Phrynobatrachus Keniensis
''Phrynobatrachus keniensis'' is a species of frog in the family Phrynobatrachidae. It is found widely in the highlands of Kenya ( Cherang'any Hills in the northwest, Nyambene Hills in the northeast, and from several locations in the Central Highlands, for example from Mount Kenya and the Aberdare Range). It is also recorded from Mount Meru in northern Tanzania, but this might represent a different species. Common names Kenya River frog and upland puddle frog have been coined for it. Description ''Phrynobatrachus keniensis'' are small frogs; males reach a snout–vent length of no more than and females no more than . The overall appearance is stout. The head is as long as it is broad. The snout is rounded or very obtusely pointed. There is a characteristic skin fold at the anterior end of the upper eyelid. The tympanum is hidden. The fingers have no webbing whereas the toes have moderate webbing. The finger and toe tips are not dilated. Skin is smooth but there are some indicat ...

Thomas Barbour
Thomas Barbour (August 19, 1884 – January 8, 1946) was an American herpetologist. From 1927 until 1946, he was director of the Harvard Museum of Comparative Zoology (MCZ) founded in 1859 by Louis Agassiz at Harvard University in Cambridge, Massachusetts. Life and career Barbour, the eldest of four brothers, was born in 1884 to Colonel William Barbour, and his wife, Julia Adelaide Sprague. Colonel Barbour was founder and president of The Linen Thread Company, Inc., a successful thread manufacturing enterprise having much business in the United States, Ireland, and Scotland. Although born on Martha's Vineyard, Massachusetts, where the family was spending the summer, Barbour grew up in Monmouth, New Jersey, where one of his younger brothers, William Warren Barbour, entered the political arena, eventually serving as U.S. Senator from New Jersey from 1931 to 1937 and again from 1938 to 1943. At age fifteen, Thomas Barbour was taken to visit Harvard University, which, entranced by ...

Overgrazing
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change. Overgrazing can be reversed or prevented by removing grazers in order to give plants time to recover between grazing events. Successful planned grazing strategies have been support in the American bison of the Great Plains, or migratory Wildebeests of the African savann ...

Taxa Named By Arthur Loveridge
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 intro ...

Amphibians Of Tanzania
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within 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 recent decades there has been a dramatic decline ...

Frogs Of Africa
The fauna of Africa, in its broader sense, is all the animals living in Africa and its surrounding seas and islands. The more characteristic African fauna is found in the Afrotropical realm. Lying almost entirely within the tropics, and equally to north and south of the equator creates favourable conditions for rich wildlife. Africa is home to many of the world's most famous fauna in human culture such as lions‚ rhinos‚ cheetahs‚ giraffes‚ antelope, hippos, leopards, zebras‚ and African elephants among many others. Origins and history of African fauna Whereas the earliest traces of life in fossil record of Africa date back to the earliest times, the formation of African fauna as we know it today, began with the splitting up of the Gondwana supercontinent in the mid-Mesozoic era. After that, four to six faunal assemblages, the so-called African Faunal Strata (AFSs) can be distinguished. The isolation of Africa was broken intermittently by discontinuous "filter routes" tha ...

Phrynobatrachus
''Phrynobatrachus'' is a genus of Sub-Saharan frogs that form the monogeneric family Phrynobatrachidae. Their common name is puddle frogs, dwarf puddle frogs, African puddle frogs, or African river frogs. The common name, puddle frog, refers to the fact that many species breed in temporary waterbodies such as puddles. ''Phrynobatrachus'' are among the most common amphibians in Africa. They are typically small (mostly less than ), fast-moving frogs. They occupy a variety of habitats from dry savannas to rainforests. Most species deposit many small eggs as a surface clutch in standing or slowly moving water and have exotrophic tadpoles. Taxonomy Phrynobatrachidae has earlier been considered as a subfamily of Ranidae, but its recognition as a family is now well-established. It is probably most closely related to Petropedetidae and Pyxicephalidae or Ptychadenidae. This large genus may be further divided into three major clades. These clades could be treated as different genera, b ...

Endemic Fauna Of Kenya
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 s ...

Mount Kenya National Park
Mount Kenya National Park was established in 1949 to protect Mount Kenya, the wildlife and surrounding environment, which forms a habitat for wilderness, wild animals, as well as acting as an area for the catchment of water, to supply Kenya's water. History Initially, it was a forest reserve, before being announced as a national park. Currently, the national park is encircled by the forest reserve. In April 1978, the area was designated a UNESCO Biosphere Reserve. Combined, the national park and forest reserve became a UNESCO World Heritage Site in 1997. The Politics of Kenya, Government of Kenya had four reasons for creating a national park on and around Mount Kenya. These were the importance of tourism for the local and national Economy of Kenya, economies, to preserve an area of great scenic beauty, to conserve the biodiversity within the park, and to preserve the water-catchment for the surrounding area. Area The national park has an area of , most of which is above the cont ...
