Anilany
''Anilany helenae'' is a species of frog in the microyhlid subfamily Cophylinae. It is the only species in the monotypic genus ''Anilany'', and is endemic to central Madagascar. Taxonomy This species was originally described by Denis Vallan in 2000 as a member of the genus '' Stumpffia''. It was transferred to the genus '' Rhombophryne'' by Peloso et al. in 2016 when they synonymised ''Stumpffia'' with that genus, but was then moved to the newly erected genus ''Anilany'' by Scherz et al. due to its genetic relationships and because it differs significantly in aspects of its morphology (the shape of the vomer, clavicles, and terminal phalanges of the fingers and toes). Habitat and Ecology Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss. It now occurs in a few strips of fragmented habitat Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), cau ...

Stumpffia
''Stumpffia'' is a genus of microhylid frogs that are endemic to Madagascar. They are mostly brown frogs that typically live among leaf litter. ''S. contumelia'' has a snout–vent length of about , making it one of the world's smallest frogs, and several others in the genus are only slightly larger. The largest species is no more than . The majority of the species have only been described since 2010. Each species has a small range and many are seriously threatened. Taxonomy ''Stumpffia'' was first described from the single species '' Stumpffia psologlossa'' Boettger, 1881, based on a single specimen collected on Nosy Be, a large island off the northwest coast of Madagascar, by Anotonio Stumpff. By 2017, 15 species were recognised. In late 2017, a major revision of the genus was published. This study used integrative taxonomy, i.e. the combination of multiple different datasets, to delimit and describe new species: it combined morphological, morphometric, chromatic (color ...

Cophylinae
Cophylinae is a subfamily of Microhylidae, microhylid frogs endemic to Madagascar. It has over 100 species in eight genera. Members of this subfamily range from minute ( 100 mm adult body size), and they are highly ecologically diverse. DNA barcoding, DNA barcode research has revealed a significant taxonomic gap in this subfamily, and an estimated 70+ candidate species were identified. Many of these have subsequently been described, as well as numerous new discoveries (e.g. 26 species of ''Stumpffia'' described in 2017). Genera As of December 2019, the following genera are recognised in the subfamily Cophylinae: * ''Anilany'' Scherz, Miguel Vences, Vences, Andolalao Rakotoarison, Rakotoarison, Andreone, Köhler, Frank Glaw, Glaw & Crottini, 2016 (Monotypic taxon, monotypic) * ''Anodonthyla'' Müller, 1892 (12 species) * ''Cophyla'' Oskar Boettger, Boettger, 1880 (21 species) * ''Madecassophryne'' Guibé, 1974 (Monotypic taxon, monotypic) * ''Mini (frog), Mini'' Scherz, Hutte ...

Microhylidae
The Microhylidae, commonly known as narrow-mouthed frogs, are a geographically widespread family of frogs. The 683 species are in 63 genera and 11 subfamilies, which is the largest number of genera of any frog family. Evolution A molecular phylogenetic study by van der Meijden, et al. (2007) has estimated the initial internal divergence of the family Microhylidae to have taken place about 66 million years ago, or immediately after the Cretaceous extinction event. The most recent common ancestor of the Microhylidae and their closest ranoid relatives is estimated to have lived 116 million years ago in Gondwana. Description As suggested by their name, microhylids are mostly small frogs. Many species are below in length, although some species are as large as . They can be arboreal or terrestrial, and some even live close to water. The ground-dwellers are often found under leaf litter within forests, occasionally venturing out at night to hunt. The two main shapes for the microhyli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhombophryne
''Rhombophryne'' is a genus of microhylid frogs endemic to Madagascar. It is currently estimated to include more than 23 species, but only 20 of these are currently described. The common name 'diamond frog' has been proposed and used for members of this genus. Taxonomy The genus ''Rhombophryne'' was monotypic until 2005, containing just '' R. testudo'' Boettger, 1880. However, in 2005 Andreone et al. showed that the genus '' Plethodontohyla'' was paraphyletic with respect to this genus. Several species were therefore transferred to this genus by Frost et al. in 2006, Glaw and Vences in 2007, and Wollenberg et al. in 2008. In 2015/2016, Peloso et al. re-analysed the genetic relationships of the Microhylidae using partial genomic data. They proposed the synonymy of '' Stumpffia'' with ''Rhombophryne'' because these genera were found to be paraphyletic. However, in 2016 Scherz et al. re-analysed their data with new data—including osteology and external morphology. They found ...

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 ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Taxa Named By Angelica Crottini
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] |
