Boulengerula Denhardti
''Boulengerula denhardti'' (Denhardt's African caecilian) is a species of amphibian in the family Herpelidae. It is endemic to Kenya. It is only known from its type locality, the Tana River valley, as well as from the Ngaia Forest, Meru County. It is named for German explorer brothers Clemens Denhardt and Gustav Denhardt who explored the area where it was discovered. Its natural habitats are subtropical or tropical moist lowland forests 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 ..., expanding agriculture, use of herbicides and pesticides and expanding human settlements.

Amphibian
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herpelidae
Herpelidae are a family of caecilians, sometimes known as the African caecilians. They are found in Sub-Saharan Africa. Like other caecilians, they superficially resemble worms or snakes. They are the sister group to the newly discovered Chikilidae. Distribution Herpelidae occur primarily in Central and East Africa, barely reaching West Africa (southeastern Nigeria), and northern parts of Southern Africa (Malawi, possibly Zambia). Genera There are two genera with ten species in total: * ''Boulengerula'' Tornier, 1896 – Boulenger's caecilians, Usambara bluish-gray caecilians (8 species) * ''Herpele ''Herpele'' is a genus of caecilians in the family Herpelidae.

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] |

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Tana River (Kenya)
The ca. 1000 km long Tana River is the longest river in Kenya, and gives its name to the Tana River County.Nakaegawa T., Wachana C. and KAKUSHIN Team-3 Modeling Group. (2012). "First impact assessment of hydrological cycle in the Tana River Basin, Kenya, under a changing climate in the late 21st Century,''Hydrological Research Letters'', 6, pp. 29-34 Its catchment covers ca. 100,000 km² and can be divided into the headwaters and the lower Tana consisting of the section downstream of Kora where the river flows for ca. 700 km through semi-arid plains. Its tributaries include the Thika, Ragati River from Mt.Kenya as well as several smaller rivers that flow only during the rainy season. The river rises in the Aberdare Mountains to the west of Nyeri. Initially it runs east before turning south around the massif of Mount Kenya. A series of hydroelectric dams (the Seven Forks Hydro Stations or the Seven Forks Scheme) has been constructed along the river. These include (in or ...

Clemens Denhardt
Clemens Andreas Denhardt (1852–1928) and his brother Gustav Denhardt (1856–1917), born in Zeitz, Province of Saxony, were distinguished German explorers of Africa at the time of the Scramble for Africa. In association with the physician G. A. Fischer they undertook in 1878 a tour through the Tana River region, East Africa, which they endeavored to secure to German commerce. Six years later they entered upon a second expedition, extending from the island Lamu to Vitu (March, 1885), where the Sultan of the Swahili requested the establishment of a friendly treaty with Germany based upon proposals made by him 18 years previously. Part of the territory acquired by Clemens Denhardt was afterward transferred by him to the German colonial society known as the '' Deutsche Witugesellschaft''. In 1890 all rights to this territory were ceded by Germany to England in exchange for Helgoland, the German government compensating the brothers with an indemnity of 150,000 Goldmark. ...

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 ...

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 ...
