagascar's most diverse frog family. It has been shown that there is a negative correlation between body size ...

Miguel Vences
Professor Miguel Vences (born 24 April 1969 in Cologne) is a German herpetologist and evolutionary biologist. Much of his research is focused on the reptiles and amphibians of Madagascar. Life The son of Galician philosopher Sergio Vences Fernández (1936–2012), Vences attended the Schiller-Gymnasium Köln from 1979 to 1988, and graduated with the German Abitur. The following year he began to study Biology at the University of Cologne. There he met Frank Glaw, and as undergraduate students they undertook their first excursions to Madagascar. 496 pp. After completing the Vordiplom in 1993, Vences transferred to the University of Bonn and the Museum König, where he completed his Diplom studies. Vences continued his studies there as a PhD student under the supervision of Wolfgang Böhme until 2000. His thesis was on the evolutionary history of true frogs (Ranoidea) and related families in Madagascar. Thereafter, he worked for one year at the National Museum of Natural Histo ...

Genera
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below 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 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 of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demons ...

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...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 ...

Aglyptodactylus
''Aglyptodactylus'' is a genus of frogs in the family Mantellidae. These frogs, sometimes known as the Madagascar jumping frogs, are endemic to Madagascar. Systematic revisions of the groups were published in 1998 and 2015. Six species are currently recognized. Description ''Aglyptodactylus'' are medium-sized frogs as adults, measuring in snout–vent length. Tadpoles All ''Aglyptodactylus'' species have small, morphologically similar tadpoles that metamorphose at a size of . However, they differ in their habitat, ranging from ephemeral pools (''Aglyptodactylus laticeps'') to river bed pools (''Aglyptodactylus securifer'') to stagnant pools ('' Aglyptodactylus madagascariensis''). The tadpoles are detritivorous. Species There are six ''Aglyptodactylus'' species: * ''Aglyptodactylus australis'' Köhler, Glaw, Pabijan & Vences, 2015 * ''Aglyptodactylus chorus'' Köhler, Glaw, Pabijan & Vences, 2015 * '' Aglyptodactylus inguinalis'' (Günther, 1877) * ''Aglyptodactylus laticeps'' ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda. ...

Tetrapod Subfamilies
Tetrapods (; ) are four-limb (anatomy), limbed vertebrate animals constituting the superclass Tetrapoda (). It includes extant taxon, extant and extinct amphibians, sauropsids (reptiles, including dinosaurs and therefore birds) and synapsids (pelycosaurs, extinct therapsids and all extant mammals). Tetrapods evolved from a clade of primitive semiaquatic animals known as the Tetrapodomorpha which, in turn, evolved from ancient lobe-finned fish (sarcopterygians) around 390 million years ago in the Middle Devonian, Middle Devonian period; their forms were transitional between lobe-finned fishes and true four-limbed tetrapods. Limbed vertebrates (tetrapods in the broad sense of the word) are first known from Middle Devonian trackways, and body fossils became common near the end of the Late Devonian but these were all aquatic. The first crown group, crown-tetrapods (last common ancestors of extant tetrapods capable of terrestrial locomotion) appeared by the very early Mississippian ( ...

Taxa Named By Frank Glaw
In biology, a taxon (back-formation from ''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 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 system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
