Mantidactylus Grubenmanni
''Mantidactylus'' is a frog genus in the mantellid subfamily Mantellinae. This genus is restricted to Madagascar. The genus is divided into several subgenera that form monophyletic genetic clusters and are ecologically similar. Taxonomy ''Mantidactylus'' was erected by Boulenger in 1895 with the type species '' Rana guttulata''. For a long time the genus contained a wide variety of mostly terrestrial Madagascan frogs, that were divided into species groups and/or subgenera. Several of these groups were subsequently erected to genus level: ''Blommersia'', ''Boehmantis'', ''Gephyromantis'', ''Guibemantis'', ''Spinomantis'' and '' Wakea''. Today, six subgenera remain within the genus ''Mantidactylus'': *''Mantidactylus'' Boulenger, 1895 *'' Hylobatrachus'' Laurent, 1943 *'' Brygoomantis'' Dubois, 1992 *'' Ochthomantis'' Glaw & Vences, 1994 *'' Chonomantis'' Glaw & Vences, 1994 *'' Maitsomantis'' Glaw & Vences, 2006 Species New species of ''Mantidactylus'' are described ...

Oskar Boettger
Oskar Boettger (german: Böttger; 31 March 1844 – 25 September 1910) was a German zoologist who was a native of Frankfurt am Main. He was an uncle of the noted malacologist Caesar Rudolf Boettger (1888–1976).

Mantidactylus Ulcerosus
''Mantidactylus ulcerosus'' is a species of frog in the family Mantellidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, rivers, swamps, freshwater marshes, intermittent freshwater marshes, and heavily degraded former forest. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ....

Andolalao Rakotoarison
Andolalao Rakotoarison (born 1982 in Mahajanga) is a Malagasy herpetologist. Life and research Rakotoarison conducted her Master's thesis at the University of Antananarivo in 2011. She then conducted her PhD at the Technical University of Braunschweig on the systematics of the frogs of the Madagascar-endemic narrow-mouthed frog subfamily Cophylinae, under the supervision of Professor Miguel Vences. As of mid-2020, she has co-authored the description of 52 frog species and two reptiles (one gecko and one chameleon). In particular, Rakotoarison has contributed to knowledge of Madagascar's smallest frogs. In 2017, she led a study published as a monograph with sixteen other coauthors, describing 26 new species of the genus '' Stumpffia'', including several frogs that number among the smallest in the world, and in 2020, she was also involved in the description of five more miniaturised frogs, including the new genus ''Mini The Mini is a small, two-door, four-seat car, dev ...

Mantidactylus Radaka
''Mantidactylus radaka'' is a species of frog in the Family (biology), family Mantellidae. It is Endemism, endemic to Madagascar. It was described in 2020 by an international team of scientists, who differentiated it from ''Mantidactylus guttulatus, M. guttulatus'' and Mantidactylus grandidieri, ''M. grandidieri'' via molecular data from wild and museum specimens. The Specific name (zoology), specific name is based on the Malagasy language, Malagasy word for "large frog" (as opposed to ''sahona'', "small frog"), which is often used as a common name for the species. It is frequently hunted and eaten by local people. Its natural habitats are calm, shallow streams in rainforests. Its conservation status has not yet been evaluated by the IUCN.

François Mocquard
François Mocquard (27 October 1834 – 19 March 1917) was a French herpetologist born in Leffond, Haute-Saône. In 1860 he was named ''préparateur du physique'' after receiving his Bachelor of Science degree at the Faculty of Besançon. Subsequently, he earned degrees in physical sciences (1862), mathematical sciences (1865) and medicine (1873). Despite being middle-aged, he made a career change, and began studying natural sciences in the laboratory of Alphonse Milne-Edwards (1835-1900) at the Muséum national d'histoire naturelle in Paris. In 1884 he earned his doctorate of sciences with a thesis on the structure of the stomach in crustaceans, afterwards working as an assistant in the ichthyology and herpetology department at the museum. During his career he described numerous herpetological taxa, most notably species from Madagascar, Tonkin, Borneo, Mexico and Central America. In addition, he has several species named after him, including reptiles, '' Alluaudina mocquardi'', ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
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 ...
