Boehmantis
''Boehmantis'' is a genus of frogs in the mantellid subfamily Mantellinae. It is monotypic, being represented by a single species, ''Boehmantis microtympanum''. The genus is endemic to Madagascar. Taxonomy ''Boehmantis microtympanum'' was originally described in the genus ''Mantidactylus'' by Fernand Angel. The species was transferred to its own genus, ''Boehmantis'', by Frank Glaw and Miguel Vences. This was justified using molecular data as well as by the lack of femoral glands, which are present in all other species in the subfamily Mantellinae. Etymology The generic name honours , German herpetologist. Description ''Boehmantis microtympanum'' are relatively large frogs, with adults measuring in snout–vent length. The tympanum is rather indistinct and small. The finger and toe tips bear well-developed discs; the fingers have no webbing whereas the toes are fully webbed. Dorsal skin is smooth. The dorsal colouration varies from olive greenish to—especially in subadultsâ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mantellinae
Mantellinae is a subfamily of frogs in the family Mantellidae. These frogs are native to Madagascar and Mayotte. The species vary in size from under 25 mm (e.g. some species of '' Blommersia'') to over 100 mm (e.g. '' Mantidactylus guttulatus''). The subfamily is most famous for the genus '' Mantella'', which contains species that superficially resemble poison dart frogs of the tropical Americas, and have converged on similar aposematic colouration and toxins. As of 2 May 2016, there are 128 described species in this subfamily, but several more are described each year. Systematics Historically only two genera were recognized within the Mantellinae: '' Mantella'' and '' Mantidactylus''. Several subgenera were recognized within the genus ''Mantidactylus''. These were elevated to genus level in 2006 and are now universally accepted. These are '' Blommersia'', '' Boehmantis'', '' Gephyromantis'', '' Guibemantis'', '' Spinomantis'', and '' Wakea''.

Mantidactylus
''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 describe ...

Andohahela National Park
Andohahela National Park, in south-east Madagascar, is remarkable for the extremes of habitats that are represented within it. The park covers of the Anosy mountain range, the southernmost spur of the Malagasy Highlands and contains the last humid rainforests in the southern part of Madagascar. The Park was inscribed in the World Heritage Site in 2007 as part of the Rainforests of the Atsinanana. History Andohahela has been a protected area since 1939 but did not become a national park until 1998. Geography Andohahela National Park is north-west of Tôlanaro and at the southern end of the Malagasy Highlands. The park is divided into three zones. The first, Malio, ranges from to the summit of Pic d' Andohahela at , and has dense lowland and montane rainforest with more than two hundred species of tree ferns, orchids, wild vanilla, lemurs and many birds. The second, Ihazofotsy-Mangatsiaka, contains dry spiny forest with rare birds and reptiles in altitudes ranging from to at ...

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] |
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] |
Monotypic Amphibian Genera
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.' ...

Tsitongambarika
Tsitongambarika is a lowland forest in the north of Fort Dauphin (Madagascar), Fort-Dauphin, village Iabakoho, Anosy in southern Madagascar. The area supports many rare species of amphibians, birds, lemurs and reptiles; many of which are Endemism, endemic. In 2001, the site was designated as an Important Bird Area by BirdLife International and in 2015, an area of 600 km² received environmental protection by the government. The reserve is the recipient of monies raised by the British Birdwatching Fair, 2016 Rutland Birdfairin. Geography The forest is in the south of the island of Madagascar, within the Tsitongambarika massif, which consists of a series of ridges aligned from south-west to north-east. On the western boundary the Manampanihy river flows northwards. The nearest town is Tôlanaro, 9 km to the south. Tsitongambarika is the only area in the south of the country that still has significant areas of lowland forest but, due to illegal logging and shifting cultivatio ...

Habitat Destruction
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 reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance (height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as ''orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called "metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying objects such ...
