Gephyromantis Malagasius
''Gephyromantis malagasius'', commonly known as the Malasay grainy frog, is a species of frog in the family Mantellidae. It is endemic to Madagascar. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. 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 ....

Paul Ayshford Methuen
Paul Ayshford Methuen, 4th Baron Methuen (29 September 1886 – 7 January 1974) was a painter, zoologist and landowner. Life From 1910 to 1914 he worked in the Transvaal Museum in Pretoria, where he published several scientific papers with the South African herpetologist, John Hewitt, with whom he collected and described a number of southern African and Madagascan genera and species in the early 20th century. He later refused a chair in zoology at a South African university because of his commitment to his ancestral home. Methuen had studied drawing at Eton, at the Ruskin in Oxford, and with Charles Holmes. In 1927 he attended art classes given by Walter Sickert, which had a permanent effect on his painting style. He established a reputation as a serious artist. His preferred subjects were urban views and outdoor scenes with buildings, animals, and plants, such as the magnolias and orchids he grew at Corsham Court. In 1939 he rejoined his regiment and served as a captain u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Hewitt (herpetologist)
John Hewitt (23 December 1880 – 4 August 1961) was a South African zoologist and archaeologist of British origin. He was born in Dronfield, Derbyshire, England, and died in Grahamstown, South Africa. He was the author of several herpetological papers which described new species. He also described new species of spiders and other arachnids. Biography He graduated with a first-class in natural sciences from Jesus College, Cambridge in 1903. From 1905 to 1908 he was Curator of the Sarawak Museum in Kuching, Sarawak.

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] |
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 ...

Endemism
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] |
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 ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

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] |
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 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 ...

Gephyromantis
''Gephyromantis'' is a frog genus in the mantellid subfamily Mantellinae. This genus is restricted to Madagascar. At present it contains 45 species divided into six subgenera. Taxonomy The genus ''Gephyromantis'' was erected by Methuen in 1920 for the species '' Gephyromantis boulengeri''. Blommers-Schlösser considered this group as a subgenus of ''Mantidactylus ''Mantidactylus'' is a frog genus in the mantellid subfamily Mantellinae. This genus is restricted to Madagascar.
