Association For The Taxonomic Study Of The Flora Of Tropical Africa
The Association pour l’Etude Taxonomique de la Flore d’Afrique Tropicale (AETFAT) is a scientific association for the study of the flora of Tropical Africa. Other names for the organization are the ''Association for the Taxonomic Study of the Flora of Tropical Africa'' and ''Verband für die Taxonomische Untersuchung der Flora des Tropischen Afrikas''. The association was planned by Edgar Milne-Redhead (Royal Botanic Gardens, Kew), Arthur Wallis Exell (British Museum), and Jean Joseph Gustave Léonard (Meise Botanic Garden) in 1949 and established at the Université libre de Bruxelles in 1951. A meeting, called a Congress, is held every three years, the latest one occurring in June and July 2022 in Livingstone, Zambia. AETFAT has sponsored a vegetation map of Africa Africa is the world's second-largest and second-most populous continent, after Asia in both cases.

Flora
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Africa
Although tropical Africa is mostly familiar to the West for its rainforests, this biogeographic realm of Africa is far more diverse. While the tropics are thought of as regions with hot moist climates, which are caused by latitude and the tropical rain belt, the geology of areas, particularly mountain chains, and geographical relation to continental and regional scale winds impact the overall areas , also, making the tropics run from arid to humid in West Africa. The area is currently experiencing the negative effects of rapid human population growth.Zinkina J., Korotayev A.br>Explosive Population Growth in Tropical Africa: Crucial Omission in Development Forecasts (Emerging Risks and Way Out). ''World Futures'' 70/2 (2014): 120–139 Overview Tropical rainforests are moist forests of semi-deciduous plants distributed across nine West African countries.

Edgar Milne-Redhead
Edgar Wolston Bertram Handsley Milne-Redhead (1906-1996) was a British botanist. He was born in Frome, Somerset, UK. Educated at Cheltenham College and Gonville and Caius College, Cambridge, he began work at the Royal Botanic Gardens, Kew in 1928. In 1930, he accepted an offer to work in the Colonial Office in Northern Rhodesia (now Zambia), where he collected plants for herbarium specimens. He was based at Matonchi Farm, west of Mwinilunga, North-Western Province, Zambia, near the borders of Angola and the Democratic Republic of the Congo for 4½ months. He also collected extensively near Kalene Hill. He discovered many new species, and several were named after him, including ''Commelina milne-redheadii'' Faden ( Commelinaceae). In 1933, he married Olive Shaw, with whom he had one daughter. In 1949, he and others began the process to establish an “Association pour l’Etude Taxonomique de la Flore d’Afrique Tropicale” (or “Association for the Taxonomic Study of the Flo ...

Royal Botanic Gardens, Kew
Royal Botanic Gardens, Kew is a non-departmental public body in the United Kingdom sponsored by the Department for Environment, Food and Rural Affairs. An internationally important botanical research and education institution, it employs 1,100 staff. Its board of trustees is chaired by Dame Amelia Fawcett. The organisation manages botanic gardens at Kew in Richmond upon Thames in south-west London, and at Wakehurst, a National Trust property in Sussex which is home to the internationally important Millennium Seed Bank, whose scientists work with partner organisations in more than 95 countries. Kew, jointly with the Forestry Commission, founded Bedgebury National Pinetum in Kent in 1923, specialising in growing conifers. In 1994, the Castle Howard Arboretum Trust, which runs the Yorkshire Arboretum, was formed as a partnership between Kew and the Castle Howard Estate. In 2019, the organisation had 2,316,699 public visitors at Kew, and 312,813 at Wakehurst. Its site at Kew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Wallis Exell
Arthur Wallis Exell OBE (21 May 1901, in Birmingham – 15 January 1993, in Cheltenham) was initially an assistant and later Deputy Keeper of Botany at the British Museum during the years 1924–1939 and 1950–1962. A noted cryptographer, taxonomist and phytogeographer, he was notable for his furthering of botanical exploration in tropical and sub-tropical Africa, and was an authority on the family Combretaceae. Exell's formal education started at Queen Elizabeth Grammar School in Warwickshire, and then King Edmund's School in Birmingham. From there he went on to Emmanuel College, Cambridge and was awarded an M.A. in 1926, having joined the British Museum as a second-class assistant on 11 August 1924, eventually becoming Deputy Keeper of Botany in 1950. He was entrusted with the Polypetalae, although his first paper was a morphological study of the hymenium in three species of fungus. Exell's first contact with Africa was in 1932/3 when he travelled to the islands in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Museum
The British Museum is a public museum dedicated to human history, art and culture located in the Bloomsbury area of London.

Meise Botanic Garden
The Meise Botanic Garden ( nl, Plantentuin Meise, french: Jardin botanique de Meise), until 2014 called the National Botanic Garden of Belgium ( nl, Nationale Plantentuin van België, french: Jardin Botanique National de Belgique), is a botanical garden located in the grounds of Bouchout Castle in Meise, Flemish Brabant, just north of Brussels. It is one of the world's largest botanical gardens, with an extensive collection of living plants and a herbarium of about 4 million specimens. The current garden was established in 1958 after moving from central Brussels; the former site is now the Botanical Garden of Brussels. The Meise Botanic Garden contains about 18,000 plant species—about 6% of all the world's known plant species. Half are in greenhouses, the other half, including cultivated and indigenous plants, are outdoors. The ''Index Herbariorum'' code assigned to this botanic garden is BR, which is used when citing housed specimens. The botanic garden's mission statement s ...

Zambia
Zambia (), officially the Republic of Zambia, is a landlocked country at the crossroads of Central Africa, Central, Southern Africa, Southern and East Africa, although it is typically referred to as being in Southern Africa at its most central point. Its neighbours are the Democratic Republic of the Congo to the north, Tanzania to the northeast, Malawi to the east, Mozambique to the southeast, Zimbabwe and Botswana to the south, Namibia to the southwest, and Angola to the west. The capital city of Zambia is Lusaka, located in the south-central part of Zambia.

Vegetation
Vegetation is an assemblage of plant species and the ground cover they provide. It is a general term, without specific reference to particular taxa, life forms, structure, spatial extent, or any other specific botanical or geographic characteristics. It is broader than the term ''flora'' which refers to species composition. Perhaps the closest synonym is plant community, but ''vegetation'' can, and often does, refer to a wider range of spatial scales than that term does, including scales as large as the global. Primeval redwood forests, coastal mangrove stands, sphagnum bogs, desert soil crusts, roadside weed patches, wheat fields, cultivated gardens and lawns; all are encompassed by the term ''vegetation''. The vegetation type is defined by characteristic dominant species, or a common aspect of the assemblage, such as an elevation range or environmental commonality. The contemporary use of ''vegetation'' approximates that of ecologist Frederic Clements' term earth cover, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
