Cyperus Clavinux
''Cyperus clavinux'' is a species of sedge that is endemic to parts of Africa. The species was first formally described by the botanist Charles Baron Clarke Charles Baron Clarke (17 June 1832 – 25 August 1906) was a British botanist. He was born at Andover, Hampshire, Andover, the eldest son of Turner Poulter Clarke. He was educated at King's College School, London, and at Trinity College, Cambrid ... in 1901.

Cyperus
''Cyperus'' is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions. Description They are annual or perennial plants, mostly aquatic and growing in still or slow-moving water up to deep. The species vary greatly in size, with small species only tall, while others can reach in height. Common names include ''papyrus sedges'', ''flatsedges'', ''nutsedges'', ''umbrella-sedges'' and ''galingales''. The stems are circular in cross-section in some, triangular in others, usually leafless for most of their length, with the slender grass-like leaves at the base of the plant, and in a whorl at the apex of the flowering stems. The flowers are greenish and wind-pollinated; they are produced in clusters among the apical leaves. The seed is a small nutlet. Ecology ''Cyperus'' species are eaten by the larvae of some Lepidoptera species, including ''Chedra microstigma''. They also provide an alternative food source for ...

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] |
Africa
Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area.Sayre, April Pulley (1999), ''Africa'', Twenty-First Century Books. . With billion people as of , it accounts for about of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, behind Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxa Named By Charles Baron Clarke
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1901
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...

Flora Of Zimbabwe
The wildlife of Zimbabwe occurs foremost in remote or rugged terrain, in national parks and private wildlife ranches, in miombo woodlands and thorny acacia or kopje. The prominent wild fauna includes African buffalo, African bush elephant, black rhinoceros, southern giraffe, African leopard, lion, plains zebra, and several antelope species. The introduction of the Wildlife Conservation Act of 1960 resulted in checking the loss of wildlife in Zimbabwe, since the 1960s. In the 1990s, it became one of the leading countries in Africa in wildlife conservation and management with a reported income generation US$300 million per year from the protected areas of the state, rural community run wildlife management areas and private game ranches and reserves. The Parks and Wildlife Board consisting of 12 members is responsible for this activity and deciding on policy issues under the Ministry of Environment and Natural Resources Management.

Flora Of Zambia
The wildlife of Zambia refers to the natural flora and fauna of Zambia. This article provides an overview, and outline of the main wildlife areas or regions, and compact lists of animals focusing on prevalence and distribution in the country rather than on taxonomy. More specialized articles on particular groups are linked from here. Overview Ecoregions Using the World Wildlife Fund's classification of ecoregions, Zambia may include miombo, mopane and Baikiaea woodland savanna, with grasslands (mainly flooded grasslands) and evergreen forest also present. The chief determinant of the distribution of ecoregions and wildlife is climate. See ''Climate of Zambia'' for more detail. Animals outside the national parks Zambia's "big game" wildlife (including sports fishing) is the foundation of its tourism industry now. One of its biggest employers and foreign-exchange earners: Victoria Falls and cultural events come second and third in importance. However for domestic tourism, this or ...

Flora Of Botswana
The wildlife of Botswana refers to the flora and fauna of this country. Botswana is around 90% covered in savanna, varying from shrub savanna in the southwest in the dry areas to tree savanna consisting of trees and grass in the wetter areas. Even under the hot conditions of the Kalahari Desert, many different species survive; in fact the country has more than 2500 species of plants and 650 species of trees. Vegetation and its wild fruits are also extremely important to rural populations living in the desert and are the principal source of food, fuel and medicine for many inhabitants. Three national parks and seven game reserves stretch over 17% of Botswana's land area. The three national parks are the Chobe National Park, the Nxai Pan and Makgadikgadi National Park and the Kgalagadi Transfrontier Park. The seven game reserves are the Central Kalahari Game Reserve, Gaborone Game Reserve, Khutse Game Reserve, Mannyelanong Game Reserve, Maun Game Reserve and Moremi Game Reserve. In ...

Flora Of Chad
The wildlife of Chad is composed of its flora and fauna. Bush elephants, West African lions, buffalo, hippopotamuses, Kordofan giraffes, antelopes, African leopards, cheetahs, hyenas, and many species of snakes are found there, although most large carnivore populations have been drastically reduced since the early 20th century. Elephant poaching, particularly in the south of the country in areas such as Zakouma National Park, is a severe problem. Vegetation As of 2011, there were 2,288 species in the country in the country, 55 of which are endemic. Precipitation varies widely from south to north of the country. The country is also subject to hot, dry, dusty conditions. Harmattan Winds are a feature in the northern part of the country. Droughts and locust plagues are also common. The vegetation in the country is broadly categorized under the three regions of the northern Sahara zone, the central Sahel zone, and the southern Sudan zone; all three zones are of equal proportion. ...

Flora Of Malawi
The wildlife of Malawi is composed of the flora and fauna of the country. Malawi is a landlocked country in southeastern Africa, with Lake Malawi taking up about a third of the country's area. It has around 187 species of mammal, some 648 species of birds have been recorded in the country and around 500 species of fish, many of them endemic, are found in its lakes and rivers. About 20% of the country has been set aside as national parks and game and forest reserves. Geography The flora and fauna are much influenced by the geography of the region. Malawi is a land-locked country, dominated by the Great Rift Valley which has a north – south orientation, and is long and between wide. The main feature is Lake Malawi which forms much of the eastern boundary of the country. The lake is drained by the Shire River which flows southwards to join the lower Zambezi in neighbouring Mozambique. Lake Malawi is above sea level but is deep in places. It is bordered on the west by a narrow pl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
